There must be a way in somehow

Today, we had several Squirrels in the garden at one time and this one appeared to be other than our regular visitors.  The Squirrel could see the peanuts inside this bird feeder and was absolutely determined to try and get to them, while one of our local Squirrels was happily feeding on the Squirrel box.  The visiting Squirrel tried everything he could think of to get to the nuts in this feeder, he examined it from top to bottom, hung upside down on it and even wrapped himself around it; all to no avail.  The final blow for him came, when out normal resident Squirrel refused to let him eat from the Squirrel nut box.  No doubt he will return when our resident Squirrel is not present.
