Hi Darryl
> Thanks Val for the invaluable info regarding
the behaviour of the parent

whether or not to put uptemporary beach closure signs. If all members
of the public come up to read the sign then hang around [or even worse
ignore the sign] then it is best not to put up a sign.

As for the Red-capped > Plover, I've photographed these birds before and have had them approach > me at a distance of 4M. So they're very nervy in comparison. Not more nervy in comparison when they are not
nesting. However if you saw the HPs doing a typical head bob [they don't
head bob all the time] they most likely had chicks on the beach. And if
they did 4 metres is far too close to be to them as they send the chicks to
ground which means that the chicks don't feed and don't get brooded.
I find that the 'safe distance' for Hooded Plovers
with chicks varies quite a lot. When I am checking for
chicks I sometimes have to move so far away that I have trouble observing
even with binoculars - they won't let their chicks move around until they have
decided it is safe to do so.
> Well what other people that I've spoken to

uses but usually as a last resort [I have observed them doing it to try to
distract a Nankeen Kestrel]. Their preferred distraction display is
running along the beach ahead of you.

effect of disturbance on the breeding biology of Hooded Plovers" and get back to
you.

They are the very ideal however they are very very
popular with the public!!

now and like the other HPs in the park their nesting success rate is
terrible.
