I met some groups of the rare and very endangered Golden Langurs in Bhutan while visiting the Zhemgang area. It is a mountainous country with lush forests where they like to jump from tree to tree.
The construction of bridges on the rivers allowing the langurs to cross on the other sides has caused a hybridization process between golden Langurs and capped Langurs leading to a future disappearance of the Golden Langur species in a near future.
