In the historic battle of birds versus farmers, there’s a new hi-tech scarecrow in town.
Bird Control Group, a Netherlands-based firm, is selling a laser in the US that imitates predators to scare off birds. The Agrilaser Autonomic, as it’s called, is installed near crops and combines colours, filters and lenses to produce a greenish laser beam about 3 inches (7.6cm) in diameter. Birds perceive the back-and-forth motion of the laser as a physical danger, like a predator or an oncoming car, and instinctively take flight to seek safety, chief executive officer Steinar Henskes said.
