Because they aren't completing a circuit. There's only so much electricity going through those lines, and the lines are much better conducters than birds are. The electricity just takes the path of least resistance: Through the line. Which leaves the bird perfectly safe.
The problem is when a big bird like a goose flies into some wires and touches either two wires, a wire and the pylon, or a wire and the ground. In those cases it's completing a circuit, and that's when it gets zapped.

Of course a shock need both poles, but a high tension single wire gives shock to man,
Every body, person or a bird works as a small capacitor, as it has big body mass it will posses more capacity. When a man touches the high tension wire, its own capacity allows a little A/C current pass through its finger, hence giving some sensation of shock.

The power plant sends one phase of the Alternating Current through the power lines, and the opposite phase into the Ground.
In order to partake in the conduction of that electricity, you must be part of the path the electricity takes in order to get from the power lines to the ground.
If you are simply touching the ground, or simply touching the power lines, but are in no way making it easier for electricity to go from the one to the other, you are not part of the circuit, and no electricity will course through your body.
For example, take a 9 volt battery. Wire it to a flashlight bulb so that the flashlight bulb glows, and there is electricity flowing in the circuit. Now take a voltmeter and touch both terminals to a wire. Even the there is electicity flowing through the wire, the voltmeter does not help (only minutely) electricity flow through the circuit, and therefore no voltage will register.
Only when you help electricity circumvent a resistor or otherwise help complete a circuit will you get zapped.

simply, when bird sits on high tension line, it touch either negative or positive line. it can't get shocked without touching the two lines at the same time as the circuit be connected.

birds go through no electric powered shocks because of the fact they might not get earthed. whilst they are not earthed, electricity can not bypass via their physique to the floor, for this reason they at the instant are not getting a marvel.Small birds at the instant are not so great to make a sprint with the two the valuable & impartial lines.So there is not any question of being earthed.( although, great sufficient birds might get it achieved & they get the marvel. familiar electricity (220 V) isn't so efficient to create a discharge via air. even though it extremely is not interior the case of severe-stress lines (one thousand V or greater). you will detect a chook electrified in the event that they take a seat on those lines. thousands of crows die because of this reason. you additionally could have help for my opinion,in case you have repaired electric powered issues. this is often recommended to placed on a pair of dry sandals together as engaged on. here the dry sandal works because of the fact the insulator & prevents passage of modern-day via your physique to the earth. although in case of severe stress lines greater solid insulators are for use.a pair of moist sandals won't do on account that moist rubber is a properly sufficient conductor of electricity so which you will get a marvel. A chook sitting on a potential line, gets a marvel if the present during the cord be extremely solid besides because of the fact the day be very humid. if so the moisture modern-day in air makes the air a solid conductor of electricity,which permits electric powered discharge via air ensuing interior the chook to get a marvel.

Because they're waring sneakers (the electrical lines are INSULATED and only a danger when stripped or the metal wires inside are otherwise exposed, as in from a break, etc). Just look at the cord on your computers AC plug. Same thing.

Because they are only on one side of the alternating current. Sometimes a big bird will get electrocuted if their wings touch the other wire.

You won't either unless you touch an exposed cable/wire. Tension lines/electric lines have a cover shield over the wire.

To get a shck you have to touch both wires. For humans the ground is another wire
