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.

Today was the day, for the weekly census of megafauna and these are the results:
Steller’s Sea Lion 176
California Sea Lion 406
Elephant Seal 6
Harbour Seal 168
River Otter 2
Canada Goose 4
Greater White-fronted Goose 4
Double-Crested Cormorant 18
Pelagic Cormorant 8
Cormorant sp. 2
Black Oystercatcher 8
Black Turnstone 11,
Killdeer 2
Surfbird 28
Common Murre 4
Thayer’s Gull 113
Glaucous-winged Gull 22
Heerman’s Gull 6
California Gull 1
Western 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.

Last Blast of Summer

Posted on by

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.

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.

Oriole

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.

Standing Waves

Posted on by

The fine weather continued today with light outflow winds and clear skies. The barometric pressure rose to almost 1020 hPa by mid–morning and then started to slowly slide back down. This pattern is forecast again for tomorrow.

I counted 32 tour boats in the reserve today and may have a missed a few as I was busy. I talked to the Garry Fletcher, Ecological Reserve Guardian and learned a great deal.
There were Biggs Killer Whales out to the west again so many of the boats broke up their trips coming or going with a stop at Race Rocks. A few recreational fishers went through at low speed but no poaching today. The only transgression noted was a Grady White speeding. The man with the white hat and red rubber boat was back but stayed just outside the line.

Just before sunset, an enormous aircraft carrier headed past and on out to sea. Ahead of it was a container ship and behind a schooner. The volume of goods and people coming and going in Juan de Fuca Strait is really amazing and it all passes by Race Rocks. Port Metro Vancouver alone trades $184 billion in goods and then there is Seattle, Victoria, Bellingham, Spokane etc..

Corrections to yesterday’s log: 1. There are still at least two Pigeon Guillemots feeding young. 2. I forgot to count in the four Canada Geese that are here daily. 3. I got a good look at the Black Turnstones from the tower today and counted 23.

I did some research today, starting with reading a few papers on Steller’s and California Sea Lions and looking at a paper on Glaucous-winged Gull chick mortality. I talked to Race Rocks Ecological Reserve Guardian, Garry Fletcher, learning a great deal. I started a Glaucous-winged gull survey today and found 30 so far. It is important to get this done before it starts getting too damp.

The practical side of the day involved more cleaning and starting a perimeter fence for the science house. The doors of the house are no match for a 2200 pound sea lion.
I watched the creation of large, breaking standing waves today, right in front of the house/jetty. The tide was flooding in and there was no wind so there must have been some ebb pushing out against it. Pretty spectacular for a few minutes then it calmed down.

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.

Sediment Filters Installed

What a beautiful, warm, summer day. The early fog to the south and west disappeared and it stayed calm and got warm. The smoke and particulates made for another spectacular sunset, this time without a cloud. The barometer has been slowly rising since last night with a bit of a leveling this afternoon and evening. It looks like they are forecasting outflow winds for tomorrow and that might keep the fog at bay.

There were 17 tour boats today and most of them were very respectful of the seals and sea lions that they were watching in the reserve. The recreational fishing fleet seemed to be off to the west towards Beechy Head and the Bait Shack. Although a few boats passed through slowly, no one was jigging in the reserve today.  Second Nature and Hyaku made several trips out and around the reserve with groups of students rotating through their orientation activities.

There were military explosions during the late morning and early afternoon.

There were only 99 adults Glaucous-winged gulls at sunset and I could only spot three young ones, (still actively begging). The rest have moved on. There is still one demented gull that is trying to nest, bringing bunches of grass and acting agitated. I wonder what happened to its internal clock? I also spotted both Heermann’s Gulls and California Gulls today. The number of cormorants, both Double Crested and Pelagics continue to rise. Every night a mystery bird arrives after dark and calls a bit. I would love to figure out what it is. It almost sounds like a Greater Yellowlegs but it is the wrong kind of habitat. I wonder if it flies out here because it is a safe(ish) place to sleep?

A lot of maintenance work was accomplished today. I started by washing the basement floor where plumber was going to be working. Courtney brought the plumber out in Second Nature in the morning and while he plumbed Courtney and I dealt with propane tanks and electric fences. It was good to be able to chat with this veteran eco-guardian who now works on the waterfront at Pearson College. I learned a lot. Now both houses have big cartridge filters in-line in and it looks like really professional.

 

Thunder and Lightning

It was a dramatic day weather-wise with near-gale westerlies and a heavy downpour that dropped almost one centimetre of much needed rain. Just before the sun went down there were intense rainbows. The barometer continued its slide but a nice sunset and the westerly wind warning, mean sunshine for tomorrow.

With no killer whales in sight, the whale watching boat numbers dropped to three. There were no recreational boaters fishing in the closed Conservation Area today. There were some big blasts from the military site today late morning and early afternoon. They had a vessel standing off to the northwest of the reserve talking to boaters. Although there were no visitors ashore, Second Nature came within a stone’s throw of the jetty and I waved to Courtney and the Pearson College students aboard.

This morning when I got up there were no sea lions on the jetty for the first time so I will continue my territorial patrols. I scanned for brands/tags from the top of the tower again today, and added more to the growing list. Eventually I will put a finders’ curve together to see if I am approaching the asymptote.

I was a bit grossed out to see the GW Gulls and Black Turnstones foraging in the Sea Lion messes this morning. I wonder what their parasite load is mmm? At least one of the sea lions had evidently been eating krill.

All but one of the young gulls are flying now and it was fun to watch them ‘getting a flying lesson’ from the raven this morning. Okay, I know that is way too anthropomorphic. They were all following raven who seemed to be playing the trickster, (maybe hoping they would crash for breakfast). Ravens are so good at doing aerial flips and such but young gulls are still a bit wobbly. There are still two Pigeon Guillemots carrying food to nest sites. they bring a variety of benthic fish: so far I have seen little flatfish, large gunnels a variety of sculpins and maybe a prickleback.

Other than the routine chores, more window cleaning and moving heavy concrete blocks today, I did some trouble-shooting on the computer and deleted over 11,000 items from the trash which sped things up. I started to read the camera manual with camera in hand. Yesterday’s passing Killer Whales inspired me to learn how to use the camera with the big lens.

Fog and sunshine

Posted on by

There was a tiny bit of rain with fog early today and then it switched back to near gale westerlies with heavy fog interspersed with sunshine. It is a beautiful starlight evening and the westerly continues to drop. The barometer held fairly steady today with a slight increase this evening. Environment Canada says that a strong westerly wind warning stays in effect for Sunday with a chance of showers.

There were ten whale watching boats in the Reserve today and they were all well behaved. A dive charter boat with eleven divers aboard came through the reserve but I am not sure where they dove.

Two male kayakers , one in a green kayak and the other in a reddish-brown kayak came through the passage on the south side of Great Race in the early afternoon and caused a sea lion stampede. They then proceeded to fish right in the closed conservation area. There were also two recreational boats fishing in the marine protected area.

A few more sea lion brands were observed today including one seven year-old female Steller’s Sea Lion that was branded as a pup in 2007 at Rogue Reef , near Gold Beach in southern Oregon.

This was my first day to not see Elephant Seals and California Sea Lions have taken over the jetty and marine railway. Some of them are a bit scary looking and do not want to move so that I can do seawater data collection.

Three River Otters were out and about in daylight today. Usually you don’t see them and just guess that they are around in the evening as all the gulls lift off and call. There were two young, very healthy-looking animals with an adult. Maybe that it why there are so many Glaucous-winged gull chick mortalities here? (Just a guess.)

Alex was quite excited to see some of the old lighthouse artifacts including parts of an old Fairbanks-Morris engine. He also pointed out where the old granite light-keepers house had been removed from its attachment to the base of the light tower.

The tasks today were the basic, regular tasks of  cleaning the solar panels, running the generator, launching and bringing the boat back up in order to drop off Alex, repairing the jetty fence (twice) and taking the salinity measurement. Tomorrow is month-end report time.
