Macquarie Parakeet - Cyanoramphus erythrotis


Description Perico Macquarie:

27 cm.. length

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 appeared 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

Perico habitat 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 Tito Macquarie:

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 Tito Macquarie:

The Macquarie Parakeet It was an endemic parrot Isla Macquarie, one sub-Antarctic island in the Antartic Ocean It is politically part of Tasmania Australia. The island and this species were discovered in 1810, time when this was still very common parakeet. The last sighting of Perico Isla Macquarie was in 1891.

Conservation Macquarie Parakeet:

• Current red list category 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 rascón weka or the rascón 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 a large number of Perico Macquarie (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 parakeets 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 young in the 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).
