Weekly Census of Race Rocks Fauna

The wind was gusting up to 33 knots from ENE overnight.  In the late morning, the wind settled to around 15 knots from the ENE, and has maintained that throughout the afternoon.  The gale warning for the Juan de Fuca Strait was lifted mid morning.  The barometer dropped slightly from 1018 to 1015 hPa, between overnight to the afternoon.

Two whale watching boats were seen in the reserve at 16:00.

There were a few differences noticed while doing today’s census, compared to last week. There were not as many smaller birds seen today.  The elephant seals are not hanging out near the jetty, where they have been for the past few weeks.  They are now a few hundred metres west, on Middle Rocks.  The harbour seals were easier to spot because they were basking in the sun on the many small islands that make up the ecological reserve.

Here are the results of today’s census:
Steller Sea Lion: 430
California Sea Lion: 359
Harbour Seal: 36
Northern Elephant Seal: 6
Canada Goose: 37
Double Crested Cormorant: 12
Pelagic Cormorant: 41
Gull: 756
Black Turnstone: 1
Savannah Sparrow: 1

A Mighty Wind’s a Blowin’ for Census Day

The barometer dropped all last night from 1015 hPa to 1002 hPa this morning, before it began to climb again towards 1008 by the end of the day.   The wind started from the northeast, but then switched to blow strongly from the southwest from mid morning onwards. The gusts reached 47 knots in the evening.

There were two whale watching boats seen in the reserve.

Once the fog lifted, the census was a bit easier to do. Then the wind blew up and most of the birds hunkered down on the leeward side of the island. I wasn’t able to positively identify all of the individual species of gull. Next week, I will strive to get an accurate breakdown of the number of glaucous-winged, thayer’s, california, western and heerman’s. There are a lot fewer gulls compared to last week, only 14% of the 3224 that were on the reserve last Thursday.

See the photos below for some of the noteworthy species and sights seen during today’s census.

Here are the results of the census:

Steller Sea Lion: 211

California Sea Lion: 404

Harbour Seal: 7

Northern Elephant Seal: 11

Bald Eagle: 1

Canada Goose: 24

Double Crested Cormorant: 14

Pelagic Cormorant: 56

Gull: 450

Black Oystercatcher: 18

Black Turnstone: 26

Surfbirds: 15

Dunlin: 4

Killdeer: 2

Savannah Sparrow: 2

Fox Sparrow: 1

I will add more information when I find out.  [Updated information from Pat Gearin with the NOAA: The Steller was branded as a pup at Rogue Reef, Oregon in July 2011.  It is a male and so far we have 9 resights from this individual, all from BC.  In 2011, he was sighted at Pachena Point once, and in 2012 he was sighted at Carmanah 8 times.]

A branded california sea lion with the brand “U596.” The “U” or “C” depending on which way you look at it, means that the sea lion was captured in the Columbia River Area. It was branded in Astoria, Oregon.  [Updated information from Matthew Tennis: U596 was branded on August 15, 2014 in Astoria. At that time he weighed ~193 kg. He was seen in Astoria for a few days following the branding and again in the middle of October. This is the first resight for this animal outside of Astoria. They have high site fidelity and being a relatively young animal, it is very possible he will be seen at Race Rocks for years to come.]

Fogimatrix.

The weather here was dominated by fog today. It lifted in an interesting way this morning so that you could see out and under the fog for several miles yet there was thick fog above, at very low elevation. The rising sun shone through this clear layer, creating a weird and wonderful lighting effect from below. By mid-day the fog had burned off and sunshine prevailed at sea level. There was still fog in the shipping lane and the tops of the Olympic mountains were visible. The fog flowed back in by mid-afternoon and thickened steadily after that, pushed in by a westerly fog wind. During the day there wasn’t much wind until late afternoon/early evening when it picked up to 15 to 20 knots from the west. The barometer continued its slow trend downward that started a few days ago and the forecast looks relatively good until rain on Friday.

There was a fairly steady parade of whale watching boats in the Ecological Reserve today. They were looking at Humpback Whales, Harbour Porpoise and of course the Sea Lions. Sixteen tour boats were noted although I may have missed some in the fog. One of the tour operators had the chance to see a really big (tyee) spring salmon swimming through the kelp forest.

There were sports fishers catching Coho, Spring and Chum Salmon to the south and west of Race Rocks and many sea lions were also busy catching salmon while at the same time helping to feed the gulls with their scraps, not out of any benevolence, just because they are messy eaters.

There are many gulls here now including Glaucous-winged, Glaucous-winged hybrids and Thayer’s gull which are challenging to distinguish. I look forward to doing the census first thing tomorrow to try and figure out how many of which species. The Heerman’s Gulls continue to benefit from sea lion salmon treats which they certainly can’t do where they breed in Mexico. I like watching them. They are very beautiful and have a interesting feeding behaviours that they may have learned from birds like skimmers where they live rest of the year. They fly with their lower bill hanging down just above the water and occasional skim the water with it, catching small prey.
There are many sea lions on the west side of the island now and the westerly wind carries the dusty grime from them onto everything in its path. The Savannah Sparrows feed in and around the sea lions.

These little Savannah Sparrows forage through the sea lion waste picking up morsels and probably a few parasites.

Elephant Seals have been hauling out on Middle Rock for over a month and now some are back on Great Race again. There was a small one hauled out on the northeastern side and a bigger one on the railway with the sea lions.

Washing the solar panels took a long time this morning. They were really dirty. I will do them after the census and it will probably take even longer, tomorrow as I want to shovel off the organic stuff that has accumulated before the electrician arrives to work on the panels. Today I readjusted to life on Race Rocks, finished the month-end report for September, did the seawater sample, made freshwater with the desalinator, ran the Lister generator and sorted photos as well as sea lion brand and entanglement data.

This entangled California Sea Lion has been spotted repeatedly since the end of August.

Killer Whales and Sport-fishers to the West

Another glorious day on the rock with good visibility, calm waters and a clear sky. The barometer rose gradually until noon and then dropped slightly. Barely perceptible outflow winds kept the fog out at sea and it looks like a similar forecast for Friday.

There was a lot of activity in the Reserve today with whale watching boats stopping by to see the sea lions en-route, back and forth between Victoria and the two pods of transient (aka Bigg’s) Killer Whales off to the west. The smaller pod had four individuals and passed close to the reserve heading west spending the day between Becher Bay and Beachy Head. A second larger pod was reported from further west near Otter Point by days’ end. A total of 37 tour boats were noted in the reserve and many more passed by at speed outside of the boundaries. They keep constant contact with the whales during the day and pass off to each other, on leaving the area.

A couple of recreational boats spent time in the reserve today, one photographing sea lions for several hours and the other jigging. The conservation area is bounded by the 40 meter contour, and no jigging is allowed. Jigging targets territorial fish such as rockfish and lingcod although you can catch coho that way too. The Conservation Area is enforced by DFO and is there to protect long-lived, territorial fish like rockfish and lingcod, so that their offspring can disperse to other areas with the currents. A Marine Protected area like Race Rocks becomes a source of recruitment of young fish to nearby areas that don’t have protection and this ultimately makes the fishing more sustainable.

It was census day today.
Biggs’ Killer Whales 4
Steller’s Sea Lions 243 (7 brands noted)
California Sea Lions 334 (7 completed brands noted, 1 incomplete)
Total sea lions both species = 577
Harbour Seals 142
Elephant Seal 1 (pup)
Savannah Sparrows 8 (seemed to fly off to the south across the Strait after visiting)
Double-crested Cormorants 11
Pelagic Cormorants 4
Black Turnstones 7
Sandpipers 5
Sharp-shinned Hawk 1
Glaucous-winged Gulls 99 (4 chicks still begging)
Heerman’s Gulls 5
California Gull 1
Black Oystercatchers 7
The Pigeon Guillemots were not spotted today so I assume that the chicks finally fledged and have headed off to sea. I will miss them. It is fun to watch them ride the currents and carry crazy-looking fish to their young.

There were no visitors today, although both Second Nature and Hyaku made multiple trips within a stone’s throw of the jetty, as part of student orientation week.

Gale

Strong Westerly gale all day. Intermittent rain and sun. Rainbows.

So far the new chimney for the wood stove is coping with the wind. It’s only been blowing up to 40-ish knots, but it’s still going strong.

There are a few Steller Sea lions still hanging out on the South rocks, although they spent the day in the water because of the foul weather.
This morning there were Pigeon Guillemots all over the end of the jetty.
The eagles are still around, feeding on the Sea lion carcass on the East beach.

Earlier today, while up in the lantern room, all of the Gulls lifted off the island because an Eagle flew over Great Race. So while it was blowing 30+kts, every bird on the island lifted up to the height of the tower and did their best to avoid the eagle. The eagle settled on the East beach and eventually the Gulls sat back on the ground. For those few minutes it was pretty amazing seeing all of the gulls and a great big Eagle doing their aerial acrobatics up at 100ft.

last day

Clear skies. Strong NE winds. Cold

Despite the winter weather, it is still a busy place out here in the reserve. The female elephant seals are hauled out on Middle Rock. The male Elephant seal is next to the Science House. There were lot’s of Oyster catchers, and way more Cormorants then I was expecting. There are also still quite a few Sea lions (~470) in the reserve; mostly on the South side of Great Race and South Rocks. I finally got a decent picture of a Savannah Sparrow today; and the Sandpiper stopped long enough to get a good photo so I could finally ID it.

Hummingbirds and Black Brants

Saturday, May 11, 2002
Good Evening
TEMPERATURE: Max. 12.0 C  Min. 7.3 C Reset 10.1 C
MARINE LIFE: 2 mature Bald Eagles today, still the 3 geese.There is a lot of bird activity and it is never quiet.Today we saw the usual gulls,oyster catchers,eagles,pigeon guillemots, geese, starlings, crows and savannah sparrows. An added bonus were the 2 humming birds that buzzed around for 20 minutes or so, always amazed to see them so far from the mainland but do see a few every year especially if the winds are light. A couple of black brant geese landed in the small bay on the east side of Gr. Race but did not stay long.
HUMAN INTERACTION: 5 pleasure craft and 13 ecotour boats, the last two enjoyed a beautiful sunset as they left the reserve.The D.N.D. did some blasting on the beach on Bentinck Island between 17:30 and 22:00 but only two blasts about 20:20 and 20:25 were big enough to have any noticeable impact here.The birds took flight en masse each time and took 10-15 minutes to settle down,it was getting too dark to see much beyond Gr. Race.
