Flocks on the rocks

Flocks on the rocks: Thayer’s gulls and some double crested , Brandts and Pelagic Cormorants. Note orientation into the direction of the wind.

Ecological Happenings

  • Storm force winds in the morning with large swell from the North East leading to high seas and larges breakers on the rocks. Periods of (horizontal) rain with winds dropping later in the day.
  • Four elephant seals on the island now. The new arrival is much smaller than the female and thought to be a juvenile/subadult. There also seems to be a bond between the smaller Elephant seal and female. Could this be Squall, born here in 2012? Checks are being made to see if identifying features match.
  • Birds grouped together in flocks on the rocks while most of the sea lions stayed off the land.

Marine Vessels

  • Coastguard helicopter overhead.

Maintenance

  • Electrical outlet in main residence fixed.
  • Battery health test carried out with individual readings taken on each of the 96 cells.
  • Pressure washer pump stripped back down and soaked in cleaner. To be reassembled.

Weather

Mostly foggy today. Winds below 6kts, though picked up to 12kts by 20:00, in varying directions, with a couple of hours of calm in the early afternoon. Barometer reading was mostly consistent at 102.0. A strong wind warning is in effect for tonight and tomorrow.

Boat activity

  • 6 tour boats
  • 1 pleasure vessel

Maintenance

  • Electric fence repairs on the south side of the island. The fence was also extended as sea lions, are creeping further up onto fresh clean grass.
  • Old water pump was removed in the student house, and the new pump will be installed tomorrow.

No visitors today.

Floyd and Chunk Throwing Their Weight Around.

Posted on by

It was a limpid June day with very little wind and a sultry, summer feel. The solar radiation highpoint of the day was over 1000 Watts per meter2 and this is higher than it has been all week. Around noon the wind changed direction moving about 180o from what it has been for months. It didn’t really do much other than change direction, which was in itself rather remarkable due to the longevity of the westerlies. Maybe now that the interior is heating up so much that it actually catching on fire, it is time for the outflow winds. By late after noon the wind was backing towards south. A cloud formed and dissipated, although bigger cloud formations are building along the Olympic and Cascade Mountains. Although the barometer has been dropping for > 24 hours, it is still high, at 1016 hPA. and the forecast is for clear skies, sunshine and strong westerly winds. By the time the sun set, the wind had returned to westerly 10 to 15 knots.

It was busy on the water here; with 25 whale-watching boat visits, observed within the Ecological Reserve. Some vessels made multiple trips back to Victoria and out again, the last one leaving Race Rocks at 21:20.  At times during the day, there were 5 to 10 vessels in reserve at the same time.

Most of the operators were awesome (as usual) but a few were obviously not aware of the Pacific Whale Watching Association’ Race Rocks Special Operating Area Guidelines and the Department of Fisheries and Oceans Marine Mammal Regulations. The latter can carry a powerful punch. Speed is an issue, so is distance and route is another. At one point today I was concerned about the risk of collision and passenger safety but they are all used to dancing around each other and my worries may have been unwarranted. It would certainly have been difficult for any marine mammal in the water with all of those vessels plus the current to contend with.

The PWWA guidelines say that while vessels are in the Race Rocks go-slow zone, they will transit the area with the current and will remain as close to mid-channel as is possible between major rock outcroppings known as Great Race (with the lighthouse), North Race Rock, West Race Rocks and Helicopter Rock. Some operators think it okay to squeeze in between Great Race and South Islands and there is just not enough room in there even for the smaller zodiacs, especially if they are scaring animals into the water at the same time. This is a professional development opportunity for the industry. I fyou are an owner or manager, please set clear operation standards for the Race Rocks Special Operating Area. Rise above the low bar of guidelines and regulations. Educate the public by doing the right thing and demonstrate support your operators to get on side, for the business of summer is about to descend upon us.

A coast guard rigid hull inflatable hailed me when I was out on the jetty today. They were on patrol from the CCGS M. Charles M.B., which was anchored nearby. They offered support on the enforcement side for the Race Rocks Rockfish Conservation Area and said that part of why they were here was to deter marine mammal harassment. The vessel is named after a famous life-saving, west coast chief, the late Martin Charles Hereditary Chief of the Dididaht and long-time Bamfield Coast Guard hero. He was a great man and it is very good to see a Coast Guard vessel named after him.

There were only four Northern Elephant Seals on Great Race today and Middle Rock only had two. On Great Race it was Floyd, Chunk, an untagged female nicknamed Grace and the tagged female 5866. Chunk threw his weight around during the Floyd and Chunk show today and after a big, half body neck press by Chunk, Floyd fled, his usual fate. Later Floyd did the same thing to Grace, only he had her by the neck with his teeth and she is only a fraction his size. She managed to wriggle away in the water.

There was serious whale action in the area but not right in the Ecological Reserve today.

I ran the fire pump today and pumped seawater into the cistern. The transformation of saltwater into freshwater by desalination, running off solar power, is really sweet. It makes me very aware of and thankful for fresh water consumption.

Most chores were routine and there were no visitors today.

 

Double-Billing (Thursday-Friday)

Posted on by

Thursday was a howler. The wind started early and blew ferociously all day. Although it developed into a classic westerly, it actually started out from the west-northwest, which is closer to the direction running down the outside coast of Vancouver Island (NW). Most of the day, it was westerly from 30 – 40 knots and late in the afternoon there gusts over 40 knots. The fog that formed early on the Port Angeles side of the Strait was blown away early and the sky stayed clear until just after sunset when clouds became visible in the west. The barometer has been rising since Wednesday and the forecast is for continued gale warnings and mix of sun and cloud.

 

It really calmed down on Friday. The westerlies with a touch of southwest, continued but at moderate speeds of 15 -25 knots. Although there were clouds to the west early in the morning, they evaporated quickly and it was full on sunshine all day. The barometer is dropping from a high of 1020 hPa and the forecast is for strong winds and mostly clear skies.

There were no whale-watching boats, or sport fishers on Thursday, as the weather and sea conditions were just too wild. Friday was a totally different story with 16 whale-watching vessels observed, visiting the Ecological Reserve. Some vessels made multiple visits.

There was a lot of whale activity within and around the Ecological Reserve. Both a Minke Whale and a large Humpback were feeding just to the southeast and south respectively and three different pods of Killer Whales moved through the area in the afternoon and evening, including small group of Bigg’s Killer Whales (Transients), two pods of southern residents ( J-pod and L-pod according to the whale-watching boats). One of the SRKW pods came right into the Reserve within fifty meters of South Rock, heading east. There were two large adult males, one small calf and about 15 individuals all together. Another ~ 20 individuals were travelling in the same direction about one mile to south, at the same time. It appeared as though the two groups met up and mingled to the east of Race Rocks. Time for the sockeye to be running.

Other ecological happenings are progressing as has been reported on for the past few weeks. I started a Glaucous-winged Gull nest survey Thursday and finished surveying about one third of the island. On Friday the female Northern Elephant Seal # 5866’s tags were noted. Chunk and Floyd have been peacefully moulting, sleeping and travelling up and down the ramp for several swims a day (more like lolly-gagging in the water).

Thursdays are animal census day. It is worth noting that the winter resident bird species such as Black Turnstone, Harlequin Duck and many species of gulls that nest elsewhere are gone now and so are the transitory migrant shorebirds and other migrants that stop off briefly or for a while. The sealions are at their lowest number which is expected since they too should be on or heading towards their breeding grounds. Census results follow.

Glaucous-winged Gulls total 424 (402 adults in nesting areas; 22 sub-adults in roosting/resting area). Most gulls are incubating now, although some are still getting started.

There were no visitors on Thursday and two visitors Friday, who did a retreat in the science house. They came and went in Second Nature with Chris.

Chores and maintenance were routine today and I am glad to report that I am able to wash windows again.

 

Chunk ‘nd the Trunk

Posted on by

It was a glorious day at Race Rocks with westerly winds continuing from yesterday but with more moderate speeds of 15 – 25 knots and even lighter winds of 10 – 15 early in the morning. The sky was clear above although there was a ‘marine haze’, which reduced visibility early to less than ten nautical miles. As the winds picked up so did air quality leading one to wonder if the ‘marine air’ actually has an onshore and anthropogenic source.  Solar radiation intensity was high today peaking at over 900 W/m2. It is 19:00 hours as I write this, with more sunshine to come and the accumulated solar radiation for the day is already close to 700 Langleys. The forecast includes a westerly gale warning for tomorrow afternoon and evening with clear skies and a high UV index of seven.

Only one whale watching boat (from Sooke) was observed in the Ecological Reserve today.

There were more large and startling (at least to me)  explosions today, which did not result in even a visible flinch by the Northern Elephant Seals. The Harbour Seals got into the water and were looking around at the surface and the Pigeon Guillemots flew but quickly returned and recovered. Two vessels with containment booms, one travelling at a fairly urgent-looking speed towing some of the booms were observed in the vicinity of Race Passage today. It may have just been an exercise, as they didn’t stay long.

Ecologically, things are continuing to grow at a tremendous rate as spring accelerates for the shift into summer, in less than two weeks. The goslings have graduated from short paddles to longer endurance swims crossing Middle Channel. Their grazing pressure on the island continues but doesn’t seem to exceed the productivity of the grasses that they graze on.

In the water, the productivity of Bull Kelp or Nereocystis lutkeana continues unabated and large, well formed kelp beds fringe all of the islets and reefs, producing tremendous amounts of food for a broad array of direct grazers and both peripheral and out-lying detritovores that eat the sloughing bits and pieces that drift down from the canopy and out of the kelp beds.

We are supposed to stay on the walkways when moving around the island. Not always possible when there are traffic jams like this one in this morning's commute.

The Northern Elephant Seals spend time in the water draped in the kelp and playing with it with their mouths. What is not clear is whether this is intentional or just there (in the way). The big males are taking several swims a day right now thanks to the marine railway, which makes access so much easier for them. Chunk’s moult is just visibly starting today, on his nose and just below his mouth and on what would be a chin if he had one. Floyd’s moult is progressing visibly as wound sites and patches where he can scratch are coming off. There were some interactions between the two big guys today but hostilities were averted through strategic maneuvering by Floyd, basically avoidance behavior. Above, he is making a slow get-away which of course requires a tremendous amount of energy and much resting.

More gulls are sitting on eggs each day and their nests are beautifully made by pulling up grass by the roots and carefully packing it into just the right shape by pushing down with their sternums, tails in the air. Level is of course important. All of the nests observed today had three eggs.

 

There were no visitors today and chores were routine.

Chunk Came Back.

Not surprisingly it was another day of westerly winds ranging from 15 to 20 knots. There was also thick fog almost all day, with only a few minutes here and there, with good visibility. The barometer didn’t do much and ended up where it started at ~1015 hPA and the forecast is calling for the usual strong wind warning and fog patches.

Five whale watching vessels were observed in the Ecological Reserve and there could well have been others, but I couldn’t see them due to the thick fog.

The demolition range at Rocky Point was very active today. There were some very large explosions, which when in succession, had the effect of scaring the Stellers Sealions into the water. The Northern Elephant Seals didn’t even flinch and the California Sealions became alert and then went back to sleep after a bit of barking.

Chunk returned to Race Rocks today after an absence. He seems to have itchy flippers.

Chunk came back today. His absence has had me wondering whether he had met his fate in the deep or far offshore. I haven’t seen him since winter/spring 2014 and he is even bigger now. His unmistakable star shaped scar (the chunk that was torn out) is still prominent making identification straightforward.

The interactions between Floyd and Chunk were interesting; Chunk tried to avoid Floyd, at one point rotating 180 degrees on the jetty ramp and then “hustling” up the ramp ahead of Floyd, who was also ascending. Floyd followed and Chunk went all the way around the tank shed and back down the other path to get into the water without an interaction.

Tagged Northern Elephant Seal female #5086 was spotted today. Her tag is getting a little worn, as is her flipper where it rubs. Earlier a male was biting her on the tale hard enough to draw blood.

It was another steady, west by southwest day, blowing 15 to 20 knots, from morning to night and clearing out the clouds for a glorious afternoon and evening. There was just enough marine haze on the horizon to make a great sunset. This morning barometer gradually rose to 1016 hPA and then started a slow decline after noon ending up at 1014hPA just before 8:00 PM. The forecast is calling for strong westerlies to continue with a mix of sun and cloud.

Only four whale watching boats were observed in the Ecological Reserve today and everyone was on their best behaviour.

Ecological happenings were subtle today. More sealions are hauling out on Great Race including a few very chunky Stellers bulls. The California Sealions seem to putting the call out for others within hearing range to come and bark in concert. There are more birds mating wherever you look, the Canada Geese goslings are growing incredibly fast and the bull kelp is now forming a broad canopy even on the high tide. The gull bolus contents are shifting to more ‘forage fish’ bone content from the earlier strong bias toward chiton plates and the adults are feeding each other in practice for parenthood?

The Bald Eagles continue to fly in and scare all the gulls, geese and oystercatchers and it looked like they caught something today, but I am not sure what..

Chris and Courtney brought Second Nature out in the afternoon with two visitors from Scotland, (an alumna and her husband), and the two relief eco-guardians Guy and Christine who will be here for the summer. Chris, Courtney and Guy delivered diesel for the generator, using the derrick, barrels, a drum dolly and a fair bit of sweat. It looked scary to me but they pulled it off with aplomb and Chris said it is easier, safer and less risky than the old method, so that is really great.

My chores today were routine. I am going to post this now and update it with photos later in case the Internet goes down again in between. Must run and shut down the generator.

 

 

Well Timed with the Race

Posted on by

Winds were calmer today and came from the same general direction, ranging from west to southwest, at a respectable 10 to 20 knots for most of the day. The speed picked up at bit in the evening, pushing behind the first Swiftsure sailboat back with 25 to 30 knots. The sky was partially overcast for much of the day but it was bright and sunlight levels were energetic. The barometer continued its climb started late Thursday, peaked late in the afternoon, and started the inevitable slide back down. The forecast is calling for more wind this evening and more of the same tomorrow.

There were a lot of vessels, all around Race Rocks today as the Swiftsure Sailing Race passed by, mid-morning and began returning in the evening. None of the sailboats in the race were observed within the Ecological Reserve although a few were drawn close to North Rocks by the currents. Six whale watching boats were noted working in the Ecological Reserve in the morning and one in the afternoon. The usual Saturday dive charter tended a group of divers off South Islands.

Divers enjoy the incredible biodiversity underwater at Race Rocks. The Ecological Reserve includes the creatures on the bottom, so it is a sustainable diver destination with responsible operators like Ogden Point Diving gate-keeping.

The Northern Elephant Seal moult continues, as does mating, nest building, laying and incubating by Black Oystercatchers. The Pigeon Guillemots and Glaucous-winged Gulls are not far behind and the Canada Geese are way out ahead with some gaggles of goslings already larger than chickens.

This female Northern Elephant Seals contributed a skin sample without knowing it.

Skin samples and vibrissae were collected today, from the ground where moulting animals had been lying. Luckily they leave and go for a swim once and a while, so this is a non-invasive way to take a sample. The hope is that funds for isotopic analyses can be found. Information generated by these analyses will give information about diet and trophic level and could be particularly meaningful for tagged animals, for which there is already baseline data. Some of these animals, such as 5850, also had a satellite tag earlier in its life. There is very little information published on the only Northern Elephant Seal colony in Canada.

A single Brant visited today, stopping off on the helicopter-pad to have a rest and preen. Oddly enough the gulls were not that welcoming. It didn’t stay long enough for the Canada Geese to notice.

There were no visitors today and chores were routine, of the entropy defying type. Solar power was used to run the desalinator and make lots of fresh water today in spite of clouds.

 

 

 

 

Yellow-headed Blackbird

Again it was a day dominated by the west and west-southwest winds. It was blowing 30 to 35 knots at dawn but the velocity subsided and most of the day it blew 20 to 25 knots. Skies were partially overcast and as predicted there were a few showers. Air temperature remains low, and is not much different than flooding sea surface temperature at ~ 9.7 oC. ranging between 10 oC and 12 oC .The wind is also chilling and today had the highest wind speeds of the week. The barometer rose today from 1008 to 1013 hPa and is dropping now while the forecast calls for gales and a gale warning has been issued. Saturday is supposed to be mainly cloudy with a 30% chance of showers.

There were four whale-watching boats observed, working in the Ecological Reserve today. No other vessels were observed in reserve.

Female Northern Elephant Seal # 5086 is on day seven of her moult now and has made great strides in losing skin during the last 24 hours. She has achieved the two thirds moulted milestone and is still grouchy.

Black Oystercatchers are without a doubt nesting now and there are eggs in their terribly spartan nests, which have none of the comforts of home like soft vegetation or down.

Some of the goslings are getting quite large and although they may be considered pesty, they are still fascinating to watch.

The California Sealions are moving back onto Great Race and I awoke to a chorus of them doing a call and response outside my bedroom window this morning.

Thanks go out to Don Stewart for spotting and identifying an Anna’s Hummingbird on Great Race today, I believe this is a new addition to the species list here.

DCS

Another thank you to Rocky Point Bird Observatory for identifying a Yellow-headed Blackbird, another possibly new bird to the island. It has been hiding in the long grass and thistles near the base of the Light Tower and it has been difficult to get a photo fast enough. Today it flew to the roof of the Energy Building which made a photo much easier.
