Birds of North America
Birds of North America (BNA) is a rich series of species accounts with extensive information about birds that occur regularly in Canada and the United States. A companion series on Neotropical Birds covers species from Mexico and the Caribbean through South America. Each account contains information on distinguishing characteristics, distribution, systematics, behavior, ecology, demography, conservation, and priorities for future research.

The BNA series was produced as a collaborative effort of the former American Ornithologists' Union, the Cornell Lab of Ornithology, and the Academy of Natural Sciences. It was first published in print over a period of 10 years, with 18 volumes completed in 2002. It is now published online through the Cornell Lab of Ornithology.
