Combined distribution of red-backed bearded saki and brown-backed bearded saki

The red-backed bearded saki[1][3] (Chiropotes chiropotes[4]) is a New-World monkey, from South America. It is a species of bearded saki.

Description and physical characteristics

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.[5] 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.

Lifestyle

Diet

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.[5]

They have dental adaptations which allow them to crack pods easily.

Behaviour

Chiropotes are diurnal primates, that is to say they are active from sunrise to just before sunset.[5] They live in groups of about forty members with both sexes, occasionally separated in clusters when travelling or looking for food, their main occupation.

Habitat

It is found North of the Amazon River and East of the Branco River, in Brazil, Venezuela and the Guianas.[5]

Reproduction

Females give birth to one cub at a time after five months gravidity, during the rainy season.

Conservation

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.[5]

Taxonomy

Skull.

Previously, this and all other dark-nosed

IUCN in 2008, which maintained all bearded sakis north of the Amazon River as C. chiropotes.[2] 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.[3][4]
