"The sight of small birds perching on electric wires is something that commonly occurs. Birds often do this because electric wires have a structure similar to the places where birds usually perch naturally and are difficult for predators to reach. However, have you ever wondered why these birds do not experience electric shocks when they perch on those high-voltage wires?"

"However, this scenario only occurs when both feet of the bird occupy the same wire, without any other part of the body touching objects other than the wire it is perched on. If the bird accidentally stretches its wings to touch another wire or perches on two power lines with different voltages simultaneously, electric current will flow through the bird's body and cause an electric shock."
