More Sea Lion Injuries Due to Fishing

Weather: 

  • Sky partly cloudy, some periods of fog
  • Visibility 1-15 miles intermittently
  • Wind 20-30 knots W – NW
  • Water rough, whitecaps, swells around 1m

Boats/Visitors: 

  • No visitors today, but on Sunday Corey drove us back to Race Rocks with some more water as we were having troubles getting our boat to start.
  • There have not been many whale watching boats but when they are here they often get quite close to the sea lions (within 10m). We can tell when there is a boat present in the reserve by the increase in “barking” and distressed sounds that the sea lions make.

Ecological: 

  • Over the weekend a sea lion was spotted with some fishing line wrapped around its neck. We believe that it could be the same one spotted last year. As it grows it will likely die due to slow suffocation caused by the line. Unfortunately it’s virtually impossible to have someone come to tranquilize and remove the line as the sea lions move on before they can get here. However, if we see it again we will report the injury.
  • Today we found a large fishing hook which must have come loose off of a sea lion. We’ve previously observed sea lions trying to remove fishing hooks from their skin by rubbing against the jetty.
  • There are quite a few sea lions all over the island now. We have been delaying our water sample that we normally take from the jetty to avoid having to chase them off, since when they are startled they climb over each other or rush off of the side of the jetty where the water isn’t very deep. The few that have come near the house don’t seem to be moving around much, just resting and getting away from the crowds.
  • With the return of the sea lions we’ve been getting bitten by little black fleas that we also saw in late spring. They were not a problem while the sea lions were not here, so we’re wondering if the two are connected.
  • Many of the young seagulls have left or are flying very well. A few of the latest hatched are still here, but the mothers are starting to leave them to fend for themselves.
  • We have been spotting the odd young elephant seal hauling out for a few hours before continuing on.
  • We’ve been noticing eagle feathers and dead adult seagulls around the island. Oddly, we haven’t seen the eagles hunting.

Maintenance: 

  • We’ve been needing to do daily fence repairs on the electric fence at the back of the island as the sea lions have been trampling it and breaking the wire and insulators that hold the wire on the posts. Hopefully with some persistence on our part they will learn to leave it alone.
  • Today we also set up the electric fence that runs between our house and the jetty/north island to prevent them from coming up around the infrastructure. They are stinky and destructive if you let them get too close!
  • We are still picking up sharp bits of tin and shingles/tar paper/ misc. litter from around the island. Some of it is from the roofs being redone recently, but a lot of it is older and becoming exposed now that the grasses are dormant for the summer.  Today we filled two buckets in an hour or two of scavenging.

A Foggy Weekend

Weather: 

  • Sky partly cloudy, some thick fog banks passing over us
  • Visibility 5-15 miles, intermittent fog
  • Wind 0-5 knots W
  • Water calm

Boats/Visitors: 

  • Yesterday we had a great team of volunteers come to help remove the rest of the shingles and accumulated rubbish from around the island. We still have some more to go but it’s looking great!
  • Greg showed us how to set up the electric fencing to keep the sea lions off some of the island. Yesterday we set up one at the back of the island and will need to set up the fence near the jetty soon.
  • Today Corey and his family will pop in for a visit
  •  Our friend is going home this afternoon

Ecological: 

  • We spotted the seagull chick that had been attacked (and lost an eye) yesterday and it’s doing well. It is missing an eye now but is learning to fly alongside the others.
  • We saw two orcas pass just outside of the reserve on Thursday
  • The sea lions have started to come further onto the island, and there are more and more each day

Update on Tagged Elephant Seal Cow

T 562 pink

Recently I sent this email to the folks who are in charge of the tagged elephant seal program in the US .” This year we have had three pups born The tag (on this website) for pups born here over the last few years is https://www.racerocks.ca/tag/pup/ This year the first pup belonging to one of your tagged females, pink tag T562 is doing very well. One other one is ok but the last born one has been mauled by one of the mothers and has died. It would be interesting for us to know when this tagged mother was born so that we know her age and origin

***********************************************************************************************

NOTE : The following link is connected to all the posts on this log relating to tagged elphant seals we have recorded at Race Rocks Ecological Reserve over the past 19 years

https://www.racerocks.ca/tag/tagged/

Today we received this information from Garrett Duncan, Farallon Program Biologist at Point Blue Conservation Science. www.pointblue.org  :

The cow you re-sighted with a Pink tag T562 was born on the SE Farallon Island during the 2010-2011 breeding season and hasn’t been seen since. It’s mother’s name in our database was Peggy and she was likely born in the 1998-1999 breeding season in a colony further to the south, Piedras Blancas. She frequented the island every year between 1999 and 2011.

 

Snow and Coast guard

Weather

  • Visibility: 15 Miles
  • Wind: 5-15 NE
  • Sky: Clear and Sunny
  • Water: A bit choppy, no big waves

Boats/Visitors

  • Guy came by today to deliver fuel and help me with the desalinator, I had some freezing issues with it
  • Coast Guard also dropped by in their helicopter to do some lighthouse maintenance

Maintenance

  • I ran the generator for awhile last night, will do so again tonight
  • tried to run desal but had a freezing issue so will try again when it warms up a bit

Ecological

  • The pup that is alone right now decided the front door was a good place to sleep so I’ve been using the side door
  • the elephants don’t seem too bothered by the snow
  • there are about 3 males around right now, the alpha chases the other two off when they get close

The effects of Vessel Underwater Noise on whales

Currently Mike Fenger and I are representing the Board of the Friends of Ecological Reserves as Intervenors in the New round of Reconsideration Hearings  of the National Energy Board on the Trans Mountain Pipeline Proposal . You can follow this process with its daily updates from participants at https://apps.neb-one.gc.ca/REGDOCS/Item/View/3614457

Since one of the aspects ordered by the Review Panel is the state of the Southern resident Killer whales one of the most disturbing piece of evidence of their plight comes  I have come across is contained in this audio clip:

Pam sees 6-spot the harbour seal

Pam Birley of Leistershire  England has regularly photographed this harbour seal which she named 6-spot , since 2008.. Their lifespan is 25-30 years.

ER Wardens Report, Sept.21

Today, Guy Ouradou from Pearson College drove me out to Race Rocks Ecological reserve with David Obura, Pearson College alumni from Kenya year 10. The main change since I was there last was the predominance of California sea lions over most of the island. Northern sealions occupied a small portion of rock near the docks and the isthmus below the light tower. Each year the college has to put up an electric fence to prevent the sealions from invading the centre of the island which can result in damage to conduits, and facilities.

Laas adjusts the electric fence on the south side of the house.

A new fence system is being installed this year, which has so far proven to be very effective. Another aspect of the sealions being on the centre part of the island is that they have been damaging the structure of the rocks arranged in the areas of the aboriginal burial cairns. The big change in sealion distribution is that previously they have concentrated on West Race Rocks, North Race Rocks and the south Islands off the tower. This year there are none out on those islands  and they are all on the main island.

 

CODAR antenna and sealions

I also was able to observe the equipment installed by Oceans Network Canada for CODAR. Hopefully we can get a connection to the output of the data obtained from this equipment when we neet with Kevin Bartlett from Ocean Networks Canada next week on Sept 28.

Earlier this year, Lester Pearson College upgraded the solar batteries which have served for the past 11 years. New inverters were also installed.

Leaving the island we have to deal with a dock full of sealions which have returned since our arrival.
