As for females initiating courtship in human populations -- I don't think it's just a nordic thing, I think it's an equality thing. I'm sure you'll find (sub)cultures most places where women are more active -- and I'm guessing that on balance those are (sub)cultures that are in general more gender-equal.
But, as I've lived (and dated, pitiful as my exploits are) mostly in Norway -- I might be biased :-)
