Ecological Notes:

  • 4 Elephant Seal on the main island
  • The Male Beachmaster (Bernard), 2 Adult Females, and 1 weened Male “pup” (very large now!)
  • The last pup had grown to almost double the size he was when I got here, and  I had hoped to report he was doing well, but unfortunately the nature and the Beachmaster had other plans. The (female)pup passed suddenly about a week ago and was returned to the sea today. Samples were taken for analysis, including hopefully testing for DNA to check paternity.
  • 1 California Sea Lion noted with rope entanglement. He is surprisingly active for the depth of the wound. Reported to the Marine Mammal hotline.
  • On a more positive note, the Black Oystercatchers are paring off, and some Gulls are wondering around showing off nice clumps of grass they have collected to whoever will notice.

“See my stuff????”

Visitors:

  • A couple of visits from the shorefront coordinator, delivering groceries, parcels, diesel fuel, and parts for repairs.

Facility Work:

  • After a couple attempts to repair the existing connections from the outside line to the pump, it was decided to just replace and simplify the pipes ….. to a final success.
  • Repaired the VHF Antenna on the main house, applied tape to hopefully stop it from vibrating the threads free in the wind.

DND events:

  • On and off all week, except the weekend of course

Noted Vessel Traffic:

  • Several Ecotourism vessels enjoying the sights and sounds of the reserve.

Responsible viewing and educating

  • With the nicer weather, several kayaks and outrigger canoes have looped out around the reserve, experienced paddlers who all stayed out of the main channel in the reserve where currents can be strong.

 Noted Infractions:

  • Some private fishing very close to the reserve, but measurements with a laser rangefinder suggest they were just outside the 40M depth contour.

Weather Events:

  • A mixture of winds, but mostly light days with mostly sun for the last couple days.

Seagull Stones and Census

Posted on by

Weather Today: 

  • Visibility 10 NM
  • Sky overcast
  • Wind 10-15 knots SW
  • Calm seas earlier in the day, rougher later on – swells 1-2m high

Visitors and traffic: 

  • Some old equipment is being moved to land, so there have been a couple of runs back and forth to the college.
  • The usual 5 or so whale watching vessels daily, very few pleasure craft as the weather gets worse.

Ecological Notes: 

  • We have been seeing whales every day, both humpbacks and orcas!
  • We thought the sea lions were beginning to move along for good but they came back – it has been interesting to observe how suddenly it can go from a couple hundred hauled out to perhaps only 50. They must leave in the night as we have yet to notice it as it happens.
  • Unfortunately we have another sea lion hanging around that has plastic around its neck.
  • While doing some work on the jetty today I (Kai) noticed an interesting pile of small stones piled up in a corner of the railing. We often see seagulls, especially the ones that look younger, playing with rocks of the same size. They are usually together in a group of 2-4 and they’ll take turns moving a rock around, holding it in their beak, and trying to take it away from each other. It seems plausible that the seagulls placed the rocks there, we haven’t seen other animals interacting with each other and objects this way.

Some photos from the last couple of days:

Plastic band removed from neck of Greater Victoria sea lion

Entanglement injuries in seals and sea lions a regular occurrence at Race Rocks Ecological Reserve

A sea lion trapped in human garbage has a second chance at life thanks to the sharp eye of a lighthouse-dwelling ‘ecoguardian’ at Race Rocks Ecological Reserve near Metchosin.

Mara Radawetz and Kai Westby, who live in the island’s lighthouse tower and monitor the reserve on behalf of Pearson College, called in back-up support when Radawetz spotted a California sea lion with a plastic packing band tightly bound around its neck on Sept. 1.

Over the days that followed, the duo spotted the animal again and watched it expressing clear discomfort as a result of the appendage.

“We could see that it was suffering, he would continually scratch at the infected area on his neck,” Westby said. “It had cut through his skin and created a kind of swollen, wet wound.”

The Marine Mammal Rescue Centre (MMRC), assisted by the Department of Fisheries and Oceans, responded to the call for help, but it would be a few days before the rescue could arrive by boat.

Fortunately, the rescue team arrived Sept. 10 and Radawetz was able to again spot the injured sea lion using a high-powered magnification lens from the top of the lighthouse, where the duo does a daily count of the island’s furry, feathered and blubbery visitors, which typically number in the thousands.

“Being able to have that eye in the sky was instrumental in being able to successfully help this animal,” Westby said.

With a bird’s eye view, the pair guided MMRC veterinarian Martin Haulena to an area where he could prepare a dart gun with a tranquillizer. Rescue staff aided from the water and land, watching as Haulena crawled over the rocks and got into position, successfully tranquillizing the sea lion.

In addition to removing the plastic band, the vet installed a tracking device and took a blood sample.

Radawetz and Westby said they see a sea lion or harbour seal with an injury due to human impact roughly once a week – and many of those animals don’t have a happy ending.

“We often see not only plastic entanglements but fishing line injuries on the sea lions and the harbour seals,” Radwetz said. The pair said they often see pinnipeds – seals, sea lions and walruses – that have swallowed a fish still on a fishing line, a meal that can cost the animal its life.

“It’s not always possible for us to help them,” Radawetz said.

While one lucky sea lion was able to swim free, Westby and Radawetz hope the incident resonates with people.

Westby added, “I really hope by sharing some of what we see here we can remind people that their actions have impacts and we are seeing those impacts here in Race Rock.”

In September 2019, a sea lion with almost identical injuries was rescued at the Race Rock Ecological Reserve. That animal had a plastic band embedded roughly two inches into its neck.

August 26 – Ring-Necked California Sea Lions

Posted on by

Wind: W 5-28 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 0-10 NM
Sky: clear, fog in morning and evening
Temperature: 10-15 °C
Atmospheric CO2: 412.47 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

Two california sea lions were spotted today with ring-neck wounds. One appears to have fishing line wrapped around and cutting into its skin. The Vancouver Aquarium’s Marine Mammal Rescue Centre has been notified. Rescue Centre staff mentioned they were up in Powell River today successfully disentangling a young steller sea lion.

Here are a few photos from today:

August 22 – More Flashers

Posted on by

Wind: W 9-12 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 10-15 NM
Sky: clear
Temperature: 13-15 °C
Atmospheric CO2: 412.45 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

It rained heavily overnight, giving the windows and pathways a much needed cleaning of the built up bird poop. I have been able to collect run off water from the downspouts on the main house and energy building, which can be used in the pressure washer to clean paths and exterior walls.

This morning, two steller sea lions were spotted with flashers hooked to the left sides of their mouths. One appears to be the sea lion spotted over the past few days. The other has an identical flasher. The Marine Mammal Rescue Centre has been updated, as this makes three different stellers with flashers hooked to their mouths in a week and a half.

Annual Christmas Bird Count

Posted on by

Wind: Yesterday 5-10 knots W; Today 5-20 knots NE
Sea State: up to 1 m chop
Visibility: 10 NM
Sky: overcast with rain this afternoon
Temperature: 7 C
Atmospheric CO2: 412.60 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

December 28 is the annual Christmas Bird Count, which happens in thousands of locations across North America. It has been happening for twenty-two years at Race Rocks. This morning with the northeast wind and dropping pressure, the planned visit by the local bird enthusiasts was called off. But fear not, citizen science provailed. For an hour and half this morning, I searched for birds of all feathers as I walked around the island and looked out from the top of the lighthouse. I used binoculars, a spotting scope and the zoom lens on the camera to check out the shoreline, water and the rocky islets of the ecological reserve. I was able to spot 12 species of birds, some of which were not present when I did the weekly census two days ago. Here are the results and photos of the bird count:

25 bald eagles (5 juvenile, 20 adults)
1 fox sparrow
4 canada geese
2 ravens
6 harlequin ducks
208 double-crested cormorants
59 pelagic cormorants
281 thayer’s gulls (on the rocks and in the water)
48 mew gulls (near Turbine Rock and North Rocks)
18 surfbirds
42 black turnstones
4 black oystercatchers

Photos of some of the birds seen today:

In the past two days, I have seen two entangled sea lions. Yesterday morning, I noticed a large steller sea lion with a small rope around its neck. The rope appeared to be cutting into the underside of the animal’s neck. A short while later, I noticed a california sea lion with a cut on its neck from what appears to be a plastic strap wrapped around it. The Marine Mammal Rescue Centre and Department of Fisheries and Oceans have been notified. If the sea lions remain at Race Rocks, it might be possible for a rescue to occur. Both animals were seen again today. See the entangled sea lion and marine mammal rescue tags for past occurrences that were written about in the Log. Two other california sea lions were seen that appear to have healing wounds from something that was previously wrapped around their necks. The animals don’t appear to have tags on their flippers to signify they have been rescued.

The Canadian flag was looking a bit tattered, so I replaced it today.

Just before sunset today, there were four eco tour boats in the reserve. The boats were all close to each other, which usually means something interesting is nearby. Sure enough, a pod of five or six orcas were passing westward. They travelled along the north side of the ecological reserve, just south of Bentinck Island and the Department of National Defence base.

Here are some photos from the past two days:

Marine Mammal Rescue

Posted on by

On November 4th and 5th the Marine Mammal Rescue Team was here to help out a couple California sea lions that were entangled. They arrive on the 4th and after doing a thorough search around the island there were no tangled sea lions around so we were afraid they may have left the area but thankfully the team stayed the night and the next morning they were able to find two sea lions who needed some help getting the garbage off of their necks. The first animal was on the north east side of island up on the rocks and Marty was able to dart him without him fleeing into the water. His tangle was pretty bad but thankfully the team was able to help him out before it got any worse. I’ve seen him hanging around the same spot since he’s been untangled.

The second one was in a bit of a tougher spot he was already half in the water so he jumped right in as soon as the dart hit him and went for a swim. The dart was very helpful in making him easier to spot as he swam around until he was sedated and the team was able to get a hold of him to help him out.

Overall it was a very successful trip and I am so glad the Marine Mammal Rescue team was able to come out here and help these guys out. I have not seen any new tangles since and I’m keeping an eye out for the two that are on the mend.

 

Steller sea lion with plastic around neck rescued on Vancouver Island

PHOTOS: Steller sea lion with plastic around neck rescued on Vancouver Island

Rescue staff determined the plastic band cut the protected animal’s neck approximately two inches

A Steller sea lion is recovering after being disentangled from a piece of plastic that cut its neck approximately two inches.The male sea lion, weighing approximately 500 kilograms, was reported to the Vancouver Aquarium marine mammal rescue centre team after it was seen near Sooke with a plastic packing band wrapped tightly around its neck.Rescue staff, along with officers from Fisheries and Oceans Canada and a veterinarian from the SeaDoc Society, joined forces Monday at the Race Rocks Ecological Reserve to rescue the animal, which is protected in Canada as a species of special concern under the federal Species at Risk Act.

Since Race Rocks is made up of rough terrain and has strong currents, it took hours of jockeying positions for Martin Haulena, the head veterinarian at the aquarium, to dart and sedate the sea lion. Haulena did this from a distance using an air-powered dart containing immobilization agents.

Over the past two decades, Vancouver Aquarium head veterinarian Martin Haulena has helped develop a precise drug combination to ensure that sea lions can be safely freed, without harming itself or others. (SeaDoc Society photo)

The sea lion entered the water after being darted, which Lindsaye Akhurst, manager of the aquarium’s rescue centre said is a common response. Then, with the help of Race Rocks Eco-Guardians in the lighthouse acting as “eyes in the sky,” the team was able to spot the sea lion in some kelp and remove the plastic band that had cut into the animal’s neck approximately 2 inches.

Once the sedated sea lion was located in the water, the rescue team discovered that while the top of the plastic band was still slightly mobile, the bottom, or ventral portion, had cut into the animal’s neck approximately two inches. (SeaDoc Society photo)

A release from Ocean Wise said “the depth and severity of the wound indicated that the plastic had been there for some time.”

Team members tagged the sea lion’s flippers so if there are further reports about it rescuers will be able to identify the animal.

To date, rescue centre staff have rescued over 20 entangled sea lions.

B.C. surveys have documented hundreds more entangled sea lions in recent years, the release said, with some of the worst plastic offenders being ghost gear, including nets and ropes, and discarded trash such as the plastic packing bands used in packaging and shipping, which ensnare animals.

Not only are plastic items uncomfortable for marine mammals, Akhurst said, but the sea lions continue to grow while the plastic around them does not, which sometimes results in death.

Akhurst said Ocean Wise is working with the Fisheries and Oceans Canada on a stronger disentanglement program that specifically targets pinnipeds, a group that includes seals, sea lions, and walruses.

In late fall, a multi-day outing is planned that will focus on this problem on the west coast of Vancouver Island.

Sea Lion Rescued from Plastic Entanglement

Posted on by

A team comprised of the DFO and Vancouver Aquariums Marine Mammal Rescue (MMR) came out to Race Rocks on September 16th to help the entangled sea lions we’ve spotted over the last few weeks. Leaving from Pedder Bay at 0900, they arrived in two RHIBs at the reserve shortly after. After observing the struggling animals over the last while and communicating information with MMR, they were a welcomed sight.

Right away we spotted three possibly entangled sea lions from the lighthouse (unfortunately none of these three being the animals we photographed previously). We then landed the team of vet techs and veterinarian Marty at the jetty to assess the situation. It was decided that one of the sea lions resting by the water between the guest house and the helicopter pad was our best rescue candidate.

Marty and a videographer from Vancouver Aquarium approached over the helicopter pad from the direction of ‘Camera 5’. They got into position and a shot was taken, but the tranquilizer dart bounced and the sea lion fled into the water.

From the lighthouse we were able to follow its movements and keep the team apprised by radio. There was uncertainty about whether or not it received a partial dose of the tranquilizer as it floated in strange positions/patterns. Moving around Race Rocks to the water beside the solar panel/generator building, it hauled out again and another shot at it was lined up from one of the boats. The angle wasn’t quite right, and it again fled into the ocean and couldn’t be spotted. It was around 1400, and everyone took a break to have some food.

After this, everyone considered calling it off as it was getting late and we couldn’t locate the animal. At the last moment, with both boats ready to head back to Pedder Bay, it was spotted from the lighthouse (resting on the rock mound on the NW point of Great Race Rock)! Tranquilizing was attempted from water, but the dart bounced again and landed in the water and was recovered. Here’s a short video of that:


After that, it ended up too far from the water to try another shot by boat, so in a final effort the one boat landed Marty and the team again while the other stayed on the water to support. With no cover available between him and the animal, Marty had no choice but to crawl about one hundred feet in order to take the shot.

We were able to capture the following footage of the sea lion being darted, going into the water, and then after a tense 20 minutes during which a pod of transient orcas appeared in the reserve (who sometimes eat sea lions), it was found! The team proceeded to cradle the animal between their vessels and remove the plastic band. Then, they injected a reversal drug to reverse the tranquilizer before letting it go.

Everyone was relieved to have successfully helped an animal in need. We have suggested that future disentanglement efforts might have a better chance if extended to overnight stays in the guest house, and perhaps coordinated and executed in a more timely manner in relation to the animal sighting(s). This time we were unable to find the original animals that we had previously spotted, since it took quite a while to organize the rescue attempt. A big thank you to everyone who came to help this sea lion and teach us about their work!

Thanks to the rescue team, one more sea lion has a better chance of survival! (vet Marty holding the dart gun and dart used to tranquilize the sea lion)
