The Lord Howe Island Parakeet(Cyanoramphus subflavescens) was a medium-sized green parrot with a head bright green, the crown crimson red in color and a stripe on the eyes; the eyes were red and bill grey. The upperparts They were bright green with a dark red spot on each side of the rump (usually they are hidden by the wings when resting) and a blue border in wings; the underparts were yellowish green.
Both sexes looked similar, but the female It was smaller.
Taxonomic status:
This taxon is considered a subspecies of Cyanoramphus [novaezelandiae or subflavescens] (sensu lato) by some authors.
In 2012, World Bird List of IOC recognized him as a species [IOC world birdnames Archived 2012-08-06 at the Wayback Machine.].
Habitat:
The Lord Howe Island Parakeet It was occasionally observed in flocks. There is little information on their habitats, They probably lived in inhabited forests and cultivated areas of the Lord Howe Island. No information on the use of different habitats for different activities.
Reproduction:
Nothing is known of sexual maturity, life expectancy and natural mortality of this extinct species. But, It has been estimated that the useful life of the Lord Howe Island Parakeet should be similar to the Norfolk Island Parakeet(Cyanoramphus cookii), About three years. the age of sexual maturity is also known populations of this species, although a juvenile female was seen mating with a male just a week after achieving independence, and captive birds are said to have bred when they were less than a year old.
Little else is known of the breeding of the Lord Howe Island Parakeet, probably reproduced in response to weather conditions and food availability, nesting in tree holes or hollow pipes, in crevices between rocks or cliffs.
Food:
Meal Lord Howe Island Parakeet probably consisted of plant material, as seeds, fruit, buds and leaves of native trees and shrubs. Other extant populations ate mainly seeds, fruits and berries, egg yolks, sprouts and flowers, as well as, occasionally, a small number of invertebrates.
โข The last record of this species dates from 1869. EXTINCT.
The population declines were mainly due to habitat modification, hunting, poisoning, and the introduction of predators (especially cats and rats).
But, the main threat to the Lord Howe Island Parakeet was the hunting and its capture by settlers. Formerly he abounded in the Lord Howe Island and it was said to be a plague, since it destroyed the crops and orchards of the inhabitants of the island.
There are only two copies of Lord Howe Island Parakeet.

โท The world of Pets: Dogs, cats, birds, reptiles, amphibians
The Chatham Parakeet(Cyanoramphus forbesi) They are one of the two medium bright green parrots of Chatham Islands. Although they look very similar to those Yellow-crowned parakeet(Cyanoramphus auriceps) of New Zealand continental, the color of the crown is not a reliable indicator of taxonomic relationships.
The Chatham Parakeet They are medium-sized parrots, of tail long, with wings wide and rounded and plumage predominantly emerald. have a crown bright yellow front and a crimson front band that does not reach to the eyes, unlike in the Red-crowned parakeet. Males are larger than the females.
taxonomy:
Since 1930 is commonly treated as a subspecies of the Yellow-crowned parakeet(Cyanoramphus auriceps), and clearly the two are closely related; the species differ, However, in size considerably, It is larger species Cyanoramphus forbesi. Currently considered Monotypic.
Habitat:
The Chatham Parakeet They are at higher densities in forests and dense vegetation regenerating areas than in open grassland. Despite its rather erratic flight, They fly hard and move easily between islas Mangere and little Mangere. Occasionally they have been observed Chatham Parakeet individual in the forests of southern Chatham Island (> 20 km from the Mangere Island) and nearby islands Pitt and owner. Their social behavior is similar to other species of parakeets Cyanoramphus. They are strongly territorial around nests, calling loudly and chasing intruders from nearby.
Reproduction:
The Chatham Parakeet have a long breeding season, with eggs laid between October and March. Son nesters cavity, preferring tree holes but also using rock crevices and under dense vegetation. The size medium of laying is of 5 eggs. Like all the other parakeets Cyanoramphus, females are responsible for preparing the nest, incubation, rearing and feeding the chicks until the 10-14 days old. During this period all your food is provided by your partner.. From then on, male and female parrots feed the chicks in the nest until they leave the nest.
The incubation usually begins after the start of the second egg, resulting in chicks within a clutch that vary greatly in age and size. The last chicks to hatch are usually born at a younger age and are less developed than their older brothers.. More than one brood may be attempted if the initial nest fails or if the food supply allows..
Food:
The foods consumed by Chatham Parakeet They are affected by seasonal availability, and include seeds, flowers and leaves of various plants, It is the most important invertebrates in spring. They feed extensively in soil in open areas.
Distribution and status:
Sw extension of its distribution area (reproduction / resident): 3 km2
The Chatham Parakeet It is restricted to of Tapuaenuku ISLA ISLA Pequeรฑa Mangere and Mangere in the Group of chatham islands, New Zealand. In 1930 He quenched in Mangere Island, but in 1973 had recolonized and numbered 40 birds and a small number of hybrids with the subspecies Cyanoramphus novaezelandiae chathamensis (of which there were 12 on the island) (Higgins 1999).
In 1996, two estimates indicated that the population of the Mangere Island It was from 50 to 120 Purebred birds. The population on the small island of little Mangere It is little known because the few visits made (H. Aikman a slightly. 1999). In 1999, it was estimated that the total population was about 120 birds(Aikman et al. 2001), but studies 2003 estimated 900 individuals on Isla Mangere(Aikman y Miskelly 2004, D. Houston y C. Miskelly a slightly. 2008).
A recent study estimated that more than 50% of the population of parakeets in Isla Mangere consisted of individuals hybrids (Chan et al. 2006), but this is expected to decrease due to mating positive range (T. Greene a slightly. 2012); the number of phenotypes forbes It is approaching the threshold management 10% (D. Houston a slightly. 2012) (that is to say, the number above which culling can be resumed as a management tool). There have been birds visiting South isla Chatham, the Pitt island and ISLA ISLA Chief of Sudeste(Taylor 1998, D. Houston y C. Miskelly a slightly. 2008, T. Greene a slightly. 2012).
Conservation:
โข Current category of the Red List of the UICN: Vulnerable.
โข Population trend: Stable.
โข Population size : 250-999 individuals. Rationale for the Red List category
This species may still have a small purebred adult population.. Possible removal by hybridization has been avoided thanks to three decades of conservation efforts, which they have seen increasing population size. It is restricted to one place (given the proximity of the small islands that lives and mobility), and its small population size means it still deserves to be listed in a threatened category, but it is likely that their population size has been more than 250 mature for more than 5 years, so it has been transferred to the category of Vulnerable.
Justification of the population
The population of phenotypes similar to those of Forbes It has increased dramatically in the Mangere Island, with the best estimates placing the population between 800 and 1.000 individuals. A survey in 2011 It assessed that the phenotypes of interest are in the 10%, the trigger level for management action (D. Houston a slightly. 2012). It is likely that populations have exceeded 250 mature for more than 5 years, so now it is in the range of 250-999 mature individuals.
Justification trend
The population has shown minor fluctuations in recent years, since the species recolonized the Mangere Island over the years 70 and it has benefited from habitat restoration, while hybridization has also suffered. In general, It is estimated that the population has remained stable for the last ten years, and It is probably increasing(T. Greene a slightly. 2012).
Threats
โข Disappeared from Mangere Island due to a combination of deforestation for grazing, decades of burning, the effects of introduced grazing mammals and predation by feral cats (Higgins 1999).
โข The greatest current threat is the hybridization with the Cyanoramphus novaezelandiae chathamensis, subspecies Red-crowned parakeet(Cyanoramphus novaezelandiae) What, despite the sacrifice, still it is settling in Mangere Island(J. Kearvell a slightly. 1999).
โข It is believed that the rate of hybridization High above is the result of the then low population sizes of the two species (D. Houston y C. Miskelly a slightly. 2008).
โข The levels of hybridization They have remained below 10% of the total population of parakeets Mangere Island over the last decade, so no management intervention was not necessary.
Conservation Actions Underway
โข Appendix I and II of CITES. The Mangere Island It has been substantially replanted (Aikman et al. 2001, D. Houston y C. Miskelly a slightly. 2008).
โข An ecological and genetic research program has investigated population dynamics, the hybridization and selection of partners (H. Aikman a slightly. 1999, Chan et al. 2006).
โข During 1976-1999, hybrid birds and individuals of the subspecies Cyanoramphus novaezelandiae chathamensis They were sacrificed population (Nixon 1994).
โข In 1998, 40 hybrids And six Cyanoramphus novaezelandiae chathamensis were killed, leaving 10 copies between hybrids and Cyanoramphus novaezelandiae chathamensis after the operation (H. Aikman a slightly. 1999).
โข Surveys of the relative proportion of hybrids regarding type phenotypes Forbes They are held every two years (D. Houston a slightly. 2012).
โข The translocation a fenced area predator proof in Chatham Island It is planned for 2017 (D. Houston a slightly. 2012).
Conservation Actions Proposed
โข Complete the investigation ecological, biological and genetic, including analysis and dissemination of results.
โข Monitor trends in the extent and quality of forest habitats on the island of Mangere.
โข Restore forest habitats Mangere Island to increase the number and reduce the hybridization.
โข Work for the establishment of one or more populations in the Chatham Island(H. Aikman a slightly. 1999).

The Reischek's Parakeet(Cyanoramphus hochstetteri). They are named after the Austrian ornithologist and taxidermist ยซAndreas Reischekยซ, the first scientist to visit the Antipodes Islands. He was a passenger of Stella and reached the Antipodes Islands in February 1888.
It is one of two species of parakeets Cyanoramphus who live in remote Antipodes Islands. It is a medium-sized green parrot, brightly colored, the outer flight feathers are light blue with a crown red, which looks a lot like other parakeets of "red crown" (for example, Cyanoramphus novaezelandiae). But appearances are deceptive. Genetic studies reveal that crown color may not be a good indicator of parakeet taxonomy, and the tiny Malherbe's parakeet(Cyanoramphus malherbi) It may be the closest relative of Reischek's Parakeet. It is common in all Antipodes Islands, particularly in more open areas and along shorelines close to penguin colonies.
The Reischek's Parakeet They are more abundant than Antipodes parakeet(Cyanoramphus unicolor) in most habitats. Significant differences were observed in diet between the two species of parakeets. are also evident strong seasonal and annual differences in diet related food availability. The Reischek's Parakeet They are strong fliers and have been observed flying between islands within the Antipodes group.
Social behavior is similar to other species of parakeets Cyanoramphus, but have been observed to spend considerable periods basking and preening in sheltered areas. Like other species Cyanoramphus, are strongly territorial around nests, and they call loudly and chase intruders from nearby.
They are usually found in pairs or, more commonly, in small groups that feed on or near the ground. You can often see them in meetings springs and wells isolated. Occasionally they flock fly to neighboring islands in search of food.
Reproduction:
We know relatively little about the breeding of the Reischek's Parakeet. Apparently nest from October to March inside tunnels modified or built inside the bases of groups of tussocks or ferns. The nest is lined with small pieces of wood, feathers, moss, herbs and other dry materials. They can reuse nests each year.
clutch size is unknown in nature. Its ecology and reproductive behavior are likely to be similar to those of other parrots. Cyanoramphus.
Food:
It has been recorded feeding on leaves, flowers, berries and seeds 14 plant species. Invertebrates are a minor component of the diet. The Reischek's Parakeet occasionally feed carcasses petreles and albatrosses, but not as often as Antipodes parakeet(Cyanoramphus unicolor). They feed on the floor often, including mud and feces accumulated within colonies antipodean penguin (Eudyptes sclateri) unoccupied, when penguins are away on their winter migration.
Distribution:
The Reischek's Parakeet is endemic of the Antipodes Islands. It is common in all the Antipodes Islands, particularly in more open areas and along shorelines close to penguin colonies.
Conservation:
โข According to the New Zealand Threat Classification System of 2008: Vulnerable.
โข Population trend: Stable.
โข Population size : 4000-6000 individuals.
The Reischek's Parakeet apparently they have a stable population, and are common within their distribution area of 2,000 has. They are protected by the isolated situation of the islands and their status Natural reserve strict. The greatest threat to long-term survival Reischek's Parakeet is the arrival of mammalian predators. In the winter of 2016 we attempted to eradicate the mice Antipodes Islands.
The species is also affected negatively by forestry operations: logging and burning have drastically reduced the available habitat, and selective logging can reduce the number of trees with suitable nesting holes and foraging opportunities..
It was hunted by Maori to feed, and previously it was persecuted because birds were damaging crops and orchards.
"Reischek's Parakeet" in captivity:
Son confident from the beginning and not at all shy. Usually they are ready to breed in captivity. Although they are ripe (about five months), It is best not to allow them to play in the first year.

The extinct Macquarie Parakeet(Cyanoramphus erythrotis) was a medium-sized green parrot. The head was bright green with pileum and a line in the eyes crimson red. The upperparts They were bright yellow-green to dark green with a scarlet stain on either side of the rump (usually they are hidden by the wings when resting), and a greenish-blue leading edge to the wings. The eyes They were yellow or red, and the bill It was black with a base Pearly. Both sexes looked similar, but the female It was smaller (Forshaw & Cooper 1981; Higgins 1999; Oliver 1955)
Taxonomic status:
This taxon is considered a subspecies of Cyanoramphus [novaezelandiae, erythrotis, subflavescens] (sensu lato) by some authors
Lives in "Perico de Macquarie":
The Macquarie Parakeet inhabited coastal grasslands tussock in the subantarctic Isla Macquarie (Forshaw & Cooper 1981; Taylor 1979).
Reproduction:
It is known nesting in grasslands without trees.
Food ยซPerico de Macquarieยป:
Little is known about the diet of the Macquarie Parakeet, but it is said that feed on crustaceans and other small invertebrates (Oliver 1955; Taylor 1979).
It was Earth (Forshaw & Cooper 1981) and it is said to have been foraged on the seashore, taking invertebrates fused cell algae on the beach (Oliver 1955; Taylor 1979).
Distribution ยซPerico de Macquarieยป:
The Macquarie Parakeet It was an endemic parrot Isla Macquarie, one sub-Antarctic island in the Antartic Ocean which is politically part of TasmaniaAustralia. The island and this species were discovered in 1810, time when this parakeet was still very common. The last sighting of the Perico de la Isla Macquarie was in 1891.
Conservation Cyanoramphus erythrotis:
โข Current category of the Red List of the UICN: EXTINCT.
Although hard Macquarie Parakeet They were adjusted well to inhospitable terrestrial environment Macquarie Island, They did not survive the predatory introduced species.
The extinction of the Macquarie Parakeet It was caused by the introduction of exotic predators, like cats, rabbits, mice and rats boat. He was also prey to rascรณn weka or the rascรณn of Lord Howe(Gallirallus australis). This robust flightless bird from New Zealand It was introduced on the island in the mid-nineteenth century as food for sealers, the same hunters killed large numbers of Macquarie's Parakeets (Macquarie Island) to feed. Unfortunately, the wekas They have caused considerable damage to endangered species, as they feed on small birds, Native insects and lizards.
The last sighting of live parrots occurred in 1891
Threat Reduction and Recovery
Translocation program may be suitable for the reintroduction of Norfolk Island Parakeet(Cyanoramphus cookii) on Isla Macquarie. Although programs have been tested for translocation failed Norfolk Island Parakeet(Garnett & Crowley 2000; Hermes et al. 1986), Similar programs have been successful for this parakeet in New Zealand. These programs have been successful with only 15 birds, Bottlenecks causing genetic programs with less than 150 birds. The low success of the pups in the breeding program New Zealand It may be the result of inbreeding depression or poor design of nests (Oritz-Cathedral & Brunton 2008).
The programs of eradication They are underway in Isla Macquarie. The cats were eradicated in 2002, the Keep(Gallirallus australis) in 1988 and is ongoing eradication program rats, rabbits and mice (Mouse muscle)(it. PWS 2009).

Cyanoramphus novaezelandiae cyanurus
(Salvadori 1891) – Of 29 cm approximately. More than the nominal, the plumage is more yellowish and the flight feather more intense blue.
The habitat of the Red-crowned parakeet includes native forest in the continental part of New Zealand, scrublands in some outlying islands and land with abundant grass in the Antipodes Islands.
The species, generally, most opted for the edges of forests and open areas to the Yellow-crowned parakeet, and the regions where the two species coexist, is, generally, at lower altitudes.
The birds tend to locate their calls when they fly over or through the forest canopy. They are most often in pairs; couples tend to remain together throughout the year. But, large groups gather where food sources are abundant at any time of the year. Where is fresh water scarce, groups of birds also tend to congregate to drink in springs or leaks.
In the Kermadec Islands, flocks are formed for bathing in tidal pools and rest on a branch (probably in other places also).
The Red-crowned parakeet they feed actively on in the early hours of the morning, they rest and groom themselves for much of the day, and is power again during the afternoon.
Reproduction:
The nesting takes place between October and March, with most laying between the months of October and December. Between two and ten (usually between five and nine) white eggs form the implementation. The eggs are deposited in a hollow of tree clad wood shavings, Although you can also have other places of sunset, including cracks in the rocks, burrows in the ground, etc, as well as a variety of nest liners including feathers, MOSS and grass.
The birds are territorial in the vicinity of the nest and can use the same site repeatedly. The incubation is carried out by the female and hard of 18 to 20 days. The pups remain in the nest during 5 to 6 weeks and the male will help with food, either through female or directly, one week after the emplumamiento.
In large litters some less developed pups can be seen. Adults undergo a post-breeding moult..
Food:
They feed on, both the canopy and soil, a wide range of vegetables, fruit, seeds, leaves, outbreaks, berries, flowers and nectar; they have priority for the seeds fallen during the autumn and winter. The species also feeds on invertebrates, honeydew and, in the Kermadec, even, algae and small macaws (Scutellastra kermadecensis).
Distribution:
The Red-crowned parakeet are in New Zealand and in a series of adjacent and outlying island groups.
Before European colonization, the species was extended by continent, but in the Decade of 1890 the population began to decline as a result of the destruction of their habitat and predation by introduced cats and mustelids.
The population is, undoubtedly superior to the 15.000 specimens, although decreasing due to habitat loss and predation.
The hybridization with the Yellow-crowned parakeet (Cyanoramphus auriceps) It is also a problem in some populations.
The subspecies chathamensis is threatened, with a population of less than 1.000 specimens.
The subspecies cyanurus is still relatively common with about 10.000 individuals in Macauley. There are at least 4.000-5.000 birds in the Group of the Antipodes Islands.

On the Mainland, the Yellow-crowned parakeet, they are mainly distributed among the lush native forests, mainly in the provided ecosystems of Nothofagus and Podocarpus, at an altitude of about 600 m. Although these birds are at much lower altitudes, the species tends to move at altitudes which are the Red-crowned parakeet, especially when their habitats overlap.
The Yellow-crowned parakeet they are more common in closed areas of scrub, less common in open spaces by which moves the Red-crowned parakeet.
It is more common on offshore islands, where predation by introduced mammals is reduced.
Birds are found more often in pairs or small groups, feeding in the middle or upper floor of forest or large shrubs. Although it is, generally, more arboreal than the Red-crowned parakeet, they tend to feed on land in the islands of the coast.
Reproduction:
The breeding habits they are similar to the of the Red-crowned parakeet, but these birds seem to be more territorial around the nest.
The Yellow-crowned parakeet They nest in tree holes.
The implementation is performed between the months of October to December but have been observed nesting in almost every month, presumably in response to food availability. Of five to nine eggs whites make up the implementation, with one incubation between 18 and 20 days. The calf is fed by the female who in turn receives food from the male., the young remain in the nest from five to six weeks.
Food:
The diet consists of plant material including outbreaks, berries, flowers and seeds, as well as invertebrates such as larvae, for example, Heliostibes vibratrix and mealybugs Ultracoelostoma assmile. The insects They seem to be more important in the diet of the Yellow-crowned parakeet that in the of the Red-crowned parakeet.
The species is also found in the chatham islands, where the Chatham Parakeet It has suffered from habitat loss, as well as competition and hybridization with the Red-crowned parakeet: both hybrids together with the Red-crowned parakeet, they survive better in open areas, helped by the improvement of the habitat and hybridisation control, so getting a slow recovery.
In the past the population of the Yellow-crowned parakeet has declined in number and the species is now rare throughout its range. As a result, is suspected to have one moderately low population. The world's population believed that it is inferior to the 5.000 specimens.
It is believed that this species has been adversely affected by the logging of forests, introduced predators, (cats, stoats and rats) and hybridization. Consequently, that you have been moderate declines in population to this day.
In the islands of the coast, the Red-crowned parakeet is usually much more common (Heather and Robertson 1997) and can be replaced by full to the Yellow-crowned parakeet in Solander Island. In Auckland Islands, There is an abnormally high rate of hybridization between the two species.
For its upbringing it is enough to have previous experience in the breeding of any of the smaller Australian parrots..
Reasonably hardy to cold, It has a thick plumage on their underparts which gives them a good insulation against the harsh winters; they withstand a cooler climate than most Australian species.
The sound of their voices is not strong or offensive and consists of pleasant chattering.
In terms of their longevity, according to sources, one specimen was still alive after 9.3 years in captivity
19 to 22 cm. length and a weight between 40 and 52 grams for males and between 30 and 41 grams for females.
The Malherbe's parakeet(Cyanoramphus malherbi) they are small bright green parakeets, equipped with a long tail and with a bluish green colour wash in belly and chest.
The wings they have the primary coverts and the edges to the primary external of azure-blue. The crown is lemon-yellow colour and the front band, it reaches the eyes, is orange, as well as two patches on each side of the rump.
The bill is bluish grey, with the tip of black. The eyes are red and the legs are brown.
The colors tend to have a brighter tone in the males.
The youth they are more opaque, especially the patch of front band and the crown, which may be absent. The tail It is short for several weeks after feather. The bill is a pale pink color that darkens gradually when the young bird matures. They have darker the eyes, a reddish brown tone.
The Malherbe's parakeet tends to be quiet and hard to see. A brief and loud chatter or a quieter soft contact call can denote its presence, but locating the bird can be extremely difficult. The Malherbe's parakeet often confused with the Yellow-crowned parakeet.
Even though have been recorded in subalpine bushes and thickets of Matagouri open zones (Discaria toumatou), the Malherbe's parakeet they are predominantly in the forest.
They usually feed in the canopy, but also under frequent places with low vegetation and soil.
Reproduction:
The Malherbe's parakeet can reproduce in every month, with a main breeding period between December and April; incubation peak is in January.
Clutch size media is of approximately 7 eggs, but register a wide range (range of 1 to 10). Egg laying is asynchronous with an interval between eggs of 2 days. The incubation lasts from 21 to 26 days, and the period of breeding ranges between 35 and 45 days.
The females They seem to choose the nesting sites, as well as carry out all the preparation, incubation and breeding, the male provides most of the food during incubation.
It is suspected that the female only feeds the chicks during the first 10-14 days, just as they do other species Cyanoramphus. Once past this period, both sexes take care, equally, feeding the pigeons.
There may be second clutches If there is enough food available, for example, during the sowing of beech, or if the first attempt failed. The female may lay a second clutch when first chicks have, approximately, 2 weeks of age. This leaves the male as the sole provider for both the chicks and the incubating female..
Second clutches are not uncommon; When is food plentiful, some couples can reproduce 3 or 4 times on.
The nests are accessed normally through holes in knots of branches and the main trunk of a tree.
They use all species of you have to build the nest, predominantly the Red beech (69% nests monitored in the continent, n = 138) and dead trees (20%).
Nests may have more than one meter of depth. Records placed nests in heights that range between 2,5 and 26 m.
Food:
The Malherbe's parakeet consume seeds, flowers, buds and small invertebrates (mealybugs and caterpillars). In a year of abundance of fruits, the seeds become the dominant element of their diet, and they seem to be the main food for young people.
Invertebrates seem to play an important role in the diet of this species of parakeet which for the Yellow-crowned parakeet.
Distribution:
Size of the area of distribution (reproduction / resident) 360 km2
To the Malherbe's parakeet les is in areas where the South beeches (Nothofagaceae), in forest valleys in the South Island, the valleys Hawdon and Poulter in the Arthur Pass National Park and the South Branch of the Hurunui Valley in Lake Sumner Forest Park. Are unevenly distributed within these valleys; absent in many parts, but in some other places can be quite common.
โข Current Red List of UICN: critically endangered
โข Population trend: Decreasing
This species is the smallest of the class Cyanoramphus along with the Yellow-crowned parakeet.
The Malherbe's parakeet It is the kind of rare parrots of New Zealand. The population was wiped out by rats and stoats introduced by men.
Also the changes in the habitat due to the ungulates and opossums they have affected the species.
Some diseases have been discovered in two of the areas in which live.
It is in progress conservation actions such as the predator control in the three valleys of the continent and the protection of the trees hosting the nests.
The captive breeding programs they have helped to release the birds in 4 Islands cleared of predators. This work is still in progress.
On the Mainland, all populations are monitored closely by the Department of conservation.
The total population It was estimated in 290/690 individuals at the beginning of 2013.
The continent has between 130 and 270 specimens and Islands surrounding between 160 and 420.
"Malherbe's parakeet" in captivity:
Usually they are not in captivity.
A small captive breeding program was established in 2003.

The Antipodes parakeet(Cyanoramphus unicolor) has a plumage brighter yellowish green, more yellowish on the hand down and sometimes with irregular yellow markings at the top. It is the only species that does not have color markings on head and tail. It is the largest of its kind.
The face and top are bright emerald green, and the contrast with the neck and the chest is more off.
At the top of the wings, the outer bands of the flight feather are blue, While the long tail It is green with fine yellow piping.
The great bill is silver-grey with dark end. The eyes are orange-red. The legs and feet are greyish.
Both sexes are identical. The female is slightly smaller than the male.
The young birds they are of tail shorter. The young people have the bill Pink White and the eyes light brown.
Habitat:
The Antipodes parakeet, usually, they prefer areas with tall grass (POA littorosa), areas of open scrub and sedges (Carex). Can also be seen in areas where thorny ferns grow (Polystichum vestitum) and the bushes (Coprosma antipode).
The birds are most common on steeper slopes and near water courses, alone or in small groups; They walk on the floor and climb among the branches as they seek food, normally during the morning and before nightfall.
These birds are very Meek and curious. When frightened, they disappear among the dense vegetation, keeping silent or giving a short alarm call. More than half of the day is spent sunbathing and grooming in protected areas. They bathe in small ponds and rest in burrows.
Reproduction:
The season of reproduction takes place between October and March. The Antipodes parakeetnest in soils with good drainage, a length of at least one meter. The nests is carved in fibrous peat, under the thick base of the tall grass vegetation. The nesting Chamber It is full of rootlets or fern scales.
The spawning occurs between November and January. The female lays 2-3 white eggs (5-6 in captivity). She carries out most of the duties of nesting, and incubates the eggs for a few 26 days. She cares for and feeds the chicks for nearly two weeks. The male contributes to breeding, feeding the female during this period, as well as feeding the young until their independence, at least two weeks after leaving the nest.
Food:
The diet main consists of leaves; an amount of crushed leaves, still attached to the plant, they are a distinctive sign of the power of the Antipodes parakeet. Also consume seeds, berries, the remains of penguins and petrels dead. They often enter into colonies of the Rockhopper Penguin (Eudyptes chrysocome) and of the Sclater's Penguin (Eudyptes sclateri) between the months of October and may, to feed on their eggs or dead young. It also feeds on the eggs and sometimes on the newborns of the same species.. (The sympatrico Red-crowned parakeet prevents competition by taking advantage of the niche that provide seeds, flowers, berries and small invertebrates.)
Distribution:
Endemic to the main island Antipodes, In addition to Bollons, Leeward, Inner Windward and Islands Archway.
The world's population of the Antipodes parakeet It is estimated between 2.000 and 3,000 specimens. Although common and stable within its range, the species is permanently at risk due to accidental introduction of predators, problem that could be fixed in no time.
Some birds are kept in captivity in New Zealand.
VULNERABLE.
"Antipodes parakeet" in captivity:
This stocky parakeet can live in community with species with similar characteristics.. It is usually outgoing, Active and depending on their way of breeding (natural or hand) and earlier experiences, It may be a trusted Parrot (hand raised or treated early), even being raised by their parents tends to be entrusted.
As a pet it could be good pet by his way of being cheerful and curious.
It is a rather nice parrot as vocalizations. It is not just loud. He likes to climb, There is no great need to crack and loves to be on the floor. enjoy the baths.
However, due to their vulnerability, is very rare poultry.
