Elephant Seals on the Pocket Beaches

Females Resting Onshore               Males Challenging in a Bay 
At this time of year, when both the females and males of all ages excluding the adult males come ashore to experience their catastrophic molt, they often choose separate pocket beaches. Maybe they do so because the females don't want to be mounted all the time by young males....and maybe because the males are more intent on asserting their strength, both mental and physical, over each other.

Although both sexes tend to sleep quite a bit, therein ends the likeness. The once-again pregnant females crowd onto the small beaches and spend much of their time squabbling about one thing or another as they wait not so patiently for the time when they'll leave the central California shores to feed themselves and their growing fetus. How they decide when to leave again is not known. Maybe their hunger pangs get too strong, or maybe they somehow know that their favorite meals are out and about. One thing that is obvious, is that the females seem to prefer spending their time ashore, often on beds of cooling kelp rather than in the chilly Pacific Ocean.

The males, on the other hand, tend to occupy their coastal-time by constantly challenging other males. These challenges take place both in the shallows as well as on land. From the day they're born, male elephant seals almost constantly challenge one another...presumably for supremacy.

These groups will soon be on their way in search of food, and won't return to these shores until early fall. The next group to come ashore starting in late June will be the adult males.

BIG Adult Male Elephant Seals Starting to Show Up

l

Taking a well-deserved nap


As the Fall Haul-Out heads to its close for this year, a smattering of the large adult male elephants seals can already be seen sleeping and snoring on several of the beaches along the central California coast.

So far, the bloody and sometimes protracted fights for territory have not yet begun. This may in part be due to the fact that these huge males are quite exhausted from their almost continual search for food while at sea and need to sleep so they can recoup their massive strength. Another contributory fact might be that there are so few adult males here this early that territory is not yet an issue.

Quite a few pregnant females can also be observed resting on the beaches along with the remaining sparring sub-adult males as well as more than a few left-over weaners and two- and three-year-old youngsters.

The fur of these youngsters, which has changed to a beautiful golden or pale tan color, will be shed during next year's molting season.

Most of the elephant seals look well-fed this year, and their fur lacks the blemishes of last year. Also, the amount of cookie-cutter shark bites seems less than in time gone by.

As the days in December roll by, more and more adult males will be coming ashore and the showdowns for territory will take place more and more frequently until the pregnant females arrive and start to give birth, with the first births coming maybe as early as the middle of December.

Time for the Yearlings


With only a couple of large male elephant seals still on the beach, the emphasis now is on this year's weaners and two- and three-year olds as they hustle ashore to begin their Fall Haul-Out rituals.

Like the older elephant seals, they joust, albeit with less ferocity, disturb each other for a variety of reasons, sleep, and swim in the shallows.

When the older elephant seals come shore, they usually spend quite a bit of time in deep sleep. The younger ones, however, seem to be more filled with vim and vigor !

Weaner Time


This time of year is all about weaners ( AKA weaned elephant seal pups )on the beaches of the central coast of California.

With almost all of the females departed out to sea to forage and regain the pounds lost during their birthing and mating time ashore, the weaners are now having to learn how to take care of themselves.

The weaners are not completely without adult supervision though as some watchful and protective adult males remain on the beaches until the weaners get more proficient at swimming and start beach hopping.

Newly weaned weaners, like the older elephant seals, spend a lot of time sleeping while on shore as they're conserving energy and subsisting on their blubber.

As the weaners grow restless however, they spend less and less time sleeping and more time moving around the beaches and bluffs and communicating with each other. Also, as time passes, they start honing their life-essential swimming and foraging skills.

If weaners are to survive and grow to adulthood, it's imperative that they quickly learn how to find food and protect themselves both on land and at sea.
