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

August 23

Posted on by

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:

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.

Here are a few photos from today:

August 20 – Two Pods of Transient Orcas!

Posted on by

Wind: W at the beginning and end of day, NE mid morning to early afternoon, 4-18 knots
Sea State: calm
Visibility: 0-10 NM
Sky: fog in morning, clear in the middle of the day, overcast in afternoon, rain in evening
Temperature: 12-17 °C
Atmospheric CO2: 412.15 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

There was a lot marine mammal activity today. At 11:00, two pods of Bigg’s transient killer whales were in the ecological reserve. One pod appeared to have about six whales. The other pod appeared to have three. Both pods spent a lot of time around the South Islands. A nearby whale watching boat captain mentioned on the VHF radio that the orcas were two families most likely having some social time. They were probably having a good meal too. I didn’t see any hunting happening on the surface. Transients eat marine mammals like seals. I did see a lot of harbour seals not taking any chances, huddled together on nearby rocks and around the east bay beach, looking towards the areas where the orcas were swimming. The transients stayed around until at least 3:30.

See the photos below for views of the orcas and other sights from today:

August 18 -More Sea Lions

Posted on by

Wind: W 15-29 knots
Sea State: up to 0.5m chop
Visibility: 10-15 NM
Sky: clear in morning, partly cloudy beginning in early afternoon
Temperature: 14-19 °C
Atmospheric CO2: 412.58 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The groups of steller and california sea lions around the main island and on Middle Rocks have all increased in number. There were two noteworthy sea lions today. In the afternoon, I noticed a lone steller sea lion near the end of the jetty. It had a white and red flasher (fishing lure) hooked to its mouth. Unfortunately, this is a sight that is occasionally seen here. Just last week there was another steller sea lion with a pink and yellow flasher. That sea lion (branded O-19) has not been spotted since. The flashers could have had a fish hooked on the end, which was eaten by the sea lion, or the lure could have appeared to the sea lion to be a fish. The sea lion this afternoon, left the jetty when a large boat went by. A few minutes later, it appeared on Middle Rock where a group of about thirty sea lions were hauled out. I will keep an eye on this sea lion. If it stays around for a few days, it could be a candidate for a rescue from the Marine Mammal Rescue Centre.

When I spotted the sea lion with the flasher haul out on Middle Rock, I noticed a steller sea lion branded 975R. The R means it was branded at Rogue Reef, in Oregon. This animal has been seen here before. See Ecoguardian Anne Stewart’s post from April 6, 2015. The steller was branded as a pup in 2011.

There were about twenty-five eco tour boats that passed through the Ecological Reserve today, some of them repeats. They appeared to be viewing the hauled out sea lions, harbour seals and the floating in the kelp sea otter.

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!

 

Hustle and Bustle / Pleasure Craft Violation / Census

Posted on by

Weather: 

  • Sky overcast, hazy, steady rain this afternoon
  • Visibility 15 miles this morning, < 2 miles this afternoon
  • Wind 0-10 knots NE
  • Water calm

Boats/Visitors: 

    • A whole boat load of visitors this morning! VP of Pearson College Tyrone, Alum in residence Norbert and friends to advise on our solar panel system, a desalinator consultant (in preparation for the new desalinator!), and an insurance appraiser.
    • Fewer whale watching boats this week, but we have been concerned about the frequent use of flash photography and its possible effects on the wildlife.
    • Greg also made another trip to bring us some water this afternoon.
    • Yesterday we watched a pleasure craft approach the sea lions near our jetty and throw some kind of food at them (some of it hit the sea lions). We were able to capture them scaring the animals, who stampeded into the water. They hovered to take photos and unfortunately pose with their open alcohol. Even more unfortunate, the bait that we saw being thrown at the sea lions previously and perhaps this time as well is not suitable for consumption, as many times it has been treated with formaldehyde.

Ecological: 

  • Many sea lions now, and unfortunately a few that are injured. Aside from the two that we have mentioned previously, we have been finding more fishing hooks scattered around and a sea lion appearing to have a nasty wound possibly caused by an embedded fishing hook.
  • This afternoon we also noticed a sea lion with a propeller inflicted gash on his head. He seemed to be dazed or perhaps concussed due to the injury. Normally the sea lions are skittish and make a ruckus if we get too close, but this one didn’t react to our presence and seemed notably lethargic. We were concerned that he might fall victim to the injury, but approximately an hour later he seemed more alert, reacted to our presence, and seemed to be doing okay.
  • We reported the tagged sea lion to the researchers in California and were excited to hear that they have some information about him and his early life. We hope to be able to share more soon! This little guy has already swum almost 1500 km from his birth place, Ana Nuevo CA.
  • Yesterday there was quite a bit of smoke caused by controlled burning taking place on the nearby DND land. They burned 20 hectares of Gary Oak habitat to protect the species (from invading conifers) and and prevent spread of invasive plants.

Census:

  • 350 sea lions
  • 50 harbour seals
  • 1 elephant seal
  • 40 cormorants
  • 60 adult gulls, and some chicks (they are too hard to see from the lighthouse)
  • 4 geese
  • 20 turnstones
