Long term record for harbour seal at Race Rocks

Pam Birley sent this picture today that she took with the remote camera of Six-spot, a harbour seal she has photographed over a several year period. see previous post at http://www.racerocks.ca/6-spot-the-harbour-seal-observed-at-rr-since-2008/

Sea Lion Rescue

Weather

  • Visibility: 15 Miles throughout the day
  • Wind:  0-5 SW throughout the day
  • Sky: clear this morning, clouds rolled in around 3
  • Water: calm

Boats/Visitors

  • Fisheries along with a vet and people from the aquarium came by to help a sea lion who had a piece of rope or something like it wrapped around its neck

Ecological

  • plenty of sea lions around

Notes

  • DnD was blasting again today
  • It was nice to have those people come around to help the sea lion out, they first sedated it via dart gun and once it was safe to approach they removed the garbage that was wrapped around the sea lions neck and monitored it until woke up and swam away

I am Back and the Census

Sorry about my last 10 days being absent but I am back now and here is an updated census.

Weather

  • Visibility: Pretty clear 15 Miles throughout today
  • Wind:  0-5 SW with small range all day
  • Sky: Sunny all day
  • Water: pretty flat but the current is very visible and moving

Boats/Visitors

  • I came in today and so did a few students to have a look around, we also had an engineer to come look at the new generator

Ecological

  • quite a bit of sea lions, I don’t see the elephant seal sticking around anymore and I have not seen any oyster catchers today. Also the sea otter in the north kelp patch is back

Census

  • Stellar Sea Lions: 142
  • California Sea Lions: 186
  • Elephant Seals: 0
  • Harbour Seals: 28
  • Unspecified Gulls: 153
  • Pigeon Guillemots: 0
  • Cormorants: 18
  • Canada Geese: 12
  • Oystercatchers: 0
  • Black Turnstones: 48

 

Sun and Fog

Weather

  • Visibility: 0 Miles this morning, the fog horn was going off for a good portion of the morning but I am getting a very clear and beautiful sunset now
  • Wind:  10-15 SW which went up and down slightly throughout the day but around 10ish knots
  • Sky: thick fog for a bit and then it cleared right up in the afternoon
  • Water: pretty flat

Boats/Visitors

  • Quite a few ecotours came by today

Ecological

  • The unspecified birds are still around and I have determined them to be black turnstones, however it is weird to see such a high number of them at once so it is possible there are some other species of surfbird mixed in there too

Notes

  • Had some power issues today, hopefully get everything fixed tomorrow and the dryer won’t die on me halfway through drying my laundry

Lazy Day

Weather

  • Visibility: 15 Miles
  • Wind:  10-15 SW
  • Sky: overcast some rain
  • Water: pretty flat throughout the day

Boats/Visitors

  • A few ecotours came by today

Ecological

  • Definitely more sea lions everyday plus that one female elephant seal that is sticking around

Notes

  • Puttered around today, almost have a full water tank again, and enjoyed taking photos of the frequently napping sea lions
  • Now that there is more cloud cover the solar panels aren’t bringing in a lot of energy so I do need to run the generator to run the desalinator

Translator Added

I have added a translator to some of the website pages. If there are other languages that you wish to add, let us know and we will edit the script for the dropdown box below:

Christmas Bird Count-1

We had lined up several people to go out today for the annual Christmas Bird Count, unfortunately the gale warning and the increasing wind from the North East made it impossible to get anyone out . With an impending storm the birds often disappear and such seems to be the case today. The following general pictures showing the few groupings of birds were taken from the tower camera 1  at mid-day. Alex will provide on the ground details later.

Beautiful Day to Remember

 

End of Shift.  Tomorrow Riley will arrive for his shift and we will be off. All the best, Riley, for your stay in this amazing hotspot of living activity and tidal rushes. The people of BC are lucky to have Race Rocks protected under BC Parks’ highest level of protection as an Ecological Reserve. It was a pleasure working with the classes of biology and marine science students this week and a treat to be in this special place.

Weather and Sea Conditions  Winds: Light and variable;  Sky: Morning low overcast slight mist cleared to sunny in afternoon;  Visibility: Mostly good ~10 – 15 nm;  The accumulated solar radiation today was 250 Langleys, the equivalent of a little over 2900 Watts per square meter. The UV Index was high at 7.4;  Barometer: 102.7 kPa and falling Sunday evening;  Forecast: Wind easterly 5 to 15 knots becoming light Monday afternoon then increasing to west 20 to 25 Monday evening. Strong wind warning in effect.

Vessels in Ecological Reserve   Whale watching vessels: 12 were observed working in Ecological Reserve (ER). All were professional, providing a good model for other boaters transiting the ER.

Sport fishing vessels: A total of 11 sport fishing vessels were observed in the ER today. Three were noted speeding in the ER and two vessels were observed fishing for hours, in the closed to fishing, Rockfish Conservation Area. Photos were taken, processed and filed. There were approximately 70 sports fishing vessels fishing to the west and then drifting by to the east, all but five appeared to follow rules.

Ecology  The first three Harlequin Ducks of the season were spotted today, one male and two females. They have returned from their alpine summer breeding habitat for a coastal winter. A Great Blue Heron was observed fishing, standing on a dense raft of Bull Kelp. A thorough search for the Sea Otter turned up nothing. Enormous mixed species feeding flocks were observed in Race Passage in the afternoon. There are fewer sea lions ashore during the day right now and there have been dietary shifts visible in their feces, which are hard to miss. One animal was observed feeding on what appeared to be a Coho close to a kelp bed on the west side of Great Race.

Visitors  None.

Sustainability  Although it was gray in the morning by 14:00 there was enough sunlight that we made fresh water with solar energy powering the de-salinator.

Maintenance and Operations  Regular chores and clean-up.

 

Weather’s Fine

Weather and Sea Conditions

Winds: 5 – 15 knots, west-southwest

No other commercial operators, noted in Reserve today.

Sport fishing vessels: Five noted in Reserve today. None observed fishing in ER. One sport boat speeding through ER. One open run-about with a windshield was seen chasing a Humpback Whale and hopscotching with it in order to position itself in front of whale’s path.

Scorpaenichthyes marmoratus: Cabezon–The Race Rocks Taxonomy

Scorpaenichthyes marmoratus

cabezonCabezon are normally benthic or bottom-dwellers, living among rocks and seaweeds in tide pools. Sometimes they live just below the water’s surface among the marine plants. Their coloration allows them to remain well camouflaged. Their habitat is most likely rocky, sandy and muddy bottoms, living in areas with a depth range of 0 to 200 meters. Moreover, young cabezon feed on small crustaceans like amphipods, shrimp, and crabs. The adults feed on crustaceans, marine worms and mollusks, including clams and abalone. They can swallow a whole abalone and later regurgitate the indigestible shell; therefore, their tropic level is that of a secondary carnivore. In addition, the limiting factors that will affect the development and growth of this population in a certain habitat will be the presence of enough light, temperature and the availability of food and living space.

Domain Eukarya
Kingdom Animalia
Phylum Chordata
Sub-phylum Vertebrata
Class Actinopterygii
Order Scorpaeniformes
Family Cottidae
Genus Scorpaenichthyes
Species marmoratus
Common Name: Cabezon, Scorpion Fish

The cabezon ( literally big head in Spanish ) is a benthic fish that lives among the kelp holdfasts and rocky areas, usually very close to the bottom. It is often so confident of its camouflage that it will not move when approached by divers. Note the multi colored eye. These fish will lunge at almost anything that moves on the bottom. Dissections of their stomachs reveal amphipods and small crabs, pieces of kelp (and even rocks they have grabbed when foraging for other invertebrates.)

Their maximum length and weight are 99.0 centimeters and 14.0 Kilograms respectively. This organism can be seen in the Eastern Pacific, which covers the areas from Southeastern Alaska to Punta Abrejos, in Central Baja California, Mexico. Race Rocks is located in the centre of this range. In this map we can see the range of this fish.
