When I was a teenager I was woken one early morning by something moving around on my chest. I opened my eyes only to be faced by a magpie bill two inches off the end of my nose, ready to make an eye-strike.
I shouted, threw the bedclothes up and it flew out of the open window.
Turned out it was a hand reared pet which had been released to fly free - of course it had lost its innate fear of people.
It didn't last long - it annoyed a few other people and ended up caught in a trap with a wrung neck.
Bastard thing
