Weekly Census of Race Rock’s Megafauna

The wind blew about 10 knots from the north.  The barometer rose overnight from 1009 hPa to 1013 hPa as the sun set at 16:29, beginning to drop in the evening.  The sea was rippled.  The sky was mostly overcast with some breaks of sun and occasional light rain showers.  It hasn’t rained here during the day (possibly at all) in about two weeks.

There was one whale watching boat seen in the reserve today.  It spent a lot of time near the southern side Race Rocks, where the whale watching boats don’t usually go. Three small grey inflatable military boats sped around the edge of the reserve at 15:00, coming within less than a hundred meters of the islands.  After their circuit, they headed back towards the navy base.

Here are the results of the weekly census:

Steller Sea Lion: 263
California Sea Lion: 208
Harbour Seal: 7
Northern Elephant Seal: 5
Bald Eagle: 4 (2 adults, 2 juveniles)
Canada Goose: 9
Harlequin Duck: 3
Double Crested Cormorant: 44
Pelagic Cormorant: 147
Black Oystercatcher: 10
Gull: 396
Black Turnstone: 20
Rock Sandpiper: 3
Surfbird: 17
Fox Sparrow: 1

As always, there were variations in the numbers seen since last week.  There were fewer harbour seals.  I checked them throughout the day, the most I was able to see at one time were seven, scattered around the many small islands.  The tide was fairly high during the daylight hours, which tends to not be good hauling out conditions for the seals.  There were more smaller birds seen this week.  It was easier to spot smaller birds this week because of the lower wind speed.  I had a tough time distinguishing the rock sandpipers amongst the surfbirds.  While they look very similar, the surfbirds are a bit larger and have shorter bills.  See if you can tell the difference in the photos below.

 

Shift Change

The wind was blowing northeast this morning 20 – 25 knots, it dropped mid-afternoon for about an hour and then swung to the west. The west came on strong in the late afternoon and blew over 25 before settling down to 15 -20 knots. The barometer, which has been falling all day, started climbing at 19:00 and the forecast for tomorrow is looking better with light winds forecast.
There were only two whale watching vessels spotted in the Ecological Reserve today. There were no other vessels other than Second Nature dropping off Nick Townley the new eco-guardian and Pearson College student Riikka who is here to finish her project week.
The results of the census are as follows:
Steller Sealion 447

California Sealion 433

Northern Elephant Seal 16

Harbour Seal 17

Canada Goose 24

Greater White-fronted Goose 1

Double-crested Cormorant 324

Pelagic Cormorant 29

Killdeer 4

Glaucous-winged Gull 700

Thayer’s Gull 2400

California Gull 3

Western Gull 45

Heerman’s Gull 76

Savannah Sparrow 11

Most of the work today was packing, cleaning,  and training Nick in preparation for departure tomorrow.

Wild and Wet.

It was a wild and wet day at Race Rocks with waves breaking over the jetty and the feeling of the first storm of the season. Even though it rained fairly hard in the morning, there were only sprinkles in the afternoon, as the wind switched from northeast to southeast and then back to north. The barometer kept on its downward slide, started yesterday afternoon until mid-afternoon when it started to climb again. The climb may be short-lived though as the forecast is for more of the same.

There were no vessels noted in the Ecological Reserve today, but at least one came fairly close.

Great Race and the other islets that are not awash in the heavy seas, are almost completely covered with birds and mammals right now. It really is a natural haven.

With close to 900 seals and sea lions, thousands of gulls, and hundreds of other seabirds, it is surprising that there are still some unoccupied bits of terra firma around the house.

Double-crested Cormorants have significantly increased in number over the last two months.

The tagged Northern Elephant Seal 5850_6967 which I am going to call Gat (the noise he makes and Tag backwards) and his little buddy Flake spent the whole day asleep, pressed up against each other and the back of the boat house.

The animal on the right, Gat will be three years old in January. How old do you think Flake (on the left) is?

Something that most, but not all of the Elephant Seals have here, is extremely white mucous coming out of their noses. They are such amazing divers and spend so much of their life diving, that the default position for their nostrils is closed. Many truly marine birds and even marine iguanas have ways of conserving water and secreting salt through nasal glands and I am curious if Northern Elephant Seals can secrete salt that way? Will report back on my findings about the mystery of the white snot.

White mucus can be seen on the noses of many of the hauled out Elephant Seals.

I had no visitors today and could not go anywhere due to sea conditions but thanks to conference calling, I was able to attend a wonderful meeting at Government House in Victoria. The meeting was about a new initiative to empower youth stewardship in British Columbia, a legacy project of the Lieutenant Governor. Very exciting news will be shared in November. Yes, you will have to wait.

For outdoor adventure I swept walkways and cleared the marine railway of woody debris and seaweed, adding to the woodpile and enhancing the compost pile with some lovely bull kelp. Otherwise I did the regular maintenance to keep things going.

The Tie That Binds

It was another northeast day, with really not much happening weather wise. It blew NE about ten knots, was mostly overcast in the morning, with some sun in the afternoon. The barometer rose gradually all morning and then started to slowly slide after noon. It is expected that tomorrow’s southeast will bring rain, starting late tonight.

The whale watching boats were busy in the afternoon with Humpback Whales to the southeast of Race Rocks and more activity out to the west. A total of eight tour boats were seen in the Ecological Reserve.

Subi & Bltu
The census was challenging due to the numbers and species of gulls and the fact that both Steller Sealion and Harbour Seal numbers were lower than expected during the morning count, so they were re-counted in the early evening. I generally like to count Harbour Seals on the morning low tide but the tide wasn’t really doing much today. The evening counts were higher for both the Steller and the Harbour Seals. Two new Elephant Seals arrived today. They are both moulting, the smaller one hung out with the dual tagged three year-old, which appears to be staying on. The bigger animals may have gone back to Middle Rock as there were still six animals visible there.

Ring-necked animals as well as tagged and branded animals were also re-surveyed today. I am still working on the branding data from a month ago. Two of the ring-necked Steller Sealions that have been observed since August are still here and languishing as the plastic straps cut into the backs of their necks. I am putting out an appeal to the disentanglement crew again.

The second ring-necked animal ‘highlighted’ here is also branded on its’ left side 946R. I believe that it was branded at its’ natal colony which from the R should be Rogue Reef in southern Oregon. From the number it was branded after 2009 but I will find out more.

If it is not lying on its' left side this ring-necked Steller's Sealion is easy to tell apart from the others.

This is a bit gory but I hope it will inspire the disentanglement team to come to Race Rocks.

The Atlin Post passed by Race Rocks today but did not slow. Must have been in a hurry.

Did not do much maintenance today other than the basic cleaning, making water with the desalinator and electricity with the generator.

Wetter, cooler weather arrives.

There were definite autumn overtones to the weather today in spite of the westerly winds, which shifted over to the southwest a few times. First thing this morning a heavy fog came in and soaked everything. At dark there were ominous looking rainclouds to the west but the forecast actually looks like it is improving. After a week of sliding downhill, the barometric pressure actually rose today and that is a really good indicator of an improving trend.

There were only six whale watching boats noted in the reserve today and I couldn’t see any whales (for a change). The few recreational boaters left on the water stayed out of the reserve. The Oriole sailed past through Race Passage today, flying with the wind and tide.

A series of large military explosions rocked the island mid-day.

Oriole

Two Steller’s Sea Lions with Ring-necks were photographed today as was a Steller’s with a green flasher hanging out of its mouth. One of the ring-necked Steller’s is not yet badly wounded by the plastic strap, the other (see photos) has the strap cutting into the back of its neck but not yet the front. This animal likes to sleep about ten meters from my house and would be a good candidate for disentanglement.

There were no visitors today. Maintenance chores, other than making fresh water and electricity included cleaning in the boat shed, mending both houses’ fences, and keeping the weed-eater going. The weed-eater makes really good compost mulch.

What’s your number?

It was a day without fog at Race Rocks and as the westerlies continue, some serious clouds can be seen piling up on far horizons. The barometer rose all day, which bodes well for tomorrow but there may be a few needed showers.

It was a busy day on the water with 26 whale watching boats visiting the reserve. From the expressions on the tourists’ faces, they seemed to enjoy watching the sea lions. All the skippers were respectful except for two travelling together who did not heed the go-slow zone.

There were so many recreational fishing boats that I could only keep track of the ones who were in contravention of the DFO Rockfish Conservation Area closure which runs around the reserve at a 40m depth. Many of those fishing inside the boundary were in rental boats but some of the other speed boats were doing what they do best…speeding. The Pedder Bay Marina is really good about talking to folks who rent from them and informing them about the conservation area.

I looked for tagged and branded sea lions again today and can report another nine California Sea Lions and four Stellers’ Sea Lions bringing the total number of branded individuals sighted up to 29. Eventually we will know a bit more about their stories from those numbers they carry. There are also two Stellers with neck rings cutting into their flesh and one with a flasher hanging out of its’ mouth. There are individual Harbour Seals, as well as both species of sea lions with major wounds. Speaking of wounds, there were two new, (to me), very small Elephant Seals on the ramp today, probably young of the year, judging from the size.

A few Pigeon Guillemots are still carrying into fish into the large boulder area by the jetty. The chicks must leave for sea at night as I haven’t seen any on the water and most are probably fledged by now. Each day, there are more Pelagic and Double Crested Cormorants roosting on the southwest side of the island.

The desalinator worked for a couple of hours during the sunshine today, making fresh water thanks to the solar panels.

Month end inventory was conducted today with measurements taken of all the fuel, fresh water, and equipment run times recorded.

My other task was to try and stake out a small territory on the jetty so that I can come and go and do the sampling. The elephant seals are no problem, they just sleep as you pass, or open one eye. Keeping the more belligerent California sea lions off the jetty seems to be a losing battle and has made getting out to the end of the jetty to sample seawater, extra challenging.

Animal Census

Low winds today picking up in the afternoon/evening. Clear skies for most of the day. Forecasted winds of 15 knots for tomorrow morning rising to 30 in the afternoon.

Baleen whale this morning spotted feeding in the same place as yesterday evening, to the SW end of the reserve.

Anne continued with training today. James from Hybrid Plumbing came out to fix the water heater this morning. Changed cartridge filters on desalinator. Prepared for shift change.

 

 

Animal Census

Northwest winds dipping down to 10 knots midday and back up to 15 knots in the afternoon. Barometric pressure climbing since late Thursday. Forecasted fog for tomorrow and winds from 10 to 25 knots in the afternoon.

Animal Census:
272 Gulls
32 Guillemots
4 Elephant seals
381 Sea lions (Steller and California)
3 River otters
2 Double-crested cormorants
273 Harbour seals
13 Black oystercatchers

The otters appeared in the early evening again, taking at least two gull chicks. The sea lions, both Steller and California, have started making their way onto the main island. The electric fence is set up to deter them from the jetty, the winch pad (and hydraulic pipes) and the main residence.

We’ve had issues with one of the inverters in the generator room this week which have meant limited power, internet and phone access.

 

 

Animal Census and more…

Winds have been on a downward trend since Monday but since noon today have picked up to 35-40 knots. Barometric power dipped to a low of 1010 hPa Wednesday evening. We’ve had heavy fog until yesterday and today.

Few boats in the reserve this week (I suspect due to fog).

Two whale watchers today and 2 recreational fishing boats passed through the reserve today.

Animal Census (for Wednesday, 16 July):

256 Gulls
9 Pigeon guillemots*
2 Elephant seals
13 Steller sea lions
1 Double-breasted cormorant
9 Black oystercatchers
6 Canada geese
38 Black turnstones (Arenaria melanocephala)
2 Ruddy turnstones (Arenaria interpres)

*I only saw nine guillemots on Wednesday, 5 of which were flying away from the island. I don’t know the reason for the low number but Thursday I counted over 80 again.

I have not seen Cheeky since Tuesday, however, a new (very plump) female elephant seal arrived Wednesday afternoon. After female was on the jetty at ~1800h but seems to have swam away again. Chunk is still here. The river otters made another appearance tonight. Running in the same direction the adult led the two young otters with a gull chick in its mouth. Before going under the diesel holding tank the two juveniles started away at the chick. the Canada geese arrived Monday afternoon. Until today, there was a group of 5 that moved around together and an additional single goose that was seemed on its own. Today I counted seven and they were all together.

Monday morning I lost ethernet connection in the main residence. Jonathan came out Tuesday to have a look and he returned with two electricians on Thursday to fix the issue. Filled the batteries yesterday while they were here and got a tutorial on the Nikon camera.

Animal census

Overcast today. Some rain in the afternoon. West winds starting low and increasing during the day and then dropping off again in the evening. Barometric pressure staying just under 1016 hPa all day. A few showers and 15-20 knot winds forecasted for tomorrow. Yesterday there were over a dozen whale watching boats in the reserve. Today only 3 whale watchers. Yesterday there were 4 blasts from DND in the morning around 1000 and 1100h.

Animal Census (for today)

Today the two elephant seal males were sparring ALL day. They started fighting in the water near the jetty at 1100h and continued back and forth into the afternoon (around 1400h). When they eventually returned to land they continued sparring, mainly the larger pursuing the younger one. Even now, they are moving around each other cautiously.

Tried to hook up the VHF radio in the guest house today but had some difficulties with the wiring and the weather. Will try again tomorrow. Some continuing internet issues last night and this morning but hopefully they stay fixed for a while this time.
