savile's bustard Lophotis savilei

Fairly small bustard of dry country. The male has a buff crest that is usually hidden, and both sexes have a black belly. In flight, shows a black outer wing and brown inner wing separated by a white line. Found in dry savanna and thornscrub habitat. The distinctive vocalization is a ringing introductory note followed by a quick series of whistles. Similar to male Black-bellied Bustard, but smaller, and lacks a black line along the throat.
