Overview
The American Ornithological Society (AOS) is a United States-based scientific and professional organization focused on the study, conservation, classification, and understanding of birds. It was established in October 2016 through the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. The merger brought together two long-established ornithological communities and created a unified institution serving researchers, educators, conservation practitioners, students, bird collections, and people with a general interest in birds. Although its membership is centered on professional ornithologists and other researchers, AOS membership is open to anyone interested in birds. The organization offers regular and student memberships, including no-cost Student Membership Awards for eligible undergraduate and graduate students pursuing ornithological careers. It also recognizes distinguished service and scientific achievement through several levels of membership, including Elective Member, Fellow, and Honorary Fellow. These forms of recognition are intended to acknowledge exceptional research, service to the organization, and sustained contributions to ornithology. AOS operates as a scholarly association as well as a standards-setting and professional-development body. Its principal publications are the quarterly journals Ornithology, formerly titled The Auk, and Ornithological Applications, formerly titled The Condor. The society also publishes the AOS Checklist of North American Birds, a major reference for bird classification and English-language nomenclature, along with the Ornithological Monographs series. Through its journals, meetings, awards, committees, and research-support activities, AOS provides infrastructure for the exchange of ornithological knowledge. One of the society's most consequential institutional functions is its work on taxonomic classification and standardized bird names. The North American Classification Committee develops and maintains classifications and English names for birds of North and Middle America. The South American Classification Committee performs a comparable role for South America. These committees review evidence and publish decisions that influence field guides, scientific literature, conservation programs, databases, and public communication. In October 2023, AOS announced a program to replace English bird names associated with individual people, with the stated aim of removing names connected to figures whose histories include racism or other problematic conduct. The proposed process emphasized descriptive names based on habitat, appearance, behavior, or other characteristics and included public participation. The initiative generated both support and disagreement within the birding community. The society's broader work is carried out through standing committees dealing with subjects such as bylaws, history, membership, student affairs, bird collections, classification, and nomenclature. Its Committee on Bird Collections engages with museums and other institutions that hold avian specimens, including issues concerning collection inventories and permits for possessing or transporting specimens. AOS also supports early-career researchers and students through travel, presentation, research, membership, and professional awards. AOS is not a consumer-goods brand or a publicly traded company. Its principal offerings are scholarly publications, taxonomic standards, conferences, awards, membership services, professional networks, and educational resources. The organization's historical roots extend to the founding of the American Ornithologists' Union in 1883, while its current identity reflects the 2016 consolidation with the Cooper Ornithological Society. It continues to serve the ornithological community in North America and throughout the Americas while contributing to international scientific and conservation discussions.
History
The institutional history of the American Ornithological Society reaches back to the American Ornithologists' Union, founded in New York City in 1883. The initiative was organized by Elliott Coues, J. A. Allen, and William Brewster, who invited prominent ornithologists to a convention intended to establish an organization modeled in part on the British Ornithologists' Union. Twenty-one ornithologists attended the founding meeting on September 26, 1883, held in the library of the American Museum of Natural History. Additional individuals were elected as founding members even though they could not attend, including Smithsonian figure S. Baird and J. A. Allen. The AOU developed into one of the principal professional organizations for ornithology in the Western Hemisphere. Its activities included scholarly publishing, scientific meetings, professional recognition, membership programs, and the development of standards for bird classification and English names. Its journal The Auk began publication in January 1884 and became a long-running venue for ornithological research. The organization also supported scientific awards, student participation, bird collections, and the maintenance of authoritative taxonomic information. A second major institutional predecessor was the Cooper Ornithological Society. By 2013, the AOU and Cooper Ornithological Society had moved toward a close partnership. Their collaboration included joint meetings, centralized publishing operations, and a reorientation of their respective journals. The arrangement was intended to reduce duplicated infrastructure, improve publishing efficiency, and create a stronger professional community for ornithologists. In October 2016, the AOU ceased operating as an independent organization and merged with the Cooper Ornithological Society to form the American Ornithological Society. The new society retained and expanded the functions associated with both predecessors. It continued scholarly publishing through the successor journals Ornithology, formerly The Auk, and Ornithological Applications, formerly The Condor. It also continued publication of the AOS Checklist of North American Birds and maintained classification committees for North and Middle America and South America. AOS's work is distributed across a network of standing committees. General committees address organizational governance, history, and membership, while specialized groups work on bird collections, classification, nomenclature, and student affairs. The Committee on Bird Collections monitors the condition and documentation of avian specimen collections, maintains relationships with institutions that hold those collections, and addresses practical matters such as permits for the possession and transport of specimens. The North American Classification Committee develops standardized classifications and English names for birds in North and Middle America. The South American Classification Committee performs related work for South American birds. The society also developed programs intended to sustain the next generation of ornithologists. A decline in student membership across ornithological organizations led to the creation of a Student Affairs Committee in 2003. Beginning in 2005, AOU-related student programs included membership support, travel assistance, presentation awards, and other activities at annual meetings. These programs continued within the AOS structure and complement the society's broader professional awards. AOS recognizes senior and early-career achievement through awards including the William Brewster Memorial Award, Elliott Coues Award, Loye and Alden Miller Research Award, Ralph W. Schreiber Conservation Award, James G. Cooper Young Professional Awards, and Ned K. Johnson Young Investigator Award. Student programs include membership awards, travel awards, and presentation awards for research in areas such as conservation and avian behavior. In October 2023, AOS announced a significant nomenclature initiative: English bird names linked to individual people would be reconsidered and replaced. The society presented the initiative as an effort to remove commemorative names associated with racism and to adopt names describing birds' habitats, physical characteristics, behaviors, or other intrinsic features. Public input was part of the proposed process. The initiative involved more than 100 species across the Americas and prompted a range of reactions, illustrating the cultural and scientific significance of standardized bird names. Today, the American Ornithological Society functions as a membership organization, scholarly publisher, scientific standards body, award administrator, and convening institution. Its work connects academic ornithology with museums, conservation organizations, students, professional researchers, and the wider birding public. While its principal organizational base is in the United States, its scientific scope covers the Americas and its publications and standards are used by an international ornithological community.
