ABSTRACT
Eight of the 22 species occur in Kenya where all but one, again the Arabian Bustard, are breeding residents. All species make local movements. Distribution of breeding records tends to reflect observer frequency. Hartlaub's Bustard forms a superspecies with the Black-bellied Bustard (Sn). Hartlaub's Bustard is thought to be resident. The population in northeastern (NE) Uganda has been considered isolated, but this may not be the case in view of the probable breeding in 37C. The Black-bellied Bustard is a commoner bird than Hartlaub's Bustard and, in addition to grassland, also frequents areas with bush and trees, including open woodland. Sn mentions possible competition with the larger Kori Bustard in S Africa, but there are no records of that species in Denham's former squares W of the rift. Wanderers also move southwest into moist subhumid country on the NE periphery of the C highlands, and records in 39A 51BD are adjacent to the range of the closely related Denham's Bustard.
