Making Sense of the Census.

The sun shone through a bit more today even as clouds and much needed rain continued. West winds blew at about 10 knots most of the day as the clouds were pushed steadily inland. The barometer is now back up to where it was last Friday before the big nose-dive into Saturday’s storm. The forecast looks a little brighter for Friday and Saturday before a return to wet and cool.

Whale watching activity in the Ecological Reserve was very subdued today as the black and whites moved north and east yesterday. Only four visits by commercial whale watching boats were observed in the Ecological Reserve. One sports fishing vessel and a couple of rental boats also came through obviously oblivious to the speed reduction zone within the reserve boundaries .

Thursday is census day and here are the results of this week’s animal census.

Steller Sea Lion 497

California Sea Lion 522

Harbour Seal 81

Northern Elephant Seal 2

Sea Otter 1

River Otter 1 seen (probably more)

Southern Resident Killer Whale 7 (during count week)

Biggs (Transient) Killer Whale 5 (during count week)

Humpback Whale 1 just outside of reserve but may have transited border

Canada Goose 4 full time (2 adults 2 goslings) (24 visited once during count week)

Harlequin Duck 1

Double-crested Cormorant 11

Pelagic Cormorant 12

Brandt’s Cormorant 1

Black Oystercatcher 29

Black Turnstone 95

Ruddy Turnstone 1

Western Sandpiper 3

Kildeer 1

Dunlin 1

Glaucous-winged Gull 276 (193 – adults; 83 juveniles)

California Gull 61

Western Gull 1

Heerman’s Gull 26

Peregrine Falcon 1

Common Raven 2

Savannah Sparrow 3

It is of note that there have been no Pigeon Guillemots seen since I arrived. Last year there were chicks, still  being fed by their parents, on the nests in the rubble area just west of the jetty at this time of year and later. I am hoping that the river otters have not been visiting these ground-breeding birds and will look for evidence of what has been going on there.

Maintenance work was routine and the only other visitors to the reserve were the Pearson College students having their orientation by vessel. Courtney kindly delivered paper, which was appreciated as there was none.

ANIMAL CENSUS

July 9th Thursday: Animal census

The fog was still there pretty thick but around 11:30 it cleared up and we could go up the tower to do the census. We had a west wind and the forecast was a gale warning for the end of the afternoon.The wind at noon was from West at 24 knots and could go to 35 in the late afternoon. We saw a few Whale watchers boats around noon and we had no visitors. Water is getting colder under 12 degrees Celsius. Guy put a new VHF on the whaler.

The estimation of the population is:
Elephant seals: 3
Sea Lions: 180
Pigeon–guillemots: 80
Gulls: 450 (yesterday we could see a group of gulls with black winged maybe some west gulls)
Pelagic cormorants: 3
Geese: 11 (Today the smallest one of the family of 5 was not in the water swimming but looked lost alone in the island hanging around). They spend more and more time in the water.
Black oystercatchers :0

Bald eagle: 1 (they attack the colony almost every day once in the morning)

 

June 28th Animal census day

Formal procedure when you want to enter the water by a hot day: Guy observed
Chunk going in the water in the middle of the afternoon. In the same way as people when the water is cold and, he took his time and delicately with his ‘ left arm and hand ‘ he sprayed water on himself and only after that did he go in.

It has been a calm and hot day: no visitors no whale watchers. The day was busy with the animal census. Maybe because of the wind coming, the island was not so crowded :one couple of oystercatchers could not be found neither the small baby I saw when first coming back. Just a few pelagic cormorants and no harbor seals closed…
Slowly the wind raised and at 6h00 it was 30 knots: gale warning was in effect.

A Tale of T-Whales

Today the wind continued its westerly path, bringing fresh ocean air in through the central Strait of Juan de Fuca at 20 to 35 knots. The sky was mostly clear, with clouds forming in the distance, along the tops of the Olympic and Cascade Mountain ranges. The barometer continued the climb it started yesterday until late afternoon, reaching almost 1020 hPa., before starting to gradually drop as the sun descended toward the horizon. Gale warnings continue to be in effect and the forecast calls for a mix of sun and cloud tomorrow.

Five whale watching vessels were observed working in the Ecological Reserve today in spite of adverse weather conditions. They all moved carefully and at a respectful speed being mindful of the marine mammals (Elephant Seal, Harbour Seals, Sea Lions, Sea Otter) and nesting seabirds in the Reserve. The only other vessel observed transiting the Ecological Reserve today was the Fisheries and Oceans vessel, Cape Kuper travelling at a discreet 25 knots towards Victoria, in the go slow zone.

Ecological happenings described in some detail in my earlier logs continue. (Elephant Seals haul out, socialize, sleep and moult. Other pinnipeds haul-out socially. Glaucous-winged Gulls, Pigeon Guillemots and Black Oystercatchers mate, nest, lay, incubate and get territorial. Mixed species feeding flocks (fish balls) attract gulls on the water and kelp is still growing.)

Of note was the sighting of Biggs’ Killer Whales (Transients) in the evening. I counted six individuals including a large bull with a very triangular fin. The two whale watching boats closer to them reported seven or eight individuals including a young calf. As often happens with T’s, as they used to be known, we spotted them a couple of times and then they totally disappeared. They showed up again, with the whale watching boats “in tow” a mile or so to the east.

Alex and I came out on Second Nature last night with Chris. Christine and Guy returned to shore the same way. A big shout out to Chris for all his support.

There were no visitors and chores were routine, but more fun with company.
