The distribution of the North Island Kokako (Callaeas cinerea wilsoni) in the western King Country and Taranaki was recorded during summer 1980-1981. The survey confirmed that the Kokako was widespread in the study area but showed that its range is continuing to shrink. The status of many populations is still uncertain. Kokako appear to have disappeared recently from large forest tracts in south-eastern and inland Taranaki and from large isolated forests in the north. Within large forest tracts Kokako were not recorded in some locations where they had been present before 1970. Most Kokako were in unmodified rimu-tawa dominant forest and habitat deterioration appears to be an important factor in their decline.
