Capped langur range

The capped langur (Trachypithecus pileatus) is a species of primate in the family Cercopithecidae. It is native to Bangladesh, Bhutan, India, and Myanmar. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.[2] They are arboreal and gregarious by nature. A herd of capped langurs consists of 2 to 14 langurs led by a single male. They are herbivorous, eating leaves, twigs, buds and fruits.

Taxonomy

There are four recognized subspecies:[1]

  • Trachypithecus pileatus pileatus
  • Trachypithecus pileatus durga
  • Trachypithecus pileatus brahma
  • Trachypithecus pileatus tenebricus

Behaviour and ecology

Capped Langur in Kaziranga National Park

A study of their diet in winter found that they spend nearly 40% of the day time feeding on leaves, flowers and fruits. Leaves contributed nearly 60% of the diet and they foraged on as many as 43 different plant species.[3]
