Although groupings of subspecies here have been suggested as indicative of species-level division on basis mainly of differences in song (song of forms W of Andes and into NW Venezuela ending in trill, songs E of Andes accelerating far less), these vocal differences appear, despite earlier statements (HBW), not to correlate with differences in plumage found in recent examination of specimens. Plumage differences in populations of Middle America and the Pacific slope appear to be clinal, and recognition of races may not be warranted; further study required. Plumage and vocal differences of races E of Andes more substantial, but careful analysis required to determine extent of intergradation and constancy of characters. Ten subspecies recognized.
