In the case of the two pairs of Pied Oystercatchers that did actually hatch their eggs and have chicks for a few days they did lay once more, but then they failed to even hatch the second clutch and then no longer attempted to breed. In 2007 one Pied Oystercatcher was fledged along this stretch of beach and none succeeded in 2009.

In 2000, around 1,000 breeding pairs were known, but by 2009, the number had plummeted to just 120-220 pairs, a decline of 88%. During that time, adult survival appeared unchanged and breeding success was reasonable, but the recruitment of young birds back into the adult population was zero in all but one of the years studied.
