TheAmerican Ornithological Society (AOS) is anornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and theCooper Ornithological Society.[1] Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals,Ornithology (formerlyThe Auk) andOrnithological Applications (formerlyThe Condor) as well as theAOS Checklist of North American Birds. The American Ornithological Society claims the authority to establish standardized English bird names throughout North and South Americas.[2]
In 2013, the American Ornithologists' Union (AOU) announced a collaboration with the Cooper Ornithological Society, streamlining operations through joint meetings, a shared publishing office, and a reorientation of their journals. By October 2016, the AOU ceased its independent status, merging with the Cooper Ornithological Society to establish the unified American Ornithological Society.


The American Ornithologists' Union was founded in 1883. Three members of theNuttall Ornithological Club,Elliott Coues,J. A. Allen, andWilliam Brewster, sent letters to 48 prominent ornithologists inviting them "to attend a Convention ofAmerican Ornithologists, to be held in New York City, beginning on September 26, 1883, for the purpose of founding an American Ornithologists' Union, upon a basis similar to that of the "British Ornithologists' Union." The addressees were selected mainly because of their "scientific standing, but somewhat with regard to geographical representation, it being desirable to make the gathering as catholic and non-sectional as possible." Twenty-five responded to the letter and 21 were present at the first meeting.[3]The founding convention was held in the library of theAmerican Museum of Natural History on September 26, 1883. Founding members of the AOU include those present at the inaugural convention, listed below. In addition, the members of the new Union unanimously enrolled two others as founding members:Professor S. Baird, who was unable to attend due to his duties at theSmithsonian, andJ. A. Allen, who could not attend due to physical disability.[3]
In 2013, the American Ornithologists' Union announced a close partnership with the Cooper Ornithological Society, including joint meetings, a centralized publishing office, and a refocusing of their respective journals to increase efficiency of research.[4] In October 2016, the AOU announced that it was ceasing to operate as an independent union and was merging with the Cooper Ornithological Society to create the American Ornithological Society.[5]
In October 2023, the AOS announced that it was set to rename all bird species associated with individuals, aiming to eliminate names linked to figures with racist pasts. Aiming for more descriptive names based on habitat or physical features, the renaming process would involve public input. Over 100 avian species across the Americas would undergo this change, with the move eliciting mixed reactions within the birding community.[2]
Regular membership in the AOS is open to any dues paying person with an interest in birds. Student rates are available for full-time students.Student Membership Awards of a no-cost membership are available to qualified undergraduate and graduate students who wish to pursue a career in ornithology.[7] There are three higher classes of membership,Elective Member,Honorary Fellow andFellow.[8]
Elective Members are selected "for significant contributions to ornithology and/or service to the Union." When elected, they must reside in the Western Hemisphere. A proposedElective Member must be nominated by threeFellows orElective Members and more than half of theFellows andElective Members must vote for the proposed member to be declared elected.[8]
Honorary Fellows are limited to 100 and are "chosen for exceptional ornithological eminence and must at the time of their election be residents of a country other than the United States of America or Canada." Nominations forHonorary Fellow are by a special committee appointed by the president or any threeFellows. A vote of the majority of theFellows present at an annual meeting is required for election. EachFellow may vote affirmatively for as many as there are vacancies.[8]
Fellows are chosen "for exceptional and sustained contributions to ornithology and/or service to the Union" and must be residents or citizens of the Western Hemisphere when elected. Candidates must be anHonorary Fellow orElective Member in good standing. A vote of two thirds of theFellows at an annual meeting is required for election as aFellow.[8]
The quarterly journal,Ornithology (formerlyThe Auk), has been published since January 1884. The quarterly journal,Ornithological Applications (formerlyThe Condor), has been published since 1899. Other significant publications include theAOS Checklist of North American Birds, which is the standard reference work for the field, and amonograph series,Ornithological Monographs.
The AOS presents annual awards to recognize achievements and service, support research, and encourage student participation.
The AOS recognizes members' outstanding contributions to ornithological science through four senior professional awards and three early professional awards:
A decline in student membership in the AOU and other ornithological societies prompted creation of aStudent Affairs Committee in 2003. Several awards for students were created starting in 2005 as well as activities for students at annual meetings.
Much of the AOS's work is accomplished by its thirty-three standing committees. Many of these are common for any organization such as Bylaws, History and Membership. Other committees are of special importance to ornithology.[16]
