ROCKPORT, Mass. — Rockport residents have a history of fighting off invaders, but not this time.
During the War of 1812, townsfolk in the tiny fishing village hurled rocks at British soldiers using their stockings as slings. Now, they're slinging trash bags and towels over the side mirrors of their cars to protect them from a destructive and determined pileated woodpecker.
Over the last few weeks, the bird has broken more than two dozen mirrors and at least one vehicle's side window. But residents are taking the violence in stride.
''Everybody's having a good laugh about it,'' said Ben Favaloro. ''Nobody wants harm to the bird. He's always welcome back.''
Favaloro, who has lived in the neighborhood for nearly four decades, said he's seen the occasional woodpecker on the side of houses in years past and he removed several trees last summer that were damaged beyond recovery. But the attacking of glass is a new phenomenon.
''Initially, we just noticed that all the mirrors had been adjusted. It looked like maybe there's a child in the neighborhood that was going around pushing the mirrors down,'' he said. But then his sister-in-law spotted the roughly 21-inch (53-centimeter) tall woodpecker on Favaloro's truck, pecking at the side mirror.
Given their enormous size, piliated woodpeckers are plenty strong enough to break mirrors, but such behavior is ''definitely weird,'' said Pamela Hunt, senior biologist for avian conservation at the New Hampshire Audubon.
''Lots of birds will be aggressive against reflections in mirrors, but I don't usually hear about woodpeckers,'' she said. ''They don't usually peck at their opponents, they kind of chase them around.''
