ABSTRACT:
The invention provides a pest deterrent apparatus for a tray-style bird feeder. The apparatus comprises a portable, self-contained source of high voltage that will produce a harmless electric shock for frightening away a pest such as a squirrel, cat, or other animal that comes into contact with the high voltage source. Shocking conductors are wired across the high voltage source so that a high voltage electric circuit is completed through the body of the pest when the pest comes into contact with the shocking conductors. The bird feeder is supported in such a way that it will tilt when a pest is on the feeder. A tilt-responsive switch means is operatively wired to the high voltage source for normally turning the high voltage source off and turning the high voltage source on in response to the tilting of the feeder caused by the weight of the pest on the bird feeder so as to close the switch, thereby giving the pest a harmless electric shock.
