CBC Visits Race Rocks

Posted on by

It was an absolutely stunning day at Race Rocks, with light winds (<5kts) from the southeast and a clear sky until dusk (it has now clouded over). The barometer fell further today, to ~1010hPA. The forecast is for increasing westerly winds (10 to 20 knots near midnight) then light by Saturday morning, with a chance of rain.

It was a busy day in the reserve, with nine whale watching boats stopping by. One of the operators was even flying a drone around the island. No doubt, collecting promotional footage. Seven pleasure craft passed through going slowly, mostly. It is important to remember the speed limit in the reserve is <7kts.

We continued our training today. Learning more about the systems that keep this place running as sustainably as practicable. Don dropped Anne and Alex off at Pearson College in the afternoon, while Nina showed a CBC film crew the lighthouse. Students came out to the island at lunch for a field trip, and another group went diving off the jetty later in the day.

New Eco-guardians.

It was a beautiful day at Race Rocks, with light southeast winds and a mostly clear sky. The barometer fell a little today to ~1013hPA and the forecast for tomorrow is for sunny skies. There is a strong wind warning in effect for overnight with diminishing southeast winds Friday. Rain is forecast for Saturday.

Only four whale-watching vessels were noted in the protected area today and three pleasure craft passed through going slowly. The people on one of those vessels, the Kaos were observed feeding rockfish to sea lions in the Ecological Reserve. It is illegal to feed wildlife and if it happens they will be reported.

Today was animal census day and here are the results.

Spinus tristis :American Goldfinch–The Race Rocks Taxonomy

Posted on by

Ann Stewart, Race Rocks Ecoguardian, took these pictures of the American goldfinch ( Spinus tristis) in its winter plumage and posted them in her log of today’s date. This is the first record for this species on Race Rocks The brown nape and bright colours suggest that it is a male.  This is at the extreme northern range for these birds at this time of year. Race Rocks serves as a valuable stopover for the migration of many birds, so we assume it was on its way across the Strait of Juan de Fuca.

Golden Day at Race Rocks.

Posted on by

This morning dawn came with a mostly overcast sky and fog distant. It cleared by late morning and stayed sunny, only clouding over in the early evening. The wind was light, less than 10 knots and easterly all day. The barometer was up to 2022 earlier and is falling now. The forecast includes a strong wind warning for tonight. Thursday is expected to be sunny with a few clouds.

Four whale watching vessels were observed working in the protected area today. Several sport fishers passed through. The salmon gillnet fleet and packers passed through Race Passage heading east. There was a big swell during the morning and early afternoon.

Second Nature brought one of the Pearson College student dive teams today and the students who got into the water had a fantastic dive. Not only were they able to observe and film the incredible richness of this biodiversity hotspot, they were also visited underwater by curious sea lions.

Several new sea lion brands were noted today including Californians U20, U503, U363 and U844. One of the California Sea Lions made it right up to camera #5 today. By the time I got outside with the blog camera, he was already descending.

I noted the other day that I hadn’t noticed cookie Cutter Shark scars on the Steller’s Sea Lions. Well since I made that remark I am seeing theme everywhere, so take that back.

On the bird front, we had a little female American Goldfinch visit today. It landed on the thistles right in front of me over by the tower. Also on the bird front a suspected Brandt’s Cormorant with two leg tags was spotted today; yellow on the left leg and white on the right leg. There was also a strange bird amongst the Brandt’s Cormorants that I was hoping would be the Brown Booby that has been floating around out here.

 

Chores were routine and in preparation for the new eco-guardian crew coming out tomorrow. There were nine people on board Second Nature.

 

Steaming Up the Strait?

Posted on by

After an overcast and partially foggy start to the day, the sky cleared in the early afternoon. Winds were less than 10 knots all day from the west-southwest turning to east in the evening. The barometer rose slowly all day and reached ~ 2022h PA. The forecast is for light winds becoming easterly 10 to 15 knots early Wednesday morning. It is expected to clear in the morning and be nice on Thursday.

Only four whale watching vessels were observed in the protected area today. They all treated the protected area with respect and drove slowly and carefully. Several pleasure craft went through, one at high speed, right through the area where there were 50 to 100 sea lions in the water. The other sports fishers were much more careful.

A couple of miles to the south of Great Race, a Canadian sub was observed heading out to sea and then a few minutes later, literally steaming back to shore.

I had the opportunity to work with one of Catrin Brown’s first year biology students today. They have just finished studying ecology, so came well armed with vocabulary and concepts and were keen to soak up knowledge gained firsthand on this little biological hot-spot.

We saw evidence of food chains and food webs everywhere from Canada Geese grazing on the grass, to evidence of predation on gulls and predation by gulls. We observed the thick climax kelp forest that rings the islands and reefs and saw evidence of intertidal grazers like chitons and phytoplankton feeders like clams and mussels. We didn’t spot the sea otter that is usually here but had plenty of other marine mammals and evidence of their dining and moulting habits in the form of fish bones, fish otoliths and hair, fur and pelage (from the spring moult of the Northern Elephant Seals).

We talked about the trophic level of different types of Killer Whales and the need for protection of critical habitat for recovering species at risk. The southern Resident Killer whales are of course highly endangered and are really dependent on strong Chinook Salmon runs while Biggs Killer Whales feed one trophic level up and eat marine mammals like seals and sea lions that in turn eat salmon.

We talked about the timing of births, mating, nursing and parental care in different species and about different symbioses including parasitism ( nice worms present in seal poop) and mutualism. We talked about phenology and seasons being dominated by different types of fish and about migrations.

We even touched on the great detritivore and decomposition loops. The carbon sink that is mediated by the microbial pump that transfers carbon to deep sediments. It was an ecologist’s kind of an afternoon, a living show and tell, a time for discovery and questioning which will hopefully on reflection, lead to some deep learning.

Chores were routine and it is great to have company.

Plastic No No Band

Thanksgiving Monday was a wet day dominated by light north-northeast winds in the morning and a moderate westerly in the afternoon. Wind speed was 10 or less knots until it turned to west. By early evening it had risen to 15 – 20 knots. The barometer fell early and has been climbing since late morning boding better weather tomorrow. The wind is forecast to drop after midnight and switch to light easterlies for Tuesday. Forecasters expect a mix of sun and cloud with fog patches dissipating in the morning. A brighter day expected.

Seven whale watching vessels visited in the morning and none in the afternoon and the three pleasure craft that passed through were also in the morning.

On wet days, it seems as if the sea lions spend more time in the water although there are pockets of Californians (on the cairns, for example) that stayed put, hauled out all day. The rock-climbers also stayed where they were (up by the heli-pad), some for a couple of days. I did see one “new” (to me) brand today, California Sea Lion ‘U755’ from the Columbia River area. There was also a “necklaced Stellers Sea Lion on the rocks by the energy building today. That rock is quite popular with Stellers which surprising due to its proximity to the activity.

Six young Northern Elephant Seals were ‘hanging out’, tussling in the water by the jetty all day today.

Salmon continue to pass through, as observed in sea lion kills throughout the area. The Glaucous-winged Gulls and Thayers Gulls continue to scavenge at the surface during the kills and in the mixed species feeding flocks where diving birds force forage fish balls up to the surface. Humpback Whales continue to forage adjacent to the protected area. The Humpback out by Rosedale Reef today is an extremely large one (probably a female). It spends very little time at the surface with dive times averaging greater than 10 minutes

and sometimes only one or two blows. They are tremendously high, straight blows.

More and more Double Crested Cormorants arrive daily raising the total number of cormorants using the protected area to forage and roost. The adult Bald Eagle returns each morning and worries the gulls and cormorants.
Chores are routine and it is really great to have company.

Giving Thanks.

The morning was calm and mostly clear with very light winds (<5 knots) from the southeast. The wind picked up a little in the afternoon and switched to north-northeast by evening. The barometer peaked at 1020 hPA mid-day after rising quickly from yesterday’s low of almost 995. As the sun sets, the barometer is falling almost as fast as it rose and the forecast has a strong wind warning in effect. The forecast also calls for clouds and periods of rain on Monday along with the wind.

Five whale watching vessels were observed in the protected area. There may have been more when I went ashore for a few hours. Four pleasure craft were observed in reserve. One rental boat was observed speeding in reserve on the south side but stopped just after they were spotted and left the area slowly and carefully. There was one over-flight observed, it looked like a fisheries patrol vessel and they were high, probably one thousand feet.

One very large Humpback Whale was blowing near Rosedale Reef in the morning and there was some whale activity near West Rock in the afternoon, but unable to identify the species. Whale watching vessels were aggregating there.

The adult Bald Eagle was back on North Rock today and I counted 95 cormorants in the water just after a flock of gulls flew past alerting the presence of the eagle. As the salmon rivers start to be less busy there will be more and more eagles.

Processing some of the photos taken earlier in the fall brought to light a few showing a very young (still black) Stellers Sea Lion on Middle Rock. That might be a new record.

Red-winged Blackbirds moved through Great Race today and as in the spring they landed on the tower before heading south. There were seven on them and they may have come down to ground but I was busy and didn’t see them.

My husband is here for Thanksgiving and I am thankful

Twofold Foggy: Friday – Saturday

Posted on by

Friday started with fog again and light southeast winds, from 5 to 10 knots. By late morning there were glimmers of clearing and by mid-day the sun was shining. The wind stayed calm and it stayed fairly clear, with clouds rolling by as the wind turned to west, in the late afternoon. By evening it was still and the sky mostly clear but that must have changed as the was fresh rainwater in the morning. The barometer bottomed out Friday morning at 1007 hPA before rising briefly. It started to drop again mid-day falling until mid-Saturday. The gale warning for Saturday, came true after another very foggy morning and light easterly winds. The turn to westerly was rapid, the fog was blown off and ominous clouds with a black line on the water to the west, foretold of what was to come. It blew up fast, reaching 40 knots and then settled back down to the up and down of 20 – 35 knots. There is gale warning is still in effect and the wind is forecast to lighten overnight, then become easterly 5 to 15 near noon Sunday. (I am collecting rainwater for laundry, bonus.)

Only two whale watching vessels were observed in the protected area Friday. Two sports fishing vessels also passed through. Saturday was a little busier with five whale watching vessels noted in reserve but there were no pleasure craft, they were probably seeking shelter. It is quite possible that I missed traffic both days due to thick fog reducing visibility.

Thursday was too foggy to do the animal census so it is cobbled together from the brief time slots when visibility permitted on Friday. It is interesting to note that the gull population plummeted after the arrival of the first Bald Eagle to be seen here, since I arrived at the end of August. Not sure if that is coincidental or not.

I only noticed the eagle because of the hundreds and hundreds of gulls moving en masse, from North Rock over to Great Race. When I peeked through the spotting scope, all the cormorants were in the water, the gulls were gone and there sat an adult Bald Eagle. Only the Harbour Seals seemed to ignore its presence.

There was no sign of the eagle today and the gull numbers are perhaps even lower. Glaucous-winged juveniles and adults continue to mill around summer territories. Some young ones are still practising picking things up, flying up and dropping them. Most of the adults are fully into their alternate plumage now. Their faces recovering from the physical aspects of feeding young.

The sea lions are spending more time in the water now that their favourite haul-out spots are worse than pig pens. Some of them have turned to rock climbing and I saw the first scouts up on the heli-pad today.

6-spot the Harbour seal Observed at RR since 2008

6-spot the harbour seal observed by Pam Birley on the rock by the jetty October 9, 2015

A record for long term observation has occurred with Pam Birley of Lesteshiire England observing over a period of 7 years a certain harbour seal she named 6-spot because of the distinctive markings. Oddly enough she often gets an image of it from the remote camera 5 in the fall as it lies on the same flat rock near the Jetty.  You can see some of her other observations of it at https://www.racerocks.ca/pam-birley-photo-records/

Pam sent the picture with the note: “Hi Garry,  YES….it is 6-spot !!!!    I got a good clear view this morning as it lay basking below Cam 5.  Here is a picture. First seen 2008 I believe, that makes it seven years !!!    I love it !!!!    Pam

 

 

 

Fog the Defining Feature

Posted on by

Fog was the defining feature of today’s weather. Although visibility was up to 5 nautical miles first thing, it quickly socked in and other than a few momentary lifts and a brief clearing at dusk, the foghorn has been going steadily. Light levels were low and although it was not raining, it was very damp. The barometer started falling just after midnight last night and is still falling. There is a strong wind warning in effect for tomorrow with forecasted south winds of 15 to 25 knots in the morning. Clouds and precipitation are also part of the package.

It was difficult to see vessels in reserve today unless they passed right by the jetty and even then they were sometimes hard to spot. I heard several boats that I could probably correctly identify from their engine sounds but did not record any of those. Four whale watching vessels were noted in reserve.

No whales were sighted today due to the low visibility but I had a little visitor who was busy eating insects off the outside of the house, a Golden-crowned Kinglet. It was alternating hiding in the woodpile and catching serious numbers of insects on the house. It is a great little flyer, and able to almost hover as it picks up the bugs. A more likely place to find Golden-Crown Kinglets is high in conifers.

The animal census was put off due to the lack of visibility but my guess is that the California Sea Lion count will be high this week. They are starting to fill in between the boathouse and the shoreline west of the cairns. They are definitely damaging the cairns. One of the Californians there today had a fresh, still quite bright, red Cookie Cutter Shark scar. Many of the California Sea Lions have Cookie Cutter Shark scars. Some have quite a few while they are less common on the Stellers Sea Lions and I have not seen them on the Northern Elephant Seals.

If you didn’t know, the Cookie Cutter Shark is not very big but has this amazing feeding technique not unlike a hole saw, but much more organic. It clamps on with its lips, bites down and then spins its body around. These little dervishes will take circular plugs out of larger animals including whales, resulting in perfectly circular scars a few inches across. They have even been observed taking a chunk out of a Great White Shark. Weird but true they can also feed like regular sharks on smaller prey and they are very common. They are a vertical migrator found up to 3 kilometers down and come up to the surface at dusk, descending again at dawn.

Speaking of weird but true predation stories, a weird thing associated with the California Sea Lions is that they seem to puke up their fish bones and otoliths. The evidence is everywhere, including on each other. On that charming note, I will sign off.

Chores were routine. There were no visitors.
