The perch is coupled to the electric motor and the electric motor is reciprocatively mounted in the bird feeder so that when a rodent 47 of excessive weight alights upon the perch the motor is pulled against a resistance spring 41 and a switch 38 is caused to close, thereby engaging the motor which rotates the perch to dislodge the rodent therefrom.
