Dik-dik are small, delicate antelope with large eyes and large ears and a tuft of long hair on the forehead. The males have small spike-horns often covered by their tuft. The snout is elongated and a prominent dark patch occurs just before the eyes, which are ringed in white. Dik-diks live in monogamous pairs with their recent offspring. They live in areas with considerable vegetative growth for cover, into which they seek refuge when threatened. Dik-dik do well in dry areas as long as sufficient stands of brush remain. They do not need to drink, obtaining the moisture they require from the plants they eat. They are shy and elusive, rarely leaving the brush. If startled, they flee in a series of erratic, zig-zag jumps while uttering a distinctive "zik-zik" alarm call. This alarm alerts other game to the presence of danger, as a result these little antelope are often disliked by hunters.
