Fauna of Bhutan
Because of its unique setting & relatively un-exploited environment, Bhutan probably possesses the greatest biological diversity of any country of its size in Asia. It certainly contains some of the best remaining representatives of habitat types found in the Himalayas.
Along its southern border, the narrow tropical & subtropical belt supports the Asiatic elephant, greater one-horned rhinoceros, gaur, wild water buffalo, hog deer, tiger, clouded leopard, hornbill, trogon & other mammals & birds characteristic of indomalayan species. Only 150 kilometers to the north, high Himalayan fauna include the blue sheep, takin, musk deer, snow leopard, wolf & other species characteristic of the Palearctic realm.
So far as 770 species of birds have been recorded in Bhutan which reflects the Kingdom’s wide range of agro-ecological environments – from subtropical to alpine & its location at the northern edge of the Zoogeographical oriental region & the permeable & fluid border with China. Also country is famous for its over wintering populations (about 350 birds) of the vulnerable black-necked crane in the valleys of Phobjikha, Bomdeling & Gyetsa.
