A Big Storm + Lots of Birds! (census)

Posted on by

Weather Today: 

  • Visibility 14 NM
  • Sky partially overcast
  • 30-55 Knots SW
  • Sea state: swells up to 2m, otherwise 3-4+ ft chop

Visitors/Traffic: Nothing other than a few fishing and shipping vessels in the strait.

Ecological Notes: 

  • We found another apparently healthy gull dead today; this is the fourth one since the beginning of the month. We now have two preserved for necropsy, which we hope to transport to land soon to be investigated. They have all displayed the same odd symptoms: weakness in the wings progressing to unable to move, wings dropping to the sides, and unable to make any sound.
  • This week there have been an incredible number of cormorants in the reserve! An underrated bird, they are very fun to watch as they waddle, preen, and fish.
  • We’ve been noticing some fungi popping up around the island now that we are into the rainy season! Photos below. These are in addition to the shaggy mane mushrooms we found last spring fruiting beside the composters.
  • Last week we spotted another “neck wrap”: a california sea lion with some kind of pollution material embedded into his neck. Unfortunately it seems that he is no longer present in the reserve, making a rescue improbable.

Census:

  • 4 black oystercatchers
  • 1 dunlin
  • 1 ruddy turnstone
  • 9 black turnstones
  • 3 surfbirds
  • 500 Thayer’s gulls
  • 17 Canada geese
  • 1550 Cormorants (wow!)
  • 2 bald eagles
  • 100 stellar sea lions
  • 502 California sea lions
  • 2 harbour seals

A Busy Week: Entanglements, Fall Weather

Posted on by

Weather:

  • Sky overcast
  • Visibility 1-10 NM – intermittent fog with a consistent layer of wildfire smoke
  • Wind 5-15 knots W
  • Calm water, rippled surface

Visitors/Traffic: 

  • One contractor visited the island yesterday, along with Greg and Lawrence the day previous.
  • Minimal tourism and pleasure craft activity (5-10 boats coming through daily)
  • Today Marine Mammal Rescue and DFO visited the reserve by water to look for entangled sea lions that had been reported to DFO. Unfortunately we were not able to spot the animals reported. Despite multiple vessels, the view from the lighthouse, and even a drone!

Ecological Observations: 

  • The increase in sea lions seems to be slowing and tapering off. Wherever there is available space, they haul out and fight for the best place to rest.
  • The elephant seal ‘Erica’ GE103 is still sticking around, and spends most of her time resting near the base of the jetty.
  • We noticed a robin hopping around on the grass yesterday but unfortunately didn’t get a picture.
  • We did see one sea lion with an entanglement injury on Sunday evening. It was the same one reported to DFO by a visitor in the reserve (boating past). We were not able to spot him again, and today we found the flasher which had been hanging from his mouth on the ground.

Break in Foggy Weather: Census + Pelican!

Posted on by

Weather: 

  • Sky partly cloudy, some sun and blue sky
  • Visibility 10-12 NM
  • Wind 20-15 knots W
  • Sea state: fast moving currents, still fairly flat despite wind

The fog horn continued for 20+ hrs each day until today. For most of this week we have had less than 100m visibility, making it impossible to see even a boat passing through race passage or the end of the jetty. At some points, we could barely see the guest house from the main residence! It can be difficult to focus and/or work productively during these long periods of fog, as the fog horn sounds three long high-pitched “beeps” every 45 seconds. More info on the history of Race Rocks foghorns Here!

Visitors: 

  • There have not been any visitors to race rocks since Monday when Greg and a contractor stopped in briefly.
  • There have been 1-2 tour boats in the reserve daily, but we can often hear them before we see them in the fog. The sea lions are easily startled by them because of the limited visibility, and sometimes when the boats emerge from the fog the sea lions run into the water.

Ecological Observations: 

  • The sea lions have officially taken over the island! We have been dutifully repairing the electric fences daily to keep them from damaging the buildings and especially from disrupting the burial cairns.
  • There have been an incredible amount of interesting birds to observe this week, despite the weather. Today we saw a pelican while enjoying the sunshine right from our back porch! This is a new sighting for us at Race Rocks and we were quite ecstatic.
  • On the note of bird sightings, we are hopeful for the installation of a new bird tracking device on Race Rocks sometime soon which will allow us to view migratory birds passing through the reserve as it detects their tracking bands.
  • One of our favorite elephant seals, E103 or “Erica” has returned again. We were happy to see her looking healthy yesterday- she had been hiding behind the piles of sea lions, and we only saw her once we had shooed them to install more electric fencing.
  • Identifying gulls is incredibly difficult. Some of them look the same aside from a slight wing color difference or color of feet determining them as a separate species! We are wondering if the gulls we have been assuming to be non-breeding california gulls are actually thayer’s gulls. Back to the id books!

Census:

  • 96 Stellar sea lions
  • 383 California sea lions
  • 88 Harbour seals
  • 1 Elephant seal
  • 1 Sea otter
  • 52 Brandt’s cormorants
  • 1 Brown Pelican
  • 1 Oregon junco
  • 2 Fox sparrows
  • 15 Savannah sparrows
  • 1 Yellow-rumped warbler
  • 1 Short billed dowitcher
  • 14 Black turnstones
  • 8 Canada geese
  • 320 Glaucous winged gulls
  • 113 California gulls
  • 20 Heerman’s gulls

Successful Sea Lion Rescue!

Posted on by

Weather:

  • Sky Clear and blue
  • Visibility 15+ NM
  • Wind 20-25 knots NE
  • Sea state: swells up to one meter
  • Temperature outside: 19.8 C
  • Pressure: 1021 hPa (decreasing)
  • We have been seeing consistent fog in the late evening, lasting for an average of 2 hrs. The fog banks seem to move over us from Port Angeles.

Visitors: 

  • Marine Mammal Rescue and DFO visited yesterday (more on this below).
  • Steady flow of pleasure crafts and whale watching vessels over the long weekend.

Sea Lion Disentanglement: 

  • Yesterday Marine Mammal Rescue along with the support of DFO vessels and staff came to help a sea lion with a plastic packing band stuck around his neck. They were able to successfully dart the sea lion with a tranquilizer injection, remove the band, give him tracking tags on his front flippers, and take a blood sample. When this was done they injected a reversal drug to wake him up and with a little scratch he was back on his way!

Ecological Notes:

  • The seagull chicks have officially flown the coop! Only a few remain and we are able to move around the island again without bothering the nesting birds.
  • This year we have noticed significantly less trash left behind by seagulls than last year. Our best guess is that they had more food available to them this summer, which would also align with observing them regurgitating much more fish that the previous season.
  • The sea lions have been increasing in numbers every day. The new fencing material that Nick and Greg used seems to be working much better than the wire that we tried last year, preventing them from damaging the island infrastructure. We have been letting them rest on the jetty this week but we will soon need to install more fencing in preparation for student visits.
  • Yesterday we found two turnstones which appeared to have been killed by the gulls while we were investigating the area near the codar antenna (SW Great Race Rock).

Wildlife Changing with the Seasons

Posted on by

Weather: 

  • Sky: clear and blue
  • Visibility 10-15 NM
  • Wind 20-25 knots W
  • Sea state: .5 m chop

Visitors: 

  • No island visitors
  • A small number of eco-tourism vessels (only one today).
  • We were saddened to hear this week that a fishing boat we have often seen pass by, Arctic Fox II, sank in rough seas on Tuesday, claiming 2 lives. An article Here.

Ecological Observations: 

  • The seagull chicks continue to practice using their wings, hopping and flapping in the wind. It can be quite comical to hear them “peeping” as they did when they were just hatched- they are nearly the size of their parents now!
  • The harbour seal pups get cuter by the day. We were lucky to catch one nursing this week from the lighthouse (photo below).
  • The sea lions population continues to grow, with a notable increase this week on Main Race Rock. We will need to put the electric fence back soon to prevent them damaging infrastructure.
  • We have been enjoying bird watching this week as migrations continue and the pigeon guillemots are raising their young. There have continued to be very large numbers of black turnstones on the E shore.
  • This week we have also been visited by a handful of ruddy turnstones, and one whimbrel (thank you Daniel for the ID help!)
  • The one male elephant seal is still here. He doesn’t seem to be actively moulting anymore, aside from a tiny bit of remaining skin around his neck. He spent the entire day yesterday drifting and napping in the peaceful and sheltered jetty waters. We have not seen V173 in quite some time.
  • We find a lot of joy in watching the elephant seals move from higher ground down the jetty ramp and into the water. If you are not familiar with their undulating movements, this video is an excellent example. It’s a lot of blubber to get off the ground!
  • We spotted one sea lion with a fishing flasher hooked onto his face a few days ago. We haven’t seen him since but we are hoping that we will, so a rescue attempt can be made to remove it.
  • We also saw a sea lion with what we thought could be an infected brand. We sent a photo to a wildlife officer in Oregon who tracks these branded sea lions and he shared with us that it is likely a shark bite!

 

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.

Steller sea lion with plastic around neck rescued on Vancouver Island

Posted on by

From The Goldstream Gazette BC LOCAL NEWS

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.”

In between darting attempts, the Vancouver Aquarium marine mammal rescue team had to pause rescue efforts due to the presence of Southern resident killer whales from J and K pods. (SeaDoc Society photo)

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.
