A note from sloetoe@yahoo.com:

Regarding wind turbines and wildlife (avian) impact, the results of this study suggest "no big deal" however, with regard to an unexpectedly high bat mortality, the observation is "Holy Cow!"

Seems pretty silly to me. (The uncertainty mentioned regarding why bats were so much more susceptable than birds.) You take a echo-locator, put it in a noisy environment (a ridge top windy enough for a turbine site), then flood the area with low frequency throbbings overlain with 60 Hertz/harmonics noise, and then put your finger to your cheek and exclaim "Gee! Isn't that strange!"

I'll bet you that there's already an equation on the internet for sizing cuts into the trailing edges of the wind turbine to produce a sound frequency that would act as an irritant/warning to flying rodents in the area. 

Just a thought....
