J. F. Gmelin, 1789,
MtDNA study revealed weak support for relationship between present species and N. aethereus#R. Validity of subspecies guatemalensis not universally accepted#R, and supposed differences may represent merely extremes in broad geographical size trends and individual plumage variation. No taxonomically clear variation in most of extensive range, despite great genetic divergence on opposite sides of Andes and possible population disjunction between Amazonia and Atlantic Forest; may contain undescribed “cryptic” taxa. Two subspecies tentatively recognized.
