Introducing the New Birds of North America

Birds of North America (BNA) is the most comprehensive reference for the life histories of over 760 bird species that breed in the United States and Canada. Species accounts are written by ornithologists and other experts and are an essential reference for anyone with an advanced interest in birds. BNA accounts have always offered an in-depth, authoritative summary of scientific literature and media. However, in combination with the Macaulay Library and eBird, our restructured species accounts are now accompanied by new sounds, images, and video, and distributional maps and model output generated by eBird.
