The mantled guereza^[1] (Colobus guereza), also known as the guereza, Abyssinian black-and-white colobus, or eastern black-and-white colobus, is a black-and-white colobus, a species of Old World monkey.

• The Colobus genus members differ from members of the other subfamily, Cercopithecinae, by not having cheek pouches and the presence of prominent ischial calluses, separate in females and contiguous in males.
• The coat color is clearly black and white. The face is gray and hairless.
• The face and calluses are outlined in white. On the sides is a white U-shaped coat of different lengths.
• The outer part of the thigh is variously whitish, and the tail is whitish or yellowish from tip to base. Also, there is a large white tuft at the end of the tail.

Spotted Hyenas (Crocuta crocuta) and Lions (Panthera leo) predate on Mantled Guerezas^[§].

• The mantled guerezas are typically diurnal. Therefore, they are very arboreal inhabitants of the deep forest. However, when the trees are not dense, the guerezas feed and move along the ground.
• They live in sexually mixed groups averaging 8-15 individuals, usually with a single adult male and 3 or 4 breeding females, juveniles, and infants.
• These colobus monkeys spend most of their time perched high in trees; they take turns sleeping at night, so there is always at least one person awake to watch predators.
• Unlike females, young male species leave their birth group before reaching maturity.
• There’s no real group leader, but strong males usually take on leadership roles.
