Cape Fur Seal Arctocephalus pusillus predation on Cape Cormorants Phalacrocorax capensis and other birds at Dyer Island, South Africa



Cape Fur Seal Arctocephalus pusillus predation on Cape Cormorants Phalacrocorax capensis and other birds at Dyer Island, South Africa



Marine Ornithology 25(1-2): 9-12



Between summer of 1994 and winter of 1996, a period covering two breeding seasons, at least 2461 newly fledged Cape Cormorants Phalacrocorax capensis were taken as prey by Cape Fur Seals Arctocephalus pusillus at Dyer Island, Western Cape, South Africa. The estimated minimum level of predation for the first of these seasons is 7.3% of the available cohort. This is the first report of substantial predation on cormorants, and records predatory behaviour patterns also reported in other otariid seal species. Prey-handling techniques are described.
