The mechanisms underlying bat and bird activity peaks (attraction) or losses (avoidance) near wind turbines remain unknown. Yet, understanding them would be a major lever to limit the resulting habitat loss fatalities. Given that is strongly related airflows, we hypothesized airflow disturbances generated leeward (downwind) of operating turbines-via so-called wake effect-make this area less favorable for bats, due increased flight costs, decreased maneuverability possibly lower prey abundance. To test hypothesis, quantified Pipistrellus pipistrellus acoustically at 361 site-nights in western France June on longitudinal distance gradient from turbine circular azimuth incidence angle, calculated prevailing direction night. We show P. avoid area, as was detected than windward (upwind) relatively moderate high speeds. Furthermore, found response (attraction avoidance) depended angle area. These findings are consistent with hypothesis changes airflows around can impact way bats use habitats up least 1500 m turbines, thus should prompt consideration winds energy planning. Based evidence present here, recommend avoiding configurations involving installation between origin important such hedgerows, water woodlands.
