Breeding Bird Atlas 2
More than 650 volunteer citizen scientists worked more than 43,000 hours from 2007-2011 to complete the new Massachusetts Breeding Bird Atlas 2. This work gives us a rare glimpse in the detailed changes in our breeding birdlife, and tells the story of each species history in the state. Join us and explore the Black-capped Chickadee, the Bald Eagle, the Ruby-throated Hummingbird, the Great Horned Owl, and more than 200 other species.
The results of this work are valuable treasure for the future of bird conservation in Massachusetts. They give us a clear picture of the range of all species that breed in the Commonwealth, and when compared to Atlas 1 they give us clear proof of the changes in our breeding birdlife since 1979.

Some of our most familiar and beloved birds—such as the American Kestrel, Eastern Meadowlark, and Baltimore Oriole—are not as abundant as they once were across Massachusetts.
We need your support to continue important research to help these bird populations.
