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.
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.
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.
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.
It is found North of the Amazon River and East of the Branco River, in Brazil, Venezuela and the Guianas. [5]
Females give birth to one cub at a time after five months gravidity, during the rainy season. [7]
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]
Previously, this and all other dark-nosed bearded sakis were included as subspecies (or taxonomically insignificant variations) of C. satanas . Based on molecular and morphological evidence, C. utahickae , C. chiropotes and C. sagulatus were split from C. satanas in 2002. [4] C. chiropotes and C. sagulatus were the only members of the genus found north of the Amazon River, with the former west of the Branco River (a major zoogeographic barrier) and the latter east. [4] Supporting evidence for the basic split into four species of dark-nosed bearded sakis was published in 2003, though with one significant difference compared to the earlier study: They treated the population east of the Branco River as C. chiropotes (C. sagulatus in the 2002 study) and west of the river as C. israelita (C. chiropotes in the 2002 study). [3] The taxonomy proposed in 2003 was followed in Mammal Species of the World in 2005. [8] 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, [9] while C. chiropotes is not present in that country, [1] thereby matching what would be expected from a species pair separated by the Branco River. This is potentially problematic, as the type specimen of C. chiropotes is from Venezuela, [1] [10] which could leave israelita as a junior synonym of C. chiropotes, thereby matching the taxonomy proposed in 2002. [4] 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. [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.

The Pitheciidae are one of the five families of New World monkeys now recognised. Formerly, they were included in the family Atelidae. The family includes the titis, saki monkeys and uakaris. Most species are native to the Amazon region of Brazil, with some being found from Colombia in the north to Bolivia in the south.
The bearded sakis, or cuxiús, are five or six species of New World monkeys, classified in the genus Chiropotes. They live in the eastern and central Amazon in South America, ranging through southern Venezuela, Guyana, Suriname, French Guiana and northern and central Brazil. The species are entirely allopatric, their distributions being separated by major rivers.
Pitheciinae is a subfamily of the New World monkey family Pitheciidae. It contains three genera and 14 species. Pitheciines are forest dwellers from northern and central South America, east of the Andes.
The white-faced saki, called the Guianan saki and the golden-faced saki, is a species of the New World saki monkey. They can be found in Brazil, French Guiana, Guyana, Suriname and Venezuela. This species lives in the understory and lower canopy of the forest, feeding mostly on fruits, nuts, seeds, and insects. Although they are arboreal creatures and are specialists of swinging from tree to tree (brachiation), they are also terrestrial when foraging. White-faced sakis typically live around 14 years in their natural habitat and have been recorded to live up to 36 years in captivity. Sakis are active in the day and sleep highly elevated (15-20m) in trees with many leaves to shelter them from weather and flying predators.
The red-faced spider monkey, also known as the Guiana spider monkey or red-faced black spider monkey, is a species of spider monkey found in the rain forests in northern South America.
The Emilia's marmoset, also known as Snethlage's marmoset, is a marmoset endemic to Brazil. It is found only in the Brazilian states of Pará and Mato Grosso. It was named to honour German-born Brazilian ornithologist Emilie Snethlage.
Martins's tamarin or Martin's ochraceous bare-face tamarin, is a species of tamarin endemic to Brazil.
The Lucifer titi monkey is a species of titi, a type of New World monkey, from South America. It is found in Brazil, Colombia, Ecuador, and Peru. It was described as Callicebus lucifer in 1914. The Lucifer titi has previously been treated as part of C. torquatus, the collared titi.
The collared titi monkey is a species of titi, a type of New World monkey. It is endemic to northern Brazil.
Stephen Nash's titi monkey, also known as just Nash's titi or Stephen Nash's monkey, is a species of titi monkey, a type of New World monkey, endemic to the eastern bank of the Purus River in Brazil. It was discovered by Marc van Roosmalen in 2001 when local fishermen brought specimens to his breeding center. It was described in 2002. It was named in honor of Stephen D. Nash, an illustrator for Conservation International, the organization that funded van Roosmalen's work. The monkey is largely silver with a black forehead and red sideburns and chest, as well as on the underside of the species' limbs. It is 28 inches long, although 17 inches is taken up by the titi's tail.
Hershkovitz's titi monkey is a species of titi monkey, a type of New World monkey, from South America. It is found in Bolivia, Brazil, and Peru. The common name is in reference to American zoologist Philip Hershkovitz, who described the species as Callicebus dubius in 1988.
The white-nosed saki is a species of bearded saki, a type of New World monkey, endemic to the south-central Amazon rainforest in Brazil. Both its scientific and common name were caused by the authors working from dead specimens, where the skin on and around the nose fades to a whitish color. In living individuals, the nose is actually bright pink. Pelage on the body tends to be black in males and brown to brownish-grey in females. No other species of the genus Chiropotes have a brightly coloured nose.
Uta Hick's bearded saki is an endangered species of bearded saki, a type of New World monkey. It is endemic to Brazil, where restricted to the Amazon between the Xingu and Tocantins Rivers. It was formerly treated as a subspecies of the more easterly C. satanas, but its back is pale brownish.
The black bearded saki is a species of New World monkey, native to the Amazon rainforest of South America, specifically to an area of north-eastern Brazil. It is one of five species of bearded saki. Bearded sakis are medium-sized (50 cm), mostly frugivorous primates, specialised in seed predation. The genus name Chiropotes means "hand-drinker" as they have been observed using their hands as ladles for scooping water into their mouths. This behavior is thought to be a way of maintaining and protecting their characteristic beards. The black bearded saki's habitat has undergone heavy habitat fragmentation, making the future conservation status of the species uncertain.
The brown-backed bearded saki is one of five species of bearded saki, a type of New World monkey. It is endemic to the Amazon in north-western Brazil and southern Venezuela. It is possible the correct scientific name for this species is C. chiropotes, in which case the more easterly red-backed bearded saki would be named C. sagulatus. The IUCN lists the reddish-brown bearded saki as a valid species, with C. israelita as a synonym, but also notes they might both be valid.
The Guyanan red howler is a species of howler monkey, a type of New World monkey, native to Suriname, Guyana, Trinidad, French Guiana, Venezuela and Brazil.
The Aracá uakari, also known as the Ayres black uakari, is a newly described species of monkey from the northwest Brazilian Amazon. It was found by Jean-Phillipe Boubli of the University of Auckland after following native Yanomamo Indians on their hunts along the Rio Aracá, a northern tributary of the Rio Negro. It was subsequently described in 2008 together with the more westerly distributed Neblina uakari. Until then, the black-headed uakari was the only species of mainly black uakari that was recognized. Stephen F. Ferrari et al proposed treating the Aracá uakari as a subspecies of the black-headed uakari rather than as a separate species.
The red-capped tamarin, is subspecies of moustached tamarin from South America. They are found in Brazil, on the eastern margin of the Tefé and Coari rivers. Previously recognised as a separate species, Saguinus pilatus, the red-capped tamarin was demoted to subspecies status by a taxonomic review by Rylands et al., (2016).
The Neblina uakari or black-headed uakari, is a newly described species of monkey from the far northwest Brazilian Amazon and adjacent southern Venezuela. It was found by Jean-Phillipe Boubli of the University of Auckland and described together with the more easterly distributed Aracá uakari in 2008. Until then, the black-headed uakari was the only species of mainly black uakari that was recognized.
