Over the years I have seen several attempts by Common Mynahs to build
nests inside traffic-light housings. They carry in sticks and straws
and can make quite a large bundle - the housing is probably just the
right size. These attempts usually fail, because humans tend to remove
the nest materials so that the lights are not obscured.
As they usually choose the topmost, i.e. red light to build in, this has
led to a few photos in the local papers with predictable headlines
stressing the perils or raising young in a red-light district.
When we were in London, we were very surprised to find almost no
Sparrows and Starlings in Central London - and only a few in parks.
Older buildings were screened unobtrusively but thoroughly with netting,
as are Melbourne's Town Hall and State Library. Modern buildings offer
very few nooks and crannies. If this were done in our cities and towns,
would this reduce the introduced bird numbers - or would they just give
native birds more grief with even fiercer competition for nest-holes?
We could at least screen all the municipal palm trees which are always
full of roosting Starlings and Mynahs.

As usual Andrew beat me too it! I would add one point LEDs are
increasingly used in bird husbandry and a small byproduct is that
there limited heat output may be just sufficient to maintain an
ambient >30 degrees when confined to the nacelle. This is why Mynas
commonly use the heat exchanger of air-con units. It allows the
adults additional foraging time. Ciao

Bring back the old 150 Watt incandescents and roast the pests!
