Last year whilst working in a customers house , the lady of the house came in really upset(crying) She had been hanging out her washing and spotted a half dead woodpigeon chick in the garden with its eyes pecked out and compleatley bald on its head and bleeding.She asked if i could put it out of its misery, which i did. 30 minutes later her husband came home and she told him what had happened. He proceded to tell me how the last few days before he had been throwing stones/sticks ect at a group of magpies trying to raid the nest (which was in a tree in his garden)

Magpies imo are vermin to be classified in the same bracket as rats .
I wouldnt hesitate to shoot a few given a chance
