USED - The summer Atlas of North American Birds

Regular price $5.00

The North American Breeding Survey comprises a network of regularly censussed, road-based survey routes and constitutes the most comprehensive set of data on the relative abundance and population trends of these birds during the summer months. In this book, Jeff and Amy Price and Sam Droege have used these data to create detailed, computer-generated maps showing the relative abundance of 449 species that summer in the contiguous United States and southern Canada. Tabular information on distribution hotspots for these, and an additional 50 species too local in occurrence to map effectively, are also presented. The maps provide a baseline for future and more regionally based studies.
