Acoustic lighthouse deflects birds from wind turbines

high pitched noise deflects bird

Wind turbines kill around 350,000 birds per year. According to Popular Mechanics, “when birds fly, they’re usually looking down at the ground instead of ahead of them. This helps with navigation, but increasingly poses a problem when very tall objects like buildings or turbines are placed in front of them … A group of scientists at the College of William & Mary have come up with a solution: an ‘acoustic lighthouse’ that can drive birds away from turbines before it’s too late.”
