Shift change, census

Wind NE 15-20 knots becoming N 10-15 knots in the afternoon. Sky cloudy with periods of rain.

Courtney brought me out this morning in Second Nature to start a 3 month winter shift. She brought Nick back after I was able to get a quick update on systems and supplies.

Census:
California Sea lions: 20
Northern Sea Lions: 155
Harbour Seals: 1
Elephant Seals: 7
Cormorants: 70
Canada Geese: 5
Gulls: 252
Bald Eagle: 1
Harlequin Ducks: 2
Black Turnstone: 2
Sparrow: 1

3 Branded northern sealions observed: 870R, 347Y, and 975? (last symbol not visible)

Spent most of the day moving in, unpacking and getting reacquainted. We brought two full propane tanks out in the morning. Running diesel this evening.

The house is clean and things look to be in order here. Thanks to Nick, Ann, Jeff, Julie, and Courtney for their work out here since my last shift.

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
Crow: 2
Harlequin Duck: 4
Double Crested Cormorant: 61
Pelagic Cormorant: 142
Black Oystercatcher: 25
Gull: 411
Black Turnstone: 8
Rock Sandpiper: 6
Surfbird: 11
Savannah Sparrow: 2
Fox Sparrow: 2

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

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

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.]

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.

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.

Population Growth of Elephant Seals (Mirounga angustirostris) at Race Rocks, 1990-2014

The following is a draft copy of a graph I am working on to illustrate the growth of the elephant seal population at Race Rocks over the past few years. The information has been retrieved from logs of current and past Ecoguardians and photos and notes taken over the years.

Elephant  Seal census

one day of summer

Clear skies. Light wind. Glassy seas. 9’C

DND blast: 1055, 1 medium blast

DFO has decided to extend our contract for the recreation fishing count. It starts again on December 1st, and continues until March.

The Canada Geese returned today, hopefully they don’t stay long, and I would prefer it if they stayed off my paths. I was told that the Sea lions leave this time of year, but there’s no sign of it happening yet, with over 1000 Sea lions still in the reserve. Maybe it’s because we have had such a mild Winter, with very few storms. They are mostly out on the Cobble beach on the South side of Greater Race and South Rocks. There are only a few by the jetty. The male elephant seal is still lounging on Middle Rock in easy view of Camera 5 on the West Bluff.

Bird Count
26 Canada Geese spent the day sheltering from the storm on Greater Race Rock
670 Adult Gulls + 96 Juvenile Gulls = 766 Gulls total
20 Oyster Catchers
136 Cormorants
I don’t know where the Turnstones and Sparrows hide during bad weather

How I counted Birds: The nice thing about bad weather is that it forces all the birds to come to Greater Race Rock because of the waves surging over the outer islands. They also tend to sit in organized groups when it’s really windy. So I took photos of all the groups of birds and using a ‘cell counter’ macro in a great free program called ImageJ I counted all the birds and tallied the results.

 

[Daily Marine Conservation Link]
Sea stars up and down both coasts of North America are experience a mass die-off event now called Sea Star Wasting Syndrome. In recent years the populations of sea stars has been extremely high in the Salish Sea, and in September 2013 reports of mortality events started coming in from divers. A collaborative research effort is now underway and the Vancouver Aquarium is hoping that divers start to participate in some Citizen Science.
The Howe Sound Research and Conservation team is tracking this event by mapping observations of healthy and sick sea stars  but they need data! So if you see any sea stars while diving report it to this website
