Cottontail rabbits are members of the lagomorph family. Hares and pika are the other lagomorphs in Yellowstone. The hares native here are the white tailed jackrabbit and the snowshoe hare, which are larger than the cottontail and become white in the winter. The cottontail remains brown and gray. They are vegetarian and shy, living in the lower elevations of Yellowstone in brushy areas.
