Foraging and social behaviour of the White-faced Heron at Pauatahanui Inlet

Notornis, 31 (4), 285-299

P.J. Moore (1984)

Article Type: Paper

During a study from January to June 1982, White-faced Herons (Ardea novaehollandiae) visited the mudflats of Pauatahanui Inlet in greatest numbers in summer and declined after April as they dispersed to farmland. When foraging, they were essentially searchers, usually wading and walking, but occasionally standing and waiting for prey. They also used more active feeding methods, disturbing prey by foot-stirring, wing-flicking, and false striking with the bill, and pursuing prey by running, wing-flapping and hopping. How they captured and handled prey depended on the prey species. White-faced Herons maintained variable individual distances using several agonistic displays, including forward and upright displays, chases, fights, and associated calls.

A bird in the hand: Andreas Reischek and the Stitchbird

Notornis, 31 (4), 300-311

G.R. Angehr (1984)

Article Type: Paper

Early accounts of Little Barrier Island by Andreas Reischek emphasise that the Stitchbird (Notiomystis cincta) was very rare there in the 1880s. Re-examination of the original accounts, in conjunction with dated specimens, suggests that the Stitchbird was in fact very rare in 1880 and 1882 but increased markedly in 1883 and 1885. The rarity of the species on Little Barrier in 1880 and 1882 coincided with its extinction on the mainland and may have been due to introduced disease. However, several fluctuations in population size have taken place since. At least 78 and up to 130 of the 181 extant 19th-century specimens were taken by Reischek.

The North Island Kokako (Callaeas cinerea wilsoni) in the western King Country and Taranaki

Notornis, 31 (2), 131-144

O'Donnell, C.F.J. (1984)

Article Type: Paper

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.

Buller’s mollymawks breeding at the Three Kings Islands

Notornis, 31 (3), 203-207

A.E. Wright (1984)

Article Type: Paper

A small breeding colony of Northern Buller’s Mollymawks (Diomedea bulleri platei Reichenow, 1898) is recorded from the Three Kings Islands off northern New Zealand. The subspecies was previously known to breed only at the Chatham Islands, which lie 10 degrees of latitude south of the Three Kings.
