Sexing black-backed gulls from external measurements

Notornis, 29 (1), 37-40

G. Nugent (1982)

Article Type: Paper

Six body measurements were taken from 283 adult and sub-adult black-backed gulls (Larus dominicanus) in Auckland, New Zealand. Sex was determined in 158 of these by dissection or chromosomal methods. Using measurements from these 158 birds a classification function was derived and used to assign sexes to the remaining 125 gulls. Discriminant analyses were then made on the measurements from all 283 birds to describe the sexual size dimorphism accurately and to derive a simple classification function for the routine sexing of birds in the field.

Patterns of variation and dispersal in the buff-banded rail (Gallirallus philippensis) in the south-west Pacific, with description of a new subspecies

Notornis, 29 (2), 131-141

R. Schodde; R. de Naurois (1982)

Article Type: Paper

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.

A list of the chewing lice (Insecta: Mallophaga) from birds in New Zealand

Notornis, 29 (Supplement), 1-32

R.L.C. Pilgrim; R.L. Palma (1982)

Article Type: Paper

Authenticated records of chewing (feather) lice, largely from unpublished observations, are listed from birds in the New Zealand zoogeographic subregion, including the Ross Dependency in Antarctica.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.

The food of honeyeaters (Meliphagidae) on Little Barrier Island

Notornis, 29 (3), 209-213

P.D. Gaze; B.M. Fitzgerald (1982)

Article Type: Paper

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.
