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

We Did It: All 1,283 Atlas Blocks Complete!

68316952 2328467650752026 9194751719118995456 nWe started this season with 500 blocks left to finish. But thanks to your energy, dedication, and grit, all 1,283 priority and specialty Atlas blocks in Wisconsin have been marked complete!

We can all be proud of this phenomenal effort, representing the work of more than 2,000 people and five years of data collection. From the Apostle Islands of Lake Superior, to the bluffs and backwaters along the Mississippi, to the agricultural fields of southern Wisconsin, volunteers from across the state came together to complete the Atlas.

Conserving Wisconsin Birds

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 mobilized 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!
