Position in the genus Eremopterix

The position of the brown saddle plate within the genus Eremopterix has not yet been clarified. Some authors think it is conceivable that the brown saddle plate forms a super species with the white- fronted lark and the nun lark . Other authors are of the opinion that the brown and gray teller is a super species.

Distribution area and habitat

Distribution area of ​​the Braunscheitellerche

The brown saddle plate occurs from the extreme northeast of Uganda, western Kenya to Tanzania, the extreme north of Zambia, Rwanda and northern Malawi. Outside of the breeding season, they migrate nomadically in their area of ​​distribution. You also occasionally reach the south of Malawi.

The habitat of the brown cider are savannahs with short-growing grass vegetation and bare sandy areas. To the north-east of Lake Victoria, the brown pan is very common and occurs there at altitudes up to a maximum of 1,800 meters. In Malawi, on the other hand, it is usually only found at altitudes below 900 meters. It is also found there in gardens, on agricultural areas, on embankments along roads and on airfields.

Way of life

Brown side plates mainly eat grass seeds, while insects do not play such a big role in their diet. They are also observed in small groups during the breeding season. The courtship takes place mainly on the ground, but occasionally also on thick branches.

The breeding season falls in the north of the distribution area in the period February and July and is therefore in the rainy season. In the central and southern part of the distribution area, however, they breed in the dry season and thus in the period from April to August. Like all larks, the brown stone plate is also a ground breeder. The nest, which is typical for larks, is built in a self-paved hollow and is not overarched by grass. The clutch consists of two to three eggs. An egg has a fresh full weight of 1.42 grams.
