Description: Hindquarters of this distinctive antelope appear to be slightly higher than the shoulders. A dark red-brown band along the flanks separates fawn-brown upper parts from the white under parts. The head is white with a brown stripe running through the eye to the corner of the upper lip. A large white patch on the rump is bordered by a brown stripe. There is a long-haired, white dorsal crest extending from the midpoint of the back to the rump; this is normally seen only when the crest is extended for example during “pronking”. The pronk is a jump performed with stiff legs accompanied by arching of the back. The tail is white with a tuft of black hairs at the tip.
