They killed (and continue to kill) astronomical levels of rare and endangered species protected by both Federal and state law but they get a pass.
Truly, some animals are more equal than others.

These astronomical levels of raptor mortality continue unabated, due in part to the failure of federal and state wildlife protection agencies to take any regulatory action. Bird kills at Altamont Pass occur in violation of federal and state wildlife protection laws, including the Bald Eagle and Golden Eagle Protection Act, Migratory Bird Treaty Act, and numerous California Fish and Game Codes.
The wind power industry has been aware of the magnitude of the impacts to birds of prey at Altamont Pass since at least 1988, when the first of numerous studies of raptor mortality was published. To date, the industry has not implemented a single meaningful mitigation measure to reduce raptor kills or to compensate for removing significant numbers of birds from populations of imperiled species.
In fact some efforts, such as the rodent control program at Altamont, have actually increased the risk to raptors while threatening endangered species such as the San Joaquin kit fox, California red-legged frog and California tiger salamander.
Recent research by the California Energy Commission has shown the mortality risk to raptors at Altamont Pass has significantly increased over the past 15 years.
