Description:	Red-eyed type vireo. Bright yellow undertail with paler yellow on the flanks and most of the underparts with yellow going onto the cheeks and neck. Dull white throat; dull white streak in middle of breast and belly. Dull white in vent area. The rest of the underparts were pale yellow. The back and wings were fairly bright yellowish-green with the wings perhaps a little duller. In the video, the yellow wing linings (underwing coverts) can be seen. The face pattern showed less contrasty than on Red-eyed Vireo. The white supercilium didn\'t contrast as strongly with the dark eyeline or the border of the gray cap. The lower border of the gray cap was not as dark as on a Red-eyed. The bill appeared longer and slightly thicker than that of a Red-eyed. The bill was dull horn colored. The eye was dark with reddish tones in some light. The only noticeable plumage difference between the two birds (Peveto and Johnsons Bayou birds) that I could see in the video is that the second bird had slightly more white on the underparts, but it still had a great deal of yellow.
Voice:	The bird vocalized a couple of times, but I would be hard pressed to describe how it differed from a Red-eyed.
Similar species:	The yellow on this birds was far beyond what would be on the bightest Red-eyed. The face pattern and back color also indicate Yellow-green, as do the yellow wing linings.
Photographs or tape recordings obtained?	Video submitted to LBRC.
Previous experience with this species:	I’ve seen once before in LA and several times in the neotropics.
Identification aids:	After observation - Sibley and Costa Rica guides
