One small-scale study in Norway found that painting a single blade black allowed birds to likely see the turbine better and avoid collisions. The reduction was over 70 percent, with raptors like

The annual fatality rate was significantly reduced at the turbines with a painted blade by over 70%, relative to the neighboring control (i.e., unpainted) turbines. The treatment had the largest effect on
Customer Service
Researchers hypothesize that the black-painted blades will disrupt the visual uniformity of the airspace, making the turbines more noticeable to birds and prompting avoidance behavior.
