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.

Territories of South Island fernbirds

Notornis, 30 (3), 199-216

M. Barlow (1983)

Article Type: Paper

South Island fernbirds near Invercargill, Southland, were studied for two years. Adult birds had year-round preference for areas with low dense ground vegetation and emergent shrubs. The preferred habitat occurred in a linear strip along an estuary margin. Territories were contiguous and distributed in linear fashion along the strip. Territory areas varied from 530 m2 approximately to 2870 m2 approximately. Territories were strongly defended during the prebreeding and breeding seasons, and defended to some degree at other times. Juveniles were often found outside the preferred adult habitat. There were indications that total fernbird population needs may include an area adjacent to but exclusive of adult territory areas. Fire had a prolonged adverse effect on breeding habitat.
