The Flock Reflector is a simple, inexpensive and durable option to provide bird control for a 50' area around where it is deployed (2,500 square feet). It is environmentally friendly as the movement is generated by harnessing the wind (moving the reflectors) and the deterrent effect of bright flashes is provide by the sun. The three parabolic cups move in even the lightest breeze, spinning around the central axis. As they spin, the curved surfaces catch, focus and reflect the sunlight, sending out blinding flashes of light which disorient and irritate birds. The unit is composed of aluminum and plastic and is weatherproof. The included mounting plate has 4 holes which can be used to mount this device in any orientation. NOTE: No mounting materials are provided but possibilities could include suction cups, screws, or adhesive.
