AMERICAN ORNITHOLOGICAL SOCIETY

What is the American Ornithological Society (AOS)? We're a diverse, global network of empowered professionals, working together to advance the scientific study and conservation of birds. The world's largest international ornithological society, the AOS is more relevant today than ever, and we're dedicated to supporting the scientists doing this critical work-for the sake of birds, humanity, and the planet... The AOS was formed in 2016 with the merger of the American Ornithologists' Union (AOU), founded in 1883, and Cooper Ornithological Society (COS), founded in 1893.
