Bird death toll from turbines

SIR, – Wind turbines kill thousands of bats and Jeff Rogers defends them by quoting from a study (Letters, July 14). Well, the same study says of their search method to count dead bats “some dead bats will have already been removed by scavengers and some carcasses will have fallen into areas outside the search zone”.

So, death counts are an underestimate.

He quotes from another study which compares bird deaths from wind turbines with deaths from other energy sources in 2009.

This is ludicrous because in 2009 there were 75,000 turbines compared with more than 310,000 today.

Finally, he compares the bird death count with those killed by other causes like vehicles and cats. I’m sure that he’s well aware that cats and vehicles normally kill common species like tits and pigeons, whereas turbines kill threatened species like eagles.
