Innovative solutions to prevent birds dying at glass facades

Every year more than 100 million birds die at large glass fronts of office buildings or barriers of bridges and motorways.   

The birds try to get to the world beyond the glass and do not see the panes of glass as an obstacle, with fatal results.

LEARNING FROM NATURE

Spinne im Spinnennetz

The spider’s web is the starting point for solving this problem.

With their webs the spiders use the fact that birds can see UV light. The webs reflect the UV light so that they are a visible barrier for the birds’ eyes – and the spiders have successfully protected their webs from destruction by the birds.  

Two products are based on this concept: bird glass and bird marker.

Solution 1: Bird Glass

Based on the spiderīs web effect an insulated glass is coated so that it can be  perceived by the bird in the ultra violet spectrum. The coating is almost invisible to humans. The glas is patented and has won many awards, e.g. the Environmental Innovation Award and the Progress Award of the animal rights organisation PeTA.

The Glass can be used in all windows and facades. It is advisable to plan for bird glass with new developments. It is of course also possible to exchange the glass later.

    
Seen in daylight:
Hardly visible to human eyes.		   Seen under UV-light:
Quite visible for the bird`s eye.

The latest version of Bird Glass uses a chaotic pattern instead of stripes, which makes it almost invisible to the human eye. Only at a certain angle and with special UV cameras, the coating becomes sensitive, as our photos show.



Solution 2: Bird Pen

With the Bird Marker an additional visible layer for birds’ eyes can be applied to the glass fronts. Bird Marker is only suitable for private residential property as it is applied manually.
  • The additional layer must be applied to the outside of the glass after it has been thoroughly cleaned.
  • The stripes can be removed at all times with commercial window cleaner.  
  • Bird Marker can be purchased from our shop.

  



Solution 3: visible and invisible window decals

Window decals are often seen in the form of predators. The habituation effect is quite high, but experience shows, that four predator silhouettes per square metre window achieve a relatively good effect.

NEW: Invisible window decals

The commercially available window decals are quite noticable and not very nice on buildings. Therefore, decals have been developed which are only visible in the UV spectrum. The decals cannot be seenby the human eye, but the birds can see them. This is a true innovation, which you may order from our internet shop.

 



Solution 4: Birdscreens

Birdscreen protect birds from flying against window glass - without blocking the view. It consists of a fly-screen-like fiberglass micromesh, black top and bottom frames and can be attached to the top of the window by screw hooks or suction cup brackets.

Birdscreen works just like a fly screen. Birds can see the screen and will not fly against it. It can be adjusted to each window by cutting the fiberglass or adjusting the frames.

You may order Birdscreen in three different sizes directly in our Internet-Shop.

 

Birdscreen has been developed by leading ornithologists and is hardly visible - Can you see a difference?

Solution 5: Bird Film

The problem of bird collision is usually only appreciated when the facade is finished. Replacing the glass is not possible afterwards due to the high costs involved. Therefore, we provide film that can be applied retroactively. The film is however also visible to humans.

  



Solution 6: Bird Imprints e.g. for motorway noise barriers

Motorways, subway stations etc often have screens and noise barriers. These barriers can be deadly for birds. Very good protection can be achieved by regularly adding additional imprints.

We provide advice and a range of effective bird control products.

     


Solution 7: Acoustic pressure systems

Acoustic pressure systems emit ultrasound, which is not audible for humans. The acoustic pressure sources are discreetly placed on the building and protect the birds from clashing against the glass facade.
