Behaviour
They live in groups of 11-64, typically 1 male:multi-female, but occasionally multimale:multifemale. They have a home range of 200-1200ha. Hanuman langurs spend up to 80 per cent of their time on the ground, although they will also spend time in the trees. They are diurnal and move quadrupedally. When a new male takes over a troop, he systematically kills all the infants sired by the previous alpha male.

Reproduction
After a gestation period of 168-200 days, females give birth to one infant. The infant is weaned after 13-20 months.

Conservation status
The IUCN classify the Hanuman langur as Lower Risk.
