Did you know that most birds migrate at night? They often use the moon, stars, and sun to navigate. Light pollution can interfere with these signals and cause a serious problem for birds: they might be thrown off course or become so disoriented that they circle until they fall to exhaustion or collide with buildings. You can help with just a flick of a switch – plus you’ll save money on energy costs!

  • Turn off lights at night on unoccupied floors and in unused spaces.
  • Close curtains and blinds.
  • Turn off exterior floodlights during bird migration season.
  • Opt for shielded lighting that directs lights downward.
  • Try using task lighting at your workstation instead of overhead lights if you’re working late.
