California solar power plants singeing bird feathers
IN THE MOJAVE DESERT, Calif. — The picture is unsettling and disturbing.
A small bird, barely the size of a human hand, had its wings reduced to a web of charred spines. No longer able to keep aloft, the bird was found on the ground after it had flown through the intense heat of a solar thermal project soon to go online in the California desert.
The photograph, taken at BrightSource Energy's Ivanpah plant in east San Bernardino County, has raised the stakes for a similar project in Riverside County. Months from final state and federal approvals, the Palen solar thermal power system could put two 750-foot-tall solar towers and thousands of reflecting mirrors near two of the region's key wildlife refuges and stopping points for birds migrating along the Pacific Flyway.
The project is roughly 50 miles from both the Salton Sea to the southwest and the Cibola National Wildlife Refuge in Arizona to the southeast.
"A migrating bird has to be in top form, having the flight feathers in really good shape," said ornithology collections manager Kimball L. Garrett of the Museum of Natural History of Los Angeles County, who has not seen the picture from Ivanpah but has been concerned about bird deaths at large solar projects.
"If some of its flight feathers are damaged, what does that mean for the rest of the bird's migration?" he said. "It weakens feathers. These are things people don't study because — how can you?"
