Buff-crested Bustard
Lophotis gindiana
The buff-crested bustard is a medium-sized East African bird that can reach up to 60 cm (24 in) in height. Compared to other African bustards, this species is relatively small. Male buff-crested bustards weigh between 675 and 900 grams (24 and 32 oz). Mature males display a black stripe that extends from the throat to the breast. The male plumage is grey or buff, except for the black stripe and dark underside of the body. Most bustards of this family are sexually dimorphic; the male and female differ in plumage coloration and size. Voice: The bird is more often heard than seen. The vocalizations are described as powerful short whistles. During display, the males produce a series of accelerating loud whistles, or 'kri-kri-kri' calls, that slow down towards the end.
