Strewn out on the beach, continuously flipping sand over their backs, the elephant seals of the Piedras Blanca are an amazing sight. Now and then two or more rear up challenging each other with mock battle roars It is breeding season in the elephant seal community.

They first appeared on a secluded beach just south of the lighthouse in 1990. It was an extraordinary occurrence that delighted the public travelling Highway One north of San Simeon.

By the end of the 1880’s they were thought to be extinct. Whalers and sealers had hunted them for their blubber. A small colony, between 20 to 100 individuals managed to survive and took up residence on Guadalupe Island, off Baja, California.

All of the elephant seals on the West Coast of the continent are descended from this group.

Some elephant seals are always present at Piedras Blancas, but the most interesting time to visit is during breeding season from November through February. Beaches are jammed with chubby females giving birth, little black pups
suckling, and huge blubbery males doing battle.

Male seals begin to arrive in late November and stake out their positions on the beach. Dominant bulls, the ones that have the best chance to mate with the most females, threaten away lesser males and take up residence waiting for the females to arrive.

One of the most exciting things to witness is a battle between two of these large bulls. When approached by another male, the resident bull will rear up on his hindquarters, throw his head back, and roar out a threat. His large bulbous nose dips down into his gaping mouth. Then each bull rears up and with great force they slam their bodies at each other, slashing away with their large canine teeth. Fights can last a few minutes or go on for hours. Usually the battle ends with one bull being forced into the water or backing away submissively.

Pregnant females arrive on the beaches in December and, after four or five days, give birth to one pup that arrives thin, wrinkled and black. Most pups begin to suckle soon after birth. Elephant seal milk is the richest of all mammals with a high percentage of fat. The pups gain weight quickly on this, doubling and quadrupling their size in less than a month.

 

Nursing lasts for about 28 days. In the last three to five days the females are ready for breeding. Now the alpha bull takes advantage of his position to mate with the most females. Within a month after giving birth, females are impregnated. A little more than a month after arriving at the rookery, the female heads out to sea leaving her now plump, molting pup on shore.
