"Painting one of a wind turbine's three blades black led to a dramatic decline in bird mortality along the Norwegian coast, new research shows.

Bird death from turbine collisions dropped by 71.9% where a turbine blade was black, compared with unpainted turbines at the same wind farm, according to findings published last month in the peer-reviewed journal Ecology and Evolution.

Researchers observed a nearly 50% reduction in mortality from collisions involving towers with a single black blade."
