The Kōkako (Callaeas cinerea) is a forest bir which is endemic to New Zealand. It is slate-grey with a black mask and wattles. It is one of three New Zealand wattlebirds, the other two being the endangered Tieke (saddleback) and the extinct Huia. Previously widespread, the birds were decimated by the introduction of exotic predators such as possums, stoats, cats, rats and mice. There were two sub-species of Kōkako, although one of these may now be extinct.
