The Atlas of North America‘s Migratory Birds

A state-of-the-art migratory atlas of North American birds—the first resource of its kind More than 70 percent of North American bird species are migratory, traveling annually between separate breeding and nonbreeding areas. While we know the overall ranges of species, we have lacked an understanding of where specific populations move to across seasons and regions—but these limitations are rapidly disappearing. Thanks to the contributions of thousands of bird banders and researchers over the past century and recent efforts to develop and deploy ever smaller tracking devices, it is now possible to map where different breeding populations migrate and spend the nonbreeding season. The Atlas of North America’s Migratory Birds brings these findings together in one place, presenting a treasure trove of data for hundreds of species along with detailed range maps derived from eBird data for each species. Covers nearly 600 species Compiles diverse data types from thousands of contributors Brings together banding data collected over the past century with information gathered using the latest tracking technology, stable isotopes, and genetic tools Features eBird maps for every species, published here for the first time An essential and definitive resource for ornithologists, conservationists, and birdwatchers
