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)

killdeer: 4
western sandpiper: 3
barn swallow: 3

Photo highlights from the past three days:

August 12 and 13

Two new visitors, Carl and Brady Hughes came to Race Rocks on Friday. They will be put into service helping clean solar panels, windows and decks. Carl will also assist with bird reports and attempt to record night-flying migrants passing over the island.

Ecological Notes:

  • Increasing numbers of California Gulls around the island. This smaller gull doesn’t tend to intermingle with the nesting Glaucous-winged Gulls very much.
  • Passerines seen in the last two days were Brown-headed Cowbird and Barn Swallow.  Readers are reminded that Race Rocks is an eBird hotspot and more detailed updates on bird sightings can be found at Race Rocks, Capital District, BC, CA – eBird Hotspot
  • 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.
  • See photos below for more ecological sightings.

Census July 6

Ecological Notes:

  • I am seeing more gull chicks everyday. Many gull parents are frequently feeding their two or three chicks.
  • I seem to have come to an understanding with some gulls. If I approach near them on the path at a slow speed, we both ignore each other. There are other gulls who freak out if I even look in their direction. As I do necessary work, I limit my movements around the island and avoid certain paths that have nearby nests and chicks.
  • See photo gallery and captions for more details on the ecological happenings over the past two days.

August 24 – Weekly Census

Wind: W 4-19 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 10-15 NM
Sky: overcast, then clear from mid morning onwards
Temperature: 13-15 °C
Atmospheric CO2: 412.21 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Here are the numbers from today’s census:
30 steller sea lions
121 california sea lions
1 sea otter
167 harbour seals
1 bald eagle
2 pelagic cormorants
742 california gulls
518 glaucous-winged gulls

I was excited to see the fluffy head of the sea otter this afternoon. This morning when doing the census count from the top of the tower, I scanned the kelp but couldn’t see the otter.

This afternoon, I gave TLC to the boat house, boat and boat dolly.

There was a steady stream of about two or three eco tour or pleasure boats per hour passing through the ecological reserve.

Here are some sights from around Race Rocks today:

Bustling Wildlife

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).

The numbers of sea lions continues to be low. For the first time this winter, there were more steller than california sea lions in the ecological reserve.

For the past day, the elephant seals have all been stationary. An elephant seal was seen on Middle Rocks today along with california sea lions. I believe it’s the smaller adult male that was on the main island until recently.

Having heard the killdeer on many evenings this winter, but not seen any, I finally saw one this morning on the lawn. They are named for their shrill repetitive call which sounds like “kill-deer!”

Here are the results from the weekly census observed on Friday, February 28:
7 elephant seals (4 adult males, 2 female pups, 1 male pup)
54 steller sea lions
53 california sea lions
86 harbour seals
5 bald eagles (2 adults, 3 juveniles)
26 Canada geese
9 brandt’s cormorants
10 double-crested cormorants
31 pelagic cormorants
72 gulls (mostly thayer’s)
8 black oystercatchers
66 pigeon guillemots
17 harlequin ducks
1 killdeer
15 black turnstones
6 surfbirds
1 fox sparrow

Yesterday, Greg, Alex, Warren and Cole were on the island to do maintenance on the desalinator and batteries. Two tour boats were seen in the ecological reserve each day. This afternoon, the RCM SAR boat from Sooke drove around the main island and the crew took photos.
