ABSTRACT:
A squirrel proof bird feeder including an electrical deterrent to deny squirrels access to a bird feeding station. The squirrel proof bird feeder comprises a bird feeding station, a conductive support pole attached to the bird feeder at one end and embedded within the ground at an opposing end, and a conducting plate affixed to, but electrically isolated from, the conductive support pole, and a regulating power supply providing electrical shock stimuli to animals contacting the conductive plate member and any earth ground, and more particularly the conductive support pole. In an alternate embodiment a plurality of isolated conductive plates are employed to provide a range of heights for the purpose of shocking a corresponding range of animal sizes. Yet another alternate embodiment employs a sensor which detects the imminent approach of an animal and activates the electrical p[power supply deterrent only when animals are present.
