Perruche des Antipodes

Cyanoramphus unicolor

Perruche entièrement verte endémique des îles subantarctiques des Antipodes. La plus grande des perruches indigènes de Nouvelle-Zélande. Les mâles sont plus grands que les femelles. Commune dans tout son habitat et son aire de répartition, elle marche et grimpe à travers la végétation lorsqu'elle fourrage. Elle charogne des carcasses d'oiseaux. Un oiseau curieux, s'approchant souvent des visiteurs humains. Son cri est un bavardage profond et distinctif « kok-kok-kok-kok ». Partage son aire de répartition avec la Perruche de Reischek, mais s'en distingue par sa taille beaucoup plus grande et l'absence de calotte rouge.

The Antipodes parakeet also live on the 0.1 square kilometre Archway Island as well.

Comportement

These parakeets eat leaves, buds, grass, and tussock stalks, as well as sometimes feeding on seeds and flowers, and will scavenge dead seabirds. The Antipodes parakeet also preys on grey-backed storm petrels, entering burrows to kill incubating adults, even digging at the entrance if it is too small.<p>Antipodes parakeets spend much of their time on the ground and in very small groups, in pairs or solitary.<p>They are quite inquisitive, territorial, probing and mischievous.<p>Their nest is in a tunnel 2 metres beneath the fibrous peat away from the wind.
