Why Don't Birds Get [ Electrocuted ] on Electric Wires?

You look up on a bright sunny day to see a line of tiny birds on power lines looking down at you.
How is it they can stand on an electric wire and not receive an electric shock? It's a good question since you know that if you were to touch that wire yourself, you'd likely receive a dangerous shock of electricity.
What are the reasons why birds are not electrocuted when they're in direct contact with an electric wire?
