The wild yak is a big cattle endemic to the Himalayas and is scientifically known as Bos mutus.
It is the progenitor of the domestic Yak (Bos Grunniens).
The yak faces threats from several origins, of which commercial poaching is most prominent.
It mostly affects male yaks because they are more solitary.
Another threat facing this species is breeding with other livestock herds.
This doesn’t exclude the contacting of cattle-borne illnesses, although there is no direct proof to corroborate this.
Many Yaks can be seen in game reserves, especially in China.
Yaks can be found in Northern Tibet and the western region of Qinghai.
Some of their populations spread to the extreme southern regions of Xinjiang and Ladakh in India.
This animal is prominent in Nepal and even printed on the nation’s currency.

Size and Description
Yaks are one of the biggest but extant bovid species, and they also happen to be the biggest animal in their territory. Fully grown wild yaks range from 5 to 7 feet tall. Their weight ranges from 305 – 1200 kilograms.
The length of their body and head is between 2.5 to 3.4 meters. Their tails are quite long and within the range of 24 to 39 inches.
Female yaks are less sizeable than their male counterparts. They are lighter and smaller than the bulls. The domestic yaks are slightly smaller than their wild counterparts as well.
Yaks are powerfully built beasts with a massive frame, solid legs, and rounded hooves. Their udder and scrotum are covered in hair to protect against cold weather.
The female yaks have four teats, while both genders have long, rough-looking hair. Their body is insulated against cold weather thanks to the thick woolen undercoat. This undercoat covers the chest, flanks, and thigh areas.
This undercoat is so long that it can form a skirt around the yak’s body and even touch the ground. Yaks have a long tail that is lengthy and horse-like instead of having tufts like a bison.
Their extensive coat is usually dark brown or black.
Habits
Yaks move in herds, and a single herd can contain several hundred yaks,, although some are not that large.
The herd mostly comprises female yaks, the offspring, and a small number of males (bulls). The female yaks graze on surfaces much higher than the males graze.
Male yaks are alone or found in smaller groups with about six bulls. Yaks dread contact with humans and might run away when approached. They can also become vicious during the rut or while protecting their offspring.
Diet
The wild yaks primarily feed on grasses and sedges such as Stipa, Carex, and Kobresia. They also feed on herbs, winter-fat shrubs, mosses, and, in some cases, lichen. They are mainly preyed on by the Himalayan wolf, snow leopards, and brown bears.
Habitat
Yaks prefer treeless highlands ranging between 9,800 and 18,000 feet, which are mountains and plateaus. They are typically found in alpine tundra with a slightly thick carpet of sedges and grasses.
Reproduction
The yaks breed during the summer season and deliver their offspring during spring. They usually give birth to a single calf, and the female yaks typically give birth once a year.
Relationship With Humans
The yak is an organic reservoir for bacterial and viral, animal-based ailments. This could include ailments like anthrax, botulism, tuberculosis, and tetanus, which have been severely affecting humans.
Conservation Status
Yaks are regarded as a vulnerable species by the IUCN. Its previous status was endangered, but this was due to population decline years earlier. A more recent population study estimated them at about 10,000 adult yaks.
