Of the nine species in the New Zealand parrot superfamily Strigopoidea, the Norfolk kākā[1][2] and Chatham kākā[3] became extinct in recent history. The last known individual of the Norfolk Kākā died in its cage in London sometime after 1851,[4] and only between seven[5] and 20[6] skins survive. The Chatham Kākā became extinct in pre-European times, after Polynesians settled the island, between 1550 and 1700, and is only known from subfossil bones.[3] Of the surviving species, the kākāpō is critically endangered,[7][8] with living individuals numbering only 244 (as of 2024).[9] The mainland kākā is listed as endangered,[10][11] and the kea is listed as vulnerable.[12][13] The Nestoridae genus Nelepsittacus consists of four extinct species.
Species list
Nestoridae
There are two surviving species and at least one well documented extinct species of the family Nestoridae. Very little is known about the Chatham Kākā, and it may have been con-specific with another Kākā species, or a separate species belonging to the genus.
