Isn't it cute? If you've never met a squirrel in real life you'd be surprised how protective they are over their nuts. Have you ever seen any of the Pixar animations with Scrat, the saber-toothed squirrel? This little fellow behaved just like Scrat when I approached to get a better photo. It dashed away as quickly as it could before I could even think of wrestling that yummy nut away. :)
