Sumo-sized Sea Lions

Posted on by

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.

Smokey Skies

Posted on by

The wind was still, early this morning. It didn’t really start moving until mid-afternoon, 5 – 10 knots from an east-southeastly direction. Although it was sunny, there was a haze in the air that made for a blazing sunset last night and sunrise today. I am curious if this is smoke, all the way from Squamish, where there was a big creosote wharf fire a few days ago?

Are these red skies in the evening and the morning a result of the Squamish wharf fire?

The barometer rose slowly until about noon and then it started to slowly fall, nothing dramatic and no strong winds. The forecast is for more of the same, with afternoon westerlies tomorrow.

Three whale watching boat were noted in the Ecological Reserve today. The last whale watching vessel of the day, idled slowly through, keeping a deferential distance away from the animals, Tourists were out on the bow, shooting pictures of the blazing sunset and lounging marine mammals. It was a tranquil scene. No sports fishers were observed either speeding in the Ecological Reserve or fishing in the closed area, although several passed through at speeds respectful of the wildlife in the area.

Passive Northern Elephant Seal data collection continued. As luck would have it, all seven animals that had been sleeping in the garden, woke up and decided to go for a swim late morning. This allowed me to take their photos as they passed by the measuring device. I was also able to get some photos inside mouths for dentition information while they were wallowing around gargling saltwater and ‘wrestling’. Tagged animal #5850 continues to hang out as one of the seven ‘gardeners’.

Dentition changes with age and can be a health indicator. Say ah.

A branded and tagged California Sealion # U 902 was noted hauling out on South Islets this afternoon. Note the large range of sizes of both species.

California Sealion branded and tagged U902 also read as C902 C is for the mouth of he Columbia River where it was born.

There are still three pairs of Canada Geese trying to establish nest sites and they are having a hard time finding territories on this tiny island that already has at least nine Canada Goose nests. Maybe they will head over to Vancouver Island where there is more room. Their territoriality can get in the way of other species having a piece of the very small island as they chase off, not just each other, but Glaucous-winged Gulls, Black Oystercatchers and Pigeon Guillemots.

There were no visitors today. Maintenance chores were routine.  About 9:30 PM the phone/Internet went down for the seventh time since I arrived. Even that is becoming routine.

Its a blast… really many blasts.

Today there was a lull in wind velocity. The west-southwest wind continued and even pushed more from the south for a few hours in the afternoon, but the speed was less than half of yesterday’s winds.

It was a bright day even though it hazed over in the late afternoon. This graph of accumulated, daily solar radiation for the last week shows up the big differences between days depending on cloud cover. The metric, one Langley is equivalent to 41.84 kilojoules per metre2. Check out the weather pages of this web-site for more nifty graphs and information.

The barometer rose today, levelling off and even dropping a little, late afternoon. The forecast is calling for a day similar to this one.

There were no tour boats in the Ecological Reserve today. Two sportsfishing boats were jigging very close to the boundaries but probably not inside and one aluminum water-taxi like sportsfisher went through the main channel at high speed. A derelict looking fishing vessel, called the Larkin, was towed by a tug, through Race Passage adjacent to the reserve, late afternoon.

Military blasting, as promised, was conducted during the business day. Even during and after the biggest explosions, the largest reaction I observed were sealions raising their heads and looking alert for less than 30 seconds.

Speaking of alert (or not), a total of nine Northern Elephant Seals were hauled out on Great Race today. The four in the garden were joined by two young amorous animals and a third sub-adult male. There was a bit of a kerfuffle involving the biggest male but they all settled quickly as it appeared that conflict was just too energetic.

The new (to me) female was well tagged with a left double tag of #7620. The right side was still double-tagged but much more difficult to read with # 7688 confirmed. One of the right tags was yellow instead of the lime green and very worn. Tagged animal # 5850 (left) returned. The animal with psoriasis continues to sleep soundly, off on its’ own right, beside the path and only occasionally, barely opens her eyes when I go past her.

These tags are very important to elephant seal biologists who study the population dynamics: (How many are there? How is the population doing? How long do they live?); the distribution (Where do they go and when?) and the phenology (When are individuals pupping, nursing, mating, and moulting?). The dual/quadruple tags help statisticians test assumptions made about re-sightings so that their mathematical models are more rigorous. We have a lot to learn from this resilient species that has recovered from the brink of extinction and (so far) avoided the pitfalls of genetic bottlenecking.

There were no visitors today and chores were all routine maintenance.

 

 

April 12

As the sun set, the wind shifted around to south-southeast after blowing about 10 knots  from a westerly direction most of the day. The snow line across the Strait is very low and the chill in the air continues. Although there was some sunshine today producing a high solar radiation reading of 1,000 watts/m2, there was also a lot of cloud. The barometer reached a high of 1020 hPa mid-day and then began to fall. The forecast is for southeast showers switching back to westerlies tomorrow afternoon.

Only one tour boat was observed in the Ecological Reserve today and although there were dozens of sports-fishing boats all around the reserve none were observed inside.

American Pipits have been spotted bobbing and flitting around Great Race and there is a photo below as evidence. Thanks go out to Rocky Point Bird Observatory for the identification confirmation.

Six Northern Elephant Seals came ashore at first light and spent the whole day sleeping in the garden. One was a tagged, with a pale green tag #5850. This same individual had two tags when I first saw it last fall, October 14.

The Canada Geese are in over-drive right now and uber-territorial. One pair tried again to take up residence in the entrance way to the de-salinator room which is just not going to work.

The Glaucous-winged Gulls are engaging in more definite pairing behaviours and also becoming more territorial. Many are nest building, pulling out chunks of grass turf for padding. Black Oystercatchers are looking broody too and I observed Black Oystercatchers eating limpets today.

 

There were no visitors today.

 

Feb 26, derrick, Yellow tag 5086

Posted on by

Wind E 10 increasing to 20 N. Cloudy, rain in evening. DND blasting continued.

Courtney came out in the morning and brought Kim.  We worked most of the day on setting up the rest of the scaffolding, fixing the derrick cable, and taking down the scaffolding.  Had the new wire rope installed and working by afternoon.  Worked on fire wood and replaced (new) leaky pvc valve in desal with a brass one.

I was finally able to get a clear view of the female elephant seals yellow flipper tag, # 5086. Yellow tags indicate that this elephant seal comes from San Miguel Island or Santa Rosa Island.  We have had several previous sightings of an eseal with a 5086 tag, including this sighting by Julie https://www.racerocks.ca/2012/07/07/new-and-old-faces/ but they were always green tags and this one is clearly yellow.  At some point the pup’s body got flipped over and it is now possible to determine that it is male.

 

The Sun is Shining

There was a light breeze today, not getting higher than 5 knots. The barometer rose throughout the day. The clouds parted mid morning to produce a gloriously sunny rest of the day. The high this afternoon was 13.2 C.

Before Anne finished off her shift, she showed me how to perform a few more maintenance tasks: operate the boat winch, run the washing machine with rainwater, test water salinity and measure the fuel levels in the tanks.

Anne spotted a new tag on an elephant seal. The elephant seal that she mentioned in Wednesday’s log with the tag 7625, has a tag on his other flipper with the number 7688.

One recreational fishing boat passed by the jetty this morning. There were two whale watching boats noticed going through the reserve this afternoon.

There were at least two flashes of lightning seen in the west and loud claps of thunder at 19:00.

Mystery Gull and Monster Mosh Pit

The day started with light westerly winds that brought quite a bit of sunshine. Although the wind picked up a little, today’s weather and sea conditions seemed like a bit of a reprieve after the last week of big swells and high winds. The barometer rose all day but it looks like another southeaster coming tomorrow.

Four whale watching boats were observed in the Ecological Reserve today. There was one sports fishing boat fishing in the Ecological Reserve just before sunset.

I spotted a gull that was a total mystery. I have the question out for help in identification. Do you know what it is? An albino Thayer’s Gull? (This just in: Dick Cannings says that it is a very light, second year, Glaucous-winged Gull.) Sorry no mystery for Halloween.

Mystery gull visited Race Rocks. Jury still out on its identification.

The Northern Elephant Seals continue to occupy the ramp from the jetty. This little guy has tag # 7625 and was tagged as a weanling at Ano Nuevo Island in 2013. So he will turn two this winter.

The sealion count is up dramatically from last week with 980 individuals, 447 Stellers and 433 Californians. It took me so long to count them that I am going to have to finish the census tomorrow and that will give me a chance to recount, if I start earlier. It is a bit like trying to count people in a mosh pit. The photos really help fine tune the numbers.

These sealions are keeping each other warm and catching up on their sleep.

There were quite a few visitors today including two veterinarians Martin and Joe who are part of a collaborative, international team that is (amongst other things) disentangling sealions.  They completed reconnaissance for a possible rescue here. If you have been following the blog you will know that there are at least six ring-necked sealions here with plastic strapping and three more with fishing gear. Entanglement is definitely a human caused issue, hard to deny that one. Both Garry the Ecological Reserve Warden and Chris head of operations at Pearson College were here as well as my colleague Courtney, a contractor and two former students.

My tasks today were focused on cleanup (some of the outside windows on the guardian house), the bathroom, the basement and on sorting and cataloguing images. If someone had told me how time consuming that job is, I wouldn’t have taken so many photos.
