One more time!  I’m back on Race Rocks for a short shift of just a few days. The last time I was relief ecoguardian was in 2023, and while much remains the same, there have been some changes, too. Nick left the house in great shape. What a nice welcome back!

I got my first trip on the new Pearson College boat. She’s a beauty! With lots of interior seating, I’m sure the students and visitors will appreciate the comfort of future journeys. We came across with several guests including Alex Fletcher, a former long-term ecoguardian on the Rocks.

After a quick look around, tasks began right away with the scheduled water temperature and salinity tests that are taken from the end of the jetty. No problem with the sea lions today as the boat was tied up and keeping them at bay.

One of the major chores for the ecoguardian is keeping the solar panels and building windows clean. Strong west winds this week resulted in the pelting of the Science Building. I know where I’ll be spending some time tomorrow!

As the Pedder Explorer departed, Greg yelled back to me about an entangled sea lion. A female Steller’s had the tell-tale signs of something wrapped around her neck. A close inspection of the photos showed a packing band which must have been on her for years given how far it has cut into her neck. The incident was reported to DFO. If she stays around, they may make an attempt to rescue her and remove the band.

Facility work:

  • Reset the electric fencing on the jetty. Despite Nick’s efforts, the sea lions had knocked several posts off the jetty.
  • Inspected the fence line around the perimeter. Again, the sea lions are not respecting the barrier.

Weather:

  • Beautiful and clear on arrival at approximately 2 pm.
  • Wind: Variable 2-13 knots
  • Sea: rippled
  • Air temperature: low 14 °C, high 25 °C
  • Seawater temperature at max flood: 10.7 °C

Wildlife Notes:

  • This morning, I enjoyed watching from the top of the lighthouse as a Steller sea lion feasted on a salmon. See the photos below.
  • I caught a glimpse of four brown pelicans flying through the ecological reserve and stopping in the kelp bed near Turbine Rock. I did see one close up this afternoon. They are my favourite bird I get to see here due to their size and rarity in these waters.
  • With the permission of DFO (Department of Fisheries and Oceans), the dead Steller sea lion was towed away. The Race Rocks team did not want the carcass to rot in the jetty bay where it hauled out and died on Thursday. The plan was for the dead sea lion to be towed back to Pearson College, so it could be dissected by the Marine Science students. Due to the decomposition, the tow did not work and the carcass was cut loose in deeper water on the east side of the ecological reserve. Now that it has sunk, it is part of the food web.

Facility work:

  • Due to rust, the jetty railing at the top of the built in ladder was removed. A new one will be manufactured and brought out soon. I reconfigured the electric fence at the end of the jetty to ward off the sea lions. After all, they do have so many rocks they can use.
  • This afternoon, I took the Race Rocks station boat out for a leisurely tour around the ecological reserve. The boat ran well. I tested everything a couple weeks ago and was waiting for a good tide and current combination to take it out beyond the jetty. My attempt on Thursday was thwarted when the dead sea lion was blocking the boat ramp. Today, I enjoyed seeing the various smaller islands around the ecological reserve and vantages that I do not often see from Great Race Rocks.

Wildlife Notes:

  • The dead Steller sea lion is still in the jetty bay and untouched by scavengers. The tide last night did flip it over and move it slightly away from the boat ramp.

Facility work:

  • The generator ran automatically this morning from midnight to 08:00 because the state of charge dipped to 66%. This afternoon, the solar energy kept the battery topped up.

  • The dead steller sea lion spotted yesterday was still on the boat ramp this morning. So far it appears to have been untouched by any scavengers. With the permission of DFO, there is a plan in the works to remove the animal from boat ramp in a few days if the high tide does not get to it first.

Facility work:

  • The generator turned on automatically at 10:00 due to not getting enough solar energy for a full charge yesterday. It ran for almost seven hours before turning off with a charge of 94%. I could not figure out why the system decided it did not need a full charge like usual.
  • I cleaned the solar panels with most of the work already done by the rain.

  •  Ecotourism: 3

  • A couple of humpback whales passed through the northern and eastern side of the ecological reserve this afternoon. At 14:30, I saw a spout just beyond the North Rocks and watched as the whales swam south. I heard over the radio from the ecotour boats that there appeared to be a mother and calf. I was surprised to see several sea lions swimming around the humpbacks. Most likely the sea lions were feeding on the fish that were being stirred up by the big whales.
  • Early this afternoon, I noticed a Steller sea lion that had hauled out on the boat ramp beside the jetty. The sea lion did not move when I walked near it several times to fix the electric fence at the end of the jetty. It also wasn’t breathing, so I suspected it had died at some point overnight or this morning. I checked on it at this evening’s high tide at 19:30, by which point the sea lion’s mouth and nose were just under the water, but there didn’t appear to be enough tide to take it out. I reported it to the DFO (Department of Fisheries and Oceans) BC Marine Mammal Response Network, in case they want to check it out. Fortunately, I did not notice any signs of trauma on the animal from what I could see on the top. It had some battle scars on its back like most of the male sea lions and elephant seals I see. I am fairly sure it’s a male that is not mature, based on the thicker neck but not bulk of the fully mature males.

Facility work:

  • Fix parts of the electric fence that were breached by party animal California sea lions. One made a foul mess at the end of the jetty that I washed away with many buckets of sea water. Any excuse to use a bucket on a rope to pull up seawater.

This morning, I spotted a Steller sea lion on the north side of the island that had a brand 460Y. This sea lion was branded 12 years ago as a pup in July 2013 in Rogue Reef, off the southern coast of Oregon. I have read that sea lions live between 20 to 30 years. I submitted the resighting to the researchers at the Oregon Department of Fish and Wildlife. Check out this log post by Anne Stewart from April 2015, when this sea lion was last recorded at Race Rocks.

Facility work:

  • Check and top up the water in the 24 batteries

  • Wind: west 19-39 knots
  • Sea: up to 3′ moderate

Wildlife Notes:

The sea lions are spreading out more on the main island. So far they are resting on the shoreline rocks and staying off the jetty and paths. If only the gulls would be as open to sharing the space. There are a few gulls that are for some reason getting even more territorial near the intersection of the paths in the centre of the island. Maybe they are getting tired of protecting their chicks for so long. Unlike the eagles that fly over the island and cause panic, I come in peace. I am still holding a broomstick over my head as I walk on the paths, so the gulls have a harder time dive bombing me. Perhaps the broomstick does not show peace to them.

Facility work:

  • Swept the rest of the stairs in the lighthouse. The thick stone walls make it a cool place to be in the afternoon heat.
  • Maintained the electric fence around the jetty to dissuade the California sea lions from taking it over.

Vessels:

  •  Ecotourism: 15
  •  Private: 7 (including 3 sea kayakers)

Weather:

  • Sky: clear
  • Wind: variable 4-15 knots
  • Sea: rippled
  • Air temperature: low 14 °C, high 30 °C (And I thought yesterday’s monthly high of 21 °C was hot!)
  • Seawater temperature at max flood: 11.9 °C

  • Many of the gull chicks and adult gulls were panting in the middle of the day, due to the high (for Race Rocks standards) heat reaching 21 °C. The low wind and clear sky helped crank the heat.

  • Tidying the top of the lighthouse tower and sweeping the stairs

Vessels:

  •  Ecotourism: 16
  •  Private: 8

Weather:

  • Sky: Clear
