I heard back about more information on the recently arrived female juvenile elephant seal pup, with green tags E103 and E135. Dr Patrick Robinson, the Director of the Año Nuevo Reserve and Lecturer at University of California Santa Cruz, sent a report of the history of the seal’s sightings and said, “It’s always great to get these updates… we greatly appreciate it!” The seal was born in the 2018 winter season, which makes her just over two years old. She was seen a lot during the winter and spring of 2018 at Año Nuevo Reserve. Researchers took two blubber samples to study bioaccumulation. The seal wasn’t seen again until the fall of 2019, when she spent a month at Race Rocks between September 7 and October 11. Fast forward a few months, the seal came back to Race Rocks two days ago, on March 23. She appears to be in the early stages of her catastrophic moult of her fur and skin, judging by the patches on her sides.

The youngest elephant seal pup returned yesterday morning from her one day adventure in the sea. She spent the whole day sleeping by the wood pile. The oldest pup has been gone for the past two days. A new adult female elephant seal arrived yesterday. She is most likely one of the four mothers that was here in January and February. So far the three have come back a month and a half after they each weaned their pups, which happened on January 21, February 4 and February 9.

At today’s 16:31 high tide, after recording the salinity and temperature of the water, I hooked up the hoses and pump to top up the seawater in the cistern. The gas powered water pump sucks water through a hose with a strainer dropped off the end of the jetty. The water is pumped through 76 m (250′) of fire hose up to the cistern. Over a couple hours, tens of thousands of litres of water were pumped into the underground cistern, which should feed the desalinator for the next month and a bit.

Yesterday, there was one pleasure boat that zoomed through Middle Channel and stopped by the rocks to take photos of sea lions. This afternoon, the Canadian Coast Guard lifeboat Cape Calvert, appeared to be out for a cruise around Race Rocks from the base in Victoria. They came in for a closer look and a couple of the crew appeared to be snapping photos of Race Rocks with their phones. This is a very photogenic place. This afternoon, Guy, Corey and Christine from Pearson College delivered a new fridge and took away the old one that recently stopped working. They also brought some fresh food from the Pearson kitchen, which is closing down for a while.

Here are a few photos from the past two days:

Elephant Seal Excitement

Posted on by

Wind: yesterday 0-36 knots from W, E, S, W throughout the day, today 9-40 knots from W
Sea State: yesterday rippled changing in late afternoon onwards to chop up to 1 m, today calm in early morning then up to 1 m chop for rest of the day
Visibility: both days 10-15 NM
Sky: both days overcast
Temperature: yesterday 5-9 °C, today 7-10 °C
Atmospheric CO2: 413.72 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The ecological highlights of the past two days were a bald eagle eating a bird and as usual the very entertaining elephant seals.

A new female elephant seal arrived on the main island this morning. She is tagged T563 on tags on each of her tail flippers. I contacted elephant seal researchers to check her history. She was tagged as a pup in the birthing season of 2010-2011, on the Farallon Islands, off the coast of San Francisco. That makes her just over nine years old. She hasn’t been seen by those researchers since. Last year, Ecoguardian Laas spotted her for the first time at Race Rocks on March 21. This morning, the alpha male was attempting to mate with her. Now she is hunkered down by the flagpole, shielded from the strong west wind. The adult males were bellowing at each other for most of the day. The beta male has an advantage of a high lookout point, on the helicopter pad. He has been up there since January without leaving. I am not sure he knows how to get down, as I have seen him attempt a few times before turning around. He must be getting hungry.

The oldest of the two female pups might have gone for a swim yesterday. I saw her with wet fur climbing up the rocks from the east bay.

The youngest female pup and oldest and only male pup have been hanging together, vocalizing with each other and appearing to play fight.

In between watching nature neatos, I did some maintenance around the island. I used a new two metre pressure washer wand to get the algae off the north side of the boat house, tank shed and Race Rocks sign. I hope to clean off the rest of the buildings over the next few weeks, now that the desalinator is pumping lots of freshwater. I also fixed the door on the freshwater shed with a new hasp and a piece of wood to stop the door from blowing inwards.

No boats or visitors were in the ecological reserve over the past two days.

Here are some photos from the past two days:

Clear Skies and Many Birds

Posted on by

Weather: 

  • Sky clear and sunny- no fog!
  • Wind: 10-20 knots SW
  • Water: Rippled. Strong currents today (+4.4 knots)
  • Visibility: 10 miles

Visitors/Boats:

  • Greg came by today with some water that we pumped into the main tank. We are told that the new desalinator should be on its way soon, but is going to take a few weeks to ship.
  • A few whale watching boats today (10-15). Many came close (-50m) to the elephant seals in the jetty and the sea lions on middle rock. We often see them within 10m of the sea otter and kelp patch that it calls home.

Maintenance: 

  • A few days ago we replaced the worn Canadian flag on the flagpole. Today we noticed that the entire rope/pulley system had somehow blown loose and fallen to the ground. The pole is to high for us to reach the top with our ladder, so when it is less windy we will have to take the pole down to make repairs (this will be difficult with so many seagulls about).

Ecological: 

  • Many interesting birds in the reserve this week. Today we spotted some western sandpipers, a couple short billed dowitchers, and a ruddy turnstone all from our kitchen window!
  • Every day we see more and more sea lions. Greg said that he even spotted a stellar sea lion on his way today.

They Grow Up So Fast!

Posted on by

Weather: 

  • Wind: 20-25 knots westerly
  • Sky: Some early morning fog, partially cloudy
  • Visibility: 15 miles
  • Water: Rippled

Boats/Visitors: 

We haven’t had any visitors to the island over the past few days, but the whale watching traffic continues to be steady throughout the day. The concentration of traffic typically lies between 12pm and 8pm.

Ecological: 

  • The seagull eggs are hatching at full force! There are now too  many chicks to keep track. They like to nestle in the taller grasses or nearby rocks to keep out of the wind.
  • The large elephant seals are still moulting, and continue to scoot between the centre of the island and the jetty to cool off and relieve their cracking skin.
  • The oyster catcher chicks are doing well but they are much more elusive than the other birds.

 

Big Creatures and Big Winds

Posted on by

Weather: 

  • Visibility 14 miles
  • Partly cloudy, sunny
  • Wind 25-35 knots (gale warning in effect)
  • White caps and spray. Waves up to 4 m.

Visitors/Boats: 

  • The college boats are still in for maintenance, so we have not had any visitors. We are hoping to go to the main island soon but winds were much too strong and unpredictable today.
  • The past couple of days we have seen a handful of eco-tourism vessels and pleasure craft. Some vessels have approached within 20 m of our jetty and surrounding Great Race Rock. The elephant seals have been scooting up the jetty to get away and the few sea lions remaining appear disturbed.

Ecological: 

  • We were sad to find the missing gosling deceased. It seems that due to its injured foot it was easy prey for the bald eagles that have been swooping by lately.
  • We are now in the company of 4 very large male elephant seals who have stopped here to moult. They are enjoying taking regular baths in the shallow and protected jetty waters.
  • The occasional sea lion has stopped by and hauled out for a rest, but otherwise they have all moved on.
  • The seagulls are becoming more and more aggressive. We are anticipating the need to wear protective equipment sometime in the coming week!

Maintenance/Other:

  • We are still waiting for the delayed desalinator, so we are conserving water as much as we can in the meantime, as it is not possible for more to be delivered without the use of the college vessels.
  • We have been collecting shingles as the high winds are tearing them off of the sheds (new metal roofing is expected sometime soon), and often find fishing lures, bits of rope, and other litter wedged into the rocky intertidal.
  • The beautiful sunny days lately have meant that we have been able to operate entirely on solar power most days. We’ve been having some troubles with the battery charge readings but otherwise the system is working without a hitch!

A Quiet Week

Posted on by

Weather: 

  • 15 miles visibility
  • Skies clear with some clouds
  • 40+ kn wind
  • Rolling waves up to 1/2 m breaking into whitecaps

Boats/Visitors: 

The boats at Pearson are in for annual maintenance so we have not had any college visitors. The wind conditions have limited all boat traffic.

Ecological:

There are have been no sea lions over the past few days. The gosling that appeared to be injured has not been spotted in a while. The large male elephant seals are clearly moulting now and have been fighting over the best sleeping spots. The seagulls have become more aggressive and will now fly towards us even if we keep a distance from their eggs.

There has been DND blasting nearby almost every day lately. The birds take flight and the mammals are visibly disturbed.

Census: 

  • 30 harbour seals
  • 5 elephant seals, all moulting. 4 male 1 female
  • Roughly 200 seagulls
  • Two families of geese, minus one missing gosling
  • Two barn swallows nesting in our rafters

Whales! (and census)

Cackling goose and Snow goose

Posted on by

Light Wind in the morning, String Westerly in the evening. Cloudy with scattered showers. Rain in the evening. Tour boats:8 1030 flyover by a small float plane The Cackling Goose and Snow Goose (note — a new record for Race Rocks ) are still foraging on the grass on Great Race. The Canada Geese often chase these two smaller geese. The Sea lions all moved to the East side of West Rocks this morning. Up until today, they had been on South Rocks since I got here in the middle of March. Eagles are regularly flying over Great Race and making all the Gulls take flight, but I have yet to see an Eagle grab a Gull.
