Question

Why do birds fly away when a high voltage wire?

Answer 1

Electricity flows by the movement of electrons through conductors. ... A body is a poor conductor compared to copper wire, so no electricity flows through the bird. There's no voltagedifference in a single wire. Electricity flows from areas of high voltage to areas of low voltage.

Answer 2

When the current is switched on, induced current flows through the body of the bird. The induced current flows in the opposite direction through the wings of the bird.
Hence the wings experience a force of mutual repulsion. The wings spread and hence the bird flies
