Bird-Safe Building Design

The Threat of Collisions

According to the American Bird Conservancy, up to a billion birds die in the U.S. each year due to glass collisions. Houston Audubon encourages bird-safe design as a way to address the significant threat of collisions to resident and migratory birds.

There are two main types of building-related threats to birds:

  1. Those that occur during the night during migration

Houston Audubon launched Lights Out for Birds for when high predicted migration through our region coincides with a weather front. We invite you to learn more about nocturnal migration and how the simple act of turning off lights can make a big difference for birds.

  1. Those that occur during the day throughout the year

During the day, birds collide with windows and buildings due to three key factors:



Site placement

Help at Home

Budget-friendly and effective options exist to help prevent bird collisions at home. Bird tape can be placed on windows to prevent collisions. Various other tapes and materials can be purchased and installed quickly.

Bird-Friendly Building Design

Most bird collisions occur on the first three stories of buildings. This makes sense because during the day, birds are foraging in the local landscape of grasses, water features, shrubs, and trees. Bird-safe principles are ideally integrated into any design plan, but numerous retro-fit options also exist. Fritted glass and visually appealing screens are two of our favorite options.
