Shift Change?

The wind blew from the northeast between 17 and 27 knots. At 15:00, the wind died down a bit, blowing between 12 and 14 knots for several hours. The barometer dropped from 1014 hPa to 1008 hPa. The sky was clear, with some clouds in the south. Whitecaps rolled in from the northeast, calming down in the early afternoon. The temperature reached a high of 6.7oC at 15:00.

There was one whale watching boat seen in the reserve.

The winds, swell and tides combined to allow me to stay another day on the Rock. Between my time mopping the floors and tidying up inside the buildings, I observed sea lions through the binoculars. There were no branded or entangled sea lions observed. They all appear healthy. Many have moved on from Race Rocks, probably to go further up the west coast of Vancouver Island.  It will be interesting to see how many are still here. We will have to wait until tomorrow’s census to find out.

The Sun is Shining

There was a light breeze today, not getting higher than 5 knots. The barometer rose throughout the day. The clouds parted mid morning to produce a gloriously sunny rest of the day. The high this afternoon was 13.2 C.

Before Anne finished off her shift, she showed me how to perform a few more maintenance tasks: operate the boat winch, run the washing machine with rainwater, test water salinity and measure the fuel levels in the tanks.

Anne spotted a new tag on an elephant seal. The elephant seal that she mentioned in Wednesday’s log with the tag 7625, has a tag on his other flipper with the number 7688.

One recreational fishing boat passed by the jetty this morning. There were two whale watching boats noticed going through the reserve this afternoon.

There were at least two flashes of lightning seen in the west and loud claps of thunder at 19:00.

Trip to RR to Plan for neck-ringed sealion treatment

Today Chris Blondeau,. and Courtney Edwards  took Martin Haulena , and Joe Gaydos to Race Rocks to meet with Ecoguardian Anne Stewart and take stock of the facility and make plans for how to deal with the plastic neck bands  that we have are observing with the onset of the large numbers of sealions each year.

Martin is the Head Veterinarian at the Vancouver Aquarium, Joe is with Sea Doc Society in the San Juans and with U.C. Davis , California.

Whistling House

There was a big blow last night and I learned that this house can whistle; with three distinct tones, synchronously, very musical. This morning there was a swell from the southeaster and an even bigger groundswell coming in from open sea to the west. Add the tidal race to the mix and you can imagine that the wave patterns created were mesmerizing.

It seemed like the day was in recovery from the storm, with gentle winds from the north-northeast, light rain and overcast. The pattern of barometric pressure change was not so reassuring, falling since noon it is now back below 998 hPa. That is where it was for last night’s big blow. It looks like the forecast is for more of the same.

There were six whale-watching boats observed in the Ecological Reserve today; five Canadian and the almost daily visitor from Port Angeles, called Island Explorer. The big draw, other than Race Rocks itself, were abundant Humpback Whales in the area. It certainly wasn’t the weather. At least two of the Humpback Whales were in the Ecological Reserve .

There were four Elephant Seals on the marine railway today, Gat (#5850-6967) , Flake and two larger animals. They ‘played’ together and then slept together for most of the day. More sealions than have hauled out since about a week ago, were also sleeping soundly throughout the day today, perhaps recovering from last night.

The three entangled Stellers sealions that are proposed candidates for disentanglement were all attending, two of them hauling out close to the living-room window of the science house.

When I was doing the seawater sample I noticed a couple of Harlequin Ducks foraging on the north side of the island. I would like to see them on the underwater camera.

More shorebirds were observed foraging on the abandoned sealion haul-out today; Dunlin, Western Sandpipers and Sanderlings were foraging with the Black Turnstones. The smaller birds were kneading the substrate with their feet and probing. That area is completely covered in a mat of sealion hair from their moult.

Even though it was a dark and gloomy day, the solar panels managed to keep up with operational, electrical use. The generator is just cooling now after topping up the batteries for the night.

Musical Rocks at the Race

It was another north-easterly day, with an ocean swell running up and down the islets of the Race. Although it was mostly overcast in the morning, periods of sunshine dominated and it was a pleasant, autumn day. The barometer continued to climb until about noon and then slipped back down, but not as far as yesterday’s low. The marine forecast is for variable winds in the morning and west Wednesday evening with periods of rain during the day.

In the pinniped world of Race Rocks, haul-outs are shifting around like musical chairs. Steller Sea lions are now abundant on North Rock, which in September was the exclusive domain of Harbour Seals. There is a small Harbour Seal hauling out in the jetty bay now and most of the California Sea Lions have moved to the south and west side of Great Race. Middle Rock, which had ten Elephant Seals, a few weeks ago, now has over one hundred Steller Sea Lions and five of the Elephant Seals have moved back onto Great Race. They arrived all wet and big-eyed this morning and moved in for all day slumbering. All of these pinnipeds make interesting sounds, music to their ears, I am sure, and they all distinctly different. More on that another day.

It is quite delightful what you can see out your kitchen window here. I looked out while doing dishes this evening and saw two large Humpback Whales to the south, just outside the Ecological Reserve near Rosedale Reef. There were no boats around, just the two of them blowing and diving, circling around in the same area, taking fairly short dives and showing their big flukes in a beautiful display of might and grace. The dishes were quickly superseded with the spotting scope and binoculars. A sport fishing boat approached, slowed and stopped a respectful distance away and just sat there taking it all in, for a long time. When they left the scene, they did so slowly, giving the whales a wide berth. I believe that this sort of respect insures a better viewing experience as well as protecting the whales. Earlier in the day, I stopped for tea and was just heading for my book when I looked out the kitchen window and saw this plain, medium-sized shorebird foraging with the Canada Geese. It was a Dunlin in winter plumage.

Routine maintenance was augmented with getting the Underwater Video Camera (Camera #2 on this web-site) hooked up to the Internet and starting winter preparations such as getting the furnace running. I had hoped to join the marine science class by boat for their kelp forest adventure but the swell and wind waves were a bit too large to launch and retrieve the boat.

Thanksgiving Edition (No Turkeys Here.)

The day started with a hazy, overcast sky and an ocean swell rolling in from the open Pacific. Although visibility was 10 to 15 nautical miles, the marine air gave everything a soft, muted look and both Port Angeles and Victoria looked further away than they actually are. In the morning, winds were light to gentle breezes starting in the southwest and swinging over to southeast. In the afternoon it shifted to north-northeast and became noticeably colder and wetter.
The ocean swell became dramatic by mid-afternoon, exploding over north rock and making a rolling break into the jetty bay, surging right over the jetty. Although the barometer was higher today than it has been all week, it is now slowly dropping and Monday ‘s forecast is for more clouds, wind and rain. Hmmm sounds like October.

Whale watching activity was fairly brisk today with seven boats in the Ecological Reserve. Everyone was fairly well behaved. Seaking Adventures was certainly giving a lot of throttle in the Reserve, crossing from Great Race over to North Rock but that may have been because he was bucking the tide. There were also a couple of sports-fishing boats passing through the Reserve in a hurry, Foghorn Charters was one of those two.

Some operators may not know that the speed limit is only 7 knots within the Reserve.

A large Humpback Whale passed through the Reserve westbound, late afternoon, there were no whale watching boats around.

A lot more gulls arrived with the cool wet weather and are roosting just about everywhere on Great Race now. I am curious what the numbers will be for this week’s census on Wednesday.

Western Gulls are a little north of their usual range here and hard to distinguish from Glaucous-winged X Western Gull hybrids.

With the influx of California Gulls it is going to be tricky distinguishing and counting all the large gulls. A gull that is easy to distinguish and also a favorite of mine, is the Heerman’s Gull.

There were two young Elephant Seals on Great Race today and one of them was “tagged as a weiner in 2012” at Ano Nuevo Island in California “and hasn’t been seen since, so this is an important data point” according to Dr. Patrick Robinson, Año Nuevo Island Reserve Director.

Race Rocks has become Canada’s main Elephant Seal colony. It is important as a fall haul-out location for sub-adults, as well as a winter birthing and mating site and spring moulting site.
Race Rocks is an ecological treasure located at a key location next to busy shipping lanes and popular sport-fishing grounds. I am thankful to those who had the vision to protect this amazing area and thankful to be able to experience it.

Fogimatrix.

The weather here was dominated by fog today. It lifted in an interesting way this morning so that you could see out and under the fog for several miles yet there was thick fog above, at very low elevation. The rising sun shone through this clear layer, creating a weird and wonderful lighting effect from below. By mid-day the fog had burned off and sunshine prevailed at sea level. There was still fog in the shipping lane and the tops of the Olympic mountains were visible. The fog flowed back in by mid-afternoon and thickened steadily after that, pushed in by a westerly fog wind. During the day there wasn’t much wind until late afternoon/early evening when it picked up to 15 to 20 knots from the west. The barometer continued its slow trend downward that started a few days ago and the forecast looks relatively good until rain on Friday.

There was a fairly steady parade of whale watching boats in the Ecological Reserve today. They were looking at Humpback Whales, Harbour Porpoise and of course the Sea Lions. Sixteen tour boats were noted although I may have missed some in the fog. One of the tour operators had the chance to see a really big (tyee) spring salmon swimming through the kelp forest.

There were sports fishers catching Coho, Spring and Chum Salmon to the south and west of Race Rocks and many sea lions were also busy catching salmon while at the same time helping to feed the gulls with their scraps, not out of any benevolence, just because they are messy eaters.

There are many gulls here now including Glaucous-winged, Glaucous-winged hybrids and Thayer’s gull which are challenging to distinguish. I look forward to doing the census first thing tomorrow to try and figure out how many of which species. The Heerman’s Gulls continue to benefit from sea lion salmon treats which they certainly can’t do where they breed in Mexico. I like watching them. They are very beautiful and have a interesting feeding behaviours that they may have learned from birds like skimmers where they live rest of the year. They fly with their lower bill hanging down just above the water and occasional skim the water with it, catching small prey.
There are many sea lions on the west side of the island now and the westerly wind carries the dusty grime from them onto everything in its path. The Savannah Sparrows feed in and around the sea lions.

These little Savannah Sparrows forage through the sea lion waste picking up morsels and probably a few parasites.

Elephant Seals have been hauling out on Middle Rock for over a month and now some are back on Great Race again. There was a small one hauled out on the northeastern side and a bigger one on the railway with the sea lions.

Washing the solar panels took a long time this morning. They were really dirty. I will do them after the census and it will probably take even longer, tomorrow as I want to shovel off the organic stuff that has accumulated before the electrician arrives to work on the panels. Today I readjusted to life on Race Rocks, finished the month-end report for September, did the seawater sample, made freshwater with the desalinator, ran the Lister generator and sorted photos as well as sea lion brand and entanglement data.

This entangled California Sea Lion has been spotted repeatedly since the end of August.

Marine Science Students Visit Race Rocks

Coming from Bamfield, I expect large volumes of water when the barometer drops and it starts to blow southeast. It was grey and wet today but the wheelbarrow I left out to collect rainwater only has about 500ml of water in it at the end of the day. The barometer is still sliding so maybe I should be careful what I say. The wind did turn around to westerly for a while as it cleared in the late afternoon and is now flowing out from the northeast with more drizzle approaching real rain. From Environment Canada’s forecast it looks like the trend for this week.

Although there are still plenty of recreational fishers around, only one was noted in the reserve today and they were looking at sea lions. There was only one whale watching boat noted in the reserve.

Laura brought the first of her three marine science classes, from Pearson College to Race Rocks today. Courtney masterfully landed Second Nature at the very unforgiving pier and we had a wonderful field trip with a student:teacher ratio of 4:1. The students were really good at moving with stealth so as to not startle the sea lions. This allowed for good sea lion observations, which were noted in their journals. They saw all four species of Pinnipeds and added to their growing species lists with Black Oystercatchers, Black Turnstones, Glaucous-winged, Heerman’s and Thayer’s Gulls. They spotted new (to me) branded California Sea Lions including three branded in the Channel Islands. All of the students had a bird’s eye view from the top of the light-tower thanks to Courtney and we finished off with warm cinnamon buns at the keeper’s house.

After the visitors left, I caught a glimpse of these two Steller’s Sea Lions entangled in sports fishing gear. Those are salmon flashers hanging out of their mouths, which is not good news, as these cannot be disentangled the way the neck-rings can. The individual with one flasher has been hauling out at this same spot for a few weeks now. The one with two flashers, has not seen before today.

I will be watching out for  this animal over the next month.

Today was the first time this animal with two flashes was seen here. It will be easy to distinguish it from the one with only one flasher.

Last Blast of Summer

Tomorrow is the equinox and it was a glorious last day of summer today on Race Rocks. In the morning, outflow northeasterly winds soon gave way to westerlies, which gained momentum creating whitecaps and active seas in the afternoon. Both yesterday and today there was also an ocean swell, indicating a storm out at sea. Some of the surges created large, standing waves in the tidal flows. The barometer continued slide today and a change is on the way with showers forecast to start by tomorrow evening.

There were only a few whale-watching boats today, four observed in total. The Ogden Point Dive Centre’s charter boat ran a dive right off the jetty today. A few recreational boats stopped to watch the sea lions and three were speeding in the reserve, as they came into and left the area. A Pedder Bay, Oak Bay Marine Group rental boat didn’t bother to slow at all and sped through the area packed with sea lions.

After picking up calipers at the floating lab, I was able to almost complete meristic data collection for the Glaucous-wing Gull mortality study. Measurements were made of over 50 gulls in order to determine the age range and location at death. It has been so dry for so long, that the birds were basically mummified, not nearly as gross as standing up-wind of the living sea lions.

Several opportunistic brand photos were taken today and census photos were taken to validate against the more traditional census technique.

Sometimes the brands are easier to read with binoculars than in the photo. This one is 1032.

It seems that more Steller’s Sea Lions, Thayer’s Gulls and Double-crested Cormorants are arriving daily As you can see from this photograph of one the main California Sea Lion sleeping areas they are packed in tightly and not strictly segregated by species.

Sea lions pack into sleeping areas. This big Steller's Sea Lion caused a ruckus by walking over the Californians.

The more mundane tasks of washing the solar panels, building up the compost, washing windows and mending the fences were done in the morning and it was actually hot, hmmm, just like summer. The seawater data was collected in the afternoon as the sunshine powered the solar panels which in turn powered the desalinator to make fresh water out of salt water. As the sun set south of Cape Flattery now, the classic Lister generator topped up the batteries for the overnight period.
