Abstract
One male and one female Japanese Cormorants, Phalacrocorax filamentosus, breeding at Teuri Island, Hokkaido, foraged within 5km of the island and in the strait between the island and mainland (17-27km from the island). The foraging range of Japanese Cormorants appeared to be limited to the neritic water between 10 and 60m sea depth, where the seabed sediment was mainly rock and sand. Both birds showed high foraging site fidelity, with the male foraging to the south-east and the female to the north-east of the island. The male sometimes foraged in shallow water (<40m), possibly feeding on demersal fish. In deep water (>40m), the male may have fed on epipelagic schooling fish. In contrast, the female did not reach the sea-bottom in deep or shallow waters, and it may have fed on epipelagic schooling fish.
