Canberra's glass structures and bird strike

[Shazzam M via Canberrabirds <>]

It may not be aesthetically pleasing - or perhaps could be with the right design - vertical stripes on glass can deter birds from flying into glass - simply because they realise their wing span has limits - see attached video - hoping it is of some use/value. Perhaps a pattern glass would help?

Anti-reflective Window Films

Antireflective vinyl or polyester films to apply to the exterior of a window to make it visible to birds.

Covers the entire exterior surface of a window, reducing its reflectivity and transparency substantially, while thousands of small perforations in the film allow light to pass through to the interior. Ten percent of the purchase goes to the Fatal Light Awareness Program (FLAP) to help fund research to reduce bird-window collisions. Can be custom-printed.

“Glass art for windows,” these patterned films stick to any smooth surface, decrease glare and UV light, and reduce reflections and the illusion of clear passage. Take care to select a design that offers adequate coverage.

Thoughts?  While I might have overlooked some relevant research, it seems to me that the aim of the flying bird is not to enter the comfortable gas-warmed interior of a Canberra house, or to take advantage of the swimming pool, or the bus shelter in the below example, being deceived by the transparency of the glass, but is, rather, to enter the world of sky, vegetation and bird-friendly habitat that is reflected by the glass.  If that is so, frosting might not be an effective preventive measure, if the illusion of a different world behind the glass is maintained.  A window is still reflective even if there is an opaque curtain behind it.

 

Yes, David, there is quite a lot of glass being incorporated in new structures in Canberra suburbs.  It is not just a preference for the material in contemporary architecture but the sheer volume of building taking place, as you will find if you take a drive through the expansive Lower Molonglo developments.

Subject: [Canberrabirds] Canberra's glass structures and bird strike

 

Greetings. Yesterday had a call from a resident of Kambah, who found my contact details at COG’s website.

 

She is a very environmentally-sensitive person, and asked if COG, or any other environmentally-focused organisations, are aware of an increasing number of deaths of birds caused by them flying into glass structures. She points out that it seems to have become increasingly fashionable to have all kinds of structures made out of clear glass, instancing glass railings on balconies and glass fencing around swimming pools.

 

Another example she provided is that one of Canberra's prominent private schools has recently installed a large, clear glass, bus shelter. At the foot of it she found one or more birds that had been killed there by flying into the glass. To their credit, it seems that the school has responded to her concerns by undertaking to frost the glass.

 

Not spending much time in Canberra nowadays, I'm not in a position to assess the extent to which clear glass structures are increasingly being constructed in the city. Nonetheless, if that is the case, perhaps there is scope for planning regulations to take into account the danger of bird deaths from flying into clear glass structures? Thoughts and experiences?

 

Best wishes – David
