Australian Pied Oystercatcher

Haematopus longirostris

Did You Know?

  • Oystercatchers are experts at catching sand worms that fisherman prize for bait.
  • A breeding pair typically reuses a nest site over many years and will rarely change its nesting area.

A medium shorebird with long skinny legs and a long beak. The Oystercatcher has a black head and black with a white belly, orange-red eyes, and very distinctive orange legs and beak.

Size

50 cm long (from head to tail)

Behaviour

Diet

These shorebirds feed on bivalve molluscs prised apart with specially adapted bills. Food is found by probing their long, chisel-shaped bills in the mud. Oystercatchers are one of the few waders that feed their young with this specialised feeding technique.

Breeding

Breeds in pairs with a territory of 200 m defended by both birds. Both sexes share parenting duties. They nest on the sand just above high water mark on beaches, sandbars, margins of estuaries and lagoons. Eggs are well-camouflaged, pale brown with darker brown and black blotches and streaks.

Climate Adaptations

Australian pied oystercatchers nest on the upper parts of sandy beaches and are one of the main predators for pipis (marine bivalves) and beach invertebrates. This makes them vulnerable to the effects of sea level rise, storm surges and overuse by humans. They are listed as vulnerable by the NSW government and scientists are worried that their numbers are slowly decreasing in the wild.

Similar Species

Sooty oystercatcher (Haematopus fuliginosus), look similar to the pied oystercatcher, and can often co-occur on the same beach. The sooty oystercatcher lacks the white feathers and although their beaks and legs are dark red their bodies are completely black.
