Visitors:
Greg and Bruce visited this afternoon to deliver 1,400 L of freshwater and a new first aid kit.

Maintenance:
I did the routine tasks of cleaning the solar panels and house windows, topping up the water in the 24 deep cycle batteries, fixing the electric fence, tidying, and maintaining the freshwater system.

Ecological notes:
There have been a lot of humpback whale activity over the past few days to the west, south, and east of Race Rocks. The whale watching boats have been active in the area. From what I hear on the VHF radio, they have been very pleased with the humpback viewing. I have not seen any whales swim through the ecological reserve.

I heard back about the tagged elephant seal, from the researcher at Año Nuevo Natural Reserve, in California. The juvenile seal, tagged H999 and K646, is a male who was born in January 2022. He was previously observed here and reported to the researchers on April 1, 2023. He has been moulting here for at least the past several weeks. He appears to be almost complete the moulting process, so he might be moving on soon to feed in the deep waters.

Weekly Census observed on July 13:
elephant seal: 1 juvenile (tagged H999, K646)
Steller sea lion: 3
harbour seal: 79
bald eagle: 2 adults, 1 juvenile

Back on the Rocks!

I am back on Race Rocks for the next two weeks, having been away since August. Greg drove me out yesterday afternoon in the boat Second Nature, arriving at 15:30. After unloading my gear and food, I reacquainted myself with the island’s building, systems, and other species.

There are two elephant seals on the island. One sub adult hauled out on the boat ramp has two green hind flipper tags labelled H999 and K646. They mentioned by Derek on the April 1, 2023 census: https://racerocks.ca/animal-census-31/. Green tags usually signify the seal was tagged as a pup at Ano Nuevo Reserve, near Santa Cruz, California. I have put in a request with the researchers there to find out about the sighting history of the seal. The other seal here right now is a female adult, who has been hauled out near the bushes on the centre of the island and made some trips to the water, was probably one of the mothers from the winter breeding season.

The most populous birds right now are the few hundred nesting glaucous-winged gulls and chicks. There are still many nests with eggs yet to hatch. The pigeon guillemots are active in a few places around the island: near the jetty, blasted rocks north and west of the helicopter pad, and the south side of the island. I have yet to see any oystercatcher chicks or the barn swallows that have been seen recently.

Weather for July 7 afternoon and evening:
Wind: W 32 knots
Visibility: 15 NM
Sky: Clear
Sea: 3′ chop
Air temperature: 14 C

Weather for July 8:
Wind: W between 10 and 31 knots
Visibility: 10-15 NM
Sky: Partly Cloudy
Sea: rippled in morning, up to 3′ chop in afternoon
Air temperature: 12-15 C

I gave the solar panels a good scrub this morning to get off the built up gull guano. I have also been monitoring the freshwater levels after a couple recent leaks that have been fixed.

Here are some photos from the past two days:

Census July 6

Ecological Notes:

  • I am seeing more gull chicks everyday. Many gull parents are frequently feeding their two or three chicks.
  • I seem to have come to an understanding with some gulls. If I approach near them on the path at a slow speed, we both ignore each other. There are other gulls who freak out if I even look in their direction. As I do necessary work, I limit my movements around the island and avoid certain paths that have nearby nests and chicks.
  • See photo gallery and captions for more details on the ecological happenings over the past two days.

August 16 – Returning Sea Lions

Wind: from NE in morning, SE in afternoon, W in evening – between 2 to16 knots
Sea State: calm in morning and rippled in afternoon
Visibility: 15 NM
Sky: clear
Temperature: 16-25 °C
Atmospheric CO2: 412.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

While I have only provided the conditions for today, I did step onto the Rock just after noon yesterday. It’s great to be back, having spent the whole winter and the first few weeks of spring here. I will be here for the next two and a half weeks, 100 days shorter than my last stint.

I feel very fortunate to be a part of the amazing team of Pearson students, alumni, staff, volunteers, donors and researchers who keep this Ecological Reserve going.

I spent yesterday afternoon and evening reacquainting myself with this wonderful place, practicing how to avoid disturbing the young gulls, who blend in well with the rocks as they like to hide beside the paths and in plants.

This weekend, there have been a lot of boats (pleasure craft and eco tour boats) taking advantage of the nice weather. The only visitor to the island, other than me, was Greg, who drove me out here from Pearson and brought back Mara and Kai.

In the previous log post, on August 13, a branded sea lion with an attached flasher (fishing lure) was mentioned. The steller sea lion is branded O-19. Bryan Wright, the Marine Mammal Biometrician/Project Leader at the Oregon Department of Fish and Wildlife, gave us an update on the history of the stellar sea lion:

He was captured and branded by us (ODFW, along with WDFW) at Bonneville Dam on the Columbia River on February 2, 2012.  We don’t know his exact age but he was probably 5-7 years old at the time of capture, making him 12-15 now.  He then wasn’t seen again until July 21, 2016, at Tatoosh Island off the tip of the Olympic Peninsula in Washington.  He was then next seen back at Bonneville Dam from August-November, 2019.

Bryan also passed along an interesting article that was just published called “California Sea Lion (Zalophus Californianus) Monitoring In The Lower Columbia River, 1997–2018” (Brown et al 2020). Click here to read the abstract of the article.

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.

A video of the two beta male elephant seals fighting at the base of the lighthouse. They move very fast when they are motivated. After they disappeared behind the tower, they chased each other around the island and into the water by the jetty, causing a stampede of some nearby sea lions.

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.

Festivus

Wind: 5-19 knots NE
Sea State: up to 1 m chop
Visibility: 15+ NM
Sky: 50% cloud cover with sunny patches throughout the days
Temperature: between 6 and 8 C
Atmospheric CO2: 411.99 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It has been mostly quiet on the rock for the past two days, with the exception of the sea lions barking nonstop. It’s a mystery to me what they carry on about all night. Although, I will take that any night over the fog horn or the urban noises that are too far away for me to hear. The only visitors to the reserve were a few eco tour boats that lingered offshore in the late afternoons.

I had to quickly jump into action this morning, when I realized power had gone out just before I got out of bed. I ran the generator for several hours to make sure the batteries were fully charged. The solar panels helped a bit today, soaking up 3.7kWh of energy, which is a couple hours worth of the energy used on the island. There is lots of learning about off grid living.

Yesterday one of the juvenile males elephant seals left, bringing the population of elephant seals on the island from six to five.

A parcel of about 20 oystercatchers have been hanging out on the south side of the island. They mostly huddle on one leg with their beaks tucked into a wing.

The northeast winds have delivered presents in the form of free firewood to heat the ecoguardian’s house. Through some clumsy use of a pike pole and the tolerance of a nearby resting elephant seal, I managed to land a 6.5 metre log and drag it up the jetty ramp. I also gathered lots of smaller pieces. The wood will be left out in the rain for a while to wash off the salt, then chopped up into manageable pieces, and eventually put away to dry for next winter.
