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.
