The white-fronted capuchin, ''Cebus albifrons'', is a species of capuchin monkey, a type of New World primate, found in seven different countries in South America: Bolivia, Brazil, Colombia, Venezuela, Ecuador, Peru, and Trinidad and Tobago. The species is divided into several different subspecies, though the specific divisions are uncertain and controversial. This primate is a medium-sized monkey with a light brown back and a creamy white underside. Like other capuchin monkeys, it is omnivorous, feeding primarily on fruits, invertebrates, other plant parts and sometimes small vertebrates. It is predated upon primarily by raptors and probably small cats, especially the margay, though snakes have been known to attack the species. It is a polygamous animal and lives on fairly large groups of 15 to 35 individuals, reproductive females give birth to a single young at biennial intervals. The species maintains a home range of and has a complex vocal repertoire. It is one of the few primates to have been observed crafting and utilising tools in the wild. White-fronted capuchin populations are declining. The decline is believed to be caused by human-induced habitat loss and degradation, and hunting. In 2008 the International Union for Conservation of Nature (IUCN) classified the Ecuadorian white-fronted capuchin (ssp. ''aequatorialis'') and the Trinidad white-fronted capuchin (ssp. ''trinitatis'') as ''critically endangered'', and the varied white-fronted capuchin (ssp. ''versicolor'') in Colombia is classified as ''endangered''. The total population of the Trinidad subspecies was 61 at the last census. == Taxonomy == This species has had problems with its name, description and type locality. The holotype does not exist; the original description by Alexander von Humboldt in 1812 describes an animal that is much darker (grayish) than those that exist close to the type locality, and the description includes a dark tail tip, a character that is completely unknown in any population of the species. Additionally, the animal which von Humboldt examined was a tame animal in Maipures, where the species is not usually found. The closest population is about three kilometers to the north, on the other side of the Tuparro River. Defler and Hernández established a neotype from the population that was called ''Cebus albifrons albifrons'' by Hernández C. and Cooper. Another problem has been that the taxon ''C. a. unicolor'' described by Spix (1823) and further defined by Hershkovitz was indistinguishable from ''C. a. albifrons''; the two are synonymous. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「White-fronted capuchin」の詳細全文を読む スポンサード リンク
