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

WIsconsin has a rich diversity of bird species, with more than 400 species recorded in the state. There are many ways to learn more about the birds that occur here. WSO has compiled many of these resources on this page, including field trip opportunities, publications, and links to other bird-related organizations.


WSO Bird TV

Bird TV is a series of educational videos covering topics related to wild birds. The episodes feature original images and video of Wisconsin birds collected by some of the state's finest photographers. The series is written and produced by Steve Betchkal in conjunction with WSO.


Atlas of the Breeding Birds of Wisconsin

WSO initiated the first Wisconsin Breeding Bird Atlas in 1995. The Atlas provides informative accounts and distribution maps for all of the breeding birds in our state. WSO is currently working with partners to plan the second atlas effort.


Bird Monitoring Kits

WSO and the Wisconsin Bird Conservation Initiative developed Bird Monitoring Kits to allow educators and students to study birds and their habitats and thereby gain a greater appreciation of the natural world. Bird Monitoring Kits contain the tools to help introduce students to the local bird community, build their skills in bird identification, and help them gain knowledge of bird natural history.


WSO Speakers Bureau

WSO maintains a list of individuals who are willing to give programs on birds and bird-related topics. This list is compiled for the use of bird clubs, Audubon Societies, nature centers, classes, and other groups interested in birds.
