OtaGamer Says: The reason that birds don't get hurt on power lines is because they put both of their feet on the wire at the exact same time. Therefore, the electricity passes through one leg and up out of the other. If they lifted up one of their legs, they would be electrocuted and die.
Birds do not get electrocuted when sitting on power lines because they are not completing a circuit for electricity to flow through. The electricity in power lines travels in a closed loop, and birds are not grounded so there is no path for the electricity to flow through them. Additionally, most power lines are insulated to prevent electricity from leaking out.
Birds perching on power lines do not get electrocuted because they are not completing a circuit by touching another conductor. The power lines are insulated and the birds' legs are not close enough together to create a path for electricity to flow through their bodies.
That is to warn birds so that large flock of birds do not fly into the power lines. Also helicopters.
The answer is yes they can touch one another when there on power lines
Usually they don't.
Actually if we were to sit on a power line and not touch anything else like the birds do we would not get electrocuted.The current a flow of electrons,flows along a path of least resistance the electrons want to get to where they are going in the easiest possible way. Electricity flows from one voltage to another value of voltage. For the birds, the power lines have the same voltage -- so the birds are safe. Don't approach power lines, because humans come from the ground, which is a sink for the current.

Smaller birds can fly through the gaps in power lines and bigger birds get stuck when they try to go through.
Because birds are not 'grounded'. This means they are NOT touching the power line AND the ground, at the SAME time.
The power lines are buzzing because of the electromagnetic fields created by the electricity flowing through them.
I took coils of roofing nails and uncoiled them to make a strand of nails and zip tied them,point up, to my cable and phone lines that are overhead. But would not recommend this for your homes overhead 240/120v electric line. IMO
because the lightning hits the the power lines and electricity runs through power lines
