As another resident of east Bris I agree with you Syd but considering
the numbers of Bats we have and see each evening the numbers killed are very low.

Not relevant, I know, but the biggest killer of bats here in Brisbane are the power lines. Nearly always one or more poor electrocuted flying foxes
hanging from the wires somewhere around the district.

Hi friends,

In an article in the New Scientist I recently received (12
May,2007,p.4), it
was reported that although wind turbines did not seem to cause
signficant
problem for birds, it has been found in the US that the main vitims of such
turbines are bats. The article speculated that possibly the high
frequency
noise from the turbine‚s gears might disrupt the bats‚ echolocation
system.
I find this very worrying. Any thoughts?
