I swear this one squirrel is schizo. He jumps around like a rabbit, runs around in circles and rolls around on the ground. Then he'll dash up a maple tree to a skinny branch near the ground, climb out on the branch, turn upside down and crawl to the end of the branch until it bends to the ground. Then he lets go, falls to the ground, and looks up to watch the branch spring back up. Then he does it over and over, rolling on the ground in between his runs up the tree. I watched him do it 11 times in a row. This can't be normal behavior! He looks healthy enough, just acts weird.
