Blog On.

This blog covers three days, September 15, 16 and 17th; Thursday, Friday and Saturday. It will be replaced by a point form log for the rest of the stay.

Weather and Sea Conditions

Thursday was part of the last high pressure system with sunny afternoon westerlies of 10 – 15 knots. Friday was a transition day with heavy fog burning off by early afternoon and accompanied by westerlies of up to 25 knots. By dusk it had clouded over and showers continued overnight and into Saturday morning. This wet weather came with winds from the north. Morning fog patches continued Saturday and by early afternoon the wind switched from 10 – 15 knots north, to 25 -30 knots west partially cleared with sun between showers. The marine forecast for Central Juan de Fuca Strait includes a strong westerly wind warning. The wind is predicted to drop to westerly 10 to 15 early Sunday morning and showers are expected to end near midnight Saturday.

It appears that the Race Rocks Ecological Reserve weather station has not been operating since mid-June, so longer-term context is not possible other than anecdotal information recorded in recent logs.

Vessels in Ecological Reserve

Commercial whale-watching activity inside the Ecological Reserve boundaries is busy, with 20 commercial visits noted on the 16th and 14 visits on the 17th. The guidelines for vessel activity are not being observed by all operators and some of the commercial vessels are as close as 5 meters from the sea lions (and shore). Some very large vessels are going through shallow passages, making erratic turns in the current, travelling against the current and several vessels were seen speeding (> 7 knots within 400 m of Great Race). No other commercial activity was observed. Although several recreational vessels were seen passing through, there was no sports-fishing activity noted within the closed area.

Ecology

Seasonal shifts are apparent with the return of some ‘winter’ species and visits by fall migrants. There are only seven Glaucous-winged Gull chicks left on Great Race Island that are not fully fledged. The smallest, chick has a badly injured left leg. One other still has pinfeathers on its head and the rest are close to flying. There are notably fewer gull chick remains on the island this year perhaps indicating a lower mortality rate. There does not appear to be any data on the number of nests or their productivity this year so it may just reflect lower productivity. The logged death of the old River Otter may be related to the drop in chick carcass numbers.

Glaucous-winged Gulls are still the dominant gull species here on Great Race. California Gulls are abundant in the area but not roosting on Great Race yet. There are large (>1,000 birds), mixed species, feeding flocks adjacent to the Ecological Reserve in Race Passage and in the distance. California Gulls have been seen resting on thick mats of Bull Kelp in Middle Channel.

Black Turnstones and Surfbirds have returned from the Arctic where they nest in the summer. One Ruddy Turnstone was noted today feeding on flies, fuel for a migration that may extend as far south as South America. A single Sanderling was noted both Friday and Saturday and this is another species that nests in the Arctic and is widespread in the ‘winter’. Black Oystercatchers, which are much more site fidel, are roosting near the energy building in the evenings. At least one Kildeer was heard each evening just after dark.

Both Stellers (Northern) and California Sea Lions are moulting this time of year and are hauling out on Great Race, South Seal and South Islands as well as Middle Rocks and Turbine Rock. Photos were taken and processed, of branded, tagged and entangled sea lions.

Northern Elephant Seals are hauling on both Middle and Great Race and a total of six were noted Saturday. No big males. Harbour Seals are abundant and using these haul-out areas; West, Middle, Turbine, North and South Seal Rocks and South Islands.

A single Sea Otter was observed in the kelp just south of North Rocks Saturday morning.

One Humpback Whale was noted feeding near the Ecological Reserve.

Sustainability

Solar panels are maintaining power for the island in spite of intermittent cloud and showers. Without the weather station operational, sunlight levels are not being measured. The diesel generator is run for a couple of hours each evening to top up the batteries for the night.

Visitors

Kyle brought three visitors yesterday, two from Ocean Networks Canada and one from Fisheries, Oceans and the Canadian Coast Guard, for a site visit.

Maintenance and Operations

Regular chores included the 06:15 daily weather report for Pedder Bay Marina, daily solar panel maintenance, walkway cleaning, repairing and electrifying fences. The outside of the fuel barrel (eco-four) house was scrubbed, tops of fuel barrels stored outside were drained of water, and windows in the energy building were washed. The “science” house was inspected, an open window closed in the basement, exterior electrical box was noted broken from wall and conduit open at bottom (photo). Science house furnace was full on and the upstairs temperature was 22.0o C. Thermostat turned down. It was noted that diesel had been spilled in basement. Spill pads on the fuel drum are saturated and there was diesel on the entry bootscrubber/doormat. Looked at derrick dock woodpile and noted creosoted and pressure treated wood in woodpile, probably a health hazard to burn. Inspected chainsaw chain…just needs filing. Took VHF, charger and manual to top of tower to replace the one missing from there. Wheelbarrows were deployed for rainwater catchment. The conductivity meter’s line was marked with yellow electrical tape so that seawater sampling could be done at measured depth. In the energy building an attempt was made to align the indicator lights on the three Xantrax controllers with the holes. Two out of three can now be seen and the middle one can be seen plainly with the lights out. The flashing rate of these lights indicate the controller’s stage of operation and approximate battery voltage which is helpful to knowing how long to run the generator. Weather station troubleshooting will continue tomorrow.

 

Larus glaucescens: Glaucous-winged gull– The Race Rocks taxonomy

gullfeedLarus glaucescens is omnivorous, feeding on carrion, fish, invertebrates, seaweed and food stolen from other birds. One of the main sources of food for Glaucous-winged gull are the softer bodied invertebrates exposed during the low tide time at Race Rocks. It is also typical of their behavior to take their hard shelled food, such as clams, or gastropods and drop them onto rocks to break them open for eating.

This species is the only species of gull that nests on Great Race Rock. From June to September, there could be over 150 nests on the island. The adults also overwinter at Race Rocks, but occasionally disappear from the islands for a few weeks. They start their complicated behaviours aimed at establishing territories and bonding with mates as early as February or March. Their eggs are laid in June and hatching takes place in early July. In the 2002 season, 100 birds fledged successfully, after several years of failed nesting, probably due to fish shortages in the surrounding waters.

In September, the clean looking feathers of the neck and head take on a mottled gray appearance as they undergo an annual moult.


The following pictures were taken by Ecoguardian Christine Ouradou in July of 2016 and appear in logs from that time.

Common Name:  Glaucous-Winged Gull

The Glaucous winged Gull,
In June of 2000, David Mesiha and Satoshi Kimura (PC yr 25) made videos of different aspects of gull behavior while staying on the island. Thus started the archiving of videos for racerocks.com

June 1-16 : Aggression between males is frequent. This takes the form of plucking grass in a standoff and in beak pulling. In this way territories are defined as the nests are being built.

May 1: Breeding in the colony has started and will continue throughout May and June.

This video was taken in early July, 2001, from the north window of the Marine Science centre at Race Rocks. It shows the second day in the life of a sea gull chick. The parents feed the chick a small fish, probably herring or needlefish.
In June, 2016,  Lester Pearson College set up a live camera to follow the development of one of the Glaucous-winged Gull nests with eggs in the Race Rocks Ecological Reserve . Also the camera had infrared night vision.

Check up for the whaler

Weather

West lo southwest light winds under 20 knots have been on  almost all the time since last week. We got some fog and the fog horn running the whole night between Sunday and Monday to a stop at 8:30 in the morning.The rest of the day was sunny with a flat sea…DSC_0191

Ecological

At low tide the water was pretty far discovering an interesting world of rocks covered with fresh algae. We could count only 4 sea lions (Steelers) around and 60 chickens seen from the front window. If we compare with last year we had 110 sea lions and 87 chickens from the front window .What a different situation.Last year the first one on the jetty came on the 23rd.We will see …the usual 4 elephant seals are most of the time sleeping on Main Rock and the babies are growing fast. Not so much drama I guess because they have enough space but the gulls closed to the path are still defensive and this night a new one was born with 2 more coming (the last ones )so it’s going to be even more difficult to go the jetty! No new dead birds.(only 3 to now ) On Sunday we could count more than 16 whale watching vessels  way beyond the green boyd because of a long pod of orcas.DSC_0217DSC_0220

Maintenance

Guy changed the boat pump for a more efficient one.It was 360 GPM and now it’s 750. He left in the fog early on Monday because of an appointment with a Yamaha specialist. At the college they took the whaler off the water and put it on a trailer.We took the zodiac until the trailer is ready. Camera 3 has been stoppedDSC_0194

Other

3 times this week we had a plane above. Watching boats like usual.

 

 

Unusual eye pattern of nesting gull

This morning I noticed a Glaucous-winged gull on a nest up close to Camera 5 on the West side. These pictures show an unusual eye pattern??

 

Busy Week -end for the gulls

Weather

Saturday:Wind:20 knots Westerly breezes stayed almost the whole day,Visibility : over10  miles;Forecast:30 knots in the afternoon,Sky clear to cloudy;Sea state :choppy.

Sunday:Wind : between 17th and 25 knots for the most part of the day and a gust around 30 knots in the evening at 9:00PM. Sky : clear

Ecological

Gull incubation is happening right now. You can see laying female almost everywhere with their protecting mate . I guess more gulls are coming because it looks to me that it was more crowded last year. Only 2 geese this WE: the couple with the incubating female .. More pigeon- guillemots (some mating) and a few Steeler Seals (5)on the rocks closed to the jetty. 10 Elephants Seals at night …the 2 large males and even the bad looking one always in the same spot closed to the solar panels building. Her skin is not so pinkish so her condition has maybe improved.

 

Boats

Saturday:A few whale watching boats today . The usual  cruising boats going out in the sunset.

Sunday:Early in the morning a tug hauling a big barge with a mechanical pele on, going towards Sooke ,Vancouver Island side. Many many whale watching vessels:5 at a time around noon and even one of them came back 5 times in the same day.

Maintenance

Chainsaw:filling up and sharpening. Some wood shopping for the reserve.Cleaning of the jetty (with the sea water pump and hose :a lot of fun !)soiled by the Sea lions living there almost all the time . They even get so much used to us that it’s difficult to make them dive when we have to get fresh water for the sampling . Solar Panels

Other

Plane heard maybe not above the Rocks but not far .

Ecological

  • Maya and Tazi conducted 4 intertidal transects today.
  • Studying an intertidal transect involves measuring out a certain distance from a peg, and then documenting the different species found every 0.5 metre.
  • In some transects the 0.5 metres are measured by water elevation; in others simply by distance.
  • By comparing the species found in every zone of the transect with transect data from previous decades, you can see the change in intertidal ecosystems due to climate change.
  • We saw a California Sea Lion with the brand U374 and another with a tracker.
  • While most of the gull eggs all look the same, one particular egg is quite different.

Maintenance

  • Maya and I ran the fire pump in the morning.
  • This added a few inches to the cistern.
  • We removed the old Canadian flag and hoisted a fresh one.
  • Tazi and I removed some algae.
  • Ali whacked away at the thistles.
  • We cleaned the solar panels.

  • Over 150 sailboats from Victoria passed by Race Rocks in the late morning on their way towards the Western horizon.
  • Some of them started to return as late as 22:30.
  • The colours of their sales included: red, blue, white, fluorescent yellow, green, purple, black, orange, and many combinations of all of the above.
  • Some standouts included the Miles Davis sail and the Union Jack.
  • I couldn’t stop taking photos and ended up with dozens. Below is a selection of the best.
  • One coastguard zodiac and a search and rescue boat appeared to be accompanying the sailboats.

Last Blast on Bloghorn

Weather and Sea Conditions

North wind, 15 to 20 knots replaced the overnight southeaster and brought cool moist air and overcast skies for the morning today. In the afternoon light winds were variable and turned to light west by early evening. The barometer spent the day crawling out of the hole it was in and by 18:30 was around 1008 hPa. The sky cleared and brightened by evening. A strong wind warning is in effect. The marine forecast for central Juan de Fuca Strait calls for west wind to increase to west 20 to 30 knots early this evening and then drop to west 10 to 15 by early Friday morning. It is expected to be cloudy tomorrow with a 30 percent chance of showers or drizzle and a predicted UV index of 3, or moderate. Sea conditions were calm today once the overnight storm and morning wind chop settled down. As evening starts the wind is moving and the chop is starting again.

Vessel Observations

Three whale-watching operators were observed working in the protected area today and more passed close by through Race Passage heading out to the west and back. One sports fishing vessel was observed transiting the reserve today.

General and Ecological Observations

One Steller Sea Lion 319Y, branded on her left side, was observed hauling out on South Rocks today. She was marked as a young weaner at Rogue Reef in the very southern part of Oregon in 2013, so she is almost 3 years old.

The old male River Otter has taken to napping under the back staircase of the main house in the mornings now and one of the positive things about this new habit, is that it keeps the geese who were interested in nesting there away from the stairs.

This is the end of my shift, my last blast on the blog-horn and it is a little bittersweet to be leaving just as elephant seal show-time starts and spring develops more fully. I leave tomorrow and  want to wish the best to this wonderful Ecological Reserve, which was started by students and faculty at Pearson College. Those folks were brave enough to fight for this place, they had the fortitude and vision to found Race Rocks as a protected area. In BC, Ecological Reserve status is the highest level of protection given, by BC Parks. Fisheries and Oceans Canada protects the water area, as a Rockfish Conservation Area, so jurisdictionally that covers the sea bottom, islets (BC Parks) and the water (Fisheries and Oceans), and makes Race Rocks a de facto marine protected area (no caps).

Of course this is also a special Indigenous place with an intersection of cultures and a complex history of use and ownership by different families, groups and Nations. This is a unique, socio-ecological place to celebrate and protect. From its human history to its natural history, lets make sure that Race Rocks remains a marine protected area and is able to provide ecological education and research opportunities for future generations of British Columbians, as well as Pearson College.

Today was animal census day and the results are posted below.

Weather and Sea Conditions

Light northwest winds backed and veered bringing waves of silver and leaden clouds. Showers were visible from far away, travelling with the wind and tied across the Strait with rainbows, tops of arcs obscured in cloud. In spite of being overcast and chilly, the high was 11o C, there were brief periods of intense sunshine and the UV index was very close to 4 (moderate). Accumulated solar energy was low, about half of what we have been receiving. Just before dusk there was an intense downpour accompanied by winds over the 30 knots. It was short-lived but may foretell of what the forecaster are calling for by late morning. The barometer remained fairly steady today at ~1015 hPa but is expected to drop with the passage of a low that will bring southeast winds and showers tomorrow. Sea conditions were rough at times out in the Strait today but generally there was just a light chop inshore.

Vessel Observations

No vessels were observed in the protected area today.

Ecological and General Observations

An influx of 14 more Canada Geese kept the established geese busy on their own wild goose chase today. There were many running and aerial chases and clashes. These seem to be new animals with different behaviours than the ones who have been so doggedly determined to nest here for the last six weeks.

Many flocks of 100 to 200 Brant were observed moving through the reserve from west to east and I wonder if these are still flocks that have travelled up the coastal flyway from California and Mexico.

Harlequin Ducks are rafting up in strings of birds and moving around more than they have since I arrived nearly six weeks ago. They are usually so site-fidel that you can almost predict where they will be.

Black Turnstones continue to be the most common shorebirds on Great Race. Seeing them forage everywhere on island is a good reminder that this is essentially an inter-tidal island. Their plumage is looking new and shiny, ready for their big northern migration.

The late spring elephant seal moult is definitely in full swing now and the animals are catching up on sleep and using stored blubber to see them through the moult. Sea Lions continue to haul out on South Rocks every morning. The male Californians are also well established on Great Race in the two haul-outs near the two houses.

Work was routine today and there were no human

visitors.
