Thanks for your compliments and suggestions.
I have an article here which mentions that in one year alone 30 Swifties died
hitting buildings. Doesn't say which year it was though.
What I am interested in specifically is any attempts to design buildings in a
way that minimizes the incidences of birds hitting buildings. Eg. I have an
article here that suggests that mounting glass windows on a 20 degree downward
angle helps, as do other less high tech methods such as putting stickers/decals
at particular intervals on windows.
My task is to come up with a list of methods that architects and builders can
incorporate into their buildings that will actually reduce the number of
It seems to me that there are 2 major issues - glass and light. We have
addressed lighting issues in other credits. Specifically with this credit I am
interested in addressing the glass.
Are you aware of any articles or other studies on the topic? Any leads you can
give me would be helpful.
I've copied this to Birding-Aus because I think perhaps I was not clear in my
last post as to what I am after.
Thanks again for the information.

Subject: Birds Crashing into Buildings
As a local (Bayside, Vic) Councillor I think the GBCA is doing a great
leadership job. At every opportunity I tell people your 5* is a genunine
international rating while the Victorian (BCA?) residential is just over 2
2*. And it only looks at energy efficiency, not materials locations.....
It makes me sick having to approve apartment buildings located to save 1
tonne pa of CO2e but with a design with no cross ventilation.... and built
of concrete which probably costs 9 tonnes more than it should.
Anyhow I am of course underqualified at almost everything. On windows my
impression is that there is a strong geographical element: in Hobart
everything should be done to minimise Swift Parrot impacts (including using
materials instead of wire netting around tennis courts). Around here the
most frequent reported casualty are Sacred Kingfishers, which fly quite low.
I know in the USA there are teams of birders who go around city streets
analysing mortality. It would be good to mobilise people to do the same in
our capital cities but I suspect (on thin evidence) that not many corpses
would be found.
The reason is that, as far as I know, we have very few regular (known)
migratory routes. And that is restricted to the White-naped and
Yellow-faced Honeyeater movement down the east coast (which does not
actually go to Sydney?). At a much lower (altitudinal level) are species
Not that we know what the effects of climate change will be on these
I've copied this to Birding-Aus so that I can learn what I've got wrong!
