"Squirrel-Proof" Bird Feeder

We have a bird feeder on our deck that is supposed to be squirrel proof. If a squirrel sits on the ring at the bottom, his weight triggers a motor that spins the ring around. Birds are so light that they don't trigger the motor.

Recently, one of the many squirrels in our yard proved that trial-and-error works. He (or she) finally figured out how to hold on to the holes where the seed comes out. When he falls off, he eats the seed he has knocked off onto the deck.

My next step is to grease the outside with Crisco!
