Thank you all for your replies. I'm encouraged
to hear that there really isn't a problem with turbines killing birds.
I'd never heard of a bat killing issue
before. Has anyone heard any information, pro or con, about that issue?
Thanks
Drake

Drake,
There is nothing to it that is documented and
recent. There were some problems years ago (20
30) due to tower design and poor placement.
The towers are a different design and it was
never a serious issue in any case. Years ago the
towers were a freestanding design with many
places to perch and look for game to pick off
for lunch. Rotor diameter is also considerably
larger and slower now. Something like 20 rpm vs.
200 rpm. I have watched black birds chase a hawk
through the sweeping rotor for 10 -15 minutes,
no problems. It might have been the hawk leading
the black birds through the rotor. Either way it
was fun and fascinating to watch! I think I
videotaped it but it was years ago and I have no idea where it might be.
My house windows, cat and car get MANY more
birds than my turbine ever has. The cat and car
do fairly well, when birds fly into the windows
it is loud and not good for the birds at all. I
have never found a dead bird under any of the turbines that I service.
I did find a dead bird in its nest that was
inside a nacelle once, it was uninjured and just
dead, no sign that it was damaged at all.
There is all kinds of misleading stuff like
those links out there, its just not accurate and done by the anti wind folks.
Hope this helps,
Bob Ellison

Subject: [RE-wrenches] Wind Turbines killing birds and bats
Hello Wrenches,
A very knowledgeable friend has concern about
wind turbines killing birds and bats, and sent
me these links. From previous posts on this
list and information I've heard elsewhere, I
thought this really wasn't much of an issue,
more of a red herring by those who are opposed to wind energy.

How much of an issue is this really? Can we put
the danger into perspective? Does this kill
more bats and birds than the pollution it displaces?
Thanks,
Drake
