Promoting the enjoyment, study, and conservation of Wisconsin's birds.

The Wisconsin Society for Ornithology is a volunteer, nonprofit organization that was established in 1939. Our mission is to promote the enjoyment, study and conservation of Wisconsin’s birds. We provide opportunities for all people to enjoy resident and migratory birds, while being a leading steward of and ambassador for Wisconsin birds. WSO sponsors birding field trips throughout the year, hosts an annual birding convention, publishes a quarterly journal and monthly newsletter, offers research grants, and serves as an informational resource center on bird-related issues. Membership exceeds 1,400 from across the United States and around the world.
