The Birds of North America (BNA) provides encyclopedic coverage of the biology of North American breeding birds, with species accounts written by recognized experts. The BNA project was initiated in 1992 as a collaboration between the Academy of Natural Sciences and the American Ornithological Society (AOS), and BNA continues to work closely with AOS's BNA Advisory Committee to this day. Initially produced in hard copy, the Cornell Lab of Ornithology along with BNA's first editor, Alan Poole, spearheaded the second generation of the project by establishing BNA Online in 2004, and account revisions have been ongoing since that time.
