Strix rufipes

Thought probably most closely related to S. hylophila and S. chacoensis, all having vocalizations very different from other Strix, and possibly generically distinct. Usually considered to include S. chacoensis as a race, but differs in plumage, morphology and voice. Race sanborni described from single immature specimen, perhaps not acceptable. Two subspecies tentatively recognized.

  • S. r. rufipes P. P. King, 1827 – from C Chile and extreme WC Argentina S to Tierra del Fuego.
  • S. r. sanborni Wheeler, 1938 – Chiloe I, off SC Chile.
