Briefings

A long-term study by Mongabay and researchers at Acciona Energía in Cadiz, Spain, found that painting one blade of a wind turbine black dramatically reduced bird fatalities. Between 2012 and 2024, the painted turbine at El Ruedo farm saw a 74% drop in annual bird deaths compared to uncolored controls, while other studies in Norway and South Africa reported similar reductions. The experiment involved painting one of three blades black on four turbines, with daily monitoring of dead birds. The study concludes that color disruption can significantly mitigate bird collisions, though the specific mechanism remains partially understood.

Key points

• A long-term study by Mongabay and researchers at Acciona Energía in Cadiz, Spain, found that painting one blade of a wind turbine black dramatically reduced bird fatalities.
• Between 2012 and 2024, the painted turbine at El Ruedo farm saw a 74% drop in annual bird deaths compared to uncolored controls, while other studies in Norway and South Africa reported similar reductions.

Context and limitations

The study covers only one turbine at El Ruedo farm in Spain, and data collection began in 2012. Results are based on bird fatality records rather than direct collision measurements. The study does not account for other environmental factors or long-term ecological impacts beyond immediate collision rates.
