Colorado is home to three different species of cottontail rabbits, the mountain cotton tail, the desert cottontail, and the eastern cottontail. Almost everyone recognizes rabbits with their distinctive hopping gait and long ears. They are about 16 inches long and weigh about two pounds. Cottontails are smaller than jackrabbits and have shorter ears. The species of cottontails differ mostly by color and are difficult or impossible to distinguish in the field, except by habitat and geographic location.
