Nest.—Of leaves and strips of bark, lined with fine grasses; on the ground in clumps of weeds or blackberry vines; eggs white, sparingly spotted around the large end with rufous (65. × .50).
Range.—Eastern U. S., breeding north to southern Connecticut and Wisconsin; winters in the tropics.
Hybrids.—Lawrence Warbler, which is a hybrid between this species and the next; it has the general plumage of this species with the black ear patches and throat of the [Golden-winged Warbler]. It is found chiefly in southwestern Connecticut and New York.
GOLDEN-WINGED WARBLER
642. Vermivora 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. It seems to prefer low ridges and side hills covered with small bushes.
Song.—A buzzing “zwee-ze-ze.”
