Logs and high water again

The scene at the Jetty this morning was similar to yesterday but with a bit more destruction of electric fence supports and bigger logs straddling the Jetty.  Sadly the emancipated California sea lion didn’t make it through the night and was found with its head hanging in the water in the same place it spent all of yesterday.

The Jetty this morning at high tide with logs and water washing over it. The dead California sea lion is at the top of the boat ramp just ahead of the logs.

 

A gull found it late afternoon and was feeding on the fluids draining from its nostrils.  An hour later it began working at its eyes. It is hard to watch how quickly an animal goes from being a predator to carrion.

 

I thought I would report some good news on sea lions and how their populations have recovered in past 50 years and also on the data for the two branded sea lions observed this month at Race Rocks.

California sea lions have made a great recovery in recent years since the Marine Mammal Protection Act of 1975.  From roughly 18 thousand individuals in 1979, the US population is now stable, last estimated to be over 250,000 in 2014. Abundance in Canada has increased. In 2020-2021 the population size of overwintering sea lions was 13,600 – 3 times more than in 2009-2010. The breeding season population size was 43,200, compared to 39,200 in 2013. Below is a photo and table of observations for the branded California sea lion observed in January 2026.

 

Stellar sea lions were once on the Endangered Species List in the US. It was delisted in 2013 and today the population size is about 52,000 in the US. From aerial surveys in 2016 – 2017 in Canadian waters the breeding season estimate was 43,200 and the overwintering population estimate was 52,700. The figure below shows how many Stellar sea lions were killed in BC!

Below is a photo and table of observations for the branded Stellar sea lion observed in January 2026. In the wild female Stellar sea lions can live to 30 years. Males can live up to 20 years.

Weather

Cloudy skies. Periods of rain. Winds gentle to moderate northerly breeze (The large waves and surges at the Jetty we experienced today were generated in the stronger wind areas to the north and east of here and are a combination of waves and tidal surge). Daytime temperatures 9 to 11 degrees.

Logs and high water

There was too much excitement here this morning. Waves and a high tide brought a ton of logs crashing on the shore, over the Jetty and against the electric fence shattering the wooden supports.

I so wanted to pike pole some of nice logs onto the ramp but the California sea lion on the ramp ahead of the logs wouldn’t allow it. Normally approaching with the herding board will encourage them to move.  The wheelbarrow also normally works. I even tried putting the herding board upright in the wheelbarrow.  It grabbed the wheelbarrow in its mouth, picked it up and flung it over its shoulder toward the sea. That ended my efforts to move it along. I was glad to able to retrieve the wheelbarrow with a pike pole.

The sea lion has been there all day and it doesn’t appear well. It is very skinny, almost skeletal, and appears to have little ability to move its hind end. I expect it may decide to move tomorrow when the students come and it sees a large group of people.

I had to skip the sea water sampling today as it was too sketchy during the morning flood with all the water over the Jetty and crashing logs, and too scary to walk past the sea lion in the dark for the evening flood event. The fences will need to be repaired when the tides drop later in the week and hopefully the good logs aren’t washed away.  I focused on cutting the smaller firewood pieces on the grass that had been hauled up previously.

Weather

Partly cloudy in the morning, overcast with periods of rain in the afternoon. Gentle northerly breeze (Gentle sound pleasant, I suppose on large sail boat,12 to 19 knots may feel gentle and keep the boat moving, but in the rain and cold, there is nothing gentle about it). Daytime temperatures 9 to 11 degrees.

Weather change

Wildlife notes

All is well with the elephant seal pup on day 9.  I hope the pup gets a lot bigger before a male shows up to mate as it will need to be sturdy and move out of the way quickly.  The adult females go into estrus (become receptive) at the end of the nursing, about 24 days after giving birth. She gave birth on the January 20th so she will be receptive around Valentines Day.  They have an 11 month gestation period but the fertilized egg doesn’t implant in uterine wall for a few months. This gives mom time to fatten up again before she comes back to land in the spring to molt.  After nursing, molting is her next biggest energy draw, as she also fasts during this event. The fertilized egg will implant in June or July, giving the pup fetus 7 months to develop.

On this first drizzly and partly grey day in a long time I’m sharing an image of a Harlequin duck in the sun on East Beach that I took a few day ago.

Facility work

  • battery fluid top up

Pumping salt water

Wildlife notes

The elephant seal family is content in the hollow. The pup is growing and the mom is determined to keep the birds away from the placenta and has large blood stains from rolling in it.

Mother and pup on Day 8. The red stains are from rolling in the placenta, seen on the far right.

A couple dunlins, a sanderling, a surf bird and several black turnstones were feeding at the low tide on the north shore.  They are all roughly the same size but with different colourings and beak shapes – shame I didn’t have the time to observe if they were targeting different things to eat.

Facility work

The focus of today was filling the cistern with salt water as we need a huge reservoir of salt water. The ratio varies a bit but for every 1.5L of fresh water produced, about 9L of concentrated salt water is sent back to the sea (for pictures of the desalination plant see 26 | July | 2024 | Race Rocks Ecological Reserve-).  Here are some photos of the fire hoses and pump setup we use to get salt water up to the massive rock and concrete cistern beside the Keeper’s house. It took many hours and 3.5 tanks of gas on the pump.

Pump tied down on the Jetty. The green intake hose on the right is lowered into the ocean and the pink hose sends the salt water up to the cistern.

Day 7

Wildlife notes

The elephant seal pup is a week old today. It is putting on weight, rounding out a bit and getting stronger.  At two weeks old they should double in size from when they were born.  Some gulls finally had a few stabs at the placenta but the mom does not tolerate them nearby.

Struck gold

Wildlife notes

The pup slept up close to its mom on this cold winter day.  There was frost on the ground and it was 3 degrees most of the morning. I even pulled out the big guns… my heavy weight merino long johns, normally reserved for winter sailing. I turn the furnace on for 10 minutes in the morning and have the woodstove going all day.  The house cools down a lot over night and it is really hard to get out of down bag in the morning.

A group of about 30 pigeon guillemots were feeding in the current north of the Jetty. I had never seen them in their winter plumage so it took quite a while observing, photographing and freezing my fingers before I saw their tell-tail orange feet.

Facility work

I had fun with the chainsaw today making a piles of sticks in the grass but it was down on the beach by the boat ramp where I struck gold. I cut up a yellow-cedar and Douglas-fir log. Too bad the yellow-cedar wasn’t a bigger log as it burns so hot.  Poseidon please bring us more yellow-cedar!

  • topped up battery fluids
  • transferred fuel

Wildlife notes

It has been a peaceful day here.  The skies clear and waters calm. The elephant seal and her 5 day-old pup are sleeping and nursing in the sunny hollow.  The pup is strong enough now to hold its head high and reach the upper teat. Two branded sea lions were photographed and reported to NOAA.

Day 4

The pup has shed its umbilical cord. It is feeding well and spends time squirming around, stretching, rolling and exploring its flippers and scratching. The placenta is still intact. I watched a raven show some interest but mom sent it off with a big bellow.

It was another glorious day. Today I’ve posted some photos of the scenery and other inhabitants, not just the elephant seals on this fine sunny day.
