I
think Chris Davey or Jack Holland put it out that they say "quick", rather than
"chip". A description I appreciated. Or that is just an easy way to remember it.
I would not describe it as quiet, though. It can often be heard long before the
birds are visible, of course that depends on the terrain.
One
last comment, about: have any been seen flying along
the Murrumbidgee corridor? I think that most of the birds that flew that route
were killed in the 2008 fires, in Victoria. I suspect that their
populations build up very quickly and there would unlikely be any or much
residual impact on birds in the ACT from the birds
that flew that route were killed in the 2008 fires, in Victoria. The birds I get in Kambah have surely come along the
Murrumbidgee corridor in some way.

Hi Denis, Yes, well that was the closest approximation the
sound heard as I could offer readily via the Internet. The 'chip, chip' call
is certainly what I have been hearing with all the flocks. And nothing else.
So there you go. Case closed : - )

Hi DJFlotek I have just listened to the recording., The
calls in the first 30 seconds are what I would regard as "feeding calls" or
maybe proclaiming territory. Those calls are heard where the birds live in
summer, and also when feeding in migration grounds (eg, Banksia heathlands, or
coastal forests).
The flight calls on migration are quite different from the calls on that
recording. YFHEs make a quiet "chip, chip" call when migrating.
WNHE make a mewing call, when migrating. The calls are quite
distinctive (as Philip Veerman has suggested).
Both appear to serve as contact calls, not proclaiming territory (when
migrating).
