World-famous Chicago landmarks such as the Sears Tower and the John Hancock building are dimming lights that confuse migrating birds and cause them to crash into windows.
"The point is to attract less attention at night ? not from people, but from birds. From the song sparrow to the hermit thrush to the Baltimore oriole, birds migrating from the south in the spring and from the north in the fall are attracted by the lights of buildings, apparently confusing a light bulb with the stars that they navigate by. And too often, ornithologists say, the birds smash into the windows and wind up dead or seriously injured."
