We've concluded the fourth of five breeding seasons and the results of our team's hard work to date are impressive! More than 1,700 Atlas volunteers together documented the whereabouts and behavior of 6.6 million birds of 242 species.
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!
