Chipmunks have specialized cheek pouches lined with fur that can hold up to twice as much food as their stomachs. When they find food, they stuff it into their pouches and carry it back to a burrow or hiding spot.
When ready to eat, they empty the pouches by pushing food out with their tongues, then hold it in their front paws and eat it one bite at a time.
Chipmunks eat nuts, seeds, fruits, insects, and small vertebrates. They prefer foods like acorns, sunflower seeds, and peanuts, and they eat several times a day to maintain their energy.
