Identification & Behavior: ~12-14 cm (4.7-5.5 in). The Red-eyed Vireo has yellow-olive upperparts and tail. The underparts are generally whitish with yellow on the sides of the breast. It has a gray cap bordered by blackish stripes. It has white superciliary, dusky lores and an iris that vary from red to brown. All forms have yellow undertail coverts. The Red-eyed Vireo forages in the canopy and sub-canopy of the forest in Amazonia, semi-deciduous forest, and montane forest and Andean scrub. It is very similar to the Yellow-Green Vireo but is distinguished by smaller size, less yellow on the underparts, and little or no black bordering on the crown. Also, see Brown-capped Vireo.
