I noticed this squirrel scampering around while photographing songbirds from a blind in my backyard. This fellow would grab some sunflower seeds that had fallen beneath a bird feeder and retreat behind an overturned deck chair. Then, he would peek out a few times and start over. Although squirrels can be a nuisance sometimes, this one turned out to be a great subject! :)

Perhaps you captured this a bit too big in frame...Very good sharpness and DOF. If he/she shows up more often, it might be worth to cover this area with a more natural setting, or create a nice perch.
