Clearly part of the Red-eyed Vireo (Vireo olivaceus) superspecies, the Yellow-green Vireo is remarkable for being the only Middle American passerine that wholly vacates its breeding areas in winter, at which season it ranges across western South America, mainly east of Andes, as far south as northern Bolivia. During the breeding season, it occurs from southernmost Texas, in the Rio Grande delta south at least as far as central Panama. Compared to the other four members of the superspecies, the Yellow-green Vireo is clearly distinguished by its bright yellow ventral region and yellowish flanks, as well as its different voice.
