If you’ve got a problem with squirrels or other critters eating the food from your bird feeder, this squirrel flipper/bird feeder is a must! It is specially designed to detect the weight of a squirrel when it’s feeding, and at that moment it activates a spring which harmlessly flips the squirrel off of the feeder. The squirrels quickly learn that this is not a free meal and will head to your neighbors house to look for another bird feeder! Entertaining and safe for the squirrels, the manufacturers of this product go by the name of the Yankee Flipper. Note: The Surgeon General says that Squirrel Flipping is a safe alternative to Cow Tipping.
