Ecological Notes:

  • I have spotted at least six oystercatcher chicks over the past four weeks, although they are hard to get photos of since they often hide and blend in with the rocks. The parents alert the chicks when I am nearby. On any census day in July, I have only been able to spot three each day. Today I spotted four.
  • I launched the station boat early this afternoon to pick up two volunteers from Pearson campus. On the way to and from Pedder Bay, I slowly and at a safe distance checked out some of the smaller islands that make up the ecological reserve. On the way back with the visitors, we went around the island clockwise to see the sea otter in the east kelp, around the south side of the island, through Middle Channel to see the hauled out sea lions, then landing at the jetty to many watching eyes on the eco tour boats and four elephant seals in the jetty bay.
  • The three juvenile elephant seals (two females and one male), who have been in the jetty bay and on the boat ramp over the past week, have been joined by a large male elephant seal. His huge size, as well as large proboscis (trunk) and back battle scars lead me to believe he is the alpha male I witnessed here in the winter and early spring of 2020. He has also been here as the alpha male for the past two winter birthing seasons. Some past ecoguardians referred to this alpha male as Bernard. I prefer not to anthropomorphize animals. I suspect the three juvenile seals are offspring of the adult male, as the alpha mates with all the females after they give birth. I also believe the juveniles might be the three pups born between December 2019 and January 2020, when I was on the island. They appear to be the correct size for two and a half year olds. They also seem to be friendly with each other as they were in the spring of 2020. See the comparison photo below :)

Ecological Notes:

  • Two humpback whales passed through Middle Channel, just north of the main island, yesterday morning.
  • Yesterday afternoon’s high of 27 oC was evident with many of the gulls panting in an effort to regulate their temperature.

July 23 and 24

Ecological Notes:

  • I am catching occasional glimpses of a humpback blows to the southeast and southwest of the island, although a bit too far away to see much detail.
  • I am still trying to live harmoniously with the gulls by avoiding the chicks as much as possible, while still keeping things running on the island. I have not been pooped on in at least a week, so either the adult gull’s aim is off or they do not see me as threat.
  • See the photo gallery below for more ecological happenings from the past two days.

Weather:

  • Yesterday (July 23):
    • Sky: Cloudy, then clearing mid-morning
    • Wind: W 11-31 kts
    • Sea: rippled, then up to 1′ chop in afternoon
    • Temperature Low 12 oC, High 14 oC
  • Today (July 24):
    • Sky: Fog overnight until late morning, then partly cloudy for remainder of day
    • Wind: W 3-23 kts
    • Sea: rippled
    • Temperature Low 11 oC, High 15 oC

Visitors:

  • No visitors

Facility Work:

  • Scrubbed and squeegeed solar panels, routine tidying and checking infrastructure around the island.
  • I ran the generator yesterday for its monthly equalization charge, which charges the batteries at a higher voltage to keep them healthy in the long run by balancing the voltage in each battery. The 24 batteries, each the size of four cinder blocks stacked up, are essential to maintaining constant power for the human life support systems on the island even when the solar array and generator are not supplying power.

Ecological Notes:

  • A pod of humpbacks is still spending time to the southwest of the island. I spotted several last evening from the kitchen window while I was doing dinner dishes.
  • There are now two female elephant seals near the boat ramp. They are similar size. The one who I first spotted today, has a bit lighter fur and more scars on her back, as compared to the other who has been around on and off for a few days.
  • I have seen about 50 dead gull chicks around the island. There could be more in the areas I can not see. A few of the chicks have been ripped apart by a bird. I am not sure if it was an eagle or gull. Most of the dead chicks do not have any obvious signs of death, they are just lying in the grass near nests.

July 19 and 20 – Weekly Census

Posted on by

Ecological Notes:

  • An elephant seal swam up to the boat ramp at some point yesterday late afternoon or evening. When I went to do the seawater sample at 19:30, I spotted her sleeping at the water’s edge. As far as I can tell, she has been there ever since.
  • See the photo gallery below for more ecological happenings from the past two days.

Weekly Census recorded on Wednesday, July 20:

It was not an ideal day to record the census, as it was quite foggy. Although, I had a window of less fog at around noon, when I could see all the islets that comprise Race Rocks and the water in between, so I was able to count the species from the lantern room of the lighthouse. I counted other species throughout the day as I walked around.

  • Black oystercatchers: 11 (8 adults, 3 chicks)
  • Cormorants: 5
  • Glaucous-winged gulls nesting on the main island: 229
  • Glaucous-winged gull chicks: approximately 250 (It is hard to get an exact number due to their camouflage in the grass and hiding under their parents) 
  • Gulls not nesting (some glaucous-winged and some other species) on the south end of the main island and outer islands: 96

July 17 and 18

Posted on by

Ecological Notes:

  • A large pod of humpbacks has been around Race Rocks for at least the past few days, with many visible to the south. Today, I saw a few blows and dorsal fins near north of Turbine Rocks (north of the main island), then near West Rocks. Unfortunately, I did not get any photos.
  • I keep seeing a fast moving barn swallow and fox sparrow fluttering low around the island. I only see one at a time, so it is possible there are more of each species. Similar to the humpbacks, the little birds don’t stop in one place long enough for a photo opportunity.
  • See the photo gallery below for more ecological happenings from the past two days.

 DND Events:

  • Between 10:20 and 13:20 today, there were three detonations on the nearby DND (Department of National Defence) training area on Bentinck Island, about 2km or 1NM from Great Race Rocks. The sudden explosions sent many birds into the air, as well as seals and sea lions into the water.

July 15 and 16 – A Scoop of Pelicans

Posted on by

Ecological Notes:

  • 12 brown pelicans flew around the island at 12:30 yesterday. They returned just before 14:00, flew by the South Islands, and landed on the South Seal Rocks. They moved to the east side of Race Rocks, where they remained for at least a couple hours. A group of pelicans is known as either a pod, pouch, scoop, squadron, or fleet.
  • The glaucous-winged gull chicks are growing quickly, with many meal deliveries happening throughout the day by their parents.
  • See the photo gallery below for more ecological happenings from the past two days.

July 13 and 14 – Weekly Census

Posted on by

Ecological Notes:

  • The sea lion population is growing. For the past few days there have been 18 Steller sea lions hauled out on Middle Rocks. That is up from four sea lions one week ago. One of the sea lions has a brand. It appears to say 620R, although the researcher I contacted in Oregon mentioned it is what they call a bad brand and he was unable to determine the brand from the photos I sent. I will keep a look out for the sea lion and see if I can get a better view. The researcher will check his records to see if he can identify the sea lion and be able to record the resighting.
  • The super moon on Wednesday night rose in the southeast at 10:00pm. It was a big bright orange orb that looked more like the rising sun, than the moon.
  • Today’s extremely low tide of -0.2m or -0.7′ was at 10:13am. The overnight high tide at 00:55am was 3.0m or 9.8′. It is apparently the lowest tide in a decade. I was fascinated to see the extended edge of the water all around the many islands. I looked at the exposed intertidal zone from a distance and up on the jetty, so as not to disturb the many delicate species.
  • See the photo gallery below for more ecological happenings from the past two days.
