Musical Rocks at the Race

Posted on by

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 The dishes were quickly superseded with the spotting scope and binoculars.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.

Northeast Winds Switching to Westerlies.

Posted on by

Northeast winds predominated from early morning until late afternoon when they switched around to west-southwest. There were only sprinkles of rain, until the switch and once the wind turned, you could see laden clouds scudding across the foothills and pouring in through the Strait. It started raining in earnest, early evening and is blowing 25 knots from the WSW as I write this blog. The barometer bottomed out today at just over 1000 hPa and is now steadily vacillating in that trough.

There were still hardy whale watchers out in spite of the weather and five whale watching boats were noted in the Ecological Reserve during the day. There was a surprising amount of sports fishing activity in the vicinity. Everyone was well behaved in the Reserve.

Steller Sea Lion numbers seem to be on the rise with over 110 individuals hauled out on Middle Rocks with the Elephant Seals and several hundred more on Great Race. Two more of the smaller (two year old) Elephant Seals and a bigger sub-adult scooted up the ramp, under the fence and off to their favourite Great Race haunts. It is surprising how fast they can move doing the wave. Later I watched two of them sparring, in practice for a fighting adulthood.

It is a treat to have the Harlequin Ducks back from their rushing mountain summer streams. They are such thoroughly white-water birds and seem to seek out exciting places to forage.

Other than the regular duties, I spent some time cleaning up the boat today after a wild landing in the northeast waves. There are a couple of improvements that would improve landing safety including auxillary bunks on the trailer. These could act as a tunnel and help centre the boat so that as a wave comes in and lifts the stern, the boat is not pushed off track. More weight would also be good and so would a bailer that is lashed on. Yes it was a good work-out.

Thanksgiving Edition (No Turkeys Here.)

Posted on by

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.

Another avian visitor spotted today was the small to medium sized sandpiper pictured below, I think it is a Western Sandpiper but would like confirmation.

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.

Posted on by

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.

This Elephant Seal is napping with California Sea Lions on the marine railway.

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.

Out of the Fog

Posted on by

I returned to Race Rocks today after attending the Trans-Atlantic workshop on Ocean Literacy and the European Marine Science Educator’s conference last week, in Gothenburg, Sweden. I am refreshed and inspired to finish off my shift at Race Rocks.
It was warm and sunny when Courtney and I left Pearson College in Pedder Bay this morning but as we drove southeast towards Race Rocks, we were soon enveloped in the cool, damp fog. As the sunny peaks of the Olympic Mountains slid out of view, obscured by fog, the dark shape of North Islet emerged and behind it came Great Race and the light-tower, out of the fog. It is great to be back and was just as great for Jeff, who was filling in, to leave.
It was foggy on and off all day with a few periods of sunshine with visibility of over a nautical mile. Throughout the day, the foghorn blew and I could hear ships signaling as they navigated the Strait of Juan de Fuca in the fog. There was no wind for most of the day but it has been consistently blowing about ten knots out of the west for the past several hours and the fog is thickening.
The fog did not deter the whale watching boats as there were Humpback Whales feeding in the area today and the last cruise ship of the season in port. One smaller Humpback was diving and presumably feeding right in the Ecological Reserve diving against the flooding tide. I wonder if they can use the flow to their advantage in feeding more efficiently with less effort? Natural history speculation aside, the count of observed whale watching boats from 11:00 to 19:00 (dusk) was thirteen with some vessels visiting more than once.
The Chum Salmon run started in earnest while I was away and there appears to be fewer sea lions hauled out than there were before. There are many in the water however. Sea lions of both species are very busy eating Chum Salmon with most of the kills I observed, happening right in or at the edge of the tidal flows. They thrash the fish and rip it apart at the surface and swallow large chunks tail last at the surface as well. This source of scraps, of course attracts gulls. Several species of gull were seen in these sea lion driven feeding flocks today; Glaucous-winged, Hermann’s, Thayer’s and Ring-billed Gulls. There were three or four fairly hefty Elephant Seals hanging around the marine railway today. They have such huge eyes and such clean looking pink mouths. Many of the Sea Lions have serious tooth decay and oral disease.

While I was away there were several a visits to the island. The Victoria Natural History Society made it part of their birding trip on September 27, sixteen friends of the Royal BC Museum made a visit October 4th and a family visit was made by by Mike and Carol Slater, one of their daughters and several grand-children. Mike and Carol were the last light-keepers at Race Rocks and the first Eco-Guardians. They survived some epic storms and I am sure they have some great stories to tell. If you are interested in the “contemporary” history of Race Rocks, there is a lot of information on this web-site, including ancient videos, images and even historic weather events.

My main tasks today were to get moved back into the house, to do the seawater sampling, fix the pier fence and run the generator for a few hours in order to top up the batteries. There is new clean oil in the Lister gen-set and new filters etc. thanks to Jeff. The old Lister seems to run better than ever tonight a I finish my last task, posting this blog..

Gray on gray.

Posted on by

It was a bit of a gray day with some thick fog and even a few patches of sunlight, which made fog-bows. This is my made up word for the colourless, rainbow-like arches made by the sun in the fog. Winds were light and swung around out of the north, northeast and over to the east, with the northeast predominating, at about 5 knots. The barometer was fairly steady today and the forecast for tomorrow is for more of the same only more southeast, also with showers.

There were Dall’s Porpoise and Humpback Whales nearby late in the afternoon, which brought a few whale watching boats with a total of nine noted in the Ecological Reserve. The operator of the vessel King Salmon, of Great Pacific Adventures needs to review the regulations for operation in the Ecological Reserve.

The newcomers today were four Greater White-fronted Geese. This species nests in the arctic west of Hudson’s Bay and the western populations winter from here down to Mexico.

Greater White-fronted Geese were resting and recovering here today.

Glaucous-winged Gull 22
Heerman’s Gull 6
California Gull 1

Gull spp. 256 (probably in similar proportions to above, unable to tell due to distance and fogged glass in the tower)

Fence maintenance takes quite a bit of time right now as new sea lions arrive for the winter and learn to stay away from the houses and off the jetty. They would probably prefer to be right here in the kitchen but that is a trade-off with having a guardian here. Fresh-water production and electrical generation continue to be a priority. Today was also the day for month-end report, house cleaning and packing. I am off to Scandinavia to share and learn more about Ocean Literacy. Thanks to all the PC Marine Science students who were willing to share their thoughts with the participants of the gathering at the University of Gothenberg.

Marine Science Students Visit Race Rocks

Posted on by

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.

Wetter, cooler weather arrives.

There were definite autumn overtones to the weather today in spite of the westerly winds, which shifted over to the southwest a few times. First thing this morning a heavy fog came in and soaked everything. At dark there were ominous looking rainclouds to the west but the forecast actually looks like it is improving. After a week of sliding downhill, the barometric pressure actually rose today and that is a really good indicator of an improving trend.

There were only six whale watching boats noted in the reserve today and I couldn’t see any whales (for a change). The few recreational boaters left on the water stayed out of the reserve. The Oriole sailed past through Race Passage today, flying with the wind and tide.

A series of large military explosions rocked the island mid-day.

Two Steller’s Sea Lions with Ring-necks were photographed today as was a Steller’s with a green flasher hanging out of its mouth. One of the ring-necked Steller’s is not yet badly wounded by the plastic strap, the other (see photos) has the strap cutting into the back of its neck but not yet the front. This animal likes to sleep about ten meters from my house and would be a good candidate for disentanglement.

There were no visitors today. Maintenance chores, other than making fresh water and electricity included cleaning in the boat shed, mending both houses’ fences, and keeping the weed-eater going. The weed-eater makes really good compost mulch.

Killer Whales and Sport-fishers to the West

Posted on by

Another glorious day on the rock with good visibility, calm waters and a clear sky. The barometer rose gradually until noon and then dropped slightly. Barely perceptible outflow winds kept the fog out at sea and it looks like a similar forecast for Friday.

There was a lot of activity in the Reserve today with whale watching boats stopping by to see the sea lions en-route, back and forth between Victoria and the two pods of transient (aka Bigg’s) Killer Whales off to the west. The smaller pod had four individuals and passed close to the reserve heading west spending the day between Becher Bay and Beachy Head. A second larger pod was reported from further west near Otter Point by days’ end. A total of 37 tour boats were noted in the reserve and many more passed by at speed outside of the boundaries. They keep constant contact with the whales during the day and pass off to each other, on leaving the area.

A couple of recreational boats spent time in the reserve today, one photographing sea lions for several hours and the other jigging. The conservation area is bounded by the 40 meter contour, and no jigging is allowed. Jigging targets territorial fish such as rockfish and lingcod although you can catch coho that way too. The Conservation Area is enforced by DFO and is there to protect long-lived, territorial fish like rockfish and lingcod, so that their offspring can disperse to other areas with the currents. A Marine Protected area like Race Rocks becomes a source of recruitment of young fish to nearby areas that don’t have protection and this ultimately makes the fishing more sustainable.

It was census day today.
Biggs’ Killer Whales 4
Steller’s Sea Lions 243 (7 brands noted)
California Sea Lions 334 (7 completed brands noted, 1 incomplete)
Total sea lions both species = 577
Harbour Seals 142
Elephant Seal 1 (pup)
Savannah Sparrows 8 (seemed to fly off to the south across the Strait after visiting)
Double-crested Cormorants 11
Pelagic Cormorants 4
Black Turnstones 7
Sandpipers 5
Sharp-shinned Hawk 1
Glaucous-winged Gulls 99 (4 chicks still begging)
Heerman’s Gulls 5
California Gull 1
Black Oystercatchers 7
The Pigeon Guillemots were not spotted today so I assume that the chicks finally fledged and have headed off to sea. I will miss them. It is fun to watch them ride the currents and carry crazy-looking fish to their young.

There were no visitors today, although both Second Nature and Hyaku made multiple trips within a stone’s throw of the jetty, as part of student orientation week.

What’s your number?

It was a day without fog at Race Rocks and as the westerlies continue, some serious clouds can be seen piling up on far horizons. The barometer rose all day, which bodes well for tomorrow but there may be a few needed showers.

It was a busy day on the water with 26 whale watching boats visiting the reserve. From the expressions on the tourists’ faces, they seemed to enjoy watching the sea lions. All the skippers were respectful except for two travelling together who did not heed the go-slow zone.

There were so many recreational fishing boats that I could only keep track of the ones who were in contravention of the DFO Rockfish Conservation Area closure which runs around the reserve at a 40m depth. Many of those fishing inside the boundary were in rental boats but some of the other speed boats were doing what they do best…speeding. The Pedder Bay Marina is really good about talking to folks who rent from them and informing them about the conservation area.

I looked for tagged and branded sea lions again today and can report another nine California Sea Lions and four Stellers’ Sea Lions bringing the total number of branded individuals sighted up to 29. Eventually we will know a bit more about their stories from those numbers they carry. There are also two Stellers with neck rings cutting into their flesh and one with a flasher hanging out of its’ mouth. There are individual Harbour Seals, as well as both species of sea lions with major wounds. Speaking of wounds, there were two new, (to me), very small Elephant Seals on the ramp today, probably young of the year, judging from the size.

A few Pigeon Guillemots are still carrying into fish into the large boulder area by the jetty. The chicks must leave for sea at night as I haven’t seen any on the water and most are probably fledged by now. Each day, there are more Pelagic and Double Crested Cormorants roosting on the southwest side of the island.

The desalinator worked for a couple of hours during the sunshine today, making fresh water thanks to the solar panels.

Month end inventory was conducted today with measurements taken of all the fuel, fresh water, and equipment run times recorded.

My other task was to try and stake out a small territory on the jetty so that I can come and go and do the sampling. The elephant seals are no problem, they just sleep as you pass, or open one eye. Keeping the more belligerent California sea lions off the jetty seems to be a losing battle and has made getting out to the end of the jetty to sample seawater, extra challenging.
