You’re invited to join us for the American Ornithological Society (AOS) 2025 meeting. This will be the 143rd annual meeting of AOS.

Date: 11–15 August 2025
Location: St. Louis, Missouri
Venue: Hyatt Regency St. Louis at The Arch

Following our long legacy of vibrant annual meetings, the 2025 conference will once again offer a great opportunity for sharing and discussing scientific research in all areas involving birds.

We envision a broad discussion of research that spans the breadth of modern ornithology through plenaries, symposia, workshops, roundtable discussions, contributed papers, and posters. In addition to these exciting presentations, we will have a variety of exhibitors from the commercial, non-profit, and government sectors. We will also host a series of daily, fun networking events for you to make new connections and reconnect with colleagues!
