Windy Windy Spring Weather

Posted on by

Weather:

  • Visibility 8-10 NM
  • Sky overcast
  • Wind 35-40 knots W
  • Sea state: large swells and chop, breaking at 1m

Visitors/Marine Traffic:

  • No marine traffic today as it has been very windy
  • Greg and a technician came on Wednesday
  • Garry and a visitor came yesterday evening

Ecological: 

  • there is one elephant seal now. She spends most of her time near the fuel shed, or on the jetty near “Boris” the sea lion (with the propeller injury on his head).
  • The seagulls have been fighting quite a bit now that their population is becoming denser and space is limited. The male seagulls fight more often, and their female mates are usually nearby observing.

Returning Sun, Census

Posted on by

Weather: 

  • Visibility 15-20 NM
  • Sky partly cloudy clearing to blue sky
  • Wind 15-20 Knots W
  • Sea state: calm, rippled

Visitors/Marine Traffic:

  • No visitors
  • Yesterday we spotted a group of kayakers who had emailed to let us know they were coming: We tried to wave, but you were too far away to see us- hope you had a good paddle!

Ecological: 

  • The seagull population has skyrocketed this week, but still no fully constructed nests
  • The elephant seals have left now, aside from one. We anticipate that we may see a few large males in a month or so.

Census: 

  • 16 Geese
  • 8 Oystercatchers
  • 39 Sea Lions
  • 40 Harbor Seals
  • 1 Elephant Seal
  • 1 Bald Eagle
  • 580 Seagulls
  • 42 Pigeon Guillemots

Stunning Weather, Spring at Full Force!

Posted on by

Weather:

  • Visibility 15+ NM
  • Sky clear
  • Wind 5-10 knots SW
  • Sea State: calm

Marine Traffic/Visitors:

  • 2 jet skis yesterday evening, 1 kayak this morning, 1 eco-tourism vessel yesterday
  • Greg today with supplies (thanks Greg!)
  • 1 boat inside the reserve fishing this morning- Greg stopped to remind them that they were within the boundary on his way
  • Many pleasure crafts just outside of the reserve boundary

Ecological: 

  • Consistent eagle presence as the seagulls continue to return, and food is plentiful in the water
  • The geese seem to be getting pushed out of their territory by the seagulls. The seagulls have continued to steal goose eggs when they get an opportunity, thus there are only 2 remaining nests with eggs. The geese have started to spend more time on the water, and often leave during the day.
  • The pineapple weed has been growing at an impressive rate! Most of the grassier areas on the island are covered by the fluffy foliage.

 

Eagle Visit, Watching For Injured Sea Lions

Posted on by

Weather:

  • Visibility 10 NM
  • Sky overcast
  • Wind 5-10 knots SW
  • Sea state: calm
  • Temperature 21°C

Visitors/Marine Traffic:

  • Today Laura visited to do some surveying of intertidal species
  • Greg did not come to land, as the tide was very low (jetty not accessible)
  • Today we saw one whale watching vessel pass through very respectfully with the current. No animals were disrupted- well done!

Ecological:

  • The goose nests continue to change- a few new ones this week, and a few have been ransacked by seagulls.
  • No significant seagull changes- a few new nests scattered around the island.
  • This morning a juvenile eagle landed on the lawn! It had been chased out of the air by seagulls, and they continued to swoop overhead until the eagle managed to find an opening and fly away.
  • We have been contacted by a few different folks regarding a sea lion that was spotted in the San Juan Island area with a cross bow bolt in his face. We haven’t spotted this animal but there’s a chance that we may over the next few days. We have also been asked to keep an eye out for another sea lion with fishing gear entangled in his face.

Notes:

  • This afternoon there was blasting/ammunition detonation on the Department of National Defense land. There were only 3 blasts but the birds all lifted into the air, or in the case of the sea lions, fled into the water.

Blooming Biodiversity

Posted on by

Weather:

  • Visibility 15+ NM
  • Sky clear
  • Wind 15-20 NE diminishing to 5-10 SE
  • Sea state: calm
  • Temperature 22.5°C

Visitors/Marine Traffic: 

  • A trickle of pleasure crafts outside of the reserve, 4 inside of the reserve
  • Yesterday a very small vessel came to the reserve with 3 people aboard. They approached each outcropping very closely, scaring the animals into the water.
  • This evening a boat with 6 passengers sped through the reserve. They passed the resting sea lions very closely, and sped through the passage where many were swimming and fishing.
  • On Friday Greg visited to work on the generator, and Nick came too
  • There have been large commercial barges steadily passing through the straight. Since the weather has been so calm we can hear them inside the house, even though they are nearly 8 km away.

Ecological:

  • The elephant seals have been taking daily soaks in the shallow water surrounding the jetty in this warm weather.
  • In the shallow and warm waters this week we have been spotting schools of small fish. The larger animals in the water seem to ignore them completely.
  • There have been blooms of jellyfish passing by in the currents, mostly water jellies and the small “sea gooseberries” which seem to glitter in the light due to the the tiny hairs (cilia) that pulsate to move them through the water.
  • A few harlequin ducks spent the evening in the reserve on Friday

Census: 

  • 16 Canada Geese
  • 8 Oyster Catchers
  • 4 Crows
  • 8 Elephant Seals
  • 300 Seagulls
  • 2 Cormorants
  • 2 Bald Eagles
  • 48 Sea Lions
  • 9 Harbour Seals

Coralline Algae Discoveries, Impossible Invasive Plants

Posted on by

Weather:

  • Visibility 15+ NM
  • Sky clear
  • Wind 5-10 knots SE
  • Sea state: calm

Visitors/Marine Traffic: 

  • One medium sized catamaran passed through race passage this morning drifting on the current
  • This afternoon we were joined by Guy and Christine, who brought us some generator hardware and spent a bit of time enjoying the beautiful weather.
  • Quite a bit of commercial traffic outside the reserve today including barges of logs and shipping containers.

Ecological: 

  • There are quite a few beginnings of seagull nests now. They have become more aggressive, and now fight each other over space. We have seen some pairs mating.
  • We have been finding coral-like white fragments in the intertidal since last year, but until now have not been able to identify what they could be. Today we found some that were not white, but red! This insight has led us to believe that this is coralline algae. Amazingly, this article states that these unassuming structures can continue to grow forever (!) if left undisturbed and have growth rings that be counted, just like trees!
  • As Gary Fletcher mentions in this post, prostrate knot weed is one of the invasive species here on Race Rocks. We noticed that it is particularly efficient at growing in places where no other plants are able, therefore it’s beginning to spread in rocky areas. It has notably spread to the rocky areas on the SW side of the island where no other flora nor fauna has managed to establish itself.

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 .

Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Passeriformes
Family: Turdidae
Genus: Ixoreus
Bonaparte, 1854
Species:I. naevius

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

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.
