White-nosed saki

White-nosed saki (Chiropotes albinasus) is a bearded saki in the genus Chiropotes, family Pitheciidae, the New World monkeys that also include the other titis, the sakis and the uakaris. The Mammal Diversity Database credits the species name to (I. Geoffroy Saint-Hilaire & Deville, 1848) and lists its country distribution as Brazil. It is endemic to the south-central Amazon rainforest in Brazil. The scientific and common names arose because early authors worked from dead specimens, in which the skin on and around the nose fades to a whitish colour, while in living animals the nose is bright pink. Males are black and females brown to brownish-grey, and it is the only bearded saki with a brightly coloured nose. It is medium-sized and eats seeds, fruit, flowers, bark, insects and leaves, lives in large social groups and breeds seasonally. The English Wikipedia article says the 2020 IUCN Red List report listed it as vulnerable with a decreasing population. The Mammal Diversity Database gives its IUCN Red List status as Vulnerable.
