DULUTH, Minn. - Dozens of migrating birds have died outside Minnesota Power's main office in downtown Duluth after crashing into the glass.
Bird experts tell the Duluth News Tribune the Bohemian waxwings might have become disoriented while feeding on dried berries on trees near the building.
Minnesota Power spokeswoman Amy Rutledge says it's never happened there before.
Building worker Tim Pohl says it was like a scene out of a horror movie. He says saw hundreds of birds flying and bouncing off the glass Monday. He says he picked up about 100 birds himself, and 37 of them died. He also says three crows gathered nearby to prey on the injured waxwings.
Minnesota Power plans to put stickers on the glass so birds will be more likely to see and avoid it.
