  • Patent number: 5191857
    Abstract: An electrical shock baffle for deterring squirrels and other animals from bird feeders, including a support for suspending the baffle, an open electronic circuit interconnected between a conductive portion of the baffle and a conductive portion of the support in order to render one of the conductive portions positively charged and the other of the conductive portions negatively charged so that an electrical shock will result when both the positively charged and negatively charged contacts are simultaneously engaged. The invention also involves the incorporation of the open electronic circuit into a bird feeder and a bird feeder including a bird exit opening and a quick release feed tray.

  • Patent number: 5150665
    Abstract: The bird feeder of this invention includes a reservoir which is generally conical in shape and having a plurality of feeding holes. A door is connected at the top of the reservoir and a conductive tray at the bottom. The conical shape provides a large opening through which the food may be poured. The conductive tray is connected by an electrical network to one or more of the conductive perches or trim mechanisms to form an open electrical circuit. The circuit is closed by contact with an animal to thereby provide a shock. The device further includes a baffle for separating the interior of the reservoir into independent compartments and trim mechanisms which are inserted into the feeding holes in order to vary the size of opening cooperating with the feed hole.
