Glass collisions: It's a huge problem for birds. Up to a billion birds die in collisions with glass each year in the United States. Although most people have seen or heard a bird hit a window, they often believe it is an unusual event. Add up all those deaths and the number is staggering.

Both common and rare bird species hit windows. According to a 2014 study, species commonly reported in glass collisions include White-throated Sparrow and Dark-eyed Junco. Ruby-throated Hummingbirds are frequent victims, along with Wood Thrush and other species of conservation concern.

Within our work to eliminate threats to birds, we are proud to be the first organization to take a national approach to solving the glass collisions problem. We educate and inform architects, planners, and developers about the issue and solutions. We also advocate for legislation to require use of bird-friendly materials, and we develop and evaluate new materials. In addition, we have also produced a fact sheet on quick and inexpensive ways that homeowners can birdproof their windows, available in English, Spanish, or Portuguese.

Our Bird-Smart Glass Program provides proven tested products for every conceivable need, from those of architects and builders to homeowners.
