Your Sunday Squirrel

The hollow on this tree is a source of unending fascination for squirrels.  They love to stick their heads in it and rummage around.  They never find anything, but don't seem to remember that.  Right after I took this picture and gave this fellow a peanut, he was sticking his head in it to see if he had missed anything all those other times.  I guess they do this because they don't have television.
