Hanuman langur, common langur, grey langur, entellus langur, true langur
These langurs are named after the Hindu monkey-god Hanuman, and are the sacred monkey of India.
Head and body length: Female: 40-68cm, Male: 51-78cm. Tail length: 69-101cm. Weight: Female 11.2kg, Male: 18.3kg.
The colour of their fur ranges from grey, dark brown to golden with varying amounts of black, depending on the subspecies. They also vary in size - subspecies from the southern part of their range are smaller than those from the north.
They are found across India, Pakistan, Bangladesh, Sri Lanka and Burma.
Hanuman langurs inhabit tropical, dry thorn scrub, pine and alpine forest, and urban areas.
Hanuman langurs feed on leaves, fruit, buds and flowers.
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.
After a gestation period of 168-200 days, females give birth to one infant. The infant is weaned after 13-20 months.
The IUCN classify the Hanuman langur as Lower Risk.
