The Hawk Bird Scarer is a full size replica hawk molded from tough weather-proof plastic with imitation wing tips that flap when the bird is suspended. Originally invented to scare seagulls and shags off boats, yachts and wharves. Protect your crops such as stone, pome fruits, nuts, berry or broad-acre crops on calm or windy days as you suspend your hawk over or near your crop. No power, wind or poison needed – environmentally friendly. One Hawk Bird Scarer would be suitable for the domestic back garden or pleasure craft, more would be needed for a large commercial crop. Ideally, when suspended freely from high trees, two Bird Scarers will effectively keep 2ha free of any major bird damage, more may be needed depending on each situation/circumstance. On a pole or guide-wire between 2 trees have the best effect. Effective against most birds such as starlings, mynahs, pigeons, swallows, seagulls, ducks but does not give 100% results for sparrows. If the problem birds are already nesting then it is too late to use this device to stop them nesting – But the Hawk will stop them from nesting next season if the Hawk is installed before the nesting process starts.
