OCEAN CITY, N.J. — They are deft predators of the French fried potato, able to pluck a fresh wedge in the milliseconds it takes a single fry to travel from its container to a human mouth.

Though gulls are as core to the Jersey Shore as a stereo blasting “Born to Run,” the birds that have been hunting the food stalls lining the boardwalk in Ocean City possess an extra level of voracious hunger, a fever pitch of aggression that stands out even in a state where pugnacity is considered a plus.

Their behavior has turned this popular oceanfront destination into a Hitchcockian dystopia of divebombing birds.

“I’ve seen them take on an entire pizza,” said Tom Baglini, 71, who lives in Ocean City with his wife, JoAnn. “I saw the guy and he had the box, and he took one slice out, and the bird came down, hit the slice, then hit the box, and the pie hit the ground, and then, like hundreds of birds just swarmed.”
