Foghorn and tower updates

Posted on by

Ecological Notes:

  • Large female Elephant Seal came up to the centre haul out area on the Island. She appeared to be one of the females from last year. She spent regular periods ca.ling out, before leaving after 3 days ……. a pattern I have seen each time any single Elephant Seal has come to the reserve this season

  • Juvenile Golden Eagle still visiting occasionally
  • One morning there was an extra high number of eagles here….. 40+. I looked for new carrion or any other reason for there to be so many, but couldn’t find any.
  • California Sea Lion that had a band removed a while ago is around, and his neck appears to be healing well

Visitors:

  • 2 techs from the college
  • 3 techs from coastguard

Facility Work:

  • Pearson College IT installed new Starlink system at the top of the tower. Still awaiting implementation

  • Coastguard attempted to repair foghorn system but are awaiting parts now, and serviced the battery system for thew lighthouse
  • Cleaned the filter on the main house furnace, but detected a probably leak in the main fuel line
  • Received new files to re-work the chainsaw chain
  • Cleaned the rest of the outside walls of the student building, save for one area where I couldn’t position  the ladder safely by myself.(once the green is gone, the residue comes off after a couple rains)
  • Cleaned a small section of the roof, but found it pretty sketchy for a “larger” old guy to extend his reach that far above the ladder!

  • Daily attempts to keep the boat ramp clear of driftwood

Educational Visit, and Orca

Posted on by

Ecological Notes:

  • Steller Sea Lion photographed nursing what appears to be a yearling “pup”

photo by Ashley Warwick

  • 2 Orca hunting in the reserve, 6 more hunting south of the reserve. This is not uncommon behaviour, as the 2 inside can panic and scatter the seals and sea lions out into the deeper water
  • Juvenile Golden Eagle present 2 days in the reserve. (there has been one frequently sighted in the Rocky Point area since last fall)
  • Students conducted the animal census

Visitors:

  • In cooperation with Pearson College, 7 Students and 1 chaperone for the WestCoast Adventure College stayed for 4 days. Current Eco-Guardian taught classes in Marine Mammals of the Salish Sea, and did some Heritage Arts projects in the evening. In addition, students learned about Race Rocks, all operations out here, and helped the Eco-Guardian with projects …. especially projects like work on ladders, and moving logs that are difficult to do by himself

Facility Work:

  • Gutters cleaned on the Student House/ Science Center
  • Most paths, wooden stairs, roof of desalinator bunker, some exterior walls treated to remove algae
  • Paths pressure washed
  • logs stacked in the ramp area, pre-bucked and moved to the upper bucking area
  • More large logs salvaged and moved onto the ramp area
  • Weekly battery maintenance

DND events:

  • 3 days with occasional blasting, some delays when Orca in the pass

Noted Vessel Traffic:

  • Eco-tourism vessels
  • Cetacean Research vessel when whales present, and Marine Mammal Observer Vessel present blasting

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).

Wind: W 2-19 knots
Sea State: calm in morning, rippled in afternoon
Visibility: 15 NM
Sky: clear, partly cloudy in evening
Temperature: 11-16 °C
Atmospheric CO2: 412.58 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

There were not a lot ecological happenings to note from today. The sea lions are continuing to grow in numbers in the main haul out spots on the southwest side of the main island, southeast side near the lighthouse, jetty area, and Middle Rock. Stay tuned for the weekly census tomorrow to get the official numbers to see how the population has grown since last week.

I have been keeping track of the two steller sea lions seen recently with flashers hooked to their mouths. I only saw one this morning near the jetty. I thought I saw one which was possibly the same one on Middle Rock, although I couldn’t get a good look at it because it was facing away.

I transferred diesel to the furnace tanks in each house, in the ongoing effort to get everything stocked up for the colder months.

There were a lot of eco tourism and pleasure boats in the area, taking advantage of the nice weather.

Here are two photos from today:

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!

 

Entangled Sea Lion gets rescued at Race Rocks

Posted on by

The rope had his right flipper ensnared, and it was caught on a rock leaving him tethered on the island

On December 13, 2009, Ecoguardian Ryan Murphy reported to DFO that a sea lion on Middle Island was entangled in ropes. (See Ryan’s comments below) The ropes were snagged so it could not leave the rock. A rescue was mounted by DFO and the Marine Mammal Rescue Centre of the Vancouver Aquarium on December 16. This was the first time a sea lion had been successfully released from such an entanglement.

Further comments from resident marine scientist and ecoguardian at Race Rocks Ryan Murphy
: December 21 2009Ryan was interviewed for this article in the Goldstream Gazette: Daring Sealion Rescue at Race Rocks“Normally, neither DFO or the Vancouver Aquarium will intervene with entangled pinnipeds (seals and sea lions), but this case was special for a number of reasons.
1.  The sea lion was actually tethered to the rocks.  These animals are really tough and can often survive for years with their entanglements.  If tranquilized, these animals would take to the water and most likely drown before a rescue team could get to it.  This wasn’t the case here and so a rescue operation was a viable option.
2.  Steller sea lions (Eumetopias jubatus) like this one are listed as a species of special concern under SARA and as such are afforded a higher priority than other more abundant species like harbour seals and california sea lions.
3.  This animal was most likely spotted within 24 hours of its entanglement and was still in relatively good health.  Mike Demarchi of LGL who was on the island monitoring DND activity on nearby Bentinck Island and Rocky Point first spotted it on the morning of the 13th and his team and I were able to keep a very close eye on it during the daylight hours.  It was reported to DFO’s Observe, Record, Report (ORR) line (1-800-465-4336) and the Vancouver Aquarium Marine Mammal Rehabilitation Centre (at 604-258-SEAL (7325) or via the emergency phone at 604-862-1647).  A case like this on an offshore haul out would most likely have resulted in death by starvation, hypothermia, or drowning long before it was sighted.  In the 3 days between the first sighting (first photograph) and its successful rescue, this animal had further tangled its tether from about 10m to 3m and exacerbated the wound to its flipper.  The gale yesterday would have drowned it had it not been rescued.”
