A Quiet Day (Except for the Explosions)

As predicted, winds were light today, starting in the southwest, then switching to west, 5 – 15 knots. Although it was sunny, there was a real nip in the air first thing. The barometric pressure continued its slow rise today, reaching 1025.5 before steadying. Tomorrow’s forecast calls for more sunshine and a low of 2o C, while and winds to switch to east, 20 – 25 knots.

Several whale watching boats visited the Ecological Reserve today, stopping by South Rocks to see the sea lions and eagles. It was a beautiful day to be out on the water. A few sports fishing boats passed close by and fished outside the Protected Area. There were more explosions from across Race Passage today and it was unusual that they continued after dark.

Images of sea lions sleeping on South Rock before and after an explosion can be seen below. Three branded sea lions were photographed today; two California Sea Lions #U68 (brand on posterior) and #8240 (brand on left side) and one Steller’s Sea Lion #42DY.I remember #8240 from last fall but had not noticed him until today during this shift. There appear to be more sea lions daily.Tomorrow is census day. At dawn this morning, Alex noticed a small seal, possibly a Northern Elephant Seal and a Sea Otter on the ramp.

Forage fish were active at the surface again today; guessing that they are herring are on their way back out to offshore habitat after spawning. The fish attract the fishers and by late morning there were three adults and 12 juvenile Bald Eagles in the Protected Area. They favour sitting in large groups on South and West Rocks but they also use Great Race in a more solitary way. The Canada Geese seem to be staying away and the large number of eagles may be deterring them from feeling comfortable on Great Race.

Harlequins continue to astound and inspire with their gorgeous plumage and amazing diving abilities. All three species of cormorant Pelagic, Brandt’s and Double Crested were busy in the Ecological Reserve today. It appears that they like to forage where there are convergences and upwelling. They dry their feathers, roosting in the wind and sun on the west end of Great Race, Turbine and Middle Rocks.

Chores were routine today.

 

Back to Westerly Gales

Weather-wise, yesterday was wild weather and today dramatic. After yesterday’s log was posted and the internet was out,  the wind turned to southeast and sustaining over 50 knots. The barometer bottomed out at ~987 hPa  in the early hours of the morning and then started to rise again. As today’s entry goes on the web-site ~17:00 it is at 1006 and climbing.

This morning, the sea was still in motion with a substantial swell (~1m) from the southeast that was knocked down later by the flood tide and west wind. The wind switched to west fairly early in the morning and it has been blowing 20 – 30 knots all afternoon. (Oh for a wind turbine that doesn’t harm birds.)

The forecast for Friday is a switch to east overnight, 5 – 15 knots, turning back to west 10 – 15, by late afternoon. Showers to continue.

No vessels were observed in the Ecological Reserve today. Explosions resumed around noon, with the red flags flying a warning to all.

Geese are starting to prefer Rocky Point’s grassy areas and that is a good thing. The high density of eagles here could be unsettling. A Bald Eagle was observed taking a cormorant today. The big adult ate about half of it. Another slightly smaller, adult (male?) approached, waited and they switched off carefully in the wind so the carcass would not fly off. The male (?) ate most of the rest, before taking off with remains in talons, as gulls moved in to clean up. There were a few different species gulls resting here today. The Harbour Seals didn’t show up yesterday or today, nor did the Pigeon Guillemots.

One tagged California Sea Lion was photographed; tag and brand # X79. A necklaced Steller’s Sea Lion was observed and photographed. It look a lot like one that was here last fall except that the plastic on the neck may be coming apart. The animal is vigorous. While under observation, it climbed off one rock, swam across head held high and climbed up another rock, to the top of the ‘dog pile’.

Today was census day and here are the results.

Wild Goose Chase

Last night’s north easterlies created a bit of a symphony: percussion on soffits accompanied by back door whistling its multifarious tunes. Morning started with the call of Canada Geese arriving, southerly winds (10 – 15 knots) and rainy skies. By late morning the wind direction had changed to west and the sky eventually cleared to a mix of sun and cloud by late afternoon. The gentle to moderate westerly is forecast to continue tomorrow bringing a 30% chance of showers. The barometer has been rising all day, so things are looking up.

‘Sports’ fishers were seen passing and fishing in the distance today and there were no sightings of whale watchers in the Ecological Reserve.

I went out to clear off the geese first thing and saw a pair mating in the water. That inspired me to ramp up daily goose patrols. No sign of nests yet, but there are a few pairs that are hormonally persistent. The large number of Bald Eagles is potentially helping keep the geese nervous. I saw an adult eagle flying with some sort of large bird, hanging from its talons but could not tell if it was a goose or a cormorant. The gulls seem to be setting up their territories, even though it still seems quite early for anything very serious. Pigeon Guillemots, Glaucous-winged gulls, and Black Oystercatchers are all in breeding plumage, as are many of the three species of cormorant.

Chunk actually moved today, leaving his dead, stink zone for fresh flowers and a sloped recline on the other side of the paths. I also saw him open one eye as I walked past, a small feat of energetic response. He really is wiped out from all of his male activities.

A California Sea Lion, which is equally lethargic, is hauled out beside the derrick and he looks quite emaciated with backbones and ribs showing. The rest of Sea Lions that remain look healthy and haul out tightly together in two spots, a small group just down to the northwest of the Science House and a larger group on the South Islets. There are a few branded animals but I haven’t been able to get photos yet. A male Steller’s 76Y (left side) and a couple of rump branded Columbian California Sea Lions. 76Y was branded at St. George Reef in northern California, just south of Oregon, in 2002 as a pup. 443Y is just going into its third year and was branded at Rogue Reef in southern Oregon, just north of the California border, in 2013.

 

There were no visitors and chores were routine.

 

 

 

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.

First Official Day On The Job

After training last weekend, and a general review yesterday, I, Riley Strother, have now taken over as Ecoguardian from Alex Fletcher.

Weather

  • Visibility: 15 miles
  • Wind: 15-20 knots NE
  • Water: 1’ chop
  • Sky: overcast

Ecological

  • The first female elephant seal to give birth left the island at 7:30 in the morning and did not return. As such the first pup has now become a weaner.
  • Chunk appeared to mate with the female who lost her pup.
  • The newest pup is quite vocal and seems to be doing well. Chunk and the other female went along the path after mating to inspect the new mother and pup.
  • Alex was able to identify the number on the yellow flipper tag attached to the newest mother: 5928
  • There was quite a disturbance of seagulls and cormorants today when a raven with a small fish in its beak was chased all around the island by two eagles. Eventually the raven managed to land and eat the fish.
  • Conducted a census.
  1. California Sea Lions: 88
  2. Northern/Stellar Sea Lions: 53 (many sea lions were swimming in the waves and thus impossible to count)
  3. Elephant Seals: 8 (Chunk, weaner, grieving mother, new mum and pup, Middle Rock: Chuckles, mum and pup.)
  4. River Otter: 1
  5. Cormorants: 615
  6. Seagulls: 512
  7. Bald Eagles: 9 (7 juvenile, 2 adults)
  8. Raven: 1
  9. Crow: 1

  12. Canada Geese: 6
  13. Black Turnstones: 29

Maintenance

  • 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.
