They sit on the insulation. They do get shocked on bare wires.

For 2 reasons. 1. the bird is not grounded. This means that the bird is not touching anything that the current could pass from the line, through the bird to the ground object which is contacting the ground in some way. 2. The wires have a protective casing that keep the bird from touching the wire itself, so it may not even get shocked if grounded.

Do you mean to ask how can a bird sit on a high-voltage wire without being shocked?
If so....the answer is because there is no difference of potential. (between the birds feet)
In order for the bird to be shocked, it would have to have each foot on a different wire...each wire would have to have a different voltage.
Since both feet are on the same wire, and no other part of the bird is in contact with anything else(like the ground), there is no difference of potential, therefore, the bird is not shocked.
If you or I grabbed the same wire, and no other part of our body was in contact with the ground, or the power pole, or a ladder...anything, then we too would not be shocked. If we grabbed the wire and we were to touch something such as the ground then we would be shocked...because there would be a difference of potential. the wire would be a certain voltage, and the ground would be a value of zero voltage...a difference, understand?

Ummmm...if by "Hydro" you mean water, it does not shock anything(bird,man,etc.). If you live in some jacked-up country where they call their electrical lines and wires hydro, and birds are "sitting" on them, you need to move. Here in America our birds "stand" on our power lines using and are not shocked because they do not complete an electrical circut.

anything can sit on a hydro line and not get shocked as long as they are not grounded to anything. You ever see a squirrel run along a hydro line, I have and it is really neat to see them do that, then when they get close to the pole they jump onto the pole so they don't get shocked either.

Most of these answers are correct, the birds are only sitting on one wire and not making a complete circuit. But what they aren't saying is that a lot of birds of prey are killed each year when they touch more than one wire. Here's a link with a good explanation.

Because all the electricity wants to do is stop and the only way to do that is if it reaches the ground. It cant get to the ground through the birds because the bird sits up and even if it was hanging upside down it wouldnt get a shock. the bird would have to be touching the ground and the wire to recieve a shock.

Russ S is correct. You cannot get shocked unless current can pass through you to ground, and when a bird lands on a wire there is no path to ground through the bird for current to pass along.

They are on one wire either the live one as they say or the ground. They have to have both to get shocked. Even bare wire if they are not grounded. When they come into contact with both then fried bird.

u actualy know the answer to this question ....but heck u figuered to ask anyway to see what results u get ..huh? well birds don't get shocked beacose they keep both feet on the same line ....and ...i guess they do have some kind of isolation ...( it is a more Phisical expalnation but i don't know ) if u really don't know search wiki
