See, what did I tell ya! LOL
I was thinking more like this stuff.
The guage doesn’t have to be all that heavy, and a basic two by four inch or smaller mesh would probably save a lot of birds.
Seems like a framework could be added to a blade system to stop birds just before they fly into the blades. The blade changes with wind direction, and the wire mesh shield moves with it.
