The Ogadenlark ( Mirafra gilletti ) is a species from the lark family. It is a species widespread in the east of the African continent. It is significantly smaller than a skylark , but has a stronger beak than this. There are several subspecies. The Degodilerche , which was temporarily classified as an independent species ( Mirafra degodiensis ), is again listed as a subspecies of the Ogadenlark.
The stock situation of the Ogaden Lark is classified as safe ( least concern ).
features
The Ogadenlche reaches a body length of 14 to 16 centimeters, of which 7.7 to 9 centimeters are on the tail. The beak has a length of 1.6 to 1.83 centimeters measured from the skull. They weigh between 20.3 and 24.8 grams. There is no noticeable gender dimorphism .
The Ogadenlark has a reddish head, the vertex has fine dark brown dots. The cheeks and ear covers, on the other hand, are finely dashed in white. The stripe above the eyes is whitish. The nape, the back of the neck and the sides of the neck are more brownish pinnate, the individual feathers have yellowish brown to whitish fringes. The coat and back are brown with a slight reddish tone, the individual feathers have black-brown centers. The rump and the upper tail-coverts are gray-brown with light hems.
The chin and throat are white, the chest is isabel-colored with dark dashed lines, the rest of the underside of the body is whitish and becomes darker towards the lower tail-coverts. The hand and arm wings are dark brown. The tail feathers are also dark brown. The middle pair of control springs is narrowly lined with reddish brown. The upper beak is brown, the lower beak a little lighter.
Possible confusion
There are two species of lark with which it can be confused: the steppe lark and the pale-breasted lark in the distribution area of the Ogadenlark .
The Ogadenlark differs from the steppe lark by its darker body surface, which is more clearly dashed and less reddish than the steppe lark. The steppe lark also has a white to sand-colored outer flag on the outermost control feather. The pale-breasted lark has a gray crown and a light face with no further markings.
Subspecies and their distribution areas
There are three subspecies for the Ogaden Lark:
- M. g. gilletti - Sharpe , 1895 : Occurrence in eastern Ethiopia and north-western Somalia.
- Degodilerche ( M. g. Degodiensis ) - Érard , 1976 : Occurrence in the southeast of Ethiopia
- M. g. arorihensis - Érard, 1976 : Occurrence from central Somalia to the northeast of Kenya.
The Ogaden Lark is a resident bird in its entire range .
habitat
The Ogadenlark is preferred in open savannahs. It prefers places with hard and stony soils. In Somalia it also occurs in lightly forested steppe areas. The altitude distribution ranges from 1000 to 1500 meters.
Way of life
The Ogadenlche eats arthropods and various seeds.
The Ogadenlark sings its song both from tree tops and during the singing flight. When singing, it rises at least 100 meters and then circles continuously while singing for about 10 minutes before dropping again steeply to the earth.
Like all larks, the Ogadenlark is a ground breeder. The nest is cup-shaped and is partially covered with grass. The clutch usually consists of three eggs.
