English summary by Mark Duchamp:
A five-year monitoring report of 8 wind turbines near the coast in Vendée, France, by the French ornithological society LPO (Ligue pour la Protection des Oiseaux), discloses the following:
bird mortality: 5.7 to 33.8 per turbine/year, depending upon the year and the estimation method. It is estimated that 20% were migrating birds.
bat mortality: 6.0 to 26.7 per turbine/year, depending upon the year and the estimation method. It is thought that many of them were migrating. The bats showed no external injury. But the autopsies revealed that their internal organs had been destroyed, possibly as a result of high air pressure created by the blades. This is what we learn from the abstract and from an enclosing email from FED, which reports the words of a researcher 4 years ago at an ornithology meeting in the region (body imploded, internal organs destroyed):
“Il y a 4 ans, un chercheur aux journées internationales de l’avifaune à Menigoute dans les Deux Sevres avait dit: ‘lorsque l’on dissèquent ces cadavres, on dirait qu’ils ont implosés, l’aspect exterieur est intact et ce sont les organes internes qui ont été détruits’.”
