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, including beginners, backyard enthusiasts, conservationists, community science participants, and professional ornithologists. Your membership dues and donations enable us to support bird-related research, conservation and education in Wisconsin and to strengthen the state’s birding community through impactful collaborations and partnerships. 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 additional information, please contact us at
