AOU Checklist of North and Middle American Birds (7th Edition and Supplements)

The "AOU Checklist" is the official source on the taxonomy of birds found in North and Middle America, including adjacent islands. This publication is produced by the North American Classification Committee (NACC), an official committee of the AOU.

The geographic area covered includes: North and Middle America from the North Pole to the boundary of Panama and Colombia, including the adjacent islands under the jurisdiction of the included nations; the Hawaiian Islands; Clipperton Island; Bermuda; The West Indies, including the Bahama Islands, the Greater Antilles, Leeward and Windward Islands in the Lesser Antilles (ending with Grenada); and Swan, Providencia, and San Andrés Islands in the Gulf of Mexico. Greenland is not included in the coverage of the Seventh Edition of the Check-list, although it was included in earlier editions and will be in the next edition.

The last edition of the AOU Check-list to include subspecies was published in 1957 (5th edition). Although a complete revision of North American avian subspecies has not been done, we refer readers to Avibase and the Birds of North America Online for more up-to-date treatments of subspecies. The Birds of North America project is systematically revising subspecies account for North American birds (see list of accounts revised to date (PDF).
