I was thinking the magpie would top the pecking order too, but actually, no, the magpie is at the bottom. The squirrel and the rat both took a run at it when it got too close and saw it off. The squirrel is in the middle. And the rat is boss. It may be smaller than the others but it's an aggressive beast. Infringe its personal space and it makes like a torpedo. Every time this happened the squirrel gave ground.
