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.

 

Dramatic Weather

Strong west-southwest winds blew all day with a continuous cycle of showers and dramatic clouds scudding through. Wind velocities ranged from 10 to over 30 knots, up the tower. A low snowline could be seen in the Olympic Mountains from time to time and the air was chilly. The barometer has been climbing steadily since last night and the forecast is for more of the same with a risk of thunderstorms.

No tour boats or fishers were observed in the Ecological Reserve and Rockfish Conservation Area today.

A Sea Otter was spotted in the main channel in front of the eco-guardians’ house again today. As the tide turned, it swam over to Turbine Rock and on arrival was surrounded by six or seven small Harbour Seals. The adult seals remained uninterested, asleep on the rock. Through the spotting scope, it looked like interspecies play with lots of exaggerated diving and washing up onto the rock and back out. This is one of the first times I have looked at a sea otter for any length of time when it was not eating, grooming or sleeping.

Three Northern Elephant Seals moved right up onto Great Race today. When I did the water sample at six there was one individual lolling around by the jetty. I looked up mid-morning and three of them were doing the wave along the walkway. One stopped at the intersection, one went back closer to the boat shed and the third went right around the science house onto the rocks on the west side.  None of these individuals were tagged. Once settled, they slept soundly for the rest of the day.

Most of the Canada Geese are sitting on eggs already and the ganders are fearless defenders. I am trying to discourage one insistent pair of geese that haven’t laid yet (I think) from nesting right beside the path to the Energy Building but it seems to be a losing battle.  The area near the stone burial cairns has been seriously overgrazed by the geese and the earth around the biggest one is eroding around the edges. In that area the goose exclusion cages show up a large difference between grazed and un-grazed (caged). In other areas where crab-grass dominates there is little difference inside and out of the cages.

Dawn broke in reds and pinks heralding another glorious day. Early on there were feeble zephyrs from the southwest and east but the most obvious wind tell-tale on Race Rocks, the Canadian flag, hung limply most of the morning. Westerly breezes started in the early afternoon and developed into moderate breezes, late afternoon with gusts to 23 knots. The strong wind warning forecast is downgraded now to 15 to 20 knots westerly, overnight in the central Straits of Juan de Fuca and it is already dropping, as the sun sets.

No tour boats were observed in the Ecological Reserve although one hardtop sport-fishing boat cruised past the sea lions at a respectful distance and speed.

A Northern Elephant Seal visited the marine railway for a snooze on the falling tide this morning. It was a perfectly symmetrical ellipsoid. From the light tower another 16 elephant seals could be seen on Middle Rock. Two more in the shallows of Middle Rock, looked so much like smooth rocks draped in seaweed, that they had me fooled for a while. That makes 19 in total, a high count for me so far.

There have also been a lot of Bald Eagles present with a total of twelve individuals today. I have been trying to figure out what they are eating and have seen them chasing both gulls and geese.

I have also seen some casualties, including three gull carcasses but they do not have the look of eagle food. The one in the photo above is completely pristine even after several days, with no trace of blood or predation.

This evening the eagles caught and ate something but I could not tell what it was, there were no feathers at the site where they were dining but it may have been turned inside out (skinned). Four adults and two sub-adults fed off the one carcass.

Alex continues to be my only visitor and we had a belated Easter dinner, highlighting delicious, fresh halibut. I wonder when the last time was, this kitchen had freshly jigged halibut? Alex resurrected a bench that was both broken and had missing parts. It now sits in front of the Science House with a view out to sea and east up the Strait.

The phone and Internet went off again last night and I didn’t realize it until late. The problem was different this time and required a UPS reset in the tower this morning. I am getting quite adept at restarting the weather system now and we also tried (again) to fix the wind direction indicator on the system. I had success getting the underwater camera going again but it really needs a good scrub. The desalinator filled up the water tank again, running on sunlight through the solar panels. I cleaned up the visitor sign-in cabinet a little and put in some fresh pamphlets about how the public can support Race Rocks through Pearson College.

Note this blog posted next day due to yet another failure of phone/Internet last night due to UPS overload in tower.

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.

Census results:
Steller Sea Lion: 59
California Sea Lion: 62

Sunny
Wind: 0-13 knots SW in the morning, NE from mid morning to afternoon and SW in the evening
Air Temperature: Low 9.9°C, High 13.2°C
Ocean Temperature: 9.0°C

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
California Sea Lion: 43
Harbour Seal: 52

Cloudy, with fog in the morning
Wind: 0 – 16 knots from the W then NE in the morning, switching to SE in the afternoon
Air Temperature: High 10°C, Low 7°C
Ocean Temperature: 8.9°C

This morning, the Pearson students here for Project Week helped stack firewood in the cupboards outside of the Engine Building.

Four oregon juncos and a robin were seen flying around the southern part of Great Race.

This afternoon, four students took part in rescue diving scenarios with Chris. Afterwards a few of them went snorkelling around the jetty to check out the sea stars, a sea slug and other species.

Chunk continues to hang out near the Marine Science Centre.

Three ecotour boats came into the ecological reserve to share the sights, sounds and smells of the marine mammals and birds with their customers.

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.

Dec 28, Warden’s Report -Race Rocks Ecological Reserve

I went to Race Rocks today with Val George for the Christmas bird Count.  ( See other reports from  today.) The highlight of course was the discovery of the first record for the Boreal Owl in Southern Vancouver Island . Some other observations from my visit are included here:

2014-12-28gooseexclosure2 2014-12-28gooseexclosure1m
Several 1 metre exclosures for goose grazing have been installed on the grass  areas on Race Rocks. Winter grazing by the Canada geese (introduced to Vancouver Island in the 1980s) has resulted in erosion in some areas of the island, and grass turf cover is prevented.
2014-12-28macrocystislongm 2014-12-28 macrocystis
Drift Macrocystis at the jetty. This Giant Kelp can grow anchored at great depths but winter storms will lift it up and the  main contribution to energy-flow  in the ecosystem comes from decomposition on the shoreline. Macrocystis grows in areas of high salinity, so not in he brackish estuarine conditions of the Strait of Juan de Fuca , but not at Race Rocks  where it ends up only as drift in the strand line.

This year, the college has finished tilting the solar panels. Increased energy efficiency has been noted. They were originally installed flat since we were concerned that the strength of the wind may damage them. This hasn’t happened. View of the energy building roof from the top of the tower.

This fall a plaque has been installed to honour Johan Ashuvud, who as a student at Pearson College, was instrumental in having Race Rocks designated as an ecological reserve in 1980 ..
