The North Island kōkako (Callaeas wilsoni) 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 (although this colour develops with age: in the young of this bird they are actually coloured a light pink). Because of its wattle, the bird is sometimes locally called the blue-wattled crow, although it is not a corvid.
