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.

Song thrushes feeding on mud snails

Notornis, 18 (3), 211-214

P.A. Nye (1971)

Article Type: Paper

Song thrushes Turdus philomelos were found feeding on mud snails at Papanui Inlet, Otago Peninsula. Thrushes break open mud snails with the same technique that they use for garden snails but their hammering must be more persistent because of the thicker shell. The distribution of this habit is discussed and further records requested.

Article Type: Paper

Harrier pellet castings and prey remains were collected over an 18 month period from a regularly used preening site adjacent to a nest. Other prey remains were gathered from that nest and two others. It was concluded that a large part of the food eaten consisted of carrion.
