Squirrel in tree eating a nut

Here's another squirrel in a tree eating a nut. His friend was on another tree, peering around it at us, but I couldn't get a picture of him because he went up higher. But this fellow was so intent on his nut, that he didn't really care that Brownie and I were staring at him. He didn't move at all. But Brownie was ready to continue our walk, so this was the best picture I managed to get of him as the tugging on my other arm kept making my camera hand shake.
