The common duiker, Sylvicapra grimmia, also known as the grey 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 habitats with sufficient vegetation cover to allow them to hide—savanna and hilly areas, including the fringes of human settlements.
The Common Duiker has a lifespan of about 12 years. Colouration of this species varies widely over its vast geographic range. As many as 19 subspecies are thought to exist, 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 50 cm (20 in) in height and generally weighs 12 to 25 kg (26 to 55 lb); although females are generally larger and heavier than the males. The males' horns can grow to 11 cm (4.3 in) long.
The Common duiker is sexually mature after six months, some females get their first young after one year. Breeding is year round and the female gives birth to one fawn after a gestation period of what is variously estimated at 3.0 to 7.5 months. This fawn can walk one day after it is born but will hide in bushes for the first few weeks of his life. If the young is in danger the mother is able to scare predators away by hitting them with her horns. The common duiker has a wide diet; beyond herbivorous browsing for leaves, flowers, fruits and tubers, they will also eat insects, frogs, small birds and mammals, and even carrion. As long as they have vegetation to eat (from which they get some water), they can go without drinking for very long periods. In the rainy season, they will frequently not drink water at all, instead obtaining fluids from fruits. They will often scavenge for these fruits below trees in which monkeys are feeding. They are active both day and night, but become more nocturnal near human settlements.
Males are territorial and smear gland secretions on rocks and branches to mark their territories; their preferred resting places are generally on elevated ground, where they can observe their territory. Females, by contrast, prefer deeper cover. The overall success of this species stems from its ability to inhabit a wide variety of habitats, as well as from its adaptable, generalist diet.
