By David Gardner Last updated at 11:11 PM on 6th June 2011 California's attempts to switch to green energy have inadvertently put the survival of the state’s golden eagles at risk. Scores of the protected birds have been dying each year after colliding with the blades of about 5,000 wind turbines. Now the drive for renewable power sources, such as wind and the sun, being promoted by President Obama and state Governor Jerry Brown has raised fears that the number of newborn golden eagles may not be able to keep pace with the number of turbine fatalities. The death count along the ridgelines of the Bay Area’s Altamount Pass Wind Resource Area has averaged 67 a year for three decades. The 200ft high turbines, which have been operating since the 1980s, lie in the heart of the grassy canyons that are home to one of the highest densities of nesting golden eagles in the US. ‘It would take 167 pairs of local nesting golden eagles to produce enough young to compensate for their mortality rate related to wind energy production,’ field biologist Doug Bell, manager of East Bay Regional Park District's wildlife programme, told the Los Angeles Times. ‘We only have 60 pairs,’ he added. Nationwide, about 440,000 birds are said to be accidentally killed at wind farms each year, as well as thousands more bats. With the government pushing for more wind energy farms, that statistic is likely to rise. Another recovering species, the California Condor, is also said to be at risk from the giant blades. ‘We taxpayers have spent millions of dollars saving the California condor from extinction,’ Gary George, spokesman for Audubon California, told the Times. ‘How's the public going to feel about wind energy if a condor hits the turbines?’ Newer carbines are said to be less harmful to birds and the U.S. Fish and Wildlife Service has asked power bosses to turn off the wind machines during times of heavy bird migration. But the moves have done little to protect the golden eagles, which weigh about 14 pounds and stand up to 409 inches tall. Their flight behaviour makes it difficult for them to navigate through masses of wind turbine towers, especially when they are easily distracted by prey on the ground. ‘The eagles usually die of blunt-force trauma injuries,’ said Mr Bell. ‘Once, I discovered a wounded golden eagle hobbling through tall grass, about a quarter mile from the turbine blades that had clipped its flight feathers.’ ‘A wind farm owner once told me that if there were no witnesses, it would be impossible to prove a bird had been killed by a wind turbine blade. My response was this: If you see a golden eagle sliced in half in a wind farm, what other explanation is there?’ he added.

409 is not the height of golden eagles. It is an engine size.
~~~~~~~ well it says 409 inches. Obviously a misprint of some sort. from wiki: "So this is how liberty dies, with thunderous applause." -Padme, Star Wars III, Sith
Maybe when congress stops W.F.I.Z.G. (wars for israeli zionist garbage)we could research a sound,smell,or any type of non-invasive deterrent to ward off all birds,yeah,like that'll happen.

You hit the nail on the head with wind there, farmfriend. When the wind don't blow, the deficit on the grid has to be made up lickety-split, and nothing does it like gas turbines that can be fired up on a moment's notice to send power down the line. You can't run wind power without them. This negates much of the "renewables" advantage touted by the green, green propaganda machine.
It is a violation of Natural Law to use this document in a manner inconsistent with its labeling.
If the birds can't figure out to avoid the turbines maybe they should go the way of the dodo.
Yup. Wind energy will not be effective until we have the ability to store large amounts of energy. Wind energy is on or off as the output varies with the cube of the wind speed. We have a wind turbine on our farm, but we have a battery bank with it. The birds love it. The guy wires are always covered with birds and so far no dead birds at its feet. So we are easy on the birds, but our cats...........

The Golden Eagle is a large, dark brown raptor with broad wings. Its size is variable: it ranges from 70 to 85 centimetres (2 ft 4 in to 2 ft 9 in) in length, has a wingspan of 185 to 220 centimetres (6 ft 1 in to 7 ft 3 in), and weighs 3 to 6 kilograms (7 to 13 lb)
