Sunny Day + Census

Posted on by

Weather:

  • Visibility 15 NM
  • Sky partly cloudy
  • Wind 0-5 knots N
  • Sea state calm

Boats/Visitors: None

Ecological:

  • Yesterday we saw a humpback whale pass through the straight roughly 1 NM away. Notably, this is only the second time that we have spotted a whale from Race Rocks without tourism vessels following close behind.
  • Not seen today in our census, there have been many black turnstones in the reserve this week (at least 10 at once).
  • Early this week we spotted what looked like a non-breeding adult willet. It seems as if it would be unusual to see one here so we are unsure if this is the correct ID. Without a photo it’s hard to be sure!

Census:

  • 9 elephant seals
  • 180 seagulls
  • 134 harbor seals
  • 112 sea lions
  • 11 cormorants
  • 6 oyster catchers
  • 2 adult bald eagles
  • The last pup left has been moving around the island, here it rests near the generator building.
  • Sea lions resting on an outcropping rock
  • We’ve been seeing these eagles around nearly every day.
  • The goose count rises, and so does the time we spend cleaning up after them!
  • Geese aggressively protecting their nest area
  • The invasion begins, slowly at first…

Windy Weekend

Posted on by

Weather:

  • Visibility 10 NM
  • Sky mostly clear, some clouds in late afternoon
  • Wind 15-25 knots N
  • Sea state: white caps, waves breaking at 1 m

Boats/Visitors: None

Ecological:

  • Things have remained uneventful over the weekend. The elephant seals have been settling in for windy weather and bickering quite a bit.
  • There have been two crows visiting off and on this week. They don’t usually stay very long and the other animals don’t seem to mind.
  • The youngest goose nest has two eggs today.
  • This nest has two eggs- the geese cover them when they leave the nest
  • Periwinkles in the intertidal
  • Remaining pup in her favorite spot
  • Stormy clouds moving in from the west
  • Today’s intertidal find: Abalone!

Business As Usual

Posted on by

Weather:

  • Visibility 15 NM
  • Sky partly cloudy
  • Wind 30-40 knots N
  • Sea state: white caps, fast moving water, waves and swells up to 1 m

Visitors/Boats:

  • There have been no visitors to the island and no boats within the reserve

Ecological:

  • There is a new goose nest with one egg so far established in the middle of the island where the footpaths intersect
  • The young pup has seemed particularly inactive recently, and we have not seen her in the water for some time. Nick mentioned to us when he visited that she seems to have gained weight so we are not overly concerned. She spends most of her time near the jetty behind her favorite fence post.
  • The goose with an injured leg continues to limp around the island, but seems to be making do and there are no signs of deteriorating condition.
  • The eagle activity has been steady, aside from today with these strong winds
  • The seagulls are beginning to pull the grass and collect other debris for nesting, but no established nests so far.

Maintenance:

  • The generator is still out of commission, but we have been taking in a substantial amount of solar energy. Combined with the smaller generator contributing, our batteries have remained healthy. We are conserving water heavily until the new part arrives, as the desalination process requires a sizable amount of electricity.
  • Felted sea lion fur
  • Goose down clinging to rocks
  • Abandoned goose nest behind fuel shed
  • E103, “Erica” enjoying the sprinkle from a punctured fire hose
  • Keeping the solar panels clean

Bustling Wildlife

Posted on by

Weather:

  • Visibility 10 NM this morning, 15+ NM this afternoon
  • Sky overcast in morning but clear this afternoon
  • Wind 20-30 knots NW-NE
  • Sea state: white caps (.25m), fast moving ripples

Visitors/Boats:

  • Greg and Nick on Monday
  • Greg and Nick on Tuesday
  • Greg and a technician for generator maintenance on Wednesday
  • Greg and Nick this afternoon (Thursday) 

Aside from this there have been very few vessels aside from commercial/shipping traffic. Today a couple of sailboats passed by despite the astounding wind gusts (all a fair distance away).

Ecological:

  • There have been 4 eagles in the reserve daily on average, both juvenile and adult. They typically perch on Rosedale Rock to our SE, but we have been spotting them on the webcam tower, crane, and diesel tank near the power building. The juvenile eagles seem to be more interested in Great Race Rock, while the adults tend to stick to the outcroppings. Occasionally they swoop over the reserve, prompting the seagulls to rise into the air to avoid becoming lunch!
  • The geese continue to protect their nests but no new eggs have been observed.
  • The elephant seals have settled to complete their moult, all in various stages. The remaining pup is still here, and spends most of its time on the jetty away from the others.
  • There is a sea lion with a significant head/neck wound that we have been seeing daily. It looks like it has been tagged by the Vancouver Aquarium, so we are wondering if it has been disentangled and tagged at the same time.
  • Yesterday we spotted a killdeer, a type of plover. We’ve never seen one here before!

Repairs/Maintenance:

  • We filled the underground cistern with sea water to be desalinated (pumped using the fire pump and fire hoses).
  • To maximize our solar intake we have been keeping the solar panels as clean as possible (when they are covered in bird waste they create much less power). 
  • Juvenile eagle on diesel tank
  • Juvenile eagle on power building
  • The gang
  • Moulting elephant seal skin and fur
  • The gulls continue to arrive for nesting…
  • … and defend their territory fiercely!
  • a breeding pair of geese resting
  • This one has a sore leg from a fight!
  • The youngest nest
  • Tag of the latest arrived elephant seal
  • Pigeon Guillemot
  • Sea lion with healing entanglement wound
  • Killdeer (adorable!)
  • Juvenile bald eagle perched on the crane

  • We spotted the HMCS Regina heading into Pedder Bay

Ecological:

  • We found another goose nest yesterday underneath the back steps of the main residence containing 8 eggs. We noticed that the nest near the desalination structure has been looted by seagulls and abandoned.
  • The seagulls continue to arrive and establish their nesting spots. There are roughly 50% more gulls this week.

First Days Back

Posted on by

We are happy to be back on Race Rocks surrounded by the animals again. A big thanks to Nick for leaving things in excellent shape!

Weather:

  • Visibility: 10+ NM (Victoria Clear)
  • Wind: 10-15 knots NW
  • Water calm
  • Sky overcast

Visitors/Boats:

  • No visitors to the island since we arrived on Wednesday
  • One whale watching vessel yesterday with three people on board
  • Three jet skis passed through on Thursday evening

Ecological:

  • There are 10 elephant seals resting outside of the house this morning
  • One is the last remaining pup, as pointed out by Nick
  • The map of Goose nests that Nick left for us remains accurate, but there are many new eggs.
  • The seagulls are beginning to arrive and fight over nesting spots. We have observed them beginning to pull up tufts of grass and lay them down for nesting.
  • Yesterday evening we noticed an entangled sea lion from the jetty. It appears to have a plastic packing strap wrapped around its neck, similar to the one that we saw last year.
  • There are two mature eagles that have been periodically swooping over the reserve, causing quite a stir.
  • There are at least two pairs of oyster catchers preparing to nest. Yesterday we saw the pair which nested near the guest house last year defending the same rocky area.

April 13 and 14 – End of Shift

Posted on by

Wind: yesterday variable 2-28 knots, today W 7-38 knots
Sea State: yesterday calm, today rippled in morning and up to 1 m chop in evening
Visibility: both days 15 NM
Sky: both days clear
Temperature: yesterday 7-13 °C, today 8-11 °C
Atmospheric CO2: 415.81 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Today is my last full day on the island before the shift changeover. Tomorrow morning, Mara and Kai will arrive to take over as Ecoguardians. They were here last year from May to September.

I spent the past two days finishing up some tasks around the island and cleaning. I also took time to walk around the island and get a look at all of the incredible species, land and shoreline that make up this ecological reserve.

There were no boats in the ecological reserve.

See the photos below for some views from around the island.

  • The combination of clear water and low tide make it easy to see lots of colourful seaweeds, surfgrass, urchins and other intertidal species.
  • Two swallows were fluttering around the island yesterday. This one landed on the a cable on the winch long enough for me to take a photo.
  • At first I thought it was barn swallows, but then with the help of a field guide realized it’s a violet-green swallow.
  • The sun peering over the horizon at 6:20 this morning.
  • The lighthouse just after sunrise this morning. The moon, in its third quarter, can be seen to the south.
  • A thayer’s gull with a Canada goose egg in its beak.
  • Can you spot the juvenile elephant seal in the middle of the photo, amongst the group of california sea lions?
  • A beautiful sunset on the edge, where the land meets the sea meets the sky.

Sea State: both days calm
Visibility: yesterday 10-15 NM, today 15 NM
Sky: yesterday partly cloudy then clear from mid morning, today clear

The lawn in front of the house got busier this morning with nine elephant seals, two more than yesterday. A tenth seal, the pup, was near the jetty. The two new arrivals have green tags on their tail flippers. One is a male tagged C887. The other is a juvenile tagged G512 on the right flipper and E779 on the right. I will update the information on age and past sightings when I hear back from the researchers. The green tags signify the elephant seals were tagged at Año Nuevo, south of San Francisco.

[UPDATED April 13: I heard back from Dr. Patrick Robinson, the researcher from Año Nuevo Reserve. The elephant seal with green tags E779 and G512 was tagged as a pup in February 2019, where he was born at Año Nuevo. This is the first time the male juvenile has been spotted outside of Año Nuevo, where he was last seen as a weaner in March, 2019. The elephant seal with the green tag C887 is a juvenile male that was born at Año Nuevo in February 2017. He has been seen at Race Rocks in the month of December in 2017, 2018 and 2019.]
