Bird-a-thon • May 12-13, 2023

Mass Audubon's Largest Annual Fundraiser & Nature Celebration

Bird-a-thon 2023 Banner

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.

Rally your friends and family to join you or support your fundraising efforts and go birding with us May 12-13!

Registration will open late March.
