Such ingenuity is the hallmark of the Airport Wildlife Hazards Program, who mix science, detective-work, and MacGyver-like problem-solving skills. They may also recommend the use of pyrotechnics, acoustic devices, propane cannons, and green lasers (which are especially scary to birds) to cope with avian interference. A less-common but hilarious intervention involves remote control cars, which are driven toward the birds until they’re sufficiently scattered. “Everything’s on the table,” Begier says. In about 10 percent of cases, agents will use lethal force, killing an animal before it has the chance to inflict further damage.
