This morning, I heard a ruckus outside the west side of the house, where the a few of the elephant seals have been hanging out. The largest male appeared to be fighting the small juvenile male, while the female watched. The adult was slamming its head down onto the juvenile and biting it. This lasted for a few minutes before the juvenile and female fled to the north side of the path.

While I was doing the census in the middle of the day, there were three people snorkelling off the southwest of Great Race Rock Island. They took turns snorkelling in pairs, while one person stayed in the boat. Six other pleasure craft and eco tour boats were seen in the reserve over the past two days.

Yesterday, Laas’ shift ended after being on Race Rocks for the past two and half months and a big chunk of the past two and a half years. I came out to the island at noon on Second Nature with Guy, Corey, two students, a family visiting the college and a friend of Laas. It was great to share in the excitement of all on the boat. I also appreciated their help carrying my many bins of food. I always get excited when the boat rounds the corner out of Pedder Bay and the lighthouse comes into view. The cacuphony of seal lion barks and belches was overwhelming when the boat pulled up to the jetty. Thanks for the great welcome home, my pinniped pals. I had a run through of the energy systems with Laas, Guy and Corey, as the equipment has changed completely since I was here almost five years ago. It’s great to be back on the Rock. Thank you Laas for leaving the place so tidy. Best of luck on your new adventures.

After the group left, I climbed the 99 steps inside the lighthouse to get a bird’s-eye view of the island. I spend the rest of the day reacquainting myself with the place and unpacking. I welcomed the slow down, as I settled into the island that I will call home for the season, watching the changes as the days become longer. I will be here for all of winter and depart soon after the vernal equinox.

Today, I continued to check out more places and do the regular tasks like monitor the energy levels, wash the solar panels, turn the composting toilet and sample the salinity and temperature of the water at high tide. On one trip up the lighthouse, I counted 336 sea lions on the rocks. There are also six elephant seals on the main island: three large males spaced apart from each other, one pregnant looking female in the centre of the island and two juvenile males.

Little Steller

Weather: 

  • Visibility: 15+ miles
  • Sky: overcast
  • Wind: 15-20 kn NW
  • Water: Little choppy under 1 foot

Visitors/Boats: 

  • Since I got back on Tuesday there have been approximately 15 boats per day, the number varies a bit each day
  • On tuesday and thursday we had visitors from the eagle wing crew come for a tour on Race Rocks. It was so nice for them to be able to come check out what Race Rocks looks like from the land after seeing it from the water so many times
  • Greg and Guy are coming by today so we can do a more in depth orientation on the projects and maintenance going on around the island

Ecological

  • After my walk around I noticed a couple interesting things, first there was a young steller, not a baby but he was still nursing.
  • Then an elephant seal, which was so nice to see and it had a green tag on it. Unfortunately by the time I got my camera it was already gone.
  • There have also been humpbacks nearby lately, the past two days there have been 4. Yesterday when the eagle wing crew was here was saw a fishing boat getting way to close to the whales, the whales were clearly upset and one jumped right out of the water because of it. Luckily we saw one of the whale watching boats from BC tours and got a hold of them and they let us know they had a word with the fishing boat about keeping its distance from the animals.

Maintenance

  • The fence still needs to be repaired twice a day but the sea lions are starting to stay away from the entrance to the generator room with regular clearing which will also start happening around the burial cairns between the student house and the helicopter pad. The sea lions have started shifting the stones around a lot and we want to preserve this important historic area.

Marine Science and possible blind sea lion

Weather

  • Visibility: 15 Miles
  • Wind: 5-15 SE
  • Sky: Partly Cloudy
  • Water: Flat

Boats/Visitors

  • A couple visitors on island observing the elephant seal molt also Laura’s marine science class are doing transect studies in the intertidal zone, yesterday and today

Maintenance

  • Solar has been great lately so I haven’t had to run the generator too much and I have been able to run the desalinator periodically on solar power, still waiting for the new desalinator and once that is up running I would love to pressure wash all of the buildings, they have quite a build up of algae on them.

Ecological

  • A young stellar sea lion was acting strangely on the jetty yesterday, it wasn’t opening its eyes and it was the last one off the jetty, instead of diving off it carefully backed off the jetty tail first, it didn’t appear frail or injured but it was acting very strange which led me to think it was blind, it is branded so I am going to look for it to see if I can get a clear picture of the brand and maybe identify this sea lion and get it help if it needs it.
  • three goose nests were not able to be addled this year, so we will have some goslings running around, but the rest of the nests have been successfully addled
  • still 13 elephant seals, a few young males and mostly older females plus the male pup is still here, he seems to be doing pretty well although he does go swimming I’m not sure if he has started hunting yet

Census, new stellers and update on injured mammals

Boats/Visitors/Sightings

  • Lots of ecotour boats between 12 and 1 pm, and a few private boats as well, making race passage quite crowded

Mammal Notes

  • Some steller sea lions have arrived on the northwestern rocks! It’s hard to get an accurate count from this distance, but I estimate 12-15 including one really big one (a webcam viewer informed me that the big bull is branded “76Y”). Photographed below.
  • I got a closer look at the injured californian sea lion that was hanging out near the guest house earlier, and it definitely has an injury on its hind flipper. I saw it try to get into the water yesterday and it was pretty much dragging itself.
  • The injured female seal has nestled itself by the boat shed. I don’t see any further injuries on it.

    • Male = 4
    • Female = 1
