Bald Eagles and Sea Lion Bones

Posted on by

The wind blew from the south, switching around to the east and north, by the mid afternoon.  The velocity of the wind hovered between 9 to 15 knots, during the daylight hours.  The barometer dropped from 1027 hPa to 1018 hPa.  The sky was overcast, with rain in the afternoon.  The temperature was 8oC for most of the day, dropping from 10oC yesterday.

There were no boats seen in the reserve today.

This morning, nine bald eagles were in reserve at one time:  four adults and five juvenile. They made at least one kill of a gull, just below the high point of the island, northwest of camera 5.

During a beachcombing exploration this afternoon, I found a partially decomposed sea lion carcass.  It appeared to be a steller sea lion, based on the appearance of the fur and flippers.  It was near where I had found other sea lion bones a few weeks ago.  The bones had been mostly cleaned by gulls and insects.  It looked fairly recent, because the fur was still intact and attached to several parts of the skeleton.

Eagles, waves and engine troubles

The barometer continued to rise today, from 1019 hPa to 1024 hPa.  The wind blew from the west and southwest between 14 and 34 knots.  The sky was mostly clear, with occasional brief showers and rainbows.  There was a large swell coming in from the west.

There were no boats seen in the reserve today.

There were four bald eagles seen in the reserve this morning.  Large groups of gulls got to practice their evasive manoeuvres as the eagles flew overhead.  Our UK camera viewer, Pam Birley, spotted a peregrine falcon on the helicopter pad at 15:20.

I was unsuccessful in running the monthly check on the fire pump and refill of the salt water cistern, but not for lack of trying.  I strung all the hoses from the jetty to the underground cistern, only to find that neither engine was willing to start and pump.  I will continue to tinker with those engines.  On the up side, I got to practice unrolling and rolling all the hoses.

Black Brant Goose

Last night the anemometer was reading wind gusts of up to 53 knots from the southwest. That’s 100 km/h!  As far as I can tell, nothing blew away overnight.  There was a fresh load of driftwood delivered to the beaches.  Today, the wind continued to blow from the southwest and west.  The wind had low velocity in the morning, rising to the high twenties in the afternoon, and dropping to 11 in the evening.  The barometer continued to rise from 990 hPa last night to a high of 1018 hPa tonight.  The sky cleared up in the morning, with sun all day.

Four whale watching boats were seen in the reserve this afternoon.

This morning, I saw a black brant goose hanging out with the gulls on the northeast corner of Race Rocks.  It was my first time seeing one of these small geese, which rarely visit Race Rocks.  This goose might be making it’s way down to the Oregon, California or Mexican coast for winter, from it’s summer home in the Arctic.  For more information about black brant geese, see the taxonomy page.

Surf and Surf Scoters

The wind blew at 10 knots from the north for the morning.  In the afternoon, the wind increased to 25 knots as the direction swung around to the southwest.  The barometer dropped from 1011 hPa to 990 hPa as the sun set at 16:28.  The sea was rippled, then a big swell rolled in from the southeast during the afternoon.  A gale warning is in effect with winds possibly topping out at 47 knots.  The sky was mostly overcast with some breaks of sun and occasional rain showers.  The rain water cistern is filling itself up again after the dry spell.

There were no boats seen in the reserve today.

A single surf scoter, Melanitta perspicillata was spotted in the reserve this morning, before it took off towards the west.  The waves crashing into rocky shore produced some spectacular splashes.  Sea lions were surfing the waves and leaping out the top.  The low light and rain made photography difficult.

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.

 

Overcast with Calm Seas

Posted on by

The barometer continued to drop slowly from 1023 to 1018 hPa.  The wind continued to blow between 8 and 18 knots from the northeast.  There was a difference in the weather today, compared to the clear sunny skies that have been the usual for the past week.  Low clouds hung over the Juan de Fuca Strait for most of the day.  There were occasional breaks of sun in the late morning and early afternoon.  The whitecaps this morning calmed right down in the afternoon, making the sea the calmest it’s been for the past few weeks.

There was one recreational boat seen this morning in the southern part of the reserve.

Pam Birley, from the UK, sent two photos of sea lions that she captured on Camera 1, located at the top of the lighthouse.  Pam’s photos show two branded sea lions that have never been spotted at Race Rocks, as far as I can tell.  See the photos below.  Thanks Pam!

The desalinator was run today to top up the fresh water cistern.  The solar panels aren’t soaking up as much energy, due to the clouds.  The generator was run longer today to help out the energy intensive desalinator.

The Barometer Begins to Dip

The wind blew between 8 and 18 knots from the northeast throughout the day, less strong in the afternoon.  The day began with occasional whitecaps and a small swell from the northeast, calming down in the late morning. The barometer dropped from 1030 to 1023 hPa, ushering away the high pressure system that has been around for the past week.

There were no boats seen in the reserve today.

At 13:00, a group of humpback whales were surfacing about one kilometre to the northeast of the reserve, with no whale watching boats in sight.

The usual daily tasks were performed: salinity test, running the generator, collecting wood, cleaning the solar panels and general maintenance.

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.

More Wind, Waves and Clear Skies

Posted on by

The wind blew between 23 to 37 knots from the east for most of the day.  A swell with 1m waves continued from the east.  The barometer dropped from 1027 to 1019 hPa.  The visibility was unlimited, with clear skies.

There weren’t any boats seen in the reserve today.

Only one elephant seal was seen today by the jetty, where upwards of 16 have been spotted there in the last few weeks.

I received some information from Pat Gearin at NOAA about three of the branded steller sea lions seen within the past several days.  All three were branded as pups in Rogue Reef, Oregon.  I have reposted the photos below.


833R was branded in July 2009 as a pup when he weighed 32kg and was 110cm long.  Since then he has been seen in June 2011 at Patrick’s Point, CA; and June 2014 in Tatoosh West, WA.
946R was branded in July 2011 as a pup when she weighed 29.9kg and was 108cm long.  Since then she has been seen in December 2011 at Pachena, BC; June through September 2012 in Rogue Reef, OR; and in July 2013 at Jagged Island, WA.
872R was branded in July 2011 as a pup when she weighed 30.8kg and was 107cm long.  Since then she has been seen 16 times between Pachena, BC and Tatoosh West, WA.

The desalinator ran today for 8.5 hours, creating about 600L of fresh water.  The solar panels were producing 1.2kw of electricity this afternoon.  The windows on the Ecoguardian’s house were cleaned inside and out.  More cleaning and installation was done in the basements of the two houses to ready the spaces for the composting drums and collection units for the new composting toilets.
