The Magellanic Horned Owl is distributed from Peru to Tierra del Fuego mainly in Chile but also in adjacent western Argentina. It is found in a variety of habitats but requires open country for hunting and cliffs, trees or shrubs for roosting.

It is considered a sub-species of Great Horned Owl B. virginianus by Howard & Moore 2013 however many authorities such as Konig et al and Mikkola treat it as a species on the basis of differences in vocalization, appearance and DNA.

Compared to the nominate Great Horned Owl it is smaller with smaller "horns" and narrower barring on the underparts.

Photos 1 to 3 were taken at 13:00 hours in Tierra del Fuego.
