The Chatham kaka ( Nestor chathamensis ) is an extinct parrot that was endemic to the Chatham Islands , New Zealand .

The first individuals were mistakenly identified as specimens of the kaka , but detailed studies on subfossil bones revealed that they belong to a species of their own.

After Polynesians settled on the island around 1550 , it was less than 150 years and the Chatham kaka was extinct. More detailed descriptions, bellows or feathers are no longer preserved today.

Classification

The Chatham kaka belongs to the genus Nestor in the family Nestoridae , a small group of parrots that are native to New Zealand. It is considered more closely related to the kaka ( Nestor meridionalis ) and the also extinct Norfolk kaka ( Nestor productus ) than to the kea ( Nestor notabilis ).

ecology

The Chatham kaka was a forest parrot with a wider pelvis and longer legs than the North Island kaka Nestor meridionalis septentrionalis . As with many other bird species endemic to New Zealand, the Chatham kaka had no natural predators. It is also believed that, like the kakapo , he was a bad flier.
