Sea: rippled in morning, up to 2′ chop in afternoon
Air temperature: 11-15 C

DND Blasting:
There was one DND blast at 14:05 on July 12 at nearby Rocky Point.

Visitors:
Greg and Bruce visited this afternoon to deliver 1,400 L of freshwater and a new first aid kit.

Maintenance:
I did the routine tasks of cleaning the solar panels and house windows, topping up the water in the 24 deep cycle batteries, fixing the electric fence, tidying, and maintaining the freshwater system.

Ecological notes:
There have been a lot of humpback whale activity over the past few days to the west, south, and east of Race Rocks. The whale watching boats have been active in the area. From what I hear on the VHF radio, they have been very pleased with the humpback viewing. I have not seen any whales swim through the ecological reserve.

I heard back about the tagged elephant seal, from the researcher at Año Nuevo Natural Reserve, in California. The juvenile seal, tagged H999 and K646, is a male who was born in January 2022. He was previously observed here and reported to the researchers on April 1, 2023. He has been moulting here for at least the past several weeks. He appears to be almost complete the moulting process, so he might be moving on soon to feed in the deep waters.

Weekly Census observed on July 13:
elephant seal: 1 juvenile (tagged H999, K646)
Steller sea lion: 3
harbour seal: 79
bald eagle: 2 adults, 1 juvenile
raven: 1
cormorant: 7
black oystercatcher: 6 adults, 1 chick (that I could spot today)
pigeon guillemot: 148
glaucous-winged gull: 387 adults, 120 chicks
surfbird: 12
killdeer: 4
western sandpiper: 3
barn swallow: 3

Gull Chicks Everywhere

Posted on by

It is great to be back as the Ecoguardian at Race Rocks. I have been lucky enough to spend a total of almost seven months here between 2014 and my last shift which ended on September 1, 2020. I have been spending the past three and a bit days reacquainting myself with the island and infastructure. I have not stayed here before in July, so it is taking some adjustment to live in harmony and not disturb hundreds of nesting gulls. It drastically limits where I can go on the island.

Ecological Notes:

  • The glaucous-winged gull population is increasing everyday with lots of chicks hatching. I do my best to avoid getting close to the nests. I move quickly by the ones near doors and pathways on which I need to travel to get to the energy building, jetty and lighthouse.
  • A pod of orcas swam westward through the ecological reserve on Saturday, July 2, then went eastward in Race Channel. The orcas continued to head eastward, with at one point 14 ecotour boats viewing them from a safe distance.
  • A juvenile male elephant seal, tagged D018/D019, has been hanging around here for a while this spring and early summer. I noticed the tags this weekend, so I could confirm it was the same seal that Ecoguardian Joan spotted on the seal’s arrival on the island on May 19. Here is a link to the tagged resight histories, when I spotted this seal in April 2020 and reported the details to the Director of the Año Nuevo Reserve, in California. The brief version is he was tagged in February 2017 as a pup in Año Nuevo. He was first observed at Race Rocks in April 2018. He was again spotted here in April 2019, December 2019, and April 2020. His proboscis (nose) and body has grown a lot in the past couple years. I wonder what adventures he has gone on in that time.
  • I know of two black oystercatcher chicks that I have seen through the binoculars and  long lens of the camera. One is hanging out near the jetty with its parents. The other is hanging out near east bay with its parents. The dark grey fluff ball chicks are hard to spot, as they blend in well with rocks.
  • See the photos below for these and more ecological sights.

Weather:

  • The wind has been consistently coming from the west over the past four days that I have been here.
  • Friday and Saturday were part cloudly with lots of sun to fully charge the solar panels by 17:00 both days.
  • Sunday and Monday were overcast with periods of rain and fog.
  • The temperature in the past four days has ranged between 11 to 14 oC.

Visitors:

  • Greg drove the boat on the afternoon of Friday, July 1 to do the shift changeover between Jillian and I. Thanks, Jillian, for leaving the place in such great shape.

Vessel Traffic:

  • Many Canadian and American ecotour boats have been nearby throughout this long weekend.

April 11 and 12 – Weekly Census

Posted on by

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
Sky: yesterday partly cloudy then clear from mid morning, today clear
Temperature: yesterday 8-14 °C, today 7-14 °C
Atmospheric CO2: 416.33 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

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.

Census results observed this afternoon at low tide:
10 elephant seals (1 female pup, 1 female juvenile, 1 juvenile, 2 sub adult males, 5 female adults)

5 bald eagles (2 juveniles, 3 adults)
16 Canada geese
1 black brant goose
99 gulls (mostly thayer’s)
17 pelagic cormorants
4 brandt’s cormorants
5 double-crested cormorants
6 black oystercatchers
24 pigeon guillemots
7 harlequin ducks
2 surfbirds
5 black turnstones

  • Two eagles on Turbine Rock and a colourful sailboat passing through Race Passage.
  • Newly arrived juvenile elephant seal tagged G512 and E779
  • Green tags G512 and E779 on the juvenile elephant seal.
  • Newly arrived sub adult male elephant seal tagged C887
  • Green tag C887 on the sub adult male elephant seal
  • Black brant goose
  • Four elephant seals waiting for the water to come to them
  • Newly arrived juvenile seal exploring the boardwalk
  • A view from the top of the lighthouse this afternoon of the clear water of the east bay. A group of sea lions can be seen on the rocks.
  • These lucky gulls won of the goose egg hunt

Wind: yesterday variable 1-11 knots, today mostly W 2-17 knots
Sea State: both days calm
Visibility: yesterday 5-15 NM, today 10-15 NM
Sky: yesterday overcast, rain then clearing in early afternoon, today partly cloudy then clear from mid morning onwards
Temperature: yesterday 5-6 °C, today 5-10 °C
Atmospheric CO2: 414.34 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

I heard back about more information on the recently arrived female juvenile elephant seal pup, with green tags E103 and E135. Dr Patrick Robinson, the Director of the Año Nuevo Reserve and Lecturer at University of California Santa Cruz, sent a report of the history of the seal’s sightings and said, “It’s always great to get these updates… we greatly appreciate it!” The seal was born in the 2018 winter season, which makes her just over two years old. She was seen a lot during the winter and spring of 2018 at Año Nuevo Reserve. Researchers took two blubber samples to study bioaccumulation. The seal wasn’t seen again until the fall of 2019, when she spent a month at Race Rocks between September 7 and October 11. Fast forward a few months, the seal came back to Race Rocks two days ago, on March 23. She appears to be in the early stages of her catastrophic moult of her fur and skin, judging by the patches on her sides.

The youngest elephant seal pup returned yesterday morning from her one day adventure in the sea. She spent the whole day sleeping by the wood pile. The oldest pup has been gone for the past two days. A new adult female elephant seal arrived yesterday. She is most likely one of the four mothers that was here in January and February. So far the three have come back a month and a half after they each weaned their pups, which happened on January 21, February 4 and February 9.

At today’s 16:31 high tide, after recording the salinity and temperature of the water, I hooked up the hoses and pump to top up the seawater in the cistern. The gas powered water pump sucks water through a hose with a strainer dropped off the end of the jetty. The water is pumped through 76 m (250′) of fire hose up to the cistern. Over a couple hours, tens of thousands of litres of water were pumped into the underground cistern, which should feed the desalinator for the next month and a bit.

Yesterday, there was one pleasure boat that zoomed through Middle Channel and stopped by the rocks to take photos of sea lions. This afternoon, the Canadian Coast Guard lifeboat Cape Calvert, appeared to be out for a cruise around Race Rocks from the base in Victoria. They came in for a closer look and a couple of the crew appeared to be snapping photos of Race Rocks with their phones. This is a very photogenic place. This afternoon, Guy, Corey and Christine from Pearson College delivered a new fridge and took away the old one that recently stopped working. They also brought some fresh food from the Pearson kitchen, which is closing down for a while.

Here are a few photos from the past two days:

Seal Studies and Helicopters

Posted on by

We received a response from the scientists who had tagged the elephant seal mentioned and pictured in this previous post. They were able to share some interesting information about GE103, whom we nicknamed Eric. GE103 was part of a mother and pup interaction study, as well as the subject of a blubber biopsy study.

 

“Eric”, GE103

Juliette Linossier, a researcher working under a Fyssen grant at UC Santa Cruz/Año Nuevo Reserve, was able to tell us more about the early life of this animal and others. She told us that shortly after the birth of another elephant seal (GE338), there was a huge storm at Año Nuevo and GE338 was separated from it’s mother. The pup was stuck on the beach, and his mother in an protected elevated area. They called to each other for a long while, but were never able to return to each other. GE338 did survive but was nursed by another female in the colony.

The now ’empty nest’ mother of GE338 became attached to GE103! She nursed him, and stayed close to him and his mother, G9474. Thus, GE103 (or as we call him, Eric) was able to take advantage of more than one milk source as a pup; the two mothers even fought over him from time to time.

According to her bio, Juliette wants to investigate the link between allonursing and maternal cognitive abilities using new approaches. Using time-lapse photography, chemical profiles and other techniques she plans to look at variables such as maternal age, pup similarity, genetic connection, spacial proximity and more to further understand what drives allonursing in these interesting creatures. Thanks for sharing, Juliette!

GE103’s blubber biopsies were taken for the purpose of furthering the understanding of pollutants bioaccumulating in marine mammals. Read more about this subject here.

Many thanks to Patrick Robinson, director of Año Nuevo Reserve and lecturer at UC Santa Cruz, for helping us learn more about this work.

We left Race Rocks last Monday (October 30th), and hours before leaving we were surprised by the landing of a Bell 412EPI Coast Guard helicopter. They came to Race Rocks in order to replace the solar battery bank beside the foghorn (near the base of the lighthouse). We were able to get great video of them landing as well as taking off!

Unfortunately, as one can see at the left of the video the landing scared many sea lions off of the rock in a rush. Without knowing that they were coming we had no chance to gently move any vulnerable animals away from the helicopter pad. We were able to speak with someone at the college about this, and the Coast Guard will hopefully be able to better work with Race Rocks in the future to ensure the safety and comfort of the animals.

The pilot was kind enough to take a moment to show us around and allow us to take some pictures. He explained that a smaller helicopter could have been landed near the house, but the 412EPI’s cargo capacity (over 6000lbs) was needed to transport the batteries. The helicopter is powered by a Pratt & Whitney PT6T-9 turboshaft engine that makes over 2000hp (about 1500kW), and it’s made in Canada!

We enjoyed our time at Race Rocks (a big thanks to everyone who supported us during our term), and hope to return and continue this work protecting and observing the fragile ecosystems and the animals within. Until next time!
