Wind turbines are often criticized for posing a significant risk to surrounding bird life. As certain numbers indicate, this argument has some merit. A 2001 study estimated that 33,000 birds are killed in the United States each year by wind turbines. More troubling is the fact that of those 33,000, an estimated 28,500 are protected species. Birds may collide with the structure itself, be struck by a spinning blade, or, if flying close enough, be pulled into the turbine’s wake. Though these numbers seem troublesome at first glance, they are an inaccurate depiction of modern wind turbine sites nor do they constitute a valid reason to discourage wind turbine construction.
