An excerpt from a post by John Fund at National Review:
Then there is the carnage inflicted on Mother Nature. Paul Driessen reported in the Washington Times that “the U.S. Fish and Wildlife Service estimates that wind turbines kill 440,000 bald and golden eagles, hawks, falcons, owls, cranes, egrets, geese, and other birds every year in the U.S., along with countless insect-eating bats.” The actual numbers are probably far higher. The turbine blades of the nation’s 39,000 windmills move at 100 to 200 miles per hour and can mow down anything that gets in their path.
Over the past 25 years, an estimated 2,300 golden eagles have been killed by turbines at Altamont Pass, Calif., alone, leading to an 80 percent drop in the golden-eagle population of southern California.
