The common duiker (Sylvicapra grimmia), also known as the grey or bush duiker, is a small antelope and the only member of the genus Sylvicapra. This species is found 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. [2]

Description

Colouration of this species varies widely over its vast geographic range. There are 14 subspecies described, [1] 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. Only the male has horns and these can grow to 11 cm (4.3 in) long.

Behavior

Breeding is year round and the female gives birth to one fawn after a gestation period of 6 to 7.5 months. The common duiker has a wide diet; beyond 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, presumably due to the presence of feral dogs and humans.

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.

    The bay duiker, also known as the black-striped duiker and the black-backed duiker, is a forest-dwelling duiker native to western and southern Africa. It was first described by British zoologist John Edward Gray in 1846. Two subspecies are identified. The bay duiker is reddish-brown and has a moderate size. Both sexes reach 44–49 cm (17–19 in) at the shoulder. The sexes do not vary considerably in their weights, either; the typical weight range for this duiker is 18–23 kg (40–51 lb). Both sexes have a pair of spiky horns, measuring 5–8 cm (2.0–3.1 in). A notable feature of this duiker is the well-pronounced solid stripe of black extending from the back of the head to the tail.

    The blue duiker is a small antelope found in central, southern and eastern Africa. It is the smallest duiker. The species was first described by Swedish naturalist Carl Peter Thunberg in 1789. 12 subspecies are identified. The blue duiker reaches 32–41 centimetres (13–16 in) at the shoulder and weighs 3.5–9 kilograms (7.7–19.8 lb). Sexually dimorphic, the females are slightly larger than the males. The dark tail measures slightly above 10 centimetres (3.9 in). It has short, spiky horns, around 5 centimetres (2.0 in) long and hidden in hair tufts. The subspecies show a great degree of variation in their colouration. The blue duiker bears a significant resemblance to Maxwell's duiker.

Male dibatag weigh between 20 and 35 kg, whereas females range from 22 and 29 kg. The length of the curved horns, present only on males, is typically between 10 and 25 cm. The upper parts are gray to fawn, while the dorsal and lateral areas are cinnamon to rufous. The underparts, rump and the insides of the legs are all white. While markings are visible on the face, there are none on the flanks or the buttocks.

While the red forest duiker is very similar to the common duiker, it is smaller in size and has a distinguishing reddish coloring. Additionally, the red forest duiker favors a denser bush habitat than the common duiker. The Natal red duiker is more diurnal and less secretive than most forest duikers, so therefore it is easier for them to be observed. In 1999, red forest duikers had an estimated wild population of 42,000 individuals.

In addition, many other forest reserves are noted in the country but are not easily accessible, well protected or adequately surveyed for its wildlife resources. The protected area system of Benin defined as National Protected Area System is situated in the northern Benin, mostly with a woody savanna ecosystem. It covers 10.3% of the national territory and is part of the three nation transboundary W-Arly-Pendjari (WAP) complex.

The climate is tropical with distinct wet and dry seasons. There are estimated to be over 3000 species of vascular plant in the country, and 196 species of mammal and 676 species of bird have been recorded there.
