Although this shy bird is difficult to spot, you can distinguish the vireo from the warbler by its olive green haberdashery. The word "vireo" connotes 'green'. Another difference is his broader bill, which is slightly hooked at the end. The White-eyed Vireo has other distinctive markings, such as yellow flanks and white wing bars.
Eye is dark.
The White-eyed Vireo breeds in swampy thickets and hillsides among blueberry bushes and briar tangles, from the Midwest eastward to Central New England and New York, and south to Florida and east Texas.
Calls or song.
The White-eyed Vireo, although bashful, makes up for his elusiveness by lound and complex vocalization. Each individual bird references a song book of a dozen or more unique sounds. Most begin and end with a short "chip", for example: "chip a wheeoo-chip".
Population and distribution.
Mid and eastern United States. Winters on the Gulf Coast
The White-eyed Vireo builds a nest of bark and grass, lined with spider silk, moss and lichen in any thick undergrowth. She lays 4 white eggs, spotted brown. Cowbirds frequently replace these eggs with their own, which the Vireo incubates, subsequently nurtureing the offspring.
