I heard back about more information on the recently arrived female juvenile elephant seal pup, with green tags E103 and E135. Dr Patrick Robinson, the Director of the Año Nuevo Reserve and Lecturer at University of California Santa Cruz, sent a report of the history of the seal’s sightings and said, “It’s always great to get these updates… we greatly appreciate it!” The seal was born in the 2018 winter season, which makes her just over two years old. She was seen a lot during the winter and spring of 2018 at Año Nuevo Reserve. Researchers took two blubber samples to study bioaccumulation. The seal wasn’t seen again until the fall of 2019, when she spent a month at Race Rocks between September 7 and October 11. Fast forward a few months, the seal came back to Race Rocks two days ago, on March 23. She appears to be in the early stages of her catastrophic moult of her fur and skin, judging by the patches on her sides.

The youngest elephant seal pup returned yesterday morning from her one day adventure in the sea. She spent the whole day sleeping by the wood pile. The oldest pup has been gone for the past two days. A new adult female elephant seal arrived yesterday. She is most likely one of the four mothers that was here in January and February. So far the three have come back a month and a half after they each weaned their pups, which happened on January 21, February 4 and February 9.

At today’s 16:31 high tide, after recording the salinity and temperature of the water, I hooked up the hoses and pump to top up the seawater in the cistern. The gas powered water pump sucks water through a hose with a strainer dropped off the end of the jetty. The water is pumped through 76 m (250′) of fire hose up to the cistern. Over a couple hours, tens of thousands of litres of water were pumped into the underground cistern, which should feed the desalinator for the next month and a bit.

Yesterday, there was one pleasure boat that zoomed through Middle Channel and stopped by the rocks to take photos of sea lions. This afternoon, the Canadian Coast Guard lifeboat Cape Calvert, appeared to be out for a cruise around Race Rocks from the base in Victoria. They came in for a closer look and a couple of the crew appeared to be snapping photos of Race Rocks with their phones. This is a very photogenic place. This afternoon, Guy, Corey and Christine from Pearson College delivered a new fridge and took away the old one that recently stopped working. They also brought some fresh food from the Pearson kitchen, which is closing down for a while.

Here are a few photos from the past two days:

The population of elephant seals is increasing on Race Rocks. The boat ramp, their preferred haul out spot, is getting a lot of traffic. Yesterday morning, an adult female arrived and quickly made her way up to the centre of the island. She could be one of the females who left in January or February, based on her size and scars on her back from mating.

I realized this morning the adult female elephant seal I have been seeing on and off for the past three weeks was in fact the first mother of this winter. In the month the seal and I were both here on this island from December 21 to January 21, I never realized she had two flipper tags. I only ever saw the ones marked T562 on both sides of one of her flippers. This morning I saw two sets of different tags, one on each flipper. Perhaps the mud and snow of the early winter concealed the tags. I also did not have as many opportunities to read the tags when the mother was spending most of here time either nursing her pup or mating with the alpha male.

Now that I know she’s the mother of the male pup, it could explains why that pup came towards her when she first arrived on March 3. The other pups moved away from her. Although, I haven’t seen the male pup interact closely or vocalize with its mother.

A juvenile elephant seal arrived this morning with two green tags, E103 and E135. There is something about today that made all the tags very visible. The seal looks to be very well fed for the upcoming moulting. This seal was here in the fall. She was born and tagged in Ano Nuevo, on the coast of California between San Francisco and Santa Cruz. I haven’t been able to figure when she was born. See the log post from September 30, 2019 for ecoguardian Mara and Kai’s details of the seal they called Eric. A few weeks later, Ecoguardian Laas revealed this seal was a female and named her Erica in the log post from October 11, 2019. Naming the seals can get confusing.

While not all elephant seals are tagged, some are studied for all kinds of factors from movements to genetics to bioaccumulation and generally understanding more about this fascinating species. I am realizing as the seals move around Race Rocks, how difficult it is to tell them apart. The pups are starting to look more alike as they lose the last of their pup fur. It’s a fun game as I try to track their movements as best I can, while I move around the island doing my daily routine.

With the arrivals of seals, there was also a departure today. The youngest seal pup was outside the house last night when I went to turn off the generator and desalinator, but nowhere to be seen this morning. Perhaps she ventured out a little to far from the shallow end of the jetty bay where she has been practicing her swimming. I am curious if she will return, as two months old is a bit young to leave for good. The other two pups are still here.

There were no boats seen in the ecological reserve over the past two days. I heard a solo kayaker by the name of Travis paddled around the islands yesterday.

Here are some photos from the past two days:

March 16 and 17

Wind: yesterday variable 3-13 knots, today mostly E 0-13 knots
Sea State: both days calm
Visibility: both days 15 NM
Sky: both days clear
Temperature: yesterday 3-11 °C, today 4-9 °C
Atmospheric CO2: 414.35 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It’s still officially winter, although it’s looking a lot more springlike. The ground is drying out, after lots of sun and little moisture lately. The elephant seal pups are now fending for themselves, as there are no signs of adults around. The female, tagged T563, hasn’t been seen for three days.

Today marked the first day this winter with more than 12 hours of daylight. The sunrise was at 7:21. The sunset was at 19:23. Each day adds three and a half minutes of light.

The pressure washing continues, in an effort to clean algae off the exterior walls of the buildings. Other maintenance tasks are happening like cleaning the solar panels, chopping wood, keeping the paths clear and running the desalinator. There is still lots of time leftover for watching the seal pups, eagles, pigeon guillemots and learning about this amazing place.

Yesterday, there were two tour boats in the ecological reserve. Today, Pearson College’s boat Second Nature and captain Greg came to deliver fuel for the generator. This afternoon, there was a pleasure craft touring, quite quickly at times,  around the islands. With lots of marine mammals in the water and along the shore, it’s important for people to drive at a slow speed in the ecological reserve.

Elephant Seal Excitement

Wind: yesterday 0-36 knots from W, E, S, W throughout the day, today 9-40 knots from W

Temperature: yesterday 5-9 °C, today 7-10 °C
Atmospheric CO2: 413.72 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The ecological highlights of the past two days were a bald eagle eating a bird and as usual the very entertaining elephant seals.

A new female elephant seal arrived on the main island this morning. She is tagged T563 on tags on each of her tail flippers. I contacted elephant seal researchers to check her history. She was tagged as a pup in the birthing season of 2010-2011, on the Farallon Islands, off the coast of San Francisco. That makes her just over nine years old. She hasn’t been seen by those researchers since. Last year, Ecoguardian Laas spotted her for the first time at Race Rocks on March 21. This morning, the alpha male was attempting to mate with her. Now she is hunkered down by the flagpole, shielded from the strong west wind. The adult males were bellowing at each other for most of the day. The beta male has an advantage of a high lookout point, on the helicopter pad. He has been up there since January without leaving. I am not sure he knows how to get down, as I have seen him attempt a few times before turning around. He must be getting hungry.

The oldest of the two female pups might have gone for a swim yesterday. I saw her with wet fur climbing up the rocks from the east bay.

The youngest female pup and oldest and only male pup have been hanging together, vocalizing with each other and appearing to play fight.

In between watching nature neatos, I did some maintenance around the island. I used a new two metre pressure washer wand to get the algae off the north side of the boat house, tank shed and Race Rocks sign. I hope to clean off the rest of the buildings over the next few weeks, now that the desalinator is pumping lots of freshwater. I also fixed the door on the freshwater shed with a new hasp and a piece of wood to stop the door from blowing inwards.

No boats or visitors were in the ecological reserve over the past two days.

Here are some photos from the past two days:

One Day Old Elephant Seal Pup

Wind: Yesterday 5-15 knots W to N; Today 0-18 knots SW to E
Sea State: up to 1 m chop
Visibility: 10-15 NM
Sky: overcast with light rain this evening
Temperature: 8-9 C
Atmospheric CO2: 412.75 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The one day old elephant seal pup is doing well. It seems to have got the hang of nursing. The alpha male elephant seal, who in the past has been referred to as Bernard, interacted with the pup and mother several times today.

I heard from elephant seal researchers in California that the new mother is T562, who also had a pup on January 4, 2019 on Race Rocks. She was born in the 2010-2011 breeding season on SE Farallon Island, near San Francisco. Until the beginning of 2019, she hadn’t been recorded anywhere since her birth. See Garry Fletcher’s post from February 9th about the elephant seal cow.

Last breeding season, three elephant seal births occurred between January 4 to 20. I will keep a look out for more elephant seal arrivals. Usually, they haul out and then give birth a few days later. Although, the new mother T562 was here for a couple weeks before she gave birth.

The entangled california sea lion is still present on the rocks near the winch and jetty. There has been no sign for the past two days of the entangled steller sea lion.

A previously rescued california sea lion was spotted today and appears to be doing well. More can be read about the care given to that sea lion during the visit by the Marine Mammal Rescue Centre, as detailed in Laas’ post from November 9.

Several eco tour boats have been in the reserve each evening. Yesterday, SCUBA divers were in the water near the North Rocks.

Here is a video of the new elephant seal family:

    • A few boats cruising by today, mostly pleasure crafts and a couple tour boats and even a couple sailboats and kayaks on this beautiful day
    • Greg will also be dropping by this afternoon to bring some water and food

Ecological

  • the tagged elephant seal that the previous ecoguardians named Eric turns out to be an Erica, she is female
  • It is unusual for a juvenile elephant to be sticking around an area for this length of time, typically they would be moving along the coast now
  • There are so many sea lions right now and it seems she does not mind the smell or the noise but it isn’t unusual for elephant seals and sea lions to be hanging out together
