Abstract
A bird feeder equipped with an electrically powered spinning mechanism that is triggered by the weight of a squirrel on the feeder is described. Upon detection of a squirrel on the feeder, the spinning mechanism rotates the feeder at a rate adequate to centrifugally remove the invading squirrel while resulting in a minimum loss of feed contained in the feeder.
