The youngest elephant seal pup came back ashore, on the east side of the island. She is easy to identify from the scar below her right eye. She spent the evening and night on the southeast side of the house, where she spent several weeks in February and March once she weaned from her mother. Today she had moved around to haul out on the boat ramp and swim in the sheltered water by the jetty.

A new sub adult male elephant seal has joined the other elephant seals. He is a bit smaller than the other sub adult male that joined the last week.

Yesterday there were two visitors, Guy and Corey, in the college boat Second Nature. There were no other boats in the ecological reserve.

The fog signal sounded for an hour this morning, before the sky cleared. It hasn’t sounded for almost two months. The fog signal is (3) 60 s, which means three blasts sound and repeat every minute. The more detailed version is blast 2 s; sil. 3 s; blast 2 s; sil. 3 s; blast 2 s; sil. 48 s.

April 5 and 6 – Orcas

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.

March 30 and 31

Wind: yesterday variable 4-40 knots, today W 3-25 knots
Sea State: yesterday up to 1 m chop, today rippled
Visibility: yesterday 10 NM, today 15 NM
Sky: yesterday partly cloudy with rain in morning, today clear
Temperature: yesterday 5-8 °C, today 5-7 °C
Atmospheric CO2: 415.65 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

I took soundings on all the water and fuel tanks as well as other notable measurements for the month end report. Here are some of the numbers. The desalinator produced 6,650 L of water, which was used mostly for pressure washing the buildings and other cleaning. 540 L of diesel was used to run the generator to top of the batteries, when there wasn’t enough sun to charge the solar panels. The generator ran for 141 hours over the month, for an average of 4.5 hours/day. There were 24 visitors (16 unique visitors) to the island over the course of the month.

No boats were seen in the ecological reserve over the past two days.

See the gallery below for views around the island.

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.

4 elephant seals (1 adult female, 2 female pups, 1 male pup)
10 steller sea lions

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.

In the middle of the day yesterday, a sea otter floated and swam near the south islands. It looked small in comparison to the nearby blimp like harbour seals.

The alpha male elephant seal left the island at some point last night. As of the sunset this evening, he hadn’t returned. The elephant seal pups have spread out from where they spent the past few days, near the bushes in the middle of the island. For most of the day, the three pups were sunning themselves on the grass between the science house and the lighthouse.

The gulls and Canada geese are acting more aggressive. The number of gulls is still fairly low, but they are spread out around the islands. I often see them pulling at each other’s wings. Perhaps they are trying to claim the preferred spot. The Canada geese frequently honk and charge at each other with their necks horizontal.

Many of the daily tasks involve keeping the human life sustaining systems running. I spent a couple hours each of the past two days preparing firewood for next winter. All winter, I have been collecting logs that wash ashore on the boat ramp. I rebuilt the chainsaw cutting jig, got suited up in the chainsaw safety gear and bucked up a lot of logs. The salt will get rinsed off the wood some more in the rain, as the wood waits to be split and stacked in various indoor spaces over the coming months.

Yesterday, four tour boats were in the ecological reserve. Today, there was one tour boat.

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)

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.
