Wildlife notes:

The California sea lion with the wounds on his flipper hasn’t been spotted for a few days.  The new black oyster catcher chick hatched on July 5 in the open on the western shore has been moved up higher on the rocks.  The pigeon guillemots are easy company – neither the gulls or the oyster catchers mind them around.

Another little climber. Hatched July 5.

Notes for Day 2 at Race Rocks

Census day

After the morning cleaning of the panels I decided to wander beyond the electric fence.  Surely it wasn’t meant to keep me in and how else could I complete the census.  It was liberating wandering about and I even peered into a spectacular tide pool. I am used to different methods walking in certain terrain: through the sprawling yellow cedar or “shin tangle” of coastal BC bogs or the Tuckamore of Newfoundland, you bob and weave, through Devil’s club it is more like Thai Chi. Today I learned how best to walk with the birds.  I started with the head down, quick and deliberate, travelling from one small gull free patch to another. The better approach is to travel very slowly, only a few steps at a time then have a long and still pause. I observed many nests during my slow walkabout and was surprised by number of the poorly formed or empty ones. There are often bursts of commotion when all the gulls take flight but I haven’t yet seen an eagle at that time or any other obvious cause for the scare. Even though I feel more comfortable walking past or through hovering gulls, I still wear my helmet and often carry a broom over my shoulder.

My day ended watching the cormorants leave in the fading light.

A Very Soggy Sunday

Posted on by

Today was a very soggy, rainy day. The birds all appeared drenched and disheveled, the elephant seals spent the day in the water, and Ollie was nowhere to be found.

One lone humpback passed by just on the outskirts of the reserve, sending a big spray into the air each time it surfaced. The ocean was calm all day which is the very best for spotting whales. On a much smaller scale I ended up with some small jellyfish in my water bucket when I was taking today’s salinity/temperature sample. There must have been hundreds in the water around the jetty!

The sun finally peaked out around 6pm, just in time for me to watch a gull harass a juvenile bald eagle. It blows my mind how savage and fearless these gulls can be.

Vessels:

  • Ecotourism: 8 vessels

Weather:

  • Sky: Cloudy/Rainy
  • Wind: Low of 1 knot, High of 11 knots
  • Sea: Calm
  • Temperature: Low 11•C, High 13•C

Sea: rippled in morning, up to 2′ chop in afternoon
Air temperature: 11-15 C

DND Blasting:
There was one DND blast at 14:05 on July 12 at nearby Rocky Point.

Visitors:
Greg and Bruce visited this afternoon to deliver 1,400 L of freshwater and a new first aid kit.

Maintenance:
I did the routine tasks of cleaning the solar panels and house windows, topping up the water in the 24 deep cycle batteries, fixing the electric fence, tidying, and maintaining the freshwater system.

Ecological notes:
There have been a lot of humpback whale activity over the past few days to the west, south, and east of Race Rocks. The whale watching boats have been active in the area. From what I hear on the VHF radio, they have been very pleased with the humpback viewing. I have not seen any whales swim through the ecological reserve.

I heard back about the tagged elephant seal, from the researcher at Año Nuevo Natural Reserve, in California. The juvenile seal, tagged H999 and K646, is a male who was born in January 2022. He was previously observed here and reported to the researchers on April 1, 2023. He has been moulting here for at least the past several weeks. He appears to be almost complete the moulting process, so he might be moving on soon to feed in the deep waters.

Weekly Census observed on July 13:
elephant seal: 1 juvenile (tagged H999, K646)
Steller sea lion: 3
harbour seal: 79
bald eagle: 2 adults, 1 juvenile
raven: 1
cormorant: 7
black oystercatcher: 6 adults, 1 chick (that I could spot today)
pigeon guillemot: 148
glaucous-winged gull: 387 adults, 120 chicks
surfbird: 12
killdeer: 4
western sandpiper: 3
barn swallow: 3

Groundhog Day

Posted on by

Wind: yesterday 0-52 knots from S to W, today 0-18 knots from W to NE
Sea State: yesterday rippled with waves up to 1 m in afternoon and evening, today rippled
Visibility: yesterday 5-10 NM, today 15 NM
Sky: yesterday rain then patches of sun, today clear
Temperature: yesterday 5-12 °C, today 3-5 °C
Atmospheric CO2: 414.49 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

This morning at sunrise, the elephant seals saw their shadows. As the lore goes for their fellow mammal the groundhog, that means six more weeks of winter. Hard to believe with the crocuses blooming and daffodils buds almost ready to burst. Although, there is snow in the forecast for tonight and tomorrow as the temperature drops to 0 °C.

There were no visitors to the island. Two eco tour boats were seen in the reserve this afternoon.

Here are the results for the weekly census, conducted in the afternoon of Sunday, February 2:
10 elephant seals (3 female adults, 4 male adults, 1 female pup, 1 male pup and 1 unknown gendered pup)
147 steller sea lions
288 california sea lions
104 harbour seals
10 bald eagles (5 adults, 5 juveniles)
1 raven
109 brandt’s cormorants
182 pelagic cormorants
49 double-crested cormorants
24 canada geese
931 gulls (most are thayer’s gulls)
18 black oystercatchers
1 whimbrel
1 surf scoter
8 harlequin ducks
16 black turnstones
1 snow bunting
1 fox sparrow

A Foggy Day

Posted on by

Weather:

  • Wind: 5-15 knots NE
  • Sky: Foggy, some showers
  • Water: Rippled
  • Visibility: Up to one mile

Visitors/Boats:

  • We haven’t seen very many boats today as it has been very foggy. We spotted three whale watching vessels, and one unmarked zodiac.
  • Yesterday was a busy day for whale watching, with boats heading in many directions through the main passage. There has been a young elephant seal resting on the jetty for the past two days, and it appears very agitated when the boats come close (within 25 m).

Ecological: 

  • We have noticed that there are a handful of sandpipers on the island this week
  • There is a small elephant seal with a few minor flesh wounds on its abdomen resting on the jetty. It appears to be part way through the moulting process.
  • We spotted two deceased oyster catcher chicks on the paths this week. They were very small, so its possible that they were unhatched. They didn’t appear to be injured. The other chicks are thriving and growing incredibly quickly.
  • Another male stellar sea lion hauled out onto middle rock a couple of days ago.

Maintenance:

  • On Monday a plumber came to fix a leaky faucet part in the main residence.

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.

 

Census, more stellers and fog continues

Posted on by

Weather

  • Visibility: 10 miles
  • Wind: 20-25 knts W
  • Sky: Clear
  • Water: Ripply
  • Heavy fog in the morning and evening

Mammal Notes

  • More and more stellers have started arriving on the surrounding rocks. I saw stellers on the southeastern rocks for the first time today.
  • No sign of the malnourished/injured california sea lion for the last 2 days, which leads me to believe that he may have finally passed away
  • Spotted both the seal pups today, and looks like they’re getting pretty big. They’re about half the size of the adults now.

Bird Notes

  • Geese continue to remain on the island after their return from their long absence. Counted 6 today.
