Subspecies
Although locally abundant, not described until 1981. Old records of Magellanic Steamerduck (Tachyeres pteneres) on Chubut coast presumably refer to this species. Often considered to form superspecies with Magellanic Steamerduck (Tachyeres pteneres) and Falkland Steamerduck (Tachyeres brachypterus).
