I have both here. The rainbow lorikeets are more than a match for the cockies, but they aren't here all the time, and the cockies are. Both of them drive off the king parrots, which I love.
I call the lorikeets 'angry birds', as they take on anything, including wattle birds, butcher birds, maggies and currawongs.
I have so many cockies here, I wish that they ate possums.....
