With its striking black-and-white plumage, vivid red bill and evocative piping call, the Australian Pied Oystercatcher is familiar to many people who visit our beaches. The species occurs around almost the entire coastline of Australia, inhabiting sandy beaches and mudflats. Oystercatchers are typically seen probing the sand or mud with their long bills in search of sandworms, molluscs or crabs, sometimes hammering at their shells.
