Fun facts

  • The whole species lives in a few ravines on an island of 50 square kilometres: it is one of the smallest ranges of any bird in the world.
  • Alejandro Selkirk Island is named after the sailor whose shipwreck in the archipelago inspired Robinson Crusoe, although he was in fact on the neighbouring island.
  • It nests in holes in tree ferns and in cavities in trunks, and conservation projects install rat-proof nest boxes to raise its breeding success.
