Genus

Members of the genus Strix are the wood owls. They are medium to large owls, having a large, rounded head and no ear-tufts. The comparatively large eyes range from yellow through to dark brown. Colouring is generally designed fro camouflage in woodland, and a number of the member of this genus have colour phases. There are 20 species scattered practically throughout the globe with the exception of Australasia, the South Pacific and Madagascar, where the genus Ninox takes its place. There being no clear generic differences between Strix and Ciccaba genera, and DNA evidence suggesting very close relationships, many authorities now merge the latter into the former.

Physical charateristics

It has a light brown facial disc surrounded with brown circles and with small white eye-brows. Below it is buff with brown barring.

Range

South America : Southeast. The Rusty-barred Owl is not very widespread, being found mainly in southern Brazil (where it is also known as the Brazilian Owl) and inland towards Paraguay and the north-easternmost part of Argentina

Habitat

It is found in both lowland and montane forest (to 2000 m). It appears to naturally occur at low densities, and is considered highly sensitive to disturbance

Reproduction

The breeding season for the Rusty-barred Owl is between the months of August and October. It nests in a tree hole. The incubation period is 29 days on average. The young leave the nest five weeks after birth, and become fully independent at approximately four months. Both parents help brooding the young, the male to a lesser extent. Clutch size is 2-3 eggs

Feeding habits

It feeds at night in the canopy on small birds, mammals and insects.

Conservation

This species is classified as Near Threatened because the population is suspected to be declining very rapidly owing to habitat loss.
The Rusty-barred Owl is one of only two members of the Strix family found only in South America. It is, like the other purely South American member of the genus, the Rufous-thighed Owl (Strix rufipes), a very elusive character, probably quite scarce, certainly little studied. Most details of its lifestyle and niche are obscure and it is thought likely that, when sufficient detail is known, these two smallish owls (about 350mm in length) may eventually be removed from the Strix genus and reclassified in a genus of their own.
