Traffic Congestion at Race Rocks?

Posted on by

Clear skies and light winds made for a beautiful day. The wind switched around in direction going from east northeast to southeast to west and back to easterlies. Solar radiation was high at 400 Langleys and barometric pressure rose for most of the day going over 1021 hPa mid-day before dropping in the late afternoon and evening. The forecast is for more of the same; sunshine and light easterly winds until Wednesday.

There were a lot of whale watching vessels in the area today and 16 visits by commercial operators were noted in the protected area. Except for a hectic time when killer whales were passing by, most operators were careful and slow. Again a couple of the largest vessels were travelling through shallow areas , close to haul-outs and lacking room for maneuverability: areas where they should not be travelling both for conservation and for safety. Two other whale-watching vessels were speeding in reserve, apparently anxious to get back out with the killer whales or back to base. The big noisy vessel that usually speeds in and out of the protected area was very well behaved today, nice change not speeding. Five ‘pleasure’ craft were observed in the protected area. Except for a fast entry by one boat, they were all travelling slowly and respectfully, including a Pedder Bay rental boat that did a nice drift through Middle Channel while the whale watching zoo was happening in the protected area.

I continue to spot the same branded California Sea Lions, left side brands 5477, 8101, 8228, 6153, 650U and rump brands U391, U105, U601, U321, U255, U148, U118, U174, U894, U239, U223 and more. There are others as well, all photo-documented, as are the Stellers Sea Lion brands. The Northern Elephant Seals left Great Race either early this morning or last night so just the sea lions were here today in the pinniped department. There was one Humpback Whale to the south of the protected area today and a Minke Whale about two miles west. Three Transient (Biggs) Killer Whales (one male, one female and one young) passed close to Rosedale Reef, just to the south of Race Rocks, heading west.

Routine chores were much more satisfactory today with a feeling of progress being made. 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.

 

 

 

Explosions and Implosions

Posted on by

The wind blew north by northeast at 5 – 10 knots for most of today. Morning fog seemed to be blown out of the southeast but stayed on the American side of the Strait today and there was sunshine mid-day. By evening the wind had switched to west and the clouds had thickened along the Olympics and out to sea. The so-called marine air (aka fog) out to the west, had a yellowish colour of the kind you see in the haze coming into Korea from China. There may be some leftover forest fire smoke in that mix as yellow is not a normal colour for fog. The barometer continued the climb it started yesterday and reached 1008 hPA this evening. Forecasters are calling for light and variable winds and showers. I have my wheelbarrow out to catch any moisture coming from the sky and it is just starting to spit.

There were twenty visits by commercial watching vessels observed in the Ecological Reserve today and highlights included the sea otters, sea lions, elephant seals and the very large explosions coming from Rocky Point. The explosions sarted late morning and ran through the afternoon. Quite often the blasts do not seem to effect the animals but today they seemed extra substantial, of a magnitude and recurrence that cleared the islands (mostly)  of sea lions, several times. This made for some good sea lion watching in the water, as that is where they spent quite a bit more time than usual, today.

The sea lions also spent a lot of time repeatedly running for the water and then slowly climbing back out and hauling themselves up to resting spots. I doubt that this is part of a normal energy budget during moulting season. The Northern Elephant Seals remained undisturbed by the large explosions and appeared to sleep right through the brouhaha. All the moving around made it easier for photograph to see neck-laced sea lions and brands without worry of disturbance.  Two Northern Elephant Seals visited Great Race today. The young male #5850 who was here both last fall and last spring was here again today with a little female. He has really grown in the last year, especially since his spring moult. Definitely filling in and stretching out his skin. The only tag left is on the inside of his left back flipper.

There were no obvious effects from the explosions on the birds. Many of the adult Glaucous-winged Gulls have returned to their territories and are standing around on their “spots”. It almost seems as if some of them are experiencing empty nest syndrome: some pairs are doing a bit of redecorating, carrying nesting material around, acting out behaviours observed early in the nesting season last May, but with less verve, and of course ‘going gray’. The white head of the adult Glaucous-winged Gull is only white during breeding season and turns into an alternate, mottled gray during the winter. Many are transitioning now. Some adults are still feeding young gulls, although most of the young are also out learning how to forage. The youngest, or perhaps slowest one to develop, is the last one learning how to fly and spends quite a bit of time stretching its wings, taking little hops with the wings out and running while flapping. It will be aloft soon. The last Canada Goose family took flight today and hope is that they will flock off.

Chores were routine except for another plumbing challenge. There were no visitors.

Sea Lions Moulting at Race Rocks

Posted on by

There was very little wind all day and the sun came and went as clouds formed over central Juan de Fuca Strait and environs. The forecast calls for light winds to increase to westerly 15 – 20 knots this evening and then drop to 5- 15 knot easterlies Tuesday morning. The chance of showers has been pushed back to Tuesday afternoon and evening and rain is forecast for the rest of the week. The dropping barometer continued its descent and reached 1005 hPA this evening.

Today, there was only one whale-watching vessel visit, observed in the Ecological Reserve. They went really slowly in the protected area, stayed in the middle of Middle Channel and operated their vessel in a sustainable fashion. Definite candidates for the Kudos award that I give out weekly in the form of a thank-you e-mail to the company that does the best job of operating sustainably in reserve. Best practices align with the agreement made with the industry and the Marine Mammal Regulations. One sports fishing vessel was also noted. They were fishing either right on the boundary or just inside the reserve. As soon as I went out with the camera, they pulled up and left which made me wonder.

The sea lions continue to dominate the scene and the sound here. Their moult is progressing and there was hair everywhere after yesterday’s strong westerly winds. They seem to be spending more time ashore and it appears that there are more animals on Great Race everyday. This may be because less of Middle Rocks is available due to increased swell height and tide level. Photography of tags, brands and wounds continues and the data is being logged for use by NOAA scientists in determining population levels and trends, as well as migration patterns. The Vancouver Aquarium is interested in doing some animal welfare work here later in the season with “necklaced” individuals like the ones shown in yesterday’s blog, with plastic packing straps stuck on their necks and ‘growing’ into the flesh. I also take quite a few photos of sea lions that have nothing wrong with them: they are wrestling, sleeping, swimming and just hanging out. See gallery below.

More on other species tomorrow.

Chores were routine today other than creating a draft hand-out on ecologically sensitive areas for island visitors. Fence mending takes quite a bit of time each day but the sea lions are very smart so it is getting better. There was no gull guano on the solar panels this morning and I thought maybe it would soon be time to move into a every second day routine, for cleaning them. The dust and hair deposited on the solar panels turned the wash water into a deep brown in no time, so the daily wash will continue for now. Solar energy is particularly appreciated right now as I am still recovering from an almost complete loss of fresh water due to a mystery plumbing failure downstream of the Science House shut-off valve. This means running the de-salinator to make fresh water whenever there is sufficient solar power in order to not run down the batteries or use the generator. It is a bit of a juggling act but a small bother in a wonderful place with an incredible window on the world of nature.

 

 

Moulting Time Again: Fur and Feathers Fly

Posted on by

Fog gave way to sunshine by early afternoon and the west wind continued to increase from ~10 knots in the morning to 18 knots by mid-afternoon. The barometer, which has been sliding down stepwise since mid-day Monday made another step down today but remains relatively high at 1016 hPA. The forecast for Central Juan de Fuca is for more of the same but sunnier.

Except for Island Explorer, which did go through Middle Channel against the current today, there was no whale watching activity here today and no other vessels were noted in reserve.

More post-breeding gulls from other breeding areas are showing up daily including California, Heerman’s, and occasional Herring and Ring-Billed Gulls. Glaucous-winged Gull adults that are still feeding chicks are looking battle weary and changing into winter plumage. Some of their heads are a mess from constant begging and pecking by the young ones. There are still territorial disputes going on between adults and young gulls that are not their own. Fresh remains of Glaucous-winged Gulls are seen daily in different spots so I guess in a way those adults with young are the lucky ones. The gulls that are flying are feeding on salmon bits provided by the sea lions and many of the feeding flocks here are dominated by juvenile Glaucous-winged Gulls.

The sea lions are firmly into their moult now as well and spending lots of time ashore. Middle Rock is almost exclusively Steller Sea Lions except for a small hold-out at the top by Northern Elephant Seals. Large male Stellers are encroaching on their space again today but it appears more about finding a quiet place to sleep than the more aggressive interactions I saw with younger male Stellers who were scared off yesterday. Turbine Rock is also mostly Stellers while Great Race and South Islands are populated by both species together. The Harbour Seals are hauled out wherever there is a bit of separate space on North, West and South Rocks with a few on Turbine and Middle as well.

I continue to get brand, tag wound and entanglement photos of the sea lions while they are ashore. I am curious about the biomass hauled out here right now. It is a pretty incredible concentration and one of the reasons that it is a special area worthy of conservation as an Ecological Reserve. It is an honour to be here and witness what goes on a daily basis. Some of the other conservation reasons are underwater and less accessible but we are working on getting camera 2 back up and running to give a glimpse into that world too.

Chores today were routine maintenance and there were no visitors.

 

 

 

A Busy Day at Race Rocks

Posted on by

A northeasterly wind gusting 20 – 25 knots brought clouds and moisture in the morning and against the flooding tide it really made the waves in Middle Channel stand right up, creating a bit of a roller coaster effect. It was much nicer in the afternoon as the northeast dropped to ~ five knots and remained calm through sunset.

The barometer continued to rise today and reached ~1018 hPa before steadying. The forecast calls for light westerlies and some sun tomorrow with periods of rain on Tuesday.

There was quite a bit of whale-watching activity today: 20 visits by commercial operators were observed in the reserve. The sea otter is a definite attraction as are the sea lions. Island Explorer out of Port Angeles takes the sustainability prize for the day, travelling at a very low speed, staying in the middle of the channel and giving the wildlife a respectful distance. Seven sports fishing boats were observed in reserve today. Of those, four of them were speeding and one was fishing and then speeding in reserve. Time for more communications to the boating public who might not be as aware as the commercial operators about rules of conduct in the Ecological Reserve.

The sea lions continue to crowd ashore to moult and wedge themselves in tightly together in order to raise skin temperature for their important hair change. The soil here is full of sea lion hair, moulted Northern Elephant Seal skin with very short fur and is rich in guano from the nesting seabirds. No wonder the spring flowers are so spectacular. A Great Blue Heron visited Great Race today, an unusual sight here on the rock.

No visitors today. Chores were routine and entropy fighting.

Blues Skies.

The weather at Race Rocks was good for generating solar power today with clear skies overhead and a gentle west wind. At the same time, massive cloud formations were building over the Olympic Mountains to the south and the Coastal Ranges to the east. The barometer stayed up at about 1015 hPa today and the forecast is calling summer-like winds with a gale warning posted for tonight and Saturday. It is supposed to be sunny tomorrow and then return to rain for a few days.

Two whale watching boats were observed visiting the Ecological Reserve today and there might have been more. At least three sports fishing boats were in to look at all the animals in the water and on the rocks. One vessel was actively fishing in the Race Rocks Rockfish Conservation Area.

Ecologically, the transition into autumn seems to be happening with more migratory birds passing through and stopping by. The Savannah Sparrow count jumped up to ~ 15 birds today and Surfbirds to 25. Northern Phalaropes were observed feeding in the tide slicks near the reserve boundaries and more gulls in post-breeding migration, like Heerman’s Gulls and California Gulls seem to be arriving daily. See gallery below for more photos.

The weather, sea conditions and currents were also excellent for launching the whaler and doing a test run. I went ashore today and picked up Alex after doing most of the regular maintenance in the morning and finishing on return. The underwater Camera (2) mysteriously came back on-line today after unplugging and plugging back in everything Max and I could think of, to jump start it. When I checked today it wasn’t working.

September 1st Eco-guardian Log

Posted on by

It was a fairly quiet, dark and damp day at Race Rocks. The wind had still not done much by 18:00 but it rose out of the west later on blowing 20 – 25 knots. Although the ceiling was generally much higher than yesterday, solar radiation levels remained low, compared to the rest of the week, including stormy Saturday. The barometer dropped a little today, but remained above 1005 hPa and the forecast is for strong afternoon west winds to also bring much needed precipitation until Friday.

The weather pages on this racerocks.ca web site have lots of good data. If you like graphs or if you would like to learn to like graphs, check out the weekly solar radiation data graph to see how dark it has been lately.

It was another busy day for commercial whale watching activity in the Ecological Reserve with 17 visits observed. The main concerns were with a couple of vessel operators who are in a hurry and speed up before exiting the reserve. I really enjoy watching the better operators. They take their time; use the current to enhance their visit and make sure that their clients have a good experience, while assuring a sustainable future for their industry in the Ecological Reserve.

Four groups of Pearson College students visited the Ecological Reserve today as part of their orientation week activities. They were in the two vessels Haiku and Second Nature.

More sea lions appear to be arriving daily and I look forward to doing the census later this week. I have also documented a number of branded and tagged sea lions and data that will be shared with NOAA biologists. Today there were two Northern Elephant Seals on the island, the young male from the ramp yesterday moved up behind the boathouse and a similarly sized individual arrived on the ramp today with a crowd of California Sea Lions. Only one Elephant Seal was visible on Middle Rock, surrounded by Stellers Sea Lions.

Other less welcome arrivals were ~24 Canada Geese. I guess now that there are a few green shoots again; they are here to eat them. There is still a family of five, whose goslings were late to hatch, that looks like it hasn’t left yet.

I was busy with minor chores today, including the usual plus repairing the jetty fence twice, cleaning the camera, running the generator to bring the batteries back up and assessing generator use, de-salinator hours and various fuel quantities on hand for month end. I did make time to take a few photos and have included them in a gallery for your viewing pleasure.

Cool and Wet

Posted on by

The cool, wet weather these last couple of days at Race Rocks was a long time coming and the ceiling is still thick enough so that peak solar radiation levels are about half the norm for this month. The little bit of soil is sucking up the moisture and there is already some visible return of green, a colour almost defeated by the drought. The wind didn’t do much until late afternoon today and there was no wind most of the morning. By early afternoon it was up to 10 knots southeast, only to fall off again as it swung to a feeble southwest in the evening. The barometer continues to crawl out of the hole created by Saturday’s storm and it is almost back up to 1010hPa. From the forecast, it looks like periods of rain will continue as the cold front moves southward over the next few days and then we will be back into the summer pattern of westerly winds and possibly sunshine, if not fog.

There was quite a bit of whale watching activity in the area today. There were 18 visits made by commercial boats operating inside the Ecological Reserve and more outside. All but two vessels abided by the rules, taking it slow, being respectful and courteous to each other and mindful of the large concentration of animals in this protected area. From the radio chat and observations, I was able to ascertain that there were both Biggs’ and Southern Resident Killer Whales in the vicinity. Both pods passed just outside the reserve heading west about a half mile to the south. There was also a humpback feeding just east towards Victoria.

One, large, whale watching speeder may have taken his cue from the only “sports”-fishing boat that came into the reserve today. A Grady-White-type boat with halibut gear, came inside behind a line-up of whale watchers and then roared off from inside Middle Channel as if his urgency trumped the wildlife values in this congested area. Later one of the well respected companies had a large vessel observed taking off at speed after a visit to the sea lions, closer than 100m. I hope the animals in the water were able to get out of his way.

There were a number of sea lions with major wounds noted today and I will try to photo-document them on a drier day. Of note were fresh, severe gashes on at least three Steller Sea Lions and what appeared to be propeller marks on two Californians. Most of the sea lions spend their time sleeping when they are not off foraging or tussling with each other. The Californians that are awake though, are always barking.

I tried to document three branded California Sea Lions today but only succeeded in recording one full number without question, # 8228 on the left side. I got one partial # U_05 on the rump and another partial #U14__. I didn’t see any branded Steller’s yet.

The pre-summer cast of avian characters, is back and it is really a privilege to be here again to witness Race Rocks as the change to autumn happens. I saw at least 95 Black Turnstones busy foraging all over the island today. They roost together on the south shore in the evening, making it easier to get a good count . They are back from a summer away at nesting sites along the western Alaskan shores of the Bering and Chukchi Seas. Cormorants probably didn’t go far but the Double-Crested Cormorants I saw today definitely do not nest in the reserve.

Most of the Glaucous-winged Gull chicks have fledged and left the island but there are still a few slow pokes who are busy begging from worn-out looking parents for food. Amazingly some adults are feeding three big chicks that appear larger than the adult. There is evidence of fresh predation on these young gulls and River Otter is the prime suspect as it seems to be nocturnal or crepuscular activity and one of the remains was dragged right in to the otter den entranceway. As was noted last year, it appears that the head of the gull is enveloped in its neck skin as if the skin was torn and pulled up like a turtle-necked sweater coming off inside out.

A newly fledged Glaucous-winged Gull still not confident enough to fly away on a new adventure.

The Northern Elephant Seals surprised me. I knew there was one here on the marine railway ramp on Great Race because Guy and Christine had mentioned it and it hauled out just before they left yesterday. It is a really well fed young one, completely plumped out since I last saw them after their horrendous moulting fasts of the late spring. Another five Northern Elephant Seals are visible with the scope from the top of the tower, on Middle Rocks amidst the sea lions. Of the five, one appeared to be very small, perhaps young of the year and the other four were larger juveniles perhaps including a small adult female. I will try to get a better handle on this in the days to come.

There were no visitors today as I got back into routine chores and was constantly reminded of the incredible natural setting that makes this place so special.
