A study by the Leibniz Association provides the first evidence that male bats sing courtship songs within the rotor-swept zones of wind turbines, increasing their risk of fatal collisions. Using over 80,000 audio recordings and 3D thermal tracking at six sites in Germany, researchers found that bats actively circle turbine nacelles while singing, rather than merely passing by. Wind turbines may act as attractive “song perches” in otherwise featureless landscapes, drawing both males and females during mating season.
Notably, species such as the common noctule and Nathusius’ pipistrelle, which are most frequently killed by turbines, were also the most commonly recorded singers. Their calls can attract females, potentially explaining higher female fatalities. The findings suggest bats deliberately approach turbines for mating purposes, not just feeding or roosting. Researchers hope this insight will help develop targeted mitigation strategies that balance renewable energy development with bat conservation.
