Curious connection there. That would seem odd that Nine-primaried oscines would behave any different from ten-primaried oscines Actually I am not sufficiently involved in that taxonomic character to remember which birds were in which group. So I looked at the link that Martin provided and by my quick reading of it, I suspect that none of our native (Australian) passerines are in the Nine-primaried oscines group. Going by the families listed, and thinking for about 10 seconds, I believe that the only wild birds we have in Australia that would be Nine-primaried oscines would be the Goldfinch and Greenfinch. So I think it is not very relevant.
Anyway I think that Canberra area shows the pattern of behaviour very well.
I would be surprised if we could settle on one nuclear species. Surely that is variable as are the other components.

According to the version I have accessed http://en.wikipedia.org/wiki/Mixed-species_foraging_flock was last updated on 29 April 2011 so it is possibly not that out of date. Its content is however very dense and I couldn't really make much sense of it. This may be because I am averse to terms such as "Nine-primaried oscines" or possibly because it seemed to be heavily focussed on the tropics.
I wonder whether what we term "mixed feeding flocks " are not more like (quoting from that Wikipedia article) " feeding aggregations, which are congregations of several species of bird at areas of locally high food availability." Googling the "feeding aggregations" term gave little of relevance to this discussion.
I googled ‘’Mixed-species foraging flock’’ and the most commonly cited "scholarly" article was http://www.jstor.org/pss/1942443 from 1969. As with most scholarly articles it is not available to mortals outside the gleaming halls of academe (unless one pays an exorbitant fee) but hopefully the abstract will give the idea.
