The '''Macquarie Parakeetparakeet''' ('''''Cyanoramphus erythrotis'''''), also known as the '''Macquarie Island Parakeetparakeet''', is an extinct parrot from [[Macquarie Islandsubantarctic]], a subantarctic island in the [[SouthernMacquarie OceanIsland]], that isan politicallyoutlying part of [[Tasmania]], [[Australia]], in the [[Southern Ocean]].

The Macquarie Parakeetparakeet was previously considered to be a subspecies of the [[Redred-fronted Parakeetparakeet]] ''C. novaezelandiae'', which it resembled in appearance, but was later lumped with [[Reischek's Parakeetparakeet]] from the [[Antipodes Islands]] in a 2001 paper by Wee Ming Boon and others following an examination of the molecular systematics of the genus which found that many of the Redred-crowned Parakeetparakeet subspecies should be elevated to full species.<ref name=Boon2001>Boon, Wee Ming; Kearvell, Jonathan C.; Daugherty, Charles H.; & Chambers, Geoffrey K.

The transition from abundance to extinction took little more than a decade. The critical events leading to the extinction of the parrot were the introductions of both [[Wekaweka]]s and [[European Rabbitrabbit]]s to the island in the 1870s and their subsequent spread during the 1880s. Until then winter, with the seasonal absence of [[burrow]]-[[nest]]ing [[petrel]]s and breeding [[penguin]]s, was a period of food scarcity for [[Terrestrial animal|terrestrial]] [[predation|predator]]s, which served to keep their numbers low. The presence of rabbits provided a year-round food supply for cats and wekas and allowed their numbers to expand, leading to increased predation on the parrot, the last sighting of which was in 1891.<ref name=Taylor1979/>
