Weekly Census of Race Rocks Fauna

The wind was gusting up to 33 knots from ENE overnight.  In the late morning, the wind settled to around 15 knots from the ENE, and has maintained that throughout the afternoon.  The gale warning for the Juan de Fuca Strait was lifted mid morning.  The barometer dropped slightly from 1018 to 1015 hPa, between overnight to the afternoon.

Two whale watching boats were seen in the reserve at 16:00.

There were a few differences noticed while doing today’s census, compared to last week. There were not as many smaller birds seen today.  The elephant seals are not hanging out near the jetty, where they have been for the past few weeks.  They are now a few hundred metres west, on Middle Rocks.  The harbour seals were easier to spot because they were basking in the sun on the many small islands that make up the ecological reserve.

Here are the results of today’s census:
Steller Sea Lion: 430
California Sea Lion: 359
Harbour Seal: 36
Northern Elephant Seal: 6
Canada Goose: 37
Double Crested Cormorant: 12
Pelagic Cormorant: 41
Gull: 756
Black Turnstone: 1
Savannah Sparrow: 1

A Mighty Wind’s a Blowin’ for Census Day

The barometer dropped all last night from 1015 hPa to 1002 hPa this morning, before it began to climb again towards 1008 by the end of the day.   The wind started from the northeast, but then switched to blow strongly from the southwest from mid morning onwards. The gusts reached 47 knots in the evening.

There were two whale watching boats seen in the reserve.

Once the fog lifted, the census was a bit easier to do. Then the wind blew up and most of the birds hunkered down on the leeward side of the island. I wasn’t able to positively identify all of the individual species of gull. Next week, I will strive to get an accurate breakdown of the number of glaucous-winged, thayer’s, california, western and heerman’s. There are a lot fewer gulls compared to last week, only 14% of the 3224 that were on the reserve last Thursday.

See the photos below for some of the noteworthy species and sights seen during today’s census.

Here are the results of the census:

Steller Sea Lion: 211

California Sea Lion: 404

Harbour Seal: 7

Northern Elephant Seal: 11

Bald Eagle: 1

Canada Goose: 24

Double Crested Cormorant: 14

I will add more information when I find out.  [Updated information from Pat Gearin with the NOAA: The Steller was branded as a pup at Rogue Reef, Oregon in July 2011.  It is a male and so far we have 9 resights from this individual, all from BC.  In 2011, he was sighted at Pachena Point once, and in 2012 he was sighted at Carmanah 8 times.]

A branded california sea lion with the brand “U596.” The “U” or “C” depending on which way you look at it, means that the sea lion was captured in the Columbia River Area. It was branded in Astoria, Oregon.  [Updated information from Matthew Tennis: U596 was branded on August 15, 2014 in Astoria. At that time he weighed ~193 kg. He was seen in Astoria for a few days following the branding and again in the middle of October. This is the first resight for this animal outside of Astoria. They have high site fidelity and being a relatively young animal, it is very possible he will be seen at Race Rocks for years to come.]

Autumn Storm

The sunrise this morning was a brilliant band of red, silhouetting Mt Baker and foretelling of the blustery day to come. A true autumn storm arrived, with a north wind sustaining 20 – 25 knots (up the tower), most of the day. Air temperature was a little cooler than the sea surface temperature of 11.3oC today. There was also heavy rain and a falling barometer in front of the low. It is at 987.5 now ~ 5PM and it is still looking for the bottom. The forecast is for more of the same.

I keep expecting the whale watching industry to shut down for the season, but no, even today there were half a dozen visits to the Ecological Reserve. Ocean Magic surprised me as she came out from behind the north-west “hill” and flew past my living room window: definitely travelling at more than 7 knots through the Reserve. As yesterday, there were also open boats, with ruddy faces looking out from under hoods and hats. The temperature this afternoon reached a high of 10.5oC but with all that water falling from the sky and wind pushing it around, it didn’t look that comfortable just sitting in an open vessel.

A dozen Northern Elephant Seals have moved in and today they were lined up like hydrodynamic sausages, in front of the boat shed doors. ‘Gat’ (#5850-6967) is right in the middle of the pile and ‘Flake’ sleeps alone behind the boat-shed. There are at least two females and at least five sub-adult males. Sealions did not haul out on Great Race in the usual numbers today perhaps it was more comfortable on Middle Rock. There were still Humpback Whales just south of Rosedale Reef but most of the birds seemed to be hunkered down on the rocks. The Black Turnstones seem almost giddy with all the freshwater and are busy taking baths in the bigger puddles

Collecting the water sample was a bit wild today: first I had to get by the elephant seals and then the whole jetty was awash with the big waves that were rolling in. Quite exciting and successful. It was also a great day for collecting rainwater, looking on the bright side of the dark. This was the first day out here that I just took it easy. I lit a fire and read a book. Starting to think of home and my own hearth as my stay draws to a close. This is my last week at Race Rocks until spring.

The barometer climbed right out of its 996 hole today and there was glorious sunshine mixed with dark and nasty, west to southwest squalls. Some of the gloomier squalls also brought thunder and lightening. Band after band of bright and dark passed from the southwest. There was also a substantial groundswell. All of the weather drama made for a spectacular sunset.

Six brave whale watching boats were observed in the Ecological Reserve today and the folks in open boats must have had an interesting time during the big, mid-afternoon windstorm with a sudden and sodden downpour. I was out in the middle of it too, standing by, on the end of the jetty, waiting for a landing, but was too rough. It was gusting ~ 25 knots when I left the lighthouse to meet the boat and there were about 300 sealions hauled out in front of the science house.

There were also five adult Brown Pelicans on South Rock in the middle of this tempest’s blast. They can huddle down into a very low aerodynamic, face into the wind, posture and they didn’t get blown away.

The sealions retreated to the water during the deluge and have only now hauled out again en masse, three hours later. Many of the Stellers are in full molt now and some of them are looking quite scruffy. ‘Flake’ is the only Northern Elephant Sea of the ten blocking the jetty this morning that looks like he is still moulting. He may have a skin condition, as it is quite pink and raw looking.

The biggest of this crew is starting to “sprout” the big proboscis for which the adult males are famous. It looked to me like it was quite uncomfortable and kept awaking and thrashing around and garbling. They must feel really heavy on land after being at sea so much of their life.

Whistling House

There was a big blow last night and I learned that this house can whistle; with three distinct tones, synchronously, very musical. This morning there was a swell from the southeaster and an even bigger groundswell coming in from open sea to the west. Add the tidal race to the mix and you can imagine that the wave patterns created were mesmerizing.

It seemed like the day was in recovery from the storm, with gentle winds from the north-northeast, light rain and overcast. The pattern of barometric pressure change was not so reassuring, falling since noon it is now back below 998 hPa. That is where it was for last night’s big blow. It looks like the forecast is for more of the same.

There were six whale-watching boats observed in the Ecological Reserve today; five Canadian and the almost daily visitor from Port Angeles, called Island Explorer. The big draw, other than Race Rocks itself, were abundant Humpback Whales in the area. It certainly wasn’t the weather. At least two of the Humpback Whales were in the Ecological Reserve .

There were four Elephant Seals on the marine railway today, Gat (#5850-6967) , Flake and two larger animals. They ‘played’ together and then slept together for most of the day. More sealions than have hauled out since about a week ago, were also sleeping soundly throughout the day today, perhaps recovering from last night.

The three entangled Stellers sealions that are proposed candidates for disentanglement were all attending, two of them hauling out close to the living-room window of the science house.

When I was doing the seawater sample I noticed a couple of Harlequin Ducks foraging on the north side of the island. I would like to see them on the underwater camera.

Hadu M & F

More shorebirds were observed foraging on the abandoned sealion haul-out today; Dunlin, Western Sandpipers and Sanderlings were foraging with the Black Turnstones. The smaller birds were kneading the substrate with their feet and probing. That area is completely covered in a mat of sealion hair from their moult.

Even though it was a dark and gloomy day, the solar panels managed to keep up with operational, electrical use. The generator is just cooling now after topping up the batteries for the night.

The Tie That Binds

It was another northeast day, with really not much happening weather wise. It blew NE about ten knots, was mostly overcast in the morning, with some sun in the afternoon. The barometer rose gradually all morning and then started to slowly slide after noon. It is expected that tomorrow’s southeast will bring rain, starting late tonight.

The whale watching boats were busy in the afternoon with Humpback Whales to the southeast of Race Rocks and more activity out to the west. A total of eight tour boats were seen in the Ecological Reserve.

Today was mega-fauna census day and these are the results:
Steller Sealion 298
California Sealion 508

Subi & Bltu
The census was challenging due to the numbers and species of gulls and the fact that both Steller Sealion and Harbour Seal numbers were lower than expected during the morning count, so they were re-counted in the early evening. I generally like to count Harbour Seals on the morning low tide but the tide wasn’t really doing much today. The evening counts were higher for both the Steller and the Harbour Seals. Two new Elephant Seals arrived today. They are both moulting, the smaller one hung out with the dual tagged three year-old, which appears to be staying on. The bigger animals may have gone back to Middle Rock as there were still six animals visible there.

Ring-necked animals as well as tagged and branded animals were also re-surveyed today. I am still working on the branding data from a month ago. Two of the ring-necked Steller Sealions that have been observed since August are still here and languishing as the plastic straps cut into the backs of their necks. I am putting out an appeal to the disentanglement crew again.

The second ring-necked animal ‘highlighted’ here is also branded on its’ left side 946R. I believe that it was branded at its’ natal colony which from the R should be Rogue Reef in southern Oregon. From the number it was branded after 2009 but I will find out more.

If it is not lying on its' left side this ring-necked Steller's Sealion is easy to tell apart from the others.

Did not do much maintenance today other than the basic cleaning, making water with the desalinator and electricity with the generator.

Pea Soup

It was socked in with fog as thick as pea soup today. It cleared off this evening just before six and well in time for a fantastic sunset and my realization that it was probably a beautiful day, just about everywhere else in the region.

There was not much wind today, the high was 5 knots out of the east-northeast and everything is damp almost as if it had rained. Most of the day the flag hung limp and a bit sodden. The barometer continued yesterday’s gradual rise until about noon when it started to slowly decline, ending up at about the same place it started. The forecast looks like rain for at least a week but it probably just means showers. I keep forgetting that rain here and rain in Bamfield are just not the same thing.

There were no whale-watching boats observed although one commercial sports fishing boat stopped by to have a look at the sea lions.

Most of the sea lions have moved over to the west side of the island and are hauling out on Middle Island and some of the smaller rocks. They are seem to be spending much more time in the water instead of sleeping on land and salmon kills are visible all over the Ecological Reserve when the visibility is good enough to see.

Thayer’s Gulls are the dominant gull now in terms of numbers and they seem to spend a lot of their day resting and grooming. All the gulls seem to take advantage of the sea lion feeding events as bits of salmon are flying. I double-checked my Thayer’s Gull identification with Dick Cannings and his super-birder son, Russell and they concur that this is a Thayer’s Gull.

My biggest task today was attempting to muck out the roof of the energy building where the solar panels are installed. It reminded me of a stable job I had when I was a kid. I actually used a snow shovel to scoop out the organic crud that had built up under the last of the panels to be raised by the electrician yesterday. The rest of the day’s maintenance-type activities were the regular jobs entailed in living here; making fresh water, topping up the batteries with the generator (even the solar panels had a hard time keeping up in the thick fog), doing the seawater sampling and sweeping a few walkways.

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.

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

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.
