Bubo magellanicus (Lesser Horned Owl; Magellanic Horned Owl)

Synonyms: Strix magellanicus

Wikipedia Abstract

The lesser horned owl or Magellanic horned owl (Bubo magellanicus) is a large owl of the genus Bubo found in southern South America, extending north to the central Andes. It has traditionally been classified as a subspecies of the great horned owl (Bubo virginianus), but is now frequently treated as a separate species based on differences in voice and size and because of the genetic distance between the two. The deep hooting call consists of a double-note followed by a loud, vibrating note. The bird's local name tucúquere is imitative of the call.
