Habitat and Ecology

This species is present in many different forest types including lowland and montane tropical moist forest, riverine and gallery forest, delta forest and bamboo forest. Also found in sand forest. It can occur in secondary forest, logged forest and thickets. Group size ranges from 2 to more than 40 individuals. The gestation period is around 176 days after which a single young is usually born.


Their main diet is shoots, fruits, leaves, flowers and berries, but they do also consume eggs, insects and any opportunistic human food they can get their hands on (especially when it comes to unsuspecting tourists).


Sykes are very territorial and live in female bonded; single-male troops and the group size can vary between 4-65. The groups are very stable and peaceful with the resident male maintaining dominance for years and the sub-adult males being evicted readily. Sometimes an outsider male will learn to imitate the call of the group’s dominant male to attract the females away.


The mating system is polygynous, and there is a corresponding sexual dimorphism in size, with the males substantially the larger sex. Females normally give birth every two years, during the onset of the warm, rainy season; gestation is around five months, and the infants are born with fur and with their eyes open. Group sizes range from 10 to 40, containing only a single adult male.
