Lights Out for Birds
Most North American migratory birds fly at night, and lights on buildings can disorient birds on their paths, resulting in fatal collisions. The Upper Texas Coast plays a key role on the Central Flyway, an important migratory path for birds. Birds that move along and across the Gulf of Mexico depend on safe passage through the Houston-Galveston area. Throughout migration, and particularly during storm fronts, turning Lights Out for Birds can make a difference.
Why Lights Out
- Migrating birds use the moon, stars, and electromagnetic fields to make their migratory trips successful
- About 70% of North American birds are migratory, and 80% of these species migrate at night. City Lights can cause birds to become disoriented which can lead to building collisions
- In the U.S. an estimated 340 million birds die from collisions with city buildings
- Weather fronts during migration can exacerbate the challenges faced by migratory birds on this already difficult journey.
What's Being Done
Houston Audubon’s Lights Out Action Alerts are distributed during times when high predicted migration through our region coincides with a weather front. By using Cornell Lab of Ornithology’s BirdCast program, Houston Audubon staff are able to track predicated migration levels and weather forecasts to make science-based determinations of when birds at the greatest risk of collision. Distributing these alerts can serve as a reminder for residents and businesses alike to turn off their lights for migratory birds.
