Although major vocal differences between Middle American and South American races in one study#R suggested at least two species involved, that analysis included only two vocalization types, did not take account of all differences among races, and omitted populations from W of Andes; recent analysis (unpublished data) found that some races are vocally less similar to others in their group than to races placed in a different group, while birds W of Andes are vocally much closer to Middle American group; much further work needed. Birds of Tabasco (SE Mexico) previously separated as race mexicanus, but inseparable from flammulatus. Original spelling of race citreopyga invariable#R (contra HBW). Twelve subspecies recognized.
