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

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 noon, They lie between the foliage of the trees.

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

In some areas, the New Zealand Kaka they are sedentary. However, most of the times are erratic or 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 couple sometimes extends with its beak entry hole.

The spawning contains 4 or 5 eggs White. These are deposited on a layer of sawdust covering the lower part of the cavity.

The incubation, that lasts a few 24 days, It is performed only by the female. She leaves the nest at dawn and dusk to be able to be powered by your partner. A wizard, sometimes, You can participate in the feeding of the female during the period in which incubates.

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

The young 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 rare time 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 populations of opossums are scattered, the New Zealand Kaka they spend nearly the 60% of their time feeding on flowers and berries. In addition, consume sprouts, seeds, nectar and SAP.

Distribution:

Tamaño del área de distribución (reproducción/residente): 71.100 km2

This species is endemic of New Zealand.

Distribution of subspecies
Conservation:

• Current red list of UICN: Danger

• Population trend: Decreasing

This species has a very irregular distribution. In the majority of places, is rather sparse, but in other places, It is common at local level, especially in some coastal islands.

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

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.

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 informó que los New Zealand Kaka can reproduce a partir de los 7 years of age in captivity.
