Seabirds seen in the northern Tasman Sea in winter

Abstract

Summary The distribution of birds in the northern Tasman Sea was observed during August and September 1967 from r.v. Argo. Subantarctic species (Diomedea exulans, D. melanophris and Daption capensis) ranged further north in the western than in the eastern Tasman Sea, probably because western waters have a higher phosphate content and hence contain more food. New northernmost sightings were recorded for Pachyptila sp., Pterodroma macroptera, Pelecanoides sp. and Procellaria cinereus.
