Compost project was completed on Saturday, with incorporation of a barrel of rain/fog water from the roof as the final touch. The rainwater was heavily contaminated with gull droppings, so not useful for much, but excellent to keep the compost moist and provide nutrients. The number and aroma of sea lions is increasing, but bird diversity remains low.

Ecological Notes:

  • Only the alpha male and one young female elephant seal were seen present in the last couple of days.  The male remained in his spot alongside the science house until mid-day Sunday. One of the young females made her way to that spot Sunday morning, and was still in place at sunset.
  • Only passerines seen in the last two days were Brown-headed Cowbird.
  • Another branded Steller’s sea lion (431Y) was seen. He was branded at Rogue Reef, Oregon in Jul 2013, and had not been reported since 2014. (Although some data is still pending.
  • Birders touring the area on Sunday found a single Common Tern, rare for this area.
  • A Short-billed Dowitcher was on East Beach on Sunday.
  • The aroma from the California sea lions and resulting flies are increasing. All  California sea lions have remained outside the fence–so far.
  • See photos below for more ecological sightings.

The compost rejuvenation project is almost complete! The first chamber was completely emptied with the compost spread to various locations, but mainly in the hollow along the main path to the Ecoguardian’s residence. The compost still in process from the second chamber was put into the first chamber, then topped with some completed compost which can be used to cover any new materials added.  Compost from the second chamber was used to fill some voids around both residences, although it was not all used up. There remains about 1/3 of the mature compost, piled up for future removal or to cover new compostable materials. The final steps are to reattach the boards and maybe one more little thing…

Ecological Notes:

  • All three elephant seals were seen on August 18. One of the young females followed the alpha male all the way to his usual place alongside the researcher residence.  She stayed with him for about 5 hours before returning on her own to the ramp.
  • Only passerines seen in the last two days were Brown-headed Cowbird.
  • The branded California sea lion (X759) seen Wednesday originates from Astoria, Oregon. He was branded in Feb 2017 and had not been reported away from that site after March 2017.
  • A Sooty Shearwater was seen south  of Race Rocks on Friday.
  • At least one Ruddy Turnstone remains.
  • Very quiet on the water over the last two days.
  • See photos below for more ecological sightings.

  • Two Ruddy Turnstones continue to be seen.
  • Sea lion numbers continue to climb. A branded Steller’s sea lion (183R) was seen on the north rocks near the jetty.  Information is being sought and updates will be provided.
  • Whale action picked up on Saturday, Aug 13 with multiple sightings of humpbacks and Orca.
  • Low tides continue to expose the intertidal areas in the early morning.
  • Only one young elephant seal was seen on Aug 12 and none on Aug 13. The alpha male continues on the island, often resting near the researcher residence.

Ecological Notes:

  • First sighting of Ollie the sea otter since I arrived. His new favourite location is in the kelp east of Great Race. I had seen him there on a boat trip on Aug 1.
  • First on-land passerines of my stay seen on Thursday, Aug 11: two juvenile Brown-headed Cowbirds. It is possible the bird I saw in the fog last week could have been one of these.
  • Sea lion numbers continue to climb.
  • Whale action must be in the Gulf Islands/San Juans, as fewer whale watching boats are coming this way.
  • Most of the young gulls are busy testing their wings, especially when the wind comes up.
  • Very low tides have revealed the eel grass beds and normally hidden intertidal zone.
  • See photos below for more ecological sightings.

Erysimum X cherei: wall flower– Race Rocks Taxonomy

Posted on by


Wallflowers were planted in the early years along the sidewalks by the lightkeepers. They still exist and in a mild winter, you can find them blooming on the island.

There are some interesting interactions that repel predator species which I have reproduced here from Wikipedia.

Defensive compounds

[edit]

Like most Brassicaceae, species in the genus Erysimum produce glucosinolates as defensive compounds.[16][17] However, unlike almost all other genera in the Brassicaceae, Erysimum also accumulates cardiac glycosides, another class of phytochemicals with an ecological importance in insect defense.[18][19] Cardiac glycosides specifically function to prevent insect herbivory[20] and/or oviposition[21] by blocking ion channel function in muscle cells.[22] These chemicals are toxic enough to deter generalist,[23] and even some specialist[24] insect herbivores. Cardiac glycoside production is widespread in Erysimum, with at least 48 species in the genus containing these compounds.[19][25] Accumulation of cardiac glycosides in Erysimum crepidifolium, but not other tested species, is induced by treatment with jasmonic acid and methyl jasmonate,[26][25] endogenous elicitors of chemical defenses in many plant species.[27] Molecular phylogenetic analysis indicates that Erysimum diversification from other Brassicaceae species that do not produce cardiac glycosides began in the Pliocene (2.33–5.2 million years ago),[28][1] suggesting relatively recent evolution of cardiac glycosides as a defensive trait in this genus.

First Elephant Seal Pup of the Season!

Posted on by

It’s that magical time of year where the Northern Elephant Seals come ashore and give birth! Our first mom is the same female who showed up first last year, Pink Tag 2 (who we affectionately call Bev), who came ashore on December 15th. After several days of being sassy and pregnant she gave birth to a new male pup on December 21st.

Bev seems to have a purposeful strategy showing up and birthing before the other females. Last season Bev showed up almost a month before the other moms, and left before the other moms were even getting ready to birth. By this time her pup was pretty huge and mobile. She gave birth last year on December 22 2020, so pretty much on schedule with what she did last year.

One of the first big hurdles for newborn pups is just figuring out just how to nurse, some pups take days to figure this out, but not this first pup: he was nursing within hours of being born is already looking plumper than when he was born.

Ecological Notes:

  • 1 Female Elephant Seal
  • 1 Male Elephant Seal, appears to be last year’s Beachmaster
  • First time I’ve personally noticed this type of tag …. On the Female Elephant Seal

Tag with holes in a pattern

 

harlequin ducks

Facility Work:

  • Cleaning and firewood prep for the next Ecoguardians
  • Looks like tomorrow morning will be all about clearing the pier area of debris and redoing the electric fence. The swells and incoming wind knocked concrete blocks right off the pier.

DND events:

  • 2 days of blasting with noticeable reactions from the Scea Lions.

Noted Vessel Traffic:

  • 3 different Ecotourism vessels
  • Several Sailboats back and forth, cutting between the reserve and Bentinck Island

 Feature Event:

  • Took a few Pictures from the top of the light while I was doing the animal Census.

 

Weather Events:

  • Mostly average winds from the west. Wednesday greeted us with 30-40 knot southeasterly wind, with very large swells!

A busy week!

Posted on by

Really hit the ground running this time! Many things going on at the same time, as well as getting myself re situated in the ecological reserve!

Ecological Notes:

  • California Sealions taking over any area available to them. The Steller Sealions pretty much keep to the outer edges and off-island rocks

    California Sealions wanting to hold their ground

  • Now  4 Elephant Seals working their way up the ramp towards the grass area. Looks like an almost mature Male, a fully mature female, and 2 sub-adults. They’re all a little timid, so I’m giving them lots of space.

3 Elephant Seals, just before the male showed up (the sealions are not impressed)

  • Also 1 large male I can hear frequently but can’t find, (maybe he is staying in the water and circling the island as he bellows in the evening.)

Visitors:

  • Various contractors working on replacing windows.

Facility Work:

  • Window replacements on the main house, and soon proceeding to the student building as well.
  • New toilet in the student building!
  • New electric fencing from the power building, around past the outside of the lighthouse, then back to the corner of the main house. Really important as there were up to 300 California Sealions between the student house and the lighthouse, totally blocking off access to the power building (until they were persuaded to leave, but would return the minute the coast was clear)

Noted Vessel Traffic:

  • Many Ecotourism vessels and private vessels enjoying the sights, sounds, and smells of the Race Rocks Ecological Reserve this time of year.

 Feature Event:

  •  Canadian Coast Guard checked in with us, as they kept a watchful eye on the smoke level and direction from the freighter at Constance Bank that had a fire in some of it’s containers.

Weather Events:

  • A varied week, ending in 2 days of stormy weather with strong winds (up to 50 Knots), and swells from the southeast.
