Warbler, Bay-breasted bird picturesBAY-BREASTED WARBLER
660. Dendroica castanea. 5 1/2 inches

Male, with crown, throat, and sides rich chestnut; female, paler; young and adults in winter, greenish above, streaked with black and with a trace of chestnut on the flanks.

These Warblers are only locally abundant during migrations, while in eastern New England they are rare.

They are active insect hunters, darting rapidly about the tree tops or, less often, in brush; their habits most nearly resemble those of the Chestnut-sided Warbler.

Song. - A low, liquid warble.

Nest. - At low elevations in trees in swampy woods; compact, cup-shaped structures made of fine shreds of bark, rootlets, and grass; eggs bluish white, finely specked around the large end with reddish brown (.70 x .50).

Range. - Eastern N.A., breeding from the northern edge of the U.S. northward; winters south of the U.S.
