Curses! Foiled Again!

This is the only bird feeder that is truly squirrel proof.  They have pretty much given up attempts to get seeds but every now and then a squirrel will give it another go.  Their weight on the cage part automatically closes it.  This little one is trying to figure out why he can't reach the seeds.  He tried again and again but no luck. This line came to mind, Insanity is doing the same thing over and over and expecting a different result.  Actually, I think that better applies to humans than squirrels.
