The data sheets and maps document the swamp sparrow census conducted by Russell Greenberg during May and June 2004. Sheets are preprinted; sometimes information is recorded by hand, sometimes printed on the sheet. Sheets list observer name, date, time, point (e.g. 82), sky code, wind code, followed with a table of data listing bird species observed with sex, detection (V, C, S), substrate, and a description of vegetation coverage. This lists types of vegetation type and percentage of covered observed. Some sheets include comments. Locations are in Delaware.
