Subspecies
Considered by some authors to form superspecies with Ferruginous Pygmy-Owl (Glaucidium brasilianum), Tucuman Pygmy-Owl (Glaucidium tucumanum) and Peruvian Pygmy-Owl (Glaucidium peruanum). Sometimes treated as subspecies of Ferruginous Pygmy-Owl (Glaucidium brasilianum), but apparently some subtle differences in vocalizations exist. Recently shown to differ also in DNA.
