Even though bird conservationists cite an increase in bird mortality as a result of wind turbines, most of the existing research shows that wind turbines kill fewer birds than other man-made structures and comprise only about one-tenth of 1 percent of all ''unnatural'' bird deaths in the United States each year. According to the American Wind Energy Association, natural causes -- such as baby birds falling off nests -- account for 30 percent of bird deaths. Power lines, windows, pesticides, automobiles, communication towers and domestic cats cause more unnatural bird deaths than wind turbines. The national estimate for turbine-related bird deaths from the 25,000 operating turbines is 10,000 to 40,000 per year, while 1 billion birds die each year from flying into windows.
