The only fact that makes it illegal is that the birds (doesn't matter what kind) are being attracted in by offering them food.

You are in effect cancelling out any reason to shoot to protect other birds as it's you that is causing the problem.

It matters not to me if someone wants to take the chance and shoot Magpies under the circumstances described. It will be them that faces any prosecution and also risks their rifles being taken for test.

Sure it may not happen but if it does you are in deep trouble. Just like the bloke who was shooting ferals (in compliance to the General Licence). Pellet left his boundary (new law), rifles taken for test and one with AT fitted was over. Criminal record, loss of rifle and costs.

Baiting birds in and shooting them has been successfully prosecuted before and will be again.
