I saw this squirrel running across the grass, then got my camera out and caught the first photo as it ran up the side of a tree and paused, looking at me as if assessing whether I was a threat or not. Then it ran the rest of the way up to look at a gap in the tree, perhaps assuring itself that its stash was still where it had left it. I walked around to see that there was a hollow between the two major branches, and the squirrel turned around and planted itself firmly, staring at me as if ready to defend its hoard.
My photos taken, I walked away.
