Characteristics

The yak is a large, horned bovid. They generally have shaggy brown or black fur. Both male and female yaks have a pronounced hump over their shoulders.

Yaks are well-adapted to live in mountainous areas; they have long fur to keep them warm and large lungs to help them to absorb oxygen at high altitudes.

Due to their strength, yaks are often used to transport goods (and people) across mountain passes. Farmers also use yaks to draw ploughs.

Yaks breed in the summer. As the rut (mating season) approaches, males become increasingly more aggressive towards and will often fight with one another to establish dominance.

Female usually breed for the first time when they are 3 or 4 years old. The gestation period in yaks is between 257 and 270 days. Females typically give birth to a single calf. The calf is able to walk within minutes of being born but does not become fully independent until it is over a year old.
