Join the Wisconsin Society for Ornithology

WSO provides opportunities for all people to enjoy resident and migratory birds, while being a leading steward of and ambassador for Wisconsin’s birds. We welcome all birders – young and old – beginners, backyard enthusiasts, tourists, conservationists, and professional ornithologists. Your membership dues and donations will enable us to produce our publications, events and programs, strengthen the state’s birding community and support bird-related research, conservation and education in Wisconsin. Because WSO is a nonprofit 501(c)(3) organization, you may deduct as a charitable donation any donation you make to WSO or one of its special funds. For membership information, please contact Mary Murrell at
