Forget 'Games of Thrones', this incredible battle for territory is playing out every day on a bird feeder in Canada.
John Whyte sets up a camera to document the jaw-dropping skirmishes for tasty corn in his yard in Orillia, Ontario.
A chipmunk, black squirrel, ducks, crows and even a rabbit join in the royal rumble – sometimes to brutal effect.
John has named some of the returning participants, including Hector the crow and Eddie the chipmunk.
He says: "I have observed a particular pecking orders and how much even the smallest will risk for food."
