Rollins Wind: Turbine lights on Rocky Dundee seen from Upper Pond (Rainer Egle)
Thousands of bats are killed by wind turbines every year because they are drawn to red warning light
The mystery of why more than 80,000 bats are killed by wind turbines in the UK each year may finally have been solved.
Scientists found the winged creatures are naturally drawn to sources of red light – an attraction that can confuse them on migration routes.
Turbines use blinking red lights to ward off low-flying aircrafts at night.
Experts now believe this light source lures bats into the path of the blades, which spin at speeds of up to 170mph (275 kph).
According to the latest findings, switching to ‘on-demand’ lighting that only turns on when a plane approaches could cut the number of bats killed by turbines each year.
