This is my last log post, as I am heading home tomorrow. This evening, I am packing my things and tidying the house for the next ecoguardian.

I have enjoyed my time at Race Rocks over the past three weeks, as well as my many shifts since 2014 and visits since 2012. Over those years, I have been the resident ecoguardian here for varying shifts of two weeks to four months, during every season and all months except June. There have been so many special moments to witness such as watching storms, elephant seal pups, moulting elephant seal, sea otters, orcas, humpbacks, pelicans, as well as learning how to run the off grid systems. I would also like to think that I have done some work around the island to contribute to things not falling apart.

I plan to pursue other adventures next summer. When I visit Pearson at some point in the future, I hope to hop on a boat for a reminder of the familiar sights, sounds, and strong smells of Race Rocks. In the meantime, I look forward to following along with the log and checking out the webcams every once in a while.

Thank you to the staff team at Pearson College who keep this place running so well (despite the best efforts of the harsh elements) and have let me come back to spend more time on this unique island. I am truly honoured to be a part of the long list of ecoguardians, students, faculty, staff, volunteers, and lighthouse keepers who have stewarded this ecological reserve since its inception in March 1980.

Wildlife Notes:

  • On my last full day here, I was treated to seeing two Bigg’s killer whales (AKA transient orcas) pass very close to me this afternoon. I was talking to a colleague on the phone when I saw the orcas passing east through the channel in front of the house. They then swam around the island where I saw them pass through the South Channel (about 50m from the back porch) between the South Islands and South Seal Rocks. Right after I snapped a few photos of them, a heavy fog rolled in obscuring the whole island.
  • I heard back about the resighting history of the Steller sea lion branded 460Y that I saw on August 13. I spotted him again today hauled out on the South Seal Rocks.
    Bryan, a biometrician from the Oregon Department of Fish and Wildlife, sent me this full history of this 12 year old Steller sea lion:

Resight history for Steller sea lion branded 460Y

Facility work:

  • Clean the solar panels
  • Tidy the house and put away all the tools I moved around to different buildings
  • Fix sections of the electrical fence between the house and tower. I had been avoiding that section due to the gull chicks and my dislike of getting pooped on by protective gull parents. Now, many of the chicks have flown away so the area is easier to access. I will fix the last part by the tower tomorrow morning and hopefully come away unscathed.

Facility work:

  • Clean the 44 solar panels
  • Check the electrical systems on the station boat
  • General tidying around the island’s buildings

Vessels:

  •  Ecotourism: 19
  •  Private: 5

I will contact NOAA and DFO to report the resighting of the California sea lion with the tag 13-2. The orange tags mean the sea lion was rehabilitated. The tag on the left flipper means the sea lion is a male. I will update the log when I hear back about his history. The rest of the California and Steller sea lions are currently hauled out on Middle Rocks. Perhaps this guy needs a break from the frat party.

Facility work:

  • Clean solar panels
  • Check guest house for supplies and cleanliness

Vessels:

  •  Ecotourism: 12
  •  Private: 3

Weather:

  • Sea: rippled in morning, up to 3′ chop in afternoon/evening

Chaos and Creatures!

Today was so action packed I’m not even sure where to begin!

I woke up just after sunrise as I knew today was going to be busy and I wanted to get a few tasks out of the way. At 6am it was already warm out with barely a breeze. The ocean was glassy as I cleaned the solar panels – which were yet again decorated by the birds.

Around 8:30am the first group of Pearson students were dropped off for their marine science exam which was taking place here at Race Rocks. By 9am we had 46 humans on the island which is a lot after not seeing anyone for a whole week. Today’s tide was one of the lowest I’ve seen since being here and its neat to see the rocks and small islands that are usually well below the surface.

Halfway through the exam we had a surprise visit from Coast Guard via helicopter to continue working on the fog horn. Thankfully all of the students were safely tucked away working on their exams down in the tide pools when it arrived. This time they had a smaller helicopter so they actually landed on the grass next to the tower rather than the helipad. Overall disturbance was limited aside from birds leaving the area (but immediately returning) and the minor panic exhibited by me. 

If that wasn’t excitement enough, we saw 3 passing transient killer whales shortly after! Once again, they were quite far in the distance but always nice to see. One of these days I’ll see them up close!

On return to the school, one of the boats found a deceased harbour porpoise floating on the surface. I reported this to DFO and the animal was collected and brought back to the college where it can be stored in a freezer until the DFO team and veterinary pathologist are able to perform a necropsy.

The afternoon slowed down once it was just me and the animals alone on site. Ollie was relaxing in the kelp beds, the sea lions were quiet, and the sun was toasty. I ventured down to the rocks behind the student house to soak up some sun when something shiny caught my eye. Partially sticking out in the dirt I picked up what originally looked like some sort of bivalve or calcified shell, almost something you’d expect to see on a tropical beach. Upon picking it up I realized how heavy it was and that it actually appeared to be man made, with grooves that seemed as though they would hold rope or line. My next guess was that it was a lead fishing weight of some sort or maybe a piece of similar equipment. I rinsed it off and sent some photos to colleagues to further inquire. One of the other Eco Guardians, Derek, helped me to ID it as an “open-end strain insulator” and it supports guy wires/cables by working under compression. Through a page on the Maine Historical Society website I was also able to learn that this porcelain egg like tool was made in 1900. How wild is that! I know this island holds more history than I’ll ever know, but never did I think I’d stumble across a little piece of it among the dirt and the goose poop. I’m going to have a read through some books here tonight and see if there are any photos or mention of it!

Wow, okay I think that is everything for today! Race Rocks will never cease to amaze me.

…I guess I spoke/posted too soon! Shortly after publishing this blog post I spotted a brown pelican circling the reserve and figured it deserved a mention!

Sunshine and a Sea Otter

Posted on by

Today was the warmest, most beautiful day I’ve had yet! Clear blue sky, glassy calm water, and barely a breeze in the air.

As I took my morning coffee for a walk around the site I quickly found Ollie wrapped up in the kelp bed behind the student house. I crept down to the rocks, careful not to wake him and spent close to an hour watching him float in the sun, occasionally rubbing his fluffy little face. This is the closest Ollie encounter I’ve had so far and it was a great way to start my day.

When the weather is this nice you never want to go inside so I decided to tackle my outdoor to do list (see below for facility work). I took a few breaks to check on Ollie and he was in the same spot wrapped up in the same kelp until 5pm when I finally went inside. I saw a few porpoises from the kitchen window as I made dinner which was a nice surprise. Harbour porpoises are tiny and barely make a blip in the waters surface, so days like today are the only days I really get a chance to see them.

I was hoping to capture Ollie at sunset but of course he had moved on by the time I went back outside. I checked on the other animals around the main island and just as I got to the jetty guess who I found? Ollie again right off the rocks and swimming like he was a man on a mission! Considering adult sea otters eat a quarter of their body weight in food a day I was surprised I didn’t see him with any urchins or other snacks today.

In other animal news, one of the female elephant seals has a green flipper tag so I reached out to some contacts for further information. I was able to learn that she was tagged in 2023 in Año Nuevo, California! This is the first time that she has been sighted since then and the researchers were thrilled to hear she survived her first year. How cool!

This girl travelled nearly 1,500km to get here!

 

Facility Work:

Scrubbed solar panels – today is day 3 of not using the generator because we’ve had so much sun! It’s crucial to keep them clean and poop free so we can get the most out of them.

Weeding: greenery grows fast here including weeds. I spent a bit of time clearing out some areas that were growing back.

 

Wood pile: the firewood pile has taken over the majority of the area by the path so I attempted to organize the chaos for a few reasons. I wanted to clear the walking area for both humans and elephant seals, I also wanted to sort out which wood should be used first, if at all. I really had to brave my arachnophobia for this project but I survived! This should hopefully give the wood a chance to dry out better too, now that its not one giant pile.

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!

Posted on by

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.

  • Black oystercatchers: 10 (8 adults, 2 chicks – probably more that are camouflaged)
  • Cormorant: 2
  • Glaucous-winged gulls nesting: 172
  • Glaucous-winged gull chicks: approximately 50 (also hard to spot in the grass and under their parents)
  • Gulls not nesting (some glaucous-winged and some other species) on the south end of the island and outer islands: 97
  • Pigeon guillemots: 123
  • Surfbirds: 3

August 16 – Returning Sea Lions

Posted on by

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

Posted on by

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.
