The Chaco owl (Strix chacoensis) inhabits the Gran Chaco, a region in Paraguay characterized by low rainfall. The species is found there in hilly, rolling, and flat terrain with a wide variety of forest types, both dense and semi-open. Found in the dry, hilly, landscapes of Argentina, Bolivia, and Paraguay, it has a characteristic round head, a whitish throat and no ear tufts – and builds its nests in or under thorny bushes and holes in trees.
