Description

These small (around 1kg), nocturnal monkeys live in northern Columbia and Venezuela. They have large umber eyes, a light grey coat with a buff underside. Their faces are distinctive with a white colouration and black marking around the edge. Sensitive to light, they have even been shown to be disturbed by the light of a full moon.

 
 

Behaviour

Although nocturnal, Grey-handed Night Monkeys are also very active around dawn and dusk, often seen foraging in small family groups made up of a breeding pair and their offspring, looking for fruits, leaves, nectar and insects.

Threats and Conservation

Less than 20% of the original habitat for this species still exists, destroyed for cattle farming, mining and agricultural products. The Grey-handed Night Monkey is also under pressure from capture, partly for subsistence hunting but also for the pet trade.
