well it's your lucky day then :)
The Almighty Beev has answered it down there, sort of.
Just to add: the wires are at 240v. the birds are touching the wires (but nothing else) therefore also at 240v. there is no potential difference between the 2, both are at 240v. If the birdy touches the ground (which is at 0v) at the same time then the birdy would be completing a circuit between the wire (at 240v) and earth (at 0v). Potential difference of 240v, therefore current will flow. Birdy bbq.
