These troops consist of a dominant male and multiple females and their offspring. Members of the group spend most of their time in the center of the territory. Although it can move quickly, the colobus will hide from its attacker instead of fleeing. They sometimes belch in each other's faces as a friendly social gesture. The monkeys communicate with a songlike call, a warning call, and a mating call.
Locals say they are excellent weather forecasters because they are quiet when bad weather is coming.
Arab Legend has it that a colobus monkey will rip its skin when injured.
