Or he could be standing up to show you there's room for more winter padding so a few more nuts and treats would be nice. What a catch you got with your camera on this one, Milanie!
I'm waiting for a double backwards somersault just like they do in the Olympics what a neat pose! His feet are in the correct position for a fast takeoff....Awesome shot Milanie!
Oh, I love this, such a fun capture! The first thing that came to mind was, as @skskunky said, that it looks as if he's about to dive backwards into a swimming pool.
