The Challenge

It is estimated that hundreds of millions of birds are killed each year due to collisions with glass on human-built structures. Glass is reflective and transparent and is oftentimes not visible to birds.

Innovation Details

ORNILUX Bird Protection Glass is insulated, transparent glass designed to reduce bird collisions. The glass has a patterned, UV reflective coating that is visible to birds, but virtually transparent to the human eye, similar to spider webs. This helps to reduce bird collisions with glass buildings.

Biological Model

Some species of spiders incorporate UV-reflective silk strands into their webs. This attracts certain insects while simultaneously distracting or warning away larger animals, including birds. This is to the spider’s advantage, because if a bird were to fly through the web, the spider would temporarily lose its ability to capture prey.
