Kakariki - photographer: Simon FordhamThe Red-crowned parakeet, commonly known by its Maori name kākāriki, is a long tailed bright green parrot with a red crown and forehead and a band of red which extends from the bill through the eye and beyond. It has crimson rump patches and bright blue on its wing coverts and some outer flight feathers.

Kākāriki have a rapid, direct flight, usually above the canopy and often accompanied by a rapid loud chatter: "ki-ki-ki-ki-ki". When feeding they may babble, or else are silent.

Kākāriki are very rare in the North Island, though this wasn't always the case. They were common in the 1880s but introduced predators such as feral cats, stoats and ship rats decimated the population. They are even rarer on the South Island, but are widespread on Stewart Island and many predator-free island reserves, including Tiritiri Matangi.  

Kākāriki eat a wide variety of plant seeds (particularly flax), fruit, berries, buds, shoots and flowers, as well as nectar and small invertebrates. They often feed on the ground rather than in the canopy, making them susceptible to mammalian predators.

Kakariki - photographer: Peter CrawRed-crowned parakeets make their nests in holes in branches and trunks, or at ground level, usually amongst dense vegetation. Occasionally they interbreed with the yellow-crowned parakeet, another sub-species even rarer than the red-crowned parakeet. They live in pairs, male and female staying together all year round, and often joining other pairs and their young. In the autumn and winter they form small flocks. They are non-migratory, though they are capable of flying long distances, usually when searching for food or fresh water. Kākāriki from Tiritiri Matangi have flown to the Shakespear Regional Park on the tip of the Whangaparaoa Peninsula, a distance of about four kilometres, and have established a breeding population there. 

The red-crowned parakeet was the first bird to be introduced to Tiritiri Matangi. Soon after the Island became part of the Hauraki Gulf Maritime Park in 1971, permits were obtained for the Wildlife Service to release kākāriki on Cuvier Island and Tiritiri Matangi. About thirty captive-reared birds were flown from Mount Bruce National Wildlife Centre to Ardmore Airport in South Auckland. The Cuvier-bound birds were then driven to Whitianga, but the boat that was to have taken them to Cuvier was not there, so they were driven back to Auckland. Unfortunately some birds died on this hot and stressful journey. After a few days in an aviary to recover, the survivors were released on Tiritiri Matangi. This was in January 1974, 10 years before planting started. It was a small article in the NZ Herald reporting the kākāriki release that prompted John Craig to investigate the Island as a place to do research. More kākāriki were released in 1975 and ’76.

Although there is now a thriving population on the Island, some of them lose a lot of feathers at certain times of the year, especially in the spring. There has been speculation about whether this is caused by mites, by a condition called 'beak and feather disease', or simply by a pre-breeding moult. During 2011-13, this problem has been investigated as part of a PhD project.
