DescriptionSouth island kokako distribution map.svg
English: The map above provides an estimated historical distribution of the South Island kōkako (Callaeas cinereus), along with the last two generally accepted sightings. Two distributions are shown: the estimated maximum extent of the kōkako (greyish-green) based on fossil records, and the estimated extent by the period of European settlement (green) based on settler records.
The 1967 sighting is often regarded to be the last accurate sighting of a South Island kōkako in the 20th century. The 2007 sighting has been accepted by the Ornithological Society of New Zealand (OSNZ) Records Appraisal Committee.
