The vehicle-sider rear-view mirror mounted bird deterrent system delivers an electric shock to scare birds away. The bird deterrent system includes a shock strip, a sensor, a microcontroller, a power source, and a vehicle-side rear-view mirror. The vehicle-side rear-view mirror can be any rear-view mirror of a commercial or passenger vehicle. The shock strip is a thin flexible strip that attaches onto an exterior face of the vehicle-side rear-view mirror. The shock strip is positioned along the side rear-view mirror and covers most of the flat surface which the bird is likely to stand on. The sensor is operatively connected to the shock strip, wherein the sensor transmits a signal to the microcontroller when it detects a bird standing on the shock strip. The microcontroller completes a circuit between the power source and the shock strip, thereby creating a flow of electrical current capable of delivering an electrical shock.
