The Birds of North America is an online project of the Cornell Lab of Ornithology, based on the print version of BNA which was completed in 2002, a joint 10 year project of the American Ornithologists’ Union, the Cornell Lab of Ornithology, and the Academy of Natural Sciences.
Contents are updated frequently, with online-coordinated contributions from researchers, citizen scientists, and designated reviewers and editors. In addition, BNA Online contains image and video galleries showing behaviors, habitat, nests, eggs and nestlings, and more. And each online species account contains recordings of that bird’s songs and calls, selected from the extensive collection in Cornell’s Macaulay Library of Natural Sounds.
