Bengal Sacred Langur

The northern plains gray langur, also called the sacred, Bengal sacred or Hanuman langur, is mostly light in colour, with darker fur on the back and limbs and black on the face, ears, hands and feet. The body is 45–78 cm long without the tail, which measures 80–112 cm. Adult males weigh 16.9–19.5 kg and adult females 9.5–16.1 kg (Wikipedia, general species account).

Its range covers a large part of India south of the Himalayas, south to the Tapti and Krishna rivers. It is diurnal, both terrestrial and arboreal, eats primarily fruits and leaves, and often associates with chital deer. Groups may hold several males and females, one male and several females, or males only, and single-male groups are the most common; group size can exceed 100. Males usually leave the group where they are born, and gestation is about 200 days. A male taking over a group may kill infants fathered by the previous male (Wikipedia, general species account).
