Go birding for a cause!

When you join the Great Wisconsin Birdathon, you're participating in the largest fundraiser for bird conservation in Wisconsin. Since 2012, the Birdathon has raised more than $800,000 and engaged thousands of individuals in protecting our state's most threatened and endangered species. This year, we invite you to join us in raising another $100,000+ for our feathered friends!

Funds raised through the Great Wisconsin Birdathon go directly to the Natural Resources Foundation's Bird Protection Fund, which supports Wisconsin's highest priority bird conservation projects. Your birding will make a difference!

Are you ready to make your birds count?

How it works

The Great Wisconsin Birdathon engages individuals and communities to raise support and awareness for bird conservation in Wisconsin. Anyone can participate by donating to a team or forming a team to count birds. It's like a walk-a-thon style fundraiser, but instead of logging miles, our participants are logging bird sightings! 🦅

Birdathon teams can participate any day between April 15th to June 15th. While most teams choose to compete over a 24-hour period, many teams opt to bird over the course of a weekend, a week, or even the entirety of the Birdathon!

How, when, and where you bird is up to you. Whether you're backyard birding over the course of a week or planning a route to hit all your favorite hotspots in one day, it all counts! Participation is free and all skill levels are welcome to join! From beginning birders to seasoned scouters, the Great Wisconsin Birdathon is for everyone.

Every Dollar Makes a Difference

Connecticut Warblers

There is little known about this warbler due to its seclusive behavior and remote habitat. Previous Birdathoners have funded projects that aim to support awareness and research for this rapidly declining bird. Photo by Brian Collins


Your donation goes to our Bird Protection Fund, making a difference for Wisconsin's imperiled species, like Connecticut Warblers, Whooping Cranes, Piping Plovers, and more.
