April 11 and 12 – Weekly Census

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.

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

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.

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

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

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.
