Merriam's chipmunk is a small rodent with a striped back. It lives in the mountains and forests of California, runs fast, and collects food supplies.
Merriam's chipmunk differs from close species by the special arrangement of stripes and love for drier forests. It disperses plant seeds and serves as prey for snakes, birds, and predatory mammals.
