Birds can safely sit on electric wires because they do not provide a path for electricity to flow through their bodies. The electricity flows through the wires and does not pass through the birds unless they touch another object that is grounded.
no they dont
For a start, most telephone wires are insulated and carry little or no electricity so, apart from falling off and hurting themselves, they won't get hurt on telephone wires. Really, you should have asked about why birds don't get hurt on overhead electrical wires. The answer is fairly simple really - to get electrocuted from those wires you need to complete the circuit, in this case touch the ground, for the electricity to surge through the body. Birds only sit on the wire and do not touch the ground, so they can't be electrocuted.
Animals can sit on HIGH VOLTAGE Electrical lines. It does not give any current to animals or birds unless the circuit is complete. It is essentlal to complete the electrical circuits for making any current. When bird sit on the line / conductor the only legs of birds touched single line and it does not touch the other two conductors below upper line/conducotr , which does not make circiuit complete and birds / animals does not feel current.
High voltage electricity can kill if it passes trough your body. When birds sit on the power cable, the electrical current cannot pass trough their body because no part of their body is touching the ground or any other wire.
The wingspan on a big bird is large enough to touch two wires at once. Any difference in voltage between the wires will cause current to flow through the bird, perhaps killing it. Small birds can only touch one wire at a time.
birds have special tendons that allow them lock around the perch. With tendons located behind their ankle and in front of their knee, they weight of their body stretches the tendons so they lock around the perch
Birds sit on a nest.

Birds fall from the window ledge above mine, flapping their wings at the last second towards a horizontal flight. Due to a construct in my mind it makes their falling and their flight symbolic of my entire existence. If you want to electrocute birds, all you need is a bug zapper, hence the name.
Birds sit on a nest. It begins with the letter n.
tripping over lose wires or cables spilling drinks on electrical equipment (talking from experience here!!) muscle or skeletal problems if you don't sit correctly
