Highly attractive to other females, infants may be carried by any in the group (infant transfer). They initially make little frog-like jumps, becoming more and more independent. They will cling most of the time for the first month. Newborns are snow-white, with black skin. For the first few days, it is held in place with one hand during a jump. A 6-month gestation brings a single baby that hangs on under mom’s belly. There tends to be a birth peak, timed so that weaning coincides with the greatest seasonal abundance of solid food.īreeding pairs move away from the group (and the female, accompanied by the male, moves away when she delivers). There is no real hierarchy, no genital swelling and no distinct breeding season. There is mutual grooming and seldom any squabbles. Breeding & GrowthĬolobus are usually found in sexually mixed groups averaging 8-15 individuals, with only one fully adult male and 3 or 4 reproductive females. Of the remainder of the time, 20% is devoted to eating, and 5% is spent traveling.

Cows and other ruminants, plus such mammals as gorillas and the Colobus spend a large amount of time resting for digestion. Microbial assistance is necessary in any animal (even termites) that must deal with cellulose. It requires an especially large portion of the day for quiet rest. Because of the high cellulose content, a leaf diet is difficult to digest. It is separated from the lower acid region. The expanded upper region is a storage chamber that is quickly packed with leaves during a feeding foray. The essential feature is that it is sacculated, chambered like a ruminant or kangaroo. Besides man and the occasional leopard, their primary predators are large eagles.Ĭolobus have an unusual stomach. When fleeing, Colobus do some fantastic leaping.

A full thumb would interfere with brachiation.
The rudimentary thumb, often only a “tubercle” in the thumb’s place, is thought to be part of the development toward brachiation. They often freeze rather than flee when scared.Ĭolobus do a crude form of brachiation, swinging and maneuvering with all four feet when moving through their territory. The bold color pattern serves to break up their outline and these striking monkeys are very difficult to see in the canopy amongst the leaves. It does billow out and would create drag, but no actual study has been done. Some observers feel that the beautiful long white hair (much sought-after for high-fashion coats) serves as a kind of parachute, slowing their landing speed. They are outstanding jumpers, able to leap great distances, tree to tree. AdaptationsĬolobus are almost completely arboreal. Baboons are dominant, then a large hornbill, then Guerezas and finally White-Throated (Red-bellied) Guenon (Cercopithecus erythrogaster). Seldom flighty, they show some hierarchy with a few other species. Colobus circulate through well-defined feeding territories of about 40 acres. They apparently prefer young leaves, changing locations when all the tender leaves are gone. Feeding Colobus move slowly and deliberately, quietly pulling leaves and buds off. Distressed young squeak, with quick response from mom. This vocalization is territorial (called acoustical marking) and is taken up by the entire troop during its daily rounds. BehaviorĪn animal separated from its group emits a guttural “orr-orr-orr” call. Babies are completely white, showing a black undercoat in 2-3 months. Glossy black fur sports a white ring around the face and a white fringe and tail-brush.
