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.

A branded and tagged California Sealion # U 902 was noted hauling out on South Islets this afternoon. Note the large range of sizes of both species.

California Sealion branded and tagged U902 also read as C902 C is for the mouth of he Columbia River where it was born.

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.

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.

The Northern Elephant Seals continue to grace Great Race and I am getting used to them not reacting at all to my presence on the walkways.

The Glaucous-winged gulls are starting to mate and gather nesting materials. The Canada Geese are busy defending territory and brooding eggs. Black Oystercatchers are likewise busy when not foraging in the intertidal where limpets seem to be their favourite food.

There were no visitors today and maintenance chores were routine including running the fire pump to fill cistern.

 

Mount Baker to Bahokas Peak.

It was clear here early and once easterly outflow breezes cleared the American side, it was a beautiful day on the Strait. There was a hazy view all the way to Mt. Baker in the east and out to Bahokas Peak in the west. The barometer is continuing its leisurely dive, started Thursday and as the sunsets, is close to 1003 hPa. The forecast is for more of the same with showers and a chance of thunderstorms.

No tour boats or fishers were noted in the Ecological Reserve today however one boat sped through Middle Channel from the west and then after slowing down went between the South Islands and extremely close to seals and sea lions. Sea lions and seals were on high alert. All of the seals went into the water and some of the sea lions jumped in between the rock and the boat. The boat went back and forth very close to the sea lions several times before speeding off in the direction of Victoria. The whole thing only took a few minutes. The rest of the day made up for it in calm and peacefulness.

Last night as I was saying goodnight to the students who had been helping with chores, there was a definite smell of baleen whale breath in the evening air. I thought it might be the first Humpback Whale of the season. We looked but it was almost dusk and we didn’t see a whale. I heard on the VHF radio today that the whale watching boats had spotted their first Minke Whale of the season, so my guess is that there was a stinky Minke upwind last night.

While doing the seawater sample today, I noticed that there is plenty of big plankton right now. Visible from the jetty are gazillions of beautiful ctenophores or comb jellies. Their scientific name is Pleurobrachia and another common name is sea gooseberry. These jellies are spherical and unlike most jellies they don’t have stinging cells, just sticky cells on their two dangling tentacles, to tangle their prey. They also have eight rows of amazing, tiny paddle-like structures called combs or ctenes. The combs basically do the wave and when they do, it makes a rainbow-like shimmering. So a clear ball, with eight rows of rainbow inducing pulsations and two trailing tentacles; this is a pretty intriguing looking creature.

Ctenophores are important top-down regulators of copepod abundance so they are important ecologically. Copepods are little crustaceans that feed directly on phytoplankton, the photosynthetic kind of plankton. The copepods can be so abundant that at times most of the phytoplankton biomass can be found in their guts. One reason the water is so clear right now may be due to an abundance of copepods. There are also lots of cross-jellies, which are true jellies or cnidarians, meaning they can sting. Their scientific name is Mitrocoma cellularia and they are also predators on smaller animal plankton like copepods. These large plankters are of course also food for baleen whales.

I had a bit of a catch-up day today. I gave the solar panels a thorough scrub and wash, fixed the underwater camera, took photos, cleaned up in front of the boat-house and generally monitored and documented things while tidying up.

It has been a treat to have students out for the weekend and I think they have been enjoying the peacefulness, nature and each other’s company. I went out to dinner for the first time on the island and we had a delicious meal prepared by the students.

 

April 4th – Full Moon and Blood Moon

The weather was much more subdued today with light winds and a morning switch in direction to the east, northeast and then back to westerlies at sunset. The sky was partially overcast but more sunny than cloudy with only the slightest of showers. The barometer continued its very slow and not very steady, decline that began on Thursday. The forecast is for more of the same. Today’s full moon was in total eclipse early this morning and although I was up at 5:00 AM, I did not see it, maybe that is because it was totally eclipsed ; – )?

Only two tour boats were noted within the Ecological Reserve today and they both kept their speed down and seemed to be very respectful of the wildlife. There was no fishing activity noted inside the Conservation Area.  A couple of Kayakers were paddling in the Ecological Reserve today and they were very close to the sea lions. They managed to make it past them without any disturbance, but the sea lions woke up after the kayakers passed. They were only concerned enough to do some neck craning and alert behaviour before falling back asleep.

Ecologically things were very much like the previous two days, the gulls are slowly becoming a little more territorial and parental looking. I saw two holding nesting material in their bills today and several pairs were doing a synchronous bill down dance that might demonstrate to the other how beautifully they will be able to regurgitate into any chicks they might produce together. I also witnessed some nasty bill holding that drew blood and descended into an outright wrestling match. I was not sure if these gulls were territorial competitors or mates but they were determined to not let go of each other. Gulls are supposed to mate for life so it makes me wonder, when I see the same gulls sitting poignantly all alone, on their spots, day after day. Is their mate missing in action or just late?

The Canada Geese are very broody and in some places are running the gulls off. Some geese are already incubating four to eight eggs per clutch.  I guess the crows know this and there is often a small murder of crows strutting around the nesting areas and also being chased off by the geese.

The Bald Eagles are here all day everyday right now and I watched one adult chase off another so there must be something good to eat. Is it gulls? The chase was quite spectacular with climbs and dives and at one point, upside-down flying in self defence. The defeated intruder headed over to Bentick Island.

It wasn’t sunny enough today to just go with solar power and I had to run the generator for a couple of hours in spite of having no extra draw on energy. I know the day is coming when there will be enough sunshine to go through a whole day, entirely on solar power.

Thirteen visitors came to the island today. Chris brought out a group of eight students and his son accompanied him with a school friend. Alex was deckhand again and brought his father who was visiting, along for the brief version of the Race Rocks tour. Alex’s Dad likes using the Race Rocks video cameras, so one more reason that I need to figure out how to get cameras #2 and #5, back up and running. The students will go back mid-day on Monday and are already earning their keep.

Chores were a mix of entropy fighting of  today. It was really nice to know that there is lots of water in the midst of churning compost and the usual tasks. I am still tidying up wood and very grateful to Alex and Virginie for all the firewood and lovely kindling. I also want to thank Nick for leaving the house so spick and span, very nice.

Back on the Rock

Last night’s storm blew in just as shift-change finished. Nick Townley waved goodbye from Second Nature as Chris Blondeau, still in his dry-suit from the diving activity, pulled the vessel out into the tidal stream and headed her back to Pedder Bay.

Six students from Pearson College came out to the rock for the weekend and I started my shift with great company. Their goal was to catch up on studies (and sleep (my guess)) and to have their own experience in this gem of a biodiversity hotspot.

As we unpacked and settled into the two houses, heavy rain followed the black horizon moving in quickly from western Strait of Juan de Fuca. It was very nice to be snug inside as it was a wild night with heavy squalls. There were quite a few rattles and thumps that I didn’t recognize from last fall’s storms. Morning broke with gusts over 30 knots in the tower and alternate clearing skies and rainbows shone through and faded out on all sides. It was a white water scene with wind and current colliding in a frenzy. The barometer which had taken a nose dive Thursday and Friday, climbed back up to over 1024 HPa from Friday’s low of 1009. By noon, the westerly winds had dropped to 12 knots and the afternoon and evening was uneventful; overcast with showers and light winds shifting to northwest.

Although there was no fishing activity in the Ecological Reserve (ER) today, five wildlife viewing tour boats were noted. I was surprised by the number of both Northern and California sealions still hanging out and there were at least 75 Harbour Seals hauled out in the afternoon (not a complete count. I saw two pairs of adult bald eagles and numerous other birds including Canada Geese, Black Oystercatchers, Harlequin Ducks, Black Turnstones, Pigeon Guillemots, Double-crested and Pelagic Cormorants and an interesting mix of gulls. Many of the Glaucous-winged Gulls are already paired up and getting excited about spring. They are scattered around Great Race in all the places that there were nests last year. A much more condensed flock of gulls with about 100 birds was hunkered down in the lee of the rock on the west side of the science house. This flock was a mix of some unexpected visitors including Herring Gulls, Ring-Billed Gulls and even a few California Gulls, probably en route somewhere else. As dusk fell last night I heard the calls of Killdeer and it really felt like my home away from home.

It was great to get back up the tower again and have a good look around and for fun and more exercise, I started clearing off some of the winter’s woody debris accumulated on the marine railway. Greenlanders Hana and Malou joined in and we made it into a bit of a game, practicing our aim and strengthening arms. When we finished there was a stream of wood heading out to sea and we hoped that the whale watching boats were avoiding the busy tide lines.

Atmospheric pressure rose from around 1004 hPa yesterday to top out around 1020 hPa near Saturday night. Pressure has been falling today; winds up to 45 knots expected Tuesday.

Most of the sealions are out on the south islands now.  There are still a few on the main island, bellow the fog horn and the engine room.

Boats in the reserve: 2 dive boats, 1 whale watching boat, and 1 sailboat under motor.

Moved fire wood, cleared boat ramp and took down more electric fence.

 

Weekly Census of Race Rock’s Megafauna

The wind blew about 10 knots from the north.  The barometer rose overnight from 1009 hPa to 1013 hPa as the sun set at 16:29, beginning to drop in the evening.  The sea was rippled.  The sky was mostly overcast with some breaks of sun and occasional light rain showers.  It hasn’t rained here during the day (possibly at all) in about two weeks.

There was one whale watching boat seen in the reserve today.  It spent a lot of time near the southern side Race Rocks, where the whale watching boats don’t usually go. Three small grey inflatable military boats sped around the edge of the reserve at 15:00, coming within less than a hundred meters of the islands.  After their circuit, they headed back towards the navy base.

Here are the results of the weekly census:

Steller Sea Lion: 263
California Sea Lion: 208
Harbour Seal: 7
Northern Elephant Seal: 5
Bald Eagle: 4 (2 adults, 2 juveniles)
Canada Goose: 9
Harlequin Duck: 3
Double Crested Cormorant: 44
Pelagic Cormorant: 147
Black Oystercatcher: 10
Gull: 396
Black Turnstone: 20
Rock Sandpiper: 3
Surfbird: 17
Fox Sparrow: 1

As always, there were variations in the numbers seen since last week.  There were fewer harbour seals.  I checked them throughout the day, the most I was able to see at one time were seven, scattered around the many small islands.  The tide was fairly high during the daylight hours, which tends to not be good hauling out conditions for the seals.  There were more smaller birds seen this week.  It was easier to spot smaller birds this week because of the lower wind speed.  I had a tough time distinguishing the rock sandpipers amongst the surfbirds.  While they look very similar, the surfbirds are a bit larger and have shorter bills.  See if you can tell the difference in the photos below.

Shift Change

The wind was blowing northeast this morning 20 – 25 knots, it dropped mid-afternoon for about an hour and then swung to the west. The west came on strong in the late afternoon and blew over 25 before settling down to 15 -20 knots. The barometer, which has been falling all day, started climbing at 19:00 and the forecast for tomorrow is looking better with light winds forecast.
There were only two whale watching vessels spotted in the Ecological Reserve today. There were no other vessels other than Second Nature dropping off Nick Townley the new eco-guardian and Pearson College student Riikka who is here to finish her project week.
