What Bird is That? A Pocket Museum of the Land Birds of the Eastern United States Arranged According to Season

"What Bird is That?" by Frank M. Chapman is a handbook designed for those interested in the bird life of Eastern North America. Written in the style of an early 20th-century field guide, the book helps readers identify birds, understand their behaviors, and follow their migration patterns. Chapman, who worked at the American Museum of Natural History, shares how museum collections are organized to assist students in recognizing local birds. He focuses on the importance of knowing which birds are present during different times of the year, providing a month-by-month look at the birds most likely to be seen, from winter birds to those passing through during migration. The book gives bird watchers advice on what equipment to use, how to take notes, and how to match the birds they see with pictures to accurately identify them.
