Count Day

Posted on by

The sky was partially overcast early but cleared a bit in late morning. Then it clouded over and finally started to rain as it socked in just before dark. The wind started out east-northeast then turned to west late morning before backing all the way around to southwest. The barometric pressure is rising as I write this log and the forecast calls for clearing in the morning and sunshine. Winds will turn to westerly 10 – 15 knots Friday afternoon.

Commercial whale watching vessels made fifteen observed visits to the Ecological Reserve today. One vessel regularly comes in fast and not slowing until well inside the go slow boundary and then consistently speeds up early. The same vessel can be seen hop-scotching ahead of endangered southern resident killer whales as the pass by and in the reserve, sitting almost on top of the sea otter. It is a large, noisy vessel that reliably pushes the limits of respectful whale watching and will end up by hitting an animal or worse. Most of the operators realize that this sort of behaviour is not sustainable.

Biggs Killer Whales were already being followed by the whale-watching fleet before they came into the Ecological Reserve from the east and milled in and around South Seal Rocks and the breaking rock just off the energy building. There were many sea lions in the water, some craning their necks to see better and others just trying to maintain as much time as possible in the air, by repeatedly leaping airborne. I am not sure if the killer whales made a kill or not but sense that they did. There was some fancy criss-cross swimming by the first three whales, then a little one accompanied by a bigger one arrived on scene. This was followed by a few minutes with all the whales underwater and gull action above, which made me think food leftovers. After that they left, heading south and then southeast, dogged by the fleet. Two vessels came into the reserve while the whales were already inside. It is possible that they were not aware on entering but they did not leave once they were aware of the whales’ presence.

Ecologically, the transition from summer into fall continues. Salmon migration is still strong and birds, pinnipeds and cetaceans abundant. The size of the multi-species feeding flocks on the water, is increasing daily with some aggregations (outside the protected area) appearing to have thousands of gulls.

Thursday is animal census day so here are the numbers for charismatic mega-fauna.

Routine chores continue. There were six visitors today. Two very self contained Environment Canada technical service officers came out to do annual maintenance on their weather station up on the tower. If you were looking on camera # 1 you may have had a close-up view of them at work, calibrating, replacing and maintaining their instruments in full climbing gear. Thanks go out to them as well for the help they gave us before leaving the island. Two national geographic photographers came out to get a sense of the diversity of wildlife and of course take photos. Two young people who may potentially become eco-guardians also visited. Thanks go out to Don for helping move fuel, a heavy job. Well done. Courtney drove Second Nature to get them all out here and back safely and she was accompanied by Jasper, volunteer extraordinaire.

 

 

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.

 

 

 

Killer Whales Late for Class

Posted on by

It was a clear day from glorious sunrise to subdued sunset. The wind was 5 to 15 knots in the west – southwest quadrant and solar radiation was high, though not quite as high as yesterday; 400 Langleys today and just over that on Monday. As I write the  Log blog, clouds are creeping in and blanketing the mountains on the American side and the barometer is falling again. Forecasts call for a switch to southeast winds, which usually brings wet weather. Wednesday is supposed to be increasingly cloudy and rain is supposed to follow.

Only eight commercial whale watching vessels were noted in the Ecological Reserve boundaries today and five of those were in the afternoon associated with Biggs (Transient) Killer Whales on the other side of Race Passage. The Killer Whales were on the Vancouver Island side of the passage and spent several hours in and around Bentick Island and Emdyck Passage and William Head. Several pleasure craft passed through the reserve today, all without speeding or fishing in reserve. There was one overflight during the first class field trip: a small fixed-wing aircraft that passed over west to east and then returned passing over a second time. Although one red flag was up all day at the military site there were no obvious explosions.

Pearson College students spent part of the day here today. Two of Laura Vehegge’s classes of marine science students came for their first field trip of the year to Great Race Island. I was hoping they would have a chance to see the Sea Otter, at least one pod of Killer Whales and maybe a couple of Humpback Whales, but no. After all they have just started a species list that they will be adding to for the next two years, so they will have other opportunities.

Today the students were also working on journal entries about their marine animal observations. They were lucky enough to see California and Stellers Sea Lions, Northern Elephant and Harbour Seals and lots of Glaucous-winged Gulls. There were also Mew Gulls, California Gulls and if they were sharp-eyed, Heerman’s Gulls. Those were the ubiquitous species, but for me, the more interesting and unusual species were two new, avian visitors that showed up today; a male and female Horned Lark. I send a shout out to Victoria Natural History Society on Twitter for helping with the identification. A flock of 24 Canada Geese landed and were on the island for a very short visit.

Laura’s classes witnessed the down-side of plastic in the ocean today. Is there an up-side? They had the ‘opportunity’ to observe three neck-laced sea lions. Those two California Sea Lions and one Steller Sea Lion with plastic straps around their necks will likely not survive long unless they get the specialized attention of Vancouver Aquarium veterinarian, Dr. Martin Haulena. Dr. Haulena has worked extensively with sea lions and is one of the few people able to do this sort of animal welfare work. This is another good reminder for all of us to avoid plastic if possible, recycle it and just in case it “gets away” cut all possible entanglers before disposing of it. There are a lot of really good efforts towards reducing plastic in our seas and there is a real need.

The Killer Whales mentioned above showed up late in the afternoon and missed both classes.

It was good to see Courtney with Year 20 volunteer Jasper, as a deck-hand on Second Nature. He had quickly graduated to skipper in training by the third run to Race Rocks.

 

 

 

 

Elephant Seals Hang On.

Posted on by

The overcast morning sky cleared by noon, clouds pushed out by light northeast winds. In the afternoon, the wind turned to west and then in the evening to southwest. The barometer rose to 1013 hPA today. The forecast continues to call for rain along with variable winds at 5 – 15 knots.

There were only six whale watching visits observed in the Ecological Reserve today and no sports fishers. The large military explosions punctuating yesterday’s alternate sea lion swims and haul-outs continued today.

Today was census day at Race Rocks.

A crew from operations at Pearson College, visited today and were very helpful in getting freshwater flowing again in the Eco-guardian’s House, amongst other things. Courtney was at the helm of Second Nature, Jeff brought all the plumbing gear and know-how to replace the pump and Jasper (PC Alumnus year 20) a curious, environmental engineer figured out a few of diesel pumping mysteries. A big shout out to all three. Thanks for the support.

 

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.

 

 

Strong Westerlies

Posted on by

It was a westerly kind of a day, gusting 25 – 30 knots all morning under partially clear skies. In the afternoon gusts were stronger, churning the sea into a white froth. The wind speed dropped to 20 knots in the evening and was closer to 15 by the time the sun went down. Although the fog was threatening early, it stayed off to the west and the haze that has hanging around was cleared by the wind and replaced with building clouds. The strong wind warning continues and the forecast for Monday is mainly cloudy. The barometer continues its step-wise descent.

In spite of blustery conditions and because of all the marine mammal action there were 18 visits observed by commercial tour operators today. Whale watching was good in the area today and the sea lost some salt to exhilarated looking tourists who had their hoods on and exposure suits battened down in the smaller open boats. No other vessels were observed in reserve.

It was another exciting day on the mammal front with Humpbacks all around, Killer Whales in Race Passage, an increased number of sea lions and return of at least one elephant seal to Great Race Island. Salmon continue to be an important part of gull diet in the area and that is mostly due to scavenging off kills by sea lions.

One of the California sea lions that hauled out with a big new flasher last week, has managed to get rid of it. I am not sure if the hook is inside but today he just had a little broken piece of the flasher hanging out of his mouth when I went to do the seawater sampling and when I came back it was lying on the walkway with its bead chain still looking shiny. There are several ‘necklaced’ sea lions here right now. They all seem to have white plastic strapping around their necks and it looks deadly.

There are only a few Glaucous-winged Gulls left on Great Race and not many more that are still being fed by parents. I photographed one juvenile eat salmon caviar brought back and deposited with special serving and plating effects by its parent. Lots of people think that gull is just a four- letter word associated with human garbage and super abundant. Glaucous-winged Gulls are the only species (of ten species seen here) that actually nest in the Salish Sea and their numbers have been declining for a few years now. Known in birder code as GwGu this four letter word represents an important species in the local ecosystem that is a risk due to human activity. In many areas plastic pollution poses a serious threat to young gulls that do not know better than to eat it. From the evidence so far far at Race Rocks, GwGu have been fairly plastics-free. Lets keep it that way.

Although most of the bull kelp is still very strong and beautiful, many of the stipes have epiphytic green or red algae growing on them now as they start to senesce. Bull kelp is an annual species and it grows very fast during the spring and summer. Soon the storms will be dispersing these incredible carbon sinks and some will end up on the bottom entombed in mud. Sinking plankton takes the most carbon to the bottom, helping make the ocean the world’s biggest carbon sink for atmospheric carbon dioxide. Thank you ocean, for being such a complex regulator of climate.

Ashore, the Calendula is still blooming giving new meaning to the term perennial. This plant flowers all year round here, looking as fresh in September as it does in March. It closes up when it is cold and wilts in frost but survives as a remnant of a long-gone lighthouse keeper’s garden. Native to the Mediterranean, Calendula’s bright, cheery blooms are incredibly resilient and it is one of the few plants the Canada Geese don’t eat. Although it probably shouldn’t be flourishing in an Ecological Reserve here, I am glad it is here and it reminds me that people are part of the ecosystem.

Again chores were routine and there were no visitors.

September Summer

Posted on by

The wind didn’t do much more than puff occasionally from the east southeast and the fog stayed away all day. It was a beautiful September, summer day and another one is forecast for tomorrow, (with fog patches). The barometer has been stepping down since Monday and took another step today, landing at 1014 hPA. The forecast calls for strong winds from the west.

It was an extremely busy day on the water in the Ecological Reserve today. There were 32 observed visits by commercial whale watching vessels and at times it looked like a marine Grand Central Station than a protected area. Twelve sports boats were also noted transiting the reserve and one stayed all day taking photos of the wildlife from as close as about 10 meters. Several of the sports fishing boats were speeding in reserve. Most of the commercial operators were being respectful and careful in their operations but one zodiac did go through the gap between Great Race and South Islands against the current and a couple of vessels (always the same ones…hmmm) sped inside the reserve. The commercial operators did well to not have any incidents considering the congestion compounded by the current.

There was a lot of cetacean action today with two Humpback Whales just outside the reserve to the south and two pods of Killer Whales (one Southern Resident, one Biggs (Transient) travelling past through Race Passage from west to east. Unlike the tug that was trying to tow a houseboat past and going backwards today, the Killer Whales are smart enough to use the tide to give them extra speed. At least two individuals from the Biggs group entered the reserve near North Rocks and then continued on without slowing down.

The sea lions dominate Great Race right now and their massive nitrogen contribution to the ecology of the islet and surrounding water is more than just a whiff on the air. It is pungent and obvious.

I had planned on doing some intertidal work on the low tide but had to spend the time repairing things and doing routine work that couldn’t be put off. There were no visitors.

 

Census Time Again

Posted on by

The fog rolled in last night after dark and it was gone but not far away by mid-morning. Very light winds of 5 to 10 knots came from the south, southeast, southwest and west finally settling into a west southwest pattern.

The barometer spiked mid-day at 1018 hPA and then settled to 1016. The forecast is for light a variable winds, patches of fog dissipating late morning Friday in sunshine.

Only four whale watching boats were observed visiting the Ecological Reserve today. Two of the vessels were zodiacs and two were larger vessels packed with passengers. The same vessel that has been observed and photographed speeding in reserve before, was at it again today as well as almost sitting on top of the sea otter so the clients would get a good view. The owners and insurers of that vessel might be concerned if they knew about this operator’s risky manner. Three sports fishing vessels were also spotted and recorded, speeding through the go-slow zone. There are hundreds of animals in the water inside the reserve right now and reckless vessel operation puts them at risk as well as the people in the boats.

There were explosions at Rocky Point today with minimal impact on animal behaviour here.

Today was census day and here are the results.

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.
