Abstract:
A rodent-proof bird feeder for feeding birds, the feeder comprising:a feed holding container,a housing base upon which the feed holding container is mounted;electric motor having an output shaft, a motor mounting base juxtaposed to the housing base, the motor being mounted in the motor mounting base for reciprocative movement therewith;a power supply for powering the electric motor;a perch, the perch having coupling means coupling the perch to the electric motor output shaft;the coupling means including a resistance biasing means supporting the motor on the motor mounting base; anda switch means for energizing the motor, a switch contactor integral with the electric motor, the switch contactor energizing the switch means at predetermined times when the weight of an undesired animal upon the perch overcomes the resistance of the biasing means causing the electric motor to reciprocate within the motor mounting base and to compress the resistance biasing means to thereby rotate the output shaft and the coupled perch.
