Why don't birds get electrocuted when they perch on power lines?

According to Ohm's Law, the current flow through a circuit is proportional to the potential difference, also called voltage or voltage. In the present case, the bird is the circuit. The potential difference between its legs is very small, so only a tiny fraction of current passes from the wire to the bird's body . Now, if the animal also touched a second wire, a large voltage would be created between it and the ground, and it would be instantly electrocuted.
