California sea lion with transmitter/flipper tag

Posted on by

Wildlife: California sea lion with transmitter and flipper tag at jetty.

Weather: Clear in the morning, fog occasional visitor in the afternoon.

Facility work: Checked various fluid levels, routine maintenance on Honda backup generator, diesel generator topped up, storage batteries topped up with distilled water, fence inspected and repaired, solar panels cleaned, sea temperature and salinity taken.

Visitors: Biology class from LBPC for overnight stay.

Vessels: Nine tour boats noted. Our closest neighbors are the variety of ships that pass to the south on their way to other parts of the world. Some carry thousands of people, others carry cargo that could cause huge change to this fragile ecosystem… life on the edge.

GPS Tagged California Sea Lion

I make maps for a living, so you better believe I was excited to find a sea lion with two telemetry tags pinned in its flipper-pits. I reached out to Kendra and our contacts at Oregon State and got an answer the next day!

California sea lion: branded X103

X103 is an animal they tagged (ODFW, WDFW, UCLA, and others) in Astoria, Oregon on August 29, 2024, as part of a research project looking at disease ecology and movements of California sea lions.  More information about the project can be found here: at this link  (X103 isn’t listed here yet but the 2023 cohort is)

For information on the whole research project: The Eastern Pacific Marine One Health Coalition https://marineonehealth.or

Maintenance:

Since talking with the Oregan taggers, I’ve been reaching out to our other animal reporting partners and getting updated emails and protocols. I’ll use this information to update in the SOP.

Tagged Sea Lions

Scott spent some more time with the chainsaw today. He is putting a huge dent in the pile of logs down by the jetty, and the stacks of firewood in the basement are steadily growing for the winter.

As the numbers of sea lions on the island continues to climb we have been seeing quite a few tagged and branded individuals. These markings are implemented by researchers in Oregon and along the West coast of the US. They give the researchers an idea of animal movement, functional population size, and more. If you ever see a tagged or branded sea lion remember to report it!

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.

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

So Many Sea Lions!

Posted on by

I swear the sea lions have doubled in number since yesterday’s census! Or maybe they just ALL decided to hangout around the jetty today. Between the Stellers and the California’s I counted 40 sea lions out front this afternoon! Okay, so maybe they haven’t quite doubled…but there is about 10 more today and that seems significant.

One of the California sea lions had an orange flipper tag with the numbers 14-1 on it. While the Vancouver  Aquarium Marine Mammal Rescue Society uses these tags, this is not the numbering system they use so I’m still on the hunt to find out where he came from. I’ve reached out to a few of my contacts in Washington and California to see if its an American tag but no luck so far. I’ll be sure to update the blog when I find out!

I also noticed a different California sea lion with a large wounded front flipper. The wound was clean and pink with no noted necrosis or signs of infection and he seemed otherwise fat and healthy. All good signs, especially when there is a wound of that size! Fisheries and Oceans Canada (DFO) keeps track of all incidents, disturbances, deaths, injuries, etc when it comes to marine mammals so although this animal doesn’t require intervention I did report it to them so they can add it to their yearly totals. I hope this guy sticks around over the next few weeks so I can observe his healing progress!

Aside from staring at sea lions, I did do some actual work today. While I love how lush and green the site is right now, the plants have overgrown so much that they’ve made some of the paths nearly non existent. I decided to fix that today with a weed whacker which I had way too much fun with. I got a few done and  I still have a few paths to work through, trying my best to only clear the edges and not take away anything that isn’t necessary. We’ve just had so many guests and students this month that I want to ensure everyone actually has a nice path to walk on!

I also found a few new patches of these pretty pink flowers around the house today. It amazes me how many different flowers and plants grow here and I wonder how they got here. Some of them pop up in the most random places so I wonder if they were intentionally planted at one point and have now spread. I enjoy it either way!

Facility Work:

  • Rolled fire hoses
  • Big clean of main house
  • Weed whacked along the paths
  • Cleared out garbage from student house basement
