Clouds

Posted on by

Since June 11 this is the first time I have run the generator. It was only at 80% capacity by 2:30pm. On a sunny day it would be close to 90% by this time. The generator ran for 4 hours and brought the batter from 80% to 99% – shame, something the sun could do without the use of fuel.

Wildlife notes: 

The black oyster catchers near the house have moved their two chicks closer to the water on the north east shore. The chicks appear to have almost doubled in size in a week. They are exploring the rocks but quickly respond to their parents peeps and take cover when instructed.

A California and a Stellar sealion were spotted in the early evening on the south east shore. The Stellar has an injury at the base of its flippers.

First day of summer

Posted on by

It is the first day of summer and I am wearing a toque and have a fire going! I heard the fog horn for the first time today. It isn’t very loud and doesn’t appear to disturb the birds – three long blasts (more like beeps) every minute, sounds like a truck backing up.

Wildlife notes: 

The elephant seal is now molting around his face. It appears he is not just losing his hair and a layer of skin but also some of his front whiskers.  No new wildlife sightings today. The sea lions are still away and the geese have left.

Facility work:

  • cleaned solar panels
  • topped up battery fluid
  • clean and vacuumed the battery room
  • thistles

Sunny with 10 knot westerlies in the morning building to over 30 in the early evening. Fog rolled in at 1 pm and dissipated by 7pm.

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 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

 

 

 

 

 

 

 

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

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 are now in bloom. This is a good example of a garden escape , planted by lighthouse keepers probably as much as 80 years ago .

Wildlife notes:

A few new exciting sightings today.  Two purple martins were spotted on top of the tower and on roof of the Keepers’s house around noon.  At 3 pm I discovered a purple martin had made its way down the chimney pipe into the wood stove. I am so glad the ashes were cold and I was able to get it back outside! A striking male harlequin duck visited the small bay on north east side of the island. A banded gull was observed.

Water water everywhere and not a drop to drink

Water delivery:

A desalinator is used to produce fresh water at the Rocks. It hasn’t been working for several weeks, and while waiting for parts, we needed to boat in fresh water. Today Greg and Cedrick ran two fresh water delivery trips to the island. The water is pumped from a tank on the boat to the fresh water tank near the house using fire hoses.  Over the past week since I arrived, the water reservoir went from 1600 L to 1500 L. This an average use of 15L a day for the mandatory solar panel and window cleaning and for house use but with careful conservation (e.g. no daily dish washing, few and quick showers). An interesting water note: with the 10m run from the hot water on demand system to the shower, about 8 L of water will run from the faucet before hot water reaches the shower. In our city homes we let this amount of water run down the drain all the time – here I catch it in a bucket.  With today’s delivery of 1400L water today, our supply is up to 2900 L.  After tomorrows delivery, the tank should be full and I can consider doing a load of laundry at a cost of 150L of water!

Facility work:

  • cleaned solar panels
  • water delivery
  • thistles
  • “weed whacking” – cutting grass from the walkway

Wildlife notes:

Eagles visiting again, the four Canada geese remain, and the elephant seal flattened at least one more nest. The gulls who had the interaction with the seal in yesterdays post, lost their last egg today – cause unknown.

All in the day of a gull

Posted on by

The elephant seal typically spends his mornings sleeping the grass near the east-west walkway leading from the Jetty to the Energy house. In the afternoon he moves to the east side of the house perhaps seeking the shade. He often moves in quick short bursts and with no regard to the gull nests in his path.  Today I watched him place himself on top of a nest near the house.

The gulls go to have a look for their nest which is mostly beneath him.

The seal reaches but can’t manage to grab the gull out of the air.

 

Eventually the seal moves a bit and the gull can take a look

and they eat the rest!  A few minutes later, she back on the nest as though nothing happened.

Facility work:

  • cleaned solar panels: from 12-1 pm generated 7.1kW !
  • thistles
  • chopped kindling

Wildlife notes:

Several eagles visited throughout the day causing great commotion. The oyster catchers seem to be the first to raise the alarm.  The California sea lions were notable absent from their regular spot near the Jetty. The four Canada geese are still here.

New window washing pole!

Tools

Greg brought a new 24′ telescoping window washing combo pole with both a squeegee and pad! It was pressed into action for the first time on the Student House today.  It doesn’t have the classic charm and ingenuity of repurposed old pot brush tool and may not last as long but it sure works well! Thank you Greg!

Thistles

Posted on by

Thistles:

During yesterdays visit, Garry Fletcher remarked on the expanding thistle population around the tower base and suggested they be pulled. Today I started to tackle this job.  The thistles have a tap root that connects to a horizontal root which can spread many feet.  The thistles are growing in patches where many of the plants could be connected to the same horizontal root.  When a larger plant is pulled, the tap root breaks at this junction and reveals the depth of the horizontal root.  The longest root so far is almost 10″ long suggesting there is in places 10″ of soil on Great Race Rock! Only the smallest of plants, which may have germinated from seed, can pulled with the entire root intact. Today I cleared 2 square meters – a bucket of small ones and bundle of larger plants.  I plan to do this amount each day (more would be too hard on the back). I may not finish before I leave but with the horizontal roots still in the soil, this may be a yearly task.

Developing thistle flowers and the longest root of the day.

Facility work:

  • cleaned solar panels

Wildlife notes:

No new wildlife sightings to report. The gulls continue the mate and fight, and the Elephant seal spent his day sleeping in the grass.

E-Bird June Race Rocks gull survey and Census

Posted on by

E-Bird Gull Survey https://ebird.org/checklist/S184107190

Subject: June Racerocks Gull Survey

Rocky Point Bird Observatory & Pearson College Race rocks Gull Survey June 2024
Survey conducted by Andrew Jacobs and Ann Nightingale
Thank you to Greg for getting us out there again on the boat and Christine with the assistance during the survey.
This survey was conducted to investigate the phenotypes of the glaucescens-occidentalis hybrid complex using the Great Race Rock as a nesting area. We looked for pairing preference of phenotypes, nest habitat preference and mapped the nests that had parents on them. We looked at the breakdown of the colony diversity into five phenotypic groups – pure type Glaucous-winged Gulls, Glaucous-winged trending hybrids or light morph Olympic Gulls, intermediate trending hybrids or intermediate morph Olympic Gulls, Western trending hybrids or dark morph Olympic Gulls, and pure type Western Gulls. The nesting of Western Gull on the island is of specific interest as there are adult Western Gulls near the island year round and we would like to see if Western Gull pairs are starting to breed in Canada or if they are forming mixed pairs.
The survey also counted other species of gull and age classes as well as other species using the rocks this time of year. The general nesting grounds on the main rock were used by the hybrid complex, Pigeon Guillemot, and Black Oystercatcher although no nests of the latter two were seen they were displaying as if nests were nearby.
Ebird link with photos and sound recordings.
The numbers of pure type Glaucous-winged Gull were up for the breeding season over our previous survey by about 6-7 times at 69 individuals with 64 adults and 5 immatures. The number of hybrid and intergrade type Olympic Gulls was 321 with 314 adults and 7 immatures. The breakdown of colour morphotypes in the Olympic Gulls was light morph (Glaucous-winged trending hybrids) 138 individuals with 133 adults and 5 immatures, intermediate morph (Intermediate trending hybrids) 166 individuals with 164 adults and 2 immatures, dark morph (Western trending hybrids) 17 individuals with 17 adults.
The island at this time contained 4 adult Western Gulls, two of which were on nests, one was in the grassy area on a rocky outcropping and one was on the outer rocky part of the island along the cliff. The two nesting Western Gulls did not have a partner present while we were on the island. Surprisingly one of the Western Gull nests appeared to have a rock placed in with its three eggs in the nest of roughly egg size.
Total glaucescens-occidentalis hybrid complex birds 394
Glaucous-winged Gull 69 (17.51%)
Olympic Gull 321 (81.47%)
-Light morph 138 (35.02%)
-Intermediate morph 166 (42.13%)
-Dark morph 17 (4.13%)
Western Gull 4 (1.01%)
