BLACK-POLL WARBLER
661. Dendroica striata. 5½ inches
Whole crown black; female, without black cap, greenish gray above streaked with black; young paler than the female.
These birds are one of the latest of the migrants to arrive, reaching northern United States about the last of May, but coming in such numbers that they are found everywhere. While their plumage somewhat resembles that of the Black and White Warbler, their habits are entirely different.
Song.—A high-pitched, hissing whistle similar to that of the [Black and White Warbler] but uttered more deliberately and with an instant’s pause between each note.
Nest.—At low elevations in thick coniferous trees; made of slender twigs, rootlets and lichens, lined with hair or feathers; eggs whitish, thickly spotted with brown (.75 × .52).
Range.—Eastern N. A., breeding from northern New England, Minnesota and Wyoming north to the Arctic regions; winters south of the United States.
