Psittaciformes - Nestor Productus

Nestor

The Norfolk kaka (Nestor productus) is an extinct species of large parrot, belonging to the parrot family Nestoridae. The birds were about 38 cm long, with mostly olive-brown upperparts, (reddish-)orange cheeks and throat, straw-coloured breast, thighs, rump and lower abdomen dark orange and a prominent beak. It inhabited the rocks and treetops of Norfolk Island and adjacent Phillip Island. It was a relative of the New Zealand 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 specie. 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.
