Hybridization of eastern and crimson rosellas in Otago

Notornis, 17 (2), 126-129

J. Hamel (1970)

Article Type: Paper

An examination of the literature and evidence collected from local aviculturalists indicates that the reported wild interbreeding of the Australian eastern and crimson rosellas in Otago is not proven. Even if established this particular instance of hybridization is unlikely to be of taxonomic significance.

Courtship and copulatory behaviour of the New Zealand grey duck

Notornis, 16 (1), 23-32

M. Williams (1969)

Article Type: Paper

The displays and copulatory behaviour of the New Zealand grey duck are briefly described. Courtship is “social,” males gathering together in the presence of one or more females to perform the various sexual displays. Some displays (e.g., ritualized Preens) occur more frequently outside the social courtship groups, between members of a newly-established pair. Qualitative identity exists between displays shared by the grey duck and the mallard.








Mortality and survival of birds during an unseasonable snow-storm in South Canterbury, November 1967

Notornis, 16 (3), 172-179

P.C. Bull; D.G. Dawson (1969)

Article Type: Paper

A severe and unseasonable snow-storm In South Canterbury in November 1967 killed many skylarks, yellowhammers, magpies, thrushes and blackbirds. A total of 810 dead birds, nearly all introduced passerines, were picked up in homestead gardens and around farm buildings during a three-day visit to the area two weeks after the storm began; no dead birds were found in native forest. Several runholders reported severe mortality to wild ducklings and goslings, though adult ducks and geese survived well. Most passerines resumed breeding soon after the snow melted, but yellowhammers and fantails remained extremely rare.
