Chipmunks have an omnivorous diet consisting of grain, nuts, fruit, berries, birds’ eggs, small frogs, fungi, worms, insects and on occasions small mammals like young mice. At the beginning of autumn, many species of chipmunk begin to stockpile these goods in their burrows, for winter. Cheek pouches allow chipmunks to carry multiple food items to their burrows for either storage or consumption. This little guy was really stuffing himself with these unsalted peanuts I baited him with. I took this on the steps in my front yard in Rockaway, NJ USA with my Nikon D3100 and the 70-300mm zoom lens.
