Abstract
Bird collisions in wind turbines are a fact and will be on the rise with the increase in the number of wind farms around the world. Existing bird control tools like radar, HD camera or human visual detections have a number of drawbacks each and have not been able to prove their efficiency up to the standards of wildlife protection national organizations and supranational groups. Precision and range of thermal imaging combined with appropriate software provide for likely the most reliable bird and bat detection capability today. Detection recordings present a way of objectively analyzing the performance and accuracy, while custom-designed sounds invoking acoustic startle reflex deter virtually all avian species already at 400+ meters without allowing for habituation and minimizing the need for WTG stoppage, thus maximizing wind farms’ production efficiency.
