CONNECTICUT WARBLER. 
578. Oporornis agilis. 51 inches. 
Male with a bluish slate-colored head; eye ring white 
and completely encircling the eye; female with a saffron- 
colored head. 
In the United States we find this Warbler only in 
spring and fall migrations. They appear to be much 
more rare in the spring than in the fall; while I have 
seen perhaps a hundred in the fall I have never seen 
but one in spring. They frequent wild tangled thickets, 
such as you often find Maryland Yellow-throats in. As 
they do most of their feeding upon the ground and _re- 
main in the depths of the thickets, they are rarely seen 
unless attention is drawn to them. 
Song.—Somewhat like that of the Maryland Yellow- 
throat; call, a sharp, metallic “peenk.” 
Nest.—In thickets or clumps of briars, either on the 
ground or just above it; made of strips of bark and 
skeletons of leaves, lined with hair; eggs whitish spar- 
ingly specked at the large end with brown (.75 x .56). 
Range.—Hastern N. A., breeding north of the U. S.; 
winters in northern South America.
