A wind turbine farm owned by PacifiCorp stands near Glenrock, Wyo., Monday, May 6, 2013. Wind farms owned by the company, with clusters of turbines as tall as 30-story buildings and spinning rotors the size of jetliners, have killed at least 20 eagles in the state, according to data obtained by The Associated Press.
