<p>John Swaddle and Mark Hinders of The College of William and Mary in the U.S. will design and test controlled "nets" of sound that block vocal communication and hearing in pest bird species, causing them to move to other areas where they can hear each other and predators. Driving these pests away from crop areas should substantially reduce crop losses.</p>
