Birds collide with glass because they see the world differently than people do. These collisions kill up to 1 billion birds each year in the United States, a conservation crisis that ABC is tackling head on.
Glass collisions take a staggering toll on birds, threatening common and rare species alike. Solving a problem of this size requires big thinking, bold ideas, and collective action.
ABC works on multiple fronts to reduce bird collisions, from advocating for collision-reducing legislation and evaluating new glass products to educating architects, developers, and homeowners and much more.
Together we can build a future in which glass is no longer a leading threat to birds.
If a bird has collided with your home, you are not alone as up to 1 billion birds die each year following window collisions in the United States. The good news is that you can install effective solutions to prevent future collisions.
Whether you want to reduce bird collisions at an existing building, design a new bird-friendly building, or promote bird-friendly building legislation, ABC has solutions.

ABC's collisions experts, Christine Sheppard, Ph.D., and Bryan Lenz, Ph.D., answer 14 of the most frequently asked questions about bird strikes.
Birds don't understand the concept of glass as an invisible barrier that can also be a mirror. They take what they see literally: Glass appears to be habitat they can fly into, whether that habitat is reflected or visible through glass.
ABC has developed a range of bird-friendly building resources, including a research bibliography, position papers, and more.
In the United States alone, up to one billion birds die from glass collisions annually. Learn how you can help prevent collisions today.
