Bird Vaporization at Ivanpah: Solar Enters Wind Territory

By <a class="post-author" href="/about#w_lusvardi">Wayne Lusvardi</a> -- May 7, 2014

“After several studies, the conclusion for why birds are drawn to the searing beams of the solar field goes like this: Insects are attracted to the bright light of the reflecting mirrors, much as moths are lured to a porch light. Small birds — insect eaters such as finches, swallows and warblers — go after the bugs. In turn, predators such as hawks and falcons pursue the smaller birds.

But once the birds enter the focal field of the mirrors, called the “solar flux,” injury or death can occur in a few seconds. The reflected light from the mirrors is 800 to 1,000 degrees Fahrenheit. Either the birds are incinerated in flight; their feathers are singed, causing them to fall to their deaths; or they are too injured to fly and are killed on the ground by predators, according to a report by the National Fish and Wildlife Forensics Laboratory.”
