Impala

a noisy antelope renowned for its agile leaps. It has reddish-brown upper-parts becoming paler on the sides. The underparts, belly, throat and chin are white, as is the tail, which has a thin, black line down its center. A black line also extends down each buttock. At the back of the hind leg, just above the hoof, is a characteristic tuft of black hair, which covers the fetlock gland. A high kick sends out a puff of scent from the gland, which is thought to be used to lay trails and help regroup herds. Males have lyre-shaped horns.
