Birds observed during landings on four islets of the
Western Chain, Snares Islands, in February 1984 are discussed.
A census of Salvin’s Mollymawk revealed 586 chicks on two of
the islets and one stack, and so the population is not likely to
exceed 650 pairs. The numbers of the eight other bird species
known to breed on the Western Chain were estimated, and their
distribution is described. Measurements of 20 chicks of Snares
Crested Penguin indicate that the breeding cycle on the Western
Chain is about six weeks later than on Main Island.
Buller’s Mollymawk, Mottled Petrel, Sooty Shearwater,
Scuthern Skua and Red-billed Gull are new breeding records for
the Western Chain, and eight other species observed had not
been reported previously.
