Geographical variation in the Buff-banded rail (Gallirallus philippensis) in the south-west Pacific (known as the banded rail in New Zealand) is reassessed in the light of the origin of island stocks and nomadism. Nomadism appears to have diluted divergent evolution on small islands and (sub) continental mainlands throughout the region, and from it lines of colonisation from mainland sources have been adduced. There appear to be no justifiable subspecies on mainland Australia, and others on islands in the Bismarck Sea are open to question; one new subspecies, G, p. tounelieri, is described from cays in the Coral Sea.

The food of honeyeaters (Stitchbird, Bellbird and Tui) was studied on Little Barrier Island in April by collecting droppings and pollen from mist-netted birds. All three species were taking nectar from puriri and climbing rata. Stitchbirds were the most frugivorous and Bellbirds the most insectivorous of the three species.
Authenticated records of chewing (feather) lice, largely from unpublished observations, are listed from birds in the New Zealand zoogeographic subregion, including the Ross Dependency in Antarctica. From a total of 388 host taxa (including 38 introductions), lice are reported from 250 hosts (including 27 introductions). These records comprise 267 lice species and subspecies; a further 138 records are listed at generic level only,
but all these do not necessarily represent separate species. Although some bird groups have been collected from frequently, there are many gaps in our knowledge, even for these hosts. With some orders (e.g. Passeriformes) and families of birds, little or no attention has been paid to their ectoparasites. An appeal is made for assistance in building up collections.
