Automatic Squirrel-Ejecting Bird Feeder
This is the bird feeder that automatically spins when a squirrel’s weight rests on the feeder, gently but firmly flinging the squirrel safely away without harm and discouraging return visits (see the Bird Feeder in action). The mechanism is sensitive enough to allow finches, chickadees, and other lightweight songbirds to feed without spinning.
So says the sales pitch on the Hammacher Schlemmer website, where a RealPlayer video of the feeder in action may be viewed.
