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 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.

The breeding cycle begins in late September, when the mature males come ashore after their winter at sea to occupy their nesting sites, and ends in early April, when the breeders return to sea following their annual moult. This cycle of nesting and moult is outlined and the main patterns in a complex sign-language of display and posturing are described.

This paper lists the waders recorded in Fiji, summarises information on them collected by the writer during nearly three years residence in Fiji, 1969 to 1971, and compares wader counts made at Parengarenga Harbour, New Zealand, and at Rewa sandbank, Fiji, in January–February, 1971.
