Ornithology, formerly The Auk and The Auk: Ornithological Advances, is a peer-reviewed scientific journal and the official publication of the American Ornithological Society (AOS). It was established in 1884 and is published quarterly. The journal covers the anatomy, behavior, and distribution of birds. It was named for the great auk, the symbol of the AOS. In 2018, the American Ornithology Society announced a partnership with Oxford University Press to publish The Auk: Ornithological Advances and The Condor: Ornithological Applications .
