Can you imagine a large flock of birds traveling through a windmill farm? Avoiding two types of collisions at the same time might overpower their abilities. Someone should arrange it so that the windmills are along the migration roots of starlings.

I think there was a problem with small, rapidly spinning, first generation wind turbines in the 1970s. - Jed
