Mass Audubon's Largest Annual Fundraiser & Nature Celebration

For 40 years, Bird-a-thon has brought birders, nature-lovers, and families together to celebrate nature and raise funds that provide essential year-round support for Mass Audubon's conservation, nature education, and advocacy work.

No matter if you join for the fun of it or for the thrill of competition (or both!), every team member has the opportunity to enjoy birds while raising or donating essential funds for Mass Audubon.

Bird-a-thon 2024: May 10-11, 2024

This year, we're making it easier than ever to participate in Bird-a-thon! You can join one of 12 teams to take part in a series of birding competitions, you can fundraise for your team, you can donate to your favorite team, you can join a Bird-a-thon program, or all of the above!

Be sure to check out the latest guidelines and awards to see what's new this year.

Support a Birder or Participant

Birding may be over but you can still donate to your favorite team and/or on behalf of your favorite birder. If donating on behalf of a birder or participant, be sure to also select the team they are birding for—you can find team donation links below! Deadline for donations is May 31, 2024.
