What is the Breeding Bird Atlas?

From 1974 to 1979, Mass Audubon, with the help of hundreds of birders throughout the state, collected data on all of the breeding birds in Massachusetts, and compiled that data into the first Massachusetts Breeding Bird Atlas.

Now, 30 years later, thanks to the success of our latest Breeding Bird Atlas project (which involved 600 people over five years), Mass Audubon has created the Breeding Bird Atlas 2 (BBA2).

BBA2 is published online, where you have access to detailed species accounts, distribution maps, and beautiful illustrations for each of the 200-plus bird species known to breed in the Commonwealth.

BBA1 and BBA2 have played a critical role in helping us understand the bird population and distribution trends we’ve documented here in The State of the Birds.
