Group sounds alarm over wind energy threat to birds

National Bird Conservancy says wind energy must be properly planned so bird populations are not affected.  According to their website:  Wind power has the ability to be a green, bird-friendly form of power generation, but can also adversely affect birds. Birds can die in collisions with the turbine blades (up to 14 birds per megawatt per year in the U.S., with a median rate of around 2.2 birds/MW/Yr according to industry estimates), towers, power lines, or related structures, and can also be impacted through habitat destruction from the siting of turbines, power lines, and access roads. Some birds, such as sage-grouse are particularly sensitive to the presence of turbines, and can be scared away from their breeding grounds several miles away from a wind farm.
