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.

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.

 

Varied Thrush and River Otter

Posted on by

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.
6 elephant seals (3 adult males, 2 female pups, 1 male pup)
8 steller sea lions
60 california sea lions
30 harbour seals
1 river otter
6 bald eagles (3 adults, 3 juveniles)
2 Canada geese
1 raven
20 brandt’s cormorants
10 double-crested cormorants
62 pelagic cormorants
101 gulls (mostly thayer’s gulls)
6 black oystercatchers
10 harlequin ducks

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.

Three Weaner Elephant Seal Pups

Posted on by

Wind: yesterday 2-15 knots from E to N, today 3-10 knots from S to N to E
Sea State: yesterday and today rippled
Visibility: yesterday and today 15 NM
Sky: yesterday and today clear
Temperature: yesterday 5-7 °C, today 5-8 °C

The past two days have been sunny, which means the animals and scenery are very photogenic.

There was lots of activity with the elephant seal harem today. Overnight, the third mother left the island, after nursing her pup for 24 days. Her pup is now a weaner, no longer getting milk from her mother. The three mothers whose pups survived all stayed for 24 days. The last female, who’s pup died 17 days ago, left late this morning. After the male mated with her, she was either trying to get away from him or was chased down the path and out into the water by the boat ramp. The alpha male left for about an hour, perhaps to get some food. He’s been on the island the longest of any of the elephant seals. He hasn’t eaten or left the island since before the first pup was born on December 29. That’s almost as long as I’ve been here without leaving, except I eat three meals a day. The female elephant seals will most likely return to Race Rocks exactly eleven months after they left, to give birth to another pup. Stay tuned to the Log next December and January for more pupping season drama.

Now that there are no adult female elephant seals left on Race Rocks, the alpha male’s role has changed from mating with the females, to protecting the three pups that remain. The alpha male is most likely father to all of them, as he was the alpha male last year as well.

Three beta male elephant seals are still on the island. One left for about 24 hours and returned this afternoon. When he slid up the ramp onto the island, he appeared to look around to see if any females were around. Then, he headed for the oldest pup and put his mouth around it. He didn’t appear to be trying to hurt it because no blood was drawn. The pup was screaming. The alpha male came over and scared away the beta male. For the afternoon and evening, the three pups were lying in the grass about 10 m away from each other. It will be interesting to see if the pups interact with each other, as they have in previous years.

Some other interesting sights were a sea otter, two black brant geese, and a very bright Venus visible in the western sky for a few hours after sunset for each of the past three nights.

There were no visitors to the island in the past two days. Four pleasure boats and three tour boats were seen in the ecological reserve.

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.

Groundhog Day

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.

Wind: yesterday 5-20 knots from W to N, today 0-40 knots from N to W
Sea State: yesterday rippled, today calm in the morning and up to 1 m chop in the afternoon
Visibility: yesterday 0-15 NM, today 1-10 NM
Sky: yesterday fog then sun, today overcast and rain
Temperature: yesterday 7-9 °C, today 8-15 °C
Atmospheric CO2: 413.95 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It’s been a mix of weather over the past two days. Yesterday began with the fog signal beeping. Later in the morning, it got sunny. It was overcast this morning and afternoon. This evening, it got quite warm up to 15 °C and wet as a storm came in from the west.

There were six ecotour boats in the reserve over the past two days.

Three visitors were on the island today to work on the generator. For at least the next few days, the island is still on backup power. The web cameras and several other non essential systems on the island will remain off to conserve energy.

See the photos below for some views 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.

For the past two mornings, there were many bald eagles in the ecological reserve. Today, 34 were seen perched on the West Rocks. Many more were catching fish and perched around the other islands. There appeared to be a lot of fish in the water, based on the swarms of gulls, cormorants and the feasting bald eagles.

This afternoon, two whale watching boats toured around the islands after watching the orcas in J pod, which were a few kilometres to the east and south of Race Rocks. Two other eco tour boats were seen in the ecological reserve over the past two days.

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