Seven subspecies are currently recognized[1]:

This and almost all Screech Owls in the Americas have previously been considered to belong in the same genus (Otus) as the European and Asian Scops-Owls, but a reassignment to Megascops have been accepted by among other authorities, the American Ornithologists' Union.
