The Wailers and the Flashing Hawkeye are particularly effective against pigeons and rooks on oil seed rape and other arable crops, with the Midi Wailer and Birdbuzzer being useful deterrents around cattle yards and silage areas.
Both varieties of deterrent have also been used with success around the world for protecting grapes in vineyards.
Game & fish farming
Experience has shown that for deterring predators such as buzzards and cormorants it is best to use visual means.
Both the wind powered Flashing Hawkeye (and the Buddha Eyes variant) and the Scarecrows have successfully protected free range poultry, pheasant release pens and fish farms whilst also being useful for protecting cover crops for game.
