The big-eared woodrat is a rodent with very large ears. It lives in dry areas of California, builds houses from branches and feeds on plants.
The big-eared rat differs from related species by its very large ears and large nests made of sticks. It is important for nature as a spreader of plant seeds and food for predators.
