One of the most mysterious and striking primates of Central Africa’s forests. What sets it apart immediately is its owl-like face: a pale stripe runs straight down its nose and forehead, framed by dark fur, giving it the appearance of wearing a mask or a feathery owl’s face. This unusual facial pattern, along with its watchful eyes and secretive habits, makes it one of the most easily recognizable yet least-seen monkeys of the Congo Basin.

Unlike the brightly colored guenons that show off orange legs or flashy markings, the owl-faced monkey has a more subdued coat—mainly dark gray or olive, with a yellowish patch on its chest. This muted coloring, combined with its secretive behavior, helps it blend into the dense, misty mountain and bamboo forests it calls home. Its shy nature makes it a challenge to study, and for many years it was one of the least-known African monkeys. Even today, catching a glimpse of one in the wild feels like spotting a forest ghost.

The owl-faced monkey is also distinct in its diet and lifestyle. While most guenons are highly social, living in lively, noisy groups, Owl-faced monkeys are far more reserved. They live in small groups or even pairs, moving quietly through the undergrowth. Their diet includes fruits, seeds, leaves, and shoots, but they are particularly fond of bamboo, which is unusual among guenons and ties them closely to the high-altitude forests of Central Africa. Their more solitary, quiet habits make them stand out in a family known for its colorful and chatty members.
