Khush-Gai (Happy-Cow) Yak Poem by Sadiqullah Khan

The yak (Bos grunniens and Bos mutus) is a long-haired bovid found throughout the Himalaya region of south Central Asia, the Tibetan Plateau and as far north as Mongolia and Russia. Most yaks are domesticated, Bos grunniens. There is also a small, vulnerable population of wild yaks, Bos mutus. In the 1990s, a concerted effort was undertaken to help save the wild yak population.
The English word 'yak' derives from the Tibetan (Tibetan: གཡག་, Wylie: g.yag) , or gyag - in Tibetan this refers only to the male of the species, the female being called a dri or nak. In English, as in most other languages which have borrowed the word, 'yak' is usually used for both sexes. Wikipedia
