Bigg’s Killer Whales Kill in Reserve.

Posted on by

The barometer rose all day and so did the westerly winds, so by the time the tide started to ebb, the opposing forces made spectacular waves. Tonight is the last full moon of the summer and it is in perigee, closest to the Earth, so it appears to be a big one, marking the third of a trilogy of super-moons we have been enjoying. It also means bigger than usual tides, making things seem even more dramatic. It was clear all day, no fog, but there are low clouds sneaking in along the Olympic Mountains and the look of fog out to sea. The westerly is supposed to be a little tamer on Tuesday.

Twenty-one tour boats were noted in the reserve today as well as one dive charter boat. A couple of the whale watchers looked like they were pushing the speed limit in the reserve and pushing the marine mammal viewing regulations outside the reserve. No illegal fishing was observed.

I am adding photos to the sea lion branding/tagging observations and that will make the data much more rigorous. Another entangled, aka ring-necked California Sea Lion was photographed. This time it looked like plastic strapping cutting a deep and infected wound.

Bigg’s Killer Whales visited again today. It appeared that they chased Steller Sea Lions all the way here from at least Albert Head. It was very dramatic here as they wove in and out of the kelp and through the tidal rips and standing waves, going with the tide and at great speed. One exhausted male Steller’s hauled out just as the chase was passing and he looked as though he may have been part of it all. He collapsed in a heap and immediately went to sleep. He was the lucky one. The kill happened in the reserve, just southwest of Great Race. There appeared to be a fairly small baby in the family of whales. The group was purportedly the T-61s (not sure of the source however). I tried to take photos so will report back with verified identification information once that comes in.

I finished some more of the set up to protect the ‘Science House’ today and started to clean out the northwest entrance to the generator room. There is a lot of very satisfying cleaning here, when you sweep you really get results, today it was many, many, generations of Ligia pallasii exoskeletons. Wow it’s a moult room instead of a cloak room.

What’s your number?

It was a day without fog at Race Rocks and as the westerlies continue, some serious clouds can be seen piling up on far horizons. The barometer rose all day, which bodes well for tomorrow but there may be a few needed showers.

It was a busy day on the water with 26 whale watching boats visiting the reserve. From the expressions on the tourists’ faces, they seemed to enjoy watching the sea lions. All the skippers were respectful except for two travelling together who did not heed the go-slow zone.

There were so many recreational fishing boats that I could only keep track of the ones who were in contravention of the DFO Rockfish Conservation Area closure which runs around the reserve at a 40m depth. Many of those fishing inside the boundary were in rental boats but some of the other speed boats were doing what they do best…speeding. The Pedder Bay Marina is really good about talking to folks who rent from them and informing them about the conservation area.

I looked for tagged and branded sea lions again today and can report another nine California Sea Lions and four Stellers’ Sea Lions bringing the total number of branded individuals sighted up to 29. Eventually we will know a bit more about their stories from those numbers they carry. There are also two Stellers with neck rings cutting into their flesh and one with a flasher hanging out of its’ mouth. There are individual Harbour Seals, as well as both species of sea lions with major wounds. Speaking of wounds, there were two new, (to me), very small Elephant Seals on the ramp today, probably young of the year, judging from the size.

A few Pigeon Guillemots are still carrying into fish into the large boulder area by the jetty. The chicks must leave for sea at night as I haven’t seen any on the water and most are probably fledged by now. Each day, there are more Pelagic and Double Crested Cormorants roosting on the southwest side of the island.

The desalinator worked for a couple of hours during the sunshine today, making fresh water thanks to the solar panels.

Month end inventory was conducted today with measurements taken of all the fuel, fresh water, and equipment run times recorded.

My other task was to try and stake out a small territory on the jetty so that I can come and go and do the sampling. The elephant seals are no problem, they just sleep as you pass, or open one eye. Keeping the more belligerent California sea lions off the jetty seems to be a losing battle and has made getting out to the end of the jetty to sample seawater, extra challenging.

Injured Steller Sea lion

Clear skies. Strong West winds. Force 6-7.
Barometer was rising most of the day, started to drop around 1200. West gale warning continues for tomorrow as a low pressure moves towards the mainland.

9 tour boats
2 recreational boats passed through the reserve

Yesterday, around midday, an injured Steller Sea lion arrived at Great Race. I saw it swimming through the current below the West cliffs while I was looking for transect pegs. It sussed out the boat ramp (which was full of Elephant seals) and then settled just East of the boat ramp, not far from the crane. It was in the same spot this morning, and stayed there all day. It has a salmon flasher caught in its mouth, and large wounds on both sides. Garry Fletcher suggested it might be an injury from a shark or orca bite. A lot of tour boats have gone through the reserve these past two days, right past this Sea lion, so I expect that it has been thoroughly documented in many people’s vacation photographs.
