Of all birds it is probably the magpie that is most associated with superstitions. However, most superstitions regarding magpies are based around just one bird. Throughout Britain it is thought to be unlucky to see a lone magpie and there are a number of beliefs about what you should do to prevent bad luck.
In most parts of the UK it is believed that you should salute the single magpie and say “Good morning Mr Magpie. How is your lady wife today?” By acknowledging the magpie in this way you are showing him proper respect, so that he doesn’t curse you with his bad luck.
In Yorkshire magpies are associated with witchcraft and you should make a sign of the cross to ward off evil.

Rossini wrote a tragicomic opera entitled La Gazza Ladra (The Thieving Magpie) about a French girl accused of theft who is tried, convicted and executed. Later the true culprit is revealed to be a magpie and in remorse the town organises an annual ‘Mass Of The Magpies’ to pray for the girl’s soul.
