Bird-a-thon • May 12-13, 2023
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.
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.
The Bird-a-thon planning team is looking for sponsors for Bird-a-thon 2023. Learn more about sponsorship opportunities >
