Description:

A Red-eyed type vireo, similar in most regards to that species. This bird was much brighter than the bird found on 5/16 by Broussard; whereas the dullness of that bird made Broussard wonder about his ID until he got a got look, this bird left no doubt.

 

Overall, the birds were similar, so I’ll largely copy from the other record:

 

Crown dull gray, bordered weakly on sides slightly darker gray—but not as pronounced as on Red-eyed. Sides of face pale dingy gray except for weak dusky eyeline running from lores back to nape or hindcrown and yellowish wash extending onto rear of auriculars from the sides of the neck. Chin and throat whitish. Irides red or reddish-brown. Bill pale, horn perhaps. Back green or olive-green, fairly bright in sunlight, perhaps with a yellowish-green tint. Wings slightly darker, coverts and flight feathers margined green as in mantle. Tail appeared equal in color to upperparts. The flanks and breast sides were washed in an even, rich bright yellow that contrasted noticeably with the clean white of the chin, throat, and central underparts. The white of the chin and throat extended centrally down to the vent,  remaining clear white throughout. On this bird, the ventral white was much brighter, and seemed much broader than on the Peveto bird. The yellow extended evenly along the flanks except at the upper breast, where it extended in towards the center and was only narrowly separated by the white central stripe which was at its thinnest in this area. Legs grayish or bluish gray.

Voice:

Muth and Wallace heard it sing initially, but I don’t know if it sang while we were there.
