Psycho Squirrel

That morning I went outside to see what the racket was all about. It sounded as if some bird was making a lot of noise, I thought perhaps there was some predator about and went out to see what it was.

I saw no predator, but I saw that the weird bird noises were coming from this squirrel. It was up on a branch, staring at nothing, and making these weird noises. It did it for at least an hour then vanished. Not sure what was up with that, maybe he had eaten something he didnt like?
