[RE-wrenches] Wind Turbines killing birds and bats

[Drake]

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
