Bird attrition is a subject that I have previously referred to and it would seem if we listen to Renewables UK, Scottish Renewables, the DECC and the Scottish Ministers that British Birds are more intelligent or more adept at evasion than their US or Spanish equivalents. In fact even their euro cousins in Germany seem to be bumping into turbines more?
So who is telling the truth, or are the wind industry literally burying the birds? Certainly anecdotal evidence suggest that bird and bat numbers decline in the vicinity of a wind farm after construction and wind farm operators have referred to an increasing number of immature raptors populating wind farms. The most likely cause for that is that the parents have been killed. Another issue is the poisoning of raptors on estates prior to wind farm applications which result in bird surveys showing no conflicts. Again these may be isolated cases but those are the ones discovered. On one local estate they had a “clay shoot” on the sunday that sounded like down town Beirut when on the Monday the birdie people came to do the survey. Not surprisingly the survey showed little bird activity.
