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.

 

 

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.

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.

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.

 

 

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.

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.

 

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.

 

 

 

Making Sense of the Census.

Posted on by

The sun shone through a bit more today even as clouds and much needed rain continued. West winds blew at about 10 knots most of the day as the clouds were pushed steadily inland. The barometer is now back up to where it was last Friday before the big nose-dive into Saturday’s storm. The forecast looks a little brighter for Friday and Saturday before a return to wet and cool.

Whale watching activity in the Ecological Reserve was very subdued today as the black and whites moved north and east yesterday. Only four visits by commercial whale watching boats were observed in the Ecological Reserve. One sports fishing vessel and a couple of rental boats also came through obviously oblivious to the speed reduction zone within the reserve boundaries .

Thursday is census day and here are the results of this week’s animal census.

Steller Sea Lion 497

California Sea Lion 522

It is of note that there have been no Pigeon Guillemots seen since I arrived. Last year there were chicks, still  being fed by their parents, on the nests in the rubble area just west of the jetty at this time of year and later. I am hoping that the river otters have not been visiting these ground-breeding birds and will look for evidence of what has been going on there.

Maintenance work was routine and the only other visitors to the reserve were the Pearson College students having their orientation by vessel. Courtney kindly delivered paper, which was appreciated as there was none.
