- Wild yaks travel in herds forming a single line led by the alpha yak. The rest of the yaks follow the exact footsteps of the leader.
- Males and females yaks are either found alone or staying in the same-sex herd. Female yaks stay on higher slopes (at least 1000 meters) than males.
- Yaks often huddle together while confronting a predator. Those who are in the front, lower their horns to scare the enemy.
- During the winter season, yaks consume snow for hydrating themselves while during summer months, they drink plenty of water.
Mating & Reproduction
Throughout the months of July and September, adult male yaks produce grunts and find their mates. They also become hostile during the phase. After the mating, followed by a gestation period of 258-270 days, female yaks give birth to one calf in April-June.
Calves learn to stand right away and walk within a couple of hours. They remain dependent on their mothers for feeding and other stuff for 1 year. By the age of 2, they become all grown up. While males attain sexual maturity around 6 years of age females are capable of breeding at an early age of 3.
- Wild yaks having golden hairs are named wild golden yak and according to Chinese
peoplethey are the endangered subspecies of wild yak.
