Former President Donald Trump recently claimed that wind turbines are responsible for a significant number of bird deaths, describing the areas beneath them as “bird cemeteries” with “thousands of birds dead” beneath them. While his assertion highlights a real issue, the broader context reveals a more nuanced picture.
Wind turbines do indeed pose a threat to birds. Research conducted by specialists at the American Bird Conservancy estimates that wind turbines are responsible for nearly 1.2 million bird deaths annually in the United States. Some of the affected species include vulnerable avian populations such as golden eagles, bald eagles, burrowing owls and peregrine falcons.
However, while the number of bird deaths caused by wind turbines is concerning, it is relatively small compared to other causes of avian mortality. Cars, pesticides, buildings and the fossil fuel industry collectively contribute to hundreds of millions of bird deaths each year. Even household cats are estimated to kill as many as one billion birds annually in the U.S. alone.
Overall, wind turbine-related bird deaths represent less than 1% of the total U.S. bird population each year. Although some of Trump’s claim is factually accurate, the impact of wind turbines on bird mortality is statistically minor when compared to other human-related threats.
