Facts And Circumstances Test
THE AMERICAN ORNITHOLOGICAL SOCIETY (AOS) RECEIVES A SUBSTANTIAL AMOUNT OF SUPPORT FROM A COMBINATION OF GOVERNMENT AGENCIES AND CONTRIBUTIONS FROM THE GENERAL PUBLIC, VIA BOTH DIRECT AND INDIRECT CONTRIBUTIONS. IN 2022, THE AOS RECEIVED 31.74% OF ITS SUPPORT FROM GOVERNMENT AND PUBLIC SOURCES. THE AOS IS ORGANIZED AND OPERATED TO ATTRACT NEW AND ADDITIONAL PUBLIC AND GOVERNMENTAL SUPPORT ON A CONTINUOUS BASIS. THE FACTS AND CIRCUMSTANCES THAT AOS IS PUBLICLY FUNDED ARE BASED ON AOS FUNDING, POLICIES, PUBLICATIONS, PROGRAMS, AND MEMBERSHIP. ORGANIZED IN 1883, AND INCORPORATED IN 1888, THE AOS' INVESTMENT HOLDINGS ORIGINATE FROM CONTRIBUTIONS FROM MULTIPLE AND VARIED MEMBERS OF THE GENERAL PUBLIC, INCLUDING THOUSANDS OF INDIVIDUAL DONORS WITH AN INTEREST IN ORNITHOLOGY, AND LIFE MEMBERSHIP DUES FROM OUR 510 LIFE MEMBERS. THESE ENDOWMENT HOLDINGS CONTRIBUTE SUBSTANTIAL FUNDING EACH YEAR TO SUPPORT AOS' OPERATIONS AND PROGRAM DELIVERY THAT APPEAL TO BROAD AUDIENCES OF INDIVIDUALS AND INTERESTS. THE AOS IS A MEMBER ORGANIZATION WITH CONSISTENT MEMBER NUMBERS BETWEEN 2500 AND 3000 MEMBERS ANNUALLY, AND A ROBUST MEMBERSHIP OF 2820 IN 2022. WE ATTRACT NEW MEMBERS EACH YEAR, WITH 435 NEW MEMBERS IN 2022, 15.4% PERCENT OF OUR TOTAL 2022 MEMBERSHIP. OUR ROBUST PROGRAMS TO SUPPORT STUDENT MEMBERSHIPS ENSURE THAT WE ATTRACT NEW MEMBERS AS INDIVIDUALS BEGIN CAREERS IN THE ORNITHOLOGICAL FIELD. IN ADDITION, AOS'S ANNUAL SCIENTIFIC CONFERENCES, WHICH ATTRACT ~800 INDIVIDUALS FROM AROUND THE WORLD, ALSO ATTRACT INCREASING AMOUNTS OF PUBLIC SUPPORT AND SPONSORSHIP. IN 2022, OUR ANNUAL MEETING ATTRACTED $137,700 OF SPONSORSHIP DOLLARS FROM FEDERAL AND LOCAL GOVERNMENTS AND OTHER NON-PROFIT ORGANIZATIONS, COMPARED TO $33,250 IN 2021. IN 2022 AND 2023, THE AOS FOCUSED ON MULTIPLE PLANNING EFFORTS, THE IMPLEMENTATION OF WHICH WILL CONTINUE TO ATTRACT PUBLIC SUPPORT. IN 2021 AND 2022, THE AOS DEVELOPED A DIVERSITY, EQUITY, INCLUSION, BELONGING AND JUSTICE (DEIBJ) ACTION PLAN THAT IS NOW REFLECTED IN OUR NEW 2023 STRATEGIC PLAN. OUR DEIBJ PLAN WILL HELP TO PROVIDE A MORE INCLUSIVE AND WELCOMING COMMUNITY THAT SUPPORTS SCIENTISTS OF ALL BACKGROUNDS AND IDENTITIES. IN ADDITION TO ATTRACTING NEW MEMBERS AND INDIVIDUAL DONORS, THESE EFFORTS ALLOW US TO ATTRACT ADDITIONAL SOURCES OF GOVERNMENT SUPPORT; THE AOS WAS THE RECIPIENT OF TWO SIGNIFICANT FEDERAL SUBAWARDS IN 2022 AND 2023 AIMED AT EXPANDING SCIENTIFIC ACCESS THROUGH SUPPORT OF DIVERSE PEOPLE GROUPS. A NEW STRATEGIC INITIATIVE LAUNCHED IN LATE 2023, TO CHANGE ENGLISH COMMON NAMES OF BIRDS NAMED AFTER PEOPLE, WILL ATTRACT SIGNIFICANT SUPPORT IN 2024 AND FOR SEVERAL YEARS AFTER THAT, FROM A MORE DIVERSE SEGMENT OF THE PUBLIC. AOS GOVERNING BODY (COUNCIL) IS ELECTED BY OUR BROAD AND DIVERSE MEMBERSHIP, ACCORDING TO THE AOS'S BYLAWS. COUNCILORS ARE GENERALLY INDIVIDUALS WHO ARE EMPLOYED BY ACADEMIC INSTITUTIONS, NON-PROFIT ORGANIZATIONS, OR GOVERNMENT AGENCIES, AND THEY HAVE SPECIALIZED KNOWLEDGE AND EXPERTISE WITHIN THE FIELD OF ORNITHOLOGY. THE GOVERNING BODY REPRESENTS THE BROAD INTEREST OF OUR BROAD AND DIVERSE MEMBERSHIP. THE AOS PROVIDES SERVICES WIDELY USED BY COLLEGES, UNIVERSITIES, GOVERNMENT EMPLOYEES, AND MEMBERS OF THE GENERAL PUBLIC OR INVITES PUBLIC PARTICIPATION IN PROGRAMS AND POLICIES. THE AOS PUBLISHES TWO SCHOLARLY JOURNALS, ORNITHOLOGY AND ORNITHOLOGICAL APPLICATIONS. THESE PUBLICATIONS, RESPECTIVELY, PUBLISH ORIGINAL RESEARCH THAT TEST FUNDAMENTAL, SCIENTIFIC HYPOTHESES THROUGH ORNITHOLOGICAL STUDIES AND ADVANCE THE UNDERSTANDING OF LIVING OR EXTINCT BIRD SPECIES AND PUBLISH ORIGINAL RESEARCH, SYNTHESES, AND ASSESSMENTS FROM ALL PARTS OF THE GLOBE FOCUSING ON THE APPLICATION OF THE SCIENTIFIC THEORY, ORNITHOLOGICAL KNOWLEDGE AND METHODS TO THE CONSERVATION AND MANAGEMENT OF BIRDS, AND TO POLICY. UNIVERSITIES AND INSTITUTIONS ARE MAJOR SUBSCRIBERS OF THE JOURNALS. AFTER ONE YEAR, ALL ARTICLES ARE FREELY AVAILABLE TO THE PUBLIC. THE AOS FURTHER ENGAGES THE PUBLIC THROUGH OUR PRODUCTION OF THE CHECKLIST OF NORTH AND MIDDLE AMERICAN BIRDS, WHICH PROVIDES THE TAXONOMIC AND NOMENCLATURAL FOUNDATION FOR BIRD RESEARCH, CONSERVATION, AND EDUCATION IN NORTH AND MIDDLE AMERICA, AND THE CHECKLIST OF SOUTH AMERICAN BIRDS, WHICH SERVES A SIMILAR PURPOSE IN SOUTH AMERICA. CHECKLISTS PROVIDE THE SCIENTIFIC TAXONOMIC NAMES OF SPECIES AS WELL AS THEIR COMMON NAMES. THESE NAMES ARE USED BY MILLIONS OF PEOPLE GLOBALLY, FROM PROFESSIONAL ORNITHOLOGISTS, TO CASUAL BIRDWATCHERS, TO LAND MANAGERS, TO BOOK AUTHORS. THE AOS COUNCIL ANNOUNCED A COMMITMENT IN NOVEMBER 2023 TO CHANGE ALL ENGLISH LANGUAGE NAMES OF BIRDS WITHIN ITS GEOGRAPHIC JURISDICTION THAT ARE NAMED DIRECTLY AFTER PEOPLE, AND TO ENGAGE THE PUBLIC IN COMING UP WITH NEW, DESCRIPTIVE NAMES FOR THESE SPECIES. THIS INITIATIVE, WHICH WILL LAUNCH IN 2024, WILL ENSURE EVEN MORE BROAD AND CREATIVE PUBLIC ENGAGEMENT WITH THE AOS AND ITS PROGRAMS IN THE FUTURE. THE AOS IS THE LARGEST PROFESSIONAL ORNITHOLOGICAL SOCIETY IN THE WESTERN HEMISPHERE AND ATTRACTS A SIGNIFICANT PERCENTAGE OF US-BASED ORNITHOLOGISTS, AS WELL AS ORNITHOLOGISTS FROM ACROSS THE GLOBE. AS A MEMBER ORGANIZATION, THE AOS SEEKS TO ENROLL A SUBSTANTIAL NUMBER OF INDIVIDUALS THROUGHOUT THE ORNITHOLOGICAL COMMUNITY. OUR MEMBERSHIP RATES ARE DESIGNED TO MAKE MEMBERSHIP ACCESSIBLE TO A BROAD RANGE OF SCIENTISTS ACROSS CAREER STAGES, INSTITUTIONS, AND GEOGRAPHIES. THE AOS' GOVERNING BODY AND MEMBERSHIP COMMITTEE REGULARLY EVALUATE MEMBER BENEFITS, BARRIERS TO MEMBERSHIP AND MAKE RECOMMENDATIONS AND SUGGESTIONS FOR WAYS TO IMPROVEMENTS, WHEN DEEMED NECESSARY.
