Bird-Friendly Glass: Taking a Lesson From Spiders

Bird-Friendly Glass: Taking a Lesson From Spiders

THUD! You look around for the source of the sound and realize, with that sinking feeling in the pit of your stomach, it was a bird hitting a nearby window. Birds can't see glass, and therefore windows constitute one of the major causes of avian fatalities worldwide. To solve this problem, a German company is coming to the rescue of our feathered friends.

Taking a lesson from nature, and more specifically spiders, Arnold Glas has created Ornilux, which has a patterned UV reflective coating making it visible to birds while maintaining transparency to the human eye. This has been shown to reduce bird strikes by up to 75%. That number is impressive if you consider that at least 1 billion birds are killed in window collisions in the United States every year. Arnold Glas estimates another 250,000 per day in Europe.

First introduced in 2006, Ornilux has received numerous international awards. The most recent version, the Ornilux Mikado, has won a 2010 reddot "best of the best" award the Design Zentrum Nordrhein Westfalen in Essen, Germany. Praise goes to Arnold's designers and engineers for understanding that birds will avoid flying through a spider's web because it is made from a special UV-light reflecting silk.

The bird-protection glass also increases energy efficiency in buildings, as well as being more architecturally harmonious than stickers, whitewashing or netting.
