  It hasn’t got anything to do with brain but with vision, we make these things light grey so they blend with the white sky. Just like birds have trouble seeing glass, another thing we made to be as invisible as possible.

    Birds can see more colors than us, at least the majority of them, we have 3 types of photoreceptor: red, green and blue, but the also have a 4th one that allow to see ultraviolet light; that means that bird see a wider range of colors than humans so i strongly doubt that they can’t distinguish between the light grey and white

      The sky is never pure white, and i’m not saying all birds will fly into them if the sky and the windmill are a perfect match. But at the same time, if it were a bright colour less birds would fly into it. Collisions will still happen. It also has to do with the blades rotating, but also that is easier to calculate when the blades are very visible. Still the best thing is to do turn them off sometimes. Best case scenario would be that you can switch over to a source that is also renewable.

        It will still kill less birds than coal and oil, and again they will still distinguish it even if it’s the ssme color of the sky, very few birds will collide with it;
