Gray on gray.

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.

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.

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.

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.

Real Summer.

When the good weather comes and stays in September, a friend of mine, who is a west coast, hereditary chief says, “well, white man’s summer is over, now we’ll have real summer” and that is what we are having. It continues, with more on the horizon until at least next Thursday.

Phone and Internet were down here last night so I am posting both days’ logs here.
Yesterday there were only four tour boat visits to the reserve observed and two of them were by the same boat at different times, its’ second visit minutes late to see spectacular whale action. No illegal fishing activity was observed. No visitors. Today was more active with lots of Southern Resident Killer Whales in the area – 27 boats. Some may be speeding in the reserve but it is hard to tell where the boundary is without a range finder.

Yesterday was census day and while compiling and organizing, numbers and photos on the computer, there was a sea lion ruckus outside. When your only neighbours are sea lions and they are calling, you look.

The Steller’s were up and alert stretching out their necks and roaring. The California Sea Lions were barking their heads off (not unusual). About one body length off the jetty a huge, adult male, Bigg’s Killer Whale rose, blew and dove. Two other females (?) and a small calf followed and they were in hot pursuit of either a seal or sea lion. They came up in the kelp to the northwest, one of the females spy-hopping at the east end of the kelp bed while the others looped around to the northwest. The chase culminated at North Rocks where the Harbour Seals haul out.

I lost sight of them on the other side of that islet where I assume they ate dinner. Returning to the house after the uproar died down, I was congratulating myself on the stunning photographs I had taken when I realized that the memory card was sitting in the computer.

Something of interest (to me at least) was a tightly packed group of about fifteen large, male Steller’s Sea Lions that swam into the area where the Killer Whales had just been in front of the jetty. They were in tight formation and swam around together like that for quite awhile, at the surface, heads up and agitated. After the Killer Whales had left the area, small groups of California Sea Lions were observed ‘porpoising’. Maybe they were practicing evasive, aerial actions. That would be an evolutionarily, advantageous activity in which to be well versed. A whale watching boat arrived about five minutes after all of the action.

Today, a large adult Humpback Whale was noted, travelling west, passing less than one nautical mile south of the reserve. Travelling in the opposite direction, later in the day was a very large pod of Killer Whales, said to be Southern Residents by the Whale Watching boats talking on the VHF radio.

I shot more brand-marked sea lion photos today and yesterday and looked for different entangled animals resulting in photos of two entangled, ring-necked Steller’s Sea Lions; one with heavy fishing line like halibut gear and the other too far away to tell. These photos will contribute to a study on sea lion entanglement and we are hoping the disentanglement team might be able to visit and help relieve one of these animals of their plastic noose.

Maintenance chores today and yesterday consisted of fixing fences, fixing the internet/phone (with help from Jonathan over the phone), trying to fix the weed-eater, hand scything hay for the compost pile, seawater sampling, window washing, and fixing the weather system.

Standing Waves

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

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.

Steller’s Sea Lions 243 (7 brands noted)
California Sea Lions 334 (7 completed brands noted, 1 incomplete)
Total sea lions both species = 577

Sharp-shinned Hawk 1
Glaucous-winged Gulls 99 (4 chicks still begging)
Heerman’s Gulls 5

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.

The otters appeared in the early evening again, taking at least two gull chicks. The sea lions, both Steller and California, have started making their way onto the main island. The electric fence is set up to deter them from the jetty, the winch pad (and hydraulic pipes) and the main residence.

We’ve had issues with one of the inverters in the generator room this week which have meant limited power, internet and phone access.

There are a large number of gulls because of the California gulls which make a large majority (~550). There seems to be a much lower number of Glaucous-winged gulls this year from last. I notice there are a lot more dead chicks, be it the evening visits from the otters or the bald eagles that visit several times daily. There has been no sight of Chunk since Sunday night. Currently there are two young males, a female, a stubborn seal that refuses to lie on its back. This stubborn seal was bleeding from its mouth pretty badly leaving a small pool of blood on the ramp yesterday evening. This morning there was still blood on its face though it seemed to be a bit better. Because the bleeding was perpetual I assume it is more than a simple abrasion but I cannot see the wound well enough to be sure.
Several blasts have gone off on DND land this morning and yesterday.
Some sea lions have started using the jetty as a resting spot so I started putting up the electric fence.
