Help Prevent Avian Deaths
Mitigate Damage to Windows
Invisible markings change the reflectivity of glass to make birds redirect their flight pattern.
Bird Collisions Into Windows Can Be Deadly
Windows of any size pose a threat to birds. However, structures with larger surface areas of windows present the most danger to avian populations simply because there is more glass to create potential collisions. For decades, Dr. Daniel Klem has studied the impact of both commercial and residential structures’ windows on avian populations. He estimates between 100 million and 1 billion bird deaths occur annually in the United States as a result of window collisions.
Why Do Birds Fly into Glass?
It is estimated that up to one billion birds die annually in the United States as a result of flying into glass. The reason is that birds can’t see glass. In fact, neither can people, but people can rely on visual cues such as the presence of window frames and door handles to know of its presence. Unfortunately, birds cannot. Birds also perceive scenery reflected in glass as real and fly into a window in an effort to reach it.
Nearly Invisible Bird Divert Helps Prevent Collisions to Improve Bird Safety
Retrofitting buildings with Bird Divert avian window film can help mitigate bird collisions into exterior glass surfaces. Invisible (to the human eye) circles signal the presence of a glass pane to birds. The markings break up the reflection of surrounding vegetation and the sky, reducing the occurrence of birds flying into the glass. In addition to protecting birds, outfitting windows with bird safety markers help shield a property from damage. While a small sparrow might not leave much of a mark, a bald eagle can certainly cause an impact.
What We See
What Birds See
Bird Divert has been tested by the American Bird Conservancy (ABC) and achieved a threat factor of 18. According to ABC, threat factors indicate the relative ability of materials to reduce avian collisions. Products with lower threat factors are considered more effective at preventing bird collisions. A threat factor of 30 should reduce collisions by at least 50% and is ABC's upper threshold for categorizing materials as bird friendly. Learn more about Threat Factors here.
