Strix hylophila (Rusty-barred Owl)

Wikipedia Abstract

The rusty-barred owl (Strix hylophila) is a species of owl distributed mainly in the south of Brazil (where it is known as the Brazilian owl) and further inland to Paraguay and the extreme northeast of Argentina.The rusty-barred owl is one of only a few members of the Strix genus to be found in South America. It is elusive and probably quite rare, and as a result has been little studied. The classification in the Strix genus is therefore probably only temporary, until more information can be gathered on the nature of the owl.
