Killer Whales Everywhere!

What a killer day!

I think the rainy days might be my favourite so far. This morning it poured with rain as I drank my coffee, the mist hung low around the reserve and I could see the steamy breath of the sea lions as they yelled and yawned.

The ocean surface was glassy, and Ollie casually floated in the water around South Seal Rocks. Sometimes I think that otter has spent so little time around other otters and so much time around pinnipeds that he thinks he is a seal. The seals are completely unbothered by him, just giving him the occasional side eye.

I completed most of my to do list in the rain, which makes the cleaning tasks far easier. Around noon I headed inside to eat and just as I was about to sit down I noticed a few slow moving ecotourism boats in the distance. I ended up eating my lunch with one hand and holding the binoculars in the other to try and figure out what was coming my way. After a few minutes I saw at least 5-6 transients heading towards me so I ran out with my camera. As per usual they stuck to the outside of the reserve, although this time they passed by slightly closer. No hunting today, they were on the move with an adorable baby in tow. Each time it came up for a breath it basically flung it’s entire body out of the water. As I watched them I looked up and a flock of 19 brown pelicans flew over my head, I think the rainy days might be the best for spotting animals!

After that amazing experience, I went back inside to try and sit down yet again. I had barely taken off my shoes when I saw 2 more boats heading my way from the same direction as the previous ones. I pulled the binoculars back out only to find ANOTHER family of 5-6 transients following the same route as the others. These ones came closer and actually cut into the reserve, but not too close, sticking a couple hundred meters behind the South Islands. This family had an even smaller baby with them which was exciting to see. No hunting for these guys either, another quick pass by but I was grateful that it was the closest I’ve seen yet!

At this point I gave up on taking a break for the day. I continued on with my to do list and just as I went down to the jetty to take the salinity and temperature readings, 2 large killer whales popped up 100m in front of me. Of course I didn’t have my camera with me but I’ve never seen orca so close from land before, it was incredible. By the time I sprinted back inside to get my camera they were almost at the outskirts of the reserve. The current was strong so they came up that one time in front of me and by the time they surfaced again they were already out near Turbine Rock where they took another dive and I wasn’t able to spot them again.

Today was unbelievable, I am truly living the dream out here!

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!

  • Rolled fire hoses
  • Big clean of main house

Happy Friday!

We have been down to just 3 elephant seals the last few days! The two small females and one larger one are still enjoying the grass, however the largest female has not been around in a few days. The last I saw of her was 2 days ago when she was bobbing around in the water behind the student house, so I wonder if she’s just chosen to haul out on one of the surrounding rocks.

Ollie spent his day in the water near Middle Rocks, just floating and looking extra fluffy.

The Stellers were no where to be found today but the California sea lions have spent the week tucked in to the left of the jetty. They must be smarter than they let on because that area is definitely the most protected from the wind. They still require the occasional reminder to stay off the jetty throughout the day but otherwise behave themselves.

Lastly on the mammal side of things, the harbour seal numbers seem to have grown since I was here in March and with pupping season just a few weeks away I hope to see that number grow before I leave in June!

There are tons of pigeon guillemots around lately, I love to watch them on the rocks and I think my favourite thing about them is that their feet perfectly match the inside of their mouth. 

Hopefully this wind dies down in the next few days and I can get back to taking more photos!

Facility work:

  • Cleaned solar panels
  • Topped up battery electrolytes

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.

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, 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
  • Cleaned solar panels
  • Cleaned windows of both houses
  • Chopped firewood
  • Ran an equalization charge of the batteries
  • Mopped basement floor

Vessel Traffic:

  • 1 ecotourism vessel
  • 3 private vessels

Infractions:

  • 1 rental boat fishing within the reserve despite multiple communication attempts. Informed the local marina and reported to DFO

Weather:

    • Sky: Overcast, on/off rain
    • Wind: High of 4 knots, Low of 19 knots
    • Sea: Calm
    • Temperature: Low 9, High  11oC

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?

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.

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.

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

Oyster catcher: 22
Harlequin duck: 15
Gulls: 195
Cormorant: 73
Pigeon guillemot: 101
