Moulting Time Again: Fur and Feathers Fly

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.

 

 

 

Fresh Flag Flies

The day started with fog to the south and west and it soon crept onto Race Rocks. Sun quickly prevailed over fog and it was a beautiful day with high overcast forming late in the day. The wind didn’t do much more than 5 – 10 knots from the WSW in the morning and then turned blew gently from the south before dying off altogether mid-afternoon. It rose again from the southwest as I wrote the blog. The barometer remains over 1020 hPA after climbing slowly for a week. The forecast is calling for showers beginning late this evening, but the larger picture is much sunnier after tomorrow and there is a strong wind warning for westerlies which often bring good weather.

It was much quieter here today with only four whale watching tour vessels visiting the reserve while I was here. Five sports fishing boats transited. All stopped to look at the sea lions and no one was observed speeding in the Rockfish Conservation Area today. There were two vessels that appeared to be fishing in reserve and observations, photographs and data were collected for the enforcement team. Race Rocks is closed to fishing and is part of a DFO-enforced Rockfish Conservation Area. The islets and the sea-floor are protected by the province of BC through BC Parks.

The sea lion moult continues to be the big ecological event on shore but the timing of their visit and choice of haul-out location is no coincidence to what is going on at sea. Most of sea lions are also off foraging for part of the day and the Race Rocks haul-out is in a biological hot spot, which becomes a fish funnel for incoming migratory fish at this time of year. All six species of Pacific Salmon pass right by the front door right and there is a plethora of other species to choose from the rest of the year. Race Rocks is not a breeding haul-out nor is it a true winter haul-out as the sea lions start to arrive in earnest in July and stay into winter and early spring. There are actually some animals here all year but late summer and autumn is the busiest leading up to the peak during the chum salmon run at end of October.

GwGu juv FTThere are still some Glaucous-winged Gulls that have not left the roost but most of them are flying now and there are fewer here every day. That is probably a good thing for them as the predator that is picking them off is taking at least one per day. They are out foraging in groups trying to figure out how to feed themselves.

I went ashore for a couple of hours today and was otherwise busy with routine tasks. There are a lot of chores here and one of the challenges of living at Race Rocks is living sustainably and minimizing our ecological footprint. To do that we are very frugal with electricity and water, compost all organics, even using a composting toilet because when you make your own water by desalination it doesn’t make sense to just flush it away. Both have their chores too. Most of the electricity is generated with solar panels, which brings another set of activities to keep things going. We also pack everything out and are slowly removing unsustainable legacy items left by the light keepers over the years. A favorite chore is putting up a fresh new flag and there is one flying today.

Making Sense of the Census.

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

Harbour Seal 81

Northern Elephant Seal 2

Sea Otter 1

River Otter 1 seen (probably more)

Southern Resident Killer Whale 7 (during count week)

Humpback Whale 1 just outside of reserve but may have transited border

Canada Goose 4 full time (2 adults 2 goslings) (24 visited once during count week)

Harlequin Duck 1

Double-crested Cormorant 11

Pelagic Cormorant 12

Brandt’s Cormorant 1

Black Oystercatcher 29

Black Turnstone 95

Ruddy Turnstone 1

Western Sandpiper 3

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.

September 1st Eco-guardian Log

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

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.

Nursery Island

It was still 20 knots when we awake but the rest of the day was pretty calm from 15 knots to 22 at the most. What a change! We could see very far that day…

After so much wind we were not alone outside enjoying a normal summer day. ..We could call the rock “Nursing Island “because chicks are really everywhere and the gulls are pretty nervous never stopping between feeding the young one and watching out for danger. No way to go around without your yellow helmet like a big bill on the top of the head! Those birds hit you once but not two times and it hurts! You remember!

We had another show from Chunk and the young female in the water. She really wanted to please him! Even after weeks we are still amazed by those attaching animals. They have lost a lot of weight and are now pretty active spending a lot of time in shallow water and each time going back and forth from water to a grassy spot.

 

Desalinator and generator have been on for a few hours. Everything is working perfectly.

July 7th Chicks everywhere

July 7th Tuesday: Chicks everywhere

No more rescue boats around anymore but a tourist plane flew by the island once.

Moderate West wind was between 14 knots to a maximum of 20 knots. No fog and still a little bit of a yellow haze in the sky.
We saw Floyd and Chunk swimming closed to the South islands

From the front window of the main house we could count around 20 chicks mainly under the parent’s wings but they grow pretty fast. The adults behavior is changing they become very active doing their job, protecting each other and the chicks feeding the young ones and going fishing. They are getting aggressive. We have to wear a helmet all the time but they know us and now they just make us know that they are ready to attack. There are still a few eggs not yet hatched but not so many.
