Mantled Guereza - Ecology

Ecology

This species is primarily arboreal, but does sometimes descend on the ground for foraging and traveling, perhaps more so than most other colobines. The guereza is diurnal, being active during the daytime. It rests for much of the day. The foraging is usually the second most common activity, although sometimes moving around is next. During the day, guerezas have long rest periods in between periods of moving and feeding. Sometime after dawn, guerezas leave their sleeping trees and later return to them at dusk. Other activities, including grooming, greeting, playing and being vigilant, are performed at a lesser extant.
