I have a solution...
Actually, a couple of solutions, depending on if you want to feed the squirrel, or leave him out. You could leave bird seed on the ground, to keep him there.
Or, you could keep him moving with a couple pumps from a BB gun, airsoft gun, or a blowgun. Foam Nerf darts in 1/2 inch pvc work well to startle the critter, but not injure it. They learn quickly, and soon they will be back to their natural state of scaring easily.
