So Many Sea Lions!

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!

A Busy Week: Entanglements, Fall Weather

Weather:

  • Sky overcast
  • Visibility 1-10 NM – intermittent fog with a consistent layer of wildfire smoke
  • Wind 5-15 knots W
  • Calm water, rippled surface

Visitors/Traffic: 

  • One contractor visited the island yesterday, along with Greg and Lawrence the day previous.
  • Minimal tourism and pleasure craft activity (5-10 boats coming through daily)
  • Today Marine Mammal Rescue and DFO visited the reserve by water to look for entangled sea lions that had been reported to DFO. Unfortunately we were not able to spot the animals reported. Despite multiple vessels, the view from the lighthouse, and even a drone!

Ecological Observations: 

  • The increase in sea lions seems to be slowing and tapering off. Wherever there is available space, they haul out and fight for the best place to rest.
  • The elephant seal ‘Erica’ GE103 is still sticking around, and spends most of her time resting near the base of the jetty.
  • We noticed a robin hopping around on the grass yesterday but unfortunately didn’t get a picture.
  • We did see one sea lion with an entanglement injury on Sunday evening. It was the same one reported to DFO by a visitor in the reserve (boating past). We were not able to spot him again, and today we found the flasher which had been hanging from his mouth on the ground.

Break in Foggy Weather: Census + Pelican!

Weather: 

  • Sky partly cloudy, some sun and blue sky
  • Visibility 10-12 NM
  • Wind 20-15 knots W
  • Sea state: fast moving currents, still fairly flat despite wind

The fog horn continued for 20+ hrs each day until today. For most of this week we have had less than 100m visibility, making it impossible to see even a boat passing through race passage or the end of the jetty. At some points, we could barely see the guest house from the main residence! It can be difficult to focus and/or work productively during these long periods of fog, as the fog horn sounds three long high-pitched “beeps” every 45 seconds. More info on the history of Race Rocks foghorns Here!

Visitors: 

  • There have not been any visitors to race rocks since Monday when Greg and a contractor stopped in briefly.
  • There have been 1-2 tour boats in the reserve daily, but we can often hear them before we see them in the fog. The sea lions are easily startled by them because of the limited visibility, and sometimes when the boats emerge from the fog the sea lions run into the water.

Ecological Observations: 

  • The sea lions have officially taken over the island! We have been dutifully repairing the electric fences daily to keep them from damaging the buildings and especially from disrupting the burial cairns.
  • There have been an incredible amount of interesting birds to observe this week, despite the weather. Today we saw a pelican while enjoying the sunshine right from our back porch! This is a new sighting for us at Race Rocks and we were quite ecstatic.
  • On the note of bird sightings, we are hopeful for the installation of a new bird tracking device on Race Rocks sometime soon which will allow us to view migratory birds passing through the reserve as it detects their tracking bands.
  • One of our favorite elephant seals, E103 or “Erica” has returned again. We were happy to see her looking healthy yesterday- she had been hiding behind the piles of sea lions, and we only saw her once we had shooed them to install more electric fencing.
  • Identifying gulls is incredibly difficult. Some of them look the same aside from a slight wing color difference or color of feet determining them as a separate species! We are wondering if the gulls we have been assuming to be non-breeding california gulls are actually thayer’s gulls. Back to the id books!

Census:

  • 96 Stellar sea lions
  • 383 California sea lions
  • 88 Harbour seals
  • 1 Elephant seal
  • 1 Sea otter

  • 113 California gulls
  • 20 Heerman’s gulls

Successful Sea Lion Rescue!

Weather:

  • Sky Clear and blue
  • Visibility 15+ NM
  • Wind 20-25 knots NE
  • Sea state: swells up to one meter
  • Temperature outside: 19.8 C
  • Pressure: 1021 hPa (decreasing)
  • We have been seeing consistent fog in the late evening, lasting for an average of 2 hrs. The fog banks seem to move over us from Port Angeles.

Visitors: 

  • Marine Mammal Rescue and DFO visited yesterday (more on this below).
  • Steady flow of pleasure crafts and whale watching vessels over the long weekend.

Sea Lion Disentanglement: 

  • Yesterday Marine Mammal Rescue along with the support of DFO vessels and staff came to help a sea lion with a plastic packing band stuck around his neck. They were able to successfully dart the sea lion with a tranquilizer injection, remove the band, give him tracking tags on his front flippers, and take a blood sample. When this was done they injected a reversal drug to wake him up and with a little scratch he was back on his way!

Ecological Notes:

  • The seagull chicks have officially flown the coop! Only a few remain and we are able to move around the island again without bothering the nesting birds.
  • This year we have noticed significantly less trash left behind by seagulls than last year. Our best guess is that they had more food available to them this summer, which would also align with observing them regurgitating much more fish that the previous season.
  • The sea lions have been increasing in numbers every day. The new fencing material that Nick and Greg used seems to be working much better than the wire that we tried last year, preventing them from damaging the island infrastructure. We have been letting them rest on the jetty this week but we will soon need to install more fencing in preparation for student visits.
  • Yesterday we found two turnstones which appeared to have been killed by the gulls while we were investigating the area near the codar antenna (SW Great Race Rock).
