In an article published in The Guardian on November 7th, the RSPB (Royal Society for the Protection of Birds) is quoted saying that since 1980, across 25 European countries, house sparrow numbers have declined by 147 million, a 62{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} drop to 90 million. According to the same report, starlings have fallen by 45 million, down to 40 million. As for Skylarks, their population went down by 37 million, to 43 million today. Says the author of the article, “It’s principally agricultural intensification that is behind the crisis.” (1)
Populations ranging from 40 to 90 million birds, for the most common of passerine species, are surprisingly small, spread as they are over 25 countries. Thus, if the researchers quoted by the RSPB are correct in their estimates, we are entitled to conclude that wind turbines and their power lines will have a significant impact on the number of all passerines flying our skies, eating our insects etc. Indeed, we know for instance that, in Spain alone, wind turbines kill 6 to 18 million birds and bats a year (2). Supposing that Europe has about 5 times as many wind turbines as Spain, the death toll for Europe would be 30 to 90 million birds and bats per annum – i.e. roughly 10 to 30 million birds a year, given that bats are attracted to wind turbines and killed about twice as often as birds. Comparing the numbers, and all things being equal, it is obvious that bird populations will erode further on account of wind farms, much faster than previously thought.
But no mention is made of this in the article. It’s not surprising, as both the RSPB and The Guardian are promoting the installation of ever more wind farms across Europe.
