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. Checks can be mailed to:
