Duikers
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. Taxonomy and phylogeny The tribe Cephalophini (formerly the subfamily Cephalophinae) comprises three genera and 22 species, three of which are sometimes considered to be subspecies of the other species. The three genera include '' Cephalophus'' (15 species and three disputed taxa), '' Philantomba'' (three species), and '' Sylvicapra'' (one species). The subfamily was first described by British zoologist John Edward Gray in 1871 in '' Proceedings of the Zoological Society of London''. The scientific name "Cephalophinae" probably comes from the combination of the New Latin word ''cephal'', meaning head, and the Greek word ''lophos'', meaning crest. The three disputed species in ''Cephalophus'' are Brooke's du ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-backed Duiker
The yellow-backed duiker (''Cephalophus silvicultor'') is a shy, forest-dwelling antelope of 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 and Gambia on the western coast, through to the Democratic Republic of the Congo to western Uganda; their distribution continues southward into Rwanda, Burundi, and most of Zambia. Taxonomy and etymology The scientific name of the yellow-backed duiker is ''Cephalophus silvicultor''. It is the type species of '' Cephalophus'', and placed in the subfamily Cephalophinae and family Bovidae. The species was first described by English botanist Adam Afzelius in the journal ''Nova Acta Regiæ Societatis Scientiarum Upsaliensis'' in 1815. The generic name has possibly originated from the combination of the New Latin word ''cephal'', meaning head, and the Greek word ''lophos'', meaning crest. The specifi ...

White-bellied Duiker
The white-bellied duiker (''Cephalophus leucogaster'') 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. Duikers are fairly small species of antelope that originate from, and still reside in, sub-Saharan Africa. The white-bellied duiker ranges in Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Equatorial Guinea, and Gabon, while it is likely to have been extirpated in Uganda.(East, 1996) References {{DEFAULTSORT:duiker, white-bellied white-bellied duiker Fauna of Central Africa white-bellied duiker Taxa named by John Edward Gray ...

Zebra Duiker
The zebra duiker (''Cephalophus zebra'') 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. Taxonomy and etymology The scientific name of the zebra duiker is ''Cephalophus zebra''. The bay duiker is classified under the genus '' Cephalophus'' and the family Bovidae. It was first described by British zoologist John Edward Gray in 1838 in '' Annals of Natural History''. No subspecies are identified. The generic name probably comes from the combination of the New Latin word ''cephal'', meaning head, and the Greek word ''lophos'', meaning crest. The specific name ''zebra'' pertains to the striking resemblance this duiker bears to the zebra due to the presence of dorsal stripes. The word "duiker" comes from the Afrikaans word ''duik'', or Dutch ''duiker'' - both mean "di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peters' Duiker
Peters' duiker (''Cephalophus callipygus'') is a small antelope found in Gabon, Equatorial Guinea, southern Cameroon, and northern Republic of the Congo. Peters' duikers typically weigh about 40 lb (18 kg), and are about 20 in (50 cm) at the shoulder. They have grey-brown coats, and live in dense undergrowth in mountain rainforest Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropi ...s. The total population is estimated at 380,000 individuals, with a declining trend.

Maxwell's Duiker
The Maxwell's duiker (''Philantomba maxwellii'') is a small antelope found in western Africa. Taxonomy The scientific name of Maxwell's duiker is ''Philantomba maxwelli''. It is classified in the genus '' Philantomba'' along with the blue duiker (''P. monticola'') and Walter's duiker (''P. walteri''). It was first described by English naturalist Charles Hamilton Smith in 1827. The species is sometimes treated as a species of '' Cephalophus'', another genus of duikers, although ''Philantomba'' has been recognised as a genus by zoologists such as Peter Grubb and Colin Groves. Theodor Haltenorth has considered this species to be a race of the blue duiker due to their identical features. In 2012, Anne R. Johnston (of the University of Orleans) and colleagues constructed a cladogram of the subfamily Cephalophinae (duiker), that includes the three genera '' Cephalophus'', ''Philantomba'' and '' Sylvicapra'', based on mitochondrial analysis. ''Philantomba'' was shown to be mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ogilby's Duiker
Ogilby's duiker (''Cephalophus ogilbyi'') is a small antelope found in Sierra Leone, Liberia, Ghana, southeastern Nigeria, Bioko Island and possibly Gabon. No subspecies are recognized. It is named after Irish zoologist William Ogilby. The two former subspecies, the white-legged duiker ''Cephalophus crusalbum'' and the Brooke's duiker ''Cephalophus brookei'', are considered as distinct species since 2011.Colin Peter Groves & Peter Grubb: Ungulate Taxonomy, Johns Hopkins University Press, 2011. Ogilby's duikers weigh up to and have a shoulder height of up to . They vary in color from chestnut to mahogany to deep brown, and have massive hindquarters typical of duikers. Ogilby's duikers live mainly in high-altitude rainforests, where they feed mainly on fallen fruit In botany, a fruit is the seed-bearing structure in flowering plants (angiosperms) that is formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate their seeds. Edible fru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Duiker
The black duiker (''Cephalophus niger''), 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. Black duikers stand around tall at the shoulder and weigh . They have, not surprisingly, black coats. The head is a rust colour with a large red crest between the ears. Black duikers have long, thin horns of , but the horns of females reach only . Black duikers live mainly in lowland rainforest, where they eat fruit, flowers, and leaves which have fallen from the canopy. They are probably diurnal, though this is surmised only from captive specimens. Black duiker are reported to be solitary, territorial animals. The mating season of the black duikers is year round, but more offspring are born from November to January. The gestation period lasts 126 days, and is thus comparably short, usually only one young is born. Its average weight is 1.94 kg; it is weaned around 90 days o ...

Harvey's Duiker
The Harvey's red duiker (''Cephalophus harveyi'') is one of 19 species of duiker found in Tanzania and scattered through Kenya, southern Somalia and possibly central Ethiopia. Harvey's duikers are roughly 40 cm (15 in) tall at the shoulder and weigh around 15 kg (33 lb), on average. They have mostly chestnut coats, but their legs and faces are black. Harvey's duikers live in mountain and lowland forest, where they eat leaves, twigs, fruit, insects, birds eggs, and carrion Carrion (), also known as a carcass, is the decaying flesh of dead animals. Overview Carrion is an important food source for large carnivores and omnivores in most ecosystems. Examples of carrion-eaters (or scavengers) include crows, vultures .... Although this duiker is not endangered, it is dependent on protected forestland. As of 2008, this species is of least concern.
