What do yaks eat exept grass?

Yaks are herbivores, so their diet primarily consists of plants. While grass forms a significant portion of their food intake, yaks also consume other types of vegetation depending on the availability and season. Here are some of the other things that yaks eat:

1. Shrubs and twigs: Yaks browse on shrubs, particularly during winter when grass is scarce. They can reach up to 1.8 meters (5.9 feet) high to access leaves, twigs, and branches.

2. Lichens and mosses: In high-altitude alpine environments, yaks may consume lichens and mosses that grow on rocks and tree trunks. These provide essential nutrients during harsh conditions when other food sources are limited.

3. Wildflowers and herbs: Yaks graze on a variety of wildflowers and herbs found in their habitats. They selectively choose nutritious and palatable plants, contributing to their overall dietary needs.

4. Fungi and mushrooms: Occasionally, yaks may consume fungi and mushrooms growing in their environment. These provide a source of carbohydrates, vitamins, and minerals.

5. Snow: In high-altitude regions, yaks are known to eat snow to supplement their water intake. This behavior helps them meet their hydration requirements during cold and snowy winters.

It's worth noting that the specific composition of a yak's diet can vary depending on the region and habitat where they live. Yaks are adaptable grazers and can thrive on a wide range of plant materials available to them.
