A question...

I've been meaning to join here for some time, but it always slipped my mind. But having a question finally got me around to doing it. :)

It's a bit of an odd question, but I was hoping someone could help me in translating "little magpie" to Norwegian, preferably Nynorsk. I know the word "skjor," but I'm not clear on diminutives. :/

I'd be very grateful, and thanks in advance!
