You said that number of the noisy miners dropped from 20 to 6? So maybe food competition is not such a threat anymore but reproductive predation and predation in general is. Hence they've stopped harrassing their food competitors (other honeyeaters) and started even on their resident predators sespecially those ones (such as Butcherbirds) which will kill the young ones that the group will inevitably need to produce in good numbers this spring. How that explains the Goshawk, I don't know ... maybe they don't feel they have the numbers anymore.

Thanks for the notes on storm impacts: what's very interesting, as you so clearly point out, is the apparent "suspension" of the usual territorial
arrangements, and animosities.

I've definitely noticed similar adjustments in bird groups around areas of Newcastle and Lake Macquarie: the litmus test for me are the Noisy Miners. Now, maybe it's because I've suddenly turned to watching them work very closely, but it appears they are still not following their conventional visitor expulsion routines. Certainly warning calls are issued whenever a Goshawk and similar are out and about, but something has changed in the resident band's hierarchies. They're letting in yellow-faced honeyeaters who were previously sent packing as soon as they so much as looked at a flower, but the Noisies are harassing resident Grey Butcherbirds that were
usually "ignored".
