The effects of logging on winter bird populations near Karamea

Notornis, 30 (3), 187-197

D. Onley (1983)

Article Type: Paper

Winter 5-minute bird counts in unlogged and logged native forest near Karamea showed substantial declines in native forest species after logging and a varied response from introduced species.

The affinities of the New Zealand passerine genus Turnagra

Notornis, 30 (4), 319-336

S.L. Olson; K.C. Parkes; M.H. Clench; S.R. Borecky (1983)

Article Type: Paper

The external structure, pterylosis, myology, and osteology of Turnagra show that this genus belongs in the bird-of-paradise/ bowerbird assemblage and is not closely related to the Pachycephalinae. Turnagra appears to be the most primitive member of this assemblage, sharing similarities both with the paradisaeid subfamily Cnemophilinae and with the Ptilonorhynchidae.

A banding study of North Island brown kiwis in an exotic forest

Notornis, 30 (2), 109-124

R. Colbourne; R. Kleinpaste (1983)

Article Type: Paper

Territory, distribution and dispersal of the North Island brown kiwi (Apteryx australis mantelli) were studied at Waitangi State Forest, Northland, from February 1981 to July 1982. In all, 84 kiwis were banded and individually coded and 220 resightings were recorded. Weights and bill measurements are given, together with some growth rate data. Territories of 23 birds are shown and these approximate 5 ha per adult pair, but territory size may decrease with greater abundance of food and with immigration from logged areas. Kiwis frequent many burrows within fixed territories, and males defend these territories from other pairs, primarily by calling. Juveniles under 1 year old are accepted in these ranges, whereas larger juveniles and some females do not have regular haunts. Kiwis try to retain their territories in the face of logging and other forest management practices and this behaviour demonstrates the importance of site attachment. Swamp margins and swamp arms are important to kiwis as a temporary refuge after clearfelling and as feeding areas during dry periods of the year. Despite the forestry practices the Waitangi kiwi population is thought to be viable.

The spotless crake (Porzana tabuensis) on Aorangi, Poor Knights Island

Notornis, 29 (1), 9-21

D.J. Onley (1982)

Article Type: Paper

Fewer than 50 adult spotless crakes (Porzana tabuensis) plus 24 chicks and four juveniles were found on Aorangi in February and March 1980. They were confined to the valley and preferred a low mixed forest which is being replaced by a less favoured habitat. Habitat preference is discussed and related to changes in numbers in the past. Clutch size is lower than on the mainland and chick production probably lower. The breeding cycle is long. Some observations on the adult-chick relationship are presented.
