Family: Colobinae
Colobus Guereza, or the Mantled Guereza, is a member of the Colobinae family, which contains Old World, leaf-eating monkeys. We chose the species for a couple reasons. First, its mantle of white long, white hair, which is distinct and the source of its name. Second, it is one of the only Colobinae species present in US zoos.
The Mantled Guereza is endemic to Equitorial Africa. It can be found in forests, woodlands, and wooded grasslands. Most prefer to live in the lower parts of the tree, but some can be found in high altitudes up to 3300 meters and are normally found near some type of water source. As a forest-dweller, the Mantled Guereza is arboreal and quadrupedal, …show more content…
When grooming, playing, and fighting there are 5 vocal sounds that have been recorded: roars, snorts, purrs, honks, and screams. In addition, the roar of a male at dawn or dusk is used as a way to space out groups. The 5 vocal sounds are also used as warning signals to alert others to the presence of their predators, crowned eagles and leopards. Specific responses have been documented to each predator—Mantled Guerezas will look up when they hear the eagle signal, and down for the leopard signal. Other signals are the flapping of the fringe fur, facial expressions, and body posture.
The Mantled Guereza was discovered by Edward Rüppell in the 1830s. Since then, the monkey has had a variety of interactions with humans. In addition to being hunted for its fur, the Mantled Guereza has been used in research and testing. However, the species has been resilient in the face of such negative effects; population numbers have stayed the same and increased in some areas of habitat destruction. As such, it is listed as Least Concern. It is part of the Colobus Species Survival Plan.
Colobus Guereza is present in many zoos across the US such as the Lincoln Park Zoo, LA Zoo, Woodland Park Zoo, St Louis Zoo, and Jacksonville
