Non-Australians may be unfamiliar with the Australian magpie (Gymnorhyna tibicen) - a charming and intelligent creature except in the nesting season, when it can turn truly ferocious. The Macquarie Dictionary describes it as having 'a solid body, strong legs and a large pointed bill' - it could have added that the bill is made of stainless steel. In spring it's the bane of cyclists and pedestrians, and can open up your scalp or even take out an eye.
Now research shows that there's a splendid cure for magpie attack. Just get old.
