Bicyclists in eastern Oregon say they're getting whacked on the head by an angry bird.
Riders in Pendleton, Ore., told the East Oregonian that a male hawk is dive-bombing them because they're too close to a nest he's guarding in an old cottonwood tree.
Bicyclist Mack Temple says the bird came in from behind like a fighter plane and whacked his helmet. Another rider, Charlie Newhouse, says the attack on his helmet was "like getting hit with a baseball bat." He says the talons went in through the helmet.
Bird-watchers say the large bird is a Swainson's hawk. The riders say he's been vigilant for a few nesting seasons, but hasn't been as aggressive as this year.
Bird-watchers say the hawk will ease up once his brood learns to fly.
