Mass Audubon’s Statewide Birding Competition!


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. At Camosse, we’ve been participating in & supporting this great event for almost a decade.

Whether 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.
