Chatham Island kaka

The Chatham kaka or Chatham Island kaka (Nestor chathamensis) is an extinct parrot species previously found on the Chatham Islands, New Zealand. The first individuals were thought to belong to the kaka (Nestor meridionalis), but detailed examination of the subfossil bones showed that they actually belong to a separate endemic species. The species became extinct within the first 150 years of the arrival of the Polynesians around 1550, long before any European settlers. No skins or descriptions are available.
