This is How a Wind Turbine Takes out a Vulture
This vulture was caught on video by two paragliding pilots who happened to be there when it happened. They captured it and transported it to a wildlife hospital. The bird survived and "every effort is being made to help the two year old vulture recover and to be released again one day in its natural habitat, but the outcome is more than uncertain."
