Norfolk Island Kaka (Nestor productus)
The Norfolk Island Kaka was described in 1836, it was restricted to the Norfolk Islands, where it was the largest parrot species.
The species reached a size of about 33 cm, it was rather variable but was mainly very bright yellow and brick red colored on the underside, while the upper side was mainly dark brown. The beak was very much elongated and several specimens show strange bill deformities.
The Norfolk Island Kaka disappeared due to overhunting.
