On NYC beaches, angry birds fight drones patrolling for sharks and struggling swimmers
Patrol drones deployed in May to New York City beaches to look for sharks and struggling swimmers are ruffling feathers. Seabirds have been attacking the drones as if they are predators, flying and swooping at the machines while vocalizing.
