Hi Suzanne,

I read the full scientific publication and found it strange that it only discusses diurnal birds. The majority of bird collisions in Nova Scotia involve nocturnal migrants, and I’m not sure the black blade would have the same effect at night. Also, the wind turbines they studied are relatively short compared to the taller wind turbines that are now being constructed and reach further into the altitude in which migratory birds are flying.

I don’t understand why the paper does not discuss nocturnal conditions. I could not find the words nocturnal and night in the article.

Bird deaths down 70 percent after painting one blade on each wind turbine black.
