I thought this article was about something else.
Anne Bonney wondered why utility companies didn't put some sort of flashing light warning or dayglow paint strip or screamer on the giant windmills of avian death. I don't know. Why don't the biggest bird predators try to limit the carnage by giving the birds some sort of warning of impending doom?
Admittedly, I led with a joke. If you're a bird and you can't see what you've flying into, you should probably walk.
