Numbers of Kōkako increase in Bay of Plenty

The North Island kōkako has seen increasing numbers due to concerted, long-term predator control in the Bay of Plenty. The kōkako is an endangered forest bird which is endemic to the North Island of New Zealand. It is grey in colour, with a small black mask. It has blue wattles. Because of its wattle, the bird is sometimes locally called the blue-wattled crow, although it is not a corvid.
