Conserve Wisconsin birds by joining our bird survey

The Wisconsin Breeding Bird Atlas II is a comprehensive field survey that documents the distribution and abundance of birds breeding across our state.

Birds are an essential part of Wisconsin’s culture and ecology. Yet many species face grave threats from habitat loss, climate change, and other human-caused pressures and nearly one-third are imperiled or will be without intervention. To conserve them, we need a current understanding of birds that rely on Wisconsin to breed and raise their young. These insights help us identify the conservation needs of breeding birds and try to meet those needs. Wisconsin Breeding Bird Atlas II mobilizes volunteers across the state to accomplish this — we need your help to document which birds are breeding in your area!

Volunteering is easy and fun!

Put your love of birds to work and learn to birdwatch in a new way by closely observing bird behavior and reporting the data online. It’s easy! Sign up to observe birds near your home, your favorite birding spots, and in atlas priority blocks. Report your observations of bird behavior online using our dedicated Wisconsin Breeding Bird Atlas II eBird portal.
