What behavioral adaptations does a caribou have?

Caribou exhibit several behavioral adaptations that help them survive in their harsh Arctic and sub-Arctic environments. They are known to migrate long distances, traveling hundreds of miles to find food and suitable calving grounds. During the winter, they dig through the snow to access lichens, their primary food source, and they often graze in groups to enhance protection from predators. Additionally, caribou have a unique social structure, forming herds that provide safety in numbers during migration and calving seasons.
