Karoo chat Karoo chat The Karoo chat ("Emarginata schlegelii") is a small passerine bird of the Old World flycatcher family Muscicapidae. It is a common resident breeder in southwesternmost Angola, western Namibia and western South Africa. Its habitat is Karoo and desert scrub in the south, extending to the escarpment zone in the north. The first formal description of the Karoo chat was by the Swedish naturalist Johan August Wahlberg in 1855 under the binomial name "Erithacus schlegelii". The species was subsequently placed in the genus "Cercomela" introduced by Charles Lucien Bonaparte in 1856. It was moved to its current genus, "Emarginata",
Semi-arid climate Semi-arid climate A semi-arid climate or steppe climate is the climate of a region that receives precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. A more precise definition is given by the Köppen climate classification, which treats steppe climates ("BSk" and "BSh") as intermediates between desert climates (BW) and humid climates in ecological characteristics and agricultural potential. Semi-arid climates tend to support short or scrubby vegetation and are usually dominated by either grasses or shrubs. To
