When one thinks of bird killers, predators like cats probably come to mind. But it appears there’s another scourge to our feathery friends and it comes in the form of wind turbines. Yes, those same turbines that are supposed to be earth friendly are, according to the American Bird Conservancy, decimating tens of thousands of birds each year in their spinning blades. Fortunately, there’s a new technology being tested in Alaska that uses blades which are spun vertically, not horizontally, and are easier for birds to detect. If successful, this new contraption, which looks like a couple of 55 gallon drums on a spinning pole, will head off an emerging ecological tragedy, which experts say could claim over 1 million birds by 2018.
