RED-EYED VIREO.
624. Vireosylva olivacea. 6 inches.
One of the most common of the family throughout its range, from the eastern slope of the Rockies over the United States. Wherever they may be found, their song is heard continuously during the day, from early morning until late in the evening, it consisting only of two or three notes, first a rising inflection, then a falling, and repeated over and over, even while they are feeding. The nests are placed within a few feet of the ground on an overhanging limb, suspended from a fork, and made of strips of bark, plant fiber and often with pieces of string and paper included in its construction. Three or four eggs are white, specked sparingly with brown (.85 × .55). This is one of the favorite nests in which the Cowbird deposits its eggs.
