How it works

Individuals form teams of birdwatchers and select a date between April 15th and June 15th. The team then commits to counting as many unique bird species as possible in that 24-hour period. Next, the team sets a fundraising goal as well as a goal for how many species of bird they hope to see. Then the team collects pledges and donations from friends, family, and community members. Donors can pledge per bird or just make a contribution to the team.

Teams can bird anywhere—a backyard, local park, or venture into the field in any of Wisconsin’s beautiful landscapes. Some teams even choose to split up to cover more area in the hopes of seeing more birds, while others stick together to enjoy the shared experience.

Both novice and expert birders can have fun and make a difference in protecting birds. The funds raised through the Great Wisconsin Birdathon support Bird Protection Fund priority projects.

Environmental and conservation organizations can also use the Great Wisconsin Birdathon to fundraise for their own projects. The Natural Resources Foundation will split the funds raised with 50 percent of the team’s earnings going back to that organization and 50 percent going to the Bird Protection Fund. In 2016, 22 organizations and Bird Cities took home more than $12,000 from the Great Wisconsin Birdathon.



We’d like to express our gratitude to our 2017 sponsors. Their support helped us reach well beyond our $75,000 goal!
