A Third Elephant Seal Pup is Born

Overnight a third elephant seal pup was born to the mother who arrived at Race Rocks on Monday, January 6. On the lawn in front of the house, there are now three pups hanging out with their mothers, a pregnant female and the alpha male.

Sea Otter Visit and Snow Day

Wind: yesterday 3-53 knots W, today 9-34 knots N
Sea State: yesterday 2 m waves from W, today up to 1 m waves from N
Visibility: yesterday 2 to 10 NM, today 1 to 2 NM
Sky: yesterday sunny with cloudy patches, today fog and snow
Temperature: yesterday 7 to -1 °C, today -1 to -4 °C with windchill as low as -14 °C
Atmospheric CO2: 413.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday brought many gifts from the sun: rainbows, warmth and solar power for the batteries. In the afternoon, I spotted an unusual sight for this time of year. A sea otter was being tossed around in the waves near the jetty. I grabbed the camera and did my best to capture some photos as it swam around the northeast side of the island, got out briefly on the rocks near the house, then swam back to the waves of the north side, before it floated northeast past the east side of the North Rocks. The wind was over 40 knots, which made it hard to hold the camera steady and take photos. I managed to get a few photos (see below) that show a slightly blurry sea otter in action.

Last night, the temperature dipped below O °C. I prepared the buildings from getting too cold by turning on heat in the evening. Throughout the night, the fog horn sounded and the snow accumulated. Judging by the snow on the relatively sheltered ground mounted solar panels, there was about 8 cm of snow overnight and into the early afternoon. On the rest of the island, the tracks of sea lions, birds and slide marks of elephant seals showed the few movements of a quiet island. A smaller than usual group of gulls and cormorants were hunkered down on the southwest side of the island. Most of the sea lions were rafting in the water, which was observed this afternoon at 7.7 °C, much warmer than the -4 °C air temperature.

Another Elephant Seal Birth

Wind: yesterday 2-19 knots NE, today 1-46 knots NE shifting to W
Sea State: yesterday 3 m waves from NE, today 2 m waves from W
Visibility: 10 NM
Sky: both days overcast with patches of sun and rain
Temperature: 6-8 °C
Atmospheric CO2: 413.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday morning in the rain, I started pressure washing the slime covered stairs up to the door of the lighthouse. They were getting a bit treacherous on a wet and windy day. A second tank of water later, it was sunny and the 18 stairs as well as entryway were clean.

The past two nights have been louder than usual, with the elephant seal bellows and barks dominating the soundscape of waves, wind and sea lion barks. I was surprised to not see a new pup yesterday morning, after all the carrying on outside my windows all night. This morning, the light brought a delightful sight of a new pup. Once again, the eagles, black turnstones and gulls all made quick work of getting rid of the placenta and umbilical cord. The new mother had arrived at Race Rocks on January 3. The other pup looks huge compared the new pup. It’s amazing how much weight the older pup has gained in two weeks. The three females appeared to be at odds with each other for most of the day, with lots of bellowing and chomping. If the remaining pregnant female sticks to the pattern, she should give birth on Tuesday, which is nine days after she arrived on the island.

See the photos and videos below for some sights and sounds of the past two days.

Weekly Census

Wind: yesterday 15-46 knots W, today 3-14 knots W shifting clockwise around to S
Sea State: yesterday up to 2 m waves, today rippled water
Visibility: 10 NM
Sky: yesterday overcast, today mainly sunny
Temperature: yesterday 6-7 °C, today 3-5 °C
Atmospheric CO2: 413.56 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The last two days were spent doing some tasks around the island like running the desalinator, topping up the batteries with the generator and cleaning. Today, the sun in the morning and early afternoon was taken advantage of to get a great view of all the species for the weekly census and do a solar powered load of laundry.

The only visitor was Greg, who came out from the college this afternoon for an hour to show me how to use some equipment and remove a load garbage from the island. No other boats were seen in the ecological reserve.

I am glad to hear the Race Rocks live video cameras are being used by the grade 10 students in the Trek Outdoor Education Program, in Vancouver.

New Desalinator and New Adult Female Elephant Seal

Wind: 1-44 knots from NE yesterday to W this evening as the wind increased
Sea State: up to 3 m waves breaking on west side of the island
Visibility: 5-10 NM
Sky: overcast with rain and a few sunny patches today
Temperature: 6-11 °C
Atmospheric CO2: 413.70 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It was a flurry of activity on the island yesterday. A big change from having no human visitors for a week and a half. Greg brought seven other people on the boat Second Nature. Three volunteers from the college (Lawrence, Sandra and Vincent) came to help with some maintenance and clean up tasks. John and Mike, from Pacific Coast Fire Equipment, were here to do the yearly inspection of the fire extinguishers. Warren and Ric spent almost six hours doing the electrical and plumbing hook ups and tests of the new desalinator. The desalinator room is very cramped quarters with thick concrete walls and only a six foot high ceiling inside. As Race Rocks legend goes, the building was originally constructed as a fallout shelter for Cold War fears of nuclear attack. It apparently contained emergency supplies and two bunks for the lighthouse keeper and assistant keeper. There was no space for their families. In 1975, the building was converted to a water filtration plant.

The non-human activity was busy too, with the arrival of a new adult female elephant seal. She showed up soon after the boat, staying on the boat ramp for a while before coming up to the middle of the island. The alpha male chased her around, they barked a lot, then she settled in the grassy area between the desalinator shed and the flagpole, where she still is this evening. Now there are two suspected pregnant seals hanging out in the centre of the island near the mother, pup and alpha male. The two other males appear to be keeping their distance. One is near the jetty. The other is behind the house by the compost bins.

The desalinator is running well after a total of nine hours of use. This evening, I was delighted to see that it had pumped 600 L of fresh water into the tank. Combined with the 500 L from yesterday, the desalinator has produced more fresh water than has been used since my shift began on December 21. At this rate, the 4,500 L fresh water tank should be filled up in about a week. At that point, the desalinator will be run regularly, but for shorter amounts of time. It’s an energy intensive way to produce water which consists of a reverse osmosis system and secondary UV filter. The temporary method of getting fresh water while the desalinator was out of commission was also very energy intensive. It consisted of filling up a 1,000 fresh water tank at the college, boating it to the island, and pumping it up to the tank from the boat. The water usage is planned to increase a little bit in the near future, due to some much needed pressure washing of the exteriors of the buildings, to prevent them from being overtaken by algae.

First Weekly Census of the Decade

Wind: 5-21 knots N-NE
Sea State: up to 3 m waves
Visibility: 10 NM
Sky: overcast with rain
Temperature:5-11 C
Atmospheric CO2: 412.64 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The weekly census was done today, because the rain yesterday created poor visibility. This morning, it was overcast but not raining, so there was a good birds-eye view from the top of the lighthouse. Some species that were not last week are a whimbrel, snow bunting and another female elephant seal. The new seal looks pregnant, so there might be another pup very soon. She has moved into a spot on the grass between the desalinator building and the flagpole. That’s a great place for me to watch from the house, which is just 20m away. Last year, the three pups were born between January 4 and January 20.

I heard back from a sea lion researcher about the branded sea lions that were seen on Race Rocks a two days ago. Bryan, from the Oregon Department of Fish and Wildlife, let me know about some of the places where the sea lions have been:
California X282: branded at Astoria (Oregon) on Feb 25, 2016 and resighted in Oregon and at San Miguel Island, CA in 2016-2017.
California X392: branded at Astoria on March 8, 2016 and resighted in Oregon and at San Miguel Island in 2016.
California X501: branded at Astoria on May 24, 2016 and resighted in Oregon fall of 2016.
California 1-59: braded at Bonneville Dam (near Portland, Oregon on the Columbia River)on May 19, 2015 and resighted at Astoria and Bonneville through 2017.

The only boats seen in the ecological reserve were two eco tour boats and two kayakers.

Blowing a Hooley

Wind: Yesterday 5-35 knots N to W; Today 25-35 knots W with gust of 44 knots
Sea State: up to 2.5 m waves
Visibility: 5-10 NM
Sky: overcast with clear patches today
Temperature: 7-12 C
Atmospheric CO2: 413.20 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The forecasted gale warning materialized right on time on Tuesday evening. Overnight and throughout today, the westerly winds were between 25 to 35 knots with gusts as strong as 44 knots. There are lots of whistles and creaks in the 1960’s house. The storm also showed a few leaks in the various outbuildings. The strong winds brought clear skies and slightly warmer temperatures. For most of the day, rainbows were visible to the north, between Rocky Point and Victoria.

Yesterday, even though it was stormy, several hours were spent working outside on various maintenance and month end tasks around the island, which was made easier due to the animals and birds being less spread out as they hunkered down out of the wind.

Today, four branded sea lions were recorded and reported to researchers, who study sea lion ranges and lifespans.

The island’s population of elephant seals is currently at seven. One recently came back from a solo retreat on the West Rocks. The four non dominant males appear to be keeping their distance from each other at cardinal points of the island. The alpha male is hanging out in the middle of the island with the mother and pup. This morning, two of the beta males had fresh wounds on their backs, suggesting a possible disagreement with each other overnight. The elephant seal pup is continuing to nurse. Pups gain a whopping 4.5 kg per day from their 35 kg birth weight. Between all those pounds the pup is packing on and the rain, no wonder its coat is looking less wrinkled.

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:

Elephant Seal Pup

At some point overnight, an elephant seal was born. The pup is moving around and appears be trying to figure out how to nurse.
