Census July 6

Ecological Notes:

  • I am seeing more gull chicks everyday. Many gull parents are frequently feeding their two or three chicks.
  • I seem to have come to an understanding with some gulls. If I approach near them on the path at a slow speed, we both ignore each other. There are other gulls who freak out if I even look in their direction. As I do necessary work, I limit my movements around the island and avoid certain paths that have nearby nests and chicks.
  • See photo gallery and captions for more details on the ecological happenings over the past two days.

August 16 – Returning Sea Lions

Wind: from NE in morning, SE in afternoon, W in evening – between 2 to16 knots
Sea State: calm in morning and rippled in afternoon
Visibility: 15 NM
Sky: clear
Temperature: 16-25 °C
Atmospheric CO2: 412.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

While I have only provided the conditions for today, I did step onto the Rock just after noon yesterday. It’s great to be back, having spent the whole winter and the first few weeks of spring here. I will be here for the next two and a half weeks, 100 days shorter than my last stint.

I feel very fortunate to be a part of the amazing team of Pearson students, alumni, staff, volunteers, donors and researchers who keep this Ecological Reserve going.

I spent yesterday afternoon and evening reacquainting myself with this wonderful place, practicing how to avoid disturbing the young gulls, who blend in well with the rocks as they like to hide beside the paths and in plants.

This weekend, there have been a lot of boats (pleasure craft and eco tour boats) taking advantage of the nice weather. The only visitor to the island, other than me, was Greg, who drove me out here from Pearson and brought back Mara and Kai.

In the previous log post, on August 13, a branded sea lion with an attached flasher (fishing lure) was mentioned. The steller sea lion is branded O-19. Bryan Wright, the Marine Mammal Biometrician/Project Leader at the Oregon Department of Fish and Wildlife, gave us an update on the history of the stellar sea lion:

He was captured and branded by us (ODFW, along with WDFW) at Bonneville Dam on the Columbia River on February 2, 2012.  We don’t know his exact age but he was probably 5-7 years old at the time of capture, making him 12-15 now.  He then wasn’t seen again until July 21, 2016, at Tatoosh Island off the tip of the Olympic Peninsula in Washington.  He was then next seen back at Bonneville Dam from August-November, 2019.

Bryan also passed along an interesting article that was just published called “California Sea Lion (Zalophus Californianus) Monitoring In The Lower Columbia River, 1997–2018” (Brown et al 2020). Click here to read the abstract of the article.

April 5 and 6 – Orcas

Wind: yesterday variable 0-17 knots, today variable 0-22 knots
Sea State: both days rippled
Visibility: both days 15 NM
Sky: yesterday partly cloudy, today clear
Temperature: both days 5-10 °C
Atmospheric CO2: 416.03 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Yesterday morning, I noticed a pod of at least six orcas on the western edge of the ecological reserve. They swam east through Middle Channel, passing just north of the main island. What a treat it was for me to watch them from the front porch. See the photos below.

The older of the two female pups has been gone for the whole day. She left the island at some point early this morning. It’s been 14 days since the oldest of the three surviving pups left the island. Perhaps the pup who left today is following the strict schedule, as she is 14 day younger than the male pup who left 14 days ago.

Today, there were three boats in the ecological reserve: two pleasure craft and one local whale watching boat with two people on board.

 

Strong Westerlies

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.

March 20 – Spring Equinox

Overcast with occasional light rain
Wind: NE 6-15 knots
Air Temperature: Low 9.2°C, High 11.2°C
Ocean Temperature: 8.8°C

The Spring Equinox brought more of the same weather. The daffodils, which have been in bloom for about a month, are beginning to die off. The canadian geese and gulls are still spending their days looking for their future nesting sites. They are getting more aggressive with each other. I don’t need an alarm clock in the morning, because the birds wake me up with the sun. The goose droppings are piling up in various deposits around the main island.

Courtney brought out a group on Second Nature from Pearson: Roman, Noemi, Roger, Catherine, Heather and Kim. They will be staying for the weekend and helping with some service projects on Saturday.

Sun and Calm Seas

The wind blew from the north between 13-15 knots, until 10:00 this morning.  Then the wind shifted towards to northeast and calmed down to between 2-9 knots.  The sea was very calm, with no swells or whitecaps.  The barometer rose from 1020 hPa to 1024 hPa. The temperature increased slowly throughout the day from 1-4oC.

There were no boats seen in the reserve today.

If solar panels could be happy, they would have been happy today.  The sun shone brightly, juicing up the photovoltaic cells.  It wasn’t enough to melt all of the snow and ice, which remains in patches around the islands.  Some of the plants have begun to wilt from the prolonged cold weather.

I made a trip into Pedder Bay this afternoon.  Having been solo for the past two weeks at Race Rocks, it was great to catch up with some students and staff at Pearson.  I also dropped off garbage and picked up gas.  The northern half of Pedder Bay was frozen over with ice that was 2-3cm thick.  It made boat travel tricky.  Luckily there was a lane of broken ice just wide enough for the Boston Whaler to travel from the Pearson dock to the Pedder Bay Marina, where the gas was filled.  Unlike driving a car on ice, a boat stops when you hit ice, so it’s much easier to handle.  On the return trip to Race Rocks, I saw a large group of surf scoters between the mouth of the Pedder Bay and Race Rocks.

Calendula officinalis: marigold–The Race Rocks Taxonomy

Many of the pathways are lined by this plant.

Although introduced to Race Rocks by  lightkeepers to brighten up their garden years ago, Calendula sp.is an interesting exotic since because of the ocean moderated temperature of the Ecological Reserve, it blooms at Race Rocks every month of the year. The reason it is so successful there is probably that it is not grazed by gulls or geese.
