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.

To the north they are very unlucky with predation before the eggs even hatch out, but to the south the eggs hatch out and then the predation occurs on the chicks. The main problem appears to be feral cats, but there is also predation from birds of prey and the parent Pied Oystercatchers do their utmost to protect their young.

This year is the eighteenth year since we discovered our first Pied Oystercatcher nest on Cable Beach in Broome and it didn’t take us long to realise that they are not at all successful at raising young due to egg and chick predation.

Nearly 90% of the nests failed during egg stage, mainly due to strong winds and depredation by American mink Neovison vison. We analyse possible causes for the decline of the population and propose conservation actions to protect this species. Roesler, I, Imberti, S, Casanas, H, Mahler, B, & Reboreda, JC (2012).

After 28 days of sharing the duty of sitting on three eggs we finally had the arrival of our first Pied Oystercatcher chicks for 2012 on Friday August 3rd. It is unusual for three eggs to be laid here in Broome and many eggs do not even hatch due to predation each season.

As a Northeast birder I am familiar with the alarming decrease in the number of Red Knots along Atlantic shores and have signed petitions and written e-mails calling for legislation and rules that will limit the overharvesting of the horseshoe crab, whose eggs Red Knots depend on.
