"…according to the National Research Council, wind turbines account for less than 0.003% of bird deaths caused by human activities. The U.S. Fish and Wildlife service estimates that wind turbines kill 150,000 - 200,000 birds annually. Meanwhile, hundreds of millions of birds are killed every year by collisions with buildings, cars, and power lines. And many more are killed by oilfield production pits and coal mining, which has destroyed numerous bird habitats.
"A 2009 comparison of the impact of six electricity generation types on wildlife in New England found that wind power poses “no population-level risks to birds.” Factoring in the effects of pollution and climate change, it concluded that “non-renewable electricity generation sources, such as coal and oil, pose higher risks to wildlife than renewable electricity generation sources, such as hydro and wind.”…”
