Fun facts

  • Its metallic, piercing call, given above all in flight and at dawn, is one of the most recognisable sounds of the Argentine, Chilean and Brazilian countryside.
  • It has benefited from irrigated farming and has expanded its range considerably in recent decades, colonising city parks and golf courses in several South American cities.
  • Its curved bill lets it probe soft ground several centimetres deep, locating grubs and worms by touch without needing to see them.
