"I love squirrels, but bird food is expensive. Those little fuzz brains are pure artists, when comes plotting problem solutions. You can see them think and evaluating the situation. They are also not giving up easily, when they fail at their first attempt; and they learn as they go - very admirable!You can turn any hanging bird feeder into a DeFeeder, at a very minimal price, if you can create the right conditions. The squirrels will still get enough food from the seeds, the birds are throwing overboard. I assure can you, no squirrel has been harmed in my attempt to keep them out of my bird feeder. "
