Hamlyn’s Monkey Distribution
Hamlyn’s Monkey Characteristics
The Hamlyn’s monkey (Cercopithecus hamlyni), also called the owl-faced monkey, is an Old World monkey inhabiting the Congo’s bamboo and primary rain forests.
- The fur of an adult Cercopithecus hamlyni is black and olive-gray. The fur is darker on the lower abdomen, hind legs, and arms.
- An olive-gray tint appears on the backs of adults. Their almost monotonous fur makes them almost invisible to predators.
- The fur of these animals is long, thick, and delicate. However, the face of an adult Hamlyn’s monkey is its most distinctive feature.
- These primates have a horizontal stripe across the forehead and a vertical stripe from the center of the forehead to the lip area.
- These two bands vary in color from creamy yellow to white, forming a T-shaped facial marking.

Hamlyn’s Monkey Facts

- They live in groups of fewer than 10 individuals. Within these small groups, there is only a dominant male species.
- Hamlyn’s monkeys mark their territory with their scent to maintain their home range.
- Vocal communication is an orientation guide and source of belonging in this dense habitat.
