Cercopithecus hamlyni. Owl-faced monkey.
Belgium. Antwerp Zoo.
This species ranges from the the eastern Democratic Republic of the Congo, where it is found in lowlands from the Congo/Lualaba River to the Ituri Forest and into the Albertine Rift and Nyungwe Forest in Rwanda. It occurs north to the Lindi-Nepoko river system and south to the southern tropical moist forest limit, where its range limit is poorly defined. Although it is generally a lowland species, it also occurs in the mountains of Albertine Rift, where many records come from the bamboo zone. The easternmost highland populations of C. hamlyni are now isolated in fragmented habitat islands and some have been extirpated (e.g., Gishwati, Rwanda, the Virunga Volcanos, and forest islands between Kahuzi-Biega National Park and Massisi). The species occurs above 3,000 m in both Tshiberimu and Kahuzi, so it seems safe to assume that 3,200 m is the upper elevation limit.
