Kaka - photographer: Peter CrawThe North Island kākā is a large forest parrot, mainly olive brown, with a dark crimson collar, crimson under-wings with dark edged feathers and crimson rump.  

Kākā prefer to eat seeds, fruit, nectar and insects, sometimes tapping the sap from the bark of beech, mountain tōtara, and southern rātā.  Their powerful beak allows them to rip bark off trees and their delicate brush tipped tongue is used to take nectar from flowers.

The kākā is a cavity breeder and makes its nest in a shallow bowl in hollow branches and trunks of old or dying trees. Eggs are laid between September and January and incubated only by the female for about 24 days. The chicks fledge at about 60-70 days old, remaining with the parents for a further five months. The male's role during this breeding period is to feed the female on the nest and to help with caring for the chicks.

The kākā has a variety of calls, the main one, uttered in flight, is a loud bell-like call, often a single note but sometimes repeated several times.  They can screech and make other chatty parrot-like calls.

Kaka in Kowhai - photography by Dr Kerry RodgersKākā have not been released on Tiritiri Matangi and neither have they bred there - yet. The occasional sightings are becoming more frequent. The nearest large population is on little Barrier Island/Hauturu, from where they have spread to breed at Tawharanui Regional Park.
