Green with Shades of Blue

March 17 was a windy day on Race Rocks. The early morning east northeast wind  kept intensifying and it was blowing 25 – 30 knots northeast by noon. It kept up for the rest of the day. The barometric pressure started to drop from a high of 1026 hPa, in the afternoon. The forecast includes a gale warning, with the easterlies continuing under sunny skies for at least tomorrow.

One whale-watching vessel was observed working in the Protected Area today and several others were seen transiting the area. Sports-fishing boats were all outside the reserve.

The Nanoose Yarder, a tug, headed west through Race Passage with the fishing vessel, Arctic Fox II in tow. The Arctic Fox II was damaged by fire in Cowichan Bay last winter and looks like she will need some serious TLC before heading out again to troll for tuna, offshore. DND blasting continued.

The impression that the gull population was rising daily, returning en masse was not wrong. Nest site locations from last year are almost fully occupied. Pairs are standing close, pulling vegetation and starting to jockey for position with neighbours. No actual nest building has been observed yet. Canada Geese have been discouraged.

The idea that more California Sea Lions were showing up was backed up by more brands observed today and of course by the counts themselves.  Today was animal census day and results are posted below.

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.

 

Under way on Nuclear Power

There was a large roar made by ocean swells breaking and surging on the west and southwest sides of the island, at first light today. Winds abated and light southwest to west winds in the morning turned to light west in the afternoon rising to 15 to 20 knots by evening. The sky cleared by noon and stayed that way until dusk. The barometric pressure continued Monday’s trajectory, rising above 1022 hPa by mid-afternoon and holding there into the evening.. The marine forecast calls for light winds Wednesday and a few days of sunshine.

Four whale watching vessels were observed working in the Protected Area today. All four vessels went around to the outside (south) of South Rock to observe the seals, sea lions and eagles. One sports fisher was observed travelling through the reserve and dip-netting fish near the Rosedale Reef buoy. Forage fish, possibly herring seemed to be boiling up to the surface their drawing numerous eagles, gulls and cormorants.

An Articulated Tug and Barge (ATB), (barge, a loaded oil tanker), was noted outbound, this morning. When we checked for a vessel name on the Automated Information System (AIS), http://www.marinetraffic.com/en/ais/home/centerx:-124/centery:48/zoom:10 it did not show up on the marine traffic system neither did the tug attached to it as a pusher.

A report to the BC Ministry of Environment on the risk of oil spills in BC waters (http://www.env.gov.bc.ca/main/west-coast-spill-response-study/)states that barges are not required to use AIS however their tugs should register. The report goes on to say that a spill from an ATB could exceed 25,000m3 of oil. Fuel barge movement statistics provided by Canadian Coast Guard Marine Communications Traffic Services to the 2013 BC report show over 1000 fuel barges outbound from Victoria, Vancouver, Comox and Prince Rupert and another 514 transiting Victoria alone. Why are they not required to register? There have been several near-miss incidents with these oil carriers; why not use every means possible to maximize safety and reduce risk, such as AIS?

To put things in context, a show of force was led by the USS Shoup heading out to sea, followed an hour later by a very large submarine escorted by a convoy bristling with military might and expense. The usual explosions from Rocky Point put the ar in arsenal.

Ecologically, the gulls are becoming more abundant and settled in their nesting spots. Territorial disputes are a daily occurrence now as are the calmer moments of pairs just standing together gazing at and grooming each other. The Harlequin Ducks have been busy with all the whitewater activity and take their rest on the boulder beach just southeast of the main house. Pigeon Guillemots were back for a morning visit to Great Race.

Sea lions and Harbour Seals had really good daytime sleeps today recovering from the storms.

Temporary repairs were completed on damaged roofs, as was clean-up and mopping up from the storm.

Rest and Recovery: The Lull

Friday and Saturday were both calmer days, with light winds and a mix of cloud and sun. The barometric pressure dropped slowly all day Friday and then wobbled back up today to ~1001 hPa where it holds as this entry is posted at 19:00. There is a warning for central Juan de Fuca Strait, calling for ‘Gale’ force winds of 34 to 47 knots east to southeast. At dusk there were large thunder clouds dropping heavy rain, moving towards Sooke.

With the warning in place and the last storm a fresh memory, there were few small vessels seen on the horizon yesterday and today. Only two vessels were observed within the Ecological Reserve boundaries today. One was a speeding sports-fishing boat heading for Victoria. It passed remarkably close to the small reef that just shows above the surface, west of North Rock. The other was also a sporty boat equipped for salmon and halibut. It passed through Middle Channel very slowly, against the flood.

The Strait was busy with marine traffic including four RoRos, (roll-on, roll-off, car carrying vessels with a capacity of ~6,000 vehicles each), in a steady procession outbound. The cable laying ship was inbound as was the tanker Argent Sunrise amongst many others coming and going.

On Great Race, the Glaucous-winged Gulls are back in force, pairs occupying their favourite spots in shiny new plumage. The gull count today was 340 including ~25% juveniles and an estimated 125 paris of adults. One Western Gull and a few California Gulls were amongst the mix. Every time a bald eagle passes over, all the gulls lift off as though raising their collective hat in respect. The two birds observed killed by eagles, to date, on this shift, were both cormorants. They are not such skilful flyers as the gulls and probably easier to pick off.

Harbour Seals missing in action during the last census; have returned to their haul-outs and today’s count was 97 individuals. The Pigeon Guillemots returned this morning as well (~75) but were all gone by early afternoon.

Remnants of the heritage lighthouse gardens are blooming everywhere right now and the rich green growth is a draw for Canada Geese.

Went ashore yesterday for first time this shift. Picked up Alex and supplies. The visit is timely on many fronts. Chores were much more than routine today and it is really great to have good company.

 

 

 

 

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.

Chores were routine and there were no visitors.

Eagle Food

There was nothing remarkable about the leaden morning with light and languid, north-northeast winds. Partially overcast skies cast a silvery pall over the Strait but bits of blue sky held promise for better things to come. The barometer held overnight at just above 1010 hPA and by mid-afternoon had dropped to 1008 As evening falls the barometer is holding at 1007. In the afternoon there was some sunshine but it was really a day dominated by cloud.

Five commercial whale-watching vessels were observed working in the Ecological Reserve today. Three were seen working in behind (south side) South Rocks and they were travelling very slowly and cautiously. Sea conditions were calm. The sea lions did not appear too disturbed by their presence. A few younger animals close to the water went in but it would be difficult to determine cause. On that note, military blasting continued as planned, from late morning to mid afternoon. Interceptor vessels and red flags warned boaters off. The sea lions and birds did not seem to react.

The wild goose chase continued and progress is happening. By early afternoon, most of the geese had retreated to the military zone to graze on the large lawn there. One pair staking out an area by camera 5 were more persistent, but eventually left for greener pastures. A couple of pairs of gulls were seen doing some of the broody things they do when nest building but as it is early yet, they are probably just practicing for the big day when they actually start to build a nest. The Pigeon Guillemots continue to flock here in the morning and leave in the afternoon as noted by Riley. Many were practicing walking on land today and in the water they worked the ebb flow through the rocks taking a ride and then flyew back upstream for another one.

A partially decomposed Northern Elephant Seal pup and part of its skull was located not far from the octopus in the boulders beach east of the Ecoguardian’s house. From the size, it appeared to have been a very young pup, if not premature, at death. The octopus was bigger. The plentiful, rich food sources are starting to explain the large number of eagles here daily.

A branded Stellers Sea Lions was photographed today 319Y and 4332 was observed. A California Sea Lion with a number on its rump and an X anterior to that was observed but the number was not verified nor was a successful photo taken.

 

There were no visitors and chores were routine today.

 

 

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.

 

 

 

Blue Sky Grey Sky

It was a blue-sky day at Race Rocks for most of the day, as the wind switched from west to northeast and then finally greyed over. The wind started light in the morning and rose to 36 knots NE, by late afternoon. The barometer climbed out its early morning hole of 993 hPA and dove back in as night fell. As I post the log it is falling past 989. The forecast is calling for the wind to drop and switch to southwest 15 to 25 knots Sunday afternoon and to light Sunday evening.

Four whale watching vessels were observed in the Protected Area today. They seemed to be travelling out to the west probably in search of migrating Gray Whales. They were a little more cautious on the south side, a trend, which tends towards sustainability.

The “sporty” halibut fleet was out fishing today. They anchor for the slackest part of the tide, spaced out like a beads on a necklace around the Ecological Reserve. Not all of them know about (or they choose to ignore) the ‘no go’ and ‘go slow’ limits of the Protected Area .

The reasons for speed limits in the Protected Area are the high density of marine mammals and birds and the location’s inherent dangers. Going slow protects the wildlife from boat strikes and reduces disturbance if boats stay far enough away. The no go areas also extend that protection to human life. I am not sure how many people have died in the waters around Race Rocks, but if it were a road intersection, it would have one of those high crash scene signs, combined with a wildlife crossing sign. I look forward to the day when boaters know and respect the rules. The quickest way for that to happen is by word of mouth and peer pressure. So if you boat in the area, please feel free to give others a friendly ‘reminder’ about the rules You might save their life. For the professional mariners, it is a very important part of being professional.

Chunk, the only remaining Northern Elephant Seal continues to slumber in the same spot. He has completely fried the vegetation where he is stretched out and seems to have lost a lot of mass since I saw him last fall. I guess he has been fairly engrossed with breeding, killing pups and fighting with other males. It must soon be time for him to head off and bulk up in the depths. He has massive “stretch marks” from slimming down to what looks like about 50% of his portly, fall physique.

There were a dozen Bald Eagles here today and the cormorants roosted on Great Race so it was possible to see the subtleties of the neon blue under the Brandt’s Cormorants’ chins and their whiskery white feathers.

The numbers of Canada Geese have risen rapidly, going from six, the day I arrived, to twenty by this afternoon. Canada Geese are protected under the Migratory Bird Regulations, however, they can wreck havoc on a tiny islet like Great Race, which is also used by other species that cannot easily, (unlike Canada Geese), nest elsewhere successfully. Like some people, they are loud, pushy and tend towards aggression, not making the best neighbours for nesting Black Oystercatchers, Pigeon Guillemots and Glaucous-winged Gulls. Although the status of all three of these nesting species, is ‘Least Concern’ as listed by the International Union for the Conservation of Nature (IUCN), we are hoping to keep them that way and discourage geese from staying (under strict permit from Environment Canada).

Other than wild goose chases, chores were routine today including camera and computer care.

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.
