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
1 fox sparrow

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.

: Killdeer on the grass

: Harlequin ducks on the rocks

: The majority of the sea lions were on the north side of the island

: I found the edge of this poking out of the grass behind the house. I’m not sure what it is. It appears to have lead in and around the rounded part.

: A male elephant seal hauled out with the california sea lions on the Middle Rocks.

: Many of the large puddles on the island are growing algae.

: The waxing crescent moon seen at 17:55, a couple minutes before sunset this evening.

Varied Thrush and River Otter

Posted on Saturday,February 22, 2020 by Nick Townley

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.

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.

: Coast Guard helicopter taking off from the helicopter pad.

: The sleeping california sea lion on the right was damming the water that was draining down the ramp by the boat launch.

: Yesterday, the clouds parted at sunset after a brief blast of wind and rain in the late afternoon.

: Double-crested cormorants drying out their wings

: The elephant seal harem basks in the sun. The pup in the middle is the third pup, a female, which is the last one nursing. In a couple days, the mother will wean the pup and leave the island.

: The first pup lies by himself on the east side of the house. Gulls and sea lions are by the shore in the background

: Black turnstones sleeping in the sun on the rock ledge to the west of the jetty

: I took this photo to make a note of where the alpha male was lying. Later, after he moved to the grass, I measured from the places where his tail flippers and proboscis were. He is 4.4 m long or 14.5′.

: The smallest adult male elephant seal is on the path after coming in from the water. The scars on his back show that he gets in a lot of fights with the other males.

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 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.

First Weekly Census of the Decade

Posted on Friday,January 3, 2020 by Nick Townley

Wind: 5-21 knots N-NE
Sea State: up to 3 m waves
Visibility: 10 NM
Sky: overcast with rain
Temperature:5-11 C
Atmospheric CO2: 412.64 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The weekly census was done today, because the rain yesterday created poor visibility. This morning, it was overcast but not raining, so there was a good birds-eye view from the top of the lighthouse. Some species that were not last week are a whimbrel, snow bunting and another female elephant seal. The new seal looks pregnant, so there might be another pup very soon. She has moved into a spot on the grass between the desalinator building and the flagpole. That’s a great place for me to watch from the house, which is just 20m away. Last year, the three pups were born between January 4 and January 20.

I heard back from a sea lion researcher about the branded sea lions that were seen on Race Rocks a two days ago. Bryan, from the Oregon Department of Fish and Wildlife, let me know about some of the places where the sea lions have been:
California X282: branded at Astoria (Oregon) on Feb 25, 2016 and resighted in Oregon and at San Miguel Island, CA in 2016-2017.
California X392: branded at Astoria on March 8, 2016 and resighted in Oregon and at San Miguel Island in 2016.
California X501: branded at Astoria on May 24, 2016 and resighted in Oregon fall of 2016.
California 1-59: braded at Bonneville Dam (near Portland, Oregon on the Columbia River)on May 19, 2015 and resighted at Astoria and Bonneville through 2017.

The only boats seen in the ecological reserve were two eco tour boats and two kayakers.

Annual Christmas Bird Count

Posted on Saturday,December 28, 2019 by Nick Townley

Wind: Yesterday 5-10 knots W; Today 5-20 knots NE
Sea State: up to 1 m chop
Visibility: 10 NM
Sky: overcast with rain this afternoon
Temperature: 7 C

December 28 is the annual Christmas Bird Count, which happens in thousands of locations across North America. It has been happening for twenty-two years at Race Rocks. This morning with the northeast wind and dropping pressure, the planned visit by the local bird enthusiasts was called off. But fear not, citizen science provailed. For an hour and half this morning, I searched for birds of all feathers as I walked around the island and looked out from the top of the lighthouse. I used binoculars, a spotting scope and the zoom lens on the camera to check out the shoreline, water and the rocky islets of the ecological reserve. I was able to spot 12 species of birds, some of which were not present when I did the weekly census two days ago. Here are the results and photos of the bird count:

25 bald eagles (5 juvenile, 20 adults)
1 fox sparrow
4 canada geese
2 ravens
6 harlequin ducks
208 double-crested cormorants
59 pelagic cormorants
281 thayer’s gulls (on the rocks and in the water)
48 mew gulls (near Turbine Rock and North Rocks)
18 surfbirds
42 black turnstones
4 black oystercatchers

Photos of some of the birds seen today:

: Six of the 25 eagles seen in the reserve this morning

: Bald eagle on the high point of the island near camera 5

: Six harlequin ducks near the southwest corner of the island

: Fox sparrow in the middle of the island

: A colony of Thayer’s gulls on southeast side of the island

: Thayer’s gulls on the southwest corner of the island

: 18 surfbirds near the surge channel just west of the energy building

In the past two days, I have seen two entangled sea lions. Yesterday morning, I noticed a large steller sea lion with a small rope around its neck. The rope appeared to be cutting into the underside of the animal’s neck. A short while later, I noticed a california sea lion with a cut on its neck from what appears to be a plastic strap wrapped around it. The Marine Mammal Rescue Centre and Department of Fisheries and Oceans have been notified. If the sea lions remain at Race Rocks, it might be possible for a rescue to occur. Both animals were seen again today. See the entangled sea lion and marine mammal rescue tags for past occurrences that were written about in the Log. Two other california sea lions were seen that appear to have healing wounds from something that was previously wrapped around their necks. The animals don’t appear to have tags on their flippers to signify they have been rescued.

The Canadian flag was looking a bit tattered, so I replaced it today.

Just before sunset today, there were four eco tour boats in the reserve. The boats were all close to each other, which usually means something interesting is nearby. Sure enough, a pod of five or six orcas were passing westward. They travelled along the north side of the ecological reserve, just south of Bentinck Island and the Department of National Defence base.

Here are some photos from the past two days:

: An entangled steller sea lion with a small rope or plastic strap around its neck. It has been on the island for at least the past two days.

: The california sea lion in the middle of the photo has a plastic strap around its neck. It has been on the island for at least the past two days.
