Eastern Bluebird
Sialia sialis

The very widespread breeding distribution seen in the Eastern Bluebird in Massachusetts today is, in large part, the result of considerable support received by concerned citizens who, for more than half a century, erected large numbers of nest boxes across the state and helped save the species from near-extirpation.
