A large vireo very similar to Red-eyed Vireo. Had a gray crown, whitish supercillium, dark line, and distinct black whiskers on either side of throat. Greenish above and whitish on the breast with yellow undertail coverts, belly and flanks.




Similar species:

Black-whiskered is most similar to Red-eyed and Yellow-green Vireos, but the distinct black whiskers are diagnostic for Black-whiskered, and though it appeared more yellow than other Red-eyed vireos I had seen that day it did not have yellow along the sides and into the cheeks like Yellow-green Vireo.

This is the first one I have seen in Louisiana, but I saw and banded several in Eastern Puerto Rico.
