What bird is that?

by Frank M. Chapman

Scrubby second growths undergrown with bushes, roadside borders of trees and bushes, and the brushy margins of woods are all resorts of the Chestnut-side. Here he attracts our attention by his rather loud, frequently uttered song, which strongly suggests that of the Yellow Warbler. The nest is built within a few feet of the ground and the white, brown-marked eggs are laid the latter part of May.

Dendroica castanea. [Case 8], Figs. 69, 70

The adult male is unmistakable; the female has chestnut on sides and crown, a grayish streaked back and white wing-bars; the young bird in the fall cannot, in the field, be certainly distinguished from the young Blackpoll, but has the underparts tinted with buff instead of with yellow. L. 5¾.

The Bay-breast is one of the rarer members of its family. Most of us know it only as a migrant passing northward in May and southward in September, when it may be found in woodlands associated with other migrating Warblers. Its song resembles that of the Black and White Warbler. Mrs. Farwell describes it as "a poor, weak, monotonous saw-filing note." The nest has been found in hemlocks 15-20 feet from the ground. The white eggs, finely marked with shades of brown, are laid in June.

BLACK-POLL WARBLER
Dendroica striata. [Case 8], Figs. 71, 72

In the spring, a black cap, white cheeks and a gray, black streaked back distinguish the male; a gray, black-streaked back, the female. In the fall, young and old are olive-green, streaked with black above; yellowish white below, and thus closely resembles the young Bay-breast. L. 5½.
