Yes, black bears do eat chipmunks as part of their varied, opportunistic diet. Black bears are omnivores, meaning they consume both plant and animal matter depending on what is available in their habitat. Their meals can include grasses, roots, berries, nuts, insects, fish, small mammals, and occasionally carrion. While chipmunks are not a primary food source, a black bear may catch and eat one if the opportunity arises, especially when other food is scarce.
