Alan,
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".
cheers
Craig
