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

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.

 

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

Jeff Spears is coming to the Rock to relieve me for a few days, as I head to a meeting in Calgary.

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

A steller sea lion with the brand “966R.” The “R” signifies that it was branded in Rogue Reef, Oregon. 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.

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.]

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.

Animal Notes and Census

A few days ago we had two unusual visitors to our waters. Two Brown Pelicans (Pelecanus occidentalis) spent several days on Great Race and North Rocks. Brown Pelicans, though the smalles of pelicans, are enormous birds weighing up to 6 kilos and measuring up to 135 cms with a wingspan of up to 2.5 meters.

A visitor from warmer climes….

Northern vacation to Race Rocks….

We have had two other unusual visitors in the last week. I discovered a Barred Owl in the boathouse attacking a Starling (another recent arrival), and Pam our avid photographer friend from England got several pictures of Peregrine Falcons that came through hunting sparrows and starlings. Pam’s pictures can be seen at: http://www.flickr.com/photos/66339356@N00/sets/72157628747376295/

Another tagged e-seal showed up in the boathouse yesterday.

Might as well hang out somewhere cozy…
