642. Helminthophila chrysoptera. 5 inches.

Crown and two large wing bars yellow; throat and ear patches black; rest of plumage gray and white; female with less black.

The distribution of this beautiful Warbler is about the same as that of the last, with which it seems to have many habits in common. They seem to prefer low ridges and side hills covered with small bushes.

Song. - A slowly chanted "chee, chee."

Nest. - Of leaves, rootlets, strips of bark and grass; located near the ground in small bushes after the style of the Chestnut-sided Warbler, but the nest does not resemble that of the latter bird; eggs white with brown specks (.62 x .48).

Range. - Eastern U. S., breeding north to Connecticut and Michigan; winters in Central America.

Hybrid. - Brewster Warbler is a hybrid between this species and the last. It resembles the Golden-winged Warbler without the black, but with a yellow patch on the breast and the black line of the Blue-wing through the eye.
