Christmas Bird Count at Race Rocks 2020

Today was the annual Christmas bird count. Martin Stewart provided the transportation on the boat Ecosphere for Matt and Courtney Cameron to go out to Race Rocks Ecological reserve from Pedder Bay with Garry Fletcher. 

Observations were done from the marine a out through Pedder bay and then we docked at Race Rocks to be met by Courtney the Ecoguardian.  We had only a brief window of time, probably an hour  there before the wind started to pick up from the North East, but that was adequate to get a good count of the birds on shore.

Pam Birley from England took these photos on camera 5 :

Striking in their abundance were the and Pelagic and Brandts Cormorants. On leaving we circled around the South side of the islands and out past West Rock where there were also large numbers of cormorants.  From West Race Rocks we went over to Emdyck Pass behind Bentinck Island and found another large gathering of Cormorants, and some alcids.  The other bird that seemed much more frequent than previous years were the Black Turnstones

On the island, after stepping carefully past a male elephant seal on the jetty, we were able to view the new pup and mother elephant seal with the large male up on the lawn by the house. 

The following three sets of data are from their e-bird posts,

The Problem with Ocean Fouling/succession-

When installing equipment underwater in a high current zone where the water is laden with nutrients from upwelling as it is at Race Rocks, it becomes obvious very soon that any new substrate placed underwater becomes an instant habitat for the settlement of many invertebrate and algal species. For this page I have brought together different examples from the work we did over the years at Race Rocks.  . It should be noted that the word “fouling”is a rather perjorative term, seen from the point of view of a natural process interfering with human wishes.  However,  it simply represents ecological succession, a perfectly natural event in a highly productive environment, and too bad that it inconvieniences us!

This video from 2001 shows what the condition of the growth of life was on a sensor bar that we installed in water at 8 meters depth just off the Jetty at Race Rocks: The sensors were for monitoring Oxygen, salinity, ph, and turbidity. Without constant attention by our divers getting accurate data from sensors like these over a long term would not be possible. This video was taken after three months in the water .

 

 

 

In September of 2011 we ended the experimental Tidal energy Project at Race Rocks.  This file has images of the turbine covered in fouling organisms when it was raised for the final time: 

 

 

 

Examination of the tidal energy installation after being installed for 6 months

 

 

 

The engineers concern for the kind of materials they were going to use in constructing the turbine were addressed by having the Pearson College Divers install a series of succession plates that could be monitored for growth over several months.

 

Video inspection done by Chris Blondeau on turbine inspection before removal, June, 2011 The growth of Invertebrtates is quite incredible. Since ther is little opportunity for predators like starfish to browse on this column, growth is unimpeded. This led us to decid that the i meter wide .. 15 metre high column should remain in place after the turbine was removed as such it has turned out to be such a unique  habitat.

 

Another example of succession is evident in the way that kelp attaches to a solid substrate and can end up in modifying the environment. In this case moving rocks from ocean to shore.

 

Measurement Exercise

Today we had a request from Meghan Byrne, a 6th grade science teacher in the San Francisco Unified School District. She was doing a lesson with her students on size and scale and she was interested in using the following picture from this blog of the elephant seal measuring device – and letting students determine its length.

 

 

 

So I thought that would be a good exercise to include here for school students. Ecoguardian Mara has provided the following photos of the boat ramp rail so you can now calculate the length of the small elephant seal. 

Be sure to calculate the length of the Elephant seal in both centimeters and in inches.  Then you can also convert it to Metres and Feet . 

Mara sent another picture of a larger male, the brackets on the rail can just be made out so calculate his size.

The Origins of an Ecological Reserve-Trev Anderson turns 100

Trevor Anderson at age 100

On October 22nd  we were invited to the 100th year  birthday party for Trevor Anderson, the light keeper at Race Rocks when it became an Ecological Reserve. Trev and Flo Anderson had arrived at Race Rocks with their family in 1966, and served at the station until they had built a boat and left to sail across the Pacific Ocean in 1982. They had been married for 70 years in 2014  and  Flo Anderson passed away in 1977.

  I first met the Andersons in 1976 and the students from Lester Pearson College in the Diving Marine Science and Biology programs started coming out to the Islands for field trips and SCUBA diving, with some even spending their project weeks studying and working at the islands. Students in the Diving and Sea Rescue Services at Pearson College developed a close relationship with these neighbours 5 km out at sea. After many of our dive sessions whenour students were invited into their home for tea and cookies, the students would talk excitedly about the incredible sea-life they were seeing at under water. In the late 1970s we started to visit Race Rocks more frequently and the Andersons invited students to stay on project weeks. 

Trev and Flo were the first to plant the seed of an idea urging us to see if we could get the government to do some formal recognition and protection of the Race Rocks Area.  What they could see at low tide alone was impressive enough, but if the underwater life also could be protected, that would be ideal.  In the years 1997 and 1998 we recorded the unique life underwater by logging dives from over 80 locations throughout the Race Rocks archipelago, and by February of 1979 a highly successful workshop took place, with officials invited from the Provincial Museum, the University of Victoria, and the Ministry of Parks who were all enthusiastic and supportive of our proposal.

Throughout that year we worked at the task of formalizing our proposal, presenting it to cabinet and lobbying to get action. Two students in diving and marine science, Johan Ashuvud from Sweden and Jens Jensen from Denmark were especially relentless in their pursuit of our goal. The proposal had to clear 11 agencies in the government bureaucracy and the cabinet before the Reserve could be proclaimed. These two students invited the Director of the Ecological reserves Branch Bristol Foster, and the Deputy Minister of Parks Tom Lee out to dive and then kept following it up with phone calls, even after hours! Their persistence finally paid off when after a year, the shortest time any reserve proposal has ever taken, the Minister of Parks was able to request Prince Charles on his visit to the college as international board president (April 1980) to make the formal announcement proclaiming Race Rocks the 97th Provincial Ecological Reserve.

The day we received the information that the reserve was proclaimed by the Ecological Reserves Branch of the Ministry of Lands Parks and Housing, The group of students who had worked so hard on the proposal went out to Race Rocks to give the news to Trev and Flo and present them with a very unofficial looking sign. 

 

The next week Trev and Flo asked the group of students who had worked so hard to establish the Ecological Reserve to come out to the island one afternoon where they presented the students with medals and “The Order of Race Rocks” as recognition and appreciation for their work in creating the Ecological reserve.

Sea Lion Rescued Near Victoria (Times Colonist , Sept 9, 2020)

A sea lion with a plastic packing band cinched around its neck was rescued near Race Rocks on Sunday, thanks to the combined efforts of rescue teams from Victoria and Vancouver.

The struggling sea lion was first spotted by Mara Radawetz, who lives in the decommissioned lightkeepers’ residence at Race Rocks, just off the southern tip of Vancouver Island. Radawetz, who monitors the Race Rocks Ecological Reserve with partner Kai Westby on behalf ­Metchosin’s Pearson College, saw the sea lion several times during the week in nearby Juan de Fuca Strait, and said the marine ­mammal was clearly in distress.

“He was scratching constantly at his wounds, which were cutting into his skin,” ­Radawetz said.

She contacted Fisheries and Oceans Canada and the Vancouver Aquarium’s Marine Mammal Rescue Centre, Canada’s only dedicated marine mammal rescue facility and one of the largest rescue facilities in the world, to help free the sea lion from the plastic packing band wrapped around its neck.

Two large Zodiac boats ­carrying the rescue team and several veterinarians arrived Sunday morning, and quickly found the sea lion, Westby said. After being given a tranquilizer ­injection by veterinarian Martin Haulena from the Marine Mammal Rescue Centre, the sea lion was brought onto the shores of Race Rocks and treated.

The plastic band was removed and tracking tags were attached to the animal’s front flippers. A blood sample was also taken, to assist with future studies. After being given a drug to reverse the effects of the tranquilizer, the sea lion was back swimming within minutes, Westby said. “It was great to see them help out an animal that was in such great pain.”

Suffering caused by man-made material such as plastic is an increasingly common problem among sea lions, Westby said. As permanent residents on Race Rocks, he and Radawetz see their share of injuries to sea lions.

“It can be pretty sad to see. They live for 20 years or 30 years, and as the animal grows, the band cuts through its skin. It becomes a really painful-looking wound.”

Diving with Sea lions –and foolish diver behaviour

I am posting these videos from Youtube here with a precautionary warning; The behaviours demonstrated by some the divers could be very dangerous. Trying to touch sealions and putting a hand in their mouth and even staying in the water when they get agitated is very unwise. When a sealion starts snapping his teeth at an intruder it is best to move on.  A sealion bite can be very toxic, and they have been known to ram into divers , especially if a diver enters a zone where they have been actively  hunting for fish.  Department of Fisheries regulations warn against any interaction with marine mammals

 COASTAL CHARACTERS BY MARIANNE SCOTT

TREVOR ANDERSON

Air Force veteran, lighthouse keeper, offshore sailor

Only a few Second World War veterans remain with us today—Trevor Anderson is one of them. At age 99, he vividly recalls his war experiences, serving as a Morse code radio operator and doubling as gunner. “When the war broke out in 1939, I tried to enlist and finally made it in 1941,” he told me. He received his radio operator and gunner training in Calgary and Saskatchewan and eventually made it to England. “I was required to signal 16 words a minute in Morse code,” he recalls,“but it bumped up to 20 words in the UK. I’ve built a life-sized model Morse communication setup in the basement.”

After time in Scotland, he and 700 others boarded the SS Pasteur and spent two months sailing to the Cape of Good Hope, then to Aden.“Somebody goofed, ”Trevor says.“We were supposed to go to Burma but were dumped in Cairo.We had no notion we were going to North Africa.” He was attached to the British Royal Air Force with about 100 other Canadians, a few Australians and New Zealanders, but was scuttled all around the fighting between the Allies under Bernard Montgomery and the Germans under Erwin Rommel. “We moved continually,” he says.“It was a shemozzle.Tents, dust, sand, fleas and crickets. They assigned me to the American forces, who didn’t use Morse code. No keys in the planes to start with.Very insecure.” “The Americans wanted to fly at night,” he continued.“But their exhaust trails lit up like Vegas. So they changed their tactics.”

He spent 18 months in the desert, variously stationed in Egypt, Libya, Tunisia and later, Sicily. Crouched in a small gun turret attached to the belly of American B-25 bombers, he handled two 50-calibre machine guns and the Morse code key.

On his fourth mission, January 2, 1943, his plane was hit and ditched in the Mediterranean while he signaled their location. Somehow, he escaped from the belly turret through a dinner plate-sized window and survived with six others in a dinghy for 30 hours.

Altogether, Trevor flew 55 missions— while the usual limit for gunners was 25-30 missions. During his 55th bombing run, an inexperienced colonel wanting flight pay missed the Italian target twice and then got lost. Trevor’s Morse code requests for help got them back to Sicily. The next morning, he visited the colonel. “Sir,” he said, “I’ve had enough.” (He tells me this story in his modest, understated way. Today, he’d be called a hero.) After flying to Cairo, he found the Canadians were clueless about what to do with him, but they released him from the combat area; Trevor went home to Victoria via West Africa, Brazil, Curacao, Miami and Ottawa.

WHILE IN NORTH Africa, Trevor, like all military men, thirsted for mail from home. Among the letter writers was Florence, aka Flo. “Our fathers were part of a small lending circle in Victoria and she wrote me regularly,” says Trevor, “mind you, it wasn’t romantic. But sometime during my desert sojourn, I asked her to marry me. She said yes.”

They married in 1944 after Flo finished her Victoria College studies; the marriage lasted 73 years. “When Hitler was defeated, we were released and every soldier was looking for work,” he recalled. “So after a few months, I went back into the Air Force and was posted in the Queen Charlotte Islands and Ottawa, teaching flight simulation for pilots.” Later, he and his growing family of two boys and two girls were stationed around Canada while Trevor flew all over the world in Dakotas and North Stars operating the radio while supplying the bases along the Alaska Highway and transporting dignitaries. He also served as radar fighter controller on several bases, retiring from the Air Force in 1960.

THE NEXT PHASES of Trevor’s life revolved around the sea. In 1961, he took the job of assistant lighthouse keeper and he, Flo and their four kids relocated to Lennard Island, near Tofino. Their government-issued home was on the verge of dereliction, cold and without running water. Electricity came on at night when the lighthouse operated and the Andersons turned night into day, with the children studying and Flo doing her household chores. In her autobiography Lighthouse Chronicles, Flo explained the senior keeper was a vicious drunk. Perhaps because Trevor had trained for lighthouse keeper duties, he’d become a threat to those without formal training; suddenly, the Department of Transport informed him he was fired. The noxious senior keeper had written a batch of letters reporting Trevor performed his duties badly.

Trevor journeyed to Victoria to protest his dismissal. After a lengthy investigation, he was reinstated, then promoted and appointed senior keeper at Barrett Rock. The family became rock hoppers, relocating to McInnes Island in Milbanke Sound, then to stormy Green Island, the northernmost-staffed lighthouse in Canada. They called it an “igloo” as the incessant tempests created rotund— and treacherous—ice pillows on the beaches. The Andersons lived through two ice-sprayed winters until July 1966, when they transferred to Race Rocks, which became a true home. They stayed 16 years.

Besides staffing the lights, the Andersons worked with Pearson College students and their marine biology teacher Garry Fletcher (featured in PY October 2019) to investigate the nine Race Rocks isles, their unique ecology, the surrounding high-current waters and various forms of alternative electricity production. They helped Garry to establish Race Rocks as an Ecological Reserve—areas set aside to preserve exceptional natural features. At some time, Trev and Flo decided they needed a sailboat and vowed to build one themselves, despite their lack of boatbuilding knowledge and skills. They spent much time pouring over Chappelle’s Boatbuilding and reading books penned by such sailors as the Hiscocks. They also met renowned boat designer Bill Garden. Over seven years, they built their 56-foot ketch (42 feet without bowsprit and davits), Wawa the Wayward Goose, launching her in 1982. “I knew I’d figure out all the intricacies eventually,” Trev says. “Bill Garden was enthralled.” They learned sailing by doing, first cruising the Gulf Islands, and then circumnavigating Vancouver Island. In July 1985, they headed offshore to Hawaii, New Zealand, Tonga, Samoa, Fanning Island and Pago Pago. After returning to Victoria in 1987, they continued to live on Wawa for another eight years before returning to life on solid land.

Flo died in  2017, at 93 years of age. Having had her companionship for nearly three-quarters of a century, Trevor misses her enormously. “Being alone is hard,” he says. He continues to live in the 100-plus year-old house in Victoria’s James Bay (Flo’s parents once owned it). Although he spent more than 20 years in military service, Canada denied him a pension, as “the service wasn’t continuous.” Consequently, he doesn’t have much use for Remembrance Days or other veteran recognitions.

How does one live until 99 and still be upright? “My philosophy of life is to take things as they come,” Trevor says. “Don’t do what you can’t do. I don’t think much about it, I’m just here. I’ve survived an airplane crash, a car crash and a mangled foot. I don’t drink, quit smoking more than 50 years ago. I just continue to live, day after day.”

Backyard Tips

On the Pacific coast in winter, Townsend’s Warblers often investigate backyard feeders, most regularly when temperatures drop below freezing, to eat energy-rich foods such as mealworms, peanut butter, and suet.

  • Cool Facts
    • On the wintering ground in Mexico, the Townsend’s Warbler feeds extensively on the sugary excretions (known as “honeydew”) of scale insects. It’s such a good food resource that Townsend’s Warblers set up and defend territories around trees infested with the insects.
    • Townsend’s Warbler was first noted to science by John Kirk Townsend, an American naturalist who collected a male specimen near the mouth of the Columbia River in what is now Oregon, on April 16, 1835. His discovery followed a long cross-continental trek. Townsend was accompanied on this expedition by English botanist Thomas Nuttall. Dozens of western plants and animals bear the names of these early naturalists.
