Miller’s saki^[1] (Pithecia milleri), also called Miller’s monk saki, is a species of saki family, a type of New World Monkey.

• Its range includes parts of northeastern Ecuador, southwestern Colombia, and possibly adjacent areas in Peru.
• The Miller’s saki belongs to the Pithecia monkey family. Species in this group are characterized as medium-sized monkeys with long, coarse hairs that swell up (known as piloerection) when approached in the wild, making them appear larger than they really are.
• The hair on their head is directed forward like a hood.
• Like other sakis, the males and females of this species have different colored fur, with the females being grayer on the face and overall and the males a darker grayish-black but with brown on the face and the forearms.

• Miller’s sakis are diurnal and quadrupedal leapers. They usually move on all fours but can be seen swinging bipedally on large branches before leaping to another tree.
• During the day, these sakis move in pairs or small family groups around their home range.
• These species vocalize in growls, squeaks, hisses, and low calls.
• Due to their diet, Miller’s sakis disperse the seeds of the fruits they eat, which benefits the local ecosystem.
• Populations of this monkey are threatened by hunting and habitat loss.
