The Tarai Hanuman Langur ( Semnopithecus hector ), also known as the Himalayan Hulman , is a species of primate from the slender monkey group and is one of the six species in which the subgenus Hanuman Langur belongs to the genus of Indian langurs ( Semnopithecus ) in more recent classifications.
features
Tarai Hanuman langurs are among the smaller Hanuman langurs, but resemble the other species in their slender body with the long tail. In a study in which, however, no distinction was made between Tarai Hanuman langurs and Nepalese Hanuman langurs ( S. schistaceus ), the animals had head-to-trunk lengths of 58 to 76 cm, a tail 75 to 99 cm long and weighed on average 17 kg. The long, dense fur of the Tarai Hanuman langurs is whitish-yellow in color, the back, arms, knees and tail are darker, more gray-yellow in color, the belly is white. The face is dark and hairless, as is the case with all representatives of its species, and is surrounded by a fringe of white hair. Hands and feet are light-colored. The tail, white at the end, is bent forward when walking on four feet.
Way of life
These primates live in the Terai region at the foot of the Himalayas in the Nepalese - Indian border region from Uttarakhand in the west to northern West Bengal in the east, possibly also to southwestern Bhutan . Their habitat are sal tree forests from 150 meters above sea level up to 1600 meters, the humid deciduous forests of the Siwaliks and oak and pine forests at the foot of the Himalayas. Tarai-Hanuman langurs, like all Hanuman langurs, are diurnal and live both in the trees and on the ground. They live in groups made up of several males and females as well as their offspring. They are herbivores that mainly eat leaves (over 60%). They also consume fruits (15%), buds and other plant material.
Danger
Tarai Hanuman langurs are an endangered species. The main reason for this is the destruction of their habitat by deforestation and mining, the IUCN lists them as " near threatened ". Protected areas where the species occurs are the Corbett and Rajaji National Parks .
