Cerulean Warbler
Dendroica cerulea

The Cerulean Warbler is primarily a bird of old growth deciduous forest. It has recently expanded its breeding range into Massachusetts, but as of yet this range in the state is very restricted. Despite its recent colonization of Massachusetts, concern over this species' declining population at both regional and national levels is high.
