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.

Sun-Monday Log: Double Billing Blog

Posted on by

Two more, lovely, sunny days squeezed in with the barometer down at ~ 1010 hPA and dropping. Light southeast wind today and yesterday will switch to variable and east on Thursday and the forecast looks like a change towards showers and southeasters towards the end of the week.

Ten visits by whale-watching vessels were observed in the Ecological Reserve each of the two days being reported. A handful of pleasure craft came through as well and everyone except the same guys who are always in a hurry and one boatful of lucky fishermen, were well behaved. The fishermen were lucky as they must have lost power and were swept over the little reef by Turbine Rock. One was ready with a paddle and the youngest one got the kicker going which got them out of there (eventually). That was exciting, especially for them. Eight kayaks came through the reserve yesterday. The paddlers at the front came through without disturbing any of the animals hauled out. The weakest paddler came by on her own, last. The tide pushed her a bit too close the Middle Rock and the sea lions stampeded. Sometimes it doesn’t take much.

Humpback Whales are feeding close if not in the reserve just about every day now. The individual spotted by the Marine Science students is feeding downstream just to the west of Middle Channel, during ebbing currents. I am curious if it goes down and just orients itself into the flow and filters away. There is a lot of food in the area and large multi-species feeding flocks driven by diving birds such as Common Murres and all three species of cormorants. The gulls, and there are a lot of them, roost on Race Rocks and then rush out to the feeding frenzies which I am assume are either small schooling fish like herring, sand lance or anchovies and/or large zooplankton like krill. These crustaceans are also known as Euphasiids and they look a bit like tiny shrimp with really big eyes. Those are the same sort of treats that Humpback whales like to feed on with their baleen and they use their really big fore flippers that are white on the underside, to herd krill and forage fish.

I have come to realize that the Glaucous-winged Gulls are still sitting around on the territories. Something I didn’t notice or understand last year until the spring shift and then I thought that they had just come back from somewhere. The juveniles that were raised here are mostly out foraging but also sometimes ‘hang-out’ where they were raised and also do a fait bit of begging from their parents. This week a lot of them have been practicing picking objects in their bills, flying with them and dropping them. Not sure if they are working on their aim but have noticed rocks, chunks of wood and bark and clumps of vegetation on the walkways. Yesterday morning I found a rock on the roof of the energy building and when I looked around saw the damage done to one of the solar panels.

Other birds seem a lot more refined. It is so nice to see the Harlequin Ducks back again, they are a favourite of mine. More and more Surf Scoters are flying through from west to east and it seems that fall is in the air.

 

Chores were routine both days and there were no visitors.

It was a glorious October day with sunshine and light southeast winds. The barometer slid down to almost 1015 hPA but the forecast looks good with more light winds and sunshine.

Only two whale watching tour boats were observed visiting the Ecological Reserve today. Several ‘pleasure’ craft came through and only one speeder was observed, two young men in a rental boat.

There are more and more California Sea Lions and they are damaging the burial cairns and the area above the boat shed where the rare plants used to live. Where ever they haul-out for more than a few days becomes quickly burnt looking and devoid of vegetation. Today they knocked down a big boulder from above the boat house onto the walkway. The Canada Geese have returned as well and are stubborn about staying so it feels like an invasion. The Stellers Sea Lion numbers are staying steady and individually they seem much wiser and wilder than the California party lions. The Northern Elephant Seals sleep amongst the Californians and are much less reactive than either of the two sea lion species.

Chores were all about fighting entropy today. The sunshine was a bonus for power generation and making fresh water. There were no visitors.

Gathering of the Gulls

Posted on by

Today started fairly clear, then clouded over. In the afternoon it was sunny for a few hours and eventually the sky darkened and at dusk the rain started. The barometer rose to almost 1019 hPA mid-day and then fell. The forecast is for clearing and light east winds with sunshine on the horizon.

Twelve commercial whale-watching vessels were observed working in the Ecological Reserve. They were in the area watching a Humpback feeding very close to the western reserve boundary, transient orcas to the southwest and southern resident killer whales to the northeast.

Today was census day due to thick fog yesterday.

In the Fog.

Posted on by

The sky was mostly clear in the morning but fog moved in and dominated the rest of the day. The wind switched from east northeast around to west in advance of the fog and then blew fairly steadily west at 20 – 25 knots. The barometer held its own today at and around 1014 hPA. There is a strong wind warning in effect expecting west 20 – 30 this evening and again late afternoon, evening on Friday. There is a chance of showers on Friday and then it is supposed to clear again.

In spite of the thick fog in the afternoon, eight whale watching vessels were observed working in the Ecological Reserve today. Two “pleasure” craft were also observed, and one almost ended up on Middle Rock. The ebb tide was sweeping swept out to sea as they tracked across from North Rocks and they were pushed into the kelp bed just before Middle Rock before they adjusted course and powered out. They were lucky to not have been stalled by kelp in the wheel.

Ecological observations were limited by visibility today. I could hear the whale watchers talking about a Humpback Whale in the vicinity but did not observe it. The animal census will have to wait until there is visibility. The Canada Geese are arriving after dark now and taking up other stealth tactics to stay on Great Race.

Fog remained thick at the end of the day. Chores were largely Sisyphean in nature as keeping the California Sea Lions away from the houses and buildings becomes a more and more Herculean task given the resources. There were no visitors.

 

Sumo-sized Sea Lions

It was a copycat kind of day, weather wise, the same as yesterday and the day before. Calm, very light winds and clears skies. The barometer continued the drop started on Sunday and is now below 1012 hPa again. The forecast is calling for a switch to light winds west 10 -1 5 and a mix of sun and cloud until Friday when showers are expected..

Whale watching traffic in the Ecological Reserve was fairly light with only eight observed visits. All the operators did really well today. They slowed on entry, went with the current, drove in a responsible way that respected the protected area and saved speeding up until they were clear of the reserve. This is the sort of cooperative behavior that is the norm for sustainable operations in reserve. Observations were made of “sports” fishers hauling in lingcod and rockfish in the Race Rocks Rockfish Conservation area.

Although there may have been more elsewhere, there was no lack of whale action around Race Rocks today. Three Biggs Killer Whales were spotted travelling from east to west through Race Passage in the morning and a Humpback Whale went the other way, in the afternoon, spending some time feeding close to North Rocks. There large multi-species feeding flocks in the same area. Perhaps there are balls of forage fish there.

I saw a large kelp raft, first of the season, sweeping out to sea with the ebbing tide today. This annual kelp becomes more and more prevalent in the tidelines as autumn progresses and the winter storms will remove most of it before spring. It is a great carbon sink that fixes large amounts of carbon, which will eventually become entombed on the bottom. Not all of it goes out to sea and sinks though. Kelp that lands on shore is a key part of near shore food webs relying on this large volume of rotting biomass to fuel new generations of shore spawners and out going young salmon.

Chores were routine again and the sunshine is allowing for recovery of freshwater lost earlier in the month. The level is almost back up to where it was on September 5th. There were no visitors.

 

Vibrissae to Vibrissae They Faced Each Other.

Sunrise saw the big moon ‘dropping’ in the west this morning and clear sunny skies reigned supreme all day. The falling barometer continued its descent today but the forecast looks good with today’s light easterly winds continuing tomorrow.

Fifteen whale watching vessel visits to the protected area, were observed today. Speed on arrival and departure continues to be an issue with a few operators however the large majority of operators are driving at a slow, respectful and careful speed. A couple of the larger vessels with shallow draught are acting more and more as though they are little speed boats weaving in and out of the rocky islets, in areas which are, by agreement with the industry, off-limits. The agreement was established by consensus, to ensure sustainable whale watching operations within the protected area. Just in case institutional (or other) memory has been lost: travel is supposed to be confined to Middle Channel, going with the current. All of the companies using the Ecological Reserve for profit should be thinking about the example they are setting for pleasure craft and the sustainability image of their company (not to mention their marine insurers who would probably not be too happy about the risks being taken by the few).

Minke, Humpback and Biggs Killer Whales brought the whale watchers to the area today and the seals, sea lions and sea otter brought them into the Ecological Reserve. At low tide the sea otter can be seen in the kelp bed on the southeast corner of the reserve but I am not sure where he goes at high tide. He has moved back there after merciless whale watching traffic as close as was physically possible. While it did not appear to ‘bother” him having large powered vessels lurching over him, decks crowded with people gawking and taking photos, I can certainly understand the move.  The Bigg’s Killer Whales travelled west past Race Rocks today again using the shallow Eemdyk Passage behind Bentinck Island, which is directly across Race Passage from Race Rocks. Quite a few Harbour Seals haul out in there. There was a Humpback Whale feeding next to Church Rock in the morning and a Minke Whale travelling to the east was observed just east of North Rocks. There were Southern Resident Killer Whales in the area according to the VHF radio but I did not have a chance to spot them.

I did have the opportunity to observe some Stellers Sea Lions and take a few photos of two younger ones playing together and an older “couple” that seemed quite wise. I know that may sound anthropomorphic but what I observed was the animal on the left licking the neck of the big old bull and then the two muzzling each other gently lip to lip. It was the gaze of the big old male that seemed to tell a story about a long life. I can’t really explain it so here is a quote from Carl Safina who is very articulate about animal’s inner lives.

“We have no trouble saying that an animal who’s vigorously eating is hungry, and one resting after exertion is tired; yet we can hardly force ourselves to acknowledge that when they’re playing they’re having fun, or that when they’re acting affectionate they’re feeling the bond,” Safina said. “Why? Because denying them all experience reinforces our favorite story: that we are so very special.”

On the sustainability front, today was a great day for solar power and I made lots of fresh water with solar power using the desalinator. Chores were routine and there were no visitors.

 

Sisyphian Struggles with Sea Lions

Posted on by

It was another beautiful day at Race Rocks with light north-westerlies turning to west and the barometer climbing considerably higher than it has in a week. The forecast is for more of the same with light winds – easterly in the morning then switching to west.

A few commercial operators were working in the Ecological Reserve today including one boat that calls itself a party boat. It came in fast and then went back and forth through Middle Channel seven or eight times before leaving. They also sat right in the middle of the current running against it but staying stationary for long periods of time. Strange but true.

The usual Saturday morning dive charter was here with divers in the water right in front of the sea lion haul-out on north Great Race, also as usual. Total, there were five tourism vessels working in the protected area, including three whale watching vessels. Only a few pleasure craft went through today. Most of them slowed and followed the rules. The exception was a rental boat that went through the reserve at high speed, stopped, changed direction and then roared off at full throttle right through an area with lots of animals in the water.

The ecological trends described in the Log during the last week continue as do the difficulties of identifying gulls, especially large numbers of multiple species, with different ages and stages of plumage all stirred up with hybridization and lots of exceptions to the rules. Yes folks, gull is officially a four-letter word and the jury is still out on some identifications.

The sea lions continue to haul out and it seems that there are more Stellers Sea Lions hauling in the last few days, especially on Middle Rocks. Perhaps they are relaxed enough to haul out, after a day or two without explosions across the way. The extra sea lions on Middle Rocks may be why four young Northern Elephant Seals showed up at Great Race today; #5850 and three companions, all about the same size or smaller, two males and a female (the smallest).

Chores consisted of fighting entropy, not unlike Sisyphus, with similar results. There were no visitors.

 

 

Killdeer Calling in Daylight

Posted on by

The sun set behind Makah and Clallam territory on the American side of the Strait tonight meaning that autumn is the new reality. What a glorious end to a day that just kept improving. Serious clouds followed earlier heavy fog and the threat of rain was kept at bay by light and variable winds, most of the day. The wind finally turned to west 15 – 20 and the sky cleared. The barometer stayed above 1015 all day and the tendency now is rising, which bodes well for tomorrow. The forecast is calling for some clouds and a 30% chance of showers tomorrow followed by a mix of sun and cloud.

There wasn’t much vessel traffic in reserve today, just a couple of well behaved pleasure boats passing through and three whale watching vessels.

The young male Northern Elephant Seal #5850 returned to haul out up on the grass at Great Race Island today. He was tagged in Ana Nuevo Island as a weaner in 2012 and has now lost all but one of his tags. Today he had a male companion about the same size and they spent a little time sparring before falling into deep sleeps. The little female he was with last time spent most of the afternoon asleep underwater, on the bottom, just off the jetty.

Every night at Race Rocks just after dark I hear Killdeer calling and today I had a chance to see them in daylight, which is a rarity; beautiful birds with very large eyes.

I would love to know where they usually go during the day and why they fly out to Great Race for the night.

The number and diversity of gulls here right now is a little staggering and there are a few that I am having trouble identifying. There is one with yellow eyes like a Herring Gull but smaller in stature with a smaller less fierce looking head. Do Thayers and Herring Gulls hybridize now?

Other than re-stringing the jetty fence, chores were routine today and there were no visitors.

 

After the Autumnal Equinox.

Posted on by

The day started clear with clouds distant, to the east. A steady north by northeast wind of between 5 and 10 knots seemed to gradually bring the clouds around but Race Rocks remained in the donut hole as it often does, with sun dominating until late afternoon. The barometer is holding steady, if averaged over the last two days at ~ 1014 hPA, but the tendency now, is falling again, at the end of the day. There was no colour for sunset as the clouds built and the forecast calls for showers for the next few days, with easterly winds turning to westerly and fog patches dissipating near noon tomorrow.

It was a quiet day on the whale-watching front with only four visits to Race Rocks Ecological Reserve by commercial operators. There was an equal number of “pleasure” craft but they were not all as well behaved, with one of the Pedder Bay Marina rentals fishing in reserve. The marina is now able to track their rentals using GPS. They are really good about contacting their renters, when called and persuading them to move out of the Rockfish Conservation Area which is closed to sports fishing, for finfish in the Ecological Reserve.

There were repeated explosions across the way. A good ending for explosives I suppose, if you consider the alternatives. It seems to make the sea lions jittery and by that I mean more likely to stampede and go into the water. The Stellers seem more sensitive to disturbance in general.

Ecologically, the sea lion moult continues, elephant seals are trying to get up onto Great Race but there are a lot of sea lions in the way. Northern Elephant Seal # 5850 was back again this morning but didn’t make it up the ramp due to sea lion congestion. Later I saw him doing the ‘wave’ up the rocks in front of the Science House. Another individual seal joined the sea lion mosh pit east of the Eco-guardian’s House and others still hold their own on the top of Middle Rocks completely surrounded and outnumbered by Stellers Sea Lions but not bothered. The Sea Otter has been absent for a couple of days.

Bull kelp stipes are becoming more and more covered with epiphytes and their blades are loaded with spore patches increasing chances of a good settlement for the next generation. Cross jellies and barnacle moults continue to dominate the large zooplankton visible to the naked eye and the phytoplankton bloom has cleared which probably means either a crash or more likely lots of grazers like copepods and euphausids (aka krill). What ever cleared the phytoplankton certainly improved visibility into the water considerably. It is pretty cool to watch the big Steller’s Sea Lions ghosting through the kelp forest.

Black Oystercatchers are back, congregating on Great Race after an absence. More gulls and cormorants arrive in the area daily. There continues to be large, mixed-species feeding flocks including gulls and divers and multi-species gull feeding flocks associated with sea lion salmon kills. Salmon and halibut continue to swim past and around Race Rocks as evidence by the predators in the area, including human fishers talking about their catches on the radio. The Canada Geese are attempting a come back and it is difficult to keep them off as they just sit on the water waiting for the coast to clear. Every night the Killdeer return to Great Race as night falls.

Sea Lion brand and entanglement photography continues as do the daily chores to keep this place running sustainably. There were no visitors today.
