See D. glauca. Some races of present species weakly differentiated; a slightly paler specimen of saturata from El Chaco, on E slope in Ecuador, is perhaps intermediate between that race and media. Populations from C & W Andes of Colombia and adjacent NW Ecuador (currently placed in saturata) have been suggested as belonging to an as yet unnamed race, and populations from most of Ecuadorian range of media (except SW Ecuador) may represent an additional undescribed race; further study required. Race erroneously named as intermedia in HBW was already suggested as perhaps not meriting recognition, and that population is now returned to media; as a junior primary homonym, name intermedia is permanently invalid. Six subspecies tentatively recognized.
