Discovery of Bhutan Drukgyal Deer
The Drukgyal deer (Cervus unicolor himalayansis), a new deer (subspecies) to science was discovered in Thrumshingla National Park, central Bhutan by Dr. Pralad Yonzon and his 4 man Bhutanese team in 2002. It is different from both the sambar (Cervus unicolor) and the red deer (Cervus elaphus hanglu and C. e. wallichii) of the Himalaya, by having: 1) Skull with hexagonal plate, 2) white rump patch, 3) long rump hair, 4) a light brown tail with pale white edge and 5) closely set 3-tine antler. Its alarm call is high pitched bark against the sambar’s distinctive call. Its hexagonal plate-like skull is not found in the sambar. Other distinct cranial features are also described.
