RED-EYED VIREO. 
624. Vireosylva olivacea. 6 inches. 
Crown slaty gray with a black border; white stripe 
above eye; eye reddish brown. 
Throughout the United States this is one of the most 
abundant of the family. All through the spring and 
summer months their warble is heard from woodland 
and roadside, often becoming so monotonous as to be 
irritating. Oftentimes during the spring migrations of 
Warblers, Vireos are so numerous and singing so lustily 
that it is impossible to hear or distinguish the songs 
of any of the smaller birds. 
Song.—Delivered in parts with intermission of a few 
seconds between, from morning until night; a short 
varied warble; call, a petulant mew. 
Nest.—A basket woven of strips of bark and fibres, 
and often with pieces of newspaper worked in, lined 
with fine grass; eggs white with a few blackish-brown 
specks on the large end (.85 x .55). 
Range.—U. S. east of the Rockies, breeding from 
the Gulf to Labrador and Manitcba; winters in Central 
America.
