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.

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.

Seabirds found dead in New Zealand in 1980

Notornis, 29 (1), 41-47

C.R. Veitch (1982)

Article Type: Paper

During 1980, 2,736 km of coast were patrolled by 146 members of the Ornithological Society of New Zealand and their friends. 4,351 dead seabirds were found. There were no major wrecks. During one patrol sooty shearwater (Puffinus griseus) were found at a rate of 68.5 per kilometre. Unusual finds were: eastern little tern (Sterna albifrons), grey ternlet (Procelsterna cerulea), brown booby (Sula leucogaster) and yellow-nosed mollymawk (Diomedea chlororhynchos) which is also a new record for the Beach Patrol Scheme.
