Background information and definitions
It has been suggested that bats may misidentify the smooth surfaces of wind turbine towers as water (e.g. McAlexander 2013) and applying a textured coating could reduce bat collisions and fatalities. Behavioural experiments in flight rooms found that bats did not make contact with textured surfaces and approached them less often than smooth surfaces (Greif & Siemers 2010, Bienz 2015). However, this has not been tested on operational wind turbines.
