This squirrel was not about to give up his tasty peanut butter sandwich that I had so kindly put in the suet feeder. I only did this out of desperation today to try to keep him off of the finches' thistle feeder. There is no such thing as a squirrel proof feeder!

I love him! And you're right about nothing can be squirrel-proof - we've watched some strange backyard antics here from the squirrels. Love how you got his expression and the composition is ideal.
