Bird death from wind turbines is a popular topic amongst the anti-wind
lobby, along with wind turbine syndrome. (For a quick survey of wind
turbine syndrome, visit http://skeptoid.com/episodes/4388)
Here's a relevant snippet regard avian death from wind turbines.
"Several studies have compared the effect of different energy sources on
bird mortality overall. One, published earlier this year ,
calculates windfarms killed 20,000 birds died in 2009 in the US - while
nuclear plants killed about 330,000 and fossil fueled power plants more
than 14 million. The research concludes that taken together,
fossil-fueled facilities are about 17 times more dangerous per gigawatt
hour of electricity produced to birds than wind and nuclear power stations."
Domestic and feral cats still appear to be the number one bird killers,
followed by bird strikes into buildings, power lines, vehicles,
communications towers, etc. It takes a while to get down the list to
wind turbines, which appear to come in far behind bird deaths due to
There are a couple of early windfarms which had a high impact on bird
mortality. The industry learned from those and have implemented changes
to siting, design, site set-up and operating regimes to reduce their
impact on birds. I think that is laudable and worthy activity.
However, if the real issue is the rate of bird death, attacks on wind
turbines need to be taken in the context of other causes of bird death.
Is there substantial support for culling the cat population, as it is
the single largest cause of bird death?
There are a lot of headline-seeking articles regarding wind turbines and
bird deaths, but a balanced review of the evidence available shows it is
not as big an issue as the headlines would suggest, especially in the
context of other causes of bird deaths.
