August 19 – Fog

Wind: W 4-23 knots
Sea State: rippled
Visibility: 0-15 NM
Sky: fog in morning, clear in late morning, partly cloudy in afternoon, then light rain in evening
Temperature: 12-17 °C
Atmospheric CO2: 412.58 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The fog began to roll in after sunset yesterday. In the early hours of the morning just before 3:00, the fog got thick enough for the sensor part way up the tower to trigger the fog signal. Three high pitch blasts sounded every minute until 11:20, then the fog gave way to a clear sky.

The steller sea lion with the flasher from yesterday still has it hooked to its mouth and is still on Middle Rock, hanging out with a bunch of other sea lions. I spotted it through the partial fog this morning, but wasn’t able to get a good photo. This afternoon, it was facing away from the main island.

Greg came out in the late afternoon to deliver diesel. We are filling the various storage tanks around the island for the furnaces and generator, in anticipation for the cooler and darker months ahead. There will be more fuel delivered over the coming days, taking advantage of the calm seas.

Other maintenance tasks included trimming the plants growing over parts of the paths, cleaning the solar panels and using the chainsaw to buck up more firewood. I finally cut up a 15 metre log that I saw wash up in a winter storm. It was propped up on rocks in the East Bay.

August 18 -More Sea Lions

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.

313 harbour seals
1 adult bald eagle
1 Canada goose
3 pelagic cormorants
1256 gulls (approximately 2/3 glaucous-winged gulls and 1/3 california gulls)
4 black oystercatchers
53 pigeon guillemots
42 black turnstones
1 american pipit

There were many ecotour boats passing through the Ecological Reserve today and only a few fishing boats visible in the distance.

 

Foggy Days and Sea Lions

Weather:

  • Sky overcast, heavy to medium fog
  • Visibility 1 NM (less than 1 during heavy fog)
  • Wind 5-15 knots W
  • Sea state: rippled to small waves less than 0.2m

Marine Traffic/Visitors:

  • A small handful of eco-tourism boats came thought the fog today.
  • Over the weekend, Sunday especially, there were many small pleasure crafts and a few eco-tourism vessels

Ecological Observations: 

  • A pod of four orcas was in the reserve on August 6th! They stayed in the area for about 10-15 minutes before heading towards Pedder Bay!
  • The sea lions are returning. Over the last few days there has been at least a dozen hauled out on the north side of the island near the crane, with more on the outcropping rocks.
  • The seagull chicks seem to be growing faster every day – we’ve spotted a few that are beginning to fly short distances.
  • When we do our water sample from the jetty we see pigeon guillemots perching up on the nearby rock, always in pairs, and sometimes with fish. They are very tricky about waiting until nothing is watching to take food back to the nest!
  • The fog and the nesting birds keep us inside most days without a good view of animals. More pictures and a census to come as soon as we can see!

Census:

  • 40 California sea lions
  • 51 Stellar sea lions
  • 111 Harbour seals
  • 1 Elephant seal (male moulting)
  • 552 Glaucous-winged gulls (nesting, some chicks that are big enough to see included)
  • 388 California gulls
  • 12 Oystercatchers
  • 112 Black turnstones
  • 2 Ruddy turnstones
  • 1 Surfbird
  • Pigeon guillemots were not visible at the time of this census (very windy), but the numbers have been consistent from last week as they continue to care for their young.

A New Arrival

Today’s Weather Conditions: 

  • Sky overcast
  • Visibility 15+ NM
  • Wind 15-20 knots W
  • Sea state: calm, fast moving currents today (almost 5 knots)
  • Daily fog in the mornings and often late afternoon as well

Marine Traffic/Island Visitors:

  • No island visitors aside from Greg on Thursday with supplies
  • Quite a few whale watching boats today and yesterday (20+)
  • Not many pleasure crafts passing through the reserve, but many outside of pedder bay (especially yesterday)
  • We saw 3 whale watching boats just outside the reserve circle a small group of orcas and follow them under power into the strong currents earlier this afternoon.

Ecological Observations: 

  • Today we were joined again by elephant seal V173. She was also here in December and again in the late spring when we first arrived. Her left eye is a bit oozy and red, but it seems like it is still functioning properly and she is otherwise looking great! She must have eaten a lot of fish out there- she’s much bigger than the last time we saw her only a few months ago.
  • The seagull chicks have been wandering farther away from the safety of their nesting areas, and we have been seeing quite a few more deceased chicks on the ground all around the island. They are being killed by rival gulls protecting their territory and young. There are a few chicks with injuries from these attacks, such as broken legs or wings.
  • We found an eviscerated gull chick on our back step on Friday afternoon. It looks quite a bit like a chicken does when a mink kills them (head missing), so we wonder if this is the work of a river otter.
  • As mentioned above we observed a few orcas just outside of the reserve earlier today. We have also been seeing humpbacks passing quite far away in the straight.
  • The pigeon guillemot nest that we have been observing closely (near our back porch) has at least one chick! We carefully peeked into the crevice and caught a glimpse of a tiny puff of black downy feathers. We are excited to be able to watch their activity so closely from our window as they are very secretive with their movements typically.
  • The remaining male elephant seal has been venturing to other parts of the island as his moult is finishing up. He has been finding some creative places to wiggle over rocks into shallow pools heated by water spilling over sun warmed rocks as the tides rise.
  • We heard a surfbird’s call today while out near the jetty- it’s a very shrill sound, just like the second recording here.

Otter Observations, Seagull Takeover!

Today’s Weather:

  • Sky Clear, blue (very foggy in morning and evening)
  • Visibility 10+ NM (less than 1 during fog)
  • Wind 10-20 knots W
  • Sea state: calm, slightly rippled

Marine Traffic/Visitors:

  • Yesterday Greg visited to drop off some supplies, as well as on Thursday
  • Less than 10 whale watching boats per day recently
  • Minimal pleasure craft activity and the regular stream of fishing vessels, and larger ships

Ecological Observations: 

Due to amount of nesting birds and chicks, we’ve been going outside only when necessary as our presence seems to bother them quite a bit. Some of the windows facing the action have been getting, ahm… ‘fogged’ despite our efforts to collect rain water and scrub them when we can!

  • One of the two elephant seals molting has left the island, and the last pieces of skin are falling off in big dry pieces for the one remaining.
  • Seagull season is getting a bit violent: there are many deceased and dismembered seagull chicks around the island. We don’t usually see it happen, but we think that they are being killed by other adult seagulls protecting their territory and chicks.
  • While walking over the rocky area near the jetty to recover a significant amount of plastic that floated in, we noticed some pigeon guillemot eggs hidden in a rocky crevice! This is the first time that we have spotted a confirmed nest, although we had suspicions as we have been seeing them with fish and waiting for us to leave (before they carry it into their nest).
  • We found a pigeon guillemot near the jetty under camera five- it appeared to have been eaten by a bird of prey or perhaps an otter. It had been partially plucked of its feathers and eviscerated.
  • We’ve been noticing more harbour seal pups! We’re not sure if this is due to there being a increase in the total pups around, or we are seeing them closer than usual due to the low tides this week. We spot the pups with their mothers taking shelter from heavy currents in the more sheltered area between us and rosedale rock.
  • Yesterday we noticed that there were quite a few dead seagull chicks dragged underneath a diesel tank waiting for removal near the jetty/crane shed. We looked under the walkway where we often see the river otter duck through the rocks, and there were quite a few there as well. This explains the cacophony we sometimes hear at night!
  • We were contacted by an eco-tourism company who shared with us that they had spotted “ollie” the sea otter holding the body of a river otter. It sounds like he has been noted as particularly territorial before, so this is not a surprise, although this is the first time we have heard this during our time on Race Rocks.

We’ve been saving the fresh water that drains from the firehoses after pumping from Second Nature’s tank, and using it to fill the pressure washer tank. We can use this to mist the panels and scrub them by hand to remove the seagull waste that builds up so quickly this time of year. Every little bit of sun counts!

Sunny Monday, Census

Today’s Weather:

  • Sky clear, blue
  • Visibility 15+ NM
  • Wind 15-20 knots W
  • Sea state: rippled, whitecaps

Marine Traffic/Visitors:

  • Today Greg visited for maintenance tasks
  • Quite a few pleasure crafts out today, but only a few passing through the reserve with no issues.
  • A steady trickle of whale watching boats today, especially just outside of the reserve where we spotted a humpback whale midday. We have been observing quite a few vessels cutting the paths of whales moving through the area, or driving over the location where the whales last surfaced.

Ecological Observations: 

  • Many shorebirds migrating this week. Today we counted 150 black turnstones! There are a handful of surfbirds mixed into the flock, which has been resting on the rocky beach area on the east side of the island.
  • The seagull chicks are growing quickly! They are starting to develop flight feathers and strengthening their wings by flapping them as if they are trying to fly. The last of the eggs seem to have hatched now. We noticed that one egg did not hatch in a nest where the eggs were stolen and the seagull had to re-lay later than usual. As the little ones become more adventurous their parents become more protective, diving at our heads and sometimes attacking each other if another gull gets too close.
  • We have been observing the pigeon guillemots pairing behaviors and wondering if they will nest here this year. We have spotted them carrying fish into crevices in the rocks, but we haven’t seen any nests inside the rocky areas (yet!).

Census:

  • 150 Black turnstones
  • 50 Pigeon guillemots
  • 10 surfbirds
  • 1 Bald eagle
  • 1 Cormorant
  • 11 Stellar sea lions
  • 760 Adult gulls
  • 56 Harbour seals
  • 2 Male elephant seals
  • 12 Canadian geese

Bird observations and census

Weather:

  • Visibility 8 NM
  • Sky clear changing to some cloud cover later in the day
  • Wind 10-20 knots W
  • Sea state: waves up to .5 m
  • We had an interesting ‘burst’ of fog around 1700hrs: while outside we noticed the wind picking up quickly and a fog front moved over us such that we could see the edge of it pass overhead – the fog horn went off for maybe 5 minutes, and then the fog disappeared as fast as it came!

Marine Traffic/Island Visitors:

  • Greg visited today
  • There have been some eco-tourism boats, about 5 so far day.
  • Some private vessels: mostly staying outside of the area and fishing, a couple of them came through and looked around.

Ecological Observations: 

  • We noticed a pair of pigeon guillemots mating on the rocks above the jetty today, this is the first time we have observed this.
  • Also near the jetty, the oyster catcher chick living in and above the intertidal area is growing quickly – it moves fast and sometimes strays away from its parents but cannot fly yet. It is still relying on the adults for food.

Census:

  • 13 geese
  • 12 oyster catchers
  • 3 oyster catcher chicks
  • 142 harbour seals
  • 2 elephant seals
  • 442 seagulls
  • 2 sea lions
  • Roughly 40-50 pigeon guillemots – these are hard to count!

Spring Showers Brought New Critters!

Weather: 

  • Sky overcast
  • Visibility 10 NM
  • Wind 10-15 knots W
  • Sea state: calm

Boats/Visitors: 

  • One pleasure craft fishing within the reserve today. They did not have a visible number so we were unable to report to DFO.
  • Yesterday Greg brought water which we pumped into our storage tank

Ecological: 

  • Today a large male elephant seal arrived! He is huge!
  • The smaller female elephant seal has returned for a bit more R&R
  • There are now goslings! There was one nest behind the boat shed which we did not see before. This morning we noticed two little fluffy goslings peeking out. Adorable!
  • The oyster catchers have begun to lay eggs
  • The seagulls are also laying eggs in full force. The nests are becoming fully established all over the island. They have become more defensive of their areas, which means we need to cover up! One of their favorite defense tactics is flying above us and trying to hit us with their droppings.

Returning Sun, Census

Weather: 

  • Visibility 15-20 NM
  • Sky partly cloudy clearing to blue sky
  • Wind 15-20 Knots W
  • Sea state: calm, rippled

Visitors/Marine Traffic:

  • No visitors
  • Yesterday we spotted a group of kayakers who had emailed to let us know they were coming: We tried to wave, but you were too far away to see us- hope you had a good paddle!

Ecological: 

  • The seagull population has skyrocketed this week, but still no fully constructed nests
  • The elephant seals have left now, aside from one. We anticipate that we may see a few large males in a month or so.

  • 16 Geese
  • 8 Oystercatchers
  • 39 Sea Lions
  • 40 Harbor Seals
  • 1 Elephant Seal
  • 1 Bald Eagle
