Colorado's National Renewable Energy Lab is working on a project aimed at reducing the number of bird deaths by wind turbines.
The Denver Post reports that the laboratory in Golden is working with radar developer Laufer Wind to test a technology that shuts down the turbines once a bird is detected nearby.
The researchers are using a real-time identification system that can determine what an airborne object is and allows the turbines to be deactivated before they come in to contact with a bird.
To test the system, researchers equipped golden eagles with GPS devices and collected data from several flight tests in February.
Lab researcher Jason Roadman says the results will help determine whether the systems can be implemented at wind farms across the state.
