Wind: yesterday W-S 0-32 knots, today W-SE 2-17 knots
Sea State: both days calm
Visibility: yesterday 10-15 NM, today 15 NM

The lawn in front of the house got busier this morning with nine elephant seals, two more than yesterday. A tenth seal, the pup, was near the jetty. The two new arrivals have green tags on their tail flippers. One is a male tagged C887. The other is a juvenile tagged G512 on the right flipper and E779 on the right. I will update the information on age and past sightings when I hear back from the researchers. The green tags signify the elephant seals were tagged at Año Nuevo, south of San Francisco.

[UPDATED April 13: I heard back from Dr. Patrick Robinson, the researcher from Año Nuevo Reserve. The elephant seal with green tags E779 and G512 was tagged as a pup in February 2019, where he was born at Año Nuevo. This is the first time the male juvenile has been spotted outside of Año Nuevo, where he was last seen as a weaner in March, 2019. The elephant seal with the green tag C887 is a juvenile male that was born at Año Nuevo in February 2017. He has been seen at Race Rocks in the month of December in 2017, 2018 and 2019.]

There was one boat seen in the ecological reserve on each of the past two days, a pleasure boat yesterday and a sailboat today.

A sea otter spent most of yesterday afternoon in the South Channel between South Islands and South Seal Rocks. It ate clams, cleaned itself and rested on the rocks. When it dove underwater to grab some more food, I approached to get a closer view from an indent in rocks on South Seal Rocks. See the 16 second video below.

The last elephant seal pup appears to have left today. She was swimming in the jetty bay for most of the day. When I went out in the boat this afternoon, she was floating by the rocks to the north of the jetty bay. When I returned, she wasn’t there anymore or on the land. All three surviving pups left the island within a week of being three months old. The two others haven’t returned. Presumably, they are off feeding themselves after teaching themselves to swim over the past two months, since they weaned from their mothers.

I moved four wheelbarrows of the remainder of this winter’s supply of wood from the cupboards beside the Energy Building to the basement of the house. That wood should last for any cool or damp days of the spring or fall. I fixed some loose boards on the winch deck and boardwalk. Over the winter, the sea lions were rough on that deck.

A single blast was heard yesterday morning just after 11:00, coming from the demolition training area at Rocky Point.

One pleasure boat was seen in the ecological reserve this evening. The Race Rocks station boat was out this afternoon for a quick trip to Pearson College to pick up groceries.

  • Just a few big chunks of fir and skin around her middle remain to moult. T562/T653 is almost done.
  • Sea otter swimming in South Channel in the clear water, as seen from the lantern room of the tower
  • Deconstructed shore crab
  • Watching a sea otter from the south side of the island yesterday evening. See the video below.
  • The full moon rising yesterday evening just after sunset
  • When I headed out in the boat in the late afternoon, the youngest elephant seal pup was floating in the water by the rocks, near a resting california sea lion.

April 5 and 6 – Orcas

Posted on by

Wind: yesterday variable 0-17 knots, today variable 0-22 knots
Sea State: both days rippled
Visibility: both days 15 NM
Sky: yesterday partly cloudy, today clear
Temperature: both days 5-10 °C
Atmospheric CO2: 416.03 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday morning, I noticed a pod of at least six orcas on the western edge of the ecological reserve. They swam east through Middle Channel, passing just north of the main island. What a treat it was for me to watch them from the front porch. See the photos below.

The older of the two female pups has been gone for the whole day. She left the island at some point early this morning. It’s been 14 days since the oldest of the three surviving pups left the island. Perhaps the pup who left today is following the strict schedule, as she is 14 day younger than the male pup who left 14 days ago.

Today, there were three boats in the ecological reserve: two pleasure craft and one local whale watching boat with two people on board.

  • This gull managed to snatch an egg from a goose nest
  • The large dorsal fin of a male orca and a smaller female.
  • A younger male orca swims by two california sea lions.
  • Orcas swimming by a juvenile bald eagle. The shorelines of Esquimalt and Victoria are in the background.
  • The older of the female pups was resting on this spot above the goose nest for two days, before she went for a swim at some point this morning. Notice the calendula flower in her mouth.
  • This tulip, surrounded by grape hyacinth is taking its time to blossom.
  • Blue bells are starting to appear in a few place.
  • The juvenile elephant seal scared away the goose from this nest with two eggs. The goose came back after the seal left.

Spring Census and Swimming Seal Pups

Posted on by

Wind: yesterday W 0-30 knots, today mostly W, SE in early afternoon 1-28 knots
Sea State: both days calm in morning, rippled in afternoon
Visibility: both days 10-15 NM
Sky: both days clear

All three elephant seal pups were swimming near the boat ramp both yesterday and this morning. The middle aged pup has taken to a napping spot on the concrete between the boat ramp and the rocks.

When I did the census observations today, I was surprised there were only 84 pigeon guillemots. I counted twice to make sure. The little black and white birds with bright red feet appear to be everywhere around the shoreline and in the water around the main island. They are constantly moving about and making their high-pitched whistling call.

I had a great view of a sea otter this afternoon. While out in the boat taking a photo of the main island, I heard what sounded like a slapping sound on the water. I turned around to see the sea otter about 20 m from the boat crack open clamshells on its chest. The otter had a few clams lined up. I turned off the engine and watched the otter quickly eat a few clams, then repeatedly dive down and eat more.

Today, there were nine pleasure crafts, one sailboat and the Race Rocks station boat in the ecological reserve, the most boats of any day this year. A pleasure boat with five people stopped at the jetty this evening. Three people walked along the jetty to get a closer look at the elephant seal pup napping beside the boat ramp. I approached and drew their attention to the large sign that explains the purpose of the ecological reserve and that permission is needed to come ashore. They were very nice and asked a few questions about the marine mammals before they left. No boats were in the ecological reserve yesterday.

Census results from today:
4 elephant seals (1 adult female, 2 female pups, 1 male pup)
10 steller sea lions
82 california sea lions
1 sea otter
50 harbour seals
8 bald eagles (3 adults, 5 juveniles)
11 brandt’s cormorants
6 double-crested cormorants
19 pelagic cormorants
9 Canada geese
251 gulls (mostly thayer’s gulls)

Here are some photos from the past two days:

Two short videos of the youngest elephant seal pup learning to swim in the shallow water. In the first clip, she appears to be playing with a little bull kelp. In the second clip, she is blowing bubbles. The sounds of many species can be heard: california sea lions, thayer’s gulls, black turnstones and pigeon guillemots.

The wind was strong all day yesterday until mid afternoon today, when it began to die down. The cool temperatures and winds blasted some of the plants that were exposed on the north side. The high pressure and clear skies were great for the solar power. For the first time this winter, the batteries recharged themselves today, reaching full charge just after 4:00 this afternoon. Normally, I top the batteries up with the generator for a few hours each evening. Hopefully the voltage of the batteries will remain at a good level until the sun rises at 7:24 and begins to feed the solar panels soon after.

For the past two and a half months, I have been combing the shoreline, picking up all the trash that washes ashore. I picked up a lot of pieces of plastic, rope, foam, fishing gear, buckets and other things that floated their way here. There are only three small beaches on the island that collect garbage: the boat ramp, east bay and the tombolo, which at low tide connects the south side of the island with the south seal rocks. There must be a massive amount of trash that floats by Race Rocks and doesn’t get captured by the shoreline. On the south side of the island, I found a lot of metal and pieces of ceramic that were mostly from the days when the old things and buildings on the island were disposed of by pushing them into the water. A few of the items I found are going to be reused: dog toys, floats and rope. The rest will be either recycled or sent to the landfill.

There were two tour boats in the ecological reserve this weekend, both today.

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
