Thursday is Census Day at Race Rocks

The weather was fine today with sunshine from dawn until about four o’clock. Winds were very light and the direction shifted around west, from northwest to southwest. As the barometers drops, rain is forecasted, southeast winds and then improving with only scattered showers by tomorrow afternoon.

The fine weather brought two small sports fishing boats into the Ecological Reserve today, both fishing and speeding inside the Ecological Reserve boundary.  My guess is that neither of them were aware of the Eco-Reserve and its protection from speeding and jigging.

There were three, whale watching boats in Reserve today and several others that passed outside of the boundaries. One of the attractions for the whale watchers were Biggs’ Killer Whales, also known as transients. The ‘T”s as they are known to the tour operators were travelling from west to east when I saw them and they passed very close to the seal haul-out on North Rocks before I lost them to view. It looked like four individuals. I saw a single, adult male Killer Whale two days ago, it was just a one-off sighting and I didn’t spot it again in spite of watching for quite a while. That one was also probably also a Biggs, just from the behaviour.

Today was Mega-fauna census day and here are the results.

What a difference between drake and hen. These 'white water' birds nest in the mountains by rushing streams and rivers.

It was a busy day with lots accomplished. I managed to get the weather station back up and connected to the Internet, thanks to good instructions. I have been on a bit of a wild goose chase, mapping out the nest locations of the Canada Geese. I troubleshot water loss problem (to no avail) and ran both the desalinator and generator. Sweeping the walkways and tidying up wood is ongoing. The census took quite a while and was totally enjoyable. This is such a special place, a real biodiversity hotspot especially underwater. What we see on the surface is like the tip of the biodiversity iceberg or the biomass (food) pyramid. All that biological activity can traced right back to plankton and sunshine that drives it. Sunshine made most of the fresh water today, thanks to the solar panels and desalinator.

Back on the Rock

Last night’s storm blew in just as shift-change finished. Nick Townley waved goodbye from Second Nature as Chris Blondeau, still in his dry-suit from the diving activity, pulled the vessel out into the tidal stream and headed her back to Pedder Bay.

Six students from Pearson College came out to the rock for the weekend and I started my shift with great company. Their goal was to catch up on studies (and sleep (my guess)) and to have their own experience in this gem of a biodiversity hotspot.

As we unpacked and settled into the two houses, heavy rain followed the black horizon moving in quickly from western Strait of Juan de Fuca. It was very nice to be snug inside as it was a wild night with heavy squalls. There were quite a few rattles and thumps that I didn’t recognize from last fall’s storms. Morning broke with gusts over 30 knots in the tower and alternate clearing skies and rainbows shone through and faded out on all sides. It was a white water scene with wind and current colliding in a frenzy. The barometer which had taken a nose dive Thursday and Friday, climbed back up to over 1024 HPa from Friday’s low of 1009. By noon, the westerly winds had dropped to 12 knots and the afternoon and evening was uneventful; overcast with showers and light winds shifting to northwest.

Although there was no fishing activity in the Ecological Reserve (ER) today, five wildlife viewing tour boats were noted. I was surprised by the number of both Northern and California sealions still hanging out and there were at least 75 Harbour Seals hauled out in the afternoon (not a complete count. I saw two pairs of adult bald eagles and numerous other birds including Canada Geese, Black Oystercatchers, Harlequin Ducks, Black Turnstones, Pigeon Guillemots, Double-crested and Pelagic Cormorants and an interesting mix of gulls. Many of the Glaucous-winged Gulls are already paired up and getting excited about spring. They are scattered around Great Race in all the places that there were nests last year. A much more condensed flock of gulls with about 100 birds was hunkered down in the lee of the rock on the west side of the science house. This flock was a mix of some unexpected visitors including Herring Gulls, Ring-Billed Gulls and even a few California Gulls, probably en route somewhere else. As dusk fell last night I heard the calls of Killdeer and it really felt like my home away from home.

It was great to get back up the tower again and have a good look around and for fun and more exercise, I started clearing off some of the winter’s woody debris accumulated on the marine railway. Greenlanders Hana and Malou joined in and we made it into a bit of a game, practicing our aim and strengthening arms. When we finished there was a stream of wood heading out to sea and we hoped that the whale watching boats were avoiding the busy tide lines.

March 19 – Last Day of Winter- Census

Raining
Wind: NE 4-14 knots
Air Temperature: Low 8.8°C, High 10.3°C
Ocean Temperature: 8.8°C

The wet conditions were helpful with cleaning some exterior walls and windows. The rain water cistern was filled up from the roof. The rain also helped wash away the algae and slime on the walls, along with some scrubbing.

The low light and rain made the census difficult. In recent days, there has been a much higher number of harbour seals hauled out on the rocks. The sea lions also spent most of the day in the water. It was not possible to distinguish between the species of cormorants on Turbine or Middle Rock.

There were no boats seen in the reserve today.

Sunny
Wind: 0-13 knots SW in the morning, NE from mid morning to afternoon and SW in the evening
Air Temperature: Low 9.9°C, High 13.2°C
Ocean Temperature: 9.0°C

Three Pearson students came to Race Rocks this morning. Karen, Sunny and Hanne joined Martin, who has been here since Monday.

The students did some work this afternoon: sweeping all 99 steps of the lighthouse and continuing the process of stowing the chopped wood in all the nooks and crannies of the buildings, to be used next winter to heat the main house.

There was DND blasting happening in the morning and early afternoon on Bentinck Island, less than 1km away from the ecological reserve.

Today’s high temperature of 13.2°C, as measured at the ground weather station, was the highest recorded since 2006, when the weather station was installed. A high of 14°C was recorded by the instruments at the top of the lighthouse.

Three eco tour boats visited the reserve. One boat came very close to a group of sea lions swimming and others hauled out on the South Islands.

The low tide of 1.1m at 13:52, exposed lots of species from the low tide zone into the air. The shore and tidal pools were full of life: mussels, barnacles, limpets and lots of other flora and fauna of the sea. The oystercatchers and shore birds were having a feast.

There were no small birds perching birds seen today. There are usually a few fox, sparrows, savannah sparrows and occasionally juncos and robins zipping around the island.

Here are the results from today’s Megafauna Census:
Elephant Seal: 1
Steller Sea Lion: 54

A great blue heron hung out on northeast side of Great Race for the afternoon. The oystercatchers are travelling around in pairs and are quite vocal. The gulls have spread themselves out around the island as they start to find nesting sites. Chunk returned to Great Race during the night. He spent the day resting against a boulder and the rock below the helicopter pad. The female elephant seal is relaxing in the same spots as yesterday, to the west of the main house.

Weekly Census

The wind varied in velocity and direction throughout the day.  Fog settled in overnight as the wind blew between 15-25 knots from the southwest.  In the daylight hours, the wind blew from the south and west between 7-32 knots.  The barometer dropped slightly from 1008 hPa to 1004 hPa.  It was overcast with patches of sun and rain throughout the day. The temperature reached a high of 12.8oC at noon.

There was one whale watching boat seen in the reserve, in the mid afternoon.

I saw humpback whales (Megaptera novaeangliae) twice today, both times from the kitchen window.  The whales were surfacing just south of Great Race Rocks, within the boundaries of the Ecological Reserve.  At 9:30am, I saw two humpbacks blow, surface and dive westward.  At 3:20pm, I saw one humpback surface and dive eastward.  I am not positive if they were different whales, so I counted them as two in the census.

Two branded steller sea lions were seen seen today.  76Y was a pup in 2002 when it was branded in St. George Reef, California.  443Y was branded in 2013, when it was a pup at Rogue Reef, Oregon.

Here are the results of the weekly census:

Humpback Whale: 2
Steller Sea Lion: 244
California Sea Lion: 216
Harbour Seal: 39
Northern Elephant Seal: 4
Bald Eagle: 5 (2 adults, 3 juveniles)
Canada Goose: 18

Birds and Sea Lion Brands

The wind was calm, not rising above 10 knots.  It blew from the northeast, swinging around to the south in the middle of the day, and settling on the east at night.  The barometer dropped from 1020 hPa to 1009 hPa, with a few short rises throughout the day.  The temperature reached a high of 10.8oC, at the ground station.

There was one whale watching boat seen in the reserve, just before sunset.

Pam Birley, the dedicated webcam viewer from the UK, spotted a peregrine falcon again this morning.  She was able to capture a photo of the peregrine from Camera 1, see below.  Pam thinks it’s a young one, because it has dark brown chest feathers.

I wasn’t able to spot the peregrine, but I saw two branded steller sea lions.  See the photos below of brands 205Y and 405Y.  The steller sea lion branded 405Y was born in 2013, at Rogue Reef, Oregon.  The steller sea lion branded 205Y is a female born in 2004 at St. George’s Reef, California.   The sea lion is well known to Pat Gearin, from the NOAA. Pat emailed me with some details about the sea lion: “She is an unusual animal because she has not returned to CA to have her pups but instead has settled at Carroll Island, WA where she has had at least two pups over the last 4 years.  I think the animal next to her in your first photo may be her juvenile which is still nursing.  Steller’s sometimes nurse their pups for over 2 years.”

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.

 

Harlequin Ducks

The barometer continued to drop from 1018 hPa overnight to 1009 hPa this evening.  Throughout the day the wind hovered around 14 knots from the northeast.  The sea was fairly calm.

There were two whale watching boats seen in the reserve today.

Four harlequin ducks were swimming near the end of the jetty this morning, when I was testing the salinity of the water.

Pinnipeds galore

There was a moderate breeze for most of the day.  The barometer dropped slightly throughout the day. There was a low cloud cover and occasional light rain.

There was only one whale watching boat seen in the reserve today.

Two juvenile bald eagles took the rocky perch on the South Islands that was occupied by the adult bald yesterday morning.  Occasionally one of the eagles would assert its authority over the gulls by flying around Great Race and sending the thousands of gulls skyward into a panic.

The pinnipeds are still occupying the reserve in large numbers.  Perhaps wanting solitude from the cacophony of sea lion barking, a lone california sea lion parked itself in the middle of the island for the whole day.

This afternoon, a group of five harlequin ducks were hanging out by the kelp beds to the west of the jetty.

It looks like I'm not the only one excited about the arrival of the new desalinator pump.  This California sea lion spent the whole day in the middle of the island.

It looks like someone else is also excited about the arrival of the new desalinator pump. This california sea lion spent the whole day in the middle of the island near the desalinator bunker.
