July 29 and 30

Ecological Notes:

  • I have spotted at least six oystercatcher chicks over the past four weeks, although they are hard to get photos of since they often hide and blend in with the rocks. The parents alert the chicks when I am nearby. On any census day in July, I have only been able to spot three each day. Today I spotted four.
  • I launched the station boat early this afternoon to pick up two volunteers from Pearson campus. On the way to and from Pedder Bay, I slowly and at a safe distance checked out some of the smaller islands that make up the ecological reserve. On the way back with the visitors, we went around the island clockwise to see the sea otter in the east kelp, around the south side of the island, through Middle Channel to see the hauled out sea lions, then landing at the jetty to many watching eyes on the eco tour boats and four elephant seals in the jetty bay.
  • The three juvenile elephant seals (two females and one male), who have been in the jetty bay and on the boat ramp over the past week, have been joined by a large male elephant seal. His huge size, as well as large proboscis (trunk) and back battle scars lead me to believe he is the alpha male I witnessed here in the winter and early spring of 2020. He has also been here as the alpha male for the past two winter birthing seasons. Some past ecoguardians referred to this alpha male as Bernard. I prefer not to anthropomorphize animals. I suspect the three juvenile seals are offspring of the adult male, as the alpha mates with all the females after they give birth. I also believe the juveniles might be the three pups born between December 2019 and January 2020, when I was on the island. They appear to be the correct size for two and a half year olds. They also seem to be friendly with each other as they were in the spring of 2020. See the comparison photo below :)

August 28

Wind: W 16-37 knots
Sea State: calm in morning, up to 1m waves in afternoon and evening
Visibility: 0-15 NM
Sky: fog in morning and evening, clear in middle of day
Temperature: 11-16 °C

There were two visitors mid afternoon from Pearson College to drop off supplies.

Here are some sights from around the island today:

Gentle Winds and Plentiful Wildlife

Weather:

  • Visibility 15+ NM
  • Sky partly cloudy
  • Wind 5-10 knots N
  • Sea state: Calm

Visitors/Boats:

  • Yesterday Laura and Greg came at low tide to deliver fuel and for Laura to teach her online class.
  • Greg came this morning to deliver a load of fresh water which we pumped into our storage tank with the fire pump and hoses.
  • Today we saw a dive vessel in the reserve but no divers. They were fairly close to the wildlife but the sea lions did not seem particularly bothered.
  • One small pleasure craft hovered just outside of the reserve for the majority of the day. They were too far away to see what they were doing, but usually boats like this are fishing.

Ecological:

  • The small seal pup is still here, but she has become more adventurous over the past week. We have seen her napping on the east side of the island, and beside the decommissioned diesel tank on the west side.
  • The sea lion population continues to grow, and so does the smell! We will need to set up more fencing soon before they begin to take over the island completely.
  • The pair of crows that we have been seeing returned today and spent most of their day at Race Rocks.
  • We have continued to observe bald eagles in the reserve. We enjoy watching them swoop overhead and cause a stir amongst the seagulls.
  • One of the seals that we have been joined by over the past weeks was also spotted here in December (juvenile female V173). We are still waiting to hear from the researchers who tagged her to see if there is anything interesting to learn.
  • The elephant seals activity has been uneventful as they continue to moult. They spend their days napping and lounging on our “lawn” or wiggling down to the jetty to soak in the shallow water (and perhaps relieve the itchiness of all that peeling fur!).
  • At low tide yesterday we spotted many neat creatures in the exposed pool on the east side of Great Race Rock: urchins, anemones, crabs, fishes, chitons, barnacles, and tubeworms!

 

Male Elephant Seal Pup Ventures to the Water’s Edge

Wind: yesterday 6-50 knots from E to SW to W, today 9-44 knots from W to N
Sea State: yesterday up to 2 m waves, today rippled
Visibility: yesterday 5-10 NM, today 5-15 NM
Sky: yesterday overcast and rain, today partly cloudy with rain and hail in morning
Temperature: yesterday 4-8 °C, today 4-7 °C
Atmospheric CO2: 414.13 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

A big storm rolled through yesterday, with westerly wind gusts of up to 50 knots. Waves were crashing on the west side and sending spray across the island. There were only a few sea lions on the main island. Others might have been taking shelter in a less exposed place.

The male elephant seal pup was at the water’s edge by the boat ramp. He got his first taste of salt water, as he blew bubbles in the water and splashed around. He might have tumbled down the rocks to get to the water, as he was underneath the wooden walkway several metres above there in the middle of the morning. He eventually made his way up the boat ramp, later being met by the adult alpha male. I thought they were having some father and son bonding time, but it progressed to the adult’s mouth around the pup’s body. They both went their separate ways. The pup didn’t have any bit marks on him, so it doesn’t appear the intention of the adult was to injury the pup.

The lighthouse steps and lantern room got a much needed sweep and mop yesterday, to get rid of the dirt that had accumulated for a while on the 99 steps inside the tower.

The boat from Pearson College came out twice today. In the mid morning, Greg dropped off Hubert and Hamish, who are staying overnight to do some photography. The boat returned in the afternoon with six visitors from Pearson. Heather, Ruth, Sarah, Michelle, Greg and Mark had a quick tour of the island. No other boats were seen in the ecological reserve over the past two days.

Varied Thrush and River Otter

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

Visibility: both days 15 NM
Sky: both days clear
Temperature: yesterday 4-8 °C, today 5-9 °C
Atmospheric CO2: 413.53 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The past two days have been clear. That’s four bluebird days in a row. The sunrises and sunsets have cast everything in a golden light. The views have been incredible of the snowy mountains in Washington State.

There hasn’t been much new activity with birds or mammals. One of the male elephant seals has joined the sea lion cuddle puddle near the crane.

Yesterday evening, a pod of orcas were swimming a few kilometres to the northeast. They appeared to be heading northeast, in the direction of Victoria. It could be the same pod from the previous evening.

There were nine visitors to the island yesterday. Five Pearson faculty and staff came in the morning to tour the island and discuss learning opportunities for Pearson students on Race Rocks. Alex, Ric and his friend came to do an upgrade to the electrical system controls.

The military’s demolition training on Bentinck Island concluded this morning.

Today, three tour boats were in the ecological reserve. Yesterday, there were two tour boats and two members of the navy in a small rigid hull inflatable.

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 elephant seal harem has a new addition. In the early afternoon yesterday, another pup was born. Since December 29, there have been four births, which is a record for an elephant seal pupping season on Race Rocks. Unfortunately, only about half of pups tend to survive, due to aggression from other elephant seals, learning to nurse, weaning and predation.

There were three visitors yesterday to do some maintenance on the desalinator: Greg, Warren and Cole. Warren and Cole got a once in lifetime opportunity to see the elephant seal birth. They were walking from the desalinator building to the main house, when Warren noticed the pregnant seal had more flippers than usual. Within less than a minute, the female slid up a grassy incline and out popped the pup. It seems like she used gravity to her advantage. All the humans went into the house, so as not to disturb the seals. The new mother vocalized with the pup and the pup wriggled around. The pup appeared larger than the other three at birth. Perhaps it is a male, as male pups tend to be larger than female pups.

What followed next was difficult to watch. Just ten minutes after the pup was born, it was attacked by another mother. The elephant seal mother that gave birth to the third pup, tossed around and bit the new pup, drawing blood between the eyes and on the head. After a few attacks and several minutes passing, the new mother appeared to intervene and put itself between the aggressive seal and her pup. The mother that gave birth to the second pup also appeared to intervene, by approaching and also putting itself in the middle. Out of the five adults in the harem, the third mother was the only one that showed aggression towards the new pup.

Today, Alex and Greg visited for a couple hours in the middle of the day to problem solve a power issue that presented itself yesterday. It’s great to have a lot of people on land supporting the various off grid systems on Race Rocks.

Here are a few photos from the past two days of the flora and fauna on Race Rocks:

New Desalinator and New Adult Female Elephant Seal

Wind: 1-44 knots from NE yesterday to W this evening as the wind increased
Sea State: up to 3 m waves breaking on west side of the island
Visibility: 5-10 NM
Sky: overcast with rain and a few sunny patches today
Temperature: 6-11 °C
Atmospheric CO2: 413.70 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It was a flurry of activity on the island yesterday. A big change from having no human visitors for a week and a half. Greg brought seven other people on the boat Second Nature. Three volunteers from the college (Lawrence, Sandra and Vincent) came to help with some maintenance and clean up tasks. John and Mike, from Pacific Coast Fire Equipment, were here to do the yearly inspection of the fire extinguishers. Warren and Ric spent almost six hours doing the electrical and plumbing hook ups and tests of the new desalinator. The desalinator room is very cramped quarters with thick concrete walls and only a six foot high ceiling inside. As Race Rocks legend goes, the building was originally constructed as a fallout shelter for Cold War fears of nuclear attack. It apparently contained emergency supplies and two bunks for the lighthouse keeper and assistant keeper. There was no space for their families. In 1975, the building was converted to a water filtration plant.

The non-human activity was busy too, with the arrival of a new adult female elephant seal. She showed up soon after the boat, staying on the boat ramp for a while before coming up to the middle of the island. The alpha male chased her around, they barked a lot, then she settled in the grassy area between the desalinator shed and the flagpole, where she still is this evening. Now there are two suspected pregnant seals hanging out in the centre of the island near the mother, pup and alpha male. The two other males appear to be keeping their distance. One is near the jetty. The other is behind the house by the compost bins.

The desalinator is running well after a total of nine hours of use. This evening, I was delighted to see that it had pumped 600 L of fresh water into the tank. Combined with the 500 L from yesterday, the desalinator has produced more fresh water than has been used since my shift began on December 21. At this rate, the 4,500 L fresh water tank should be filled up in about a week. At that point, the desalinator will be run regularly, but for shorter amounts of time. It’s an energy intensive way to produce water which consists of a reverse osmosis system and secondary UV filter. The temporary method of getting fresh water while the desalinator was out of commission was also very energy intensive. It consisted of filling up a 1,000 fresh water tank at the college, boating it to the island, and pumping it up to the tank from the boat. The water usage is planned to increase a little bit in the near future, due to some much needed pressure washing of the exteriors of the buildings, to prevent them from being overtaken by algae.

See the photos below for some recent views on the island.
