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:
Three transients in the south channel with many harbour seals on the rocks, probably trying not to become the next meal for the orcas. The large dorsal fin has a distinctive notch on the back side, which could help identify it. DFO has a 127 page document photos identification for the Bigg’s (Transient) Killer Whales from BC, Northern Washington and Southeastern Alaska. I flipped through the photos, but could definitively identify the orca.

Three different species hauled out together on the south side of the island: steller sea lions, california sea lions and harbour seals.
An overlooked gull snack that was left on the path. It appears to be a juvenile herring.
While I was eating lunch in the house, I saw a different kind of marine mammals, a group of seven sea kayakers approaching from the west. The kayakers paddled around the ecological reserve and headed north.
Oystercatchers making noise
The steller sea lion with the flasher is still hauled out on Middle Rock with the flasher attached. Behind is another steller, who was spotted recently with a suspected shark bite on its side.
The steller with a suspected shark bite wound made a brief appearance on the jetty this afternoon.

Wind: W 19 to 33 knots Sea State: up to 1m chop Visibility: 10-15 NM Sky: clear Temperature: 15-21 °C Atmospheric CO2: 412.54 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)
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).
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!)
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.
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.

Ecological:
We found another goose nest yesterday underneath the back steps of the main residence containing 8 eggs. We noticed that the nest near the desalination structure has been looted by seagulls and abandoned.
The seagulls continue to arrive and establish their nesting spots. There are roughly 50% more gulls this week.
Two juvenile gulls spent yesterday in the reserve. We didn’t observe them catching or eating anything.

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.

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.

Recently, the harbour seals have been hauling out around the shoreline of main island and nearby shoals. In the winter, they only hauled out on the outer islands away from the boisterous sea lions.
More harbour seals
