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.
As of 2010, North Island kōkako were present in Pureora Forest Park, Whirinaki Te Pua-a-Tāne Conservation Park, Mapara Wildlife Reserve, the Hunua Ranges, Ngapukeriki, Kaharoa Forest, the Te Urewera National Park, Puketi Forest, the Waitākere Ranges and the Waima/Waipoua Forests of Northland. Kōkako can be seen relatively easily on a number of publicly accessible offshore island sanctuaries, including Tiritiri Matangi and Kapiti Island where the regenerating forest is low enough to provide close views. A captive bird can be seen at Pukaha / Mount Bruce National Wildlife Centre.
