Mainly Weaners


As March draws to a close, the pups which were born this birthing season have since been renamed weaners. ( I don't know who came up with this 'ingenious' terminology at some point in time.) The pups are weaned abruptly from their moms after feeding almost non-stop for about 4 weeks and gaining anywhere from a couple of hundred pounds to even as much as 7 times their original birth weight in this relatively short nursing period. The moms are hungry and eager to get back out to sea to replenish their lost body weight, which means that the newly weaned pups AKA weaners are pretty much left to fend for themselves. However, a few young adult males can still be seen hanging around the beaches maybe to protect these youngsters from immediate harm. After all, coyotes do sometimes traverse the beaches in search of food !


The weaners will remain on the beaches for about another month or so living off the fat-rich milk they ingested from their moms. During this time, they'll practice the art of swimming and diving in protected tide-pools or creeks to build up their muscle strength. Also, the black/brown pup fur will finish shedding and reveal the sleek new silver-gray fur associated with weaners.


Weaners are very chummy and like to talk and physically interact with one another. The males are already starting their practice fights and setting up supremacy ladders. The females are quieter...they don't practice fight like the males. Instead, they do a lot of stretching, fending off male weaners, and sleeping. Weaners do need to sleep a lot in order to preserve their body fat for as long as possible. Sometimes, you can even see weaners testing out the edibility of dry kelp, sticks or other objects lying on the beaches.

Eventually, the weaners will decide it's time to start seriously looking for food and start beach-hopping in search of nourishment. During this time, they'll also hone their life-necessary fishing skills. Most weaners will head northward following the trails of the adult elephant seals. Then they'll return again to the vicinity of their birthing beach in the late summer/early fall in a period called the Fall Haul-Out when they'll rest, practice fight, and generally socialize for about a month.

Keys to Successful Elephant Seal Mating



Despite their fierce reputation, elephant seal males are, for the most part, quite peaceable except for when it comes to territorial rights and mating.

Click here for recent photos of the current residents at Elephant Seal Land.

Male elephant seal dominance fighting is part of their disposition, and, for the most part, these battles are fought without rancor.

Prior to this birthing/mating season, I've hardly ever seen a truly angry male elephant seal. This year, however, tolerance and patience seem to have been somewhat short on a few occasions.

Also, since the mating season is in full swing, I thought it a good idea to try to describe with words, photos, and videos what actually leads up to a successful union.

Click here for photos of mating.

Alpha Male or Beachmaster is the term given to the dominant male that 'owns' a certain segment of the beach with all its resident females, pups and weaners. This time of year is an extremely busy one for these large males as they make valiant attempts to mate with ALL of the females of their so-called harem. In between convincing their females to mate, these huge males can be seen galloping madly across the beach staunchly defending 'theirs' from any and all would-be intruding lovers.

Below are some tongue-in-cheek tips that might be handed down from father to son throughout the realms of Elephant Seals.

Advice for a Would-Be Lover

1. Sneak ashore. Hide amongst the females and pups. Don’t draw attention to yourself.

2. You may have to go ashore behind the back of the alpha. Use waves, rocks and other seals as cover.

3. Try to find a quiet female. ( Almost impossible )

4. Quickly try to mount when opportunity arises….but keep and eye and ear open for an irate advancing alpha. Always be prepared to flee. Know where your quickest path back out to sea lies.

5. Wait for alpha to get tired from exertion, then make your move.

Advice for the Alpha Male

1. Keep other males away by patrolling waters and chasing amorous intruders off beach.

2. Allow some large males on peripheries to chase off other would-be lovers. ( Saves your time and energy. )

3. Choose a compliant female. Stay away from feisty females who bite and struggle fiercely to escape. Also watch out for females that gang up on you.

4. Don’t get interrupted by other advancing males.

5. Herd escaping females back to shore.

Butterball Weaners



Despite the extraordinarily aggressive behavior of many of the moms this birthing season, most of the pups have flourished and many are now entering the stage of weanerdom. ( The pups are renamed weaners when the mom turns off the milk spigot after about 4 weeks of nursing and heads out to sea to feed and replenish her lost weight, leaving her offspring on shore to fend for itself. )

The biggest danger to the pups this birthing season has not been severe storms or amorous males looking to mate but the unusally pugnacious actions of many of the moms. These females have been quick to dash across several yards of beach to bite or even pick up and toss pups through the air with extreme regularity as can be evidenced by the large number of cuts and bite marks on nearly all the pups/weaners.



Maybe because the alpha males have successfully kept at bay what few love-struck males have tried to gallop across the beaches to mate with unwilling females, the nursing pups and their moms have largely remained uninterrupted over the bulk of the birthing season.

( It's not that the males intend harm to the pups, but their intrusions create unrest and force the moms and pups to keep moving around, cutting into nursing times and causing them to use up precious calories.)

Click here to see video of pups/weaners trying to wiggle their way out from under a huge bull.

In the photos, you can see how truly huge some of these weaners have become. Some of them have even almost attained the length of their moms in just a few short weeks of gorging themselves !
( Since so many of the weaners are big, round and comical this year, I feel tempted to nickname them butterballs.)

Click here for weaner and pup photos.

Nevertheless, in the last few days, more males have been starting to show up, and now the previously half-hearted mating attempts are getting more serious. At least these males are starting to achieve their goals with the now more complacent younger adult females before gettting run off the beaches by this year's more-than-usual protective alpha males or other large males intent on getting their share of the mating. ( Scientists claim that the females enter into estrus about 3 weeks after giving birth. )

The Start of the Fall Haul-Out


As almost all the big adult male elephant seals have left to fortify their strength and body weight in preparation for the up-coming December territorial fights, the beaches along the central coast of California are currently occupied by only a few dozen mainly tan-furred youngsters doing their thing.

As September heads towards October in this Fall Haul-Out season, however, more and more elephant seals in the younger age brackets will be looking to enjoy spending some quality shore-time on these usually noisy and busy beaches.

Adding to the mix of weaners and yearlings as we go through October, energy-filled ‘teenage’ males will be charging ashore delighting onlookers with their rock-’n’-roll style fights. In addition, alongside these combative youngsters, a few pregnant young females will also be trying to get some shore-rest on the ‘quiet side of town’ away from the boisterous young males.

...And the Males Are Still Here


We're half-way through August, and there are still quite a number of large adult males hanging around the beaches at Elephant Seal Land. Though not as feisty as a few weeks ago, you can still see sporadic short encounters, but it looks as though they're mainly resting up before taking off on yet another foraging trip.

Click here to see some action close-ups.

Into the mix of the remaining giants, a handful of small weaners can already be seen resting or mildly sparring like young puppies.

Click here to see a cute video of a couple of weaners playing like puppies.
( The remarkable thing is that one's a female and the other's a male. Usually you only see young male weaners interacting in this way.)

Molting Time for Females and Juveniles


The first group of elephant seals to return to the beaches on the central coast of California to start their molt are the adult females. Pregnant once more, and having regained their lost weight during the recent birthing/mating season, they have once again taken over their favorite beaches in order to rest and shed their old fur, which has become tan-colored over time. Some of these adult females are really huge...close to 10 feet in length and looking rotundly healthy after only having been absent for a month. It's hard to believe that they left about a month ago looking thin and worn out.

The catastrophic molt, as it's called, takes close to one month to complete. During this time the 'old' fur and attached skin comes off in large pieces so that the new sleek gray fur can be exposed and readied for 'duty'. During this changeover, the elephant seals seem more sensitive to heat than otherwise and can be seen lying either at the water's edge or swimming in the cool Pacific waters if the mercury starts to rise.

At this time, since there are no large males around, the adult females are the dominant ones on the beaches. Amongst these constantly bickering females, one can also see molting juveniles of both sexes and quite a few newly-arrived weaners that are beach-hopping their way to the hunting grounds.

One- and two-year-old elephant seals sometimes suffer from scabby molt, believed to be a skin disease rather than a true molt. ( Click here to read more. )

As April proceeds, sub-adult males will start to come ashore to start the molting period.

Weaners Galore


Since the threat of a far-reaching tsunami caused by the devastating 9.0 earthquake in Japan has finally dissipated, one would think that the elephant seals camped out on the shores of the central coast would continue their regular business.

Most of the current elephant seal population is composed of this year's pups, who recently matured into weaners. The majority of these have gathered together in oversized weaner pods on just a couple of the local beaches in the Piedras Blancas area instead of being dottted along the coast as in previous years.

An observer might be amazed as the members of the weaner pod at the north end of the Piedras Blancas viewing center seem to be unusually active, feisty and agitated - biting and snapping at anything and everything that's in their vicinity rather than mainly sleeping away their days, conserving energy. Extreme backbends also seem to be the order of the day as many of these maybe not-so-small twirling dervishes are making the most of a pool formed through a combination of high tides and water deposited from a large agricultural drainage pipe.

Click here to see video of weaners in pool.

Another interesting point is the amount of large adult male elephant seals that are still present. One could say that they're there to protect the weaners. But are they ? Scientists believe that the adult males are only interested in mature females. However, my observations of the adult males would seem to point to their protective nature not only towards females but also towards the pups and/or the weaners.

So far, only a handful of the females have returned to the beaches to rest and start their catastrophic molt. Additionally, on some of the small pocket beaches, a few well-fed young males have already hauled out to begin their molting period.

Pups Becoming Weaners



All but the last few exhausted mommy elephant seals have left to replenish their rapid weight loss which took place during their month-long shore sojurn. Giving birth and suckling their pups without possibility of leaving land for about 28 days to get some sustenance caused them to lose about 1/3 of the body weight they had when they first came ashore this winter.

The pups, most of whom are more than chubby this year, have been renamed weaners, weaned from suckling, and their only adult protection now is from some of the remaining large males.

Many of these weaners hang out in varying-sized groups known as weaner-pods. Whether they do so for safety in numbers, for comfort from physical closeness to others, for warmth, for the social aspect or what, the scientists are not sure. One thing is sure, though, their interactions with one another are often hilarious to watch.

Over the next month or so, the black/brown pup fur will be exchanged for the eye-catching silver gray fur that's specific for the weaners during their first year. Like all sea-going creatures, their new backside fur is darker than their belly fur, making them less visible to their predators in the ocean.

During their first month as weaners, they will start exploring the shallow tide-pools and/or creeks honing their vital foraging, swimming and diving skills. In so doing, they often get caught up in the ocean currents and land up, intentionally or otherwise, at a different beach, which I call this beach-hopping.

My next posting will deal with the adventures of maturing weaner.

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.

Fall Haul-Out Continues


As the Fall Haul-Out for 2010 continues, different elephant seals keep coming ashore for some R&R while those that have already spent close to a month on land leave in search of food.

After the young male elephant seals have recovered from their trip to the central coast beaches of California, they start their fights for dominance.

However, the female elephant seals of all ages that come ashore at this time of year do so to get some rest trying to keep their distance from the young and actively aggressive young males.

Expectant onlookers can almost always be assured of being witness to the varying shows of aggression provided by the young male elephant seals in their almost continual fights for dominance both on land and in the water.

All too soon, however, these younger elephant seals will be off to sea again looking for more food. Then, in about six weeks, the big male elephant seals will start to come ashore and the battles for temporary territory will begin.

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 !

August at the Piedras Blancas Elephant Seal Colony


Most of the adult male elephant seals have completed their catastrophic molt, and many have already 'set sail' for their feeding grounds in order to gain the necessary bulk for their winter stay of about 3 months starting in December.

Early though it is, a few weaners and yearlings have already come ashore for their fall haulout, joining the remaining adult males.

As we progress toward September, more and more youngsters as well as adult females and young males will come ashore to rest for about a month before setting off to feed again.

Catastrophic Molt


Prime beach space is beginning to be hard to find as more and more large elephant seals work their way up onto the beaches to join the already present weaners. These weaners, who are further honing their swimming, diving, and foraging skills now have to try to stay out of the way of the older elephant seals as hierarchy rules.

Over the last couple of weeks both adult female elephant seals as well as juvenile males ( juvenile male = 1-4 years old ) and juvenile females ( juvenile female = 1-2 years old ) have been crowding onto the beaches of central California to begin their annual catastrophic molt. ( The sub-adult males and adult males will come a little later on for their turn.)

What is a catastrophic molt ? Over a period of many months, elephant seal fur changes color from a gray to dark brown to a lighter brownish hue or even a pale tan.

Maybe this change in fur pigment indicates that the fur becomes less oily over time causing the elephant seal to shed its fur and attached skin about once a year. Also, maybe because the elephant seal spends so much of its life in the salty ocean water, its fur simply has to be replenished as the salts dry it out. Another factor might be that as the elephant seal expands both in length and in girth, it needs to shed its outer layer much like a snake does.

The fur and skin peel off in both larger and smaller pieces revealing the fresh new layer of gray fur below. ( See extra photos.)

During the month this molt takes to complete, scientists believe the molting elephant seals eat nothing even though they often enter the ocean during this period.

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.

Over-Sized Elephant Seal Weaners


Despite quite a few pups starving to death ( see blog post 2-6-10 ), there also seems to be an inordinate amount of extra large weaners occupying a certain beach on the central coast of California.

The average weaned pup AKA weaner is between 4 and 5 feet long and weighs anywhere from 150lbs to just over 300lbs. ( Bear in mind that when one of these weaners was born a little over a month ago it was 3-4 feet long and weighed 60-80lbs.)

At this one beach, I have been astonished to observe that about 50% of the weaners are extremely huge. Their lengths are 5-6 feet, and they must weigh in at around 500+ lbs.

( Remember, a full-grown adult female is on average 8-9 feet long and weighs anywhere from 800lbs to 1,500lbs....and this is after several years. )

Why have so many weaners grown to this gargantuan size ?

Maybe this phenomenon came about because the moms and their pups became isolated up in the dunes and had plenty of undisturbed nursing time !? Due to the constant high waves and high tides during the merciless winter storms, sheer sand bluff walls were formed keeping the large male elephant seals at bay for several weeks down on the flats of the beach until they were able to wear down the sand walls and climb up into the lofty nursery.

Male Elephant Seals Getting Antsy


As the birthing season continues, and more and more suckling pups can be found on the diminished beaches despite the harsh winter storms and devastating high tides, the males are getting more and more eager to mate.

Apart from periodically viciously chasing unwanted male challengers off the portion of the beach they call theirs, the male elephant seals can usually be seen lying on the beaches preserving their strength in preparation for the task of mating with as many females as possible.

In the meantime, the young pups are suckling hard and often, growing fat in the process on their way to becoming weaned pups AKA weaners. ( So far, there are only a handful of weaned pups, born early on in the birthing season in December.)

To add to the mix, the females continue their bickering over space and pups and try to keep ardent males at bay till they come into heat starting a few days before the end of their nursing period of about 28 days.
