Pīpīwharauroa (Shining Cuckoo)
The shining cuckoo (shining bronze-cuckoo in Australia) is a summer migrant to New Zealand. It is common throughout New Zealand but it is small and cryptically-coloured and so is more often heard than seen. It has a distinctive whistling call. Two intriguing aspects of its life history are its brood-parasitic habits and the long annual trans-oceanic migration. The New Zealand subspecies breeds only in New Zealand (including Chatham Islands) but other subspecies breed in southern Australia, Vanuatu, New Caledonia and on Rennell and Bellona Islands (Solomon Islands).
Shining cuckoos are heard, and often seen, on Tiritiri Matangi every year, though it is not clear whether they breed on the Island or simply pass through. Breeding is possible, as there are resident grey warblers, though these are not as common on the Island as many other birds.
