The New Zealand parrot family, Strigopidae,

endemic to New Zealand.[7] 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

The family diverged from the other parrots around 82 million years ago when New Zealand broke off from Gondwana, while the ancestors of the genera Nestor and Strigops diverged from each other between 60 and 80 million years ago.[16][17]

Systematics

No consensus existed regarding the taxonomy of

true parrots).[19] While some taxonomists include three genera (Nestor, Nelepsittacus, and Strigops) in the family Strigopidae, others place Nestor and Nelepsittacus in the Nestoridae and retain only Strigops in the Strigopidae.[19][20] Traditionally, the species of the family Strigopoidea were placed in the superfamily Psittacoidea, but several studies confirmed the unique placement of this group at the base of the parrot tree.[16][19][21][22]

Phylogeography

An unproven hypothesis for the

Island species diverge rapidly from mainland species once a few vagrants arrive at a suitable island. Both the Norfolk kākā and the Chatham kākā are the result of migration of a limited number of individuals to islands and subsequent adaptation to the habitat of those islands.[17] The lack of DNA material for the Chatham kākā makes it difficult to establish precisely when those speciation events occurred. Finally, in recent times, the kākā populations at the North Island and South Island became isolated from each other due to the rise in sea levels when the continental glaciers melted at the end of the Pleistocene.[17]

Until modern times, New Zealand and the surrounding islands were not inhabited by four-legged mammals, an environment that enabled some birds to make nests on the ground and others to be flightless without fear of predation.

The parakeet species belonging to the genus Cyanoramphus (kākāriki) belong to the true parrot family Psittacidae and are closely related to the endemic genus Eunymphicus from New Caledonia. They may have reached New Zealand between 450,000 and 625,000 years ago from mainland Australia by way of New Caledonia, but this is disputed.[23]

Common names

Current distribution of extant species, as well as previous distribution of extinct island species.[27]

All common names for species in this family are the same as the traditional

onomatopoeic of its kee-aah call.[5][36]

Ecology

Kea are well adapted to life in the alpine zone, like these in the Southern Alps. The highest mountain in New Zealand, Aoraki / Mount Cook, is in the background.

The isolated location of New Zealand has made it difficult for mammals to reach the island. This is reflected in the absence of

) to the island. Later, Europeans introduced many more species, including large herbivores and mammalian predators.

The three extant species of this family occupy rather different ecological niches, a result of the phylogeographical dynamics of this family. The kākāpō is a

) mast abundantly.

The kea is well adapted to life at high altitudes, and they are regularly observed in the snow at ski resorts. As trees are absent in the alpine zone, they breed in hollows in the ground instead of in tree hollows like most parrot species.

Relationship with humans

Importance to the Māori

The parrots were important to the Māori in various ways. They hunted them for food, kept them as pets, and used their feathers in weaving

kahu huruhuru (feather cloak).[38] Feathers were also used to decorate the head of the taiaha, a Māori weapon, but were removed prior to battle.[39] The skins of the kākāpō with the feathers attached were used to make cloaks (kākahu) and dress capes (kahu kākāpō), especially for the wives and daughters of chiefs.[39] Māori like to refer to the kākā in the tauparapara, the incantation to begin their mihi (tribute), because their voice (reo) is continuous.[40][41]

Status

Of the five species, the Norfolk kākā

subfossil bones.[8] Of the surviving species, the kākāpō is critically endangered,[10][30] with living individuals numbering only 247 as of 2023.[45] The mainland kākā is listed as endangered,[11][28] alongside the kea
.

Threats

The fauna of New Zealand evolved in the total absence of humans and other mammals. Only a few bat species and sea mammals were present prior to colonisation by humans, and the only predators were birds of prey that hunt by sight. These circumstances influence the design of New Zealand's parrots, for example, the flightlessness of the kākāpō and the ground breeding of the kea.[39] Polynesians arrived at Aotearoa between 800 and 1300 AD,[46] and introduced the kurī (dog) and kiore (Polynesian rat) to the islands.[39][47] This was disastrous for the native fauna, because mammalian predators can locate prey by scent, and the native fauna had no defence against them.[39]

The kākāpō was hunted for its meat, skin, and plumage. When the first European settlers arrived, the kākāpō was already declining, but still widespread.[39] The large-scale clearance of forests and bush destroyed its habitat while introduced predators such as rats, cats, and stoats found the flightless, ground-nesting birds easy prey.

The New Zealand kākā needs large tracts of forest to thrive, and the continued fragmentation of forests due to agriculture and logging has a devastating effect on this species. Another threat comes from competition with introduced species for food, for example with possums for the endemic mistletoe and rata and with wasps for shimmering honeydew, an excretion of scale insects. Females, young, and eggs are particularly vulnerable in the tree hollows in which they nest.

The kea nests in holes in the ground, again making it vulnerable to introduced predators. Another major threat, resulting from development of the alpine zone, is their opportunistic reliance on human food sources as their natural food sources dwindle.[15]

Conservation

Recovery programs for the kākāpō and the kākā have been established, while the kea is also closely monitored.[48] The 247 as of 2023.[49] living kākāpō are all in a breeding and conservation program. Each one has been individually named.
