Lights Out

Here’s how you can make a difference!

Building owners, businesses, and developers can help protect migrating birds passing through Houston by turning off all non-essential nighttime lighting on buildings from 7:00 p.m. to 7:00 a.m. each night April 19 through May 7 – the critical Spring period for nocturnal bird migration[1]. With your help, we can dramatically reduce the hazards posed by light pollution in Houston and allow birds to resume their typical migratory behaviors[2].

What we need you to do:

  • Join us by committing to turn lights off from 7:00 p.m. to 7:00 a.m. during this critical migration period.
  • Talk with other local stakeholders and get them to join the movement, too!
  • Share your support for the cause via social media and with local media.
