Why don't birds get electrocuted when they land on an electric wire?

Because both of the bird’s feet are on the wire no electricity flows through it. There is no circuit, its two feet are at the same electric potential, and electricity travels along the wire instead of through the bird, so the bird doesn’t get shocked.   https://www.studyhelpus.com/why-dont-birds-get-electrocuted-when-they-land-on-an-electric-wire/
