The ID parade

"Squawk! Hey - why are we here?"

"Someone had their lunchbox raided. All their sanwiches AND their chocolate cake - gone! Gave a description of the culprit to the police. Short, feathery, pale, a bit beaky........."

"Oh - but why are we here now?

"This is an identity parade. The lunchbox owner's out there looking at us. Reckons he can pick the culprit out in a line-up...."

"Ooh-err - are there any crumbs round my beak...?"
