Getting Busy round here

Posted on by

More and more tour boats are visiting the reserve this week. It is easy to loose track of the numbers because they come out of nowhere it seems and from every direction. I estimate we are seeing about 20 visits a day this week. This may be because the orca are out of range, and Race Rocks can always be counted on to provide a picturesque opportunity to see marine mammals in the wild. By and large the tour boat operators are respectful but some operators seem ignorant of the reserve boundaries and come in or leave a little too rapidly. I will be emailing the companies to clarify this issue when I have some photographic evidence.

This enormous vessel is new. I will be curious to see how marine mammals react to it. I suspect it will have less impact than the zodiacs because it will stay a bit further away and more people will see the animals on one trip than 6 or 8 zodiac trips. We will see!

This large California Sea Lion arrived yesterday. He has a brand that appears to be 909 (or 606). More pictures of him coming soon….

There are 6-7 elephant seals finishing up their moulting now. On occasion we get a little traffic jam on the ramp. Here Bertha reminds the others who is boss…

The military conducted several over-flights while conducting maneuverers, but at a reasonable altitude.

Yesterday Erik and I shipped 500 gallons of water over, as finding parts for the desalination unit is challenging. I hope that volume will last a month or so…

Busy Little Island – here come the humans…

This weekend the island and reserve is teeming with humans. Seven Pearson students are experiencing a weekend here, we have 4 groups of Pearson students (60 in total) coming out for a biology exam. As well the “Friends of Ecological Reserves” group is coming for a tour in a few hours. But perhaps most obvious are the 25-30 sport halibut fish boats ringing the reserve to the East, South and West. Apparently there is a derby with about 450 fishing tickets sold. Either those boats are crowded or we can expect more before the day is over. Personally I am routing for the halibut!

We had 6 elephant seals here yesterday including numbers 6360, 5086 and 6375. Bertha is back for her moulting time of the year. She seems to go through the process much quicker than the juveniles. You can see the scar that makes her so easy to identify and is testament to her recuperative powers.

One of the juvenile elephant seals managed to wiggle under the chicken wire of one of the enclosures Alex made to measure the impact of Canada Geese on the grass. Turns out a 100 kg e-seal can have an impact on grass too.

She has been liberated but seemed more annoyed than thankful!

Bald Eagle flyover…. a float plane just buzzed us and last night the military helicopter was doing exercises in the area. Chris cleaned the underwater webcam yesterday. You can watch the fish and if you are lucky spot a Sea Lion! http://racerocks.ca/racerock/uwcam/video2frame.htm

Random Encounters

A number of infrequent avian visitors have been popping by for a visit, or more likely a rest on their northward migrations. Two days ago a Greater White-fronted goose (Anser albifrons) spent the night, and the next night a Black Brandt (Branta bernicla nigricans) had replaced it. The brandt stayed two days and fed vigorously the whole time. I just discovered how rare these birds are with only 115,000 in the world.

I have noticed several pairs of Wandering Tattlers (Tringa incana) in the least few days

And another favourite the Whimbrel (Numenius phaeopus)

Finally, the California Sea Lions (Zalophus californianus) have begun to arrive.

The weather has settled after a couple of blustery days and the sun is shining. Erik and I are refuelling the station which involves transporting about 6,000 litters of diesel fuel from Pedder Bay Marina to the island. We should be completed this afternoon. Hopefully this will last about one year, but that depends on conserving energy/electricity wherever possible.

Seven Pearson students spent last weekend here and we may get another group this coming weekend, however that depends on getting a new part for our desalinator. Without water it is challenging to host our guests, and I may have to ration our dwindling supply for a few weeks until the new part arrives. I counted just under 20 whale-watching vessels in the preserve last week, averaging 2 a day with 4 or 5 on the weekends. I will monitor the numbers more closely as tourist season arrives. DND continues to explode ordinance on Bentinck Island, much to the annoyance of every living thing in the reserve. The percussive shock waves rattle the windows and seem very incongruous with the spirit and intention of this place. I can’t quite understand why they won’t perform their exercises in an inland location where the noise and pollution can be better contained. I believe they are violating federal guidelines and hope they will take measures to ameliorate the effects of their mandate.

Hundreds of pigeon guillemots are banding the seashore around Great Race and they add a colourful and busy presence to the island. Three scruffy young female elephant seals are busy moulting their pelage. Little scraps of old skin and fur are littering the island, adding to the biological detritus that makes up the bulk of the soil layer along with guano, shell and decayed plant material. A few California Sea Lions are in the area along with the Stellar and Northerns.

 We have a new camera now with a good telephoto lens so I hope to edu-tain you with beautiful pictures of magnificent animals…. stay tuned!
