Protecting Crops with Sonic Nets
Birds cause crop losses worth hundreds of millions of dollars worldwide each year. In developed countries this is mostly a monetary loss, but in developing countries this loss can lead to starvation. Migratory birds are a significant problem because huge flocks can descend on a small area and totally devastate crops. There can also be a secondary affect as children are kept out of school and in the fields to act as human scare-crows.
Sonic Nets were developed to prevent crop loss due to birds in a humane way - birds are simply encouraged to leave - not injured or killed. Field trials have shown Sonic Nets to be an affective method of protecting crops.
