  • Weight: 1 – 2 kg
  • Best season: October – March
  • Sightings: 95%

The monk saki monkey is a medium-sized primate found in the tropical forests of the Amazon Basin. It is known for its dense, shaggy fur and a striking, monk-like facial appearance. This arboreal species is primarily frugivorous but also feeds on seeds, leaves, and small animals. Monk sakis are elusive and prefer the dense canopy, where they live in small family groups. They are listed as Least Concern, but habitat loss poses a potential threat.

In the Tamshiyacu – Tahuayo Communal Reserve we can oftenly spot this beautiful specie while we go for jungle hikes and boat rides as they jump on tree’s branches near the river sides searching for fresh fruits 

SIZE

Males are slightly larger than females, with more robust bodies and stronger limbs, aiding in territorial defense and climbing.

COLORATION

Males typically have darker, more uniform fur, giving them a distinctive monk-like appearance. Females may have lighter fur tones and subtle variations in facial markings.

BEHAVIOR

Males are often more dominant and territorial, while females focus more on nurturing and offspring care. This dimorphism plays a role in mating behaviors and social dynamics within their small family groups.

CONSERVATION EFFORTS

Many populations reside in protected regions, such as national parks and reserves. For instance, the Tamshiyacu – Tahuayo Communal reserve.

ECOLOGICAL IMPORTANCE

As frugivores, monk saki monkeys play a critical role in dispersing seeds throughout the Amazon rainforest. By consuming fruits and excreting seeds in different locations, they promote forest regeneration and biodiversity.
