Monday Update

Posted on by

Another day of blue sky and sun but unfortunately another day of wind too! 30 knots today and it looks like it will continue through the rest of the week.

Due to the weather I did not see any boats on the water today aside from cruise ships and freighters on the horizon.

I was able to clean all the house windows on the outside before the wind nearly took the brush out of my hand and I had to move onto indoor cleaning and organizing.

When moving the sea lions from the jetty this morning I did notice that one of the California sea lions has what appears to be an old eye injury. His other eye is normal, his body condition is great, and it is overall not concerning.  Just thought it was worth mentioning because it caught my eye – no pun intended.

Not the most eventful day today, but great nonetheless!

Sea Otter Facts and Facility Work

Posted on by

Today was a cloudy and drizzly day but I managed to get a good chunk of work done, all while hanging out with Ollie the sea otter. I think that’s one of the things that makes this place so special is that you can be scrubbing bird poop off solar panels in the rain and look down and see this fuzzy little otter staring up at you. I’ve spent a lot of time working on and around the ocean and never have I experienced wildlife like this.

Since Ollie has been around so much lately I figured I’d make this post a sea otter specific one (since you might find that more interesting than hearing about the fire hoses I rolled).

Sea otters are a keystone species, meaning that other species within the ecosystem largely depend on them and without sea otters there would be drastic changes to those ecosystems. Sea otters predate on sea urchins who graze one kelp. The sea otter’s urchin heavy diet keeps the kelp forests from being decimated by urchins, and as a result kelp forests flourish in the presence of sea otters.

Ollie wrapped up in the kelp he helps protect

Urchin’s aren’t the only thing sea otters eat, you’ll also find them munching on clams, crabs, mussels, and other marine invertebrates. Adult sea otters need to eat a quarter of their weight in food a day. To put that into perspective – if you weigh 150 pounds, you’d have to eat almost 40 pounds of food PER DAY!

Picking out his next snack

Sea otters do not have blubber like other marine mammals do, instead they have the densest fur of any mammal, with up to one million hairs per square inch! If they aren’t busy eating, then they are busy grooming. That much fur takes a lot of upkeep and is their only source of insulation. The constant grooming traps air and heat next to the skin, preventing the skin from getting wet and keeping them warm in the process.

Ollie grooming his hind flippers

Ollie, Race Rock’s resident sea otter, is one of few sea otters seen this far south in BC. He is easily recognized by his light blonde head and by the pink scar on his nose. He’s adored by many, and any day I encounter him I consider to be a great day!

Now onto the less adorable items…

Facility Work:

  • Filled cistern, fresh water flushed the pump, rolled and stored fire hoses

Friday Update

Posted on by

The Steller sea lions have taken over the rocks to the right of the jetty which has resulted in the California sea lions inconveniently taking over the jetty and spilling over into the rocks on the left. Usually a calm and careful walk down the jetty clears them off but by the time I get back to the shed they are already back. Some seem to learn quicker than others or are more fearful of humans so those ones find themselves a new spot right away. However there are always a few stragglers that don’t seem to care in the slightest which results in me taking many trips down to the end of the jetty and back.

When I’m here I try to do everything in my power to not disrupt the animals, however it’s important to keep the jetty clear for when our boat arrives as well as for emergencies. It can also be dangerous at a very low tide if there are sea lions on the jetty and something spooks them. It’s a long drop into very shallow or no water and when something sets them off they seem to react first, think later. So really, a clear jetty is for both human and animal safety. Thankfully there are plenty of other areas for them to snooze and sunbathe and eventually they get tired of seeing me on the jetty and find themselves a safer place to relax.

Ollie spent his day in the kelp beds behind the student house again, grooming and sleeping before moving onto the rocks to settle onto a not so comfy looking bed of mussels.

The same 4 female elephant seals are still here. Elephant seals go through something called a catastrophic moult each year where they shed their fur as well as their top layer of skin. It’s quite common to see these guys looking pretty rough but all 4 of the ones that are currently here appear to be in good condition.

Facility Work:

  • Topped up battery electrolytes
  • Started filling the cistern, it is very low so I plan to run the pump tomorrow too

Vessel Traffic:
– 1 ecotourism vessel
– 2 cruise ships on the horizon and multiple freighters/tankers

Visitors:
– Cedric to help me fill the cistern and with a few other tasks around the site

Weather:
Sky: Sun and clouds
Wind: High of 10 knots, Low of 6 knots
Sea: Calm
Temperature: Low 7, High  13oC

Branded sealion, desalinating water with sunshine, Good bye Race Rocks

They all came to wave goodbye

Eco-guardian cross over day. I arrived here barely over a bout of sciatica. I wasn’t sure if I should cancel my week but thought I could do all the absolutely necessary tasks, even if I had to crawl to take the water samples! As it turned out I was able to clean the solar panels, top up the batteries, collect enough wood to keep the house warm, clean the house, start a thorough cleaning of the fuel shed, scrub the walkways in the rain and do the necessary tasks. It was difficult though not to carry out the tasks I enjoy, like carrying a bucket of water to clean the lamp room or splitting wood.

I love the challenge at Race Rocks of living with a small environmental foot print. The abundant life here, that I deeply care about, inspires me to decrease my fuel consumption. This visit I did not need  to use the house furnace and heated my hot water on the woodstove. I even used this method of heating water for “Thai” showers. Cleaning the solar panels when they have dew on them and the walkways in the rain helps too. If I didn’t love my coffee first thing in the morning I could probably cook on the woodstove too. Maybe next time!

Observations

The 2 moulting elephant seals are still by the jetty. One is looking very good, all open sores are healed over. The other one is still panting away and shivering. I sent a video and have heard back from Candice at marine mammal rescue at the Vancouver Aquarium  and she would like to be kept informed if his status changes (rescue@vanaqua.org). Still no luck getting his tag #. I should note that I have not seen any infant seals this visit. I have scanned the rocks. My usual visit is in late April and there are often nursing pups.

The branded sealion 1191 below has been reported and we await back information.

Finally the two immature bald eagles are on the island at the same time and I believe they are the same age, less than a year. Do you agree?

Visitors

Greg is bringing out several classes for low tonight today

Vessels

Several tour boats have gone by already today (13:00 hours)

Facility work

Cleaned the solar panels

cleaned the house so it is ready for Ilka and Alan Olsen the next eco-guardians

wood to house

I am currently running the desalinator on sunshine! Amazing.

This is the screen we live by on Race Rocks. It tells how how much energy we are using and how much we are producing. Right now the sun is producing 4.88 kw and we are consuming 3.8 kilowatts while running the desalinator.

Weather

The day started out with thick cloud cover. The sun broke through around 1400 hrs. The wind is currently 13 knot SE. Scattered clouds.

Mating has begun

Posted on by

Observations: I am combining Saturday and Sunday. I wasn’t able to log in until Monday morning. Usually I like to write daily while events are still fresh that wasn’t an option.

The Mist Maiden, Romanzoffia tracyi, a red listed plant, is not yet blooming but coming up on the island.

There are 2 elephant seals on the island. They are both female. I am enclosing revealing pictures because often in posts the gender of the elephant seal can be assumed. In the future these pictures will be evidence!

The past 3 mornings I have opened the basement door to a new goose egg on the pavement being eaten by a gull. Why do they choose to bring the eggs to our door? Is it the least likely place to have it challenged?

…and the title for today, mating has begun.

 

Maintenence

Both Saturday and Sunday the solar panels were cleaned

The batteries topped up on Saturday

The fridge cleaned out

wood brought up to house for burning

Visitors and tour boats

On Saturday there were about 10 ocean touring boats. On Sunday closer to 30. As well on Saturday there were outrigger kayaks navigating Great Race.

The Weekly Animal Census

Posted on by

Today, it was time for the weekly animal census on Race Rocks – a longstanding tradition (see the full archive, here) that allows us to keep track of an ever-fluctuating population of birds and marine mammals. The morning weather wasn’t particularly promising, with wind, rain, and dark overcast skies.

Combined with high tides and a rough sea state, perhaps it wasn’t entirely surprising that the numbers seemed a bit lower than usual – with the harbour seals in particular mostly hiding out in the waves surrounding the South Rocks, and thus rather tricky to count. Alas – who was about?

Census equipment – species list, binoculars, and a clicker to keep track of everyone

 

March 27th Animal Census

Birds:

Oyster catcher: 22
Harlequin duck: 15
Gulls: 195
Cormorant: 73
Pigeon guillemot: 101
Juvenile eagle: 1
Adult eagle: 1
Canadian geese: 9
Shore / Surf birds: 15
Turnstones: 10

Marine Mammals:

Steller sea lions: 14
Harbour seal: 21
Male Elephant seal: 1 (back on land after a lengthy morning expedition)
Female elephant seal : 0
California sea lion: 24

The weather did eventually start to calm down a bit – still hopeful to catch my first RR sunset of the trip later tonight!

 

Facility Work:

  • Weekly Animal Census
  • Continued algae clean-up on Generator Roof
  • Chopped Firewood
  • Prepared new Water Filters for both the Keeper’s Residence and the Marine Science Building
  • Early AM generator run to top up batteries, PM solar enough to reach charge status of 100%

A Steller Monday

Posted on by

What started out as a very foggy morning turned into a blue sky and sunshine kind of day with an unbelievable sunset!

 

 

 

 

 

 

 

 

 

 

 

Today’s Animal Notes:

 

 

A large male Steller sea lion has been hauled out on the rocks near the jetty all day and he make the makes the California sea lions look tiny in comparison! 

 

 

 

 

 

 

 

 

A female elephant seal spent the morning sunbathing in the water behind the student house. I think this may be the same one that’s been hauling out on the South Island. She’s yet to come ashore here though. 

 

 

 

 

 

 

 

I spotted 3 harbour porpoises just outside the reserve this morning, I see so many back home in Vancouver so I’m surprised that this was the first time I’ve seen them here.

 

 

 

 

 

 

 

 

I came across a giant pacific octopus at low tide (deceased unfortunately) but it made a great meal for a young gull and an even better learning opportunity for the students that are currently on the island!

 

 

 

 

Finished the night off by watching the sunset with the blonder of the two new otters as it floated off the rocks behind the student house. (No photos, just enjoyed the moment).

Facility Work:

  • Filled the cistern 

Noted Vessel Traffic:

  • One ecotourism vessel
  • Two private vessels

Weather Events:

  • Monday, March 18:
    • Sky: Foggy morning, clear blue sky until sunset
    • Wind: High of ESE 11 knots, Low of SE 1 knot
    • Sea: Glassy all day long
    • Temperature: Low 7oC, High  13oC

Early Spring = Cleaning

Posted on by

Ecological Notes:

  • The birds are starting to pair off …. Geese, Gulls, and Oyster Catchers most notably. Lots of Adult Bald Eagle courtship in the air.

  • Young adult Elephant Seal male arrived a few days ago. After resting a couple days, he has spent most of every night bellowing and calling from a high point on the island.

One of his favourite calling spots is right below the window!

Realizing the female is calling from the other side of the rise

  • One adult Female Elephant Seal has since come to the island. She moves towards the males calls, but retreats when he tries to approach her. I can only speculate that she instinctively wants to haul out for her moult with other seals, but feels he not big enough to breed with(?)

She calls out a lot as well

  • I’m hoping his calls may attract others to the island
  • Normally I just get reports of “Ollie” the Sea Otter, but while I was up by the north camera, I could see him just beyond  helicopter rock.

very far away

  • 4 Transient (Biggs) Orca travel through the northern edge of the reserve without cutting in to hunt. I watched from the north camera rock, to see if they might double back, but they continued east.

T019B “Galliano” … 28 year old male

Visitors:

  • 2 techs from the Coastguard returned to complete repairs to the fog horn.
  • The upcoming Eco-Guardian also visited for an overview of the Ecological Reserve and day to day operations.

Facility Work:

  • Added water to the cistern to allow more desalination to fill the main water tank.
  • Gathered all the  hose on the island to pressure wash the pier.
  • Tackled the rather daunting job of moving and bucking the very large logs collected when I had help to pull them out of the ocean.  Even with a good understanding of leverage and pivot points, these logs were a brute! Most were well over 12-16 inches in diameter, and the bucked sections were 400-500 lbs! Task was cut short by rain (and exhaustion!), but moved the next sections into place for  the first buck. Next will be moving them to the final bucking and splitting area up top.

DND events:

  • some blasting, some fires

Noted Vessel Traffic:

  • Still occasional Eco-Tourism vessels

Foghorn and tower updates

Posted on by

Ecological Notes:

  • Large female Elephant Seal came up to the centre haul out area on the Island. She appeared to be one of the females from last year. She spent regular periods ca.ling out, before leaving after 3 days ……. a pattern I have seen each time any single Elephant Seal has come to the reserve this season

  • Juvenile Golden Eagle still visiting occasionally
  • One morning there was an extra high number of eagles here….. 40+. I looked for new carrion or any other reason for there to be so many, but couldn’t find any.
  • California Sea Lion that had a band removed a while ago is around, and his neck appears to be healing well

Visitors:

  • 2 techs from the college
  • 3 techs from coastguard

Facility Work:

  • Pearson College IT installed new Starlink system at the top of the tower. Still awaiting implementation

  • Coastguard attempted to repair foghorn system but are awaiting parts now, and serviced the battery system for thew lighthouse
  • Cleaned the filter on the main house furnace, but detected a probably leak in the main fuel line
  • Received new files to re-work the chainsaw chain
  • Cleaned the rest of the outside walls of the student building, save for one area where I couldn’t position  the ladder safely by myself.(once the green is gone, the residue comes off after a couple rains)
  • Cleaned a small section of the roof, but found it pretty sketchy for a “larger” old guy to extend his reach that far above the ladder!

  • Daily attempts to keep the boat ramp clear of driftwood

Noted Vessel Traffic:

  • Eco-Tourism vessels
