Owl-faced monkey (Cercopithecus hamlyni). A guenon found in moist forests and bamboo forests of eastern Democratic Republic of the Congo and western Rwanda. Its long toes make it good at grasping objects, and it can store food in cheek pouches. Diurnal, it feeds on fruit, seeds, leaves, flowers, and insects, and forms matrilineal groups of one adult male with 5–11 females. It marks territory with scent left by a chest gland; after a pregnancy of about six months it usually gives birth to a single young, with an interbirth interval of about two years. Listed as Near Threatened due to habitat loss and hunting.
