Mirounga Manicure

Posted on by

The west-southwest breeze sprang up early and quickly cleared the low morning cloud, revealing blue skies and a rippled Strait. With a sustained westerly wind of up to 20 knots the ripples grew into chop with whitecaps by mid-morning. It continued to blow in the afternoon rising to a steady 30 knots with gusts over 35. By early evening with the wind relentless, it is rough and streaked in white.

The barometric pressure, that harbinger of weather, slid almost imperceptibly downwards today, yet the forecast for tonight and tomorrow is for more west winds in the same pattern. There was increasing cloud throughout the afternoon.

There were no whale watching boats observed in the Ecological Reserve today and only one sports fisherman who sped through the ER, cutting over to the southwest, his favorite anchorage spot to fish for halibut, just outside the closed area.

The Northern Elephant Seals have moved to a more convenient spot behind the boathouse, which is closer to the water and more in the lee under the heli-pad hill. The moult continues.

It is fascinating to watch the elephant seals use their digits and make what looks like a fist in a mitten of freshly moulted skin and fur.

Many pairs of gulls are mating now and I observed a pair of Black Oystercatchers doing the same. Some of the oystercatchers may already have eggs. I am taking clues from the raven that frequents the island and is always interested in a couple of pairs’ territories. The raven really riles up the oystercatchers, who fearlessly mob it. It was so windy today that while the chase was on, the raven tried a tuck to avoid being hit by an oystercatcher and almost lost control.

 

The eagles were fishing early but left when the winds came up. The photo below finishes the series I started a few days ago, to show how the eagle tucks the fish up under its tail in flight.

Fine Day in Spite of the Forecast.

Posted on by

Light northeasterly winds brought some morning showers and kept it cool until late morning. The light northeasterly continued in the afternoon but solar radiation levels went up to a high of over 800 watts per m2 bringing up air temperature to a high of over 13oC. The barometer was fairly steady until noon and then started to fall very gradually. The marine forecast has a strong wind warning in effect overnight diminishing to a 20 knot westerly by early afternoon tomorrow. As I write this in the early evening the north-northeasterly is freshening to over 20 knots.

Three whale watching vessels were observed in the Ecological Reserve today… Sports fishing vessels were observed fishing nearby but not in the ER.

More measurements and individual moult progression, observations were made on the Northern Elephant Seals on Great Race today.

The Day After Blue Planet Day

Posted on by

Winds started out very light from a northerly direction and eventually backed all the way through east, southeast and around to westerlies, 15 to 20 knots and gusting, in the afternoon. Although there were some clouds and showers it seemed to be a nice day, but when you look at cumulative solar radiation values they were less than half of yesterday’s values at just below 300 Langleys. The barometer fell gradually all day and levelled out near dusk ending up at ~100.5 HPa. The strong wind warning remains in effect and is forecast to be strongest in the afternoons for the next few days.

Whale watching boats were back today after the storm subsided and four were observed in the Ecological Reserve. They were meeting and exceeding the Marine Mammal Regulations and although a couple of the smaller cowboys did manage to get between Great Race and South Islands. They were going so slowly and cautiously that the sealions that didn’t even wake up as the boats passed by.

No sports fishers or other vessels were observed in the ER.

All About the Wind.

Posted on by

The west wind blew all night and by daylight, the 30 to 35 knot winds had sucked in low cloud, rain and rough seas from offshore. Winds increased to 35 gusting to 40 knots in the late morning and continued unabated all afternoon. Air temperature was close to yesterday’s sea surface temperature of 9.7 o C and with the wind chill was hovering around 4oC. Light levels were the lowest of the last week and not even 60% of yesterday. The barometer bottomed out just before midnight last night and has been slowly creeping up and out of its hole today. Gale warnings remain in effect for tomorrow with the wind predicted to turn southeast Thursday.

The only thing not affected by the wind today was the stone tower.

There were no whale-watching tour boats in the Ecological Reserve today. Sea conditions were not conducive.

The ecological focus today was to observe how the mega-fauna behaved in the wind. Only a few sealions hauled out, the remainder rested in the water near the haul-out where it was probably quite a bit warmer without the wind chill factor.

This is a day when having blubber really makes sense.

The Northern Elephant Seals made a huddle and “took turns” being in the coveted central, heating position. One female slept off by herself, maybe not quite as warm but definitely more peaceful. Only #5850 went for daily ablutions, the others stayed dry, even if a bit mucky.

Glaucous-winged Gulls hunkered down with heads under wings, keeping a low profile and perhaps holding on with their toenails, as they seemed to totter and grimace during the big gusts. The geese with nests were on them with ganders close by guarding and staying low. The three pairs that are still trying to set up nests were observed chasing gulls . The Bald Eagles, so ubiquitous every other day for the last 25 days, were nowhere to be seen, nor were oystercatchers, turnstones, nor guillemots.

Two marine science classes were supposed to visit today but the weather just didn’t cooperate and Courtney wisely cancelled the trips. Thus there were no visitors and chores were basic routine.

 

 

Beautiful Spring Day

Posted on by

The wind didn’t do much until mid-afternoon when the westerly came up and blew 10 – 15 knots. Velocity kept increasing during the afternoon and evening and as the sun was setting it was blowing a steady 30, gusting to 35 knots. It was a very sunny day with 354,000 watt-hours per meter2 accumulated throughout the day. The barometer continued its slow descent begun on Saturday and is heading inexorably towards wet weather in the forecast. Although it is still supposed to blow west tomorrow, with showers, the rest of the week looks darker and wetter.

A couple of whale watching boats were observed in the Ecological Reserve today: both were proceeding with caution, at a minimal speed and staying a respectful distance away from the wildlife. These companies are practicing sustainable wildlife viewing practices. One rental boat was observed speeding in reserve.

The Northern Elephant Seal moult continues and is becoming more visible on the older animals. The measuring device was modified to allow for more accurate length measurements and the animals continued to cooperate by going one by one, down the ramp and into the sea for a swim. #5850, the young male tagged as a weaner in 2012 was stretching bull kelp stipes today, a biomechanics activity done by phycology students everywhere on the west coast. No teeth involved, so no confounding tearing factor.

Smokey Skies

Posted on by

The wind was still, early this morning. It didn’t really start moving until mid-afternoon, 5 – 10 knots from an east-southeastly direction. Although it was sunny, there was a haze in the air that made for a blazing sunset last night and sunrise today. I am curious if this is smoke, all the way from Squamish, where there was a big creosote wharf fire a few days ago?

Are these red skies in the evening and the morning a result of the Squamish wharf fire?

The barometer rose slowly until about noon and then it started to slowly fall, nothing dramatic and no strong winds. The forecast is for more of the same, with afternoon westerlies tomorrow.

Three whale watching boat were noted in the Ecological Reserve today. The last whale watching vessel of the day, idled slowly through, keeping a deferential distance away from the animals, Tourists were out on the bow, shooting pictures of the blazing sunset and lounging marine mammals. It was a tranquil scene. No sports fishers were observed either speeding in the Ecological Reserve or fishing in the closed area, although several passed through at speeds respectful of the wildlife in the area.

Passive Northern Elephant Seal data collection continued. As luck would have it, all seven animals that had been sleeping in the garden, woke up and decided to go for a swim late morning. This allowed me to take their photos as they passed by the measuring device. I was also able to get some photos inside mouths for dentition information while they were wallowing around gargling saltwater and ‘wrestling’. Tagged animal #5850 continues to hang out as one of the seven ‘gardeners’.

Dentition changes with age and can be a health indicator. Say ah.

There are still three pairs of Canada Geese trying to establish nest sites and they are having a hard time finding territories on this tiny island that already has at least nine Canada Goose nests. Maybe they will head over to Vancouver Island where there is more room. Their territoriality can get in the way of other species having a piece of the very small island as they chase off, not just each other, but Glaucous-winged Gulls, Black Oystercatchers and Pigeon Guillemots.

There were no visitors today. Maintenance chores were routine.  About 9:30 PM the phone/Internet went down for the seventh time since I arrived. Even that is becoming routine.

A Stellar Day

Posted on by

Calm seas, sunshine and light winds combined to make it a very pleasant day. The wind really didn’t do much and direction changed throughout the day from west to southeast and back again. There was enough sunshine  to power the solar panels, run the de-salinator  and build up the batteries. The barometer declined slowly all day after a high start and the forecast is for a mix of sun and cloud tomorrow with a strong westerly winds predicted.

Two whale watching boats used the Ecological Reserve today.   From where they were, I am guessing that they enjoyed the pinnipeds and sea otter as well as the birds. Several sports fishing boats transited through at high speed and one fished close to the boundary.

Female Steller’s or Northern Sealion #334R was photographed today. She was branded as a pup in July 2003 at Rogue Reef in  southern Oregon.

The Northern Elephant Seals continue to grace Great Race and I am getting used to them not reacting at all to my presence on the walkways.

The Glaucous-winged gulls are starting to mate and gather nesting materials. The Canada Geese are busy defending territory and brooding eggs. Black Oystercatchers are likewise busy when not foraging in the intertidal where limpets seem to be their favourite food.

April 12

Posted on by

As the sun set, the wind shifted around to south-southeast after blowing about 10 knots  from a westerly direction most of the day. The snow line across the Strait is very low and the chill in the air continues. Although there was some sunshine today producing a high solar radiation reading of 1,000 watts/m2, there was also a lot of cloud. The barometer reached a high of 1020 hPa mid-day and then began to fall. The forecast is for southeast showers switching back to westerlies tomorrow afternoon.

Only one tour boat was observed in the Ecological Reserve today and although there were dozens of sports-fishing boats all around the reserve none were observed inside.

American Pipits have been spotted bobbing and flitting around Great Race and there is a photo below as evidence. Thanks go out to Rocky Point Bird Observatory for the identification confirmation.

Six Northern Elephant Seals came ashore at first light and spent the whole day sleeping in the garden. One was a tagged, with a pale green tag #5850. This same individual had two tags when I first saw it last fall, October 14.

The Glaucous-winged Gulls are engaging in more definite pairing behaviours and also becoming more territorial. Many are nest building, pulling out chunks of grass turf for padding. Black Oystercatchers are looking broody too and I observed Black Oystercatchers eating limpets today.

Dawn broke in reds and pinks heralding another glorious day. Early on there were feeble zephyrs from the southwest and east but the most obvious wind tell-tale on Race Rocks, the Canadian flag, hung limply most of the morning. Westerly breezes started in the early afternoon and developed into moderate breezes, late afternoon with gusts to 23 knots. The strong wind warning forecast is downgraded now to 15 to 20 knots westerly, overnight in the central Straits of Juan de Fuca and it is already dropping, as the sun sets.

No tour boats were observed in the Ecological Reserve although one hardtop sport-fishing boat cruised past the sea lions at a respectful distance and speed.

A Northern Elephant Seal visited the marine railway for a snooze on the falling tide this morning. It was a perfectly symmetrical ellipsoid. From the light tower another 16 elephant seals could be seen on Middle Rock. Two more in the shallows of Middle Rock, looked so much like smooth rocks draped in seaweed, that they had me fooled for a while. That makes 19 in total, a high count for me so far.

There have also been a lot of Bald Eagles present with a total of twelve individuals today. I have been trying to figure out what they are eating and have seen them chasing both gulls and geese.

I have also seen some casualties, including three gull carcasses but they do not have the look of eagle food. The one in the photo above is completely pristine even after several days, with no trace of blood or predation.

This evening the eagles caught and ate something but I could not tell what it was, there were no feathers at the site where they were dining but it may have been turned inside out (skinned). Four adults and two sub-adults fed off the one carcass.

Alex continues to be my only visitor and we had a belated Easter dinner, highlighting delicious, fresh halibut. I wonder when the last time was, this kitchen had freshly jigged halibut? Alex resurrected a bench that was both broken and had missing parts. It now sits in front of the Science House with a view out to sea and east up the Strait.

The phone and Internet went off again last night and I didn’t realize it until late. The problem was different this time and required a UPS reset in the tower this morning. I am getting quite adept at restarting the weather system now and we also tried (again) to fix the wind direction indicator on the system. I had success getting the underwater camera going again but it really needs a good scrub. The desalinator filled up the water tank again, running on sunlight through the solar panels. I cleaned up the visitor sign-in cabinet a little and put in some fresh pamphlets about how the public can support Race Rocks through Pearson College.

Note this blog posted next day due to yet another failure of phone/Internet last night due to UPS overload in tower.

April 4th – Full Moon and Blood Moon

Posted on by

The weather was much more subdued today with light winds and a morning switch in direction to the east, northeast and then back to westerlies at sunset. The sky was partially overcast but more sunny than cloudy with only the slightest of showers. The barometer continued its very slow and not very steady, decline that began on Thursday. The forecast is for more of the same. Today’s full moon was in total eclipse early this morning and although I was up at 5:00 AM, I did not see it, maybe that is because it was totally eclipsed ; – )?

Only two tour boats were noted within the Ecological Reserve today and they both kept their speed down and seemed to be very respectful of the wildlife. There was no fishing activity noted inside the Conservation Area.  A couple of Kayakers were paddling in the Ecological Reserve today and they were very close to the sea lions. They managed to make it past them without any disturbance, but the sea lions woke up after the kayakers passed. They were only concerned enough to do some neck craning and alert behaviour before falling back asleep.

Ecologically things were very much like the previous two days, the gulls are slowly becoming a little more territorial and parental looking. I saw two holding nesting material in their bills today and several pairs were doing a synchronous bill down dance that might demonstrate to the other how beautifully they will be able to regurgitate into any chicks they might produce together. I also witnessed some nasty bill holding that drew blood and descended into an outright wrestling match. I was not sure if these gulls were territorial competitors or mates but they were determined to not let go of each other. Gulls are supposed to mate for life so it makes me wonder, when I see the same gulls sitting poignantly all alone, on their spots, day after day. Is their mate missing in action or just late?

The Canada Geese are very broody and in some places are running the gulls off. Some geese are already incubating four to eight eggs per clutch.  I guess the crows know this and there is often a small murder of crows strutting around the nesting areas and also being chased off by the geese.

The Bald Eagles are here all day everyday right now and I watched one adult chase off another so there must be something good to eat. Is it gulls? The chase was quite spectacular with climbs and dives and at one point, upside-down flying in self defence. The defeated intruder headed over to Bentick Island.

It wasn’t sunny enough today to just go with solar power and I had to run the generator for a couple of hours in spite of having no extra draw on energy. I know the day is coming when there will be enough sunshine to go through a whole day, entirely on solar power.

Thirteen visitors came to the island today. Chris brought out a group of eight students and his son accompanied him with a school friend. Alex was deckhand again and brought his father who was visiting, along for the brief version of the Race Rocks tour. Alex’s Dad likes using the Race Rocks video cameras, so one more reason that I need to figure out how to get cameras #2 and #5, back up and running. The students will go back mid-day on Monday and are already earning their keep.

Chores were a mix of entropy fighting of  today. It was really nice to know that there is lots of water in the midst of churning compost and the usual tasks. I am still tidying up wood and very grateful to Alex and Virginie for all the firewood and lovely kindling. I also want to thank Nick for leaving the house so spick and span, very nice.
