First Official Day On The Job

After training last weekend, and a general review yesterday, I, Riley Strother, have now taken over as Ecoguardian from Alex Fletcher.

Weather

  • Visibility: 15 miles
  • Wind: 15-20 knots NE
  • Water: 1’ chop
  • Sky: overcast

  • The first female elephant seal to give birth left the island at 7:30 in the morning and did not return. As such the first pup has now become a weaner.
  • Chunk appeared to mate with the female who lost her pup.
  • The newest pup is quite vocal and seems to be doing well. Chunk and the other female went along the path after mating to inspect the new mother and pup.
  • Alex was able to identify the number on the yellow flipper tag attached to the newest mother: 5928
  • There was quite a disturbance of seagulls and cormorants today when a raven with a small fish in its beak was chased all around the island by two eagles. Eventually the raven managed to land and eat the fish.
  • Conducted a census.
  1. California Sea Lions: 88
  2. Northern/Stellar Sea Lions: 53 (many sea lions were swimming in the waves and thus impossible to count)
  3. Elephant Seals: 8 (Chunk, weaner, grieving mother, new mum and pup, Middle Rock: Chuckles, mum and pup.)

  12. Canada Geese: 6
  13. Black Turnstones: 29

Maintenance

  • Cleared logs off the ramp two times.
  • Lowered the boat trailer because the cable coil was quite criss crossed. Managed to recoil the cable in a more orderly fashion.
  • Vacuumed up hundreds of fruit flies in the basement near the composting toilet.

Boats

  • Alex and Virginie left in the morning.
  • Surprised to see no eco-tourism boats about on such a nice Sunday.

Gust, Swell and Rain

Ecological Happenings

  • Animals continue to shift around the island and surrounding rocks, adjusting to the weather and moving away from the swell.
  • Number of geese on the island increased significantly from 13 to at least 48 today.
  • A necklaced Sea Lion spotted today near the dock.

Marine Vessels

  • Three tour boats
  • Two pleasure vessels

Maintenance

It was a beautiful day at Race Rocks, with light southeast winds and a mostly clear sky. The barometer fell a little today to ~1013hPA and the forecast for tomorrow is for sunny skies. There is a strong wind warning in effect for overnight with diminishing southeast winds Friday. Rain is forecast for Saturday.

Only four whale-watching vessels were noted in the protected area today and three pleasure craft passed through going slowly. The people on one of those vessels, the Kaos were observed feeding rockfish to sea lions in the Ecological Reserve. It is illegal to feed wildlife and if it happens they will be reported.

Today was animal census day and here are the results.

Don and Nina, the new eco-guardians in-training arrived today. They worked hard all day, after getting up very early to catch the morning slack and are progressing really well in learning some of the idiosyncrasies of Race Rocks operations.

Steaming Up the Strait?

After an overcast and partially foggy start to the day, the sky cleared in the early afternoon. Winds were less than 10 knots all day from the west-southwest turning to east in the evening. The barometer rose slowly all day and reached ~ 2022h PA. The forecast is for light winds becoming easterly 10 to 15 knots early Wednesday morning. It is expected to clear in the morning and be nice on Thursday.

Only four whale watching vessels were observed in the protected area today. They all treated the protected area with respect and drove slowly and carefully. Several pleasure craft went through, one at high speed, right through the area where there were 50 to 100 sea lions in the water. The other sports fishers were much more careful.

A couple of miles to the south of Great Race, a Canadian sub was observed heading out to sea and then a few minutes later, literally steaming back to shore.

I had the opportunity to work with one of Catrin Brown’s first year biology students today. They have just finished studying ecology, so came well armed with vocabulary and concepts and were keen to soak up knowledge gained firsthand on this little biological hot-spot.

We saw evidence of food chains and food webs everywhere from Canada Geese grazing on the grass, to evidence of predation on gulls and predation by gulls. We observed the thick climax kelp forest that rings the islands and reefs and saw evidence of intertidal grazers like chitons and phytoplankton feeders like clams and mussels. We didn’t spot the sea otter that is usually here but had plenty of other marine mammals and evidence of their dining and moulting habits in the form of fish bones, fish otoliths and hair, fur and pelage (from the spring moult of the Northern Elephant Seals).

We talked about the trophic level of different types of Killer Whales and the need for protection of critical habitat for recovering species at risk. The southern Resident Killer whales are of course highly endangered and are really dependent on strong Chinook Salmon runs while Biggs Killer Whales feed one trophic level up and eat marine mammals like seals and sea lions that in turn eat salmon.

We talked about the timing of births, mating, nursing and parental care in different species and about different symbioses including parasitism ( nice worms present in seal poop) and mutualism. We talked about phenology and seasons being dominated by different types of fish and about migrations.

We even touched on the great detritivore and decomposition loops. The carbon sink that is mediated by the microbial pump that transfers carbon to deep sediments. It was an ecologist’s kind of an afternoon, a living show and tell, a time for discovery and questioning which will hopefully on reflection, lead to some deep learning.

Chores were routine and it is great to have company.

Twofold Foggy: Friday – Saturday

Friday started with fog again and light southeast winds, from 5 to 10 knots. By late morning there were glimmers of clearing and by mid-day the sun was shining. The wind stayed calm and it stayed fairly clear, with clouds rolling by as the wind turned to west, in the late afternoon. By evening it was still and the sky mostly clear but that must have changed as the was fresh rainwater in the morning. The barometer bottomed out Friday morning at 1007 hPA before rising briefly. It started to drop again mid-day falling until mid-Saturday. The gale warning for Saturday, came true after another very foggy morning and light easterly winds. The turn to westerly was rapid, the fog was blown off and ominous clouds with a black line on the water to the west, foretold of what was to come. It blew up fast, reaching 40 knots and then settled back down to the up and down of 20 – 35 knots. There is gale warning is still in effect and the wind is forecast to lighten overnight, then become easterly 5 to 15 near noon Sunday. (I am collecting rainwater for laundry, bonus.)

Only two whale watching vessels were observed in the protected area Friday. Two sports fishing vessels also passed through. Saturday was a little busier with five whale watching vessels noted in reserve but there were no pleasure craft, they were probably seeking shelter. It is quite possible that I missed traffic both days due to thick fog reducing visibility.

Thursday was too foggy to do the animal census so it is cobbled together from the brief time slots when visibility permitted on Friday. It is interesting to note that the gull population plummeted after the arrival of the first Bald Eagle to be seen here, since I arrived at the end of August. Not sure if that is coincidental or not.

I only noticed the eagle because of the hundreds and hundreds of gulls moving en masse, from North Rock over to Great Race. When I peeked through the spotting scope, all the cormorants were in the water, the gulls were gone and there sat an adult Bald Eagle. Only the Harbour Seals seemed to ignore its presence.

There was no sign of the eagle today and the gull numbers are perhaps even lower. Glaucous-winged juveniles and adults continue to mill around summer territories. Some young ones are still practising picking things up, flying up and dropping them. Most of the adults are fully into their alternate plumage now. Their faces recovering from the physical aspects of feeding young.

The sea lions are spending more time in the water now that their favourite haul-out spots are worse than pig pens. Some of them have turned to rock climbing and I saw the first scouts up on the heli-pad today.

Starting the countdown on my last week on the rock for this shift. I may be back for a bit at the end of October, if extra training is needed for the new folks.

Hotel California

It was a glorious October day with sunshine and light southeast winds. The barometer slid down to almost 1015 hPA but the forecast looks good with more light winds and sunshine.

Only two whale watching tour boats were observed visiting the Ecological Reserve today. Several ‘pleasure’ craft came through and only one speeder was observed, two young men in a rental boat.

There are more and more California Sea Lions and they are damaging the burial cairns and the area above the boat shed where the rare plants used to live. Where ever they haul-out for more than a few days becomes quickly burnt looking and devoid of vegetation. Today they knocked down a big boulder from above the boat house onto the walkway. The Canada Geese have returned as well and are stubborn about staying so it feels like an invasion. The Stellers Sea Lion numbers are staying steady and individually they seem much wiser and wilder than the California party lions. The Northern Elephant Seals sleep amongst the Californians and are much less reactive than either of the two sea lion species.

Chores were all about fighting entropy today. The sunshine was a bonus for power generation and making fresh water. There were no visitors.

Gathering of the Gulls

Today started fairly clear, then clouded over. In the afternoon it was sunny for a few hours and eventually the sky darkened and at dusk the rain started. The barometer rose to almost 1019 hPA mid-day and then fell. The forecast is for clearing and light east winds with sunshine on the horizon.

Twelve commercial whale-watching vessels were observed working in the Ecological Reserve. They were in the area watching a Humpback feeding very close to the western reserve boundary, transient orcas to the southwest and southern resident killer whales to the northeast.

Today was census day due to thick fog yesterday.
