A bird can safely land on a bare, high-voltage power line because



▸

if both feet are touching the bare wire, they are at approximately the same potential, and therefore little or no current flows through the bird’s body.



▸

its internal resistance is very high, so very little current will flow.



▸

the line cannot deliver enough current to harm it.



▸

its feet are good insulators, and therefore it is protected.
