Support a Mass Audubon sanctuary or program by donating to Bird-a-thon.

Your Bird-a-thon donation is greatly appreciated and helps to protect the nature of Massachusetts for people and wildlife. Donate to an individual, donate to a team, or make a general Bird-a-thon donation. To donate offline, please download and return the Bird-a-thon mail-in donation form and send it with payment to your chosen sanctuary or program.

Join a Team

There are multiple ways to be a part of a Bird-a-thon team!

You can join a team as an Official Birder or as a Bird-a-thon Booster—both help raise money for your favorite sanctuary or program!

An Official Birder’s species checklist counts towards their team’s total, while Bird-a-thon Boosters bird for fun, do their own nature-based activity, or participate solely through fundraising. If you'd like to participate as an Official Birder, join a team first and then contact the Team Captain directly.

About Bird-a-thon

Bird-a-thon, Mass Audubon’s largest fundraiser, brings together supporters from across the state to raise essential funds for nature conservation, education, and advocacy—and to compete in an exciting team birding competition. Each year, more than 800 birders work with their team members to see, hear, and identify as many bird species as possible in a 24-hour period. Team members and other supporters raise money for Mass Audubon sanctuaries and programs in honor of their participation. View last year's results >

Since Bird-a-thon began in 1983, thousands of dedicated supporters and team members have raised over $3 million for Mass Audubon, its sanctuaries, and its programs across the state.
