Toque Macaque (Macaca sinica) lives in tropical rainforest across Sri Lanka. It feeds on fruits and insects. Its conservation status is Endangered.
Fascinating facts about the Toque Macaque
- The monkey's crown bears a single whorl of hair that looks like a brimless toque cap, a traditional hat that gave rise to its English name. This distinctive pattern is highlighted in its scientific name, Macaca sinica, which despite meaning "of China" refers to a Sri Lankan species. The animal is a reddish-brown Old World monkey found only on the island, where locals call it riḷawā. Its name therefore directly describes the unique hair arrangement on its head.
- Troops can be as small as eight individuals, but at the other extreme a single group may swell to as many as forty members. When a troop grows too large, social tension and aggression increase, prompting some members to leave the group. Dominance hierarchies exist among both males and females, and newly appointed alpha males often drive females away, further influencing group size. These dynamics keep troop numbers within a functional range.
- During birth the mother stands on two legs and uses her hands to help the infant emerge, a characteristic bipedal stance in their parturition behaviour. After a 5-6 month gestation the female gives birth to a single offspring, which clings to its mother for about two months while learning vital social skills. The mother resumes foraging within twenty minutes of delivery, ensuring the troop's food supply continues uninterrupted.
- Newborns are able to vocalise within seconds of being born. Their cries let mother and baby recognise each other's voices instantly.
- The Sri Lankan government once planned to export 100,000 monkeys to China. The scheme was abandoned after conservationists and zoologists protested.
