Mirounga Manicure

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.

April Almost Gone

The wind didn’t do much today other than puff a few light breezes in from the west with a few periods rising to 5 to 10 knots. It was mostly overcast with a few bright interludes and generally rather unremarkable in terms of weather. When the sun did shine through it had intensity foretelling the growing season. The barometer was fairly steady all day and is just starting to drop as I write this. The forecast is for a mix of sun and cloud, a chance of showers and a strong wind warning in effect for Friday afternoon.

There were nine whale watching vessels observed in the Ecological Reserve today, a bit of a spike, possibly due to a large cruise ship at Ogden Point.

I watched a Harbour Seal tearing up and eating a fish today. It looked like it might have been a lingcod (Ophiodon elongatus).

This female elephant seal has no tags and I have been calling her circle sister because of the circular marks on her back. As you can see her moult is almost complete and the circles are  at least a little visible on the new coat so I will still be able to identify her as an individual.

This is the back left side of the newly moulted "circle sister", still identifiable by the small circular scars.

By mid-morning, the light southwesterly winds left over from yesterday’s blow had wandered over to south and they stayed southerly until early evening when they turned back to west. The barometer continued the slow ascent begun early yesterday, throughout the day. Although there was a mix of sun and clouds today, light levels were high and reached over 1000 W/m2 at the peak. Forecasters are calling for strong westerly winds again, with a chance of showers Thursday.

Four Whale Watching vessels were noted in the Ecological Reserve today, visiting on return from the west, heading towards Victoria. No sports fishing vessels were noted in the ER.

The Canadian Coast Guard Helicopter (Fisheries and Oceans) dropped by today to service the light, which went dark the night before last. Dave (pilot) and Derek (technician) were a welcome sight in their lovely little Messerschmidt, which was carefully put down at the base of the light tower stairs.

Ten of the elephant seals managed to go through the measuring device today while I was sitting, waiting for them with the camera. I also spotted tags on the young female Northern Elephant Seal with serious skin issues. I may have mentioned her in a previous blog, I called her psoriasis sister last fall and Courtney named her crankypants in spring 2014. She is very vocal and easily disturbed by the other seals. She is usually off by herself but today she was caught in a traffic jam for daily ablutions, which really seemed to upset her. I have observed her many times last fall and this spring but never noticed the tags before. She moves as if in pain, complains loudly and leaves a trail of blood. She has many open wounds that look like holes and cracks. The right tag is number A114 and although it is difficult to read the left side, it is perhaps A476. She has all four tags still.

 

Crankypants has a tag number now A114.

A branded Steller’s Sealion # 411R was noted today. She looks big for a female but that is what the record says, branded as a pup in July, 2005 at Rogue Reef, which is in the very southern end of Oregon. I will check with Pat Gearin on this identification.

There were no visitors other than the Coast Guard crew and maintenance chores were all routine.

Fine Day in Spite of the Forecast.

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.

A Changeable Spring Day.

During the early part of the morning, the flag hung vertically, stuck to the flagpole, wetted by fresh rain. Later in the morning, when it occasionally fluttered, it was from almost imperceptible, easterly zephyrs. After lunch it blew north 10-15 knots for a while before switching over to the afternoon westerlies mid afternoon. Although there was significant rain (see figure below) throughout the day, there was also lots of sunlight and we surpassed yesterday’s level by over 30%. The barometer started rising in the early morning and by 17:30 was at 1008 hPa. The forecast for Saturday is for a continuation of the afternoon westerly pattern.

Only one whale watching boat was observed in the Ecological Reserve, just at dusk, although several headed west and back through Race Channel. One sports fishing boat fished very close to the boundary at Rosedale, but clearly outside. The Life Saving vessel ‘Spirit of Sooke V’ came through middle Channel this afternoon at a very stately pace and then swung around and went in between South and Great Islands and returned to the west.

A pod of at least four Killer Whales passed to the south of Race Rocks, heading west at ~07:00. It was not possible to determine which population and there were probably quite a few more than four. They were quite spread out and moving fairly fast, travelling about half way out to the US/Canada border (yellow can buoy) from Race Rocks. A flock of 23 Black Brandt flew through Middle Channel about the same time, also heading west. The Barn Swallows appear to be staying on the island somewhere; at least they were here bright and early. This place is certainly a haven for an insectivore. I hope they stay.

Right now they are in their alternate, or breeding plumage, otherwise in the winter their colouring is more like a winter murre or murrelet with lots of white, gray and dark gray.

The Pigeon Guillemots are spending more time on land as spring progreses. These true seabirds are ill equipped for walking with their feet used as rudders for underwater flight, and set far back on their muscular little bodies. I don’t think they are actually nesting yet but certainly getting use to land. Their favorite roosting spots are in the surge channel between the energy building and the science house, on the jetty and its’ upland scree and cliff area and on the little cliffs just southeast of the light-tower.

Now that the winds have settled down, the eagles are back and making determined attempts on the Canada geese. They also spend a considerable time on the pinniped haul-out rocks.

I keep expecting the Harlequin Ducks to leave and head for the mountains, where they nest and lead their summer  lives. There are at least four here still and probably more.

Harlequin Ducks are also supreme under-water swimmers and specialize in white water: in rushing  mountain rivers and streams in breeding season and in the sea the rest of the time.

A new (to me), young, female Northern Elephant Seal joined the Great Race elephant seal group today bringing the total to nine, five males and four females. #5850, the three year old male, embraced the new female (literally) and although he is the smallest of the males on the island, while the other males were practicing their jousting he had his ‘pinky’ out and was snuggling up to the new arrival. It is the first time I have seen seals hold ‘hands’.

A student group is arrived just before dinner and are staying over. They will be part of a first year biology field trip that will be here most of tomorrow. Work was routine today but the day was anything but routine. Amazing place.

Beautiful Spring Day

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

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.

Bald Eagle versus Canada Goose

Today’s weather was a mixed bag. Early on there was thick fog, which thinned by dawn and cleared in the early morning. Then for a short time it was glorious and fairly calm with winds westerly up to 15 knots. The westerly wind doubled in the early afternoon and by 4:00 PM it was gusting well over 35 knots in the tower. On radio watch for the afternoon’s activities, I kept a weather eye on Pearson College sailing vessel Amatuana as she was blown across to Victoria in no time flat. Nicely done.

Only one whale watching boat was noted in the Ecological Reserve today and when I finally spotted them, they were pounding out through wind and tide towards Race Passage. Their sound alerted me to their presence.

The Northern Elephant Seals are starting to moult and data collection on basic biological parameters began today including non-invasive, length measurements using the marine railway as a big meter stick.

 

If only this female were lying next to a big ruler, we would have a complete data set on her for April 17, 2015.

There were 14 visitors first thing this morning. Courtney, driving Second Nature, brought out one of Laura’s first year, marine science classes. It was an early start for these  students but they had breakfast en route and were very efficient on shore. They did a quantitative, community ecology activity on the low tide. They were trying to determine if and how the diversity, abundance and distribution of intertidal macro-biota changed with vertical height. They used water levels to measure vertical height, (an ancient Egyptian leveling technique based on the fact that water will always find its’ own level), transect lines to position sampling and quadrats to focus sampling efforts. These photos of the students, were all taken by Laura Verhegge.

Courtney is a big fan of elephant seals and so she was keen to help with the first elephant seal measurements this morning and assisted in working out a way for one person to measure the elephant seals without disturbing them. As of this afternoon the marine railway is the new ruler and first measurements made of a young male were very close to those made earlier with a laser, measuring device. The laser technique required two people, two long boards, a right angle check and eye safety protocols. The laser technique had potential to bother the animal (if it was awake). The new technique is passive, non-invasive and non-threatening.

I saw a juvenile Bald Eagle attack a goose sitting on her nest today. I had suspected this was going on but good to verify. The eagle might have been successful with back-up, but the gander flew in and together with the goose, drove the eagle off. You can guess who I was cheering for. I know it is not science but there is no hockey out here and I am Canadian, eh.

 

A Stellar Day

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.
