Parakeet hybrids

G.A. Smith (1975)

Article Type: Letter

Some observations on the development of feeding in captive kea (Nestor notabilis)

Notornis, 22 (2), 131-134

H.P. Zeigler (1975)

Article Type: Paper

The feeding behaviour of three young captive kea was studied over a period of eight weeks following their emergence from the nest. The gradual development of independent feeding over this period reflects continuing changes in the relation of the parent and young with each other and with available food objects. The development of species-typical feeding behaviour involving beak-foot co-ordination was not complete by the 19th post hatching week and appears to require a prolonged period of experience with food objects.

Kermadec Islands Expedition reports: the wedge-tailed shearwater (Puffinus pacificus pacificus) in the northern Kermadecs

Notornis, 22 (1), 1-9

D.E. Crockett (1975)

Article Type: Paper

From November 1966 to January 1967 I spent eight consecutive weeks on North Meyer Island in the Kermadec group as a member of the Ornithological Society of N.Z. expedition. Breeding habits of wedge-tailed shearwaters were studied through courtship, egg-laying and early incubation. A flood disrupted incubation and destroyed a part of the study area. Nest-associated fauna and ectoparasites were collected.

Counting birds in New Zealand forests

Notornis, 22 (2), 101-109

D.G. Dawson; P.C. Bull (1975)

Article Type: Paper

Five-minute counts of birds at stations 200 m apart were easier to make and no less accurate as an index of numbers than were counts made while walking slowly through the same forest. The precision and errors of the technique are discussed.
