Field notes Hoyt created from 20 May to 16 August 1939 while documenting the development of a group of young pileated woodpeckers and later also flickers from the time they hatched. Most of the notes pertain to 3 young pileated woodpeckers. Notes comment on weight and stages of development such as sitting upright. The notes also document Hoyt's observations of feeding schedules, activities, and behavior. Several sketches in the notebook illustrate markings and patterns on the birds. Two other sketches on loose paper were inserted into the notebook. At the beginning of the notebook is a weight table for three of the pileated woodpeckers recording the following: day, date, red male weight, white female weight, nothing female weight, and notes. A table for the flickers records measurements for three days in June. Locality is unknown, but possibly in Ithaca, NY, where Hoyt lived.
