Texas is a major flyway for migrating birds. Outdoor lighting can be deadly for the wildbirds who mostly travel by night. The lights distract and disorient them leading to exhaustion and building collisions. Houston and Dallas are ranked in the top three most dangerous cities for migrating birds.

Building owners, businesses, developers and homeowners can help protect migrating birds by turning off all non-essential nighttime lighting on buildings and other structures from 11 p.m. to 6 a.m. each night. 

Migration season runs March 1-June 15. Peak migration is April 22-May 12.
