March 6, 2013 (San Diego) -- According to a recent "Golden Eagle Threat Alert" by the Wildlife Research Institute (WRI), “human activity is causing the rapid extirpation of our last remaining Golden Eagle Territories.” They claim that over the past few decades, the number of San Diego’s “active golden eagle territories” has dropped from 103 to 49.

The US Fish & Wildlife Service states that wind turbines kill almost half a million birds every year. More recent studies suggest the number is much higher, somewhere between 13 and 39 million birds. Many of these are raptors.
