August 24

Much quieter day workwise today.

The sea lions are taking over! They have knocked the fencing down in several places and once again have cleared the fence posts from the jetty. I am conceding defeat! I know Greg and Richard are planning to redo the fence system this week, so the sea lions can claim victory–for now.

During yesterday’s census, I saw a Glaucous-winged Gull with a seriously broken wing. It looked like an old injury given the condition of the wing. I couldn’t relocate it after viewing it from the tower, but today it was near the solar panels. I managed to catch it and will take it to WildARC when I leave on Monday.

The bird of the day remains unidentified. I flushed a small sparrow twice today, but it went too far for me to get a positive identification. I suspect it is a Savannah Sparrow. I am annoyed I didn’t get a better look as there are very few songbirds here.

The entangled sea lion is still present. Fingers crossed for a rescue soon.

  • Clean the solar panels
  • Clean the west and north windows of the Science Building
  • Took hydrometer readings of the batteries in the generator building.

Weather:

  • Sky: clear and sunny all day
  • Wind: variable 0 – 20 knots
  • Sea: rippled
  • Air temperature: low 13 °C, high 27 °C

Western Gull, an uncommon species for Race Rocks, although there are a few who are breeding with Glaucous-winged Gulls on site.

August 23 Weekly Census

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!
