Because Nature Needs Our Focus

Bird-a-thon logo

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 birding competition. Each year, over 20 teams compete to spot 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.

Help Us Reach Our Goal!


Since the event 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. 


Join a Team

Participate in this year's event by joining a team as an Official Birder or a Bird-a-thon Booster and help raise money for your favorite sanctuary or program! Fundraisers can bird for fun, do their own nature-focused activity, or simply support the team from home. If you'd like to be included on a team’s Official Birders roster, contact the team captain directly.

To sign up, start by joining a team on the fundraising website.
