HABITAT AND ECOLOGY
Red-shanked douc langurs occur in subtropical and tropical broadleaf evergreen or semi-deciduous forests and to a lesser extent in secondary evergreen and mixed bamboo forests. Diurnal and arboreal, they travel through the canopy feeding predominantly on leaves, but also eat fruits, flowers, buds and bark. They mostly live in family groups of one single male and multi females, but regularly come together into larger groups of up to 50 animals in a fission-fusion association.
Hunting is the main threat - for subsistence use and traditional medicine - they are also hunted for the international pet trade.
