Entangled Steller (still)

Posted on by

Over the week I’ve been here I’ve seen the same entangled Steller every day, usually on the same side of the island. Since he had been sighted so regularly we made a plan with Fisheries and Oceans Canada (DFO) and the Vancouver Aquarium Marine Mammal Rescue Society (VAMMR) to make the trip from the mainland to disentangle him.

The head veterinarian at VAMMR is the only person here in BC that is trained and capable of darting a sea lion with a sedative in order to remove whatever it is entangled in.

There are so many factors that go into planning and executing these response efforts.

  • First: the animal has to be seen consistently over a few days in the same spot. Sea lions are mobile and keeping track of them isn’t always easy. There is nothing worse than showing up to help an animal only to find out it is no longer there.
  • Second: the VAMMR and DFO teams both have to be available with adequate vessels. Disentanglements can require teams to lean over the side of a boat to access the animal so rhibs are preferred and often necessary.
  • Third: the weather and tide have to be rather ideal conditions. If a sedated animal is in the water you can’t risk a fast moving tide or swell – that’s not safe for anyone. Wind and rain are not only factors that can make it difficult to dart the target animal but they also make it near impossible to fly a drone – an essential tool in these rescues.

Basically, all of these factors need to line up on the same day in order for a response to be planned. That day was today! Both teams available, no wind, good tides, animal seen all week…well until Sunday.

I did not see the sea lion Sunday or Monday despite my best efforts and requests for vessels in the area to keep an eye out. The animal being in the area is of course the most important aspect and without him there is no disentanglement to be done. The response was called off last night, teams standing down until he was re-sighted – a very reasonable decision.

HOWEVER…Guess who was perched on the rock next to the jetty this morning when I did my morning walk around? Yep, you guessed it, our big ol’ Steller with a packing strap tightly wrapped around his neck, and I’m not at all surprised. This is a frequent and very frustrating occurrence in the marine mammal field and had the team come out today I’m sure we wouldn’t have been able to find him. That’s just how it works sometimes. 

What now?

From here, we continue monitoring and planning. We all know we want to help him, so as the Ecoguardian I will continue to let both teams know each day that I see him. We will all work together to find another day where we can tick all the factor boxes and get out here to successfully remove the entanglement. It’ll happen!

For now – here is a video of a recent disentanglement done by VAMMR and DFO so you have a bit of an idea what goes into it.

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.

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.

110 california sea lions
1 sea otter
290 harbour seals
1 Canada goose
7 pelagic cormorants
1,232 california gulls

There were a lot of eco tourism boats passing through the ecological reserve today. An outrigger canoeist paddled through the main channel in the mid morning and again in the early afternoon.

Tomorrow is my last day as the Ecoguardian. Mara and Kai are returning for a few months. I have enjoyed being back on this wonderful island for the past 17 days, learning on the edge where the land meets the sea meets sky. Race Rocks is a unique place that couldn’t exist without the work of Pearson students, staff, faculty, alumni and volunteers.

Here are some sights from around the island today:

August 22 – More Flashers

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.

Here are a few photos from today:

Blowing a Hooley

Posted on by

Wind: Yesterday 5-35 knots N to W; Today 25-35 knots W with gust of 44 knots
Sea State: up to 2.5 m waves
Visibility: 5-10 NM
Sky: overcast with clear patches today
Temperature: 7-12 C
Atmospheric CO2: 413.20 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The forecasted gale warning materialized right on time on Tuesday evening. Overnight and throughout today, the westerly winds were between 25 to 35 knots with gusts as strong as 44 knots. There are lots of whistles and creaks in the 1960’s house. The storm also showed a few leaks in the various outbuildings. The strong winds brought clear skies and slightly warmer temperatures. For most of the day, rainbows were visible to the north, between Rocky Point and Victoria.

Yesterday, even though it was stormy, several hours were spent working outside on various maintenance and month end tasks around the island, which was made easier due to the animals and birds being less spread out as they hunkered down out of the wind.

Today, four branded sea lions were recorded and reported to researchers, who study sea lion ranges and lifespans.

The island’s population of elephant seals is currently at seven. One recently came back from a solo retreat on the West Rocks. The four non dominant males appear to be keeping their distance from each other at cardinal points of the island. The alpha male is hanging out in the middle of the island with the mother and pup. This morning, two of the beta males had fresh wounds on their backs, suggesting a possible disagreement with each other overnight. The elephant seal pup is continuing to nurse. Pups gain a whopping 4.5 kg per day from their 35 kg birth weight. Between all those pounds the pup is packing on and the rain, no wonder its coat is looking less wrinkled.

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:
