Every days are a little bit the same; on Monday the 15th ,we had 20 knots at 5:00AM with a visibility over 15 miles and a choppy sea and this stayed the same to late in the afternoon where we got 33 knots and later around 30 to midnight. On Tuesday it was foggy almost all the morning,17knots at 5:00 AM, with a good visibility to 6:30AM; Air temperature 14 degrees Celsius and water around 13. Barometric pressure:101.8KPA
Nothing really new except that we found 2more chicken bodies for a total of 15. No elephant seals around. With those very low tides it is very interesting to discover the treasures of the intertidal zone .
Guy chopped more wood ,pile almost gone. The wheelbarrow is …dead at least the wheel. The electrical fence on the jetty is settled.We will see its efficiency . This year no line on boat side ,it’s too risky for us.
No visitor but Kyle went around with a group of marine biologists.(meeting this week at the college)
Plane above.Watchers in the morning mainly
It was a westerly kind of a day, gusting 25 – 30 knots all morning under partially clear skies. In the afternoon gusts were stronger, churning the sea into a white froth. The wind speed dropped to 20 knots in the evening and was closer to 15 by the time the sun went down. Although the fog was threatening early, it stayed off to the west and the haze that has hanging around was cleared by the wind and replaced with building clouds. The strong wind warning continues and the forecast for Monday is mainly cloudy. The barometer continues its step-wise descent.
In spite of blustery conditions and because of all the marine mammal action there were 18 visits observed by commercial tour operators today. Whale watching was good in the area today and the sea lost some salt to exhilarated looking tourists who had their hoods on and exposure suits battened down in the smaller open boats. No other vessels were observed in reserve.
It was another exciting day on the mammal front with Humpbacks all around, Killer Whales in Race Passage, an increased number of sea lions and return of at least one elephant seal to Great Race Island. Salmon continue to be an important part of gull diet in the area and that is mostly due to scavenging off kills by sea lions.
One of the California sea lions that hauled out with a big new flasher last week, has managed to get rid of it. I am not sure if the hook is inside but today he just had a little broken piece of the flasher hanging out of his mouth when I went to do the seawater sampling and when I came back it was lying on the walkway with its bead chain still looking shiny. There are several ‘necklaced’ sea lions here right now. They all seem to have white plastic strapping around their necks and it looks deadly.
There are only a few Glaucous-winged Gulls left on Great Race and not many more that are still being fed by parents. I photographed one juvenile eat salmon caviar brought back and deposited with special serving and plating effects by its parent. Lots of people think that gull is just a four- letter word associated with human garbage and super abundant. Glaucous-winged Gulls are the only species (of ten species seen here) that actually nest in the Salish Sea and their numbers have been declining for a few years now. Known in birder code as GwGu this four letter word represents an important species in the local ecosystem that is a risk due to human activity. In many areas plastic pollution poses a serious threat to young gulls that do not know better than to eat it. From the evidence so far far at Race Rocks, GwGu have been fairly plastics-free. Lets keep it that way.
Although most of the bull kelp is still very strong and beautiful, many of the stipes have epiphytic green or red algae growing on them now as they start to senesce. Bull kelp is an annual species and it grows very fast during the spring and summer. Soon the storms will be dispersing these incredible carbon sinks and some will end up on the bottom entombed in mud. Sinking plankton takes the most carbon to the bottom, helping make the ocean the world’s biggest carbon sink for atmospheric carbon dioxide. Thank you ocean, for being such a complex regulator of climate.
Ashore, the Calendula is still blooming giving new meaning to the term perennial. This plant flowers all year round here, looking as fresh in September as it does in March. It closes up when it is cold and wilts in frost but survives as a remnant of a long-gone lighthouse keeper’s garden. Native to the Mediterranean, Calendula’s bright, cheery blooms are incredibly resilient and it is one of the few plants the Canada Geese don’t eat. Although it probably shouldn’t be flourishing in an Ecological Reserve here, I am glad it is here and it reminds me that people are part of the ecosystem.
Again chores were routine and there were no visitors.
The wind blew steadily 25 to 30 knots from the west today, all day. The morning was relatively calm on the lee side but by early evening it was really rough all around Race Rocks. Cloudy morning skies gave way to a sun-dominated mix, of sun and clouds in the afternoon. There was no precipitation in spite of the clouds. Remarkably, the total annual rainfall here to date is ~22 cm, not much. The barometer climbed back up to 1016 hPA., before starting another little slide. The forecast is calling for sunshine with increasing cloud and continuing strong westerlies.
No vessels were observed in the Ecological Reserve during the day today. One whale watching vessel was observed working in the Reserve just at sunset.
Ecological happenings are all in motion and continue on the path that has been described over the last few days. The bull kelp growth may be slowing as evidenced by some epiphytic growth showing on a very small percentage of the “plants”. These algae are super carbon fixers and not only crank out food, they also grow so thickly that they shelter the Sea Otter and today I saw a small Harbour Seal actually climbing out of the water onto the bull kelp. It is slippery stuff so I was surprised when I looked a few hours later: it was still there and had managed to dry off the upper part of its body while hauling on bull kelp.
I realized today that the Harbour Seals, of which there are a lot more (225 to 250) than Northern Elephant Seals (maximum count 35), may have had the short end of the stick when it comes to mentions in the Log entries. Maybe it is because the elephant seals are up close and personal and not bothered by our presence. Maybe it is because it has been such an priviledge to get to know the elephant seals and their diverse personalities and behaviours. The Harbour Seals are further away and hard to tell apart as individuals. An adult Bald Eagle was very interested in the Harbour Seals today and although it is early for inside waters, I thought that there might be some pupping activity soon.
Chunk and Floyd often sleep together behind the science house. Floyd’s moult is more than two thirds done while Chunk has not even reached a third yet.
Chunk and Floyd also have their battles and tonight they chose to fight in amongst the nesting gulls, crushing at least one nest and killing an adult that was trying to defend its nest.
My favorite bird here continues to be the Black Oystercatcher, there is something about their very spartan nests and their willingness to take on adult Bald Eagles and Ravens that makes me cheer them on. Their looks are pretty great too. The newly hatched chicks are very precocious and can follow parental commands almost immediately. They are so good at remaining perfectly still when “told to” that they are almost impossible to see. Thank goodness for telephoto lenses. I will try to get a photo of the chicks from a distance tomorrow.
There were no visitors today and chores were routine as I wrap up the last few days of my shift.
Light airs from the southwest and a light overcast sky, dominated the first part of the day. At about 16:00, an abrupt directional switch to west by northwest saw winds rise to 20 to 30 knots within a few minutes. Those winds were accompanied by moderate rain and a darkened, overcast sky. The wind direction remained the same but velocity dropped to 5 – 10 knots after the storm passed through leaving sunshine and outrageous double rainbows in its wake. The barometer continued to fall slowly today and the forecast calls for west winds and a 40% chance of showers.
There were five whale-watching boats observed in the Ecological Reserve today all during the downpour. One sports fisher was observed speeding in the go-slow area.
A sea otter was spotted in the Ecological Reserve again today, after being either absent or well hidden for almost a month. Thanks go out to the operator of the Prince of Whales vessel in the area, for radioing the location and description to me.
On land, there are many flowers blooming on Great Race right now. Many of the flowers are heritage plants, part of the legacy left by light keepers from 155 years ago and on.
An exception to the imported non-native plants, are the Mist Maidens blooming right now. There are several patches but the most vigorous one is in the scree above the Pigeon Guillemot nesting area, just uphill from the boat-house. Mist Maidens or Romanzoffia tracyi are considered to be a rare plant and I will take some photos to share with you tomorrow if the light is better.
A group of visitors were here today using the science house and Great Race for a retreat. Courtney brought them out on Second Nature and stayed to help trouble-shoot a few issues with the generator and aggressive geese. Alex left with Courtney in the afternoon.
This plant was introduced to Race Rocks by Assistant keepers in the 1980s. From a small flower bed near the assistant’s house It has spread over much of the Great Race Rock Island. Since it is a member of the Crassulacea family, it uses the crassulacean acid metabolism (CAM) method for fixation of
Carbon Dioxide for photosynthesis. Since it can fix Carbon into a chemical when stomata are open only when its cool at night, it is very resistant to drought, and can survive with very little soil.
It is of course not the only introduced species on Race Rocks but since it is not grazed by anything, it is rapidly replacing the sparse growth of native species such as thrift and grasses in the rock crevices.

The flag was set at half-mast today to mark the national day of remembrance of the Battle of Vimy Ridge. According to the Canadian War Museum, the capture of Vimy was more than just an important battlefield victory, it became a symbol for the sacrifice of the young Dominion. Brigadier-General A.E. Ross declared after the war, “in those few minutes I witnessed the birth of a nation.”

This morning was the first time this Spring that there have been a few California Sea lions resting on the end of the jetty.
With Spring mostly here, many of the introduced ornamental plants are flowering. This isn’t a complete plant inventory, just a selection of plants that I noticed on my photo walk. The terrestrial plants at Race Rocks are dominated by introduced and invasive species. This is something that occurs at most light stations. There is a long history of trying to make the light stations look “like home”; Which is usually done by introducing hardy ornamental plants that can survive (although only a few thrive) on remote, salt and wind blasted light stations.

On the morning of Wednesday June 6 , I went with Andy MacDonald, the Vancouver Island Region (South) Parks and Protected Areas Section Head, and Zsana Tulcsik, the new BC Parks Area Supervisor from the Goldstream Office out to the Race Rocks Ecological Reserve. ( A report by Garry Fletcher, Race Rocks ER warden)
College staff member Erik Schauff skippered Second Nature and we met Chris Blondeau , Director of Operations for Pearson College UWC on the jetty. He is the relief ecoguardian at Race Rocks for the week .
The elephant seals co-operated and were basking in the sun on the grass in the centre of the island. There were 4- 2 year olds and one large older Male, which may have been Chunk … the inflamed right eye from an injury administered by Misery was a good identification mark.
Two Northern sea lions were observed in the water . I thought it was notable that there were very few harbour seals which usually have pups at this time of year, and none on the southern islets where they usually haul out. I will have to check over the next few days on the tower camera, as they may have been out foraging.
The glaucous-winged gulls are well into nesting season, with several nests containing three eggs. The image from the window of the science centre shows the distribution of pairs. Another picture above shows a nest precariously close to the elephant seal haulout spot.
There was an abundance of pigeon guillemots on all corners of the island where they have their nesting burrows. They should be visible on camera 5 now out near the edge of the cliff to the west. They have certainly been a success story in increasing numbers in the past few years. There must be well over 60 pairs nesting in the hidden burrows under the rocks. Ironically good habitat has been produced in several areas because of human activity in the past by the blasting of rock for the helipad construction by the Coastguard, and other construction on the islands done in the 1900s before it was an ecological reserve. This is a rare example of habitat enhancement that humans can claim, as usually it is the other way around.
On the return to the docks we were impressed with the clumps of Thrift in full bloom. Chris mentioned that the Black Oystercatchers had been in the area on the rock right off the sidewalk by the docks and we soon spotted the nest. This is the same area they have used for many years. The videos of the hatching oystercatchers in this link are from the same area.
In addition to the vast monocultures of pineapple weed as shown above, this is the second year we have noted large patches of Fiddleneck, Amsinckia spectabilis in the same compacted and richly fertilized areas where the grass was killed out by the sealions and intense Canada Goose grazing.
