Six visitors briefly came to the island yesterday morning. Lawrence installed the new deck hatch he made for the station boat. Everyone helped transport and load eight of the old batteries onto the college boat to be taken back to the shore for recycling.

I ran the water pump for five hours to fill up the cistern with cleaner seawater.

Three tour boats were in the ecological reserve yesterday. Today, a dive boat had several divers in the water just north of North Rocks at slack tide in the mid morning.

There was a lot biodiversity in the ecological reserve today. Here are the results from the weekly census:

The numbers of sea lions continues to be low. For the first time this winter, there were more steller than california sea lions in the ecological reserve.

For the past day, the elephant seals have all been stationary. An elephant seal was seen on Middle Rocks today along with california sea lions. I believe it’s the smaller adult male that was on the main island until recently.

Having heard the killdeer on many evenings this winter, but not seen any, I finally saw one this morning on the lawn. They are named for their shrill repetitive call which sounds like “kill-deer!”

Here are the results from the weekly census observed on Friday, February 28:
7 elephant seals (4 adult males, 2 female pups, 1 male pup)
54 steller sea lions
53 california sea lions
86 harbour seals
5 bald eagles (2 adults, 3 juveniles)
26 Canada geese
9 brandt’s cormorants
10 double-crested cormorants
31 pelagic cormorants
72 gulls (mostly thayer’s)
8 black oystercatchers
66 pigeon guillemots
17 harlequin ducks
1 killdeer
15 black turnstones
6 surfbirds

Yesterday, Greg, Alex, Warren and Cole were on the island to do maintenance on the desalinator and batteries. Two tour boats were seen in the ecological reserve each day. This afternoon, the RCM SAR boat from Sooke drove around the main island and the crew took photos.

 

Varied Thrush and River Otter

Wind: yesterday 2-27 knots from NE to W, today 2-27 knots from W to E
Sea State: yesterday rippled in am and calm in pm, today rippled then calm in evening
Visibility: yesterday 10-15 NM, today 5-15 NM
Sky: yesterday clear, today partly cloudy with sunny patches
Temperature: yesterday 4-8 °C, today 6-8 °C
Atmospheric CO2: 414.36 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

A varied thrush was seen on Race Rocks today. The bird that has similarities in size and colouring to an American Robin, hasn’t been seen this winter and possibly never before on Race Rocks. There is no mention of other sightings on this website. According to the Audubon field guide, varied thrushes like dense forests with lots of water. That’s about as different as you can get from Race Rocks, where there are no trees or fresh water. Perhaps this bird was flying over the Strait and stopped for a rest.

There were 20 pigeon guillemots near the jetty yesterday. They swam around, perched on rocks and the edges of the jetty. None were seen today.

The elusive river otter was seen today. It was sunning itself on a log on the rocks below camera 5. When it saw me taking photos from about 30 m away, it went around the corner and continued to soak up the sun.

Over the past few days, I have been trying to tidy up the human items left on the ground, before the grass and other plants grow up around them. There are many old hoses in various places that were at one time used for gardening and washing buildings. I have collected all the old hoses so they don’t interfere with the animals. Black plastic sheets that were used for landscaping at the base of the tower and around the main residence were becoming exposed. I removed all the pieces of plastic that have worked their way to the surface.

There were seven visitors to the island yesterday from Ocean Networks Canada. They spent several hours calibrating the CODAR equipment that measures near-surface ocean currents for the central portion of the Juan de Fuca Strait.

Yesterday, other than the Pearson College boat, Second Nature, there were two tour boats in the ecological reserve. Today, four tour boats, one sailboat and two pleasure boats were around Race Rocks.

Below are the results of the weekly census observed on Saturday, February 22. The numbers are substantially lower for almost every species regularly seen over the winter. Perhaps the relatively clear and calm conditions of this past week have encouraged the birds and marine mammals to venture further from their winter retreat on Race Rocks.

8 steller sea lions
60 california sea lions
30 harbour seals
1 river otter

Yesterday, I used the leaf blower in the boat house to clean out the thousands of dead flies left over from last summer. I laid out 76 m (250′) of fire hose to pump water from the jetty to the cistern. The fire pump ran for a couple hours to top up the seawater cistern used for the desalinator.

For the first time this winter, I saw about 20 pigeon guillemots in the water just north of the jetty yesterday morning. I haven’t seen any since.

There were 3 tour boats in the ecological reserve yesterday and no visitors on the island this weekend.

Yesterday in the morning, three members of the Coast Guard came in a helicopter to do a routine check on some equipment on the island. The pilot phoned ahead to confirm the best place to land to try to avoid disturbing the animals. They landed on the helicopter pad. Sometimes they land on the grass at the base of the lighthouse. The Coast Guard guys were excited to see the elephant seals, which they hadn’t seen before. Usually when they fly into the lightstations up the coast, they see a lot of sea lions.

In the afternoon yesterday, three visitors from Pearson College came to the island to have a tour.

The only other boats that were seen in the ecological reserve were two tour boats this afternoon.

See the photos below for some views from the last two days.

This morning at sunrise, the elephant seals saw their shadows. As the lore goes for their fellow mammal the groundhog, that means six more weeks of winter. Hard to believe with the crocuses blooming and daffodils buds almost ready to burst. Although, there is snow in the forecast for tonight and tomorrow as the temperature drops to 0 °C.

There were no visitors to the island. Two eco tour boats were seen in the reserve this afternoon.

The blasting at nearby Bentinck Island wrapped up this morning, after three days and about 25 blasts. The sea lions left the jetty completely this morning after a few loud blasts. It sounded louder this morning because the northerly wind, coming from the direction of Bentinck Island.

Since the power issues began last week, the Environment Canada weather station at the top of the tower has not been reporting the hourly weather conditions for Race Rocks Lightstation. Replacement communication equipment is being sent out, so hopefully the weather will be recorded again within the next few days.

Two eco tour boats were in the reserve over the past two days. The only visitors to the island were Greg and Alex, a Year 39 Pearson student, who came by yesterday to drop off jerry cans of gas for the back up generator. Alex was reminiscing about visiting Race Rocks and SCUBA diving as a student.

See the photos below for sights from the past two days:

The five day old elephant seal pup died overnight. It was in rough shape yesterday, possibly from attacks by other elephant seals. In the morning yesterday, it had fresh blood on its face and the alpha male was lying on the pup. Ravens and black turnstones have been pecking at the seals face occasionally for the past day.

The first elephant seal pup, which is fending for itself now as a weaner, was lying on its back today and I could tell it was a male. See the photo below. I am not sure the sex of the other pups, as I haven’t had a good look at their abdomens.

There were four visitors to the island yesterday. Jeff brought out Greg, Alex and Ric to work on the power issues. They hooked up a backup generator to help power the island and top up the batteries. In the afternoon, Greg brought a diesel delivery. Now, the island has a full supply of fuel for when the main generator gets fixed within the next few days. In the past few days, there has a been some power generated by solar energy, which has helped keep the batteries charged. Thanks to some IT help from Dan at the college, now there is internet for the weather systems and monitoring the power.

Four eco tour boats were in the reserve over the past two days.

The snow is melting quickly, bringing puddles and mud.

The one day old elephant seal pup appears to be doing well and nursing a lot. It’s moving around and wiggling more than the other two did in their first couple days. The alpha male has been mating numerous times with the mother of the oldest pup.

In the early afternoon, I wandered around the island and peered out from the top of the tower to count the mammals and birds. There were some notable omissions in this fourth week of conducting the census. I didn’t see any geese today. The only sign of the honking birds was a lot of poop and tracks in the snow. I also did not see any black oystercatchers. It is possible the birds were scared off by the loud explosions. The Armed Forces were blasting yesterday and today at the Department of National Defence land-based demolition range on Bentinck Island, the closest land to Race Rocks. Directly after each blast, I witnessed sea lions stampeding into the water and birds taking flight. According to a 2017 article On the firing line with the navy, in the Victoria newspaper Times Colonist, the detonation range is used for training members of the Canadian Navy on how to use explosives. The navy has apparently made efforts to lessen the effects on marine life.

The last two days were spent doing some tasks around the island like running the desalinator, topping up the batteries with the generator and cleaning. Today, the sun in the morning and early afternoon was taken advantage of to get a great view of all the species for the weekly census and do a solar powered load of laundry.

The only visitor was Greg, who came out from the college this afternoon for an hour to show me how to use some equipment and remove a load garbage from the island. No other boats were seen in the ecological reserve.

I am glad to hear the Race Rocks live video cameras are being used by the grade 10 students in the Trek Outdoor Education Program, in Vancouver.
