'Tis the season!

Newborn pups in the sand

A few fully mature bulls are on the beach, along with a few pregnant females and a few pups already born. The first pup was born December 10. The second was born December 18, with more following. It’s like popping corn: pop, then pop, then pop pop pop pop pop.


Dominance settles conflict

Elephant seal mothers do an excellent job, under the circumstances. The few mothers who begin the season, with plenty of space around them on the beach, are tempting to young, less dominant males. The attraction is overwhelming, even though the mothers will refuse the males until they come into heat, after they have nursed their pups for a month.

The full-grown beachmasters aren’t imposing discipline on those upstarts yet, but watch for signs of dominance. Although the goal of battling is to establish the dominance hierarchy, once the beachmaster prevails, he can reduce conflict. Just seeing him makes less dominant bulls bustle away.

A young bull approached that first mother and pup, nudging and shoving her around. She got separated from her pup, which can be serious if they aren’t reunited. A pup separated from its mother can lose out on that rich milk, and even die.

The beachmaster rumbled up toward that miscreant, who looked over his shoulder and headed in the other direction. Mother found her pup and all three settled down to a long winter’s nap.

Pups are born night and day



You may be lucky enough to be watching when one is born. Watch for females fussing and tossing a lot of sand. They sometimes toss so much, they build a sort of perch for themselves, with deep ditches dug out on both sides.

Birth starts with a gush of amniotic fluid, as the water breaks.



Wildlife viewing requires patience. Pregnant females will continue to arrive on the beach, into February. Check the live webcam for beach conditions, www.elephantseal.org.

Pups are all black, about three feet long and weigh about 70 pounds when they’re born. They soon plump up on their mothers’ nourishing milk. They’ll nurse for a month. In the last few days of nursing, the mothers mate with one or more males. They wean the pups abruptly when they return to the ocean.

Watch seals from a distance

Bulls that lose out find their way to other local beaches, sometimes called bachelor beaches.

Hearst Memorial Beach at San Simeon Cove attracts them. Human beach visitors may be surprised by a seal among the driftwood.

FES will post guides there for the duration, through March, to advise visitors as to seals they may encounter.

The seals are not aggressive toward humans, but the bulls that come to San Simeon may challenge other bulls to fight on the beach. Human visitors stay safe by giving the seals a wide berth. NOAA Marine LifeViewing Guidelines advise no closer than 50 yards, half a football field. Keep the dog leashed so as not to annoy them. Don’t get between two seals, who may decide to charge each other, or a seal and the water, in case he suddenly decides to go back into the waves.

Informed beach visitors can coexist with the seals. The Piedras Blancas rookery is an example of seals and humans sharing the beach. Stay safe and give the seals time to rest.
