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

The kea is a species of large parrot in the family Strigopidae that is endemic to the forested and alpine regions of the South Island of New Zealand. About 48 cm (19 in) long, it is mostly olive-green, with brilliant orange under its wings and has a large, narrow, curved, grey-brown upper beak. Its omnivorous diet consists mainly of roots, leaves, berries, nectar, and insects, but also includes carrion. It was once killed for bounty due to concern by sheep-farmers that it attacked livestock, especially sheep. The kea is now uncommon, and received absolute protection under the Wildlife Act in 1986.
The kākāpō, sometimes known as the owl parrot or owl-faced parrot, is a species of large, nocturnal, ground-dwelling parrot of the superfamily Strigopoidea. It is endemic to New Zealand.
The genus Nestor is one of the two extant genera of the parrot family Strigopidae. Together with the kākāpō, and the extinct parrots in the genus Nelepsittacus, they form the parrot superfamily Strigopoidea. The Nestor's genus contains two extant parrot species from New Zealand and two extinct species from Norfolk Island, Australia and Chatham Island, New Zealand, respectively. All species are large stocky birds with short squarish tails. A defining characteristic of the genus is the tongue, which is tipped with a hair-like fringe. The superficial resemblance of this tongue to that of lorikeets has led some taxonomists to consider the two groups closely related, but DNA evidence shows they are not.
The red-vented cockatoo, also known as the Philippine cockatoo and locally katala, abukay, agay or kalangay, is a species of cockatoo. It is endemic to the Philippines formerly found throughout the entire country but due to the illegal wildlife trade it is now locally extinct in most of its range with the only sizeable population remaining in Palawan and Sulu Archipelago. There are remnant populations in Polillo Islands, Bohol and Samar. It is roughly the size and shape of the Tanimbar corella, but is easily distinguished by the red feathers around the vent. It is threatened by habitat loss and the cage-bird trade.
The New Zealand kākā is a large species of parrot of the family Strigopidae found in New Zealand's native forests across the three main Islands of New Zealand. The species is often known by the abbreviated name kākā, although it shares this name with the recently extinct Norfolk kākā and Chatham kākā. Two subspecies of New Zealand kākā are recognised. It is endangered and has disappeared from much of its former range, though the re-introduction of North Island kākā at Zealandia in Wellington has led to an increasing population of the birds across the city.
The Antipodes parakeet or Antipodes Island parakeet is a parrot in the family Psittaculidae that is endemic to the Antipodes Islands of New Zealand. It is one of two parrot species found on the islands, and one of only five ground-dwelling parrots in the world. They are long-living birds that may live up to 10 years of age, but the introduction of mice that compete with them for food was a threat to their survival on the Antipodes Islands until the mice were successfully eradicated from the Islands in 2016. Unusually for parrots, they sometimes prey upon other birds, a trait shared by another New Zealand parrot, the kea.
The Norfolk kākā 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 kākā.
The Banggai crow is a member of the crow family from Banggai regency in the province of Central Sulawesi in Indonesia. It is listed as critically endangered by IUCN. It was feared extinct, but was finally rediscovered during surveys on Peleng Island off the southeast coast of Sulawesi by Indonesian ornithologist Mochamad Indrawan in 2007 and 2008.
The Souss-Massa National Park is a 33,800 hectare national park on the Atlantic coast of Morocco which was created in 1991. It lies between Agadir to the north and Sidi Ifni to the south. The estuary of the Oued Souss is the northern limit of the park, the Oued Massa is near the center, and at the southern end is the town of Aglou. 30,000 ha of land near Aglou, south of the park, is also included in the site because it is sometimes used as a feeding area by the northern bald ibis. The habitat is grazed steppe with dunes, beaches and wetlands. The soil is mainly sandy with some rockier areas.
The New Zealand parrot family, Strigopidae, consists of at least three genera of parrots – Nestor, Strigops, the fossil Nelepsittacus, and probably the fossil Heracles. The genus Nestor consists of the kea, kākā, Norfolk kākā and Chatham kākā, while the genus Strigops contains the iconic kākāpō. All extant species are endemic to New Zealand. The species of the genus Nelepsittacus were endemics of the main islands, while the two extinct species of the genus Nestor were found at the nearby oceanic islands such as Chatham Island of New Zealand, and Norfolk Island and adjacent Phillip Island.
The Chatham kākā or Chatham Island kākā is an extinct parrot species previously found on the Chatham Islands, New Zealand. The first individuals were thought to belong to the New Zealand kākā, but detailed examination of the subfossil bones showed that they actually belong to a separate endemic species. The species became extinct within the first 150 years of the arrival of the Polynesians around 1500, long before any European settlers. No skins or descriptions are available.
Parrots (Psittaciformes), also known as psittacines, are birds with a strong curved beak, upright stance, and clawed feet. They are classified in four families that contain roughly 410 species in 101 genera, found mostly in tropical and subtropical regions. The four families are the Psittaculidae, Psittacidae, Cacatuoidea (cockatoos), and Strigopidae. One-third of all parrot species are threatened by extinction, with a higher aggregate extinction risk than any other comparable bird group. Parrots have a generally pantropical distribution with several species inhabiting temperate regions as well. The greatest diversity of parrots is in South America and Australasia.
New Zealand is geographically isolated, and originally lacked any mammalian predators, hence parrots evolved to fill habitats from the ground dwelling kākāpō to the alpine dwelling kea as well as a variety of forest species. The arrival of Māori, then European settlers with their attendant animals, habitat destruction and even deliberate targeting, has resulted in their numbers plummeting. Today one species is on the brink of extinction and three other species range from Vulnerable to Critically Endangered, all impacted by invasive species. Further parrot species were not introduced by acclimatisation societies, but occasional releases, both deliberate and accidental, have resulted in self-sustaining populations of some Australian species. New Zealand was identified among the highest priority countries for parrot conservation in the world, due to its parrot diversity, endemism, threats, and having more threatened parrot species than expected.
