Celebrate the 15th anniversary of the Great Wisconsin Birdathon and the 40th anniversary of The Natural Resources Foundation of Wisconsin! NRF's Great Wisconsin Birdathon is the state's largest fundraiser for bird conservation, raising over $1,000,000 for bird protection since it launched.

The Birdathon unites thousands of birders, conservationists, and people across Wisconsin who cherish our state's wildlife and natural wonders. Each spring individuals and organizations create teams to find as many bird species as possible in a single day, while raising funds to support priority bird conservation projects for Wisconsin birds.
