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

 

Big Winds, Monday’s Census

Posted on by

Weather:

  • Visibility: 15-40 NM
  • Today we discovered that on the foghorn sensor there is a visibility reading display. Normally we base this off of which landmarks we are able to see (Victoria is around 10 NM, North rock is 1 NM, Port Angeles is roughly 15 NM).
  • Sky clear and blue, a few white clouds
  • Wind 25-30 knots W
  • Sea state: Rough. Waves up to .5 m, white caps
  • A climb in humidity today after a relatively calm and dry weekend

Marine Traffic/Visitors:

  • No visitors to the island since Saturday (Greg)
  • Only a few eco-tourism boats today (very windy), but a steady trickle over the nice weekend. We have been seeing an average of 7 boats every day, not including pleasure crafts.

Ecological Observations: 

  • We noticed yesterday that the goose with a limp (affectionately dubbed “limpy”) is no longer here. We aren’t sure if it was attacked by an eagle or decided to move along (the 13 remaining adult geese are here).
  • We were happy to see an adult otter run across the jetty boardwalk yesterday, raising our hopes that the dead river otter seen with “Ollie” the sea otter last week may not have been one from under our shed (creating the possibility of abandoned young if this were the case).
  • The seagulls seem to have gotten even more aggressive as their young begin to venture away from the nest: attacking young of other gulls, diving at our heads, and attacking each other if their individual “territory” (the area around their nests) is invaded. We have to be extremely careful with our movements around the island to avoid scaring chicks into the open where they can be attacked.
  • Many small harbour seal pups today! They are particularly playful at this time of year as they learn to swim and fish with their mothers. We have been enjoying observing their movements from the top of the lighthouse where our presence doesn’t bother them and we can see directly downwards into the water around the island.

Monday’s Census:

  • 515 Adult seagulls (this doesn’t include chicks- they camouflage too well!)
  • 1 male elephant seal
  • 2 Adult bald eagles
  • 13 Canada geese
  • 33 Stellar sea lions
  • 72 Harbour seals (moms and pups)
  • 1 Black turnstone

 

 

 

The Animals Have Been Busy

Posted on by

Weather:

  • Sky clear, blue
  • Visibility 15+ NM
  • Wind 20-25 knots W
  • Sea state: rippled, whitecaps, small waves breaking at .5 m

A fun link! Our weather station data can be publicly viewed Here.

Marine Traffic/Visitors:

  • On Friday Greg and a plumber visited
  • It has been quite windy but we have continued to see 5-10 whale watching boats per day on average
  • Quite a few fishing pleasure crafts outside of the reserve closer to Pedder bay, but no issues with fishing in the reserve this week so far.

Ecological Observations: 

  • This week we noticed a pigeon guillemot carry fish into a crevice in the rock wall outside our back door. We are excited to keep an eye on it and see if it is nesting! We have continued to notice breeding pairs copulating and flying into/out of crevices around the island.
  • This week there are large amounts of shorebirds visiting.We have seen ruddy and black turnstones daily as well as the occasional sandpiper. The turnstones are particularly elusive and fly away before we notice them quite often.
  • An appreciated bird ID correction from Daniel: The bird which we photographed on June 20 was in fact a whimbrel and not a short billed dowitcher.
  • This week we have seen quite a few harbor seals with their pups swimming or resting on rocks. We haven’t seen any nursing, but they are still quite small (and cute!).
  • The goslings and two parents haven’t returned since we saw them leave by water last Thursday. There seem to be two more adult geese gone today. We wonder if the goose family left for the main island, as the seagulls have become very territorial and aggressive, or perhaps the geese are naturally beginning to leave as they do seasonally.
  • A steady increase of sea lions in the reserve this week. There are now both california and stellar sea lions, and a few younger ones mixed in with the huge stellars that appeared last week.

 

 

What a Windy Weekend! (seagull chicks, census)

Posted on by

Today’s Weather: 

  • Sky partly cloudy (thick fog until late afternoon)
  • Visibility 10 NM (less than 200 m until late afternoon)
  • Wind 30-35 knots W
  • Sea state: swells up to .5 m, whitecaps

Marine Traffic/Visitors: 

  • Not many pleasure crafts this weekend as it was very windy (up to 40 knots!).
  • Greg visited today to deliver supplies
  • More whale watching boats this weekend than we have been seeing, around 5 per day.

Ecological Observations:

  • The seagull chicks have started hatching! Only a few nests have hatched so far. We have observed the chicks asking for food and the parent not feeding them. We wonder if there is enough food available to support them all through this nesting season.
  • One of the first nests to hatch had 3 chicks, but now they are nowhere to be seen. We are observing with an investigative eye as nesting season progresses, as we observed many instances of adult birds cannibalizing each other’s chicks last year.
  • One of the four goslings was eaten by seagulls on Saturday afternoon. The remaining three seem healthy and strong.
  • Not many visiting birds this past few days, perhaps due to the high winds.
  • Many harbour seals hauled out on outcroppings during the notably low tides over the past couple of weeks. The young seal pups are still keeping close to their mothers but we have not seen any still nursing.
  • The oyster catcher chicks are growing at an impressive rate! They seem to be doubling in size almost every week. They are now old enough to venture away from the protection of the rocky areas and explore the intertidal with their parents.

Census: 

  • 2 Male elephant seals moulting
  • 500 Seagulls, handful of chicks
  • 16 Adult geese
  • 3 Goslings
  • 10 Adult black oystercatchers
  • 3 Black oystercatcher chicks
  • 56 Harbour seals

Throughout the week we also observed pigeon guillemots, eagles, and a pair of swallows. The sea lion who was here alone over the past weeks seems to have moved along.

April 11 and 12 – Weekly Census

Posted on by

Wind: yesterday W-S 0-32 knots, today W-SE 2-17 knots
Sea State: both days calm
Visibility: yesterday 10-15 NM, today 15 NM
Sky: yesterday partly cloudy then clear from mid morning, today clear
Temperature: yesterday 8-14 °C, today 7-14 °C
Atmospheric CO2: 416.33 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

The lawn in front of the house got busier this morning with nine elephant seals, two more than yesterday. A tenth seal, the pup, was near the jetty. The two new arrivals have green tags on their tail flippers. One is a male tagged C887. The other is a juvenile tagged G512 on the right flipper and E779 on the right. I will update the information on age and past sightings when I hear back from the researchers. The green tags signify the elephant seals were tagged at Año Nuevo, south of San Francisco.

[UPDATED April 13: I heard back from Dr. Patrick Robinson, the researcher from Año Nuevo Reserve. The elephant seal with green tags E779 and G512 was tagged as a pup in February 2019, where he was born at Año Nuevo. This is the first time the male juvenile has been spotted outside of Año Nuevo, where he was last seen as a weaner in March, 2019. The elephant seal with the green tag C887 is a juvenile male that was born at Año Nuevo in February 2017. He has been seen at Race Rocks in the month of December in 2017, 2018 and 2019.]

There was one boat seen in the ecological reserve on each of the past two days, a pleasure boat yesterday and a sailboat today.

Wind: yesterday variable 4-40 knots, today W 3-25 knots
Sea State: yesterday up to 1 m chop, today rippled
Visibility: yesterday 10 NM, today 15 NM
Sky: yesterday partly cloudy with rain in morning, today clear

I took soundings on all the water and fuel tanks as well as other notable measurements for the month end report. Here are some of the numbers. The desalinator produced 6,650 L of water, which was used mostly for pressure washing the buildings and other cleaning. 540 L of diesel was used to run the generator to top of the batteries, when there wasn’t enough sun to charge the solar panels. The generator ran for 141 hours over the month, for an average of 4.5 hours/day. There were 24 visitors (16 unique visitors) to the island over the course of the month.

No boats were seen in the ecological reserve over the past two days.

See the gallery below for views around the island.

  • A high concentration of harbour seals on Turbine Rock at low tide
  • A small midden of deconstructed mossy chitons
  • Five out of the six elephant seals going for a dip in the jetty bay
  • Elephant seal pup buddies
  • Another view of the post sunrise sunny rain, from inside the energy building
  • Canada geese reflecting pond
  • A post sunrise double rainbow, while it was sunny raining

Spring Census and Swimming Seal Pups

Posted on by

Wind: yesterday W 0-30 knots, today mostly W, SE in early afternoon 1-28 knots
Sea State: both days calm in morning, rippled in afternoon
Visibility: both days 10-15 NM
Sky: both days clear
Temperature: yesterday 6-8 °C, today 6-11 °C
Atmospheric CO2: 414.34 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

All three elephant seal pups were swimming near the boat ramp both yesterday and this morning. The middle aged pup has taken to a napping spot on the concrete between the boat ramp and the rocks.

When I did the census observations today, I was surprised there were only 84 pigeon guillemots. I counted twice to make sure. The little black and white birds with bright red feet appear to be everywhere around the shoreline and in the water around the main island. They are constantly moving about and making their high-pitched whistling call.

I had a great view of a sea otter this afternoon. While out in the boat taking a photo of the main island, I heard what sounded like a slapping sound on the water. I turned around to see the sea otter about 20 m from the boat crack open clamshells on its chest. The otter had a few clams lined up. I turned off the engine and watched the otter quickly eat a few clams, then repeatedly dive down and eat more.

Today, there were nine pleasure crafts, one sailboat and the Race Rocks station boat in the ecological reserve, the most boats of any day this year. A pleasure boat with five people stopped at the jetty this evening. Three people walked along the jetty to get a closer look at the elephant seal pup napping beside the boat ramp. I approached and drew their attention to the large sign that explains the purpose of the ecological reserve and that permission is needed to come ashore. They were very nice and asked a few questions about the marine mammals before they left. No boats were in the ecological reserve yesterday.

Census results from today:
4 elephant seals (1 adult female, 2 female pups, 1 male pup)
10 steller sea lions
82 california sea lions
1 sea otter
50 harbour seals
8 bald eagles (3 adults, 5 juveniles)
11 brandt’s cormorants
6 double-crested cormorants
19 pelagic cormorants
9 Canada geese
251 gulls (mostly thayer’s gulls)
8 black oystercatchers
1 whimbrel
26 harlequin ducks
84 pigeon guillemots
4 surfbirds
12 black turnstones

Here are some photos from the past two days:

Two short videos of the youngest elephant seal pup learning to swim in the shallow water. In the first clip, she appears to be playing with a little bull kelp. In the second clip, she is blowing bubbles. The sounds of many species can be heard: california sea lions, thayer’s gulls, black turnstones and pigeon guillemots.
