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 appeared similar, but the female It was smaller.
This taxon is considered a subspecies of Cyanoramphus [novaezelandiae or subflavescens] (sensu lato) by some authors.
The Lord Howe Island Parakeet It was occasionally observed in flocks. There is little information on their habitats, probably they lived in forests inhabited and cultivated areas Lord Howe Island. No information on the use of different habitats for different activities.
Nothing is known of sexual maturity, life expectancy and natural mortality of this extinct species. However, It has been estimated that the life of Lord Howe Island Parakeet It should be similar to that of 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 it is said that the captive birds are reproduced when they were under one year old.
Little else is known about breeding Lord Howe Island Parakeet, probably they reproduced in response to climatic conditions and food availability, nesting in tree holes or hollow pipes, in crevices between rocks or cliffs.
Meal Lord Howe Island Parakeet probably it consisted of plant material, as seeds, fruit, buds and leaves of native trees and shrubs. Other existing populations mainly ate seeds, fruits and berries, egg yolks, sprouts and flowers, as well as, occasionally, a small number of invertebrates.
• The last record we have of this species dating 1869. EXTINCT.
The population declines were mainly due to habitat modification, hunting, poisoning, and the introduction of predators (especially cats and rats).
However, 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, and it is destroying crops and orchards of the inhabitants of the island.
