Aside pests and small insects, birds and rodents can be a farmer’s worst nightmare as they destroy crops and harvest.
Thus, farmers in the past relied on traditional scarecrows which comprised of a wooden-cross-structure covered in clothes to impersonate a human being. This scarecrow warded off hungry invaders.
However, today, with the emergence of technology, farm owners and managers are turning to high-tech devices with motion sensors to keep birds away from their crops.
After research led to the discovery that birds are sensitive to the color green, which is quite ironic since they usually dwell on trees, a researcher from Rhode Island helped design a laser scarecrow which projects green laser light.
The light isn’t visible by humans in sunlight but can shoot 600 feet across a field to startle birds before destroying crops. Early tests with laser scarecrow found that the device can minimize crop damages by reducing the bird population around farmlands by up to 70% to 90%.
