ClimateWatch Science Advisor

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. Australian pied oystercatchers are listed as vulnerable by the NSW government and scientists are worried that their numbers are slowly decreasing in the wild. 

When To Look

Throughout the year

Where To Look

  • Mudflats, sandbanks and sandy ocean beaches 
  • They are often found in pairs
  • Throughout Australia 


The map below displays the accumulated observations of these species as reported by ClimateWatch observers, together with the layer showing how the range of the species might change between now and 2085, with orange areas indicating where the species might disappear, and green areas where the species range might expand.

  1. What Else?

    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.

  1. Did You Know?

    A breeding pair typically reuses a nest site over many years and will rarely change its nesting area.

    Oystercatchers are experts at catching sand worms that fisherman prize for bait.
