Not nearly as much as other things. Causes of Avian death per year:
Collisions with buildings - 550,000,000
Power lines - 130,000,000
Cats - 100,000,000
Cars - 80,000,000
Pesticides - 67,000,000
Communication towers - 4,500,000
Wind turbines - 28,500
Airplanes - 25,000
Numbers for bats not available. Almost no bats are killed by collision - bats generally don't run into things.
However they are killed by the sudden drop in air pressure near the turbine.
I don't doubt we kill them in other ways...
We just have found a new way to do it.
So...green.
