The Usamabara eagle owl ( Bubo vosseleri ) is a species from the family of real owls. It occurs only in a small area in East Africa. In older literature it is occasionally listed as a subspecies of the Guinea eagle owl . However, the two species do not have a coherent range and differ in their body size, their reputation repertoire and their plumage.

features

The Usambara eagle owl is significantly larger than the Guinea eagle owl and reaches a body length of 45 to 48 centimeters. It is darker on the upper side of the body and has a reddish face veil that is surrounded by black feathers. The front breast has a dense brown-black pattern of spots. The rest of the underside of the body is irregularly striped across and also has very narrow, dark vertical stripes. The feather ears are brown and short. The eyes are dark orange-brown. There is also a similarity with the Fleckenuhu , but this one has more conspicuous feather ears and yellow eyes. The gray owl, on the other hand, is grayer and more densely striped on the underside of the body.

distribution and habitat

The distribution area of ​​the Usambara eagle owl is very small: it is limited to the Usambara and Uluguru mountain ranges in northeastern Tanzania. It may also be found in the Nguru Mountains in this region. It colonizes evergreen mountain forests, forest edges and plantations at altitudes between 900 and 1,500 meters. He is basically a resident. Non-breeding Usambara Eagle Owls occasionally move to lower valleys in cold weather. They then also occur at heights of 200 meters.

Way of life

The habits of the Usambara Eagle Owl have not yet been adequately investigated. However, it is very likely that its lifestyle is largely similar to that of the Guinea Eagle Owl. The food spectrum presumably includes small mammals and birds as well as reptiles and spiders. Reproductive biology has not yet been conclusively researched either. Clutches were found in October, December, January and February. A young bird that was not yet able to fly was observed in April.
