Recently described race hernandezi suggested to represent a separate species#R: differs morphologically from nominate solely by its whitish, less buffy tinge on breast and belly (1); slightly paler, greyer flanks, wings and tail (1); slightly longer bill (effect size for males based on published data#R 1.35, ns) and wing (1.86, score 1); slightly shorter tail (1.3, score 1); possibly different social system (further research needed; ns); reportedly different voice#R, but one online recording sounds identical to that of nominate (further research needed; ns); moreover, genetically the two taxa are relatively close#R. Two subspecies recognized.
