I will contact NOAA and DFO to report the resighting of the California sea lion with the tag 13-2. The orange tags mean the sea lion was rehabilitated. The tag on the left flipper means the sea lion is a male. I will update the log when I hear back about his history. The rest of the California and Steller sea lions are currently hauled out on Middle Rocks. Perhaps this guy needs a break from the frat party.

A Wonderful Welcome to The Rock!

Posted on by

It has been a year and seven days since I was last here at Race Rocks. This evening, Greg drove me out from Pearson’s maintenance dock at 17:00. Christine greeted us on the dock. After, we quickly switched food bins and bags in the boat before hauling my stuff up the ramp to the house. We did a short walk around and chat to catch me up on the happenings on the island.

Forty minutes later, Greg and Christine set off towards Pearson, but not before having a round the ecological reserve tour.

I have big shoes to fill from the ecoguardians over the past year who have kept this place running smoothly day to day. Every ecoguardian does different tasks as called upon by the season’s elements, needs of the infrastructure, neighbouring species, and projects they take on to better the place. Some ecoguardians are even excellent landscapers, TikTokers, tinkerers, photographers, and so many other things.

Over the next few weeks, I plan to continue fighting the good fight to keep entropy at bay on Race Rocks :) I am going to frequently exercise the winch and station boat, continue to document the other than human (and some human too) species who visit the ecological reserve, do a little scrubbing of windows and solar panels, as well as whatever other tasks might come up.

 

Facility work:

  • Christine left the house and everywhere else very tidy. She also left me notes of today’s vessel traffic and weather before I arrived.
  • There was plenty of sunshine for the solar panels to run the island and top up the batteries. Between 13:00 and 15:00, the average solar input was 5 kWh out of the maximum of 7 kWh.

Vessels:

  • 32 Ecotourism
  • 5 private

Weather:

  • Sky: fog bank in the morning, clearing at noon to be partly cloudy. Clear skies after 14:00.
  • Wind: west 11-19 knots
  • Daytime air temperature: low 14°C, high 17°C
  • Seawater temperature at max flood: 10.7°C

New Man

Posted on by

I left Race Rocks for a dental appointment and returned to find a new man. The male elephant seal looks fantastic and has a smooth, shinny silver sheen to him.  He is still bothering the female elephant seal but at least now she is permitted a piece of subprime real estate, while he lounges in grassy hollow and near the house.

Wildlife notes:

Only a few more gull chicks have hatched with the majority of the gull parents still incubating their eggs.  A different banded gull than that noted on June 20th was found on the southwestern shore. Both gulls were reported to researchers at the Salish Sea Gull Project… read more.  Two surfbirds and one black turnstone visited the northeast rocky beach and one newly fledged California gull on the rocks east of the jetty.

Unwelcomed visitor

Posted on by

The male elephant seal was disturbed this morning to find a new female in his favourite grassy spot.  He chased her around, bit her, climbed on her and sent her down the boat ramp into the water. This all took a while as both had to stop frequently to rest. I had a chance to watch him in the water – effortless!

Wildlife notes:

Still only a few nests have chicks hatching. The chicks that hatched on June 28 are growing rapidly.  They wander less than a foot away from their old nest and sit motionless and cuddled together when an approaching eagle sends their parents to the air.

3 day old chick.

Facility work:

  • cleaned solar panels
  • cleaned windows
  • house cleaning
  • month end report
  • seawater data entry

Partly cloudy, winds SSW to WSW, 11 to 23 knots, high of 16 degrees.

Gull chicks are hatching

Posted on by

Wildlife notes:

The first gull chicks are hatching! I may not be so happy about this in the coming days as the gulls become less tolerant of my presence (I got nailed again today). Just as some checks are hatching, a few gulls are still building nests. This week while lowering the flag before a gale, I noticed a new nest with one egg on the west side of the flag pole base.  Now two sides of the pole could be inaccessible should they protest.

The elephant seal has become interested in the crawl space under the Keeper’s house. He’s pushed against the crawl space door and succeeded in dislodging it. I also caught him glancing in the basement window. I hope he never sees his reflection.

Facility work:

We had trades people at the site today.  The woodstove and chimney were cleaned and the fire bricks replaced. This inspired me to do some cleaning inside the Keeper’s house that didn’t require much water like windows and other shiny things.

  • cleaned solar panels
  • cleaned Keeper’s house windows
  • cleaned inside Keeper’s house
  • thistles

Windy Day

Posted on by

It was a windy day – blew the door off the Derrick Shed and the hair off the elephant seal’s head. The electric fence suffered from the winds over the past few days and needed replacement strands in two sections.

Wildlife notes:

The pigeon guillemots were around in the morning and mostly left again by 7pm. I found what I assume to be a pigeon guillemot nest in the rocks at the west end of the helipad.  Judging by the egg orientation, the little bone and other items which get moved around, it seems to be an active nest. Two least sandpipers were spotted on the northeast shore.

Facility work:

  • cleaned solar panels
  • replaced 2 sections of electric fence
  • thistles – new record, an 11″ root.
  • topped up battery fluid

Weather:

WNW 13 and clouds in the morning, clearing early afternoon with winds building to WNW 33 by late afternoon.

White stuff

Posted on by

The male elephant seal is an unsightly mess. His hair is falling out, he is covered in flies, foaming from the nose and has a poo smear running the length of his belly from dragging himself through his excrement. He probably can’t see well, is slow moving, uncoordinated, and can’t grab a hovering gull <1 foot away from his open mouth.

To be fair, we are seeing him at his worst. In the sea, this creatures is an extremely manoeuvrable master diver and hunter! He can easily hold his breath for 20 minutes and dive to 800 m (maximums of up to 100 min long and 2 km deep have been recorded). His eyes have adaptations for low light, his vibrissae (whiskers) can detect vibrations, he can reduce blood flow to his extremities, has a large blood volume with a high red cell count and can store extra blood in his abdomen and spleen to release slowly during his dive. And that white stuff oozing from his nostril?  It is a pulmonary surfactant that reduces the surface tension of the fluid in the lungs but it also acts an anti-adhesive. When he dives to great depths the pressure is so high his lungs collapse and this surfactant stops the lung tissue from sticking together allowing the lungs to later expand again.

An elephant seal moving on land is anything but graceful. Their rear flippers are not useful for locomotion on land. They use their front flippers to propel themselves forward on their bellies. Their forelimbs or front flippers however, are capable of precise, controlled movements, perfect for getting that itchy spot or wiping away the flies.

Wildlife notes:

Single eagles visited today. The gulls would really have an easier time if they just worked together in both scaring off the eagles and dealing with the steamroller elephant seal. While all the gulls are flying about and screaming bloody murder, only one brave gull chased the eagle on two trips around the Great Race and the surrounding islands.  The male elephant seal has lost more hair on his nose, around his eyes and the hair on his body is coming off in patches.

Race Rocks Ecological Reserve Warden’s Report June 14 2024

Posted on by

Garry Fletcher, ER Warden for Race Rocks visited the reserve on June 14, 2024

Greg Dickinson from Pearson College provided transport in Second Nature for the following group: 

  • Lisette and Mads – Mads is a  former student and both are volunteering at Pearson College
  • Garry Fletcher – Park Warden
  • James Tuohy – future Ecoguardian
  • Ann Nightingale and Andrew Jacobs – Rocky Point Bird Observatory

Upon docking I was struck by the number of Pigeon Guillemots on the rocks . Although I haven’t checked back in our records, there certainly seems to have been an increase in numbers 

We were greeted by the new ecoguardian  Christine  Chourmouzis .  In addition to having a general survey of the reserve, I was able to direct Christine and James through the process of entering them as editors on racerocks.ca and creating a log and posting it on the Race Rocks website. 

Supplies for the Ecoguardian are off-loaded

 

 

 

 

 

 

Pigeon Guillemots also nest on the island

 

When I was teaching at Pearson College, we often monitored a set of tidepools out on the island’s West side. I checked out those pools again and took photos which show the state of algae growth. Some observations in the tidepool files provide a baseline for comparative studies in the future.  These files are on the tidepools

Today’s observations are in the set of photos below

I checked pool #4 which has a white quartz intrusion through it to see if the white periwinkle snails were still there. 

 

A review of some of the installations on the Island

 

Due to recent notices on social media about the problems that pet owners are having when their dogs get exposed to foxtail , I was concerned about whether there was a similar problem with marine mammals. This guy certainly seems to be enjoying the location however. 

I tried to find the small patch of the rare plant  seaside  plant Romanzoffia on the rocks on the East side of the house.  Unfortunately the area was covered with knotweed now. We will have to check again in the winter. 

The Turkish marsh gladiolus is now in bloom. This is a good example of a garden escape, planted by lighthouse keepers probably as much as 80 years ago, they still come up every summer .
