City Buildings Dim Their Lights for Migrating Birds

Some of New York City’s iconic skyscrapers are joining a campaign to dim their lights this fall to help millions of migrating birds.

New York City Audobon says the lights can blind and confuse migrating birds. The organization estimates some 90,000 are killed in the city each year due to collisions with buildings.

The Empire State and Chrysler buildings, the Time Warner Center, Rockefeller Center and Worldwide Plaza have agreed to participate in the group's Lights Out New York campaign. They’ll turn off their lights from midnight to dawn during peak migration season, until October 31. As an added bonus, the group says participating buildings will save thousands of dollars on energy costs.
