Break in Foggy Weather: Census + Pelican!

Posted on by

Weather: 

  • Sky partly cloudy, some sun and blue sky
  • Visibility 10-12 NM
  • Wind 20-15 knots W
  • Sea state: fast moving currents, still fairly flat despite wind

The fog horn continued for 20+ hrs each day until today. For most of this week we have had less than 100m visibility, making it impossible to see even a boat passing through race passage or the end of the jetty. At some points, we could barely see the guest house from the main residence! It can be difficult to focus and/or work productively during these long periods of fog, as the fog horn sounds three long high-pitched “beeps” every 45 seconds. More info on the history of Race Rocks foghorns Here!

Visitors: 

  • There have not been any visitors to race rocks since Monday when Greg and a contractor stopped in briefly.
  • There have been 1-2 tour boats in the reserve daily, but we can often hear them before we see them in the fog. The sea lions are easily startled by them because of the limited visibility, and sometimes when the boats emerge from the fog the sea lions run into the water.

Ecological Observations: 

  • The sea lions have officially taken over the island! We have been dutifully repairing the electric fences daily to keep them from damaging the buildings and especially from disrupting the burial cairns.
  • There have been an incredible amount of interesting birds to observe this week, despite the weather. Today we saw a pelican while enjoying the sunshine right from our back porch! This is a new sighting for us at Race Rocks and we were quite ecstatic.
  • On the note of bird sightings, we are hopeful for the installation of a new bird tracking device on Race Rocks sometime soon which will allow us to view migratory birds passing through the reserve as it detects their tracking bands.
  • One of our favorite elephant seals, E103 or “Erica” has returned again. We were happy to see her looking healthy yesterday- she had been hiding behind the piles of sea lions, and we only saw her once we had shooed them to install more electric fencing.
  • Identifying gulls is incredibly difficult. Some of them look the same aside from a slight wing color difference or color of feet determining them as a separate species! We are wondering if the gulls we have been assuming to be non-breeding california gulls are actually thayer’s gulls. Back to the id books!

Census:

  • 96 Stellar sea lions
  • 383 California sea lions
  • 88 Harbour seals
  • 1 Elephant seal
  • 1 Sea otter
  • 52 Brandt’s cormorants
  • 1 Brown Pelican
  • 1 Oregon junco
  • 2 Fox sparrows
  • 15 Savannah sparrows
  • 1 Yellow-rumped warbler
  • 1 Short billed dowitcher
  • 14 Black turnstones
  • 8 Canada geese
  • 320 Glaucous winged gulls
  • 113 California gulls
  • 20 Heerman’s gulls

Census and a Beautiful Day

Posted on by

Weather: 

  • Visibility 0-10 NM (some intermittent morning/evening fog)
  • Sky clear
  • wind 25-30 knots W
  • Sea state: rippled, whitecaps
  • A steep decline in humidity today helped dry out the island after a bit of rainfall

Neat Fact: The body temperature of seals is very similar to our own! Endothermic like us, they maintain an internal temperature of 36.5-37.5 degrees Celsius.

Marine Traffic/Visitors: 

  • Greg visited today to top up island supplies before the college vessel goes for regular maintenance
  • Not many boats today- around 5 eco-tourism vessels.

Ecological Observations:

  • Elephant seal V173 was not here today. We wonder if she was just stopping for a rest or if she will be back soon.
  • There have been very large groups gulls and also black turnstones migrating through, intermingled with a few surfbirds. There were so many today that we took a photo from the lighthouse in order to count them!
  • The pigeon guillemots seem to be nesting in full force. We have spotted many carrying fish into crevices on the west side of the island near camera five and also the rock walls on the east side.
  • The seagull takeover has seemingly started to ease and moving around the island is becoming easier day by day. The chicks are beginning to be able to escape the attacks of the rival adult gulls by flapping their wings and flying/hopping away.
  • On a slightly…mushier note (stop reading if you get queasy!): Yesterday we removed the gull that was eviscerated on our back porch. We let it sit for a few days to see if an otter would come back for it or if the gulls might take a nibble (neither occurred). We were surprised by the amount of maggots that had grown in only a couple of days, presumably due to the warm and humid weather recently.
  • The sea lion population is increasing every day and they are started to climb onto the main rock. It’s almost time to put up the electric fence or we will have unwelcome house guests!
  • The geese have suddenly left this week (all but 4). Interestingly, earlier in the week we saw a flock of 17.

Census: 

  • 4 Canada geese
  • 985 Seagulls (does not include chicks)
  • 84 Harbour seals
  • 1 Male elephant seal
  • 25 Stellar sea lions
  • 19 California sea lions
  • 88 Pigeon guillemots
  • 2 Bald eagles
  • 1 Humpback whale (in the straight)
  • 1 Brandt’s cormorant
  • 12 Black oystercatchers
  • 143 Black Turnstones
  • 1 Sandpiper ((?) will update with confirmed id!)

 

 

 

A New Arrival

Posted on by

Today’s Weather Conditions: 

  • Sky overcast
  • Visibility 15+ NM
  • Wind 15-20 knots W
  • Sea state: calm, fast moving currents today (almost 5 knots)
  • Daily fog in the mornings and often late afternoon as well

Marine Traffic/Island Visitors:

  • No island visitors aside from Greg on Thursday with supplies
  • Quite a few whale watching boats today and yesterday (20+)
  • Not many pleasure crafts passing through the reserve, but many outside of pedder bay (especially yesterday)
  • We saw 3 whale watching boats just outside the reserve circle a small group of orcas and follow them under power into the strong currents earlier this afternoon.

Ecological Observations: 

  • Today we were joined again by elephant seal V173. She was also here in December and again in the late spring when we first arrived. Her left eye is a bit oozy and red, but it seems like it is still functioning properly and she is otherwise looking great! She must have eaten a lot of fish out there- she’s much bigger than the last time we saw her only a few months ago.
  • The seagull chicks have been wandering farther away from the safety of their nesting areas, and we have been seeing quite a few more deceased chicks on the ground all around the island. They are being killed by rival gulls protecting their territory and young. There are a few chicks with injuries from these attacks, such as broken legs or wings.
  • We found an eviscerated gull chick on our back step on Friday afternoon. It looks quite a bit like a chicken does when a mink kills them (head missing), so we wonder if this is the work of a river otter.
  • As mentioned above we observed a few orcas just outside of the reserve earlier today. We have also been seeing humpbacks passing quite far away in the straight.
  • The pigeon guillemot nest that we have been observing closely (near our back porch) has at least one chick! We carefully peeked into the crevice and caught a glimpse of a tiny puff of black downy feathers. We are excited to be able to watch their activity so closely from our window as they are very secretive with their movements typically.
  • The remaining male elephant seal has been venturing to other parts of the island as his moult is finishing up. He has been finding some creative places to wiggle over rocks into shallow pools heated by water spilling over sun warmed rocks as the tides rise.
  • We heard a surfbird’s call today while out near the jetty- it’s a very shrill sound, just like the second recording here.

Beautiful Spring Day

Posted on by

Weather: 

  • Sky partly cloudy
  • Visibility 15+ NM
  • Wind 10-15 knots SW
  • Sea state: calm, rippled

Visitors/Marine Traffic: One pleasure craft within the reserve yesterday

Ecological: 

  • There are now 5 goslings between 2 nests
  • There are 2 oyster catcher chicks (nest on E side of island). They are too elusive for our camera for now!
  • The garbage brought to the island by seagulls is increasing now that they are nesting and laying eggs
  • Yesterday we spotted a patch of broken seagull eggshells near the guest house. Our best guess: the gulls are already looting neighboring nests for food

 

Spring Showers Brought New Critters!

Posted on by

Weather: 

  • Sky overcast
  • Visibility 10 NM
  • Wind 10-15 knots W
  • Sea state: calm

Boats/Visitors: 

  • One pleasure craft fishing within the reserve today. They did not have a visible number so we were unable to report to DFO.
  • Yesterday Greg brought water which we pumped into our storage tank

Ecological: 

  • Today a large male elephant seal arrived! He is huge!
  • The smaller female elephant seal has returned for a bit more R&R
  • There are now goslings! There was one nest behind the boat shed which we did not see before. This morning we noticed two little fluffy goslings peeking out. Adorable!
  • The oyster catchers have begun to lay eggs
  • The seagulls are also laying eggs in full force. The nests are becoming fully established all over the island. They have become more defensive of their areas, which means we need to cover up! One of their favorite defense tactics is flying above us and trying to hit us with their droppings.

Ixoreus naevius; Varied Thrush- The Race Rocks Taxonomy

Posted on by

 

Ecoguardian at Race Rocks,  Nick Townley , spotted this first specimen recorded occurance of Ixoreus naevius  a  Varied Thrush at Race Rocks on February 22 2020

At this time of year the migranting birds are starting to show up. Their flyway is from the Olympic Penninsula , 10 Km across the Strait of Juan de Fuca , and the Race Rocks archipelago is the first landfall that they can rest on.   This record is the 20th migrating songbird species that has been photographed at Race Rocks over the past 20 years. . About another 20 species of migrating seabirds also use Race Rocks as a migratory stopover in the spring and fall .

Setophaga townsendi: Townsend’s warbler- The Race Rocks taxonomy

Posted on by

Our first observation  of this species at Race Rocks was made by Laas Parnell, Ecological Reserve Warden on Dec 16, 2019.

Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Passeriformes
Family: Parulidae
Genus: Setophaga
Species: S. townsendi
Common name Townsend’s warbler

 

and this reference  from The Cornell Lab website:

Backyard Tips

On the Pacific coast in winter, Townsend’s Warblers often investigate backyard feeders, most regularly when temperatures drop below freezing, to eat energy-rich foods such as mealworms, peanut butter, and suet.

  • Cool Facts
    • On the wintering ground in Mexico, the Townsend’s Warbler feeds extensively on the sugary excretions (known as “honeydew”) of scale insects. It’s such a good food resource that Townsend’s Warblers set up and defend territories around trees infested with the insects.
    • Townsend’s Warbler was first noted to science by John Kirk Townsend, an American naturalist who collected a male specimen near the mouth of the Columbia River in what is now Oregon, on April 16, 1835. His discovery followed a long cross-continental trek. Townsend was accompanied on this expedition by English botanist Thomas Nuttall. Dozens of western plants and animals bear the names of these early naturalists.

Larus californicus: California Gull

Posted on by

In March 2010 Pam Birley captured this gull with the remote camera. She wrote “I saw a California gull recently and attach pics.  You don’t seem to have any in the taxonomy pages.   It’s not a rare gull but this maybe the first I have seen at RR.” Indeed it is one of those gulls which has fallen through the cracks so this is a rather late addition to our taxonomy.

This adult plumage is reached after 4 years. Note the black tip on the bill and the yellow legs which distinguish it from the Western Gull.

Larus hyperboreus: Glaucous Gull — The Race Rocks Taxonomy

Posted on by

A photo of the rare second year Glaucous Gull on the right, Western Gull on the left. Photo March 8, 2009 by RyanThis is only the third record for this area in the Rocky Point Bird Observatory records.

Probable identification of the white gull on the left is the immature Glaucous gull. The gull on the right is an immature Glaucous-winged gull (photo 21st Dec 2005..camera 5 by Pam Birley)

To the left: This is a tentative identification. If it is correct, according to David Allinson of the Rocky Point Bird Observatory, ” this probably represents only the second record for Glaucous Gull (a 1st winter bird) for Rocky Point’s checklist (and a first for Race Rocks too!). The big head, the large bubble-gum pink dark-tipped bill, and white head and body (at least what can be seen) seems to be diagnostic.
However, to be cautious I should only say probable as we cannot see all of the bird.”

It nests on the tundra, and the range is circumpolar.It moves South in winter but only small numbers reach as far as the Pacific Northwest.”

Plectrophenax nivalis: Snow Bunting –The Race Rocks Taxonomy

Posted on by

Laas Parnell took these pictures of Snow Buntings on November 9, 2017. Pam Birley had been the only one to take pictures of them previously in 2005 and 2007 on the remote cameras at Race Rocks.

This is a very pale Snow Bunting . Snow Buntings are uncommon around Victoria and best seen in late fall-early winter, so any bunting in February is unusual. This is only the fourth Snow Bunting record for the Rocky Point Bird Observatory checklist. The last picture is a poor image through a blurry remote camera 5 housing,but the only one we have so far of a male snow bunting which was taken by Pam in March 2007.
