The Hawk Bird Scarer is a full size replica hawk moulded from tough weather-proof plastic with imitation wing tips that flap when the bird is suspended. No power, wind or poison needed – environmentally friendly. One Hawk Bird Scarer would be suitable for the domestic back garden or pleasure craft. Suspending on a pole or guide-wire between 2 trees has the best effect. Effective against most birds such as starlings, mynas, pigeons, swallows, seagulls, ducks but does not give 100% results for sparrows.
