Red-eyed Vireo

Vireo olivaceus - Red iris, prominent eye stripe, and blue-gray cap distinguish this bird from all others. Immature has a brown iris. It is told by its bright yellow sides and undertail coverts and less distinct eye stripe. Immature Red-eyed has buffy undertail parts. Song is robin-like but phrases are separated by brief pauses; the song continues for many minutes without a long break, 35-70/min.
