Habitat of "Kea":

The Kea (Nestor notabilis) they live at an altitude between 600-2400 m.

They are commonly found near tourist attractions. But, its main habitat is in the tree line between 950 and 1.400 m.

They mark a certain preference for deep canyons whose walls are covered in forests of beeches (Nothofagus cliffortioides). At higher altitudes, that is it can be observed in subalpine Shrublands. The species It is considered as monotype.

It is a bird family and curious. He likes to live close to the houses and feel the human presence. His mischievous behavior and his sharp intelligence earned him the title of ยซclown of the mountainsยซ.

It's a joy for tourists, that compensates for, in part, the wrong bad reputation that had in the past.

During the period of nesting, the pair is the basic social unit, but for the rest of the year, It is a species very gregarious they live in family groups, feeding in flocks of 30-40 birds, often in landfill sites.

The males are polygamous, each can have a harem of some 4 females. Dominant males are not necessarily the oldest.

Establishing a hierarchy is tricky. Adults often dominate subadults but it can also happen that a young dominates an adult.

The Kea established territories that are resizable. These can be overlaid on the periphery, but the nucleus or the central part situated, near the nest, It has an inviolable space that is defended with aggression.

During the nesting season, breeding birds are sedentary, and never will they move away to more than one kilometre from the nest. On the other hand, the non-breeding birds are very mobile, and some have been seen more of 60 km of where they were ringed.

Reproduction of "Kea":

The strong conjugal bonds and fidelity to the nesting site are the two basic rules of the Kea, that is manifested by the fact that the nest often takes several years to be completed. But, unpaired males can visit the nests and try to mesh with females.

The breeding season extends July-January. The female lays 2 to 4 white eggs in a burrow or cavity covered with some sticks, leaves and MOSS. The site is often found at the base of a cornice, but they also use stone blocks placed above the tree line.

The eggs are deposited a few days apart and only the female incubates for a period that varies between 21 and 28 days. In the meantime, the male stands guard nearby and is responsible for feeding his partner. Initially, bring enough food to also supply the calf, but after a few weeks, the female leaves the nest, in order to help you in your task.

The chicks, covered with a white marker, they leave the nest after 13 to 14 weeks. They continue to be fed by the parents during 1 month to 6 weeks. In January and February, immediately after the nesting season, the Kea they tend to congregate in large flocks which can contain 50 or more individuals.

Food of "Kea":

During the summer, the Kea they can be active even during the night. In winter they are reduced to more modest altitudes below the elevation of snow. Some groups choose to stay in the mountains near ski resorts.

The Kea feed of carrion, in particular sheep. Contrary to its reputation, they never attack healthy sheep. have a diet mainly vegetarian and they fed both in trees and on the ground. Your menu includes leaves, outbreaks, estate, seeds, berries, flowers, nectar and insects. In summer they also eat beetles, worms, lobsters and land snails.

The dominant males they are known to find its food in campsites and parking areas.

Distribution:

Size of the area of distribution (reproduction / resident): 63.300 km2

endemic to the South Island of New Zealand (Although vagrants have been recorded in the North Island, for example, in the Tararua mountains), finding, mainly, between 950 m and 1.400 m above sea level in forests and subalpine scrub.

Its distribution extends from the South West of Southland (for example Wilmot Pass), to the North by the Fiordland National Park (for example, about Te Anau, Homer Tunnel), Westland district and The Southern Alps (for example, Westland National Park, Fox and glaciers Franz Josef, Aoraki/Mount Cook National Park), Arthur Pass National Park and Graigieburn Forest Park. Nelson Lakes National Park and Big Bush State Forest, the Seaward Kaikoura Range (for example, the Mount Manakau), the region of Marlborough, the Richmond range, finally reaching the Highlands around Mount Cobb, at its Northwest end.

Conservation:


Vulnerable

โ€ข Current Red List of UICN: Vulnerable

โ€ข Population trend: Decreasing

The populations of the Kea they appear as stable and they can range between 1000 and 5000 specimens.

The concentration of birds around tourist spots leaves a false impression, giving the impression of being a fairly ordinary parakeet.

Due to the false reputation he had for attacking sheep, This bird was hunted by farmers and thousands of birds were exterminated between 1860 and 1970.

Since 1988, the Kea is fully protected, What does not prevent, sometimes, their capture and sale as a pet.

The "Kea" parrot in captivity:

Very rare in captivity.

As indicated sources, a captive male for Kea was still alive after 47 years in the Antwerp Zoo. It showed signs of old age. Other Kea in the bristol zoo, of at least, 43 years of age showed no signs of aging.

In captivity, These birds can be raised from the 4 years of age

Description

45 cm.. length and an average weight of 550 g..

The New Zealand Kaka (Nestor meridionalis) they are some great parrots with a tail of medium length and a plumage predominantly Brown and Red.

The adult male has the crown whitish grey color and the neck with a greyish Brown appearance due to large brown feathers that surround you.

The under eye and the sides of the neck has a bluish grey clear. The lores are greyish Brown, that contrast with the ear-coverts strongly tinged with orange. The sides of the chin they have reddish-brown infiltrations.

The feathers of the upperparts are greenish Brown with darker stripes and stripes. Those in the back of the neck They are crimson red with yellow endings and browner bases..

The the mantle, sometimes, has some red spots. Rump and uppertail-coverts are red with dark brown trim. The lower area of the wings and axillary they are also red.

The feathers of the chest are olive brown in colour with reddish edges subterminales. Belly and undertail-coverts are red with dark edges.

The tail is brown with lighter tip.

The bill is brownish grey, more powerful that the of the Kea. The cere Brown it is decorated with a few whiskers. The irises is dark brown, legs dark gray.

The adult female presents a bill shorter and one mandible less curved top.

The youth they are similar to adults, but have a small yellow spot at the base of the lower jaw.

Subspecies description

  • Nestor meridionalis meridionalis (Gmelin, 1788) – Nominal species

  • Nestor meridionalis septentrionalis (Lorenz von Liburnau, L 1896) – It measures 42 cm approximately. Variation of the nominal (Nestor Meridionalis). More small, in general, and plumage more off. The red band of the neck is more small and dark. The back of the wings olive color is more dark.

Habitat:

The New Zealand Kaka (Nestor meridionalis) they frequent the compact forests of low to medium height, where there are mainly podocarp and beech trees of the genus Nothofagus. Occasionally they come into gardens and orchards, especially in winter.

These birds they tend to live at altitudes between 450 and 850 meters in the summer and from the sea level to the 550 meters in winter. But, from time to time, You can climb up to the 1.500 m.

The New Zealand Kaka they live in pairs or in small groups of up to ten birds.

These birds are not as well known as the Kea (Nestor notabilis), Although in some places come to feed in the hand of the tourists.

We can often see them at the top of trees or simply flying over the canopy.

The birds that are found in the air almost always heard before to be seen.

The New Zealand Kaka they are active during the morning and afternoon. At the hottest time of the day, around midday, They lie between the foliage of the trees.

Around the darkness, they perform a series of acrobatic flights, before returning to their roosts. Screams and calls can be heard well into the night.

In some areas, the New Zealand Kaka they are sedentary. But, most of the time they are erratic or perform short altitudinal migrations. These birds are able to fly long distances. They fly to vigorous banging of wings.

Reproduction:

The season of nesting is from September to March, but it is above all active between November and January.

The nest is located in a tree cavity between 3 and 9 meters above the ground. The pair sometimes enlarges the entrance hole with its beak..

The spawning contains 4 or 5 eggs white. These are deposited on a layer of sawdust that covers the bottom of the cavity.

The incubation, that lasts a few 24 days, It is done solely for the female. She leaves the nest at dawn and dusk to be able to be powered by your partner. an assistant, sometimes, can participate in the feeding of the female during the period in which she incubates.

In the North, the young have white down, While the of the South they have grey down at the bottom.

The juveniles they acquire their full plumage in ten weeks.

For the duration of the stay in the nest, they are fed by both parents.

The breeding success rate is relatively low and they rarely lay more than one egg per year..

Food:

The New Zealand Kaka It has a long tongue terminated tip, What helps you to extract nectar from the flowers and to collect molasses.

In the Spring, in the South of the island, the New Zealand Kaka almost passes the 30% of their time in the trees (Beech) where feeding of honeydew produced by the local cochineal (Ultracoelostoma assimilates). In other stations, This food is a less important resource due to competition with the WaSP, which is also a great consumer.

The larvae of beetles of long antennae they are also a good source of nutrition.

Throughout the year the New Zealand Kaka, regularly, frequent trees, where it used its powerful curved beak to hunt insects hidden beneath the bark.

When opossum populations disperse, the New Zealand Kaka they spend nearly the 60% of their time feeding on flowers and berries. It also, consume sprouts, seeds, nectar and SAP.

Distribution:

Size of the area of distribution (reproduction / resident): 71.100 km2

This species is endemic of New Zealand.

Subspecies distribution

Conservation:


Endangered

โ€ข Current Red List of UICN: Danger

โ€ข Population trend: Decreasing

This species has a very irregular distribution. in most places, is rather sparse, but in other places, is common locally, especially in some coastal islands.

Its population It is estimated between 3750 and 15,000 specimens.

The main threat is the habitat degradation. It stays within primary forest fragments, showing its very low adaptation to artificial habitats.

The New Zealand Kaka not nest every year in a systematic way. When I was try to reproduce in captivity, the success rate was not very high (on average the 56% eggs not hatched ).

Clutches often suffer from the predation on the part of the weasels It was introduced on the island. For all these reasons that the species is classified as VULNERABLE.

"New Zealand Kaka" in captivity:

Very rare in captivity.

In terms of their longevity, according to sources, a specimen in captivity lived during 15 years.

Taking into account the longevity of the similar species, the maximum longevity of these birds might be underestimated. Other sources indicate that these birds can live up to the 35,5 years in captivity, something that is plausible, pero que no ha sido verificado; el mismo estudio informรณ que los New Zealand Kaka can reproduce a partir de los 7 years of age in captivity.

Norfolk Island Kaka

Content

Description:

The Norfolk Island Kaka (Nestor productus) was their large with a bill, wings short and wide, and with legs and feet large.

Norfolk Island Kaka

I had 38 centimeters long. The top of his head era gris pardusca, while its face varied from yellow to orange, sometimes with a reddish tint. It was said that his Hip It was greenish yellow, and upperparts, including the wings, they were mostly greyish-brown in color, slightly darker than the top of the head, with the bottom of the back and rump orange or dark red and the tail brown. Upper chest It was brown and gray bottom bright yellow, with the belly and sides reddish orange (Forshaw & Cooper 1981, 2002; Greenway 1958).

Its social structure and dispersion are not registered, but the Norfolk Island Kaka of New Zealand, he watched alone or in small groups of up 10 individuals (Higgins 1999).

Habitat:

Habit in the native forest in the Norfolk Island and about Phillip Island (Greenway 1958). The species could be observed both in the canopy of tall trees, and soil, the rocks (Gould, 1865, Greenway 1958).

Given its endemism in the Norfolk Island, the Norfolk Island Kaka It was presumably sedentary.

Reproduction:

Little is known of reproductive cycle of the Norfolk Island Kaka; just put on record of four eggs in tree holes (Gould 1865).

Food:

It is known that he fed on nectar Flowers tree white wood (Lagunaria) (Gould 1865). Definitely should be more varied. The captive birds they ate lettuce and the leaves of other vegetables, as well as dairy meals and fruit juice (Gould 1865). Presumably he foraged in both the soil and the canopy (Gould, 1865).

Distribution:

Its range was about 15,5 hectares.

It was endemic to the Norfolk island (in Australia) and nearby Phillip Island, Australia. It became extinct in the wild in mid-century 19 on Norfolk Island, and possibly a little later Phillip Island.

The species is believed to have had a very limited ability to move between islands., and probably he spent his whole life on the island of his birth (Gould, 1865).
In the Norfolk Island Kaka occasionally kept in captivity, as the birds were gentle and easy to capture alive (Gould 1865). The species He survived in captivity until after it had become extinct in the wild (Greenway 1958). There are no known captive populations and none has been reintroduced into the wild. The last known living bird was in captivity in London in 1851 (Garnett et to the., 2011).

No made extensive studies for this species. But, there have been a series of ornithological studies in the Norfolk Island since the species disappeared from the island (p.ej. Bell 1990, Robinson 1988, Schodde et al., 1983, Smithers y Disney 1969), no signs have been found of the species.

Conservation:

โ€ข Current category of the Red List of the UICN: extinct.

Rationale for the Red List category

This species was known in the Norfolk Island, but it was Extinguished to mid 1800. It is believed that the elimination of habitat and hunting have been the main drivers.

According to reports, was tame and, Therefore, hunted strongly convicts and early settlers and easily trapped as a pet.

No information is available on the population size before its decline.

"Norfolk Island Kaka" in captivity:

They were captured by his meekness and they were common in the Norfolk Island
