Hi Chris,
I've been doing quite a lot of research into this topic over the last two
years as part of my consultancy work. The most authoritative source of
information is the following scientific paper:
Klem Jr, Dan (2009). Preventing bird-window collisions. The Wilson Journal
of Ornithology 121 (2): 314-321.
www.windowcollisions.info/public/klem_preventing_2009_e.pdf.
UV light is visible to birds but not to humans. Therefore, the most
effective means of reducing the incidence of bird-window collisions is the
use of glass panes that are coated on one side with a UV-reflective or
UV-absorptive film. You can also purchase UV-reflective decals that can be
adhered to window panes, which are barely visible to humans, but very
visible to birds.
Anthea's suggestion of retaining a film of dust/dirt on windows is also
quite effective. I first learnt about this in the early 1980s when I was
doing my Ph.D research at the Eyre Bird Observatory. The wardens, Peter & Di
Congreve never had birds hitting the large kitchen or living room windows
because the windows were seldom cleaned. I've since ensured that large
windows in homes that I've lived in are completely clean and I've never
observed birds colliding with them or attacking their reflections.
Kind regards,
Stephen

G'day all,
Just tossing around some ideas today for devices that might
prevent birds from flying into windows.
I wonder if anyone has come across anything that has worked in preventing
this.
Any ideas or suggestions will be gratefully received.
Cheers,
Chris Watson
