The Rötelkauz ( Strix albitarsis ) is a kind from the family of authentics owl (Strigidae). It occurs exclusively in South America. It was previously placed in the genus Ciccaba , but in more recent literature it is included in the genus Strix .
features
With a body size of about 30 to 35 centimeters, the red owl is a medium-sized species within its genus. There are no feather ears . The face veil is reddish and turns black around the eyes; it also has pale, concentric lines and a gray border. The upper side of the body is dark brown with reddish brown spots and horizontal stripes, the underside is whitish with reddish and dark brown longitudinal and transverse stripes. The eyes are orange-yellow.
It can be confused with the white-throated screech owl , which is smaller and darker and has a noticeable white throat. The zebra owl is significantly darker and has plumage with fine white lines. The South American mottled owl has brown eyes and lacks longitudinal and horizontal stripes on the underside of the body.
Distribution area and habitat
The distribution area extends in a narrow band from Venezuela, Colombia and Ecuador to the extreme northwest of Peru and from there along the eastern slopes of the Andes to the south of Bolivia. The red owl is a resident bird that lives in dense mountain and cloud forests at altitudes between 1,700 and 3,700 meters.
Way of life
The red owl is a crepuscular and nocturnal species that very little is known about. The ornithologists Claus König and Friedhelm Weick describe it in their monograph published in 2008 as almost completely unknown (" virtually unknown "). It is believed to feed on small mammals and insects. Nothing is known about reproductive biology. However, young birds have been observed in Venezuela in August and in Colombia in June.
Systematics
The Rötelkauz was formerly jointly with the live also in the tropical regions of South America black-and-white owl ( Strix nigrolineata ), the black-banded owl ( Strix huhula ), the South-mottled owl and the African African tawny owl ( Strix woodfordii ) into a separate genus Ciccaba but found dissolved and merged with the genus Strix .
