Back on the Rock: March 2– 4th

Wednesday morning, while tide, wave height and current speed were just right; we slipped a crew change through a narrow window between two gales. As we waved goodbye, and I turned to get moved in, the barometer started to drop again.

After four and half months away, it was good to be back on Great Race with its familiar views of the Strait of Juan de Fuca. As an averred naturalist, I couldn’t help notice that North Rock was bristling like a military brush cut, with 350 – 400 cormorants. All three species Pelagic, Double-crested and Brandt’s, were ‘drying out’ on this strategic roost after foraging in the sea. An adult Bald Eagle swooped in and the cormorants en masse, hit the water. The tidal ebb started to clear them out to sea, pulled by moon and pushed hard by rainwater rising in the Salish Sea. The cormorants dispersed and the counting moment was over; some flew, some dove and others disappeared into the gloom, as more rain squalls swept in.

Concentrating on moving in and checking all systems in order, counts were put on hold for Thursday’s census. Chunk, the big, pup-killing, male Elephant Seal was lying where he had apparently been, on and off, for a week. He was a little too close to the path for comfort, which meant that coming and going to the energy building involved tip-toeing by, while keeping a look-out for his eyes to open and being ready to run, if necessary. Of course it is never necessary but absence makes the fear forget.

Riley left things fairly ship shape and I knew that everything was going to be fine when the old Lister generator roared to life. In the evening, the wind gradually rose to 36 knots, ESE, a speed and direction that makes the back door of the house whistle a weird, three-toned tune, but it didn’t keep me from a deep sleep.

Seawater sampling came early and the morning weather was fairly wet and windy. The sun broke out with rainbows in the afternoon and the wind dropped to less than 10 knots. As the sun sets now, the forecast is calling for light winds, a chance of showers Friday morning with rain again by afternoon.

Once established that it was a beautiful afternoon, three small whale-watching boats came out to watch the sea lions on South Rocks. It always makes me a little nervous to see them with their human cargo in close to the south reefs and the sea lions. Their insurance companies probably wouldn’t be too keen on that sight either.

Today was census day and there were interesting differences in the timings of comings and goings of different species. Today, the Pigeon Guillemots were here at first light and numbers kept increasing until about noon. They were all gone by late afternoon. The Black Oystercatchers were together in a squawky flock early in the morning and then dispersed. The sea lions hauled out mostly in the morning but additional individuals hauled throughout the day. The cormorants started roosting late morning and were mostly back in the water by late afternoon. The Harbour Seals hauled out in the late afternoon. There were few gulls in the morning, but by mid-day some were pairing up and looking like they might already be standing near their nest sites. By late afternoon there were over 200 gulls roosting on the island but they were gone by the time I came back from shutting down the generator at 21:00. The Killdeer, as usual arrived after dark.

The diverse temporal use of the Ecological Reserve by different species would be missed in a standard count where the observer passed through during a set amount of time. By having an Eco-Gaurdian here throughout the day, a much more thorough accounting of the different species use of the Protected Area is possible.

Here are the results of the animal census:

Friday’s weather was windy and wet. There was a lull early, as it switched for a short time to southwest but then turned back with a vengeance to strong northeast and big seas. The forecast is for a switching back and forth from southeast veering to southwest and back. It is blowing north 24 knots as I post this Friday evening, but is supposed to come down to light variable in the morning, rising againSaturday afternoon.

One whale watching vessel used the Ecological Reserve today and like yesterday’s boats, it too ventured into the danger zone of breaking reefs on the south side. The ebb was so large at the time that there were standing waves and a huge overfall along the string of rocks, islets and shallows. After a few tippy moments, they got out of there and I was glad they were all safe and sound.

I fought entropy today doing a few minor cleanups, making kindling and moving propane tanks around (downhill and empty). The usual chores also kept me busy. I tried to figure out what is going on with the camera, which has not yet fully cooperating. Now that I am through the technical barriers and able to post the blog I will be doing so daily and hope to post photos soon.

  • Cleared logs off the ramp two times.
  • Lowered the boat trailer because the cable coil was quite criss crossed. Managed to recoil the cable in a more orderly fashion.
  • Vacuumed up hundreds of fruit flies in the basement near the composting toilet.

Boats

  • Alex and Virginie left in the morning.
  • Surprised to see no eco-tourism boats about on such a nice Sunday.

Ecological Happenings

  • Storm warning with high winds overnight and gale force in the morning. Overcast with lashing rain at points.
  • Small Harbour seal pup seen on the boat ramp first thing.
  • Surf Scooters seen to the south of the main island in the afternoon.
  • The Bald Eagles were seen buzzing flocks of gulls and cormorants on the rocks, driving the gulls into the air and the cormorants to sea. The gulls retaliated by mobbing the Eagles in the air and driving them off.
  • The female Elephant seal was absent this morning and did not return all day. The smaller Elephant seal seemed like it was looking for her through the day. The males barely moved and snoozed through the storm.
  • Sea lions rafted together and played in the surf jumping clear out the water at times.

Marine Vessels

  • None

Maintenance

  • Jetty cleared of driftwood from yesterday’s storm.
  • Logs at the student house re-stacked as they had been blown over in the high winds last night.
  • Pressure washer pump lubricated and reassembled.

Ecological Happenings

  • A generally bright day with gentle winds and calm seas.
  • Significant quantities of driftwood have been washed up including large sections of telegraph poles and tree roots.
  • The elephant seals seem to be here for the duration. Though their route off the island (boat ramp) has only just been cleared of driftwood.

Marine Vessels

  • One whale watching tour in looking at the sea lions and birds. Good speed through the reserve, though at times strayed too close to animals.

Maintenance

  • Solar panels cleaned.
  • Maintenance routes of the energy centre roof scrubbed clean of slimy algal build up.
  • Boat ramp and jetty cleared of driftwood washed up in the last few days of strong winds and rough seas. Derik used to lift larger logs up for drying and cutting into firewood.
  • Windows cleaned on the main house.

A Stormy Census

Ecological Happenings

  • A Stormy day on the Rock with Gale force winds and large swell running.
  • Sea lions rode out the winds in the ocean swells, rafting together in large moving masses or surfing in groups.
  • The two Bull Eseals stayed on the island.

Marine Vessels

  • Navy vessel on manoeuvres outside the reserve.
  • Accompanying Navy helicopters flying out from the ship over the reserve at night.

Maintenance

  • Some driftwood cleared from the boat launch ramp after the winds dropped.
  • Camera 2 re-set. Further investigation needed to resolve the network problem.

Other

  • Number of animals in the reserve was affected by the storm (and maybe the counting too due to conditions!).

It was a beautiful day at Race Rocks, with light southeast winds and a mostly clear sky. The barometer fell a little today to ~1013hPA and the forecast for tomorrow is for sunny skies. There is a strong wind warning in effect for overnight with diminishing southeast winds Friday. Rain is forecast for Saturday.

Only four whale-watching vessels were noted in the protected area today and three pleasure craft passed through going slowly. The people on one of those vessels, the Kaos were observed feeding rockfish to sea lions in the Ecological Reserve. It is illegal to feed wildlife and if it happens they will be reported.

Today was animal census day and here are the results.

Don and Nina, the new eco-guardians in-training arrived today. They worked hard all day, after getting up very early to catch the morning slack and are progressing really well in learning some of the idiosyncrasies of Race Rocks operations.

Twofold Foggy: Friday – Saturday

Friday started with fog again and light southeast winds, from 5 to 10 knots. By late morning there were glimmers of clearing and by mid-day the sun was shining. The wind stayed calm and it stayed fairly clear, with clouds rolling by as the wind turned to west, in the late afternoon. By evening it was still and the sky mostly clear but that must have changed as the was fresh rainwater in the morning. The barometer bottomed out Friday morning at 1007 hPA before rising briefly. It started to drop again mid-day falling until mid-Saturday. The gale warning for Saturday, came true after another very foggy morning and light easterly winds. The turn to westerly was rapid, the fog was blown off and ominous clouds with a black line on the water to the west, foretold of what was to come. It blew up fast, reaching 40 knots and then settled back down to the up and down of 20 – 35 knots. There is gale warning is still in effect and the wind is forecast to lighten overnight, then become easterly 5 to 15 near noon Sunday. (I am collecting rainwater for laundry, bonus.)

Only two whale watching vessels were observed in the protected area Friday. Two sports fishing vessels also passed through. Saturday was a little busier with five whale watching vessels noted in reserve but there were no pleasure craft, they were probably seeking shelter. It is quite possible that I missed traffic both days due to thick fog reducing visibility.

Thursday was too foggy to do the animal census so it is cobbled together from the brief time slots when visibility permitted on Friday. It is interesting to note that the gull population plummeted after the arrival of the first Bald Eagle to be seen here, since I arrived at the end of August. Not sure if that is coincidental or not.

I only noticed the eagle because of the hundreds and hundreds of gulls moving en masse, from North Rock over to Great Race. When I peeked through the spotting scope, all the cormorants were in the water, the gulls were gone and there sat an adult Bald Eagle. Only the Harbour Seals seemed to ignore its presence.

There was no sign of the eagle today and the gull numbers are perhaps even lower. Glaucous-winged juveniles and adults continue to mill around summer territories. Some young ones are still practising picking things up, flying up and dropping them. Most of the adults are fully into their alternate plumage now. Their faces recovering from the physical aspects of feeding young.

The sea lions are spending more time in the water now that their favourite haul-out spots are worse than pig pens. Some of them have turned to rock climbing and I saw the first scouts up on the heli-pad today.
