They write new content and verify and edit content received from contributors. Sometimes, males will even harass the females and engage in infanticide, killing their infants, in order to force mating receptivity upon the female, who is not receptive to mating as long as she is nursing an infant.

[10] However, more recent observations have shown variation in structure and the number of males within groups, with one species forming multi-male, multifemale groups in a multilevel society, and in some populations supergroups form exceeding 500 individuals. A possible subspecies known as C. p. dollmani can be found but is most likely a hybrid with C. These adaptations allow the monkeys to grip branches as they climb, although reduce their ability to pluck food items. Groups of olive colobuses are often seen with Diana monkeys.
