I feel sorry for the birds in that area.
Although enviros claim an ESTIMATED number of birds are killed annually, they have no EMPIRICAL data to prove their claims. Yes, birds are killed, but I don’t believe it comes anywhere near the numbers they’re claiming or there would be mountains of bird carcasses at the base of every turbine.
So, they’re charging full speed ahead to get these wind farms shut down. Even the Sierra Club cannot provide any EMPIRICAL data, they persist in using the term ESTIMATE.
These blades don’t move at the speed of a household fan, they’re rather slow and if a bird can avoid a car moving at 60-70 mph, why can’t they avoid a fan blade moving at 16-20 rpm?
Cats might kill an ESTIMATED 100’s of millions of birds each year, shall we ban cats? See how easy it is to make an unqualifed assumption based solely on the FACT that we do KNOW for CERTAIN that cats kill birds?
Page 6 of the following pdf discusses wind turbine fatalities and the faulty methods and “assumptions” environemntalists are using to “bump up” the numbers at Altamont Pass and other wind turbine locations.
