Horuhoru revisited – longevity of the Australian gannet

Notornis, 18 (4), 310-365

P. Stein (1971)

Article Type: Paper

On 31 December 1970 an adult gannet was trapped on Horuhoru close to where it had been banded on 20 February 1954. It had been hatched on 19 December 1953, and was therefore slightly over 17 years and one week old. Here we describe the work undertaken in banding chicks on the islands in the Hauraki Gulf, to find where they go while developing from juvenile to adult plumage, and when and where they return to breed.

The identity of New Zealand’s Canada geese

Notornis, 18 (4), 253-261

M.J. Imber (1971)

Article Type: Paper

Canada geese Branta canadensis became established in New Zealand following the introduction of 50 from central or eastern U.S.A. in 1905. In 1920 ten more were brought from western Canada. Examination of plumage, weights and measurements of the present population shows that it belongs predominantly to the giant race B. c. maxima Delacour. There is a possibility that B. c. canadensis interbred to a limited extent with it. Behaviourally and ecologically maxima appears very well suited to the South Island habitats in which it multiplied quickly.
