It has been a few years since I could share some good news about the Pied Oystercatchers breeding along the coast near Broome. Hopefully you won’t mind me writing a bit more this year about Pied Oystercatchers during the breeding season! The two eggs normally hatch at least a day apart and sometimes longer.

The European Breeding Bird Atlas 2 makes interesting reading. Originally confined to the Arctic, breeding [of Barnacle Geese] is now confirmed throughout much of the Baltic coast S North Sea. A pair did lay infertile eggs in Iceland in 2018, but that’s about the only record I can find).

With populations plunging dramatically over the last decade, researchers from the Wildfowl and Wetlands Trust, Birds Russia, and a number of other conservation organizations made the always-controversial call to pluck eggs from the imperiled wild population and establish a captive breeding program as a final hedge against extinction.

Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Egg collection for local consumption still continues at lower scale. The initial decline in the Andean Flamingo’s population appears to have started as early as the mid 20th Century.

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.

However, the lockdown forces me to go deeper and deeper into my photo collection, if I want to write anything at all. Contrary to alleged preferences among humans, the golden-headed cisticola has a shorter tail during the breeding season ( source ). It breeds in tree holes, presumably explaining the more commonly used name for it.

She also monitors Pied Oystercatchers breeding along a 23km stretch of beach by bicycle and on foot.

It is listed as vulnerable, though its rather rigorous treatment of the second, smaller chick in a clutch (it starves to death within 1 week, rarely a month, according to the HBW) offers the potential for collecting second-hatched chicks for reintroduction programs.
