Bird or Squirrel Feeder?

This bird feeder was wrecked by a squirrel chewing the bottom out of it. This was repaired by me with a chunk of plywood. The squirrel then struggled to find its way in to the nuts for several months. Yesterday a feeder full of nuts was emptied to the ground after the squirrel successfully chewed the plastic top apart. To the victor the spoils I suppose, Bird Feeder MkII coming up soon..
