A flock of birds can damage acres of fresh produce.
“Not only can they eat the produce or eat your seedlings or your seeds, but they also poop in the field. So there could also be fecal material left behind,” said Paula Rivadeneira, University of Arizona professor at the Yuma Agricultural Center. “And that’s a real, genuine concern for food safety.”
To keep birds away, growers have tried more than just scarecrows – including cannons, noises that mimic predators and even lasers. Nothing really works.
