The Cows usually feed their pups for around 4 weeks and toward the end of the 4 week nursing time, they breed with the Bulls. Soon after breeding, the Cows depart back to the Pacific Ocean and begin feeding again.


The Pups remain on the beach and they become “Weaners,” since they no longer are being fed milk by the mothers, and thus are weaned. After about 8-10 weeks of teaching themselves how to swim, they eventually leave into the Pacific Ocean and begin foraging for food.


Here is a photograph of Cow nursing her Pup.
