When the folks at Droll Yankees sent me the new bottom for my feeder, I must admit, I was a bit skeptical. This one supposedly "flings" the squirrel off of the perches when they try to get onto it. It is run by a rechargeable battery and doesn't affect the birds at all. The weight of the squirrel sets it off.
I decided to take a "wait and see" attitude over the last week occasionally checking it to make sure that the squirrels weren't on it having a great time going around and around.
So far, so good.
My birds have been feasting undeterred and the food is not disappearing within one day anymore.
Ah, life is good.
