Census on a Cloudy Day

Census Day!

This morning, Scott and I headed up to the top of the tower for our weekly animal count.

We added the elephant seal to this week’s survey because she is still sticking around!

Yesterday we beefed up the fence on the West side of the island between the helipad and the generator shed. Since this one isn’t anchored into the bedrock, it has been taking quite a beating from the westerly winds.

Greg also dropped by yesterday and gave us some groceries for the week. The water cistern is quite low, so we have ceased using the desalinator, and are trying to be more conservative than normal with the water. Fingers crossed, Greg will be able to boat over some more water this week!

Today, we checked and topped up the batteries, and tidied up the basement in the main house. I can’t believe we only have a week left on the island!

Sunday September 8th

Today we spent a lot of time on the fence again. We painstakingly went through each section to ensure that charge was being held the whole way through. This was a very tedious process and we still don’t have the voltage up to where we want it to be…. but there have been no pinniped breaches yet, so fingers crossed!

Today, Scott and I climbed the lighthouse tower to complete our first wildlife census. As a marine ecologist, I have a lot of experience counting fish underwater. However, counting over 600 Sea lions that all look like overlapping brown logs or trying to count birds that keep on flying away or are hidden between all the sea lions was way harder. With that said, being a top the tower made everything much easier to see and to conceptualize on a greater scale.

While we were up there we also got to enjoy a couple of humpback whales engaging in tail slapping or “lobtailing” behaviour for well over 30 minutes. It is thought that the sound and force generated by the slaps frighten the bait fish into tighter schools making them easier to hunt. Based off gull activity, there were definitely a lot of bait balls around, so hopefully we will get to see more of this behaviour in the coming days!

Wildlife notes:

The entangled Stellar sea lion was not spotted today on Great Race Rocks. A Stellar sea lion with a dark coloured stain around its neck (possibly a packing band), reported previously by naturalists on the ecotourism boats, was sighted on Middle Rock during the census.

The Stellar sea lion on Middle Rocks with a possible new entanglement is located in the bottom centre of the photo and has a dark coloured ring around its neck.

I wish I could sleep like a sea lion, on any surface, cold, hard, flat or bumpy and with only a log for a pillow.

Mammals

sea otter: 1
elephant seal: 2 (male and female)
harbour seal: 192 (48 South Islands, 54 South Seal Rocks, 36 Middle, 16 Turbine, 33 North Is., 5 Great Race Rock)
sealion: 5 (on West Rock, too far to identify)

western sandpiper: 1
least sandpiper: 1
harlequin duck: 2

Wildlife notes:

The last of the gull chicks are hatching. Only about 5% or less of the gulls are still sitting on eggs. Gulls get a bad rap and called names like shit hawks. It is true there are white streaks and splotches everywhere, but if you watch the nesting gulls, parents and even the larger chicks, they take great care to walk up to 6 feet away from their nesting area to do their business.

Some photos the elephant seals sleeping side by side.

Facility work:

  • cleaned solar panels
  • thistle removal complete

Vessels:

3 ecotourism, 1 private

Weather:

Cloudy early morning. Fresh westerly breeze in the morning, steady strong breeze the rest of the day. Daytime temperatures: minimum 13, maximum 14 degrees.

Wildlife notes:

The California sea lion with the wounds on his flipper hasn’t been spotted for a few days.  The new black oyster catcher chick hatched on July 5 in the open on the western shore has been moved up higher on the rocks.  The pigeon guillemots are easy company – neither the gulls or the oyster catchers mind them around.

Another little climber. Hatched July 5.
