Monk Saki Monkey

Pithecia Monachus


Saki monkeys are small sized primates, with adults weighing in around 2kg (4lbs) - about the size of a large rabbit. They have long nonprehensile tails, so they rely on just their hands and feet to move from branch to branch in rainforest canopy trees. Monk Saki monkeys are often confused with their close cousin, the equatorial saki. Equatorial sakis have an orange throat, chest and belly, which the Monk Saki lacks.


Monk sakis are diurnal (active during the day) and spend their time foraging in the middle to upper levels of the rainforest canopy. They travel in small family groups in search of fruits, seeds, leaves, and ants. They prefer terra firme forest but have been spotted in seasonally flooded forests as well. Monk sakis tend to be shy and quiet and avoid disturbed areas, making them a challenge to see in the wild.


These photos were taken an Isla de los Monos, an island refuge for Amazon primates who have been injured and orphaned in the wild or for monkeys that have been rescued from human captors. The monkeys have free range on the island and will eventually leave the island and return to the wild.

Yay! Just learned how to tell the difference between a Monk Saki and their cousin the Equatorial Saki. Check the notes for how to tell them apart.

Thanks everyone - especially the Rangers who help us identify so many of our spottings! We are gearing up for another Amazon expedition in July and hope we can enlist Ranger help in correctly identifying our current spottings before we add the next big round!
