Either of two species of swift, slender antelope (genus Alcelaphus) found in herds on open plains and scrublands of sub-Saharan Africa. They often mingle with herds of other antelope or zebras. Hartebeests stand about 4 ft (1.2 m) tall at the shoulder, and the back slopes downward from heavy forequarters to narrow hindquarters. The long face is accentuated, in both sexes, by ringed, lyre-shaped horns united at the base. The red hartebeest is pale reddish brown with a lighter rump. Two subspecies (Swayne's hartebeest and the tora) are listed as endangered
