Realistic ‘moving’ predator head bobs along moving water. The Gator Guard® is a simple, easy, money-saving bird deterrent that floats on top of water as mirrored eyes catch the sun with 3-dimensional, 360° visibility; birds think they are being followed. Effectively scares off geese, herons, and other waterbird; it is an environmentally-safe, universal solution. With realistic markings and intimidating eyes, geese, ducks, and other waterfowl are sure to flee when they see this Gator Guard! It is effective worldwide – even where alligators don’t live – as this fear is instinctive, not learned. It is waterproof, weatherproof, and UV-resistant, which means no fading from the sun. Effective wherever visible, up to once acre of open space at 360°. Recommended for small bodies of water.
