A bird can sit safely on a wire if it does not touch another wire or the pole at the same time. Touching another wire or the pole will complete the circuit and electrocute the bird.

What usually causes Electrical chock (from AC power lines 220 or 110 volts) is the electrical current ,electrical current needs a complete circuit to flow, therefore the bird will not be affected because its only touches one wire the circuit is not complete.
But in the case of very high tensions (in the order of kilo volts), the voltage itself can harm the birds, (even without touching the wire, just being close enough to these voltages can cause electrical chock).

In contact with water. Probably while the birds are sitting on these wire, they peed hence got electrocuted..

Its because they have each foot on a wire of opposite potential, so a net zero voltage and current.

they have to be touching 2 wires... most bird don't
