The white-faced saki (Pithecia pithecia), also known as the Guianan saki and the golden-faced saki, is a species of saki monkey, a type of New World monkey, 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, but also eating nuts, seeds, and insects.
There are two recognized subspecies of this monkey:
- Pithecia pithecia pithecia
- Pithecia pithecia chrysocephala
Reproduction
In captivity, female white-faced sakis experience ovarian cycles of approximately 17 days, and a gestational period of 20–21 weeks. Following birth, the mother undergoes a period of lactationally-induced infertility lasting 23 weeks, on average.[3]
Sakis of the Pithecia pithecia species display noticeable sexual dichromism in their coloration. Females have shorter hair than males, with brownish-grey fur and white or pale brown stripes around the corners of the nose and mouth. Males, on the other hand, have blacker fur, with a reddish-white forehead, face, and throat.[4]
Behavior
A pair often mates for life. They are very devoted and will strengthen their bond by grooming one another.
