The status of birds at the Bounty Islands

Notornis, 29 (4), 311-336

Robertson, C.J.R., van Tets, G.F. (1982)

Article Type: Paper

Members of the first party to camp on the Bounty Islands in 170 years report on the ecology, behaviour and history of the penguin, mollymawk, cape petrel, prion, shag and tern that breed there and on the giant petrel, skua, gull and starling that stray there.

The relationships of the New Zealand wrens (Acanthisittidae) as indicated by DNA-DNA hybridization

Notornis, 29 (2), 113-130

Sibley, C.G., Williams, G.R., Ahlquist, J.E. (1982)

Article Type: Paper

The relationships of the New Zealand Wrens have been debated for a century but up to 1981 it has not been clear to which suborder of the Passeriformes they should be assigned. Comparisons between the single-copy DNA sequences of Acanthisitta chloris and those of other passerine birds indicate that the Acanthisittidae are members of the suboscine suborder Oligomyodi, and that they are sufficiently distant from other suboscine passerines to warrant separation as an Infraorder, Acanthisittides.

Sexing black-backed gulls from external measurements

Notornis, 29 (1), 37-40

Nugent, G. (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.
