Chipmunk fight! 🐿🐿🐿 After collecting an impressive amount of nuts for the winter, one chipmunk must defend his stash from another. | Nature | PBS

Who needs fat bears when you have fat chipmunks? This blonde-color-phase chipmunk was caught stocking up for winter -- chipmunks have pouches in their cheeks that allow them to carry just a heck of a whole lot of food, to use the technical term, at one time. With the ability to stuff hundreds of seeds in its cheek pouches, a chipmunk's head can look twice as large as normal when they're stocking up on groceries! Thanks to Nick Fleck for sharing this video he captured at Lake Macbride State Park.
