Oyster Catcher Nest Sites

Posted on by

Ecological Notes:

  • 7 Elephant seals between the grass and the boat ramp. It appears another female may have left the reserve. Still 2 “pups” here. (included in the 7 total)
  • The pups are definitely using up their baby fat, and showing lots of wrinkles. The male is still molting though.

    When he finishes molting, he can head off to feed.

  • Have now verified 4 Black Oyster Catcher nests (able to view the nest from good vantage points in the distance). Quite confident in at least 2 more from the bird behavior, but no good distant vantage point to confirm, and don’t want to disturb the birds.

Visitors:

  • EagleWing Tours provided  Pearson College Students with 1 hour tour of the reserve and surrounding area (water based only). Total of 34 Students.
  • Between student tours, 2 employees of EagleWing Tours were brought to the main island by the waterfront coordinator for a visit.
  • The Waterfront Coordinator also delivered groceries, drinking water and electric fence supplies

 Facility Work:

  • Repairs and alterations to the electric fence on the main pier. This is important not only for the safety of the facility and the heritage sites, but also for the safety of the Sealions themselves. If they come up the top of the pier and are startled from their sleep (by land, or boats in the water), they run the risk of jumping over the side from a high height, into shallow water. Generally, on a natural rock face, steeper slopes continue into deeper water.

Noted Vessel Traffic:

  •  2 Ecotourism vessels, 1 commercial Dive Tour operator. All with proper viewing and usage procedures.

Good behavior in the reserve! (some compression from the distance and my lens, NOT as close to the rock as it may appear!

  • 3 Private vessels, all with good approach and viewing.

 Noted Infractions:

  • The most common error, generally speaking, is that private vessels tend to power up too early on departure from the reserve.

Again, some compression effect from my lens, but this private boat had come up to speed even earlier than this, well within the reserve.

Weather Events:

  • Mostly clear with westerly winds at 15 knots most of the day. Westerly winds increased to 25 – 30 knots in the evening, bringing in some haze and clouds.

Census

Posted on by

Although the Census is normally posted without additional comments, there is an extreme variation in this one. Even after a 1 day delay, there are dramatically less animals in the reserve today. An anecdotal possibility is that Sunday night had a 50+ knot storm, lining up with a high tide and lots of big ocean swells, making the reserve a very nasty place to be! Tuesday morning also had many large DND detonations that also scattered wildlife as it was returning.

Birds

  • Bald eagle adult 1
  • Bald eagle juvenile 2
  • Gulls, Glaucous and Western 58
  • Cormorants 3
  • Pigeon Guillemots 22
  • Oyster catcher 10
  • Canadian goose 8
  • Canadian goose, goslings 2

Mammals

  • Steller sea lion 3
  • Harbour seal 53
  • California sea lion 13
  • Elephant seal juvenile male 1
  • Elephant seal female 5
  • Elephant seal pup 2 – 1 male, 1 female
  • Sea otter 1
  • Animal Tracking and Injuries: 0

Cleaning and Maintenance

Posted on by

Ecological Notes:

  • 7 Elephant Seals, including 2 “pups” still using the grass areas
  • Monday saw a dramatic reduction of animals and birds in the reserve (almost no guillemots or Sealions, and about half the number of gulls) but they are gradually returning.
  • An anecdotal possibility is that Sunday night had a 50+ knot storm, lining up with a high tide and lots of big ocean swells, making the reserve a very nasty place to be!
  • Noticing more Black Oyster Catcher nests. These are more just an indentation in the gravel, and the birds rely a lot on the camouflage of the eggs. Due to high egg loss rates (here, primarily gulls snatching them), Oyster catchers can lay up to 3 or 4 replacement clutches in a season.

Very distant photo

Visitors:

  • Guests left Sunday
  • 4 Pearson College students on Monday, for an informal visit, with some discussions on marine mammal adaptations life in the ocean.
  • Was also nice to re-instate the visitor log in the newly painted and repaired Visitor Welcome Box

Facility Work:

  • Trouble shooting power interruptions originating from the Student Building
  • Cleaning and minor repair to the housing on the Camera 5 unit.
  • There’s an old prairie saying “Make hay while the sun shines” …… out here, the addendum could be “Clean stuff while the rain falls!” Rain makes it much easier to clean paths and windows, and through the rain collection, provides water for the pressure cleaner.

DND events:

  • 6 or 7 loud blasts today, all sealions left the rocks again

 

Weather Events:

  • Westerly winds, 15-20 knots brought rain showers in the morning. Mostly sunny with cloudy periods in the afternoon. Calm seas. Clear skies and 20 knot westerly winds in the evening

Student Exams

Posted on by

Ecological Notes:

  • 7 Elephant Seals between the grass area and in the water by the ramp throughout the day.
  • Second, (and possibly third) Black Oyster Catcher nest located

Visitors:

  • 2 boats brought 20 Students and 1 Instructor to do part of the Marine Biology Exam today. Lots of activity in the various areas of the inter-tidal zones

    Rock Landing

    Orientation

  • Garry Fletcher and associate spending the night working on a media project.
  • Shorefront Coordinator brought groceries and new printer

Noted Vessel Traffic:

  • 2 EcoTour Boats demonstrating correct behavior at all times
  • Several private vessels, also viewing wildlife. Some had slightly close initial approach, but all observed backing off at the slightest notice from the wildlife

    Respectful Viewing (some compression effect from my lens, they ARE at an appropriate distance)

 Noted Infractions:

  • Unfortunately, most private vessels came up to speed too soon while in the reserve during departure, (some even still in between the various rocks on the north side) but no animal disturbance noticed …. still, there were collision risks and wake though.
  • Photos taken after I noticed the behaviors. Behaviors started well before the photos

Weather Events:

  • 10 – 15 knot westerly winds all day, sunny with fog patches, quite dense at times. Winds increasing to 25 knots in the evening, still westerly

Sea Otter Viewing

Posted on by

Ecological Notes:

  • 7 Elephant Seals on the grass, including 2 “pups” from this season
  • Spotting from the rear deck of the house, I noted the single Sea Otter in the Kelp bed off the East end of the island . Took a quick picture from the deck, and then headed to the north shore, to follow along the rock edge to get a better vantage point …… took the long way around to avoid the Oyster Catcher nest posted yesterday

From the back deck 600mm

From the shoreline

  • Did you know? California Sea Lions get gray fur on the top of their head, as well as their chin when they grow old? Eventually, their backs too!

Old Gentleman

Enjoying the sun

 

Facility Work:

  • Window cleaning, wood stacking, setting up science building for guests

Weather Events:

  • Westerly winds all day at 10 – 15 knots, fog in morning and evening, sunny during the day

Oyster Catcher nest

Posted on by

Ecological Notes:

  • 7 Elephant seal on the grass, including 2 pups. 4 have moved the furthest away from the ramp as I have seen them (towards the southern side of the island, but still up in the grass)

By the solar building

  • Knowing the extra importance of staying off the rocky/gravel areas this time of year, I did my normal perimeter check from the grass, and solid rock areas. I noticed a Black Oyster Catcher doing more of a distraction behavior rather then their normal “go away” squeals.
  • I immediately left the area and searched from a distance with the spotting scope. It took a while, but sure enough I found the nest!!!! (my first ever sighting)
  • Although always true, I CAN’T STRESS THIS ENOUGH – photos shot from as far away as possible, with a 600mm equivalent, then cropped to show better detail! (please read the captions)

Facility Work:

  • More waste wood stacking ……. Due to the obvious fire ban in the reserve, and to the unknown paint content, all waste wood has to be removed from the island and processed properly. Making it easier and safer for the recovery team just makes sense.

DND events:

  • 6 detonations during the day

Noted Vessel Traffic:

  • none (DND vessels kept area clear)

Weather Events:

  • Westerly winds during the day at 10 – 15 knots, increasing to 25 knots early evening.
  • Fog in the morning, followed by mainly clear skies, then fog returning in the evening. Low fog throughout the day to the west and south.

All day distant fog

Evening fog, can’t see the mid channel rocks

Juan de Fuca CODAR System – Race Rocks (VROC) – Oceanographic Radar System

Posted on by

CODAR antenna at Race Rocks

Click on this image for the data display on the Ocean Networks Canada website:

CODAR SeaSonde continuous surface current mapping and wave monitoring HF radar system.

This is taken from this page: http://vocab.nerc.ac.uk/collection/L22/current/TOOL1366/

http://vocab.nerc.ac.uk/collection/L22/current/TOOL1366/
SeaVoX Device Catalogue
Preferred Label CODAR SeaSonde continuous surface current mapping and wave monitoring HF radar system
Definition A high-frequency radar system designed for fixed deployment on the shore or on offshore structures. It measures continuous sea-surface current velocities and wavefield conditions such as significant wave height, dominant on-shore direction and dominant wave period. The CODAR SeaSonde transmits radio waves, receives Doppler-shifted reflected signals and processes the resulting data into radial ocean current velocities. The data from two or more radial stations can be combined into total velocities, i.e. ocean currents resolved into their N-S and E-W components. Total velocities are available only in regions of overlap with other stations. For wave measurements, the SeaSonde works on the principal of Bragg scattering; radial stations detect radar backscatter from ocean waves with wavelengths one-half the radar wavelength. The radar system is available in three configurations: Standard, Hi-Res and Long-Range. The SeaSonde’s spatial range varies from 15 – 220 km (dependent on the configuration), and offers 360 degrees coverage. The angular resolution is a 1-5 degree grid and is user selectable. Significant wave height accuracy is 7-15 percent, dominant on-shore direction accuracy is 5-12 degrees, wave period accuracy is 0.6 s, current accuracy is typically <7 percent of the total current velocity.

Pearson College Students

Posted on by

Ecological Notes:

  • 4 female Elephant Seals, 1 Juvenile male, and 2 “pups” in the main grass area.
  • Behavior change in the male pup over the last couple days …… When by himself, he is still very docile, but when lying close with the female pup, he takes on a very defensive attitude, even when viewed from quite a distance.

Like most photos, taken from a distance and then cropped!

Visitors:

  • The waterfront coordinator brought a student landing party, then returned later to deliver distilled water for the batteries, parcels for the ecoguardian, and more students
  •  Pearson College: 14 students and one instructor, toured the reserve by water and visited briefly for a talk on the burial sites, the elephant seals, sea lions, and take in the view from the top of the lighthouse.

Greg discussing important cultural significance of areas on the main island with students.

Discussing the “ballast” cannon recovered from the Swordfish wreck site with students.

 Weather Events:

  • Low westerly winds during the day, bringing fog in the morning, giving way to sunny skies and 15 knot westerly winds during the day. Westerly wind increasing to 25 knots after dark, bringing the fog back in by about 2100hrs.

Wildlife Returns

Posted on by

Ecological Notes:

  • The Elephant Seal that left the grassy area 2 days ago, is now in the little bay at the east side of the main island. Spending a lot of time diving. Really tough to spot!

That’s her, the little grey spot left of center! Photo taken from the top of the tower!

  • The other seven Elephant Seals (including the 2 “pups”) still mostly lounging in the sun, but most took at least one dip in the water by the pier.

  • Greater White-fronted Goose returned, and spending time with the Canada Geese.

 

Facility Work:

  • More Painting, minor parts repairs

 

Noted Vessel Traffic:

  • 2 Private boats, stayed centered in the channel, sealions took note, but not overly disturbed

Weather Events:

  • Light westerly winds, building over the day to 25 – 30 knots by evening. Threatened fog in the morning from the west, but burnt off by the time it got close. Cloudy with sunny breaks throughout the day.
