The equatorial saki (Pithecia aequatorialis), also called the red-bearded saki, is a species of saki monkey, a type of New World monkey. It is found in northeastern Peru and Ecuador.[3]

Not much is known about the equatorial saki, its range being specifically unknown.[4]

Description

The equatorial saki weighs between 2 - 2.5 kg, has a head-body length of 39 – 44 cm, and a tail length of 45 – 47 cm. The species' tail in not prehensile, relying on its arm and leg strength to carry itself from branch to branch.[5] The equatorial saki is also sexually dimorphic. It is often confused for the monk saki, but the reddish throat and chest of the equatorial saki set it apart.[6]

Ecology

The equatorial saki is diurnal. The species is frugivorous, but seeds and nuts constitute a large part of diet. This species also consumes leaves and insects, especially ants. The fruits that this species consumes have hard pericarps.[7] Most of its time is spent foraging in the middle to upper levels of the rainforest canopy.[6]

They seem to be found most commonly in riverside, seasonally flooded and swamp forests, but have been seen in terra firme forests as well.[6]

The red-bearded saki moves through the forest both quadrupedally and by leaping. When the red-bearded saki takes off from a tree branch, most likely it does this from a vertical clinging position.[7]

The equatorial saki lives in small groups of two to four that come together to form larger congregations. Groups of red-bearded sakis are described as closed social units. Males groom their young.[7]
