Comments: Opportunistic feeder. Feeds on squid, octopus, and a various fishes, including herring, anchovy, whiting, mackerel, sardines, hake, rock-fish, etc. Males do not feed during breeding season. Lactating females at San Miguel Island forage with 100 km of rookery, in highly productive upwelling areas; most feeding dives are relatively shallow (26-74 m) (Reeves et al. 1992).
