Earth Hour: Turning Lights Off Reduces Greenhouse Emissions, Protects Migratory Birds
American Bird Conservancy Says: Please Keep Them Off during Spring and Fall Migration

(Washington, D.C.) American Bird Conservancy supports Earth Hour 2009, www.earthhour.org, the worldwide movement to turn out lights for one hour on March 28th from 8:30-9:30 p.m. to send a powerful message about the need for action to combat global warming.

“Turning out your lights will save energy, reduce greenhouse gas emissions, and benefit migratory birds during spring migration,” said Darin Schroeder, American Bird Conservancy’s Vice President for Conservation Advocacy. “Earth Hour doesn’t have to be a one-day event. Many North American cities such as Chicago, Toronto, Minneapolis/St. Paul, and Detroit have initiated ongoing Lights-Out programs to reduce greenhouse emissions, save money, and protect migrating birds.”

The bulk of spring migration dates from mid-March through June, while fall migration begins in mid-August, and extends through October. Many migratory birds fly at night, and when they are killed by collisions with large buildings and other structures, it is because of light. Birds evolved over millions of years to navigate their migration routes in dark skies, greatly aided by the light of the stars and moon to orient themselves on these flights. Starlight is made vastly less visible by the light pollution from our towns and cities, and thus interferes with the birds’ ability to reach their destinations safely.

“Unfortunately, the artificial lights of our cities and towns present a serious hazard to migratory birds, particularly during times of low cloud cover and inclement weather,” said Schroeder. “Birds become attracted to lit structures, and are disoriented by these lights and often end up colliding with them or with other birds leading to their injury and death. Many such catastrophes have been documented, the worst incidents involving hundreds of birds killed at one building in a single night.”

Turning out lights, particularly on tall office buildings and apartments can make a dramatic difference for birds, reducing bird kills by eighty percent. The before and after photographs of Chicago, (before and after 11 p.m. when downtown skyscrapers dim their lights during spring and fall migration), illustrate the difference the Lights Out Chicago program makes.

“Everyone can help by extending their participation in Earth Hour to include turning out unnecessary lights for the duration of the night, particularly during periods of spring and fall migration,” said Schroeder. “If you live in an apartment building or work in an office building, talk to the building management about turning off exterior flood lighting from night time until dawn, and encouraging residents to draw their blinds at night.”
