The Trouble with Turbines

When the biologists weren’t looking up at the sky, they were scouring the ground for carcasses of griffon vultures (Gyps fulvus), Spanish imperial eagles (Aquila adalberti) and other species. The Spanish Ornithological Society in Madrid estimates that Spain’s 18,000 wind turbines may be killing 6 million to 18 million birds and bats annually. “A blade will cut a griffon vulture in half,” says Bechard. “I’ve seen them just decapitated.”

Wind turbines kill far fewer birds in general each year than do many other causes linked to humans, including domestic cats and collisions with glass windows. But wind power has a disproportionate effect on certain species that are already struggling for survival, such as the precarious US population of golden eagles (Aquila chrysaetos canadensis).
