This is always a problem with making the decision 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.

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.

This is one of the displays that the Hooded Plover 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.

I'll look up Michael Weston's PhD thesis "The 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!!

There has been a pair on that beach for some years now and like the other HPs in the park their nesting success rate is terrible.
