Birds become confused by bright lights and can lose their way. Many crash into brightly lit skyscrapers and become injured or die. Depending on the weather, tens of thousands of birds can fly over Chicago in a single night. As some building owners know, a hundred birds might be killed at one building on a night of heavy migration. To reduce mortality rates during migration seasons, area bird conservation organizations recommend the following:

1. Talk to your building manager about turning off the building's lights between the two migratory seasons: (1) mid-March to early June and (2) late August to late October.
   
2. Lower or turn off exterior decorative lights.
   
3. Review the Call for Action! flyer.
   
4. Install motion-sensitive lighting.
   
5. Use desk lamps and task lighting instead of overhead lights.
   
6. Schedule cleaning to reduce the amount of time lights are needed.
   
7. Re-program timers to fit hours of operation and cleaning.
   
8. Use lower-intensity lighting.
   
9. Reduce perimeter lighting.
   
10. Use solar reflective blinds or curtains.
