Kokako ( Callaeas cinerea ) in the Hunua Range, Auckland, 1992-1994 | Notornis and Birds New Zealand

[摘要] Five surveys for the North Island Kokako were carried out in the Hunua Range, Auckland between October 1992 and March 1994. Twenty six-28 Kokako were recorded, including 3 possibly 4 pairs. Results suggest that there has been a decline in Kokako numbers since the previous survey in 1986-1988. All Kokako were recorded in tawa-podocarp forest. The birds ranged in altitude between 320m and 640m. Birds were distributed in the following catchments: Mangatangi (13 birds), Mangatawhiri (12 birds), Orere (2 birds), Tapapakanga (1 bird). Nearly all records (65%) were of birds heard rather than seen. Two pairs were seen.
