Bird-a-thon

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

This year's Bird-a-thon will take place on May 10-11, 2024. Stay tuned for details!
