Hamlyn's Monkey—Also Called Owl-Faced Monkeys or Owl-Faced Guenons
This is the Hamlyn's monkey (Cercopithecus hamlyni)! Because the Hamlyn’s monkey is a particularly shy species and difficult to observe in the wild, not much is known about their lifestyle. We do know that they are diurnal, meaning they are active during the day and sleep through the night. They also spend most of their time on the ground, making them primarily terrestrial, and will only sometimes climb among the trees to forage or evade potential predators. Unique among other more terrestrial primates, Hamlyn’s monkeys have particularly long fingers. This adaptation makes it easier to climb in trees, hence why it is unusual for a primarily terrestrial primate. Because Hamlyn’s monkeys are often found in bamboo forests, their exceptionally long digits help them climb among the smooth bamboo stalks. Based on their location, Hamlyn’s monkeys are likely preyed on by leopards and crowned eagles. Learn more: https://neprimateconservancy.org/
