Heath Hen Census - 1927

This series contains notes taken by Alfred Gross, his Bowdoin College students, and other scientists. There are working drafts of Gross' publications, often with multiple drafts of the same publication at different stages in the writing process. These drafts are both handwritten and typed and include corrections and editorial remarks. There are some early drafts of work by other scientists as well as research performed by Gross' students. The Heath Hen, Ruffed Grouse, Snowy Owl, and Goshawk represent major topics in Gross' work and there are large portions in this series devoted to them (Owls and hawks are treated as one topic). The different animals are discussed in correspondence folders spanning several years each. Notes and drafts of reports and publications can also be found. Because of the collaborative effort involved in much of this research there are often letters and reports not authored by or directed to Gross. There are also data sheets and questionaries discussing the Ruffed Grouse and "owls and hawks" in detail. The time periods in which Gross researched these birds overlap and many of the items address more than one species.
