Grey Duiker (Sylvicapra grimmia)

The Common Duiker, also known as the Gray or Bush Duiker, is a small antelope with small horns found in west, central, east, and southern Africa- essentially everywhere in Africa south of the Sahara, excluding the horn of Africa and the rainforests of the central and western parts of the continent. Generally they are found in habitat that has sufficient vegetation cover to allow them to hide.

Physical Characteristics
Colouration of this species varies widely over its vast geographic range. There are thought to be as many as 19 subspecies ranging from chestnut in forested areas of Angola to grizzled gray in northern savannas and light brown shades in arid regions. It grows to about 4 feet (1.2 m) in height and generally weighs 12 to 25 kg; although females are generally larger and heavier than their male counterparts. The male bears horns which can grow to 4.25 inches (11 cm) long.
