How it works

The Great Wisconsin Birdathon is Wisconsin’s largest fundraiser for bird conservation. It's like a walk-a-thon style fundraiser, but instead of logging miles, our participants are logging bird sightings! Each year, bird enthusiasts from across the state raise support and awareness for bird conservation by forming a team or donating to a team.

Birdathon teams can participate any day from April 15th to June 15th, and donations are accepted from March 15th to June 30th. Participation is free and all skill levels are welcome to join. 🦅

How, when, and where you bird is up to you. 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! Teams can bird anywhere in Wisconsin - a backyard, a local park, or a route to hit all their favorite birding hot spots. Both novice and expert birders can have fun and make a difference in protecting birds - the Birdathon is for everyone!

Donate #ForTheBirds

Online and check donations will be accepted from March 15 through June 30.

Donations go to the Natural Resources Foundation of Wisconsin's Bird Protection Fund. This fund provides critical support for high priority bird conservation projects that benefit Wisconsin's birds throughout their lifecycles. That means we can support birds on their breeding grounds here in Wisconsin, all the way to their migratory habitat in Central and South America!

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 the Natural Resources Foundation of Wisconsin's Bird Protection Fund, making a difference for Wisconsin's imperiled species, like Connecticut Warblers, Whooping Cranes, Bobolinks, and more.
