Iowans urged to turn off lights to help birds migrate safely

• Over 80% of birds in North America migrate overnight, but light pollution from homes, businesses and sports stadiums can confuse them, resulting in fatal collisions with windows and buildings.

How you can help: Turn off your lights between 11pm and 6am.

• If that's not an option, consider changing your light colors from cool to warm or diverting them downwards to limit pollution into the sky.

What's next: If you find an injured bird, contact a local wildlife rehabber.
