Grey Squirrel (Sciurus carolinensis)

I was hunting for adders this morning (one half-decent shot of a male will be posted later) when I heard the tell-tale sound of a squirrel discarding unwanted parts of acorns and dropping them noisily to the ground. When I spotted this female she was some distance away, but at a good height for a pleasing composition. I particularly like the animated eyes, the cradling of the acorn in surprisingly delicate claws and the way the bushy end of the animal's tail is visible below the branch she is perched upon.
