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

The Wisconsin Society for Ornithology is grateful for the outstanding support of our programs provided by our members. Year after year, WSO members have gone beyond the basics of renewing their membership annually – which in itself helps support our programs – and have contributed to one or more of our special funds. It is because of members’ continued donations that WSO is able to offer programs that have positive impacts on the birds of Wisconsin, through research, conservation, and support of young birders.

WSO is a 501(c)(3) nonprofit organization, and donations are fully deductible to the extent allowed by law. Our Federal Tax ID number is 39-6040605. If you are interested in supporting our efforts by making a monetary donation, you can contribute to one of our special funds below by using your credit card or your PayPal account.

Special Funds

Unrestricted Donations

Help support WSO’s vision: to provide opportunities for all people to enjoy resident and migratory birds, while being a leading steward of and ambassador for Wisconsin birds. Donations to this fund support the ongoing general operations of WSO.

Youth Fund

Encourage and support young birders! Donations to this fund support our Youth Education grant, Bird Kit program, and other WSO activities that further the appreciation of birds and bird-related issues among Wisconsin’s youth.

Honey Creek Fund

Help to preserve and manage this unique 267-acre property that WSO has owned since 1960. More than 180 bird species have been recorded at the preserve, including unusual nesting species such as Acadian flycatcher, Louisiana Waterthrush, and Cerulean Warbler. Donations help to fund invasive species control and other land management activities, property taxes, as well as maintenance of WSO’s Cox Nature Center.

Conservation Fund

Help advance bird conservation in Wisconsin! Donations support WSO’s leadership role in bird habitat management, conservation, and research and allow us to take action on conservation issues that threaten bird habitat.

Wisconsin Breeding Bird Atlas II

Support bird research in Wisconsin! The first Wisconsin Breeding Bird Atlas (WBBA) was initiated by WSO in 1995 and represented the largest coordinated field effort in the history of Wisconsin ornithology. The second Atlas project will provide a new snapshot of species distribution in our state and elevate public awareness of Wisconsin’s bird community. Donations support ongoing general operations of the second Atlas project. Click here to make a donation to the Atlas or Sponsor-a-Species.

Wisconsin eBird Portal

Join WSO in supporting eBird, the nationwide database of bird sightings. This online checklist program has revolutionized the way the birding community reports and accesses information about birds. Donations help to maintain the Wisconsin eBird portal.
