 New Zealand pigeon, kererū

The kererū is the largest pigeon in New Zealand and the fifth largest in the world. The head, throat, upper breast and upperparts are a metallic green with a purplish sheen. The upper breast is shaped like a baby's bib and clearly stands out against the pristine white of the lower breast and underparts. The bill is crimson with an orange tip and both the eye and feet are crimson. The call is a soft penetrating 'kuu'.

Kererū are herbivorous, and although they will eat foliage and flowers, they love to eat fruit. The favoured fruits are miro, pigeonwood, pūriri, taraire, and tawa, but coprosma, elder, hangehange, kahikatea, karaka, nīkau, and tītoki are also eaten. Their love of fruit is a clue to their ancestry. Although they are often referred to a 'wood pigeons', this is a misnomer which originates in their superficial resemblance, in size and shape, to European woodpigeons. In fact they are more closely related to the fruit doves of Australia. They perform an important ecological function in native forests, because they are the only birds that can swallow whole the large seeds of trees such as taraire and karaka.

Breeding takes place between September and February and is timed to coincide with certain fruits being available. The nest is a flimsy affair, often a precariously balanced platform of sticks on a horizontal fork. Often the egg or chick can be seen from the ground through the nest. Both adults incubate for about 30 days and the young kererū fledge at between 30 and 45 days old.

There was no need to introduce kererū to Tiritiri Matangi because they fly easily and frequently between the Island and the mainland. As the forest on the Island has matured, they have been seen in increasing numbers, and are often to be seen resting on a pūriri branch after gorging themselves on the fruit.
