A dik-dik is a small antelope that lives in the bushlands of eastern and southern Africa. Dik-diks stand approx. 12–16 inches (30–40 cm ) at the shoulder, are approx. 20–28 inches long (50–70 cm ), weigh approx. 7–16 pounds (3–6 kg ) and can live for up to 10 years. Dik-diks are named for the alarm calls of the females. In addition to the female's alarm call, both the male and female make a shrill whistling sound. These calls may alert other animals to predators.
