Areale e habitat

Yellow-crowned parakeets prefer the upper canopies of tall, unbroken stub and forest, though they have been observed at high-altitude tussock meadows and on some of the subantarctic islands. A notably favoured habitat is mixed podocarp/nothofagus forest.The preference of C. auriceps for the upper canopies may have placed it at an advantage in comparison to the red-crowned parakeet, as it likely reduced the risk from predators.<p>These parakeets are endemic to New Zealand and range across the main islands, as well as Ewing Island in the Auckland Islands. This is the world's most southern observed location of Cyanoramphus, and the second-southernmost location of living parrots.
