none

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.
