Cape fur seals (Arctocephalus pusillus pusillus) prey on Cape gannets (Morus capensis), Cape cormorants (Phalacrocorax capensis), bank cormorants (P. neglectus), crowned cormorants (P. coronatus) and African penguins (Spheniscus demersus) at Ichaboe Island (26°17'22"S, 14°56'36"E), Namibia. Between September 1991 and May 2000, 2774 predatory events were recorded; these involved 932 gannets, 1217 cormorants and 544 penguins. One-third of predation events noted were on seasonally abundant fledgling gannets and cormorants. Four individual seals specializing in seabird predation did not conform to this pattern of predation, differing in bird species targeted. Seabird predation may be learnt from other seals, or forms an extension of play behaviour predominantly in subadult males. Seabird predation does not seem to be a common, stereotyped behaviour in seals; rather, individuals develop their own preferences and techniques. Key words: Cape fur seals, seabirds, predation, Ichaboe Island.
