Beautiful Fall Sunset, Minke Whales!

Posted on by

Weather Today: 

  • Visibility 15+ NM
  • Sky overcast, some sunshine in the afternoon
  • Wind 0-5 knots NE
  • Sea state calm, some interesting wave patterns due to currents in the mid day

Visitors: 

  • Greg visited with a contractor yesterday along with some island supplies
  • Not too many visitors in the reserve this time of year. A steady trickle of eco-tourism boats on the less windy days, maybe 5-10.
  • Yesterday we watched the HMCS Brandon leave from its home port, Esquimalt. An impressive vessel in capabilities and design, you can learn more about it Here if you are interested!

Ecological Notes: 

  • On Tuesday we were lucky to be present for a spectacular display of orcas in the strait, roughly 2 NM to the S of Great Race Rock. The pod seemed to be hunting something, perhaps a sea lion. It was an incredible sight to observe, with the whales flying out of the water and slapping the surface with their tales.
  • We continue to see humpback whales daily, surrounding the rocks here and a bit further into the strait. Most of the time we first notice the cloud of water that forms when they surface, exhale, inhale, and dive.
  • Today we were joined by a small group of whales, smaller than humpbacks and not orcas (small dorsal fins). We are thinking that these could have been minke whales since they seemed larger than porpoises.
  • Yesterday evening we found an adult glaucous-winged gull sitting in the intertidal near our jetty. It wasn’t moving and seemed to be positioned in an uncharacteristic way, with wings splayed. We weren’t able to identify any physical injuries, although noted that it wasn’t able to make any normal seagull noises, and seemed to be attempting to regurgitate something. We were hopeful that we might be able to transport it to the nearby wild arc rescue center nearby, but unfortunately it was deceased by this morning. We are wondering if it could have swallowed a piece of human trash that may have become lodged, although we were not able to see anything when we examined it.
  • The sea lions are noisier than ever but seem to have found their places among the rocky intertidal. It is amazing to watch them fish in the early mornings, often surfacing with large salmon with a flock of seagulls close behind! I (Mara) noticed two young tagged sea lions this week that seem to be staying close to each other throughout their time here. It’s hard to say if this happens more often since it’s tough to identify individual animals among the over 1000 currently here!

Additional Notes: 

  • There has been quite a bit of blasting on the DND land over the past week to two weeks. Most of the time it is not unreasonably disruptive, but when there is a particularly large blast all of the animals on the island rush in the opposite direction.

Drizzle, Fog and Steaming Sea Lions

Posted on by

It was a wet, drizzly, foggy day at Race Rocks but very calm. For most of the morning, the wind varied little from  east northeast at less than 5 knots. It only picked up to 10 – 15 knots as it swung around to north northeast in the evening. The forecast for Thursday is similar and while winds are expected to rise to 25- 35 knots southeast on Friday. Periods of rain, cloud and showers are on the horizon in spite of the barometer rising (overall trend) since late Monday.

It was a quiet day on the vessel observation front and only three whale watching vessels were noted in reserve. One ‘sports’ fishing vessel came through at very low speed, well positioned away from the animals.

There was some cetacean activity noted during the day as visibility increased to over 5 nautical miles. This included two Humpback Whales feeding near Rosedale Reef just outside reserve to the south, a Minke Whale just east of North Rock and Dall’s Porpoise to the southwest.

On Great Race, the Sea Lions were steaming today as air temperature hovered around 12 degrees C. and the cooling rain was evaporated off. Part of their haul-out at this time of year is a physiological need to warm their skin during the moulting process, thus the tidy rows of animals pressed against each other and the piling on top of each other to share their body heat. Some California Sea Lions have taken to rock climbing these last few days. They are well established above the boathouse now and at the base of the cliff under camera 5, so the logical (to them) extension was to move further up and there were three of them up by the helicopter pad today. I suspect that they will really like the heli-pad, if they make it that far.

There were six Northern Elephant Seals hanging out in the water around the jetty today.

Adult Glaucous-winged Gulls and this years young, continue to frequent their nesting territories much to my surprise. I have seen them chase off Thayers Gulls. The “visiting” gulls roost in peripheral areas away from the nest sites. A family of four Canada Geese continue to make the island their home.

Chores were as usual and there were no visitors.

Noticeably Darker Day

Posted on by

Today was more of a fall day with cooler temperatures and a threat of rain in the air. Light levels were way down too. The barometer rose to 1014 hPA from a low of 1010 yesterday and it has just started to fall again. Rain and east winds of up to 25 knots are predicted to bring tomorrow’s forecasted rain, with a cool, wet outlook for the week ahead.

Thirteen visits to the protected area, by whale watching vessels, were observed today. Only one pleasure craft was noted.

There was a lot of cetacean action in and around Race Rocks for most of the day. It started with two big, bull, Biggs Killer Whales (Transients), travelling in from the west on the Rosedale side. They were later spotted in Race Passage and not long after an adult female Killer Whale was seen well inside the reserve by Turbine Rock. There were two Humpback Whales, one feeding just east of Race Rocks that moved west through Race Passage. It had a definite white splotch on the right fluke. The other one was feeding just west and had dark flukes, the same one, I think, that has been around for a while. There was also a Minke Whale feeding just to the south of Race Rocks.

Accumulated solar radiation levels today were less than half of what they have been for the last few days, 150 versus 300 to 350 Langleys and the days are getting noticeably shorter, faster now. Migrant species are moving through the reserve daily with hundreds of Surf Scoters moving through from west to east every day. All three species of cormorants are using the rocks here as roosts now and feeding in the multi-species flocks that surround the reserve with much commotion. This change into autumn not only impacts the biodiversity of the reserve but also has an impact on practical things like power generation.

Solar power has been producing over 90% of the power needed to run everything on the island and that amount will change over the next few months. Right now the shortfall is made up with a diesel generator but the plan is to move to cleaner burning propane in the near future. A great deal of progress has been made in reducing the amount of fuel stored and used here, from the days of the Coast Guard when there were six giant diesel tanks dominated the rock and the generators ran 24/7. A big shout goes out to Pearson College, for both reducing the ecological footprint in terms of CO2 and for reducing the risk of a spill.

Sunrise saw the big moon ‘dropping’ in the west this morning and clear sunny skies reigned supreme all day. The falling barometer continued its descent today but the forecast looks good with today’s light easterly winds continuing tomorrow.

Fifteen whale watching vessel visits to the protected area, were observed today. Speed on arrival and departure continues to be an issue with a few operators however the large majority of operators are driving at a slow, respectful and careful speed. A couple of the larger vessels with shallow draught are acting more and more as though they are little speed boats weaving in and out of the rocky islets, in areas which are, by agreement with the industry, off-limits. The agreement was established by consensus, to ensure sustainable whale watching operations within the protected area. Just in case institutional (or other) memory has been lost: travel is supposed to be confined to Middle Channel, going with the current. All of the companies using the Ecological Reserve for profit should be thinking about the example they are setting for pleasure craft and the sustainability image of their company (not to mention their marine insurers who would probably not be too happy about the risks being taken by the few).

Minke, Humpback and Biggs Killer Whales brought the whale watchers to the area today and the seals, sea lions and sea otter brought them into the Ecological Reserve. At low tide the sea otter can be seen in the kelp bed on the southeast corner of the reserve but I am not sure where he goes at high tide. He has moved back there after merciless whale watching traffic as close as was physically possible. While it did not appear to ‘bother” him having large powered vessels lurching over him, decks crowded with people gawking and taking photos, I can certainly understand the move.  The Bigg’s Killer Whales travelled west past Race Rocks today again using the shallow Eemdyk Passage behind Bentinck Island, which is directly across Race Passage from Race Rocks. Quite a few Harbour Seals haul out in there. There was a Humpback Whale feeding next to Church Rock in the morning and a Minke Whale travelling to the east was observed just east of North Rocks. There were Southern Resident Killer Whales in the area according to the VHF radio but I did not have a chance to spot them.

I did have the opportunity to observe some Stellers Sea Lions and take a few photos of two younger ones playing together and an older “couple” that seemed quite wise. I know that may sound anthropomorphic but what I observed was the animal on the left licking the neck of the big old bull and then the two muzzling each other gently lip to lip. It was the gaze of the big old male that seemed to tell a story about a long life. I can’t really explain it so here is a quote from Carl Safina who is very articulate about animal’s inner lives.

“We have no trouble saying that an animal who’s vigorously eating is hungry, and one resting after exertion is tired; yet we can hardly force ourselves to acknowledge that when they’re playing they’re having fun, or that when they’re acting affectionate they’re feeling the bond,” Safina said. “Why? Because denying them all experience reinforces our favorite story: that we are so very special.”

On the sustainability front, today was a great day for solar power and I made lots of fresh water with solar power using the desalinator. Chores were routine and there were no visitors.

 

Traffic Congestion at Race Rocks?

Posted on by

Clear skies and light winds made for a beautiful day. The wind switched around in direction going from east northeast to southeast to west and back to easterlies. Solar radiation was high at 400 Langleys and barometric pressure rose for most of the day going over 1021 hPa mid-day before dropping in the late afternoon and evening. The forecast is for more of the same; sunshine and light easterly winds until Wednesday.

There were a lot of whale watching vessels in the area today and 16 visits by commercial operators were noted in the protected area. Except for a hectic time when killer whales were passing by, most operators were careful and slow. Again a couple of the largest vessels were travelling through shallow areas , close to haul-outs and lacking room for maneuverability: areas where they should not be travelling both for conservation and for safety. Two other whale-watching vessels were speeding in reserve, apparently anxious to get back out with the killer whales or back to base. The big noisy vessel that usually speeds in and out of the protected area was very well behaved today, nice change not speeding. Five ‘pleasure’ craft were observed in the protected area. Except for a fast entry by one boat, they were all travelling slowly and respectfully, including a Pedder Bay rental boat that did a nice drift through Middle Channel while the whale watching zoo was happening in the protected area.

I continue to spot the same branded California Sea Lions, left side brands 5477, 8101, 8228, 6153, 650U and rump brands U391, U105, U601, U321, U255, U148, U118, U174, U894, U239, U223 and more. There are others as well, all photo-documented, as are the Stellers Sea Lion brands. The Northern Elephant Seals left Great Race either early this morning or last night so just the sea lions were here today in the pinniped department. There was one Humpback Whale to the south of the protected area today and a Minke Whale about two miles west. Three Transient (Biggs) Killer Whales (one male, one female and one young) passed close to Rosedale Reef, just to the south of Race Rocks, heading west.

Routine chores were much more satisfactory today with a feeling of progress being made. There were no visitors.

Minke whales are being seen more frequently in recent years off Race Rocks .  See the posts on Minke whales sighted from the Ecological Reserve.
(We are still waiting for a picture of whales in the Ecological Reserve.)

For reporting Minke whales, go to  the Northeast Pacific minke whale project.

The BC Cetacean Sightings Network has a good description and images:

Marine Mammal Hotspot.

Posted on by

As predicted, the west-southwest winds continued today with velocities of 15 – 20 knots. The first half of the day was cloudy and fog threatened but the sun eventually prevailed. Because of the late start, accumulated daily solar radiation was only half of yesterday’s value.

The barometer hovered between 1013 and 1024 hPa, rising in the morning and falling again, in the afternoon. The forecast is for more of the same with the addition of a 30% chance of showers tomorrow.

There were at least 15 visits to the Ecological Reserve by whale watching boats today and probably more as I wasn’t looking every second. Two sports fishing boats sped through the Reserve while most of the whale watching boats followed the rules, slowing on approach and in Reserve, steering well clear of marine mammals, using the middle of Middle Channel, and drifting with the current, or at least going with it.

The reason for all of the whale watching activity was of course biological activity in the area. Race Rocks and environs was a marine mammal hotspot today with at least seven species. At one point there was a Minke Whale very close to the Ecological Reserve boundary just to the east of Great Race and at the same time a large, adult Humpback could be seen ~ 1 nm south of Rosedale Reef travelling east. Once when I looked out at Humpback, it had six vessels pacing it.

Next on the horizon, there were two groups of Killer Whales, both apparently Biggs or Transient (aka mammal eating) Killer Whales. One group appeared to be made up of ~ 3 adult males and the other group looked like females, calves and one smaller bull. The last mentioned group shot out on the ebb tide to the west through Race Passage with a trail of whale watching boats trying to keep up.

Floyd may look like a large lump but when I saw him being frisky today I was amazed at how fast he could hustle that bulk across the lawn after a female.

TEMPERATURE: Max. 14.1 ºC »» Min. 9.6 ºC »» Reset 14.0 ºC
MARINE LIFE: The chatter on the marine radio reported sightings of some Minke whales and also a Humpback but not unfortunately close to us. We did see several Orca a mile or so beyond the MPA boundries.This morning we counted 172 California, 9 Northern Sea lions hauled out on West, Middle and North Rocks. The group hauled out at the dock and along the north shoreline of Gr. Race still numbers 13-15 California and 2 Northern.Most of the day they spend sleeping but through the night get quite vocal. Most of the young gulls have stopped returning to the nest areas and are usually chased off by the adults.
HUMAN INTERACTION: There were 37 Ecotour boats, 2 Charter dive boats and 7 pleasure craft through the reserve today.Station boat to Pedder Bay and back this morning.

Good evening
WEATHER: Max. 10.7ºC — Min 7.5ºC — Reset 8.1ºC Rain 0.4 mm Wind was light and variable. It was a great day to be on the rock.
Although the sea was fairly calm, the 4-6′ swells coming in from the west and piling up to 10-12′ green and white frothy curls on the underwater reefs made for great wave watching!
MARINE LIFE: The birds continue to feed in in large numbers but impossible to count because of the glare on the sea.It was also impossible to positively identify a whale that looked like a 18-20′ Minke Whale even with the telescope, because of the glare and distance.2 of the 4 Northern Elephant Seals regularly hauling out in various areas of Gr. Race spent several hours on the boat ramp enjoying the sun.
HUMAN INTERACTION: There were 5 tour boats and one pleasure craft (4 metre sailboat) in the M.P.A. today.posted by Carol or Mike S at 7:20 PM
