Lights Out to Save Birds

Ask,  Mar 2004  

Have you seen a city skyline at night? The lights can look like twinkling stars. It's pretty for people, but a big problem for birds.

Many songbirds migrate at night, when predators sleep and winds die down. These birds use the stars to navigate, and the bright lights of city skyscrapers can throw them off course. Confused by the lights, some birds circle buildings until they're too tired to fly, while others crash into the brightly lit windows. In just one night, thousands of birds can die.

To help keep birds on course, big buildings in some cities have started turning off their lights during spring and fall migrations. That's great news for millions of birds. According to a recent study, keeping buildings dark at night can reduce the number of birds killed by 80 percent.
