Race Rocks ER #97 Warden’s Report May 2025

Posted on by

Ecological Reserve warden Garry Fletcher went out to Race Rocks in May  2025 with Laurag Verhegge and Isabelle Groc on the new Pearson College Boat with College staff Richard and assistant and  electrician Jordan Cole  .,

At the mouth of Pedder Bay near the small island on the north side we came across a sea otter foraging for crabs. This was a great opportunity for Isabelle to get some good photos for her project she is doing on Sea Otters.

On our arrival at the Ecological Reserve,  we were greeted at the jetty by the Ecoguardian hired by Lester Pearson College, Christine Chourmourzis. Christine will be there through  the next few weeks in July . I might add that I have appreciated her excellent coverage of events at Race Rocks in this log for this website, and she has been an effective warden in looking after the operations on the island.

7One female elephant summer has stayed on the island for the summer, normally they have all left by now and return later in the year. she is moulting now.   one photogenic California Sea lion also greeted us on arrival.

Chriistine  has also discovered several new plant species on the island . showed these to me and i have posted them on iNaturalist where they can be seen at the following link: Eventually they will get their own page in the Biodiversity section here.

I was not able to find any Romanzoffia or mist maidens in one of their usual spots but the long ago introduced Turkish gladiolus has spread to a few new locations East of the Ecoguardians residence.

 

The Glaucous winged gulls were in full nesting mode and one agressive adult even knocked my hat off while I was on a sidewalk.

One nest contained eggs of different colours .. iI am not sure if that is normal.

records are not being recorded on the Davis weather instrument and after a full cleaning some sensors are still not recording so we are looking into that.

 

 

 

 

 

 

we will be asking BC Parks for a replacement of the ER sign , I has withstood the harsh environment for a good length of time now but is showing wear and missing one section.

 

 

 

Christine did the seawater measurements while we were there, A probe is lowered of the end of the jetty to a metre depth every day near high tide These records are submitted monthly to the Institute of Ocean Sciences at Pat Bay. This link provides the seawater récords for past months .

One of the ecotourism boats passed by while we were there . In a past agreement made with the ecotourism companies and BC Parks, boats are required to stay in the centre of the channel in order to comply with regulations for marine mammal viewing .

 

I noticed that the concrete and wood refuse left in piles from previous construction and repair work that was supposed to be taken off the island by a BC Parks vessel are still there after many reminders by Pearson College staff.

Progne subus: Purple martin – The Race Rocks Taxonomy

Posted on by

On June 20, 2045 , Race Rocks Ecoguardian Christine Chourmouzis found a purple martin in her house

she writes in her log: 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! 

 

  • Purple martins suffered a severe population crash in the 20th century widely linked to the release and spread of European starlings in North America. European starlings and house sparrows compete with martins for nest cavities. Where purple martins once gathered in the thousands, by the 1980s they had all but disappeared. (Wikipedia)

They have excellent aerodynamic  maneuvering control as they fly quickly over open areas catching insects with a wide opening mouth. They are valued for their voracious appetite for mosquitoes and flies. With their food being flying insects, the island certainly provides an abundant supply of the kelp fly Coelopa vanduzeei

Domain: Eukarya
Kingdom: Animalia
Phylum: Chordata
Sub-phylum: Vertebrata
Class: Aves
Order: Passeriformes
Family: Hirundinidae
Genus:Progne 
Species: subis. (Linnaeus, 1758)
Common Name: Purple martin

Physical Description:

 It is the largest swallow in North America. 
With an average length of 20 cm (7.9 in) and a wingspan of up to 38 cm (15 in), the purple martin is the largest amongst the 90 odd species in the family Hirundinidae.[9]
Purple martins are sexually dimorphic. Adult males are entirely black with a glossy steel blue sheen, the only swallow in North America with such coloration. Adult females are dark on top with some steel blue sheen, and lighter underparts. Adults have a slightly forked tail.

Relationship with humans:

Continual maintenance and protection is required, as European starlings and house sparrows compete with martins as cavity-nesters, and will fight with martins over nest sites. Thus, unmonitored purple martin houses are often overtaken by more aggressive, non-native species.[3] Purple martin proponents are motivated by the concern that the purple martin would likely vanish from eastern North America were it not for this assistance.[24]( Wikipedia)

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 .

 

 

Race Rocks Ecological Reserve #97 warden’s report April 2024

Posted on by

For the past few weeks a former biology student whom I taught at Pearson College, Jerremy Prassl has been serving as the Ecoguardian at Race Rocks. He would be leaving on April 5 and returning to Britain where he is a professor at Oxford.

I got a ride out on Second Nature with Greg and we also took out two bird observers from the Rocky Point Bird Observatory ( RPBO) / BC Nature Gull survey, Andrew Jacobs and James Kennerley. The detailed observations and a link to the identification of the interspecific gull hybrids eBird Canada Checklist – 3 Apr 2024 – Race Rocks – 16 species (+2 other taxa) was a valuable addition to research in the Ecological Reserve. Below is a sample from Andrew’s photos on eBird of their identification of the different gulls:

 

One project that needs to be done is a more permanent placement of stakes to hold the electric fencing which keeps the sea lions from damaging the vegetation and infrastructure on the island.

In my walk around the island I noted several areas that need attention, BC parks indicated several years ago that they would be out to remove several piles of construction waste. I think this has gone on too long and these piles are very unsightly and an intrusion into the ecosystem. Perhaps a reminder will elicit some action.
