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.











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.
