bar of two to four notes warbled in rather full voice, then a short rest, and 

 a similar strain repeated. One might imagine he said, as has already been 

 written, " Here I am; look here; in the tree top; do you see me; way up here; 

 in the tree top? " Or, " See me; up here; in the tree," over and over again. 



In habits, this bird, like most of the family, is less nervous than the 

 warblers. He flits less, but sits quietly in the tree, peering about beneath 

 the leaves, and hops from twig to twig in search of smooth caterpillars, 

 beetles and other insects. 



The Red-eye's nest is suspended from a forked twig in a bush or the 

 low limb of a tree, from 5 to 10 feet from the ground. It is basket-shaped, 

 woven of grasses and strips of bark and pine needles, lined with finer strips 

 and needles. The outside is ornamented with spiders' webs and nests, 

 occasionally with bunches of other cottony substances. The eggs are 

 usually 3 or 4 in number, elongated oval in shape, white in ground color, 

 sparingly spotted with black, umber and reddish brown. They average 

 .82 by .53 inches in dimensions. The Red-eye is very commonly parasitized 

 by the Cowbird and usually succeeds in rearing its own young only on 

 a second attempt made in midsummer.

 vireo, but the whitish superciliary line and the dusky line through the eye 

 more conspicuous, almost as in the Red-eyed vireo; under parts noticeably 

 washed with sulphur yellow, the breast decidedly yellow, but the throat 

 and the center of the abdomen nearly white. This species has no apparent 

 spurious quill in front of the first primary.
