Ans - The golden langur is another rare species of animal. It is found in south-central Bhutan and north-western Assam. It is easy seen on the Bhutan side of the Manas River. It has a cream back which looks golden in good light and its sides are dark. Its face is black without any hair on it. It has a long tail with a tassel at the end. It is a shy animal and stays mostly in groups. In a group there may be as many as forty animals and their movements are controlled by a dominant male who moves first. They stay mostly on trees and descend to the ground only during the early hours of the morning or late in the evening to drink from a river or stream. They leap from tree to tree at the approach of man. Although the exact number of this animal is not known, it is believed that the population of golden langur is increasing in recent years. It is due to the efforts of the conservationists.
