Early Spring Cleaning

Posted on by

Ecological Notes:

  • Still waiting to see if any Elephant Seals show up for the moult season
  • Sea Lion numbers are down a bit and not fluctuating as they have been
  • Transient Orca have been in the reserve 3 times at least over the last few days. they hunted right off the end of the pier, and in the channel just south of the light

Visitors:

  • Shore Front coordinator delivering supplies and fuel

Facility Work:

  • There was water in the basement of the Student and Science Center, and I first I couldn’t find the source. I checked all the plumbing on that side of the room, and mopped up the water. Checked a couple hours later and there was as much water there again. Realize it must be a new leak, and that it was still going. Took longer than it should have to find the leak, as it was working around the lowest points and looked like it was coming from the other direction. Isolated the problem, and repairs will be done tomorrow

  • With warmer weather and less rain, time to start spring cleaning of sidewalks. The algae cleaner needs the temperature, and rain free days to work.
  • Catching back up on fuel deliveries allows the replenishing of the Gerry Cans in reserve.

  • Noticed the fog horn wasn’t working on Sunday during the heavy fog. Coastguard notified so they could put out a notice to mariners. they have scheduled a visit for Thursday to repair it. With current availability of GPS and Radar on vessels, glad I didn’t have to use the manual back up!

  • Checking smoke detectors and first aid supplies that may expired

  • Awaiting new materials for the pier fence, cleaned up old wiring, saving longer pieces for repairs and making gates

DND events:

  • Detonations during the last week, under the guidence supplied by the Marin Mammal Observers on the water.

Noted Vessel Traffic:

  • Still a few Eco-Tourism vessels coming through.
  • 3 or 4 private vessels as well, all appropriate behavior

Weather Events:

  • Wednesday January 31:
    • Sky: High overcast with occasional sunny breaks
    • Wind: ESE to 30kts early, rotating through to NE 10-15kts during the day
    • Sea: rippled, some standing waves due to wind/tide combinations
    • Temperature Low 10oC, High 13.5oC
  • Tuesday January 30:High overcast, occasional brief rain

    • Wind: NE dropping to 0kts at sunrise, raising through the day to NE 25kts, then dropping again in the evening
    • Sea:  light chop
    • Temperature Low 10oC, High 14oC
  • Monday January 29:
    • Sky: Dense fog all day

DND Blasting:
There was one DND blast at 14:05 on July 12 at nearby Rocky Point.

Visitors:
Greg and Bruce visited this afternoon to deliver 1,400 L of freshwater and a new first aid kit.

Maintenance:
I did the routine tasks of cleaning the solar panels and house windows, topping up the water in the 24 deep cycle batteries, fixing the electric fence, tidying, and maintaining the freshwater system.

Ecological notes:
There have been a lot of humpback whale activity over the past few days to the west, south, and east of Race Rocks. The whale watching boats have been active in the area. From what I hear on the VHF radio, they have been very pleased with the humpback viewing. I have not seen any whales swim through the ecological reserve.

I heard back about the tagged elephant seal, from the researcher at Año Nuevo Natural Reserve, in California. The juvenile seal, tagged H999 and K646, is a male who was born in January 2022. He was previously observed here and reported to the researchers on April 1, 2023. He has been moulting here for at least the past several weeks. He appears to be almost complete the moulting process, so he might be moving on soon to feed in the deep waters.

Weekly Census observed on July 13:
elephant seal: 1 juvenile (tagged H999, K646)
Steller sea lion: 3
harbour seal: 79
bald eagle: 2 adults, 1 juvenile
raven: 1
cormorant: 7
black oystercatcher: 6 adults, 1 chick (that I could spot today)
pigeon guillemot: 148
glaucous-winged gull: 387 adults, 120 chicks
surfbird: 12
killdeer: 4
western sandpiper: 3
barn swallow: 3

Don’t trust the weather report

Morning visitors

Weather: SUN! westerly wind 16 knots. Sparkling water.

Visitors: Several whale watching boats. All came close to the seal lions on the jetty but they didn’t disturb them. Fishers outside reserve area.

Work: cleaned solar panels. chopped wood. cleaned windows (on the inside) in lamp room.

 

Energy: Every morning it is a bit of guess work to see  if I can hold off using the generator. Particularly today when it called for clouds and rain. I was happy the first hour of potential solar energy boosted the batteries to over 50 volts. Then I had some breathing room. I tend to look at the numbers often and try to see how I can avoid the generator or use it as little as possible. Not listening to the forecast can be useful!

Observations: Gulls are beautiful. They are so easy to take for granted but now that I am looking closely at them I see how exquisitely white they are. It is amazing to get to watch them go through their courtship. I don’t envy the few immature gulls on the island. If they try to land anywhere near the centre of the island they are quickly reminded that this is a breeding colony and they are not welcome.

Several sea lions have taken to lying on the steps of the jetty. The new electric fence keeps them from coming right up. I feel somewhat sad about this, thinking that for years they have returned and sandwiched themselves on that cement surface. We had to move them off every day to take water samples so it wasn’t an absolutely ideal life. I just wonder how often they need to get zapped to stay away and if there is anywhere nearly as comfortable.

It fascinates me that I can’t get near the nesting Canada geese. I make big detours to avoid the nest and therefore avoid getting attacked and yet the several hundred pound mammals prove no obstacle. They will readily move when I need to take a water sample.

The 6 female elephant seals have split into 2 groups (by size it seems) and life is peaceful for them. Only a few days ago there was lots of conflict. They haven’t left the island today and the male pup has not returned. They have mostly moulted it seems and are waiting for their new fur to grow.

After I wrote this I saw the sea otter! He was around seal rocks for a couple of hours.

A Wonderful Windy Weather Day

Posted on by

sunrise and fog

Weather: The morning sunrise was behind fog. It cleared up after an hour. Winds started as westerly. Beautiful sunny day charging the batteries to almost 100%. By 1800 hrs however a north wind started howling (24 knots)It has converted to a westerly as I write this, now at 29 knots. Very dramatic skies!

Visitors: several ecotourism boats, all slowed down and came close to the jetty to see the elephant seals.

Observations:  Besides the pictures below. There are currently 6 female elephant seals. The pup was not on the island all day. Brown-headed cowbird here all day.

Why do the geese eat this?

Mature Male Elephant Seal

Posted on by

Ecological Notes:

  • A new Adult Male Elephant Seal has been visiting the main ramp area for periods of time. While not quite as large as the Alpha and Beta males here last winter, this guy is pretty big!

  • The Sub-adult Male Elephant Seal, that was hauled out for a week or so last month, has been hauling out on middle rock.

Facility Work:

  • We got the Desalinator up and running! After changing the control panel, we re-checked and adjusted some settings and it’s working fine now.
  • Finished the new layout on the pier electric fence. As we had added a new, more powerful, fence energizer, many of the old wires and connectors were failing. Each Ecoguardian comes to Race Rocks with their own skillsets and ideas. This new idea will hopefully be more  sturdy, and easier to repair and maintain. ……. (but we’ll see!)

  • Received and assembled a new cart for the portable diesel tidytank. As the last one failed, will be adding an additional safety strap to this one for when someone has to move it by themself..

Noted Vessel Traffic:

  • Ecotourism vessels and private vessels have been visiting to enjoy the sights and sounds of Race Rocks.
  • A single paddler in an outrigger canoe also ventured out and through the main channel.

Weather Events:

  • Heavy rains over the weekend gave way to light fog on Monday. Westerly winds of 5 – 10 knots prevailed.

Maintenance and Repairs

Posted on by

Ecological Notes:

  • The younger Elephant Seals left after just a short visit. The adult female stayed and rested for about 4 days.

  • The sub-adult male is still onsite, nestling in the bushes in the center of the island. At one point, the contractors left the basement door open on the main house, and we caught the male bee-lining for the door! Luckily, he stopped once someone called out to him.

    As he slowly turned back towards his favorite spot by the tall bush.

  • Sealion numbers are down to about 1/3 since the big storms left (will do a count on Monday)

  • Many Black Turnstones present at this time.

    Many nestled in the rocks

Visitors:

  • Window Contractors, and deliveries by both Greg and Jeff.

Facility Work:

  • Almost continuous repairs and upgrades to electric fencing.

Sometimes it’s lucky and they just knock down the posts without damaging anything.

  • Collecting wood brought in by the storms.

Pulled up by hand and pipe pole!

  • I keep an eye on the Web Cams by checking them daily. A little water got in, and this happened!

 DND events:

  • Detonations most of the week, some very heavy ones. Marine Mammal Observers were on the water, keeping an eye out for cetaceans. Noted sealion disturbance, they have seemed to be very edgy since the storms subsided.

Noted Vessel Traffic:

  • Mostly just daily visits from Ecotourism operators, and a couple private vessels, also primarily looking at the birds and wildlife.

Weather Events:

  • Variable weather, medium winds and rain showers.

Time for fencing

Posted on by

 

Personal Note:

  • On my last day here at the Race Rocks Ecological Reserve, I’m very thankful for the opportunity and experience provided to me. My normal employment calls me back, but I hope to return to continue experiencing the reserve in a different season!

Ecological Notes:

  • 1 Male Elephant Seal and one Female Elephant seal in the grass area up by the power building

    Enjoying the sun

  • Although I’m sure there are more, I caught a quick glimpse of some Pigeon Guillemot chicks as they scurried back into their rock den.

Facility Work:

  • Existing electrical fence routes redone and repaired. The north field had all the fencing replaced, and a couple new gates added. A new section will be added to the south (lighthouse side) when supplies are available. As the sealions start to return, fencing plays an important roll in protecting the plant life, and structures and equipment on the island. There is also a huge safety factor for the Ecoguardians when moving around accomplishing their daily tasks.
  • Although not a pleasant topic, removed 2 old Sealion carcasses  from high above the waterline. The warmer weather really increased the smell, but the wind and heat (and bugs)  really help them to break down to an almost manageable weight for dragging. Respectably returned to the ocean.

DND events:

  • 6 to 10 detonations over Monday and Tuesday, all sealions moved from the middle rocks to the southern rocks.

Noted Vessel Traffic:

  • Several Ecotourism vessels and at least 6 private vessels sightseeing in the reserve.

 Feature Event:

  •  Lots of  cleaning and organizing in preparation for the new Ecoguardian arriving Thursday! A warm welcome to Sierra!

Enjoying the sun

Posted on by

Ecological Notes:

  • 4 Elephant Seals still in the grassy area
  • I’ve been watching an interesting behavior of one of the female Elephant Seals but can only speculate on the reason…. She has spent 3 days in the very thick Pineapple Weed. This plant produces as very sweet smell when crushed. Every time she wakes up, she moves forward, then thrashes about and slams her head into the fresh patch. She breaths deeply for a while, and falls back asleep!

Crushed trails

nestled in for a sleep

Facility Work:

  • After confirming the need last week, and insuring the system was working properly, it was time to do some minor repairs and modifications to the pier electric fence. Sunlight, salt water, waves and animals can be hard on electricals!

Weather Events:

  • Westerly winds of 20-30 knots all day. Large swell and chop until midday when the tide turned to a flood, which smoothed thing out a lot. Sunny with  light haze at water level, but still pretty good visibility.

Oyster Catcher Nest Sites

Posted on by

Ecological Notes:

  • 7 Elephant seals between the grass and the boat ramp. It appears another female may have left the reserve. Still 2 “pups” here. (included in the 7 total)
  • The pups are definitely using up their baby fat, and showing lots of wrinkles. The male is still molting though.

    When he finishes molting, he can head off to feed.

  • Have now verified 4 Black Oyster Catcher nests (able to view the nest from good vantage points in the distance). Quite confident in at least 2 more from the bird behavior, but no good distant vantage point to confirm, and don’t want to disturb the birds.

Visitors:

  • EagleWing Tours provided  Pearson College Students with 1 hour tour of the reserve and surrounding area (water based only). Total of 34 Students.
  • Between student tours, 2 employees of EagleWing Tours were brought to the main island by the waterfront coordinator for a visit.
  • The Waterfront Coordinator also delivered groceries, drinking water and electric fence supplies

 Facility Work:

  • Repairs and alterations to the electric fence on the main pier. This is important not only for the safety of the facility and the heritage sites, but also for the safety of the Sealions themselves. If they come up the top of the pier and are startled from their sleep (by land, or boats in the water), they run the risk of jumping over the side from a high height, into shallow water. Generally, on a natural rock face, steeper slopes continue into deeper water.

Noted Vessel Traffic:

  •  2 Ecotourism vessels, 1 commercial Dive Tour operator. All with proper viewing and usage procedures.

Good behavior in the reserve! (some compression from the distance and my lens, NOT as close to the rock as it may appear!

  • 3 Private vessels, all with good approach and viewing.

 Noted Infractions:

  • The most common error, generally speaking, is that private vessels tend to power up too early on departure from the reserve.

Again, some compression effect from my lens, but this private boat had come up to speed even earlier than this, well within the reserve.

Weather Events:

  • Mostly clear with westerly winds at 15 knots most of the day. Westerly winds increased to 25 – 30 knots in the evening, bringing in some haze and clouds.

April 1 and 2

Posted on by

Wind: yesterday variable 1-21 knots, today W 2-31 knots
Sea State: both days rippled
Visibility: both days 10-15 NM
Sky: both days partly cloudy then clearing in the mid morning
Temperature: yesterday 4-10 °C, today 5-6 °C
Atmospheric CO2: 415.81 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday morning, a new elephant seal arrived on the island. He has green tags on each tail flipper, D018 and D019. The green tags signify it was tagged at Año Nuevo Reserve, similar to the female juvenile seal here right now. Due to the website being down for a few days, I didn’t realize at the time the seal was the same one here for the last two weeks of December. The seal was also seen here for two weeks in April 2019. I reported the sighting to Dr. Patrick Robinson, the Director of Año Nuevo Reserve, near San Francisco in California. He reported back that the seal was born at the beginning of 2017, meaning he is now a three year old sub adult. Based on the photos I sent Dr. Robinson and included in the gallery below, he determined the seal is in great body condition but fur/skin is in poor condition.

In the past few days, the sea lions have been taking over the jetty, something they haven’t done in critical mass since the beginning of the winter. This afternoon, I finished setting up and testing the electric fence on the jetty to deter sea lions from congregating and damaging the railings and boat cleats. When I need to use the jetty to test the seawater or for boats, the sea lions need to be cleared off. No matter how slowly I approach the them, they only have one speed of getting off the jetty, which is stampede. It will take some time each day to maintain the fence from sea lions bumping it, as well as wind and waves.

Only one boat was seen in the ecological reserve, a Coast Guard rigid hull inflatable went through Middle Channel yesterday afternoon and stopped to take photos of sea lions on the rocks.
