#pitheciidae

Mittermeier's Tapajós Saki (Pithecia mittermeieri), family Pitheciidae, endemic to West-central Brazil

In 2014 this species population was elevated to species status, being split off from Rio Tapajós Saki (P. irrorata).

Research in 2019 suggests that it may not actually be a different species... its status is still disputed.

Coppery Titi Monkey Plecturocebus cupreus

They are found in the Amazon of Brazil and Peru, and perhaps northern Bolivia. 75% of their feeding time consists of eating fruit, and the other 25% is spent eating bamboo, leaves, and some insects. They live in family groups which consist of an adult pair and up to three generations of off-spring. The adult pairs are monogamous and mate for life. Family members may engage in tail-intertwining before and during sleep.

WHITE FACED SAKI Pithecia pithecia ©Laura Quick The white-faced saki, called the Guianan saki and the golden-faced saki, is a species of the New World monkey. They can be found in Brazil, French Guiana, Guyana, Suriname and Venezuela. They eat a mixed diet of seeds, fruits, leaves, honey, flowers, insects, and small mammals and birds and typically ingest seeds and plants that are high in lipid composition. 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. Other New World Monkeys:

Black-fronted Titi Monkey Callicebus nigrifrons

It is endemic to the Atlantic forest region of Brazil. It is arboreal and prefers the middle to upper canopy of the forest. However, it will move to the forest floor at times to forage, travel, and play. Play behavior on the forest floor has been documented between black-fronted titis and marmosets in Brazil.
