The Macaulay Library at the Cornell Lab of Ornithology is the world's largest and oldest scientific archive of biodiversity audio and video recordings. Our mission is to collect and preserve recordings of each species' behavior and natural history, to facilitate the ability of others to collect and preserve such recordings, and to actively promote the use of these recordings for diverse purposes spanning scientific research, education, conservation, and the arts.

Here, you'll find a selection of downloadable and USB audio guides produced by the Macaulay Library, and featuring extensive coverage of the vocalizations of North American Birds.
