Katlaughing, your magpies are quite different from our Oz ones, as has been said before. I didn't realise how different till I heard your sound clip. Our magpie is much more melodic - magpie sounds - and is all black and white, like this.

All this talk of "pie" as a verb reminds me of one of the songs I used to have to sing when I was a kid. I say "have to" because I sang in competitions and I found the choices really BORING! It was an adaptation of one of Shakespeare's verses, called "When daisies pied". I did know pie wasn't a verb, but I used to try and make a joke out of it to relieve the monotony, saying things like "I've never seen a daisy PIE. What does it do when it PIES?"

Which of course leads to PIE!!!
