Back Country Campsite Closed
Due to bear activity at Bryce Canyon's back-country, the following campsite has been closed until further notice: Sheep Creek
Common Name: Uinta Chipmunk
Scientific Name: Eutamius umbrinus
Size (length) English & Metric: 7.75"-9.5" (19-24 cm)
Habitat: All forest types
Diet: Nuts, seeds, fruits, & berries
Predators: hawks, jays, weasels, foxes, coyotes
The Uinta Chipmunk has wide and distinct dark brown or black stripes, the Least Chipmunk's dark stripes are narrow. The Cliff Chipmunk is the least colorful of the three species. It lacks any orange coloration and is mainly gray with faint, thin, black and white stripes. Bryce Canyon is also home to the Golden-mantled Ground Squirrel, often described as a "big fat chipmunk." This type of ground squirrel has similar markings to that of a chipmunk but with one major difference. All of the western chipmunks have a dark eye-line stripe across their faces, as if wearing a Zorro mask. No ground squirrels in North America have any facial stripes.
Biology & Behavior:
A general distinction between chipmunks and ground squirrels is that chipmunks are not true hibernators. To explain the difference in human terms, if you were a ground squirrel you would have to consume an extra six months worth of food during the summer, so you could spend the winter dozing on the couch. On the other hand, if you were a chipmunk, you'd spend the summer shopping for an extra six months of groceries and then make trips from the couch to the refrigerator all winter long. Instead of storing a winter's worth of fat on their bodies and going into a prolonged sleep, chipmunks make a food cache and wake periodically to eat from this stored food supply. Uinta Chipmunks are somewhat of an exception to this rule. In the fall, they not only cache food, but also fatten themselves up to better survive the winter.
The Uinta Chipmunk is considered a tree-dwelling species, which means although it spends lots of time on the ground, it nests and seeks refuge from predators in the trees. Uinta Chipmunks nest in the cavities of dead trees or hollow logs and have one litter of 2-5 offspring each spring.
