Bird-a-thon, Mass Audubon’s annual birding competition takes place on May 13-14. Teams of birders will attempt to see (or hear) the most species in a 24-hour time span. At the same time, birders and “Bird-a-thon Boosters” are raising money to support wildlife sanctuaries and programs.

To kick-off Bird-a-thon and celebrate 100 Years of Mass Audubon Wildlife Sanctuaries, we compiled 100 great spots to bird on our wildlife sanctuaries. While we can’t make any promises, we offer a sampling of birds you may see at each location.

Love to bird or visit a sanctuary? Consider donating to a sanctuary team in honor of the 100th anniversary.
