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.

Out of the Fog

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..

Bigg’s Killer Whales Kill in Reserve.

The barometer rose all day and so did the westerly winds, so by the time the tide started to ebb, the opposing forces made spectacular waves. Tonight is the last full moon of the summer and it is in perigee, closest to the Earth, so it appears to be a big one, marking the third of a trilogy of super-moons we have been enjoying. It also means bigger than usual tides, making things seem even more dramatic. It was clear all day, no fog, but there are low clouds sneaking in along the Olympic Mountains and the look of fog out to sea. The westerly is supposed to be a little tamer on Tuesday.

Twenty-one tour boats were noted in the reserve today as well as one dive charter boat. A couple of the whale watchers looked like they were pushing the speed limit in the reserve and pushing the marine mammal viewing regulations outside the reserve. No illegal fishing was observed.

I am adding photos to the sea lion branding/tagging observations and that will make the data much more rigorous. Another entangled, aka ring-necked California Sea Lion was photographed. This time it looked like plastic strapping cutting a deep and infected wound.

Bigg’s Killer Whales visited again today. It appeared that they chased Steller Sea Lions all the way here from at least Albert Head. It was very dramatic here as they wove in and out of the kelp and through the tidal rips and standing waves, going with the tide and at great speed. One exhausted male Steller’s hauled out just as the chase was passing and he looked as though he may have been part of it all. He collapsed in a heap and immediately went to sleep. He was the lucky one. The kill happened in the reserve, just southwest of Great Race. There appeared to be a fairly small baby in the family of whales. The group was purportedly the T-61s (not sure of the source however). I tried to take photos so will report back with verified identification information once that comes in.

I finished some more of the set up to protect the ‘Science House’ today and started to clean out the northwest entrance to the generator room. There is a lot of very satisfying cleaning here, when you sweep you really get results, today it was many, many, generations of Ligia pallasii exoskeletons. Wow it’s a moult room instead of a cloak room.

Fog and sunshine

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.

 

 

California gull

Northwest winds dropping from over 30 knots this morning to 3 knots and them picking back up to 20 knots by early evening. Barometric pressure dropping since mid-morning. Strong wind warning in effect and fog expected for tomorrow.

7 whale watching boats

6 recreational boats

1 personal watercraft (aka Jet ski, Sea-Doo)

Another elephant made its way onto the island yesterday, bringing the total number to 6. In the past week, I have noticed a number of California Gulls (Larus californicus) on the south side of the main island. They are distinguishable from the Glaucous-winged gulls by their black plumage and yellow feet. (Click here to view a photo from the Race Rocks taxonomy page:

https://racerocks.ca/racerock/taxalab2/2010/laruscal/laruscal.htm.) A bald eagle visited today and yesterday. It plucked out a gull chick yesterday but I did not see it make a catch today.

Clear skies. Moderate West in the am, Force 3. Strong West this evening, Force 6.
Barometer rose until 1600, then dropped. The daily West wind cycle continues, light in the am and picking up in the pm.

3 tour boats

The Race Rocks website says that there are typically 6 Oystercatcher nests on Great Race, I have only found two. Tomorrow I will see if I can find more. The Oystercatcher nest next to the jetty no longer has eggs in it. A bird was sitting on the nest yesterday when I showed the nest to my Mom. If I had to guess, I would say that the River otter ate the eggs because it lives under the walkway very close to the nest. I am curious to see if the pair tries another nesting site. I saw two Oystercatchers poking around the rocks on the West side of the jetty so maybe they will try again. There has been a lot of Eagles around lately. Juveniles and adults. My Mom saw one empty the eggs out of a Gull’s nest. Apparently Glaucous winged Gulls can learn to recognize particular people, to a point where they will allow familiar researchers right up to their nests. My new plan is to befriend the Gulls that are nesting next to the tank shed and maybe they will stop flying at my head whenever I walk past.

Birds Cleaning up Afterbirth of the Elephant Seal.

Nothing goes wasted in an ecological system. A few hours after the birth of the baby elephant seal, Thayer’s Gulls, Ravens and Black Turnstones came by to get a bit of rich protein for the placenta.

Shit Happens…

Glaucous-winged-gull

Injured Glaucous-winged-gull near the jetty

Yesterday evening as I went out to collect the water sample I interrupted a couple of harbour seals feeding on a glaucous-winged-gull. Harbour seals feed on fish more commonly although they do sometimes feed on gulls. The seals, upon seeing me, fled leaving the injured gull in the water. It clumsily exited onto shore but was tripping over its dragging wing. I shooed it back to the water in hopes the seals would return. When they did not and I went out a second time to find the gull wandering aimlessly in the rocky intertidal zone. Meanwhile, the seals had returned to the jetty area and were feasting on a fish. In situations like these we have to make a judgement call and the gull seemed to be needlessly suffering. The chance of it being eaten by the seals was very unlikely since they had found other food and an eagle coming to finish the deed was also unlikely because it was late in the evening and their visits are generally midday. It didn’t seem right to let it suffer through the night so I put it out of its misery.

The solar panels within less than 24h of cleaning

The solar panels within less than 24h of cleaning

In other gull news, an ongoing project we’ve been working on is tilting the solar panels. Angling the panels allows more direct sunlight but more substantially, discourages the gulls from using them as resting spots. Gull droppings can have a large effect on energy intake of the solar panels. Sounds unreasonable? Here’s a picture of the panels after just one day since being cleaned.

On another note, more stellar sea lions have accumulated on the southern rocks. The count has reached over 30.

It always surprises me how long it takes for “summer” weather to arrive in BC. Today it is overcast, blowing 30 with driving rain, and 11 degrees (which feels like 7 with the wind chill).  For Race Rocks weather records see this link.

March ended beautifully but early April has been mostly cool and at times misty. The roofers are here today finishing off the Guest House roof, and I continue to putter away cleaning up and reorganizing everything.
