On the way home, I looked over the seat to see how he was doing and he had definitely perked up.
It's been a while since I posted a squirrel picture so here are two shots of a squirrel on a big pine tree. His color is pretty good camouflage.
After he saw me, he went into his hole in the tree, but he kept looking out at me. No doubt he was hoping I would leave! Eventually I did, of course, and I suppose he went back out to gather some nuts.
