Красный саки с бородой: описание и таксономия.

Species of New World monkey

The red backed bearded saki (Chiropotes chiropotes) is a New World monkey, from South America. It is a species of bearded saki.

The Red backed bearded saki has a thick beard, especially males. It has a shock of hair on each side of its head. Its body is entirely covered with dense hair whose colour varies from red to yellowish gold. Its non prehensile, bushy tail is almost as long as its body. Females are generally smaller than males. The latter is about 45 cm long and between 2.6 and 7.1 kg. It moves on its four legs but is able to stand upright.

Red backed bearded sakis are primarily frugivores, feeding on seeds, flowers, nuts and fruits but their diet also includes insects, larvae and spiders. They can eat about 100 different species of plants.]]

Chiropotes are diurnal primates, that is to say they are active from sunrise to just before sunset.

Red backed bearded sakis are not considered endangered by the International Union for Conservation of Nature (IUCN), even if they are sometimes hunted for their meat. There are 27 red backed bearded sakis in zoos around the world. In the study in 2003, a direct comparison of C. israelita and the type specimen of C. chiropotes was not included, but it is assumed that bearded sakis in Venezuela are C. israelita, while C. chiropotes is not present in that country, which could leave israelita as a junior synonym of C. chiropotes, thereby matching the taxonomy proposed in 2002. Due to this confusion, neither C. sagulatus nor C. israelita were recognized by the IUCN in 2008, which maintained all bearded sakis north of the Amazon River as C. chiropotes. However, regardless of the uncertainties over exactly what population the species name chiropotes belongs to, it is clear that there are two distinct populations of bearded sakis north of the Amazon River: A reddish backed from the Branco River and eastward, and a brown backed from the Branco River and westward.
