Bird-B-Gone Reflect A Bird Humane Bird Deterrent. It is a silent wind-powered spinning visual bird deterrent that effectively scares birds away. The Reflect-a-Bird's mirror-like design uses sunlight and wind to create a distraction zone that confuses pest-birds causing them to flee the area. The weatherproof aluminum and plastic construction make this bird deterrent ideal for outdoor use. For best results, use Reflect-a-Bird in conjunction with other visual or physical bird deterrents.
