The Red-crowned Parakeet (Cyanoramphus novaezelandiae) is a species of bird native to New Zealand. It was once widespread across the islands and mainland of New Zealand. During the latter half of the 1800s it was extremely abundant. It is now extinct on the mainland of New Zealand and is confined to Stewart Island, Kapiti and Matiu/Somes Island, the Auckland Islands, Chatham Islands, and a few other offshore islands. The mainland extinction was due to introduction of other species, mostly stoats, rats and possums. The species is considered Vulnerable by the IUCN and Bird Life International.
The diet of the Red-crowned Parakeet consists of seeds, fruit, berries, nuts and other plant matter. It is a common bird in aviculture and is easy to breed. It exists in various color mutations including, yellow, cinnamon and piebald.
This species should not be confused with the Red-crowned Parakeet (Pyrrhura roseifrons) of South America.
