"It was like an Alfred Hitchcock movie," worker Denise Wilkinson said. "It was spooky. You could hear them where they flew into the glass."
Warm weather and an ample supply of berries attracted hundreds of cedar waxwings into the enclosed courtyard of the three-story building Tuesday,
The birds began getting drunk on the berries. They got so loopy that some were falling off branches and others were slamming into the glass walls that enclose the courtyard, said Burgess Mills, the building's owner.
About half of the 100 birds that slammed into the building died, workers said.
Groundskeepers have tried to help the birds by putting tape on windows or nets over the holly trees to keep them from eating the berries, Mills said.
