The Niaskauz ( Strix niasensis ) is a species from the family of the real owls (Strigidae). It occurs exclusively in Southeast Asia and is one of the very few island endemic species within the genus Strix . For a long time it was considered a subspecies of the Malay Owl . In more recent literature it is assumed that the Niaskauz forms a superspecies together with Malay Owl, Mountain Owl and Bartelskauz .
features
With a body size of about 35 centimeters, the Niaskauz is a rather medium-sized species within its genus. Feather ears are missing. The face veil is reddish brown to chestnut colored and surrounded by an inconspicuous and fuzzy dark border. The region around the eyes is black. The eyebrows are pale reddish-ocher in color. The head plumage is otherwise predominantly dark to black-brown. The throat is whitish. There is a wide, dark chestnut-colored band in the neck. The front breast is bright chestnut colored. The wings and tail are striped reddish and cream-colored. The underside of the body is cinnamon-colored with darker, brown horizontal stripes. The legs are feathered, the toes are just not feathered at the front. The eyes are dark brown.
It can be confused with the Malay Owl , whose face veil is more reddish and lacks the neck band. Like the mountain owl, it is also noticeably larger. The neck band of the barbed owl is ocher colored.
Distribution area
The range of the Niaskauz is limited to the island of Nias northwest of Sumatra. It is one of the few island endorsements within the Strix genus . A similarly limited distribution area can only be found in the great gray owl and the Sichuan owl . The Niaskauz is a resident bird. Its habitat are tropical forests of the lowlands.
Way of life
Almost nothing is known about the specific way of life of the Niaskauz. It is generally assumed that the way of life corresponds to that of the Malay Owl.
