I think I'd have to see that for myself to believe it. Sorry. Those wires are kept several feet apart. That's a long snake for a bird to haul up and dangle down (5+ feet I would imagine).
I'm not saying it's impossible. But for it to be so common that the power company had an explanation? I'm trying to buy it. :o)
This is an old rural line back to a residence. I don’t think the wires are more than two feet apart.
