In need of taxonomic study; races may constitute more than one species, while some may represent only clinal plumage variation. Revised interface between nominate and race elegans is based on preliminary analysis of vocalizations. In addition, elegans intergrades with proposed race napensis (E Ecuador, NE Peru), with no clear boundary between them; these two best synonymized, pending further review. Seven subspecies recognized.
