There was nothing remarkable about the leaden morning with light and languid, north-northeast winds. Partially overcast skies cast a silvery pall over the Strait but bits of blue sky held promise for better things to come. The barometer held overnight at just above 1010 hPA and by mid-afternoon had dropped to 1008 As evening falls the barometer is holding at 1007. In the afternoon there was some sunshine but it was really a day dominated by cloud.

Five commercial whale-watching vessels were observed working in the Ecological Reserve today. Three were seen working in behind (south side) South Rocks and they were travelling very slowly and cautiously. Sea conditions were calm. The sea lions did not appear too disturbed by their presence. A few younger animals close to the water went in but it would be difficult to determine cause. On that note, military blasting continued as planned, from late morning to mid afternoon. Interceptor vessels and red flags warned boaters off. The sea lions and birds did not seem to react.

The wild goose chase continued and progress is happening. By early afternoon, most of the geese had retreated to the military zone to graze on the large lawn there. One pair staking out an area by camera 5 were more persistent, but eventually left for greener pastures. A couple of pairs of gulls were seen doing some of the broody things they do when nest building but as it is early yet, they are probably just practicing for the big day when they actually start to build a nest. The Pigeon Guillemots continue to flock here in the morning and leave in the afternoon as noted by Riley. Many were practicing walking on land today and in the water they worked the ebb flow through the rocks taking a ride and then flyew back upstream for another one.

A partially decomposed Northern Elephant Seal pup and part of its skull was located not far from the octopus in the boulders beach east of the Ecoguardian’s house. From the size, it appeared to have been a very young pup, if not premature, at death. The octopus was bigger. The plentiful, rich food sources are starting to explain the large number of eagles here daily.

A branded Stellers Sea Lions was photographed today 319Y and 4332 was observed. A California Sea Lion with a number on its rump and an X anterior to that was observed but the number was not verified nor was a successful photo taken.

 

There were no visitors and chores were routine today.

  • The female elephant seal that hauled out yesterday onto Great Race gave birth overnight on the lawn between the science centre and the desalinator bunker.  The pup looks big and healthy.  Several birds have been sneaking in to snack on the placenta and umbilical cord.  Also the amniotic sac was visible on the lawn nearby.  The mother has what appears to be a pale green flipper tag with very worn out ID numbers. ( greenish- tag # 5928)
  • Chunk was more interested in mating than in checking out the new pup.
  • A west wind picked up over the day up to 40 knots in the evening gusting close to 50 knots with heavy raiin.

Maintenance

  • Month end reporting
  • Cleaning, packing, tidying for shift end.

Ecological Happenings

  • After last nights’ strong winds, many of the regular Sea Lions on the North East of the island were not there, but returned towards the afternoon.
  • Four Elephant Seals were on the dock (where the California Sea lions usually lay), including one pup. The pup was tagged (B228). It had a hard time getting off the dock to return to its mother (see photographs below)
  • Great Blue Heron, spotted today by Camera 5 on the high coastal rocks
  • One more tangled Sea Lion was spotted in preparation for the Vancouver Aquarium rescue on the 28th of October. The two that were previously sighted, could not be found today.

Marine Vessels

Four tour boats, no fishing/pleasure vessels seen today.

Maintenance

  • Davis weather station was offline – this has been resolved.
  • Troubleshooting the pressure hose, in preparation of some cleaning on the island.

Plastic No No Band

Thanksgiving Monday was a wet day dominated by light north-northeast winds in the morning and a moderate westerly in the afternoon. Wind speed was 10 or less knots until it turned to west. By early evening it had risen to 15 – 20 knots. The barometer fell early and has been climbing since late morning boding better weather tomorrow. The wind is forecast to drop after midnight and switch to light easterlies for Tuesday. Forecasters expect a mix of sun and cloud with fog patches dissipating in the morning. A brighter day expected.

Seven whale watching vessels visited in the morning and none in the afternoon and the three pleasure craft that passed through were also in the morning.

On wet days, it seems as if the sea lions spend more time in the water although there are pockets of Californians (on the cairns, for example) that stayed put, hauled out all day. The rock-climbers also stayed where they were (up by the heli-pad), some for a couple of days. I did see one “new” (to me) brand today, California Sea Lion ‘U755’ from the Columbia River area. There was also a “necklaced Stellers Sea Lion on the rocks by the energy building today. That rock is quite popular with Stellers which surprising due to its proximity to the activity.

Six young Northern Elephant Seals were ‘hanging out’, tussling in the water by the jetty all day today.

Salmon continue to pass through, as observed in sea lion kills throughout the area. The Glaucous-winged Gulls and Thayers Gulls continue to scavenge at the surface during the kills and in the mixed species feeding flocks where diving birds force forage fish balls up to the surface. Humpback Whales continue to forage adjacent to the protected area. The Humpback out by Rosedale Reef today is an extremely large one (probably a female). It spends very little time at the surface with dive times averaging greater than 10 minutes

and sometimes only one or two blows. They are tremendously high, straight blows.

More and more Double Crested Cormorants arrive daily raising the total number of cormorants using the protected area to forage and roost. The adult Bald Eagle returns each morning and worries the gulls and cormorants.
Chores are routine and it is really great to have company.

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.

 

After the Autumnal Equinox.

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.

 

 

 

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 Whale of a Day.

Posted on by

The weather on Race Rocks was variable today. We started with drizzle, overcast and fog. The fog came and went until early afternoon when it cleared. The wind, which was westerly, picked up a bit in the afternoon and was still blowing 15 – 20 west, as I finished up the log after sunset. The barometer started a descent yesterday that continued today ending at 1016 hPA. This matches the forecast which is calling for showers tonight. There is also a strong wind warning in effect and overall it looks like more good weather coming.

There were 18 observed visits by whale watching boats to the Ecological Reserve today. Most of the operators work carefully, respectfully and sustainably, they slow right down on entering the reserve and go even slower when there are seals and sea lions in the water. If there are whales in the Protected Area they do not enter into the Ecological Reserve and if whale enter while they are inside they carefully and slowly leave using extreme caution to avoid interacting with the animals. They stay in the centre of Middle Channel going with the current and never try to wedge themselves between Great Race and South Islands (their insurance companies probably like this too). They are respectful of their distance to the animals and a role model for other companies and vessels on the water. In the long run, this is good for business and good for the animals. It means that this kind of commercial activity might be able to sustainably continue to use the Ecological Reserve for profit making.

Today was a day with lots promise for Southern Resident Killer Whale recovery. L-pod has another brand new calf, born sometime on or before September 5th. The significance to Race Rocks is its’ central location to this babies’ first few days of observed activities. This is the fifth Southern Resident calf born since last December and it renews hope for recovery of this very endangered population. To give you an idea of how significant this is: 1977 was the highest ever recorded year for Southern Resident calf production with nine calves born. According to the Center for Whale Research no calves survived in 2013 and 2014, so 2015 is a boon.

Killer whales and salmon are both almost iconic to our identity in this part of the world and of course they are completely linked together, especially here at Race Rocks, which is an oceanic salmon funnel, a condensed part of one of the planet’s largest salmon runs.

While celebrating this success, let’s also do more to continue their recovery by modelling more fundamentally sustainable behaviours, like using less water, eating sustainable seafood, recycling, using fewer harmful chemicals, electricity, fuel and plastic, doing shore cleanups and working for positive change through democracy. I have digressed, so back to biology: this new calf was seen with L91 (probably the mother) and has been officially named L122.

At this stage of writing the log, I looked up to see several Humpback Whales going through the Ecological Reserve from west to southeast. It looked like three animals; a very large one, (probably “Big Mama” a name used by whale watchers) and two others, one much smaller, which may have been a calf. I headed out to photograph the whales and witnessed some whale watching vessels making a bee-line for them, even though the whales were inside the Ecological Reserve. Speaking of sustainable behavior, the agreement states that if there are whales inside the reserve, the whale watching boats stay outside. Two vessels came up tight behind them and a third came in around the front of their path, the other vessels following the whales dropped off staying outside as per agreement.

The whales were in fairly shallow water between South Islands and Rosedale Reef, next to a kelp bed, so didn’t have a lot of maneuvering room with two boats behind and one in front. I went up the tower and took more photos.  I totally commend the vessels that left the whales and turned to travel outside of the reserve instead of following the whales and other vessels into the Ecological Reserve.

I did a few chores and went back to writing. This time when I looked up there was a pod of Killer Whales heading into the reserve on basically the same track as the Humpbacks but a little closer to Great Race. I went back out for more photos and saw a group of about fifteen Southern Resident Killer Whales, members of L-pod according to the whale watchers. There was a little calf travelling at the back of the pack with a small adult animal, probably a female (?). Not sure if it was the newest one.

I took a lot of photos today and will share them over the next while. It was a busy day with regular chores, spotting and phtotographing the 10 Elephant Seals that have recaptured the top of Middle Rocks and are scaring off sea lions, photographing sea lion tags and brands, gulls and of course the whale shows. With all that going on it seems odd to say, there were no visitors.
