Feeding ecology and body size dependence on diet of the sooty shearwater, Puffinus Griseus, in the North Pacific
The diet of the Sooty Shearwater (Puffinus gnseus) was examined by using a total of 1139 stomachs of the bird sampled during April-October, 1982, 1985-1989. Of all stomachs, 586 were empty. Predominant prey species was the Japanese sardine (Sardmops melanostictd), the wet weight percentage of which...
