|Notice the significant amount of "stand-by" focal points - also known as solar flux - appearing as a white pocket adjacent to each of the three power towers. This super-heated air has scorched and incinerated many birds.|
Many of the birds were killed after being burned by the super-heated air above the project site, while others likely collided with one of the thousands of giant mirrors used to project the sun's rays toward the three power towers. The super-heated air created by the mirrors is often visible from the nearby desert when the mirrors are on "stand-by." When on stand-by, the mirrors focus the sun's energy in the air adjacent to the power tower, rather than focusing the light directly on the tower. The result is a large pocket of air known as solar flux that appears as white mist to the observer (see photos above and below). The Fish and Wildlife Service is concerned that the project's solar flux may also be attracting and killing a significant amount of insects, and they are investigating whether the higher concentration of insects may be attracting more birds to the project site, according to KCET ReWire.
