[[circled]] 1 [[/circled] dear "Wheet" or "Treet" Notes of Buff-throated Saltators really are hostile, this is a fact of some comparative interest. See also comments below. Buff-throated Saltators utter 2 types of Hoarse Notes. They utter Hoarse Screams which are apparently identical with those of Streaked Saltators. Captive individuals were heard to utter similar but shorter and (usually) much softer "whispered" notes during prolonged and violent disputes among themselves and with Streaked Saltators. These notes usually were uttered during contact fighting. Occasionally, they were uttered during long "lulls" between fights (where the combatants were exhausted) and/or immediately after a fight. In such cases, they were usually, or always accompanied by Gaping Move case, they were also accompanied by Belly-fluffing and dropping of the even gs (see below). They appeared to function as threat They probably were purely hostile and [[underline]] very [[/underline]] high intensity, produced when both attack and escape tendencies were very strong. The attack and escape tendencies may have been approximately equal to one another. Certainly escape was not as predominant as we all almost "Wheet" Notes, but attack may have been less predominant than in the Harsh Hoarse Notes of many related species. Buff-throated Saltators do not utter Hoarse Notes (considering all the Hoarse patterns as a unit) as frequently as do Streaked Saltators, CBT's or GBS's. They utter other calls and notes in many of the usual situations in which the latter species utter one or more type of Hoarse Notes. In this respect, Buff-throated Saltators resemble Yellow-winged Tanagers. It is possible, in fact, that the only two Hoarse Patterns of BTS's are strictly equivalent to the only two "pure" Hoarse patterns of Yellow-winged Tanagers, produced by the same combinations of tendencies, of similar strength, and [[?]]serving the same function(s). Wild Buff-throated Saltators were not heard to utter the softer type of Hoarse Note- probably because contact fights are relatively rare in
[[circled]] 2 [[/circled]] under natural conditions. Where there if plenty of room in which to maneuver, an attacked bird usually retreats from its attacker, at least temporarily Both wild and captive Buff-throated Saltators utter sharp "Trit" or "Tit" Notes very frequently. Sometimes their notes are uttered by themselves alone, [[underline]] i.e. [[underline]] not in close association with other types of vocal patterns (see also below). Sometimes they are uttered singly or repeated at relatively long (and irregular) intervals. Several individuals were heard to utter such patterns in ambiguous but probably largely hostile circumstances. It is possible that single "Trit" or "Tit" Notes are [[strikethrough]] largely or completely homologous with [[/strikethrough]] more or less closely related to the Short Hostile Notes of related species. They sound very much like the Short Hostile Notes of some populations of Silver billed Tanagers [[underline]] (Ramphocelus carbo)[[/underline]] and Black-throated Tanagers [[underline]] (R. nigrogularis) [[/underline]]. The typical Rattles of Buff-throated Saltators are more or less prolonged series of short, hard notes uttered in more or less rapid succession; but they probably are shorter and slower in tempo, on the average, than the typical Rattles of Yellow-rumped Tanagers or [[underline]] Chlorospingus [[/underline]] species. They usually begin abruptly. All or most of them could be transcribed as "Tuk tuk tuk tuk..." or "Tit tit tit tit...". Captive Buff-throated Saltators uttered Rattles most frequently during purely or predominantly hostile encounters, especially during chases. I think that the Rattles usually were uttered by the chasing birds rather than the birds being chased. In the wild, Rattles were heard to be uttered by individuals moving actively near other individuals who may have been other territorial rivals or potential mates. The individuals uttering Rattles in these circumstances sometimes performed overt hostile movements, and usually tended to advance toward their opponents or partners. Once, an individual uttered many Rattles (without any other calls or notes) while it performed many supplanting attacks. Once, another individual utt [[end page]]
[[circled]] 3 [[/circled]] [[utt]]ered many Rattles and many "Warbles" (see below) while pursuing a (presumably) territorial rival. Once, one or both birds of an apparently mated pair uttered a few ^ [[insertion]] typical [[/insertion]] Rattles when the two birds landed together. (This is certainly not, however, the only "Greeting" pattern of the species – see below.) It seems likely, therefore, that Rattles are at least partly hostile, and produced when the tendency to attack is at least slightly stronger than the tendency to escape. It is highly ^[[insertion]] probable [[/insertion]] that the Rattles of Buff-throated Saltators are nothing more than accelerated series of the "Trit" or "Tit" Notes sometimes uttered singly. Intermediate patterns occur occasionally. A bird many begin to utter single "Trit" or "Tit" Notes at relatively long intervals, and then utter more notes of the same type at progressively shorter intervals until the successive notes follow one another as rapidly as in typical Rattles. ^ [[insertion]] Several times, wild birds were heard to utter unusually soft but otherwise typical R's when joining other individuals, possibly their mates. There patterns were reminiscent of the "Muffled R"s of some related species. [[/insertion]] The most characteristic vocalizations of Buff-throated Saltators may be called "Warbles". These are composed of Flourishes alone or (more frequently) Flourishes and "Trit" or "Tit" Notes. Flourishes are clear, rather musical, bisyllabic or trisyllabic notes of moderate length and (usually) moderate loudness. Typical Flourishes could be transcribed at "Tseeyoo", "Tsawee", "Tasweeyoo," "Toa-ha-whee", and "Tsa-whee-whee". The different syllables of a single note are usually or always quite different in pitch, ^ [[insertion]] but the sequence of pitch changes is variable. [[/insertion]] The basic form or outline of these patterns seems to essentially identical with that of the Flourishes of [[underline]] Chlorospingus [[/underline]] species and Yellow-rumped Tanagers (and their motivation may be equally similar -- see below.) When they are uttered apart from "Trit" or "Tit" Notes, they are apparently always uttered in pairs or "doublets". Usually the two Flourishes of a single doublet are very similar to one another, having the same number of syllables and similar changes in pitch. In Warbles which include "Trit" or "Tit" Notes, the Flourishes ma[[y]] [[end page]]
[[circled]] 4 [[/circled]] [[ma]]y be either single or double. In many Warbles, there is only one "Trit" or "Tit" Note. In others, there may be two to six, uttered one right after the other in a tempo which is moderately rapid but noticeably slower than that of typical Rattles. Single notes and series of this type are usually or always uttered immediately before the first (or only) Flourish(es). In some series, all the notes are essentially similar or identical in pitch. In other series, one or more notes may be conspicuously higher or lower than the others. This variation is always irregular. Series are never consistently ascending or descending throughout. (It is, of course, the irregular variation of pitch, in conjunction with the moderately rapid rhythm that produces the actual warbling effect.) Warbles are uttered by solitary or single Buff-throated Saltators in exactly the same range of circumstances, during the breeding season, and during the same periods of the day, as the Day Songs of Streaked Saltators. They probably also are true songs. A solitary bird uttering Warbles is usually joined by its mate or potential mate. Warbles also are uttered in a variety of possibly or certainly hostile circumstances. They are common during disputes between territorial neighbors,and between individuals of the same sex in captivity. Some tunes they are combined with obviously hostile Bill-up Postures (see below) They may be uttered as a sort of "triumph ceremony" by the victor of a fight, after its opponent as fled. They may be uttered as "greeting" by mated birds when one joins the other or both land together. As far as I could tell, all types of Warbles are uttered in every one of these situations (although not necessarily with equal frequency) It seems likely that Flourishes are at least partly sexual, as they are similar to Dawn Calling Notes in sound (see below). The "Trit" or "Tit" Notes are almost certainly at least partly hostile (this is indicated by their relationship to Rattles) Although Warbles sound quite different from the Day Songs of Str[[eaked]] [[end page]]
[[circled]] 5 [[/circled]] eaked Saltators, they are probably homologous with part of the latter when the two patterns are analyzed in detail, certain striking similarities in form are apparent. The fluctuations of pitch in some Flourishes is similar to that in the Whistles of Panamanian Streaked Saltators. The grouping of Flourishes in doublets is paralleled by the double Whistles of the Streaked Saltator studies in Chiriquí. The "Trit" or "Tit" Notes occur before Flourishes in the same way that the "Duh" Notes occur before Whistles, and the rhythm of series of "Tut" or "Tit" Notes is similar to that of series of "Duh" notes. [[Note: following paragraph has a vertical line in margin]] The "songs" of Costa Rican Buff-throated Saltators which Skutch transcribes as "cheery cheery" and "cheer to your" may be Flourishes like those of Panamanian birds. Skutch says that these patterns usually are sung responsively by mated birds. He apparently did not hear them during obviously hostile encounters. It is possible, however, that some of the groups of two individuals which he took to be mated pairs were, in fact, territorial rivals or opponents. The Warblers of Panamanian Buff-throated Saltators frequently are associated with typical Rattles. Rattles may be uttered immediately before and/or after Rattles The sequence of one Rattle followed by one Warble is by far the most common Many of the Warbles following immediately after Rattles seem to be composed of Flourishes and only one "Trit" or "Tit" Note (the single "Trit" or "Tit" being separated from both the piece during Rattle and the following Flourish by very brief pauses). It seems possible that preceding Rattles tend to "absorb" the usual slower series of "Trit" or "Tit" Notes. ^ [[insertion]] The Rattle may even affect the Flourish part of a Warble. The Flourishes of one captive individual acquired a rattling undertone when it uttered many Rattles and Warbles during a prolonged dispute [[/insertion]] The Rattle-Flourish Songs of Brown-capped Bush-tanagers Similarly, the Warble-Rattle sequences seem to be completely homologous with the whole of the complete Day Songs of Streaked Saltators. Occas[[ionally]] [[end page]]
[[circled]]6 [[/circled]] ionally, Buff-throated Saltators utter one "Jit" or "Jit" Note immediately before a Rattle-Flourish sequence. These performances may be largely or completely homologous with the "Izzbeet" Note-Then Rattle-Hoarse Flourish patterns of Yellow-rumped Tanagers and/or the "Jit"-Rattle-Flourish patterns of Brown-capped Bush-tanagers. The whole Warble pattern, with or without Rattles, also is startlingly reminiscent of some warbling patterns of [[underline]] Altapetes [[/underline]] and other bush finches. Buff-throated Salatators seem to utter Rattle-Warble combinations in much the same range of circumstances as typical Rattles alone. There are some indications, however, that individuals uttering both Rattles and Warbles are somewhat less aggressive, on the average, than individuals uttering only Rattles. Combinations of Rattles and Warbles are among the more common "Greeting" patterns. The Warbler and Rattle-Warble sequences of individuals not actively engaged in chases or actual fights are combined with Bill-up Postures or, much more frequently, unritualized upright sitting postures similar to the postures accompanying Dawn Calling (see figures___) Dawn Calling is probably the least distinctive vocal pattern of the species. It usually is uttered in the same range of circumstances as the Dawn Calling of Streaked Saltators and many other finches and tanagers. The individual Dawn Calling Notes are very similar to those of Streaked Saltators in tone. Some of them may also be identical in form; but most of them are longer and include more syllables, up to four or five in many cases. Buff-throated Saltators are particularly apt to utter two slightly different types of notes, one having one more syllable than the other; in very regular alternation. Typical Dawn Calling series might be transcribed as "Whee-ew whee-a-ew whee-ew whee-a-ew..." and "Tee-a-a-weeyoo tee-a-weeyoo tee-a-a-weeyoo tee -a-weeyoo..."
[[circled]] 7 [[/circled]] (Skutch transcribes the Dawn Calling of Costa Rican Buff-throated Saltators as "tralé le-e-le, trale'le-e-le...".) All Dawn Calling notes of this type, by themselves alone, sound very much like Flourishes. The Dawn Calling of one captive individual included a few single, loud, harsh "Cheewink" Notes (all or most of which had rattling undertones), interjected at irregular intervals among softer five-syllabled notes of the usual type. These "Cheewink" Notes probably are related to the Rattles and semi-rattling notes in some Dawn Calling performances of Streaked Saltators and Crimson-backed Tanagers. The Dawn calling of Buff-throated Saltators usually is not accompanied by special movements. But one captive bird (not the individual that uttered "Cheewink"s) was observed to perform slight wing movements during one burst of Dawn Calling. It flicked its wings upward, a fraction of an inch, each time it uttered a note, and lowered them again (to the usual resting position) between notes. I think that the wings also were quivered very briefly, slightly, and rapidly while they were raised. This was reminiscent of the more exaggerated "Upward Wing-quivering" which accompanies the Dawn Calling of Brown-capped Bush-tanagers (and at least one species of [[underlined]] Atlapetes) [[/underlined]]. The hostile repertory of Buff-throated Saltators includes both special movements and ritualized postures, in addition to the calls and notes cited above. Among these ^ [[insertion]] non-vocal patterns [[/insertion]] are Gaping, "Crest-raising", Bowing (and Pivoting) Head-lowered Postures, Bill-up Postures, Lateral Fluffing, and Belly-ruffling. Bill-up Postures were observed to be performed by both captive and wild individuals. All the other patterns were seen only during disputes among captive individuals. Crest-raising may have been overlooked in the wild because it is inconspicuous. The remaining patterns probably are produced only when motivational conflict is very strong. They were observed only during prolonged disputes between individuals in close proximity to one another. They may be perfor [[end page]]
[[circled]] 8 [[/circled]] [[perfor]]med relatively rarely in the wild simply because prolonged "close-range" disputes are rare under natural conditions (see above). the Gaping seems to be basically similar to that of Streaked Saltators in form. It is almost confined to actual fights. It may be silent or (less frequently) accompanied by Hoarse Notes. It usually is not combined with other display components (except ordinary locomotory patterns); but once a bird was seen to perform brief Gaping while sitting in a rather hunched posture with Crest-raising and Belly-ruffling at the end of a particularly prolonged dispute (see below). The Gaping of Buff-throated Saltators may be slightly less aggressive than the corresponding pattern of many related species. It often is performed by individuals which appear to be slightly on the defensive. It seems to function as threat. Crest-raising is a simple erection of all the feathers of the crown (see figure____) It is inconspicuous because the crown feathers are not lengthened. It is most frequently performed by itself alone, without any other display. I have seen individuals perform simple Crest-raising of this type as a reaction to the mere approach of other individuals. Occasionally, Crest-raising is accompanied by Belly-ruffling, Gaping, Bowing, Warbles and/or Rattles. Very rarely, there may be a slight trace of Crest-raising (partial erection of the crown feathers) superimposed upon Head-lowered or Bill-up Postures. It is possible that the Crest-raising of Buff-throated Saltators is primarily an expression of escape motivation, like the morphologically similar patterns of many related species. The Head-lowered Posture is not very exaggerated in form, and may be only slightly ritualized. The head is brought down to shoulder level, while the bill points straight forward. This is usually, but not always, accompanied by Lateral Fluffing (see figure___). Head-lowered Postures may
[[circled]] 9 [[/circled]] be combined with pivoting, and may be used as the "low position" during Bowing (see below). They obviously are aggresive They are assumed most frequently by attaching birds immediately before attack. In Lateral Fluffing, all the feathers of the flanks and sides are raised. This greatly increases the lateral dimensions of the bird performing the patter. Such a bird looks [[underline]] very [[/underline]] broad when viewed from the front or rear. In all or most Lateral Fluffing,the feathers also are erected in such a way as to form two "tufts" or "peaks" on each side, rising diagonally upward to cover the lower edges of the wings. The anterior tufts may be large and conspicuous enough to look like "false wings". (This is difficult to describe in words, but it is illustrated in figure----) Lateral Fluffing is almost an integral part of the Head-lowered pattern. the only other postures with which it may be associated are some unusual Bill-up patterns which probably are partly intermediate between typical Bill-up Postures and typical Head-lowered Postures. In typical bill-up Postures, the head and bill are pointed almost vertically upward, while the body and tail remain in a diagonal position or appearance or approximately horizontal(see figure---). Most Bill-up Postures are accompanied by some degree of Belly-ruffling. The wings are usually drooped, but not spread, except when Lateral Fluffing is alse present. Bill-up Postures are usually silent. They often serve on "high postures" during Bowing, and may be combined with pivoting. Occasionally, they are accompanied by Warbles, Rattles, and/or "Wheet" notes. They obviously are less aggressive than Head-lowered Postures. They are performed immediately before escape as well as attack. Bowing is a more or less rapid alternation of up and down movements. A Bowing bird alternately stands with its head held high and with its head held low. Performances of this type are stereotyped enough to suggest that they have become slightly ritualized , but they are variable as some aspects of for
[[circled]] 10 [[/circled]] m. Sometimes the high postures are Bill-ups. Sometimes they are nothing more than ordinary "alert-looking" upright postures. Sometimes the low postures are extreme Head-lowered Postures more often they are less exaggerated. In many cases, the downward component of Bowing is nothing more than a brief downward "flick" of the head and neck. The time spent in low and high phases is different in different Bowing performances, and may even vary within a single performance, presumably in accordance with the (relative) level of aggressiveness in the performing birds. Pivoting is composed of lateral movements. A pivoting bird looks from side, usually switching the whole head, and body together. This is much more irregular in form than Bowing, and probably is not ritualized [[underline]] per se. [[/underline]] It may be combined with, or alternated with, or performed quite apart from Bowing. It obviously is the result of conflicting tendencies to advance and retreat. Both Bowing and pivoting usually are accompanied by Wing-[[fl?]] and Tail-flicking movements and extreme Tail-fanning. The Bill-up Postures, Bowing and pivoting of Buff-throated Saltators are very reminiscent of [[underline]] Atlapetes [[/underline]] and other bush-finders, many of which perform similar (or even more exaggerated) patterns in similar circumstances. The Belly-ruffling of Buff-throated Saltators is a raising of all the feathers of the lower breast and belly. They usually or always are raised in such a way that their tips are conspicuously separated from one another. A moderate degree of Belly-ruffling usually accompanies Bill-up Postures (see figure ____). The most extreme Belly-ruffling observed was performed by an exhausted and defensive individual which had been chased and attacked, repeatedly, by another individual over a period of a half hour or more. This was combined with [[?]]-raising, Lateral Fluffing, and (briefly]) Gaping (see fig ____). The whole combination of patterns was very reminiscent of the "Flu[[ffed]] [[end page]]
[[circled]] 11 [[/circled]] [[flu]]ffed "Hunched" patterns of many related species. Buff-throated Saltators were not observed to perform copulatory patterns. Perhaps they tend to copulate in denser vegetation than do Streaked Saltators THE GRAY SALTATOR [[underline]] (S. coerulescens) [[/underline]] A few Gray Saltators were observed in the countryside near Iquitos, Peru, between December 14 and December 24, 1958. They were found along the edge of second growth forest and scrub, and did not seem to be more gregarious than other species of the genus. According to Hellmayr [[underline]] (op. cit.), [[/underline]] the Gray Saltators of this region belong to the subspecies [[underline]] azarae. [[/underline]] Some individuals (known or presumed males) uttered loud phrases which appeared to be Day Songs whenever they found themselves alone. These phrases were composed of "Duh" Notes and Whistles which sounded very much like the corresponding patterns of Streaked Saltators. The form of the phrases was somewhat variable. One individual, for instance, uttered some phrases which consisted of four or five "Duh" Notes followed by one lone Whistle, and other phrases of one "Duh" Note followed by two long Whistles followed by two more "Duh" Notes followed by one more, rather short, Whistle. Most Day Songs were uttered from the rather exaggerated, but not necessarily ritualized, upright posture illustrated in figure _____. Some of the same individuals also uttered much softer phrases composed of a few "Duh" Notes followed by one Rattle. One individual (at least) uttered three soft phrases when it was "semi-isolated", [[underline]] i.e. [[/underline]] when there was another individual (possibly its mate) in the neighborhood but not close by. Several individuals were heard to utter metallic (and possibly slightly nasal) "Trit" notes [[end page]]
[[circled]] 12 [[/circled]] Perhaps the most interesting vocal patterns were Hoarse Notes. They usually were uttered in series (sometimes very long series) which might be transcribed as "Kanh kanh kanh kanh...". They were uttered most frequently as "Greeting" patterns, whenever one bird landed beside another (presumably its mate, in all the cases I observed). These performances were very reminiscent of the series of Medium Hoarse Notes and "chah" Notes uttered by Green-backed Sparrows and Streaked Saltators in similar circumstances. Unlike the latter species, however, the Gray Saltators also uttered many Hoarse Notes during "Duets" between mated birds quite apart from "Greetings" or landing. It was not uncommon to hear an individual utter a series of Hoarse Notes while it was sitting beside its mate, after the two birds had been close together, continuously, for some minutes. In most cases, the mate responded by uttering a similar series of Hoarse Notes. Usually the responding bird began its Hoarse Notes only a few seconds after the first, and the series of the two birds overlapped very broadly. Sometimes one member of a pair would utter a few "Tut" Notes and/or Day Song notes in addition to (perhaps even instead of) Hoarse Notes during a Duet. Sometimes the members of a pair would Duet repeatedly at very short intervals. In most cases, it was impossible to identify the stimulus releasing Duetting. Duetting birds usually did not perform overt hostile movements. In one peculiar case, a known male repeatedly began to utter Day Songs while sitting close to a presumed female. Each time it did this, its partner responded by uttering a series of Hoarse Notes. As soon as this began, the male stopped its Day Song phrase and began to utter Hoarse Notes too. The Hoarse Notes obviously are very contagious. [[insert]] The Duetting of GS's is very reminiscent of BHS's (see below). [[/insert]] One apparently successful copulation attempt was observed. The female performed elaborate displays beforehand, while the male was several yards away from her. First she uttered a few single notes that were both metallic and strongly nasal. These might be transcribed by something like "Auh". Then she assu
[[circled]] 13 [[/circled]] med a Bill-up Tail-up Posture, ruffled her belly feathers, and performed Wing-quivering with her wings held out and slightly drooped (see figure -). At the same time she uttered several Hoarse Notes, (probably) followed by one soft Rattle. After the copulation, one or both birds uttered more Hoarse Notes. THE BLACK-HEADED SALTOTOR [[underlined]](S. atriceps)[[/underlined]] Black-headed Saltators were studied in most of the same areas of central Panama, during the same period of time, as Buff-throated Saltators.

[[circled]] ^[[1]] [[/circled]] DISPLAY PATTERNS OF TROPICAL AMERICAN "NINE-PRIMARIED” SONGBIRDS V. [[underlined]] Saltator [[/underlined]] M. Moynihan This is the fifth in a series of papers on the ritualized, social signal, behavior patterns of some tropical American finches, tanagers, and honeycreepers. The preceding papers of the series were concerned with the genera [[underlined]] Chlorospingus, Ramphocelus, and Arremonopa [[/underline]] (Moynihan, 1962b, 1962c, 1963, and 1965). The following account will include brief descriptions of some patterns of five species of [[underline]] Saltator, [[/underline]] large “grosbeak” type finches. These species were not studied in detail, but enough of their behavior was seen to permit a partial evaluation of the comparative position of the genus. THE STREAKED SALTATOR [[underlined]](S. albicollis) [[/underline]] Wild individuals of this species were observed in the Canal Zone and adjacent parts of the Republic of Panama at irregular intervals between March, 1958, and April, 1962. In addition, a few individuals were trapped in some of the same areas, and kept and studied in large aviaries on Barre Colorado Island. According to Hellmayr (1938), all these birds should have been representatives of the subspecies [[underline]] isthmicus. [[/underline]] Like all the other species of the genus with which I am familiar, Streaked Saltators seem to prefer “edge” habitats, especially the edges of second-growth vegetation, scrub and small trees. They seldom go very far inside dense scrub, and [[strikethrough]] [[?]] [[/strikethrough]] usually range from three to twenty-five feet above the ground, seldom or never coming down to the ground itself. Some aspects of their general social behavior in Panama are described in Moynihan (1962a). They are not very gregarious. They [[strikehthrough]] [[?]] [[/strikethrough]]^[[handwritten]] MAY OCCUR SINGLY OR IN
[[Handwritten]] 2 pairs or ^[[handwritten]] (IN THE BREEDING SEASON) IN [[/handwriting]] small family groups of parents with one brood of (one or two) )[[/strikethrough]] young. [[strikethrough]] in the breeding season. In the non-breeding season, individuals are usually alone. [[/strikethrough]] They usually do not associate with mixed flocks or individuals of other species during either the breeding or non-breeding seasons. The account in Skutch (1954) would suggest that the general social habits and habitat preferences of Streaked Saltators in Costa Rica and Colombia are much the same as in Panama. There is nothing very distinctive about the locomotory movements or intention movements of Streaked Saltators or any other species of the genus with which I am familiar. They all perform ritualized Wing-flicking and Tail-flicking movements which are not significantly different, in form, from those of [[underline]] Ramphocelus [[/underline]] species or the Green-backed Sparrow [[underlined]](Arremonops conirostris) [[/underline]]. As in the latter species, Tail-flicking is often accompanied by fanning of the tail feathers. The unritualized and slightly ritualized hostile movements and postures of Streaked Saltators seem to be equally undistinguished in form, but comparatively very rare, under natural conditions. Single individuals and mated pairs [[strikethrough]] of this species [[/strikethrough]] apparently maintain territories or exclusive home ranges. The same individuals are found in the same areas for (at least) months on end. But I never saw an actual fight, or even close contact, between presumably territorial neighbors in the wild. The most vigorous hostile reactions observed were performed by a captive individual during disputes with a Buff-throated Saltator. Its hostility took the form of Gaping (sometimes silent, sometimes accompanied by Hoarse Notes --- see below) and “head forward threat” postures (sometimes with Gaping, more often without). Most of the displays of Streaked Saltators are vocal. Among them are “Tsit” Notes, a variety of Hoarse Notes, Day Songs (including “Duh” Notes, Whistles, and Rattles), and Dawn Calling. “Tsit” Notes are sharp, thin, and not very loud. They may be uttered singly or in irregular series. They are uttered in a variety of circumstances, when
[[Handwritten]] 3 [[/handwriting]] several individuals are more or less close together. Sometimes they are accompanied by escape movements or intention movements. They may be “contact” or “call” notes or (alternatively) alarm notes. (These “Tsit” Notes may be the same as the “tseek” notes which Eisenmann, 1954, heard uttered by wild Streaked Saltators on Barro Colorado Island.) The Hoarse Notes can be divided into three main types. An individual caught in a trap (or held in the hand) utters long, loud, urgent-sounding “Hoarse Screams^”, quite like those of many related species. These probably are purely hostile and high intensity, [[underlined]] i.e. [[/underline]] produced by very strong motivation. Similar but softer notes were uttered by the captive individual disputing with a Buff-throated Saltator. They were closely associated with overt attack movements, and presumably were aggressive and of moderate intensity. They appeared to be essentially identical with the “Harsh Hoarse Notes” of Green-backed Sparrows and Crimson-backed Tanagers [[underlines]] (Ramphocelus dimidiatus)[[/underline]]. Both these types of Hoarse Notes seem to be much less common than the third type, which may (for want of a better name) be called “Chah” Notes. “Chah” Notes are usually or always uttered in short series. In many series, the successive notes become progressively shorter and lower in pitch; but all the notes of some series are slightly longer than the corresponding notes of other series. The longest “Chah” Notes may be slightly bisyllabic and could be transcribed as “Cha-ah”. The shortest notes end very abruptly and might be transcribed as “Chak” (some are almost “Chuk”). Intermediates between the longest and shortest notes are common, [[underlined]] i.e. [[/underline]] the two extremes seem to intergrade completely. “Chah” Notes of all types are uttered most frequently when one individual joins another (its mate or another member of its own family group) and when two or more individuals are moving about in more or less close proximity to one another. Occasionally, they are uttered by apparently single individuals landing alone. Thus, they appear to be “greeting” or “landing” patterns like the “Medium Hoarse Notes” of Green-backed Sparrows. The longer “Chah” Notes also
[[handwritten]][[circled]] 4 [[/circled]][[/handwritten]] sound very much like Medium Hoarse Notes. This would suggest that the two patterns are, in fact, closely related, perhaps even strictly homologous. The shorter ”Chah” Notes sound somewhat intermediate between the other Hoarse Notes and the “Short Hostile Notes” of Green-backed Sparrows and some other finches and tanagers. They may be related to both. (This is not really surprising. Even in the case of the Green-backed Sparrow, and in other species such as the Yellow-rumped Tanager. [[underlined]] Ramphocelus flammigerus icteronotus, [[/underline]] there are indications that Hoarse Notes and Short Hostile Notes are [[strikethrough]] related or [[/strikethrough]] linked to one another in some way.) It is possible that all the “Chah” Notes of Streaked Saltators, although occurring in ambivalent situations, are purely hostile (as the Medium Hoarse Notes of Green-backed Sparrows seem to be). The longer “Chah” Notes are not very different in sound from the Harsh Hoarse Notes. They may be more aggressive than the shorter “Chah” Notes. (The Short Hostile Notes of other species seem to be produced when the escape tendencies are at least slightly stronger than the attack tendencies.) All or most of the “Chah” Notes may be lower intensity, produced by weaker motivation ^[[insertion]] [[handwritten]] ON THE AVERAGE, [[/handwritten]] [[/insertion]] than the Harsh Hoarse Notes. Skutch ([[underline]] op. cit. [[/underline]]) Mentions “qua qua qua...” notes uttered by Costa Rican Streaked Saltators in flight. These may be the same as, or closely related to, the notes called “Chah” above. During the breeding season, isolated and apparently single birds, presumably unmated males or males separated from their mates*, perform Dawn Calling early in the morning. As in related species, the Dawn Calling takes the form of series of notes uttered at regular intervals. The length of the series is indeterminate, ranging from very brief to very long (I heard one bird utter Dawn Calling notes almost without interruption for over an hour). Most of the notes in the Dawn Calling of Streaked Saltators are clear in tone (but not whistling) and could be *It is usually impossible to distinguish between male and female saltators (of any species) by appearance alone in the field.
[[handwritten]][[circled]] 5 [[circled]][[handwritten]] transcribed as “Kew” or “Kioo”. They sound very much like the most common notes in the Dawn Calling of Crimson-backed Tanagers (which are abundant in many of the same areas as Streaked Saltators). It is, in fact, sometimes impossible to tell which species is uttering the notes when the performing individual is not in sight. Most of the “Kew” or “Kioo” Notes uttered by Streaked Saltators are very uniform in pitch. Sometimes, however, single notes which are very much higher in pitch but otherwise similar to ordinary ”Kew”s are interjected in the series at irregular intervals. All or most Dawn Calling performances also include single brief Rattles, or “Kew” Notes with a pronounced rattling “undertone”, as well as the clear notes. These rattling notes may be uttered in regular alternation with typical “Kew” or Kioo” Notes, or interjected less frequently and apparently at random. These performances are reminiscent of the Dawn Calling performances of Crimson-backed Tanagers in which single guttural or semi-rattling “Kraa” or Kraanh” Notes are interjected among typical “Kew”s. It seems very likely that the Dawn Calling of Streaked Saltators, or at least their “Kew” or “Kioo” Notes, are also similar to the corresponding patterns of related species in being produced by (thwarted) sexual motivation and functioning as a signal to attract or summon mates or potential mates. The dawn “song” of Streaked Saltators in Costa Rica which Skutch transcribes as “chip rrr chup chup chip rrr...” is probably Dawn Calling like that of the Panamanian birds. Eisenmann transcribes what seems to be Dawn Calling by Streaked Saltators on Barro Colorado Island as “chee-oo, chee-oo, chee-oo, cheeeee-oo” etc. The most characteristic vocalizations of Streaked Saltators in central Panama are Day Songs. These are series of extremely varied notes. The series are always brief, [[underlined]] i.e. [[/underlined]] more or less determinate in length. A typical “complete” Day Song begins with two or three short and rather “colorless” notes, each of which might be transcribed by something like “Duh”. When three of these notes are uttered, the interval between the first and second notes usually is longer than the interval between the second and third notes. The first note often is
6 [[handwritten and circled in upper right corner]] slightly higher in pitch than the second (and third). These introductory notes are followed by a long, clear, loud, and rather melodious Whistle. A typical Whistle might be transcribed as “Wheeeeeooooo”. It usually begins at a high pitch and then descends steadily, or begins moderately high, ascends briefly, and then descends. The Whistle is followed by a Rattle, usually or always longer than the Rattles during Dawn Calling. This ends the performance. The whole series of notes can be represented in diagrammatic form as follows: [[There is only blank space]] Performances of this type apparently are uttered only by single or isolated birds, unmated or separated from their mates, during the breeding season. They probably [[There is an arrow pointing left (to nothing) above the p in probably]] are “true” songs, as the term is used in this series of papers. They probably attract individuals of the opposite sex and repell other individuals of the same sex. I was not able to prove this conclusively (because there were no overt reactions between neighbors or rivals); but the evidence, such as it is, is highly suggestive. Certainly, a bird uttering these patterns is usually joined by its mate (or a potential mate) sooner or later.[[there are a few struck through words which can't be read]] And the form of the various notes would suggest that the motivation of the performance as a whole is ambivalent in the way that would be expected of true song. Rattles appear to be purely or predominantly hostile in all related species in which it has been possible to analyze their motivation. The “Duh” Notes seem to be related to hostile patterns of Buff-throated Saltators (see below). The Whistles, on the other hand, may be largely or completely sexual. Almost all the patterns of related species which are equally clear in tone, without any hoarseness or harshness or any trace of rattling, are known to be produced by sexual and/or other “friendly” tendencies. Streaked Saltators tend to utter these patterns most frequently during the middle part of the morning, after Dawn Calling has ceased, and may continue
[[handwritten and circled]] 7 [[/handwritten]] then throughout the day. The temporal distribution of these patterns is very reminiscent of the ”Rattle - Flourish Day Songs” of Brown-capped Bush-tanagers [[underline]] (Chlorospingus opthalmicus) [[/underline]]. Some of the probable relationships between the individual components of Streaked Saltator Day Songs and vocalizations of other finches and tanagers will be discussed in more detail below, after the corresponding patterns of other Saltators have been described. The Day Songs of Streaked Saltators in central Panama are quite stereotyped in form. Only two variations are common. Sometimes the terminal Rattle is omitted. Sometimes an extra, fourth, introductory “Duh” Note is inserted before the Whistle. There may be considerable differences between the Songs of Streaked Saltators in different regions. All the Song phrases of one individual studied near Cerro Punta on the Volcan de Chiriqui in western Panama were composed of introductory notes like those of the birds in central Panama, followed by one long Whistle, followed by one short Whistle, followed by another “Duh” Note. The Whistles themselves had a faint rattling undertone, but there were no pure Rattles. The only pattern of Costa Rican Steaked Saltators described by Skutch which might be closely related to part of the Songs of the Panama birds is “a refrain of four or five whistled syllables, forming an exquisitely modulated crescendo, and with the last syllable the longest”. All Panamanian Streaked Saltators utter their Day Songs from largely or completely unritualized erect sitting postures (see figures 1a and 1b). The major ^[[handwritten]] TYPES OF [[/handwritten]] vocal patterns (or groups of patterns) of Panamanian Streaked Saltators are quite “discrete”. They do not intergrade with one another to any appreciable request. In this respect, Streaked Saltators resemble most other finches and tanagers and are very different from Yellow-rumped Tanagers. Three copulation attempts by Streaked Saltators were observed in central Panama. Two of these began when the male flew straight on to the back of the
[[handwritten]] 8 [[/handwritten]] female, uttering “Chah” Notes in flight. One of these copulation attempts was apparently successful, the other obviously unsuccessful. In neither case was there any other display by either bird before, during, or immediately after the attempt. The third attempt was a little more elaborate. A female landed in a tree, uttering “Chah” Notes as she did so. Then she [[strikethrough]] shut up [[/strikethrough]] ^[[insertion]][[handwritten]] FELL SILENT [[/handwritten]] [[/insertion]], but assumed a Bill-up Tail-up Posture, with her breast lowered and all the plumage of the lower breast and belly fluffed or ruffled. At the same time, she stretched her wings out horizontally, but apparently did not quiver them. Then a male, who had been perched quietly in a tree about twenty feet away, flew straight on to her back and began copulatory movements immediately. The copulation was apparently successful. There was no post-copulatory display, but the two birds eventually flew off together uttering “Chah” Notes. THE BUFF-THROATED SALTATOR [[underlined]] (S. maximus) [/underlined]] Wild individuals of this species were studied in the same areas of central Panama as Streaked Saltators between March, 1958, and April, 1962; and captive individuals also were kept in aviaries on Barro Colorado Island. According to Hellmayr [[underlined]] (op. cit.) [[/underlined]], these birds should have been examples of the subspecies [[underlined]] intermedius [[/underlined]]. Buff-throated Saltators are larger than Streaked Saltators but somewhat more slender in build. They often occur along the edges of scrub and second-growth forest which is somewhat taller (and presumably older) on the average than the scrub preferred by Streaked Saltators; but the territories or home ranges of individuals of the two species may be broadly or completely overlapping in many areas. Individuals of both species sometimes occur in the same trees. They may even sit or feed in the same branches --- but apparently never simultaneously. I have never seen (or heard) any overt, positive, reaction between individuals of the two species (but this does not necessarily mean that the
[[handwritten]] [[circled]] 9 [[/circled]] [[/handwritten]] behavior of either one or both species is not influenced by the presence or proximity of the other). The general social behavior of Panamanian Buff-throated Saltators is strikingly different from that of Panamanian Streaked Saltators in one important respect. The Buff-throated Saltators of this region are not openly very gregarious among themselves. Individuals of different pairs or family groups do not usually join or follow one another in a "friendly" manner, or associate with one another in flocks. But territorial neighbors do approach one another with some appreciable frequency. (This must be an "intrinsic" difference between the two species, as populations of the two species seem to be approximately equally dense in many areas of central Panama.) As far as I could tell, all or most of the encounters between neighboring Buff-throated Saltators are largely or completely hostile. Panamanian Buff-throated Saltators certainly perform many more overtly hostile behavior patterns than Streaked Saltators in the same areas. They seem to be particularly likely to perform many conspicuously aggressive [[strikethrough]] movements [[/strikethrough]] ^[[insertion]] [[handwritten]] PATTERNS [[/handwritten]] [[/insertion]], such as supplanting attacks and chases. The account of Costa Rican Buff-throated Saltators in Skutch ( [[underlined]] op. cit. [[/underlined]] ) would suggest that their general social behavior is at least very similar to that of the Panamanian birds. But Skutch also says that Carriker and others found Buff-throated Saltators in small flocks in some parts of Central America. It is possible, therefore, that gregarious tendencies are among the factors that cause Panamanian Buff-throated Saltators to approach one another, even when the approaches are not obviously friendly. Panamanian Buff-throated Saltators may be associated with individuals of other species, of other genera, somewhat more frequently than are Streaked Saltators (Moynihan, 1962a); but this may be largely due to the fact that other species, especially those species which form mixed flocks among themselves, are more common in the trees preferred by Buff-throated Saltators than in the lower vegetation preferred by Streaked Saltators.
[[pencil encircled]] 10 [[/pencil]] [[insert pencil]] The VOCAL REPERTORY[[/insert]] [[strike out]] The displays[[/strikeout]] of Panamanian Buff-throated Saltators [[strikeout]] include Gaping, [[/strikeout]] [[insert pencil]] INCLUDES[[/insert]] "Wheet" Notes, Hoarse Notes, "Tsit" Notes, Rattles, Flourishes, [[insert pencil]] AND [[/insert]] Dawn Calling. [[strikeout]] various ruffling and fluffing patterns, Bill-up Postures and (probably) several other special postures and movements. The Gaping seems to be basically similar to that of Streaked Saltators in form. It may be silent or (occasionally) accompanied by Hoarse Notes. It was observed only during disputes among captive individuals, usually prolonged and vigorous disputes.[[/strikeout]] The "Wheet Notes (all or most of which might be equally well transcribed as "Tseet") are clear, fairly high pitched notes of moderate length. They may be uttered singly or in series, sometimes short, occasionally long. They are uttered in a great variety of more or less ambiguous situations. I have heard such notes uttered by apparently single birds in the wild, by one or both birds of pairs in the wild, and by captive birds in close association with both overtly hostile and overtly sexual patterns. They are uttered much more frequently by birds in flight, or hopping rapidly from perch to perch, than by birds sitting still. Thus, they could be purely locomotory "flight calls" and/or hostile signals and/or sexual signals. It may be significant, however, that the longest and most rapid series of such notes heard during the present study were uttered by captive individuals escaping from more aggressive individuals during particularly violent disputes. This would suggest that many, perhaps all, "Wheet" Notes are purely or predominantly hostile, and produced when the tendency to escape is stronger than the tendency to attack. They may be related to the "Tsit" Notes of Streaked Saltators, and subserve the same or similar functions. (In many, perhaps most, other tanagers and [[insert]]NEW WORLD[[/insert]] finches, vocalizations which include clear "ee" sounds are purely or predominantly sexual.

The voice of the Streaked seemed to be much clearer & purer than that of the Buff-throated. Both birds occasionally uttered single notes instead of the doublet. And the Buff-throated (at least) occasionally uttered triplets. Now one of the Buff-throats came back to the same tree, sat in the same way, but uttered different sounds. More elaborate: "Duh duh duh duh duh whoooo-ooo". Perhaps like this -- __ -- __ -- [[last line starts on the blue line of notepaper and gradually raises]] ???

A Streaked we flushed this afternoon, immediately flew to the top of a tall bare tree, landing with 3 or 4 "chuck"-like CN's which sounded quite remarkably like some of the "landing" CN's of Palm Tanagers in some circumstances. Saltator, I. [[right margin]] March 14, 1958 K-6 Flushed another Streaked from low shrubbery this afternoon, and the bird hopped around in the nearly bushes uttering quite a lot of sharp, thin, "Tsit" Notes--obviously AlCN's. Eventually the bird flew up into a nearly tree and uttered "chuck" Notes (like those described above, yesterday) as it came into land. The "Tsit" and "Cluck" Notes seemed [[end page]]

[[Left margin of this section has gray hatch lines alongside]] to be quite distinct morphologically, and didn't integrate at all. It is possible that the "Chuck"s contain an appreciable escape component, but this is probably much less than in the "Trit"s. (I.E., the "Chuck"s of this species - and presumably the [[underline]] Throupis [[/underline]] tanagers as well - are produced by slightly different motivations than the rather similar-sounding "Chuck"s of the Red-throated Ant-tanager - see today's notes on [[underline]] Habia.) [[/underline]] [[underline]] Saltator, [[/underline]] I March 27,1958 K-6 [[margin has green hatch lines]] [[green mark]] = Black-headed Saltator = [[underline]] atriceps [[/underline]] Saw one of their birds this morning. Sitting on top of tall bare tree, in the usual erect Saltator posture. Uttering rather thin, high-pitched "Whee hee" Notes. Presumably CN's Also gave a few high-pitched thin Trills (Till) Could these be the equivalent of "song"? They were certainly rather reminiscent of Yellow-faced Grassquits!! [[underline]] Saltator, [[underline]] I March 30, 1958 Bano Colorado [[black and red hatch marks in margin]] I managed to catch 2 Saltators in my nets at K-6, one Streaked and one Buff-throated (both unbanded). I have been keeping them in a small cage, where they have shown a little behavior. When I caught them in the net (and every time I peek
[[circled]] 4 [[/circled]] [[underline]] Saltator [[/underline]] March 3, 1958, II [[red and black pencil marks in margin]] one up in my hands) they fight and behave just like Ant Tanagers Lots of H Ser- apparently indistinguishable from that of the Ant Tanager. I have now seen a little more of the Flicking. WF's are certainly rare in both these Saltators (as compared with many other tanagers) and relatively slight apparently always coordinated with TF's; and the WF movements themselves are merely very slight (straight) upward movements of the (folded) wings, with little or no spreading of the primaries. The TF's are more conspicuous (and perhaps commoner?) Very different in the 2 species (or at least the 2 individuals I have in the cage) The tail of the Streaked seems to be "loosely attached" to the body; it seems to sort of flop around. (It is possible that this birds tail was somewhat damaged during capture- but I am not so sure about this as I once was) Anyhow the TF's of the Streaked are much more conspicuous and extreme than those of the Buff-throat Usually V-D, with quite a pronounced lateral component (But these TF's are certainly less extreme than those of the Sangre de Toros of Blue black Grassquits) The TF's of the Buff-throat are very slight and quick movements , very difficult to see; usually V-D, I think, with little or no lateral component. These 2 captive birds have done quite a little bit of fighting. Brief face to face pecking bouts, when they happen to come too close to one another on a perch. Usually accompanied (preceded or followed) by definite silent G's, apparently the same in both birds. Sometimes, during the longest and/or most obviously violent disputes, also accompanied by a few
[[underline]] Saltator, [[/underline]] Mar. 30, 1958, III [[circled]] 5 [[/circled]] [[red and black pencil lines in margin]] HAC Notes. These sound just like brief, low intensity versions of H Ser. (This is also true of other species of course; and I am now fairly certain that "HAC" and "H Ser" are really intensity extremes of an essentially single pattern) This HAC is also accompanied by pronounced opening of the bill like G This makes it difficult to tell which bird or birds is giving the call, but I am sure that the Streaked has, and I think the Buff-throat has too. It is fairly obvious that the HAC is higher intensity than the silent G in many cases at least. It is also my impression that the HAC may be relatively more aggressive than the G. I think the Streaked, at least, tends to give HAC's when it is pecking at the Buff-throat most vigorously. This captive Streaked seems to give many more sharp CN's (all or most of which are ALCN's) than the captive Buff-throat It doesn't actually appear to be more alarmed than the Buff-throat-which would indicate that its ALCN's appear at lower intensities of motivation than those of the Buff-throat. Neither of these captive birds has a really distinctive pre-flight posture like that of the Sangre de Toro; but they certainly tend to hold the body fairly horizontal (i.e. in a position quite unlike their usual sitting posture) when they want to fly a lot or very frequently. I have twice let both the captive birds loose in the aviary; and each time they have just scuttled off, on foot, into the shrubbery, and stayed skulking . Is this significant? (I think so.)
[[underline]] Saltator, [[/underline]] Mar, 30, 1958, IV [[circled]] 6 [[/circled]] [[red and black pencil lines in margin]] Later this afternoon, after the 2 birds became a little used to the aviary, they emerged and I got a better view of their TF's It turns out that the Buff-throat can perform quite an extreme TF's as the Streaked when it is really highly motivated, [[underline]] i.e. [[/underline]] wants to fly very badly but is also greatly inhibited. Both birds may fan their tails a little, during + between TF's. The usual course of their tails during extreme TF's are also somewhat reminiscent of the [[underline]] Ramphocelus [[/underline]] tanagers [[image-line of arrows, pointing right, placed end on end going in a slightly flattened half circle. Done to show the tail moves from down and to the left, upwards towards the right, and then down and to the right accompanied by the citation: this sort of thing]] Well! No sooner said than done! I have now seen both birds perform still another type of TF Extreme V-D, without any lateral component at all. [[underline]] Saltator , [[/underline]] I April 1, 1958 Barro Colorado The escape or alarm behavior of these birds does really seem to be rather distinctive. They both lurked in the shrubbery almost continuously throughout their first day in the aviary. Then, yesterday, the Streaked emerged, and spent most of its time flying nervously back and forth around the top of the aviary, taking off in alarm every time I made a movement, (i.e. it began to behave like very "nervous" individuals of most of the other species I am studying.) Finally, late today, the Buff-throat emerged and began to fly about nervously like the Streaked.
[[red and black lines in margin]] Saltator, Apr.1, 1958, II [[circled]] 7 [[/circled]] This Streaked is certainly very aggressive Much more so than the Buff-throat. Every time the Buff-throat landed beside the Streaked this afternoon, the latter would turn toward the Buff-throat, lower its head + stretch the neck forward (this looked rather like an unritualized version of the FGfluff of the Pico Gordos or the C of the Sangre de Toros- without any fluffing) and utter HAC Notes (sometimes preceded by momentary G's, and accompanied by jabbing pecking int. movs.) These HAC Notes may have been relatively low intensity Anyhow, they were slightly softer and much less urgent sounding than H Scr Notes. [[underline]] Saltator, [[/underline]] I April 2, 1958 Barro Colorado The Buff-throat had remained outside the ground shrubbery all day, so I guess it is settling down. This bird has also turned out to be quite aggressive Time and again it has pecked at the Yellow-rumped Tanager which it often perches beside. Some of these attacks have been real "pecking bouts"; the Buff-throat standing more or less erect and delivering a real hail of downward pecks upon the poor tanager (who usually retreats fairly soon) The most surprising thing is that [[underline]] all these attacks + aggressive acts have been completely silent! [[/underline]] No sign of H Scr!! (And these are certainly the circumstances in which the Streaked would be uttering many H Scr notes.)
[[red pencil lines in margin]] [[underline]] Saltator [[/underline]], I 8 [[circled in top right corner]] April 6, 1958 Barro Colorado I caught another Buff-throat near K-6 the other day Banded yellow left and let loose in the aviary. The other Buff-throat has been very hostile to the newcomer. Every time the newcomer comes near the old bird flies or rushes toward it in a supplanting attack, and the newcomer retreats immediately. All quite unritualized. No sounds. [[underline]] Saltator [[/underline]], I April 7, 1958 Frijoles An apparent dispute between 2 Buff-throats near here this morning. One bird advancing in short flights, the other retreating the same way. No apparently ritualized postures or movements, but both birds uttering calls which I shall term "Rattle-peeps" (RP) from time to time during the encounter. Each RP divided into 2 parts. First a series of short hard notes (most frequently 3, I think, but sometimes more), followed by a more or less plaintive melodious whistle-like note (also not very long, but much longer than any of the preceding notes) [[three short thick dashes followed by one long, slightly upward-curved dash]] This looked rather like a territorial boundary dispute, as the pursuer eventually turned away and went back in the direction he came from. I wonder if this is a variant of the WS I heard on March 16??? I certainly think so.
[[red and black lines in margin]] [[underlined]] Saltator [[/underlined]], Apr. 7, 1958, II [[circled]] 9 [[/circled]] A single (♂?) Streaked has also been around this morning, singing from bare twigs on the top of tall trees. Song itself is very simple. When complete, it seems to be in 2 parts - like so many vocalizations in this group. First 3 notes, rather sharp, and then a longer, more plaintive and whistle-like note: [[image - two short lines;another short line slightly below the first two; followed by a fourth line which is long, and upward curving. Underneath is written: duh duh duh wheeeooo]] Sometimes abbreviated by dropping out one of the first 3 notes; sometimes cut off without the last note. Given from an erect sitting posture, apparently unritualized. Wings drooped, but not spread. The whole wings lifted out from body a little, sideways, with each note, (apparently just the physical result of forcing out the sound) A few of the notes, including some of the notes of the first part and the last longer note also, were accompanied by a "rattle undertone"; but this was [[underlined]] definitely not [[/underlined]] present in most of the notes most of the time. This would certainly seem to be a WS, strictly comparable and homologous with those of the Buff-throat. This afternoon, back on BCI, I watched the captive Saltators for a little while. Not much - just one interesting fact about the Buff-throats. When I first put the second Buff-throat (yellow left) in the aviary a few days ago, it did [[underlined]] not [[/underlined]] skulk in the underbrush. Flew back and forth very excitedly near the roof; but gradually settled down rather well. But today it does seem to be remaining very low in the bushes. Presumably due to the aggressiveness of the first Buff-throat, which is strongly dominant, and still attacks yellow-left
[[underline]] Saltator [[/underlined]], April 7, 1958, III. [[circled]] 10 [[/circled]] [[red and black vertical lines in margin]] whenever the latter comes too near. Yellow left has only perched on the top branches in the aviary this afternoon when the first bird has been down feeding. I think it is safe to say, as a result of my observations of captive birds and wild ones in several areas, that neither the Streaked nor the Buff-throated Saltators have the slightest trace of gregariousness - at least at the present time. [[underlined]] Saltator [[/underlined]], I April 10, 1958 Frijoles I had a few brief chances to hear WS's by Streakeds near the RR station this evening. Apparently 2 different birds involved. Their WS's quite different. One bird gave a WS comme ca: [[image - two short lines; followed by a longer third line slightly below; followed by a long fourth line slightly above which starts and ends straight with a slight upward curve along the middle; followed by a downsloping wavy line]] Like the WS described on Apr.7, p.9, but the last long note usually followed by a soft rattle. This "rattle" is really the same thing as the "rattle undertone" mentioned above - and in some of the WS's of this bird, it seemed to begin, somehow, before the last long note was finished. (This soft rattle must be produced by some very different mechanism than the pure notes.) This bird gave its WS's repeatedly, again & again, perched by itself, alone in the top of a tree, without apparently inducing any response by any other bird. Finally flew away and disappeared. The WS's which were apparently given by another bird were as follows:

Several times this bird added another doublet to this phrase: -- __ And once it uttered a long very abnormal WS which was almost pure doublets, very roughly comme ca: -- __ -- __ -- __ -- __ more reminiscent of the WS of the Buff-throat described on Mar. 16, p.1 or the WS of the Blue Tanager.

After a burst of WS's, this bird began to utter doublet CN's. Much like those described on Mar. 16, but perhaps thinner, weaker, more whistle-like.
[[underline]] Saltator, [[/underline]] I [[circled]] 12 [[/circled]] April 17, 1958 K-6. [[red and black lines in margin]] I have been struck again + again by how much the "chuck" Notes ( - - - .)[[each note a little shorter and lower than its predecessor]] given by Streaked Saltators flying away from me as they come down to land another perch resemble the regular notes of Palm Tanagers in the same circumstances. Almost identical in fact I have now heard another Streaked sing repeatedly without a trace of rattle or rattle undertone. Several Buff-throats flying about near we have uttered rather thin + weak "Wheet" Notes. Either single, or, when they fly up or off, a brief series (i.e. like some of the tanagers) These birds may have been a little nervous about my presence; so these "Wheet"s may have been either CN's or ALCN's. I think they may at least have been CN's like the "chuck" Notes of the Streakeds (The rhythm was the same when they occurred in series, although the actual sound of the notes themselves was quite different.) [[underline]] Saltator, [[/underline]] I April 28, 1958 Rio Chucunaque There are a number of buff-throats here who occasionally come near me when I am sitting down watching other birds They usually utter the thin weak "Wheet" Notes described above, April 17, with every sign of nervousness, i.e. crouched pre-flight posture and TF's I am now tending to the opinion that these [[underline]] must [[/underline]] be at least a relatively

Some of the birds sometimes seem to utter very similar notes which are just a little sharper; and it is possible that these are even more alarm AlCN's, produced by a relatively even stronger escape drive. One bird near me gave a few soft warbles (!) interspersed among a lot of "Wheet" Notes of the less sharp type!! [[underlined]] Saltator [[/underlined]], I May 2, 1958 Frijoles A single Streaked, sitting on a bare limb at the top of a tree, gave WS after WS this afternoon while I was waiting for the train Each WS was essentially identical with the one outlined on the top of page 11, Apr. 10.

I can confirm that the WS's of the Streaked Saltators here are essentially similar to those of birds near Frijoles. One of the birds here, however, often gives an abbreviated 3-syllable, presumably low intensity version of a WS. like this [[image-line; slightly lower line; long line which slightly slopes upwards]] more or less. This is exactly similar to the brief WS's which my captive Streaked Saltator gives - the only WS's it has ever given in captivity, in fact. It is this tri-syllabic WS which is so reminiscent of the "cho-ub-boh" of the Rose-breasted Thrush Tanager. I noticed that the pair of Streaked Saltators nearest to me always gave a little series of "chuck" notes [[image- a series of six lines each slightly shorter and lower than its predecessor]] Whenever one bird came in to land beside another, or when the 2 birds landed together, Definitely a landing and/or greeting call.

Tends to give his WS's from far more concealed sites than any [[underlined]] Saltator [[\underlined]] I have ever seen in Panama. Well hidden by leaves. (This is probably a real specific or individual difference; but it should be noted that almost all the birds around here are shyer than in Panama.) The WS's themselves are quite distinct from those of the Panamanian forms with which I am familiar; but still quite unmistakably Saltator-like. Usually 4 or 5 short notes followed by a longer one: _ _ _ _ _ _____[[last line slopes upward]] Might be transcribed by something like "Duh duh duh duh duh Wheeeeeoooh."

I was watching one bird sitting high on an exposed perch, preening itself, when its mate flew in. The flying bird started to give rather rapid "Kaa kaa kaa kaa kaa kaa…" or " Kauh kauh kauh kauh…." Notes as it came in, starting at least 5 ft away. The perching bird started to give the same notes. The flying bird landed beside the perching bird; and both continued to give more of the same notes, while they sat almost side by side. Their notes were really rather hoarse in quality. I am almost certain that [[underlined]] they are strictly homologous with the GHAC of the green barbed Sparrow [[/underlined]], and I shall call them by the same name. The sitting birds gave them from absolutely unritualized sitting postures, the bill opening & closing in rhythm with the notes. Then they gradually relaxed, stopped calling, both started to preen, and then they both flew off together. Well! Well! Well! ♀ Saltator lands on perch by herself. Stands there a few seconds, looking rather nervous. Utters an occasional loud, metallic CN-type note. Might be transcribed as "Auh". Then suddenly assumes St Posture with Q. Very extreme. Wings out and partly drooped during the Q. Head & bill nearly vertical. Tail diagonally raised to a very extreme degree. Probably not spread to any great extent. Breast lowered very far. Breast & especially belly feathers very [[underlined]] very [[/underlined]] ruffled. Tail apparently not quivered at all.

He immediately mounted the ♀, without any preliminary display. The copulation was very brief and apparently unsuccessful the ♀ continued St.+ Q throughout, I think; but the ♂ slipped off immediately and flew at least several ft. away.

Also another pair well-mated, but apparently no nest yet. This species is quite shy here, in the sense that it tends to fly away quite promptly when one approaches. But most of the birds seem quite stolid otherwise, sitting all but motionless for long periods of time when un-alarmed. Presumably correlated with this comparative lack of mobility is the fact that it utters remarkably few CN’s. I have only heard one bird utter about 5 or 6 CN’s, single notes at quite long intervals, given by a ♂, after WS-ing, before flying off. These CN’s are not unlike those of the [[underlined]]Rhamphocelus [[correct spelling, Ramphocelus]][[/underline]] tanagers here, but even more metallic, i.e. even more like the CN’s of the Blue-black Grosbeak (although apparently never double) The ♂ gives his WS’s from much the same posture as the other Saltators. Sitting very erect. In some cases, at least, he also tends to point the head & bill diagonally upward, to some extent, at an angle approximately like this [[arrow at 2 o’clock position]] I am now fairly certain that mates tend to give GHAC whenever they join one another I even heard 2 birds give repeated bursts of GHAC when they were just sitting (and/or moving about very slightly) in the same tree only a few feet apart. Unfortunately, however, I never got a good view of the birds doing this, this morning, so I don’t know if it is usually accompanied by particular movements or postures or not. One juvenile sitting near an adult this morning reacted to the adult in a rather peculiar way which may have been begging. From time to time, especially when the adult turned toward it, it would open its bill and utter a [[ZZ or 33?]] call This [[ZZ or 33?]] consisted of a [[end page]]

Blue hatch marks=Greyish (coerulescens) see Transcription pg60/pg15 Dec 14 1958]] Watching a pair of these Gray Saltators moving around from tree to tree together Did lots of mutual displaying. Coming into a perch, the in the lead would usually give about 3 CN's as it landed. Then would stand a second until the second bird landed beside it. Then both would do a burst of GHAC. In apparently unritualized posture sitting erect as usual, head & bill apparently inclined obliquely upward a little. (They also did a lot of nervous-looking side-to-side turning of the head during this, but these movements might have been provoked by my presence.) Then they would sit quietly near (about 6" apart) one another for a second or so; then, still sitting together, they would do another burst of mutual display, GHAC (and CN's-see below); fall silent again; then do another burst of mutual display, GHAC etc., while they still sat together; then fall silent again; etc. etc. etc; until finally one bird would fly off to another perch, the second would follow, and the whole process would be repeated again. During some of these bouts of what I presume were mutual GHAC one or both birds uttered a few CN's of the usual metallic type. It is even

It is apparent now that this species uses its GHAC even more frequently than the Green-Barbed Sparrow. Not only a greeting but a display when the mates are more or less stationary together. I am sure that the stationary Green Barbed Sparrows do GHAC much less frequently. One of the birds during some of there mutual display performances (presumably the ♂) uttered a few abbreviated WS phrases, between the GHAC-CN performances, in spite of the fact that its mate was present! One of the birds has perched in a tree near me and adopted a most extreme, apparently pre-flight, posture, with drooping wings. [[bird drawing of what was described in the last sentence.captions: Looking long + slim with tail frequently slightly raised.]] The ♂'s of this species seem to have another WS pattern in addition to the one I have described before. Soft, and difficult to determine exactly who is doing it and where it is coming from; but it tends to occur in association with the ordinary WS (which I shall call LWS, from now on), although [[many?]] LWS's occur without it; and I think that it is usually given by ♂'s when their ♀'s are not too far away. Might be transcribed as "Duh duh [[wavy underline]] whirrrrrrr[[wavy underline]]" Apparently given from the usual unritualized sitting posture. This "whirrrrrr" is obviously related to the [[horizontal line over wavy line]] notes of the Saltators at BCI.
[[Underlined]]Saltator[[Underlined]], Dec.23,1958,III [[circled]] 21 [[/circled]] [[blue vertical lines in margin]] I shall call this type of WS the "SWS", as it is relatively soft. The "Whirrrrrr" is much softer than the "Wheeeoooo" of the ordinary LWS, to which it is probably closely related; and even the preliminary, "duh"s are probably softer than those of the LWS. The SWS may well be very low intensity and/or greatly inhibited version of the LWS. In this connection, I should mention that what appear to by very low intensity ordinary LWS's the initial LWS's long before sunrise, also include only 2 preliminary notes, comme ca: [[two short lines followed by one longer line]] [[underlined]] Saltator [[/underlined]] I. December 24,1958 Iquitos The [[male symbol♂]] gray Saltator that I have been watching for a few days seems to have another type of LWS in addition to the one I have described before "Duh Wheeeeoooo Wheeeeoooo duh duh wheeoo" comme ca: [[dash,two long upslanting curves, two dashes, wavering line]] Given by [[male symbol♂]] separated from [[female symbol♀]], in usual sitting posture, bill OCB with notes, frequently associated with "ordinary" LWS. The [[male symbol♂]] also gave a few brief phrases intermediate between this "special" LWS and the ordinary type; and the most common variation of this special type itself was the omission of the last note. I think that the unmated [[male symbol♂]] I watched last week also gave "special" LWS's of this type. This [[male symbol♂]]'s "singing posture" is [[underlined]] quite [[underlined]] long-necked. Neck feathers quite ruffled during the notes. Lower body feathers somewhat fluffed

I have now seen more "mutual displaying" between mates, more or less like yesterday. The [[female symbol♀]] landed in a tree, and the [[male symbol♂]] eventually joined her. They both did GHAC as and after he came in to land. Then sat side by side for a second, in normal sitting postures. Then the [[male symbol♂]] began LWS, the [[female symbol♀]] immediately started GHAC, the [[male symbol♂]] immediately stopped LWS and began to do GHAC too, they did GHAC together for a second, then shut up and sat silent for a few seconds. Then the [[male symbol♂]] began LWS again, the [[female symbol♀]] began GHAC before he had finished the third note of the LWS, he stopped LWS and continued GHAC, they both did GHAC for a couple of seconds, then shut up. This whole procedure was repeated at least 5 times. This behavior would certainly suggest that the [[female symbol♀]] "uses" GHAC to suppress song (and/or cop. attempts?) by the [[male symbol♂]]. This would suggest that the GHAC contains a hostile component - as its actual sound would certainly suggest also. (But I must add that I have never seen the birds make attack [[int. moves?]] during GHAC. Except during the one copulation attempt I saw, they have just sat, usually looking toward or facing one another, in apparently quite unritualized sitting postures.)
[[underline]] Saltator, [[/underline]] I. [[circled]] 23 [[/circled]] December 30, 1958 Frijoles [[pencil lines in margin]] Watching a pair of Streaked Saltators here. One bird flying about from tree to tree. Each time it came in to land, it uttered a series of notes. These are obviously what I have been calling "Chuck" Notes earlier (e.g. Apr. 17, p.12) , or, at least, closely related to them; but I noticed today that they are rather "hoarse." They sound, in fact, very much like the GHAC of the Gray Saltators. The notes of the Streaked, however, seem to be somewhat sharper-sounding; and with somewhat longer pauses between notes. The notes of this Streaked Saltator this morning seemed to be exactly intermediate, in form, between the GHAC of the Gray Saltators at Iquitos and the usual "landing CN's" of the [[underline]] Thraupis [[/underline]] tangers!!! (This would suggest that the "GHAC" is more closely related, phylogenetically, to the CN's of tanagers than to the HAC + HScr patterns of tanagers.) The bird today gave its "Chuck" GHAC Note (which I shall call just GHAC from now on) both when it landed near another bird which I presumed was its mate and when it landed some distance away, (although the other was always present, I think, in the general area- say within 20 or 30 ft.) It is possible that the mate responded by giving GHAC in return, when the first bird landed near it; but I am not sure about this. The only others sounds uttered by these 2 birds were a few single "Tsit" CN's, quite like those of the Gray Saltators at Iquitos, although probably less metallic. I saw no reason to believe
[[underlined]] Saltator [[/underlined]], Dec. 30, 1958, I. [[circled]] 24 [[/circled]] [[vertical black lines in margin]] that these were particularly alarm reactions (S. Mar. 17, p.2) [[underlined]] Saltator [[/underlined]], I June 30, 1959 Rio Piedras [[green vertical lines in margin]] I watched a pair of Black-headed Saltators moving through the trees near second growth near the river here. Probably feeding. Very very loud & noisy. Constant call notes and/or alarm notes (possibly provoked by me). These notes were extremely variable, ranging from high-pitched & rather penetrating "Trit"s to very harsh"Chauk"s. Also some metallic bell-like notes, quite like some notes of the Streaked Flycatcher and the Blue-black Grosbeak. These notes usually uttered as single notes, occasionally double. (Double notes of the metallic bell-like type were particularly reminiscent of the Blue-black Grosbeak.) Bill usually opened & closed with each note, but apparently no other ritualized postures or movements. Every time one of the birds landed near the other, they both performed GHAC made up of about 6 hoarse, harsh, "Chauk" or "Kauk"-like notes perhaps with an "R undertone". Very rapid but rather irregular in rhythm. Almost certainly more irregular than the GHAC of the Streaked Saltator and probably more irregular than the GHAC of the Gray Saltator. Perhaps comme ca: [[wavy line representing bird call]] Often ending on a relatively prolonged rising note, which sometimes, but not always, became clearer & more whistle-like in quality. The GHAC was uttered from an ordinary unritualized sitting posture. Bill open, with mandibles moving in rhythm with the call. [[red vertical lines with two question marks in margin]] Later on this morning, I heard some most peculiar calls uttered by a bird which was probably a Buff-throat. The bird definitely had a buffy throat

Possibly provoked by and directed toward me. Some of these calls might be transcribed as "Tsiwit tsiwew". while others were preceded by one or two introductory notes. "Tit tit tsiwit tsiwew". All most peculiar! [[underline]] Saltator, [[/underline]] I. July 1, 1959 Rio Piedras Back at the same place today. Watching another Buff-throat. Sitting alone, high in tree, over second growth. Doing a lot of preening, interspersed with song-like soft warbling phrases. Obviously homologous with the call described immediately above; but slightly different in form. I think this difference in form was purely an individual difference- as the bird performing today was almost certainly different from the one I watched yesterday Most of today's calls might be transcribed by something like "Jit tsit tsewewhoowoo." I think I shall call all such phrases (including calls such as the one I heard yesterday, "Wbl"s. Wbl's are certainly quite different from the WS's in form- and also [[underline]] much [[/underline]] softer. The bird givng Wbl's this morning certainly gave some of them when there were no other Saltator's audible in the neighborhood; but it also gave a lot apparently as response to WS's coming from several yards away. (I couldn't see the bird giving WS's; but the WS's themselves were quit typical of either the Buff-throat or the Streaked, and I presume that they were being uttered by the mate of the bird giving the Wbl's) The bird giving the Wbl's apparently started every Wbl after the other
[[underline]] Saltator, [[/underline]] July 1, 1959, II. [[circled]] 26 [[/circled]] [[red and green pencil lines in margin]] bird had started the WS, and then continued the Wbl a few seconds after the other bird had stopped the WS. The ratio of Wbl's to WS's was obviously 1 to 1 in such circumstances- 1 Wbl answering a single WS I also watched the same pair of Black-capsar yesterday. Behaving in much the same way as yesterday. Lots + lots of CN-like notes whenever disturbed by me (but usually quite silent otherwise). I think I shall have to give the different types of these notes different names. I shall call the harsh "Chank"-like notes "CHN"; and the high pitched "Tsit" note TSN. I think that the particularly bell-like, Blue-black Grosbeak-like notes may be nothing more than variants of the TSN. It is my impression that both birds occasionally gave all types of these notes; but certainly for a long time one bird consistently gave CHN's while the other consistently gave TSN's. Possibly a sexual difference??? I wonder if this two type of "CN" arrangement is homologous or analogous with the similar division of CN's in [[underline]] Rhamphocelus [[correct spelling, Rhamphocelus]] [[/underline]] tanagers? Both birds also gave a lot of GHAC today. Again much as yesterday. But I noticed that a bird often uttered GHAC when it landed by itself, at least several feet from its mate, as well as when landing just beside the mate. I.E. the GHAC of this species is uttered in very much the same way as that of the Streaked (see Dec. 30, 1958, p.23). There is undoubtedly considerable variation in the GHAC's of the Black caps. One bird today uttered quite a lot of GHAC's, quite close together, which might be transcribed as "Tsit tsit tchantchantchantchanh" [[two far spaced lines followed by a series of four, close, descending lines]] This appeared to be eventually composed of 2 TSN's followed by an accelerated series of 4 CHN's. The bird uttered these when it was sitting more
[[underline]] Saltator, [[/underline]] July 1, 1959, III [[circled]] 27 [[/circled]] [[green pencil marks in margin]] or less apart (several feet away) from its mate. The whole performance looked very much like "song". Once when one bird landed close beside the other, the latter briefly assumed a posture which may have been a weak nit. mov. of ft. Quite silent. [[underline]] Saltator, [[/underline]] I July 7, 1959 Frijoles I found a pair of Black-caps here too, with a nest, with at least one young (probably half grown, as far as I could tell from a distance) in it. In general the birds behaved much like the birds I have seen at the Rio Piedras. Lots of TSN's CHN's, and GHAC's. When I came particularly close to the nest, the only parent that was around at the time uttered lots of single CHN's, and very few TSN. Might suggest that the CHN's are relatively high intensity. One bird was heard to utter double notes, 1 CHN - 1 TSN, comme ca. __ -- __ -- __ -- When I wasn't very close to the nest. So it is definite that these 2 types of "CN" are not strictly segregated according to sex. I also wonder if these double notes are related to the double notes in the WS's of the Streaked + Buff-throated Saltators, and some of the introductory notes to the songs of the Green-backed Sparrow. One of the Black-throats sat alone in a tree for several seconds, when I was far away from the nest; and uttered at least 3 bursts of "GHAC". Sounded quite like the GHAC's I have heard before. The bird just sat still while it uttered these phrases. Such facts might suggest
[[underline]] Saltator, [[/underline]] July 7, 1959, II. [[circled]] 28 [[/circled]] [[black pencil marks in margin]] that this species has lost (or is losing) a song pattern like the "WS" of the other Saltators (see below), and that it was its GHAC as a "substitute" for the "WS"'s of the other species. I also watched some Streaked Saltators this morning, apparently unmated males, doing a lot of singing while separated from their mates. Much as before I did notice, however, that sometimes especially early in the morning, a bird would utter a nearly "random" jumble of "WS" notes, high + low notes not uttered in regular alternation like the note of typical WS's Sometimes reminiscent of the short jumble-like notes of Green-backed Sparrows early in the morning. (see today's notes on [[underline]] Arremon [[underline/]] ) One Streaked certainly, uttered a complete GHAC, once, when landing in a tree by itself, when the mate was apparently not in the neighborhood. [[green, red, blue, black pencil marks in margin]] So far, it would seem that the Streaked and the Gray Saltators are more or less intermediate between the Black-capped Saltator and the Buff-throated Saltator in behavior. [[green, red, black pencil marks in margin]] One thing I have noticed both here and at the Rio Piedras is that the these local species seem to overlap extensively without any indication of hostility between any of them. This morning, the same perch, at the top of a tall tree, was used alternately, by a Streaked Saltator (who gave WS’s there) and a Black-capped Saltator (who gave GHAC’s and/or “CN”s there). The Streaked Saltators here do not seem to be birds of the low undergrowth like the Streakeds described by Skutch. They usually or always give their WS’s from perches quite high in trees, at least 20 ft above the ground, and sometimes considerably higher. (It may be significant, incident [[end page]]

At the Rio Piedras, the only species I have seen really high in tall trees (70ft or more) is the Buff-throat. Both the Black-cap & Streaked seem to stay lower (at heights of approximately 12 to 30 or 40ft), at least most of the time. The Streaked is the only species I have seen in very "open" second growth, in bushes & trees on the edge of pastures; but it also occurs quite frequently in the thicker second-growth where I have been watching the Black-caps. I think I shall drop the term "WS" as applied to Saltators, and just use the term "song" tout court. [[Underlined]] Saltator [[/Underline]], I. April 12, 1960 Porto Bello Black-capped Saltators are by far the commonest species of Saltator in the neighborhood here. We saw at least 3 pairs of Black-caps here in the first half mile or so of the Las Cruces Trail. (The only other species of Saltator I think I have seen here is the Buff-throat. I may have seen one or two apparently single Buff-throats around; but I cannot be sure of this.) The Black Caps were very noisy and conspicuous; and may well have been beginning the breeding season. I think that I understand the song & related patterns of this species a little better now. We came upon one pair around 7:00 a.m., which appeared to be engaged in a territorial dispute.

In a posture comme ca:[[image-drawing of a bird calling]][[notation to the left of drawing, All the songs this bird uttered during the dispute were eventually identical in form.]][[notation to the right of drawing, Bill up, head small, neck elongated.]] All the songs began with a single long, high pitched and/or rising note; which might be transcribed by something like "Tseeeeeeeeee" or "Wheeeeeeeet".

Presumably just a type of HAC in these circumstances. Some of these HAC Notes might be transcribed by something like "Chuk-a" -- although this probably greatly exaggerates the bisyllabic division (which was never more than slightly indicated). I think that the series of HAC notes following the initial "Freeeeeeeeeeee" or "Wheeeeeeeeeet" Note usually included 5 or 6 notes. These series of HAC Notes were always or almost always followed by a single "Freeeeeeeeeee" or Wheeeeeeeet" Note exactly like the one that introduced the performance. This last "Freeeeeeeeeee"

There was always a pause after these last notes (before the beginning of a new song phrase). All the song phrases during this dispute might be represented by the following diagram. [[image-line sloping upwards, underneath is written "Freeeeeeeeee"; next are five short waving lines underneath each is written, HAC; next is a line sloping upwards, underneath is written "Feeeeeeeeeee". I shall call these "Feeeeeeeeeee" or "Wheeeeeeeeeet" introductory and terminal notes "Seee" Notes; and the HAC Notes during song phrases "SHAC". After a few minutes, this dispute apparently died down. I think the intruder(s) must have left. After this, we could no longer see the birds well; but one bird (presumably the ♂ of the victorious pair) uttered song phrase after song phrase, at few sound intervals. These song phrases were rather different from those uttered during the heat of the preceding dispute. They always began with what might be called an "introductory" phrase of 3 or 4 notes. (I shall abbreviate this term to "Intro" throughout the following pages.) Many of these song phrases were preceded by a few single CHN's. The first note of the Intro phrase of the songs was also a CHN, apparently identical with the ordinary single CHN's. This was followed [[underlined]]immediately[[underlined]] by a Seeeeeee Note. quite like the Seeeeeeee Notes during the dispute described above.

This might be transcribed by something like "Fee-tee tee tee tee-yoo" [[four lines are written underneath with the fifth slightly lowered and angled down.]] No other cases, the Intro was followed by a few SHAC Notes and then the warbling phrase as above. (I shall abbreviate the warbling phrase as "Wbl".) Both types of songs, those with both SHAC + Wbl and those with Wbl but without SHAC, usually ended with another Intro, just like the preliminary one. Thus a song phrase with Wbl alone might be represented by the following diagram. [[ there is a short line, followed by a long upsloping line, a line slightly lower than the first, and another lower then both, four lines at the same height as the first the fifth slightly below the four and at a slight downward angle, a line exactly like the first, a long upsloping line a short line at the same height as the third line, and a line slightly lower, the same height as the fourth line. under each respective line are the following "words" CHN, Seeee, "Ta-tub", Wbl, CHN, Seeeee, "Ta-tub". I only caught one glimpse of the bird while it was uttering there songs. It appeared to be uttering alone, probably in the same posture as drawn above on p. 30. I think that these songs must have been less strongly hostile than the songs with SHAC but no Wbl during the preceding dispute. It also seems likely that the songs with both SHAC and Wbl are more strongly hostile and/or more aggressive than the songs with Wbl but no SHAC. Some of these songs after the dispute may have been "triumph" songs-what ever that may mean. Later on we came across another pair. Obviously disturbed by our presence, but reluctant to leave the neighborhood. Presumably strongly territorial. One or both birds kept flying away, and then returning to the same tree near us. They may have had a nest there. In any case, as a result of all this flying back&forth, the mat

One bird (the ♀?) uttered single CHN's when separated from its mate. What I presume was another bird (the ♂?) uttered bursts of 2 or 3 notes which appeared to be partial or complete Intros, without any other song elements, in similar circumstances. [[There is a diagram below this as follows: short thick line, underneath CHN; long upsloping line underneath, Seeeeee; short thin line placed lower than first line, underneath "Tub"; or; short thick line, underneath CHN; long upsloping line, underneath Seeeeee]] When these 2 birds were together one or both of them uttered more "complete" song patterns.

Some were certainly hostile and provoked by our behavior. Every time I made a vigorous movement one or both of the birds responded by uttering one or more of these songs.

I couldn't see its mate at the same time, so I don't know what provoked the posture. In any case, the performing bird stayed in this posture for quite a long time, perhaps a minute or so, [[underlined]] without uttering a sound [[underlined]], and then flew off.

All these performances by Yellow were [[underlined]]very[[underlined]] reminiscent of the "Keeyoo" singing of my captive A ♂ Sangre de Toro. This, "Whew" singing (as I shall call it) must, I think be strictly homologous with the "Keeyoo" singing of the Sangre de Toro. These "Whew" and "Whee-ee-oo" Notes are certainly quite different from "Wheet" CN's (see below) but they may be closely related to, or even identical with some terminal parts of some Wbls's (see below). I think that they are fairly distinct from the See Notes of the Black Cap, and (almost certainly) the See Notes of this species (at least the introductory See Notes of the Buff-throat described above on Apr. 21, 1960, p. 35) Every once in a while Yellow would interrupt his "Whew" singing to utter a brief, not very loud Wbl. Some of their Wbl's included 5 notes, while others included 3 notes. "Tsit tsit tsee wee yoo" and "Tsit Tsee yoo" (Yellow may well have utter 4 note Wbls's too, but I didn't actually distinguish any of this type). These Wbl's were not introduced or followed by any [[dutiuctive?]] See Notes or whistles or anything else. I think they were accompanied by the same posture as the Whew "singing; and they did not appear o provoke any response from the unbanded bird. I imagine that the "Whew" singing may well be provoked by some frustration or thwarting of some pairing or sexual drive, but the Wbl's may be largely or completely hostile (see below). After lunch, I put 2 new birds in the same cage with yellow and the unbanded bird. One of these new birds was banded red, and the other was banded blue. These 2 new birds had been kept together in a small cage inside the animal house for a month or so. The introduction of Red+Blue provoked a lot of hostility from

It looked almost as if the bird had a "false wing". This FG Hff posture (as I shall call it in this species also) was quite silent, and was not accompanied by any G. It was combined with quite a lot of regular pivoting, which appeared to be unritualized and also some irregular "bowing". This bowing was considerably less frequent than the pivoting, and appeared to be equally unritualized-as such. In some cases, it was obvious, however, that the posture at the top of the up-phase was itself extremely ritualized. I shall call this ritualized posture StGHff. It is obviously a combination of the same GHff as in the FGHff with an "ordinary", not very exaggerated, "therapeutic" St Posture. It was also silent, and not accompanied by any large trace of G. It is drawn on the next page.

Small-headed in appearance Notice "Frontal Shield" (The way in which the white eyebrows are so conspicuous in these GHff postures-it is possible that the white feathers are even raised-while the back crown is also covered or hidden-is very reminiscent of the display of the yellow forehead feathers, and the hiding of the dark cover feathers in the GHff patterns of the [[Rio Gordo?]].) While the Yellow ♂ was performing these patterns; he faced the Red newcomer almost directly.When the Yellow ♂ began to perform supplanting attack after supplanting attack upon Red, trying to peck Red whenever he got close enough, and succeeding not infrequently. Red tried to escape without any defense in most cases. Every once in a while Yellow would interrupt his attacks to perform more GHff patterns. Usually ftGHff, with little or no "bowing" and/or FGHff. Some of his ftGHff's in the intervals of attacking may have been were more extreme than the ftGHff's before Yellow began to attack. (Actually, any drawings of the ftGHff is primarily based upon postures between attacks). Both birds were silent durring almost all this attacking + escaping. I did, however, hear one "Whew" Note and one brief Wbl in the middle of the excitement. Probably uttered by Yellow. The rarity of "Wh

One or both birds occasionally uttered a single "Wheet" CN during this attacking and escaping. Some of these "Wheet"s were certainly uttered by Yellow; but it is also possible that a few were uttered by Red. I could not determine if these "Wheet"s were hostile or purely "locomotory". Once (unfortunately when I wasn't looking) one bird uttered a series of 2 or 3 hoarse "Whaul" Notes-obviously HAC or something closely related to it. After a while, Red obviously became very tired. Yellow also began to pause a little more frequently between attacks. Then Red sat in a "submissive" fuffled posture whenever Yellow wasn't attacking. [[image-drawing of bird in submissive posture, red arrows point to areas refereed to in the captions.]] [[captions accompanying image- Submissive Ruffle+G; Back smooth; Notice CR (possibly slightly exaggerated in this drawing); Belly feathers even more strongly ruffled than breast feathers]] (It is interesting that this species does CR when escape is obviously predominant over attack).

This seemed to be effective as threat as it caused Yellow to retreat himself, temporarily. And from this one encounter, Red kept his bill closed all

Finally, after a particularly vigorous attack by Yellow, Red dropped to the ground and crouched motionless under a [[bail?]]! Yellow remained sitting on a high perch after Red dropped, and then uttered 3 or 4 Wbl's, one right after the other "Triumph Song" (like the "triumph song" of the Black-Cap described above on Apr. 12, p.32) Possibly due to a sudden relative decrease in the strength of Yellow's escape drive, and relative increase in the strength of his attack drive, due to Red's sudden disappearance from sight??? In any case, Yellow did not make any attempt to approach either of the other birds in the cage after his Wbl's. I then took Red out of the cage, as it was beginning to look much worse for wear. After Yellow settled down again when I left the cage, it just sat in a rather sleek, alert-looking (pre-flight") posture, for a few seconds. Then he performed quite alot of BW movements. Displacement???? Then he performed a few not very energetic supplanting attacks upon Blue, whom he had completely ignored before then. None of these supplanting attacks upon Blue was accompanied by any display of any sort. This would indicate that Yellow distinguished between Red +Blue in some way. I think that Red must be ♂ and Blue ♀, and that Yellow could distinguish their sexes by their appearance. I stopped observation at this point, as I thought that the birds were slightly nervous about my presence.
[[circled]] 42 [[/circled]] [[underline]] Saltator , [[/underline]] I May 9, 1960 Frijoles [[pencil lines along length of margin]] Watching a single, presumably ♂, Streaked Saltator "singing" here. In usual erect posture; with tail-down. These songs seemed to be more or less typical of the most common forms of song of this species. Relatively slow, with relatively larger notes than any of the Wbls of other species, with which it may be more or less completely homologous The complete songs of this bird might be transcribed as follows [[images of 3 dashes, a large space between the first and second, second and third are placed lower then the preceding lines; diagonal line, squiggly line; underneath is written: " duh duh-duh wheeeeooooo [[wavy line]]]]" I am not absolutely certain that the diagram of the 4th note, which is relatively long and whistle-like is really correct. It is possible that the pitch is descending in all or most 4th notes. [[downsloping line]] It is also possible that there is considerable variation in the 4th notes from time to time. It is possible that some are ascending while others are descending. This is obviously the same thing I called "WS" in my earlier notes on the Streaked (e.g. Apr. 7, 1958, p.9; and Apr. 10, 1958, pp 10 and 11). I am sure that this must be closely related to the songs of other species of Saltator; but the exact details of the relationship are still obscure. It is conceivable that the whole "complete" song of the Streaked; such as sung by the ♂ I watched today, is strictly homologous with the Wbl of the Buff-throat More probably, it is strictly homologous with the whole "WS" of the [[Greyish?]], and the Wbl + See Notes of the Buff-throat and the Black Cap.

These were all [[image-3 descending dashes and an ascending diagonal line]] or [[image-3 descending dashes and descending diagonal line]] [[underline]] Saltator, [[/underline]] I March 28, 1961 Frijoles Watching some birds in the Frijoles are this morning. From appr. 6:15 a.m. to approximately 8:00 a.m. I watched one Streaked (presumably ♂) uttering by itself in the top of a tree singing a rather distinctive "song" for at least 15 minutes, almost without interruption. A series of clear, whistled "Kew" Notes, occasionally interrupted (at irregular intervals) by a single higher pitched, slightly rattling "Kree" Note Comme ca: "Kew kew kew kew kew kree kew kew kew kew kree kew kew kew kew kew kew kew kree..." __ __ __ __ __ __[[wavy line beneath]] __ __ __ __ __ [[wavy line beneath]] __ __ __ __ __ __ __ __ [[wavy line beneath]] . . . . . . The bird sat in the usual unritualized singing posture while uttering these notes. The bird was uttering these notes when I arrived, but stopped when full daylight arrived. This would definitely appear to be a form of "dawn song".
[[underline]] Saltator, [[/underline]] Mar. 28, 1961, II [[circled]] 44 [[/circled]] [[black and red pencil lines along length of margin]] The whole performance was quite remarkably reminiscent of the "Keeyoo" song of the Sangre de Toro and the "Whew" singing of Buff-throated Saltators. The fact that all these performances are essentially "dawn songs" would suggest that they are all high intensity. I heard a number of "songs" uttered by solitary Buff-throats at various times this morning. All well after daylight (long after the "Kew" song of the Streaked described above. All these songs were largely or completely Wbl's. Some might be transcribed as "Jut tsa whee whee." Others might be transcribed as "Tsit tsa-ha-whee" All rather twittering. Uttered from apparently unritualized uttering postures. Sometimes, I think, there were 2 "Tsit" Notes at the beginning of these Wbl's. The single "Tsit" Notes ( and possibly the double "Tsit's") at the beginning of these Wbl's were quite sharp and thin and rather plaintive. Rising in tone [[diagonal line]] Such notes may be more or less closely related to the "Wheet" Notes I have heard uttered by Buff-throats before, apart from Wbl's-see, for instance, my notes of April 28, 1958, p. 12. I saw one bird sitting by itself in the top of a tall tree this morning which uttered lots of single "Tsit"s without Wbl's. These "Tsit"s may be largely or completely homologous with the SN's of Palm and Blue Tanagers and the PCN's of Sangre de Toros. (I doubt if either the "Tsit"'s and/or "Wheet"s are alarm notes) I think that the "Tsit"s which were associated with or in the Wbl's of the Buff-throats this morning may not have been "integral" parts of the Wbl's (in the same sense as the succeeding 3-note phrases or 3-syllable notes) It is obvious that the "Rattle-preps" of Buff-throat described

[[circled]] 46 [[/circled]] [[vertical pencil lines along length of margin]] can be represented by the following diagrams [[image of 2 dashes and diagonal line]] and [[image of 2 dashes and diagonal line]] (I am now fairly certain that the long notes, the whistles, are descending in pitch.) (I have also come to the conclusion that such song patterns are rather similar to certain songs of [[underlined]] Atlapetes [[/underlined]] spp.) I wonder if these "incomplete" songs are partly or wholly homologous with the Wbl's of other species of Saltators???? The Streaked which sang this morning usually sang from a posture like the one drawn on the preceding page. Crown feathers smooth. Head tilted upward. Neck [[underlined]] not [[/underlined]] very elongated. The drawing on the preceding page is a much better drawing than the one shown in my notes of April 10, 1958, p.11. The only variability in this singing posture involved the position of the wings and tail. I think that the wings and tail were sometimes held as in the drawing on p. 11. The bird always sat still while singing. Between song phrases it hopped from bush to bush and tree to tree. It uttered loud, hoarse, harsh notes when it moved. Usually in series of 3 or 4 notes. These were probably GHAC. Possibly HAC. One of the captive birds in the cage frequently uttered similar notes while the free bird sang.

A Streaked Saltator flew to a high exposed perch soon after I arrived, and began "Kew" Song. Probably the same bird I observed uttering "Kew" Song on March 28, 1961. Singing in same place. The posture in which the bird was uttering "Kew" Song today was comme ca: [[image - pencil drawing of bird in center of page]] [[left of image]] I think that the white eyebrows were raised, like the yellow eye brows of the Yellow-faced Grassquit.

A typical bit of "Kew" singing by the bird this morning might be represented by the following diagram: -- __ -- __ [[one line placed high above the others]] __ -- __ -- [[Each of the lowest lines have a wavy line beneath them.]] Every once in a while, the bird would utter 2 clear notes, usually or always one of relatively low pitch and then one of relatively high pitch, in the middle of the song. Comme ca: -- __ --[[one line placed high above the others]] __ -- __ -- __ [[Each of the lowest lines have a wavy line beneath them.]] The bird continued "Kew" singing for almost an hour, with only 2 or 3 brief interruptions. These interruptions occurred when it changed perches. (It did not utter song in flight) Alternated between 2 trees (The same time in which it gave "Kew" Songs on March 28) Always perched high in an exposed position when it gave "Kew" Song. None of the "Kew" Singing provoked any response from any other Streaked. When I first arrived , while it was still rather obscure, before this Streaked began "Kew" Singing.

All this might suggest that "Kew" Singing and "Incomplete" Singing are produced by the same type of motivation; and that the "Kew" is higher intensity than the "Incomplete". All the "Incomplete" Songs of the Streaked this morning were the usual type. [[image-diagram shows the following: straight line; short line lower; another short line lower; high placed line which curves down; wavy line at height of first line.]] [[Hatch marks indicating the following species are along the left side.

April 4,1961 [[Barro Colorado]] I have had 2 Buff-throats in a cage with lots of other tanagers and finches for a long time. Always very dull. Then this morning I noticed that they were disputing with one another. A very long-sustained dispute. One bird chasing the other from perch to perch, almost without interruption, for at least 15-20 minutes. The beginning of the Breeding season? Both birds seemed to have CR throughout the whole performance. One or both birds uttered a lot of "songs" throughout this dispute
[[Underlined]]Saltator[[Underlined]], Apr 4,1961,II [[upper right corner, 50]] [[dispu]]te these "songs" were quite variable. Some of the "songs" appeared to be typical Wbl's. Such typical Wbl's were only uttered when there was a momentary lull in the dispute. Apparently lower intensity than the other "songs" uttered during the dispute. When the dispute was most vigorous, two slightly different types of "song" were uttered. One was a pure Rattle, followed immediately by a typical Wbl. (the Wbl appearing to be a sort of "terminal flourish" to the R). More or less comme ca: [[image-long wavy line; short wave;line that does one wave then curves up.]] The other type of "song" was similar except that the terminal Wbl had a definite rattling quality or undertone (sometimes almost as strong as the pure R) (This combination of Wbl+R may be reminiscent of the Yellow-rumped tanager.) I know that the more aggressive of the 2 birds uttered all 3 types of "song". I am not sure if the less aggressive bird uttered any. After a while, the less aggressive bird appeared to become tired, and occasionally let the more aggressive bird land close beside it without flying away. The more aggressive bird would then go into a rather unritualized "Forward" Posture and peck at the less aggressive bird. This "Forward" posture was very much like the FGHff drawn on May 6, 1960,p.38., except that the breast+belly feathers were less fluffed and (probably)there was a slight trace of CR. Always silent. The less aggressive bird always flew away immediately after being pecked. Both birds sometimes did a little regular unritualized looking, pivoting, and bowing, usually silently, when they were perched not too far from one another.

Usually or always, I think, when the birds were flying. But I couldn't determine who uttered them or why. There were no real FGHff or ftGHff or Submissive Ruffle+G patterns during the dispute this morning.

All the birds seem to utter lots of harsh "GHAC"s, both in flight and when landing next to one another. This morning, around 8:00 a.m., I saw one of these Streaked Saltators land near the other two. It uttered "GHAC"s as it landed. One of the other birds [[underlined]]immediately[[underlined]] flew straight to the newcomer, uttering "GHAC"s as it did so.

Then the bottom bird, presumably the ♀, flew away and the other bird followed. One or both birds uttered more "GHAC"s as they flew away. If this was a cop. attempt (as I think it must have been), it was obviously unsuccessful. I think the "GHAC" Notes uttered by these birds might be transcribed as "[[above each of the a's there is a line.]]cha-ah Cha-ah Cha-ah.....". Quite [[underlined]]remarkably[[underlined]] harsh-much more so than the GHAC's of green-backs.

Red seems to be a ♂. He was uttering "dawn song" this morning when I first began to watch the birds. Usual form Several disputes between 2 birds (can't identify the birds). With silent G's. Once a bird did G & CR. Another time a bird did G definitely without CR. One bird did a lot of "dawn singing" around 6:15 a.m. I couldn't tell if the bird if was red or orange. All I could see was part of the lower half of a bird. It was sitting in an ordinary sitting posture, with wings drooped and spread a little. Every time it uttered a "dawn song" note the wings were slightly flicked, or perhaps more probably quivered very briefly and slightly. I don't know if this quivering or flicking was ritualized or not. It may have been nothing more than the mechanical after-effect of producing the notes (like the simultaneous tail movements.) I did not watch the birds for a few days after first introducing the orange Buff-throat, because they are all quite shy and I didn't want to get them too excited until the new bird became acclimatized. While casually walking in the area around the cage, however, I did notice quite a lot of chasing in the cage during the first 2 days after orange was introduced. Usually red chasing orange. Sometimes blue chasing orange. There were quite a lot of Wbl phrases during the chasing during the first day. I did not notice R's or R-like sounds the first day.

These appeared to be R's probably lower intensity than many or most of the R's uttered during the dispute described in my notes of May 30,1961. Never included many syllables in a single series. (Most of the R's heard during these chases were very reminiscent of the R's of Summer Tanagers in sound! Some of the R's of the Buff-throats during these chases might possibly be transcribed as "Tit tit tit tit" rather than "Tuk tuk tuk..."). The number of notes per R was somewhat variable. I think the R's with fewest syllables tend to be slower than R's with more syllables. The Buff-throats also uttered a few Wbl's during the chases of the second day, in addition to their R's. By this morning, chasing had greatly diminished in frequency and vigor. I heard only one Wbl during a chase this morning. A few more R's, but not many.

Red hatch marks=Buff-throated (maximus) see Trascription pg46/pg1 May 16 1958]] The Buff-throats have occasionally uttered their high single "Feet" Notes while flying around the cage during the last few days. There must be PCN's or FCN's. I rather incline to think they are the latter, although they sound like the PCN's of many other species. These "Tseet"s are probably identical with the "Wheet"s described above on May 6,1960, p.40, Apr. 17, 1958, p.12, and Apr. 28,1958 p.12. I have also heard quite a lot of similar notes, recently, uttered by flying single wild birds near Frijoles. This morning, every once in a while, when one of the captive birds (usually red) landed near me, it uttered 1 or 2 (usually 1) sharp

Both my captive birds and the wild ones at Frijoles. At Frijoles they are occasionally uttered by single birds in flight (vide Skutch); but only, I think, when the birds are flying to join in a companion and can see the companion already. I can confirm my earlier statement (December 30, 1958, p.23) that the GHAC patterns of the Streaked are intermediate, in form, between the more "typical" GHAC's of some other species and the "chuck" notes of Palm & Blue Tanagers. They seldom or never have the "accelerated diminuendo" effect of the GHAC's of Green-backed Sparrows.

I have also heard it utter a lot of perfectly conventional "incomplete" songs during the last couple of weeks while I have been watching the Green backed Sparrows.

Unfortunately, I could only watch the saltators occasionally, because the Green-backed Sparrows were so active. I noticed that one or both of the saltators uttered quite a lot of GHAC-type notes when it (or they) were moving about very actively. Some of these GHAC's were relatively very sharp. Almost like the clik Notes of the Green-backs. Probably more strongly hostile than less sharp GHAC's. (It is possible that the Streaked Saltators were alarmed by my presence today. Their sharp GHAC-type notes may have contained a strong escape component. If so, they may be strictly homologous with the clik Notes of the Green-backs. I may eventually decide to call them "clik Notes" too.) I shall call this pair of Streaked Saltators "X" from now on the X ♂ sung a lot this morning, around 6:10 a.m. a continuous series of "incomplete" songs.

The notes I have transcribed as "Tseet" above are certainly identical with the notes I transcribed as "Wheet" on previous occasions. I am still a little puzzled about them. They certainly sound as if they should be PN's; but this would be difficult to prove. I watched Blue very briefly early this morning.

The supplanter spends most of time in an St. Posture. [[Like?]] the one drawn at Porto Bello, with breast lowered ("BL"). But bill sometimes almost vertical. Little or no fluffing of ruffling of any kind. Sometimes silent in this posture, At other times quite vocal. When vocal, utters calls consisting of one whistle-like "Tsaweeet" Note, followed by a variable number of Hoarse Notes. Sometimes essentially CHN's. More often HAC-like. There calls would seem to be abbreviated versions of some of the more complex calls I heard during disputes at Porto Bello. Once the supplanted bird uttered a burst of HAC notes just as it landed after being supplanted. A sort of "landing G-HAC". In a completely unritualized sitting posture. Eventually one bird flies off, and all 3 disappear. The St's during this incident were obviously ritualized. And obviously more than [[flight?]] int. movs. Usually assumed facing the bird toward which they were directed. Emphasizing white throat with its black borders Came across a single Black cap 8:00 am.

Flying from bush to bush.

"Tsa-weet"-HAC is definitely the equivalent of the GHAC of the Streaked Saltator (at least in the case of the ♂-I haven't definitely heard both sexes of Black-caps utter much phrases.

I notice both birds have a tendency to "lean" forward, head and neck pointing diagonally upward & forward, with each burst of HAC Notes. Quite a conspicuous contrast with upright posture during preceding notes. Head & bill more or less in line in diagonal posture. During some of the later phrases, one of the birds, almost certainly the [[Venus symbol]] (smaller than its mate) utters a soft, whistled, "ta-ta-wheeeeee-oooo" toward the end of the phrases.

Several times, one of the birds (probably Blue) catches up with another (presumably Yellow) and a violent [[pecking?]] bout develops. These [[pecking?]] bouts accompanied by HAC notes. Always brief. Chase & fighting continues irregularly for some minutes. At one time Blue and Yellow pause for a few seconds, facing one another, about 2 ft apart, Blue perched above Yellow Blue Bowing. High Bow position is [[St?]]. Body more or less horizontal. Underparts [[underline]] very [[/underline]] fluffed. No CR or [[Thflff]]. Wings drooped and [[ipscad]]. [[underlined]] Tail in very extreme [[Tun]] [[/underline]]! Some indications of lateral TF’s; but these are [[light]] and seem to be “impeded”. Blue Wbl’s steadily throughout this period. Wbl’s soft, rapid, as before. Continuous for a considerable period of time. Bill kept [[underline]] slightly [[/underline]] open throughout. Mandibles [[underline]] not [[/underline]] moving to any appreciable extent. While Blue does this, Yellow faces him; looking up at him (this may be St., but difficult to tell) Bill wide open in extreme G. At the same time, Yellow utters series of very [[underline]] soft [[/underline]] and “breathy” HAC notes. Each note separated by definite pause. I shall call such notes “MHAC”. While doing the G-MHAC, Yellow has underparts fluffed and wings drooped. Does not Bow. No CR. The feathers of his throat are slightly ruffled, but not enough to prove that he is performing a ritualized THflff pattern. Yellow seems exhausted and defensive while performing these G-MHAC patterns. They may be high intensity, produced when escape is stronger than attack. [[end page]]
[[underline]] Saltator [[/underline]], May 12, 1962, III 92 [[circled in upper right corner]] [[red pencil lines and marks along left margin]] It seems obvious that Yellow is a ♂. At least, Blue thinks so! Then the chasing and fighting resumes 7:45. We remove Yellow and put him back in his old cage by himself. Also remove Red and put it in a cage by itself. I hope Red is ♀. When we chased Yellow first, at 7:30, before putting him in cage with Red and Blue, he uttered a few "Tseet" notes flying back and forth in his cage. Red and Blue could hear him when he uttered these notes. They immediately began to fly back and forth in their own cage, in an excited, and alarmed-looking, manner. This would suggest that the "Tseet"s are AlCN's. (If so, this may suggest that [[underline]] Saltator [[/underline]] is related to [[underline]] Emberiza [[/underline]]) Yellow uttered HScr's each time when actually caught this morning. This afternoon, I heard Blue begin to utter DC Notes ca. 1:30 pm. Continued for several minutes. Began shortly after rain stopped. Why? Something to do with light intensity? Or the result of having sat immobile during the rain??? These DC Notes were more or less as usual. Ordinary tone and loudness. All or most composed of 4 syllables. Uttered in essentially indeterminate series. Most of the time, the successive notes were essentially identical. [[underline]] But [[/underline]] - every once in a while a brief series of notes would be composed of slightly different notes in regular alternation: "Cheeaweea cheeaweeyoo" [[two pencil marks at bottom of page]]
[[underline]] Saltator, [[/underline]] May 12, 1962, IV. [[circled]] 93 [[/circled]] [[Note: red lines in margin]] Such pairs of notes were slightly reminiscent of the doublets in the KV song of [[underline]] Piranga [[/underline]] and [[underline]] Pheucticus, [[/underline]] in some respects; but I don't think that the pauses before and after each pair of notes were any longer than the pauses between the note of a single pair. I am beginning to think that this Saltator may be quite primitive!!! [[underline]] Saltator, [[/underline]] I June 5, 1962 Barro Colorado Blue has continued uttering DC from time to time. This morning I will put Red back with it. Red put in 6:10. Absolutely exhausted after being chased for five minutes. Just sits in corner, panting. Blue just hops about excitedly. 6:15 Blue flies to Red, lands beside it. Goes into StGHff. Utters lots and lots of "Tseet" Notes. Then flies away again. Then back again. Utters more "Tseet"'s in StGHff. Most "Tseet"'s single. A few double ___ ___ Red ignores him. Then Blue starts to chase Red. Chase silent Then both perch again. 6:20 am. Blue now flying about cage. Silently. Red hidden. 6:25 I walk up to cage, to flush Red. Both birds fly around cage. Usually silent. Occasional single "Tseet" Note by one or both. Then back as before. Blue still flying around. Red hidden. Both silent. Still continuing 6:45 am. Only difference is that Blue not utters occasional single "Tseet" in flight.
[[underline]] Saltator [[/underline]], Jun 5, 1962, II [[right corner, circled]] 94 [[red pencil lines in entire left margin]] 6:46 am. Sudden long aerial chase. Accompanied by many “Tseet” Notes [[eight spaced lines]] Then birds separate again. Red freezes silently in corner. Blue flies about by himself. Largely silent. Utters occasional single “Tseet” Note (I shall call such notes “T” Notes from now on). Blue does a lot of BW when perched between flights. Still continuing as before 6:53 am. Blue quite silent now 7:05 am. More chasing accompanied by “Tseet” Notes. All or most of these “Tseet”s are [[underline]] certainly [[/underline]] uttered by Red, the escaping bird. 7:06 More chasing, just as before. Then separate again. Red freezes on wire side of cage. Blue flies about silently. 7:12 Blue lands beside Red. Goes into StGHff. Apparently with T Notes. Then chases Red. Chase accompanied by both T Notes and [[underline]] R [[/underline]], all jumbled together. Former more common than latter. Then birds separate as before. It is obvious now that T Notes are definitely purely hostile and produced when E is stronger than A (Incidentally, Red uttered some T's when I was trying to catch it before putting it into cage with Blue) But T's are probably not alarm calls. Primarily used during extra-specific disputes. Red remains rather sleek while frozen. No trace of Submissive Ruffle. None of the StGHff's this morning have been accompanied by either CR or Hflff. 7:40 am. More chasing with T Notes 7:42. More chasing. Quite silent Then birds separate as usual
[[underline]] Saltator, [[underline]] Jun. 5 1962, II [[circled]] 95 [[/circled]] [[red lines in margin]] Leaving 8:05 am. as nothing more is developing. 10:00 am. Suddenly notice chasing going on in Red-Blue cage Accompanied by rather thin, stifled HAC Notes "Keeeyah heeyah keeyah keeyah keeyah.... ." Can't see if there are any special postures or movements. When I can see the birds, Red is frozen and silent and Blue is moving about normally. 10:05. Blue suddenly supplants Red. Accompanied by T Notes and 1 brief, stifled HAC Note. Then birds separate again as usual. NOTE: This afternoon I could still hear chases in the Red-Blue cage. Also Blue uttered DC occasionally. So it looks as if Red is ♂. June 6, 1962 Barro, Colorado Watching Red and Blue again. Dark rainy day. 5:50 am. One bird, presumably Blue, is uttering lots of DC. Usual form. No "Cheewink" 's It is still too dark to see what is going on. DC stopped 5:53 AT least one bird flying about, uttering occasional T Notes Then another brief burst DC. Then more flying about. Then more DC Then complete silence. Then an aerial chase (both birds definitely involved) with series T Notes. Then birds separate. One goes back to DCing Then silence again Then more DCing. The DCing bird is Blue Red is frozen on side of cage at the time. 5:59. DCing includes occasional [[underline]] Piranga [[/underline]] -like "Cheewink" Notes 6:01 Blue flying about from perch to perch Uttering burst
[[underline]] Saltator, [[/underline]] Jun. 6, 1962, II [[upper right corner, 96 circled]] [[red lines in margin]] of DC each place. Apparently ignores Red throughout DC performance. I.E. the DC of this species is definitely not even partly hostile. Then Red suddenly moves. Blue immediately chases it back and forth along cage. Chase with some T Notes. Then birds separate. Blue starts DC again. DC still with occasional “cheewink”s. Blue utters DC from almost every possible variety sitting and/or pre-locomotory posture. Quite unritualized. No trace CR, [[Hflff]], or special wing movements. DC never uttered inflight. 6:10 am. Now Blue Shuts up and starts preening. Blue not just flying silently around cage. Leaving 6:20, as it is obvious nothing will develop here. Oh oh. Another chase. Again obvious that it is Red who utters T Notes while escaping. Yesterday morning we let the yellow and purple bird go free. This morning it visited the Red and Blue cage around 9:30 am. (if not earlier) and stayed a long time. It frequently flew back and forth, and around and around, outside the cage, while Blue flew back and forth excitedly inside the cage. Both birds uttered a lot of Wbl’s at such times. Blue (at least) also uttered occasional R’s. Every once in a while, the Yellow bird flew 20 or 30 ft away from the cage, sat, and uttered DC (without Wbl’s). DC perfectly normal in form No “Cheewink”s It is obvious that this Yellow bird was both looking for a mate and attempting to drive out a rival. “Cheewink”, may be an individual peculiarity of Blue
