August 23 Weekly Census

Posted on by

First things first! Time to check out the solar panels, while at the same time, keeping track of what animals and birds are being seen. Census is usually conducted on Friday, but since I didn’t arrive until mid-afternoon, I opted to do it today.

The solar panels were in better shape than I expected given the look of the Science Building windows. I remembered all of the valves that needed to be opened to provide water on the generator building roof, so a single trip up the ladder was all that was needed. Once those were taken care of, it was off to tackle the Science Building. There are some great new tools available for reaching the second story windows, but they are quite unwieldy, especially for someone who is just a little over 5 feet tall! As I feared, the gull artwork was baked on, so although there was improvement, the windows were not fully clean when I was done.

Next, a trip up the tower to count marine mammals and gulls. I found a key outside the door as I entered. The fob looked somewhat familiar, but I couldn’t quite place it. I thought one of the guests might have dropped it yesterday, so left it at the bottom of the stairs. A hundred steps up, I remembered why it looked familiar–it was the key to the hatch to the outside of the light. Down 100 steps and back up 100 steps. A double workout for today!

While at the top, I called my friends at Rocky Point Bird Observatory just the other side of Bentinck Island and arranged a neighbourly wave. There is a gap in Bentinck that provides a great view of Race Rocks from the other side.

Census complete, I headed back to ground level. Hmmm..Where are my glasses? You got it–back up at the light! Another trip to the top!  Although I had done a count of gulls from the top, I decided to count the young birds again. They are difficult to see from the light. At ground level, I found about three times as many as I had counted from the birds’ eye view.

The sea lions had dumped most of the posts and their concrete blocks off the jetty again. I managed to get them back up before the tide rolled in and repaired the fence–again. I have to say, I felt that I’d put in a full-day’s labour before noon!

Wildlife Notes:

  • A couple of humpback whales passed through the northern and eastern side of the ecological reserve this afternoon. At 14:30, I saw a spout just beyond the North Rocks and watched as the whales swam south. I heard over the radio from the ecotour boats that there appeared to be a mother and calf. I was surprised to see several sea lions swimming around the humpbacks. Most likely the sea lions were feeding on the fish that were being stirred up by the big whales.
  • Early this afternoon, I noticed a Steller sea lion that had hauled out on the boat ramp beside the jetty. The sea lion did not move when I walked near it several times to fix the electric fence at the end of the jetty. It also wasn’t breathing, so I suspected it had died at some point overnight or this morning. I checked on it at this evening’s high tide at 19:30, by which point the sea lion’s mouth and nose were just under the water, but there didn’t appear to be enough tide to take it out. I reported it to the DFO (Department of Fisheries and Oceans) BC Marine Mammal Response Network, in case they want to check it out. Fortunately, I did not notice any signs of trauma on the animal from what I could see on the top. It had some battle scars on its back like most of the male sea lions and elephant seals I see. I am fairly sure it’s a male that is not mature, based on the thicker neck but not bulk of the fully mature males.

Facility work:

  • Fix parts of the electric fence that were breached by party animal California sea lions. One made a foul mess at the end of the jetty that I washed away with many buckets of sea water. Any excuse to use a bucket on a rope to pull up seawater.

Vessels:

  •  Ecotourism: 13
  •  Private: 2

Weather:

  • Sky: partly cloudy
  • Wind: variable directions 0-30 knots
  • Sea: riippled

Wildlife Notes:

  • I don’t need an alarm clock here because my neighbours get excited when the sun rises. Eagles do a few passes of the island and freak out the gulls. The growing concentration by the jetty of sea lions bark and bellow ever so slightly louder in the daylight.
  • This afternoon, I got word from an ecotour boat that a northern fur seal was spotted several nautical miles west of the ecological reserve. Hopefully the seal stops by here like one did in December and April. Before that, a fur seal had not been spotted at Race Rocks in over four decades!

Facility work:

  • Clean the 44 solar panels first thing this morning before the guano got baked on by the sun
  • Clean the windows of the main house
  • Laundry load of sheets and towels used before I got here in July. There was plenty of solar power to accommodate the extra power load of the washer and dryer. While the dryer is heated with propane, the motor still draws a few hundred watts of power.
  • Remade some of the depth sounding charts around the island that are getting hard to read. We used these charts to see how many litres of diesel are in the tanks by dipping a ruler into the tank to measure the level.

Vessels:

  •  Ecotourism: 22
  •  Private: 3

Weather:

  • Sky: Partly cloudy
  • Wind: variable directions 3-25 knots
  • Sea: rippled in morning, up to 2′ chop in the afternoon

Wildlife Notes:

  • A brown pelican flew by the ecological reserve this afternoon, stopping off briefly in the water on the east side, just past the large kelp bed. The pelican did not stay long before flying back through the south channel, which allowed me to snap photos (see below) of the big bird in flight.
  • After five days off looking from afar, I finally was able to see some of this year’s black oystercatcher chicks. Christine’s map of oystercatcher nests from June 1 has helped me find where the oystercatcher pairs are located, but the chicks are either too well camouflaged or are no longer around.
    This afternoon, two chicks and their parents were between the ecoguardian’s house and the edge of the east beach. The chicks are looking more like adults with their orange bills, pink legs, and black feathers. Like other chicks born on Race Rocks, they begin their lives blending into the rocks as grey fluff balls.
  • This afternoon, there was a flock of ecotour boats gathering to the northwest of the ecological reserve. A pod of orcas in Race Passage (directly to the north) were travelling near the shore of Bentinck Island.

Facility work:

  • Top up the water in the batteries
  • General tidying
  • Take measurements for an instrument installation

There were many humpbacks to the south of the ecological reserve again today. They were too far away to get any decent photos even with the 400mm lens.

The population of the California sea lions is increasing by a few each day. I woke up this morning to their barks in the east bay.

Facility work:

  • Clean the 44 solar panels
  • Check the electrical systems on the station boat
  • General tidying around the island’s buildings

Wildlife Notes:

There were many humpback whales seen throughout the day to the south of the ecological reserve. They did not come close enough to this rock for any great photos. Although that did not stop me from trying. Many ecotourism boats spent time out there observing and must have got excellent photos from their vantage.

Three California sea lions have landed on the main island. This advanced team marks the beginning of the takeover that will last into the fall and winter, when several hundred of them will sleep, bark, and attempt to occupy any surface. The Californians have not always been the best neighbours at Race Rocks when it comes to the human built infrastructure. So far these three have been respectful and keeping to the perimeter.

A few times today, I saw a very small and fast bird flying around the middle of the tower. I wonder if it is living in the currently malfunctioning foghorn sensor nearby where I caught glimpses of the quick bird. Coast Guard technicians are planning to visit next week to do maintenance on their equipment like the foghorn. I will keep looking out with binoculars for the fast flyer. Hopefully the bird is actually living in the recently installed nesting boxes attached to a post above the ecoguardian’s back porch.

Facility work:

  • Run generator in the evening to top up the batteries after not getting enough solar energy on the mostly cloudy day
  • Clean windows in the lantern room so I can better spy on marine mammals
  • Clean ecoguardian’s house windows so I do not have to look out through guano

I will contact NOAA and DFO to report the resighting of the California sea lion with the tag 13-2. The orange tags mean the sea lion was rehabilitated. The tag on the left flipper means the sea lion is a male. I will update the log when I hear back about his history. The rest of the California and Steller sea lions are currently hauled out on Middle Rocks. Perhaps this guy needs a break from the frat party.
