Who hasn’t groused about cleaning up bird droppings? The WhirlyBird Repeller promises relief.

The patented device catches the wind, causing it to spin, wobble and make a whirring and clacking sound, while reflecting light. The goal is to change the roosting and perching habits of birds to keep them off your boat, dock or deck. MSRP is $49.99, plus $10 shipping and handling.
