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 246 (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.
