Eastern Chipmunk Facts

Eastern Chipmunks (Tamias striatus) are common from Maine down through Florida. The get their name from a Native American Chippewa word that means “one who descends trees headlong.” They have a slough of predators, including but nearly limited to raptors, foxes, coyotes and weasels. They are primarily herbivores but will eat insects, worms and bird eggs. The pouches in their cheeks allow them to transport food to cache for winter. During winter they do not have enough fat reserves to hibernate, so instead they enter a state of torpor and their bodies essentially slow down and conserve energy. They do however, arise during the winter and occasionally forage for food. Eastern Chipmunks are very vocal and it is not uncommon to hear their thrill chips when hiking. The calls alert others of a potential predator in the area.
