The Auk: Ornithological Advances

The Auk: Ornithological Advances is one of two scientific journals published by the American Ornithological Society (along with The Condor: Ornithological Applications), both accessible to AOS members free of charge.

auk-cover-jan-2017.jpgThe Auk has been published continuously since 1884 (originally by the American Ornithologists’ Union). It was honored in 2009 as one of the 100 most influential journals of biology and medicine over the past 100 years. Today, it remains at the top of peer-reviewed journals focusing on birds, with one of the highest Journal Impact Factors among ornithological journals worldwide.

Beginning in 2014, The Auk became The Auk: Ornithological Advances, an international journal that that advances fundamental scientific knowledge in two ways: increase in the basic knowledge of bird species, both living and extinct; and increase in the knowledge of broad biological concepts through studies of bird species.
