Yak

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The yak, Bos grunniens, is a long-haired bovine found throughout the Himalayan region of south Central Asia, the Tibetan Plateau and as far north as Mongolia. In addition to a large domestic population, there is a small, vulnerable wild yak population. The English word "yak" derives from the Tibetan, 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. Yaks belong to the genus Bos, and are therefore closely related to cattle (Bos primigenius), with whom they commonly interbreed, as well as to other Bos species, including the Southeast Asian banteng, the gaur, and the extremely rare kouprey.
