The reason for this has to do with the fact that electrical current, which is a flow of electrons, generally flows along a path of least resistance. The electrons want to get to where they are going in the easiest possible way, much like a person might walk on the sidewalk instead of the grass because it is easier. When a bird sits on a wire and the electrons reach the part of the wire where the bird is sitting, the electrons have two options. They could go through the bird's feet and encounter a large amount of resistance or they could go through the wire. All wire are good conductors, which means that electrons flow through them easily. Because it is easier to travel through the wire instead, the electrons don't go through the birds feet, so the bird stays safe.

because you need both negative nad positive to get a shock , birds just stand on one line and therefore the current never flows hence no shock

The birds are not touching the ground or anything else for the current to be running through them.

Since they are preched on a single wire the circuit is not complete and the do not get a shock

because u cant get shocked by touching the wires...its like touchin a cord in your house...there not open livewires that can shock you upon touch they are insulated rubber wires containing charged circuits

To be shocked you have to touch both lines.

They're not completing a circuit, so there's nowhere for the current to go.

Because the current is not being earthed.
