Anatomy-parrots

Description:

26 cm.. length and 100 g. of weight.

The upperparts of the New Caledonian Parakeet (Cyanoramphus saisseti) they are mostly green, with some bluish green in the tail, violet-blue along the outerweb flight feathers, and red patches on each side of the rump. The underparts are yellowish green, yellower near throat, and gray below tail (Forshaw 1989, Juniper & Parr 1998, Doughty et al. 1999).

A red patch extends from the crown up to the forecrown, and it extends in a narrow band from the forecrown up to the ears (Juniper & Parr 1998).
The bill is leaden gray, with black tips, the irises is red-orange and legs are dark gray. (Layard & Layard 1882b, Juniper & Parr 1998).

The males typically exceed the females in size, although its plumage is similar (Verreaux & walls 1860, Layard & Layard 1882b, Salvadori 1891, Forshaw 1989)

taxonomy:

In the past it was considered to New Caledonian Parakeet conspecific of Red-crowned parakeet (Cyanoramphus novaezelandiae) of New Zealand, but genetic studies have shown that it is a separate species and occupying a basal position on gender Cyanoramphus, which indicates that the genus would have its origin in New Caledonia.

Habitat:

New Caledonian Parakeet

The New Caledonian Parakeet They were primarily fed at low altitudes canopy, and regularly they observed on the edge of the forest, on slopes or in the forest maquis (scrub).

Seem to have small populations and their distributions are expected to shrink as a result of climate change.
They are not particularly shy, although they tend to be rather calm and difficult to observe.

Reproduction:

It has been reported that the nesting It occurs between November and January, and nidadas They consist of two to five eggs, that they are placed in holes in trees (Hannecart & Lรฉtocart 1980, Theuerkauf et al. 2009b).
Genetic evidence suggests that the species is polyandrous, and the presence of male food assistants suggests that probably involves mating system poliandria cooperative (Theuerkauf et al., 1999).

Food:

It is usually fed in average heights, low canopy, but it has also been observed that feeds on the floor.
Essentially it is granivore. It feeds mainly on seeds and fruits, besides berries, nuts and other plant parts (outbreaks, flowers and leaves).

Distribution:

The New Caledonian Parakeet It is endemic to the main island of New Caledonia, although there are still uncertainties about the extent of its range and population size (Taylor 1985, Juniper & Parr 1998). The species was considered rare at the time of its introduction (Verreaux & walls 1860). But, in the decade of 1880, Flocks of birds were reported in the West, flying into the valleys Moindou from nearby mountain forests, where it is rumored to have slept in large quantities (Layard & Layard 1882b).

It has the lowest population density of parrots New Caledonia.

Conservation:


Vulnerable


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

โ€ข Population trend: Decreasing.

โ€ข Population size : 2500-10,000 individuals.

The New Caledonian Parakeet They face a variety of threats, and their populations seem to be in decline. But, it is difficult to determine the cause or extent of their declines due to the paucity of ecological data.

classified as Vulnerable because it has a single small population suspected to be declining due to predation by invasive species; his fortress is in an area threatened by nickel mining and may be in rapid decline in the near future.
The humid mountain forest is not threatened, but it is possible that this species in need of other habitats, some of which, particularly semi-deciduous forests lowland, They have almost disappeared from the island. It is possible that introduced diseases (such as avian malaria) or the mammals (especially rats) It has been a cause of decline.

There is no evidence that nest poaching is widespread.

Habitat:

Azure-rumped parrot

It is distributed mainly in lowland and lower montane forests, next to forests, and from time to time in the plantations or rice fields until 800 m altitude (less common in coastal habitats).

The birds are usually found in pairs or in small groups and may be quite accessible. They can be harmful to the crops, especially corn crops, and they are often active at night.

Reproduction:

Little is known of the species reproductive cycle, but a condition of being reproductive female was observed in April and birds have been investigating possible nests in September. In Sulawesi during November were observed in several nests chicks.

Food:

The diet includes fruits, seeds, nuts and berries.

Distribution:

The Mรผller's Parrot is distributed throughout the Celebes island e close Islands, including Button and Tobea in the South-East, groups Togian and Banggai the east, and Talisei, Bangka and Manadotua in the North, extending northward through the Sangir group, at least in Karakelong in the Talaud group.

In Philippines, the species going from the Sulu archipelago, in the South-West, including at least Bongao, Sanga Sanga, Sibutu, Tawitawi, Jolo, Loran and Basbas.

Also distributed in the main islands of Philippines Luzon, Samar, Leyte, Surigao del Sur, Blacks, and Mindanao, as well as the Polillo Islands, but it is very rare in the country.

Elsewhere widespread and locally common, While the capture and loss of habitat have caused declines in some areas. Apparently less common than Blue-naped Parrot, which cohabit.
