AOU Checklist of North American Birds

The AOU Checklist of North American Birds is the official source for taxonomy of birds in North America. It is published by the American Ornithologists' Union. The North American Classification Committee (NACC) considers proposals related to classification and nomenclature, and produces the Checklist and makes major revisions (editions) and minor updates (supplements). The 11th supplement to the seventh edition was released in July 2011.[1]
