Spotted something wrong?

The belly is white, with a white wedge separating the dark breast from the edge of the folded wing. In flight it shows a white band on the secondaries. The legs are pale pink.

Fun facts

  • Its epithet palliatus means "wrapped in a cloak", from the contrast between the brown back and the rest of the plumage.
  • It feeds at low tide and rests at high tide: its day is set by the sea, not by the sun.
  • It hybridises with the South American blackish oystercatcher and with the North American black oystercatcher where their ranges overlap, and those hybrids are recorded as taxa in their own right in the databases.
