American Ornithological Society

The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists although membership is open to anyone with an interest in birds. The AOS is a member of the Ornithological Council and Ornithological Societies of North America (OSNA). The society publishes the two scholarly journals The Auk and The Condor as well as the AOS Checklist of North American Birds.
