Missing Sea Lions & El Nino

An article in The Seattle Times recently mentioned that several hundred sea lions have disappeared from San Francisco Bay. Where did they go? Apparently, they headed north to the Sea Lion Caves (where else?) in Oregon. One thought is that because of warmer waters off the California coast (one of the El Nino characteristics) that one of the sea lions' favorites foods - anchovies - has migrated north. So the sea lions are just following their stomachs! In addition, the number of sea lions at Heceta Head in Oregon has doubled to 5,000. Wonder if Washington will also see an influx.
