Efforts to mitigate bird mortality at wind farms have focused on both visual modifications and technological innovations. A 13-year study at the El Ruedo wind farm near the Strait of Gibraltar demonstrated that painting a single rotor blade black can significantly reduce bird fatalities. The research found a 74 percent reduction in mortality at turbines with black blades, dropping from an average of 1.11 dead birds per turbine per year to 0.29. The study also noted a decrease in mortality at adjacent, unpainted turbines.

Complementing visual deterrents, new vertical axis wind turbine technology has been developed to protect avian populations. This system utilizes radar and AI-driven image processing to detect approaching flocks, allowing the rotors to slow or stop within seconds. Additionally, these turbines incorporate biomimetic blade designs that mimic bird wings to optimize energy capture while minimizing turbulence.
