An international team of 21 researchers and ecological consultants, including the Museum für Naturkunde Berlin, published a study on the protection of bats at wind turbines in the journal Mammal Review. Against the background of an extensive data set, the authors argue that acoustic recordings can reliably predict the number of bats killed by wind turbines This can then be used to derive the extent of the adjustments to turbine operation necessary to protect the bats. However, a prerequisite for a reliable collision risk assessment is a standardised survey whose results can be compared and referenced with other datasets.
