Hi Laurie,
As someone who has done a little bit of work, including banding and
flagging, on Bush Stone-curlews in north-east New South Wales I have often
pondered your question. The prevalence of foxes is the most likely answer
as these invasive predators get scarcer the further north you go. The fact
that the Stone-curlews breed around humans may reflect the lack of, or low
number of, foxes in these areas. There has been an apparent increase in the
population of this species in northern New South Wales, in particular the
Tweed and Clarence Valleys, but it is not known whether this increase is
real or whether it is a result of greater observation effort. The control
of foxes may also help to explain the increase as fox control has been
carried out by the National Parks & Wildlife Service (as part of their Fox
Threat Abatement Plans) and local councils in the area (and probably by the
Local Land Services as well).
Regards
Greg

It would be interesting to know what is really behind the decline in Bush
Thickknees down south. They are doing quite well in Queensland - they are
regulars in inner Brisbane, and back yards on the Bay Islands, so they can
handle suburban environments.
I’ve been watching a nesting pair in the inner city - one chick hatched a
few days ago, but the adults were staying put, which I guess means there was
another one yet to hatch. That is interesting, as I would have thought the
eggs would have hatched around the same time.
Regards, Laurie.
