The southern third (1300 ha) of the Waipapa Ecological Area, Pureora Forest Park, was surveyed for North Island kokako (Callaeas cinerea wilsoni) during the summer of 1990/91. Thirty four territories were located (0.03 territories ha-1). At least 17 of these territories contained a pair, four (23%) of which fledged a total of seven juveniles. A conservative estimate of density was 0.04 kokako ha-1 over the whole study area. These results suggest that there has been a large (up to 60%) decline in kokako density in the Waipapa Ecological Area since the previous survey in 1980-81.
