What’s a ‘banger’?

You refer to setting up ‘bangers’ to move the birds off another field in the last feature. What do you mean and where can I get them?

ANDY CROW replies: Banger ropes are available from specialist agricultural suppliers. As the name suggests, they are literally a rope with a number of bangers fixed to it. You fix the rope to a tree or post, light one end and the bangs are designed to go off roughly every 30 minutes and last for about six hours. I like the ‘magnum’ ones as they are louder. A box of 12 ropes costs about £50.
