Welcome to AOS 2025 in St. Louis!
We are thrilled to invite you to the 143rd annual meeting of the American Ornithological Society in St. Louis, Missouri, 11–15 August 2025. This year’s theme, “Avian Gateways: Connecting Ornithology and Conservation,” highlights the critical need to bridge scientific discovery and management action to drive meaningful change for birds in a rapidly shifting world. Our gathering will celebrate the power of collaboration, the resilience of birds, and the collective determination of the ornithological community to address environmental challenges with hope and purpose.
We have planned five exciting days of scientific exchange, professional development, and community building. The meeting will feature stimulating plenaries, symposia, workshops, and roundtables, along with opportunities to showcase groundbreaking research, foster interdisciplinary dialogue, and strengthen the connections between science and conservation practice. We invite ornithologists, conservation practitioners, educators, and students to engage in discussions that will enhance our collective ornithological knowledge and promote positive best practices for birds and the ecosystems they depend on.
St. Louis offers a dynamic setting for our meeting, rich with history, biodiversity, and conservation innovation. Attendees can explore the region’s vibrant birding hotspots, including the confluence of the Mississippi and Missouri rivers—key migratory corridors for countless species. Our social events will provide ample opportunities to reconnect with colleagues, form new collaborations, and enjoy the culture and hospitality of this gateway city.
On behalf of the Meeting Coordination Committee and our local hosts, we warmly welcome you to AOS 2025. Mark your calendar and stay tuned for registration details. We look forward to gathering with you in St. Louis to forge new pathways for birds and the people working to protect them.
See you in St. Louis!
