The breeding season in the north of Australia starts from about July 1st and there are often several attempts if the eggs fail, are lost or the chicks don’t survive. On July 1st 2007 an egg was laid by a Pied Oystercatcher that was known to be an adult in 2002 and had been banded in nearby Roebuck Bay. Hermit Crab in lid.

They usually have their first eggs in place by the first week in July each year and they sit on them for 28 days. The first egg is laid followed by the second the next day and then they sit fairly continuously despite the warm day time temperature. On rare occasions we have had three eggs in a nest, but this is unusual in this area.

In this system, females mate and lay eggs with multiple males over the course of a breeding season, leaving males to incubate the eggs and raise the chicks. In polygynandrous systems, broods may be raised by groups of males (either with or without the help of females) (Briskie 1992, 2009, Nakamura 1998). 1996, Nakamura 1998).

Are there birders out there who do not dream of birding Australia? Possibly birders who have already birded Australia (but, wouldn’t you want to go back?)

Egg loss to predation has been extraordinarily bad this year and all of the nests mentioned in the last post were lost and all of the pairs of Pied Oystercatchers laid a new clutch of eggs. In fact they have not just laid once again, but many pairs have laid up to five clutches of eggs this season.

In theory the eggs are laid, the adults share the incubation of the eggs for 28 days and then fluffy chicks emerge. There are other pairs that nest in rather obscure areas, but as soon as the eggs hatch they walk the chicks several kilometres to a better feeding area. If only it was that easy!

The first eggs are laid during the first week of July each year and if these eggs fail to hatch or the chicks are lost they will lay further eggs within a few weeks. We had one pair attempt 5 times in 2009, so they don’t give up easily! Nest site with 3 eggs-one white!
