Here's why:
* Diet: Grizzly bears are omnivores, meaning they eat both plants and animals. Their diet includes a wide variety of things, from berries and roots to fish, elk, and even carrion.
* Size: Pikas are small, roughly the size of a guinea pig. They would be a relatively easy meal for a grizzly bear.
* Habitat: Pikas and grizzly bears share some overlapping habitat, particularly in mountainous areas.
While grizzlies might not actively hunt pikas, they would certainly take the opportunity to eat one if they found one.
