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.

I hope I did not spread fake news. I do not know the authors.
Apologies,

No, I’m glad you posted it and brought attention to these findings. I just wonder why
there was no discussion of nocturnal migrants.
