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.

 

 

 

Shift Switch

The almost constant wind of Race Rocks did not disappoint today. Although is started slowly, once it warmed up there was a steady blow from the west of 25 to 30 knots. The sky was mostly clear with a little fog coming and going late morning and high clouds spreading out from the mountains. The barometer peaked at close to 1019 hPA. and then started to fall in the afternoon. There is a strong wind warning in effect again for tomorrow with the prediction following the pattern of light winds in the morning and building in the afternoon. The last few evenings have been quite windy and rough and the forecast tomorrow has a 40% chance of rain in the late afternoon and evening, on top of the wind.

Two whale-watching boats came through the Ecological Reserve today. A Pedder Bay rental boat was observed fishing for rockfish in Rockfish Conservation Area which is closed to fishing. When I went out to take their photos they tried to move out of sight and ended up fishing about 50 feet off of Middle Rock. When I continued to document their activity they moved out close to the boundary and that is when the Pedder Bay folks showed up to encourage them to move out of the Reserve. That kind of support and community encouragement to follow the rules is really amazing. A big shout out to Pedder Bay Marina, thank you for making the effort for conservation. That kind of response will help keep your business sustainable.

Things continued as expected today with the usual ecological happenings described in the the last few days’ Logs. Chunk and Floyd avoided each other a bit more today which is definitely a good thing for the gulls which don’t stand a chance when the big guys get out of control. Floyd is almost finished his moult with just a few vibrissae and wee scraps of old skin on his back to go. He has lost a tremendous amount of the bulk he brought ashore when he first arrived.

Floyd has lost not only his skin and fur but also ~30% of his weight, since he came ashore to moult.

Floyd has lost not only his skin and fur but also ~30% of his weight, since he came ashore to moult.

Killer Whales were in the vicinity in the early evening. A small pod of Biggs’ Killer Whales swam slowly westward through Race Passage and the whale watching boats were talking about the Southern Resident Killer Whales’ L-pod being a little further west.

There were no visitors and work was focused mainly on preparing and cleaning things for the next crew, Guy and Christine, who will start tomorrow. It has been a real privilege to be out in this special, bio-diverse and productive place and I look forward to returning and meeting the next wave of marine science students in September.

March 20 – Spring Equinox

Overcast with occasional light rain
Wind: NE 6-15 knots
Air Temperature: Low 9.2°C, High 11.2°C
Ocean Temperature: 8.8°C

The Spring Equinox brought more of the same weather. The daffodils, which have been in bloom for about a month, are beginning to die off. The canadian geese and gulls are still spending their days looking for their future nesting sites. They are getting more aggressive with each other. I don’t need an alarm clock in the morning, because the birds wake me up with the sun. The goose droppings are piling up in various deposits around the main island.

Courtney brought out a group on Second Nature from Pearson: Roman, Noemi, Roger, Catherine, Heather and Kim. They will be staying for the weekend and helping with some service projects on Saturday.

March 19 – Last Day of Winter- Census

Raining
Wind: NE 4-14 knots
Air Temperature: Low 8.8°C, High 10.3°C
Ocean Temperature: 8.8°C

The wet conditions were helpful with cleaning some exterior walls and windows. The rain water cistern was filled up from the roof. The rain also helped wash away the algae and slime on the walls, along with some scrubbing.

The low light and rain made the census difficult. In recent days, there has been a much higher number of harbour seals hauled out on the rocks. The sea lions also spent most of the day in the water. It was not possible to distinguish between the species of cormorants on Turbine or Middle Rock.

There were no boats seen in the reserve today.

Three Pearson students came to Race Rocks this morning. Karen, Sunny and Hanne joined Martin, who has been here since Monday.

The students did some work this afternoon: sweeping all 99 steps of the lighthouse and continuing the process of stowing the chopped wood in all the nooks and crannies of the buildings, to be used next winter to heat the main house.

There was DND blasting happening in the morning and early afternoon on Bentinck Island, less than 1km away from the ecological reserve.

Today’s high temperature of 13.2°C, as measured at the ground weather station, was the highest recorded since 2006, when the weather station was installed. A high of 14°C was recorded by the instruments at the top of the lighthouse.

Three eco tour boats visited the reserve. One boat came very close to a group of sea lions swimming and others hauled out on the South Islands.

The low tide of 1.1m at 13:52, exposed lots of species from the low tide zone into the air. The shore and tidal pools were full of life: mussels, barnacles, limpets and lots of other flora and fauna of the sea. The oystercatchers and shore birds were having a feast.

There were no small birds perching birds seen today. There are usually a few fox, sparrows, savannah sparrows and occasionally juncos and robins zipping around the island.

Here are the results from today’s Megafauna Census:
Elephant Seal: 1
Steller Sea Lion: 54

March 6 – Bright Sun, Bright Moon

Mostly sunny
Wind: 3 – 11 knots NE
Air Temperature: High 10°C, Low 7°C
Ocean Temperature: 8.8°C

Last night was a full moon. Tonight’s moonrise happened at 19:25. It’s a waning gibbous moon, but it’s still as bright as last night.

The gulls seem to be getting more territorial by the day. I witnessed many gulls attacking each other throughout the day. One gull grabbed onto another’s wing and wouldn’t let go for a minute. Maybe the other gull got too close to a nesting site that was already claimed.

Chunk, the male elephant seal, spent another day in the same spot below the helicopter pad. The female elephant seal splashed around the jetty beach for most of the day.

One eco tour boat visited the reserve today.

March 5 – Census Thursday

Sunny with occasional clouds
Wind: 0-5 knots from N and switching around to SW throughout the day
Air temperature: High 10C, Low 6C
Ocean temperature: 8.9C

A great blue heron hung out on northeast side of Great Race for the afternoon. The oystercatchers are travelling around in pairs and are quite vocal. The gulls have spread themselves out around the island as they start to find nesting sites. Chunk returned to Great Race during the night. He spent the day resting against a boulder and the rock below the helicopter pad. The female elephant seal is relaxing in the same spots as yesterday, to the west of the main house.

March 2 – Shift Change

Sunny
Wind 5-10 knots S to SW
Low 5oC
High 9oC

Two whale watching boats were seen in the ecological reserve.

Today was the shift change that saw Alex depart after being on for three months and Virginie for a month. It was a calm and glorious day to ferry the supplies and people back and forth to Race Rocks. Thank you Alex for all the great work you have done and the great shape you have left the place. I will be here until the end of March.

Shift Change?

The wind blew from the northeast between 17 and 27 knots. At 15:00, the wind died down a bit, blowing between 12 and 14 knots for several hours. The barometer dropped from 1014 hPa to 1008 hPa. The sky was clear, with some clouds in the south. Whitecaps rolled in from the northeast, calming down in the early afternoon. The temperature reached a high of 6.7oC at 15:00.

There was one whale watching boat seen in the reserve.

The winds, swell and tides combined to allow me to stay another day on the Rock. Between my time mopping the floors and tidying up inside the buildings, I observed sea lions through the binoculars. There were no branded or entangled sea lions observed. They all appear healthy. Many have moved on from Race Rocks, probably to go further up the west coast of Vancouver Island.  It will be interesting to see how many are still here. We will have to wait until tomorrow’s census to find out.
