Its plumage is a blend of dark reddish-brown with buff markings, and its legs are covered in soft, buffy feathers.

Distribution and Habitat

This owl inhabits moist, old-growth forests characterized by a closed canopy and a dense understory. It can also be found in older secondary forests and semi-open woodland environments. Its range extends from approximately Valparaíso Province in Chile and Mendoza Province in Argentina, southward to the very tip of Tierra del Fuego. The species occupies elevations from sea level up to at least 2,000 meters.

Behavior and Diet

The rufous-legged owl is primarily nocturnal, typically hunting from a perch. Its diet largely consists of small arboreal mammals. While birds, amphibians, and insects are also consumed, they constitute a minor part of its food intake.

Reproduction

Information regarding the breeding habits of the rufous-legged owl is not extensively documented. It is believed to begin laying eggs around October, with clutch sizes ranging from one to three eggs. Nests are usually located in tree cavities, either natural or previously excavated by woodpeckers. There are also occasional reports of them using old raptor nests, and a possibility of ground nesting has been suggested.

Conservation Status

The International Union for Conservation of Nature (IUCN) has assessed the rufous-legged owl as Least Concern. The species benefits from its presence in several protected areas across its range. However, outside of these reserves, the owl may face threats from the logging of its essential mature forest habitat.
