A duiker is a small to medium-sized brown antelope native to sub-Saharan Africa, found in heavily wooded areas. The 22 extant species, including three sometimes considered to be subspecies of the other species, form the subfamily Cephalophinae or the tribe Cephalophini.
The Abbott's duiker, also known as minde in Swahili, is a large, forest-dwelling duiker found only in a few scattered enclaves in Tanzania. It may be a subspecies of the yellow-backed duiker. It is very rare, and the first photograph of an Abbott's duiker in the wild was taken as recently as 2003.
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 black duiker, also known as tuba in Dyula, is a forest-dwelling duiker found in the southern parts of Sierra Leone, Liberia, Côte d'Ivoire, Ghana, Benin, and Nigeria.
The blue duiker is a small antelope found in central, southern and eastern Africa. It is the smallest species of 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.
Jentink's duiker, also known as gidi-gidi in Krio and kaikulowulei in Mende, is a forest-dwelling duiker found in the southern parts of Liberia, southwestern Côte d'Ivoire, and scattered enclaves in Sierra Leone. It is named in honor of Fredericus Anna Jentink.
The white-bellied duiker is a duiker found in central Africa. Little is known on the ecology of the species, and only some information on habitat and diet is available.
The Harvey's red duiker is one of 19 species of duiker found in Tanzania and scattered through Kenya, southern Somalia and possibly central Ethiopia.
The black-fronted duiker is a small antelope found in central and west-central Africa.
The Maxwell's duiker is a small antelope found in western Africa.
Peters's duiker is a small antelope found in Gabon, Equatorial Guinea, southern Cameroon, and northern Republic of the Congo.
The red-flanked duiker is a species of small antelope found in western and central Africa in countries as far apart as Senegal and Sudan. Red-flanked duikers grow to almost 15 in (35 cm) in height and weigh up to 31 lb (14 kg). They have russet coats, with greyish-black legs and backs, and white underbellies. They feed on leaves, fallen fruits, seeds and flowers, and sometimes twigs and shoots. The adults are territorial, living in savannah and lightly wooded habitats, and the females usually produce a single offspring each year. They have lifespans of ten to fifteen years in captivity.
The Ruwenzori duiker or Ruwenzori red duiker is a stocky but small antelope found only in the Ruwenzori Mountains between Uganda and, probably, the Democratic Republic of Congo. They may be a subspecies of the black-fronted duiker or the red-flanked duiker.
Weyns's duiker is a tiny antelope found in the Democratic Republic of Congo, Uganda and western Kenya. It is sometimes spelled "Weyn's", "Weyns", or "Weyns'" duiker.
The zebra duiker is a small antelope found primarily in Liberia, as well as the Ivory Coast, Sierra Leone, and occasionally Guinea. They are sometimes referred to as the banded duiker or striped-back duiker. It is believed to be one of the earliest duiker species to have evolved.
The yellow-backed duiker is a forest dwelling antelope in the order Artiodactyla from the family Bovidae. Yellow-backed duikers are the most widely distributed of all duikers. They are found mainly in Central and Western Africa, ranging from Senegal to Western Uganda with possibly a few in Gambia. Their range also extends southward into Rwanda, Burundi, Zaire, and most of Zambia.
The red forest duiker, Natal duiker, or Natal red duiker is a small antelope found in central to southern Africa. It is one of 22 extant species form the subfamily Cephalophinae. 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.
Cephalophus is a mammal genus which contains at least fifteen species of duiker, a type of small antelope.
The white-legged duiker is a medium-sized antelope species from the subfamily of duikers (Cephalophinae) within the family of bovids (Bovidae). It is native to Gabon and the Republic of the Congo. It was described as subspecies of the Ogilby's duiker by Peter Grubb in 1978. After a revision of the ungulates in 2011 by Colin Groves, it is now regarded as distinct species.
