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

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.

 

Pup is doing well

Weather

  • Visibility: 15 Miles
  • Wind: 10-25 SW
  • Sky: Cloudy
  • Water: A bit choppy out there today, waves didn’t look more than a metre high

Boats/Visitors

  • A few ecotours going by today, as well as a couple dive boats

Maintenance

  • Ran the generator for a bit longer today, was going to run the desalinator to top off the water tank but was having some problems with it, will try again tomorrow

Ecological

  • The pup belonging to pink tag T562 is doing very well, I took a closer look at it today and suspect its female but still not completely sure
  • Still just the one pup, sometimes it takes a few days for the females to give birth after they’ve hauled out
  • The alpha male is very friendly, gentle and protective with the pup so that’s great news, it’s keeping the beta males away

First pup of the year

Weather

  • Visibility: 15 Miles
  • Wind: 10-25 NW
  • Sky: Mostly Sunny, some clouds
  • Water: A bit choppy out there today, waves didn’t look more than a metre high

Boats/Visitors

  • A few ecotours going by today, not many other vessels around

Maintenance

  • Just getting used to being more energy efficient and also using the woodstove more rather than the furnace

Ecological

  • The tagged female that showed up the had a pup at around 16:45 today, too early to tell the gender but I will get better photos tomorrow. I expect one more pup to be born soon, as the other large female on the island is looking quite large.
  • The tag on this female is pink and the numbers have rubbed off
  • The big guy who I think is chunk (need to get a closer look at the scars on his back) seems to be reacting well. He hasn’t shown aggression so far towards the pup.

T 562 pink tag, pregnant

Weather: Overcast, light wind. Showers in the afternoon.

Ecological:

-Around noon a large, pregnant looking female elephant seal hauled up the boat ramp and onto the island.  She is the first pregnant female to show up on the main island this season and is possibly the first flipper tagged pregnant female to come here.  She has a pink flipper tag (T562) which indicates that she was born at Point Reyes or the Farallones Islands near San Francisco. One of the male elephant seals took immediate interest and rushed over to her, there was some physical contact, some biting (him) and lots of wailing and wriggling (her). She did not seem interested at first but eventually they were lying side by side and seemed calm.  The larger male seemed only semi-interested and let them be.

-The Polar Adventurer, a crude oil tanker, passed by on its way from Anacortes to Valdez.  It is in the photos below with a male elephant seal in the foreground. The Alaskan Legend, also crude oil tanker,  passed by on its way from Valdez to Cherry Point.

Vessels: 2 tour boats

Maintenance:

-cut wood

-work on month end report, records and write up

-send in December sea water sample data

 

 

C887

Weather: good visibility, wind North 10 knots, sky overcast, 2 foot swell

Vessels: not much boat traffic in the area today.

Ecological:

-Tankers: Kouros (oil/chemical) passed by on its way to Manzanillo Mexico and The Alaskan Navigator heading to Port Angeles

-We continue to have 4 male elephant seals and 3 females, including C887 (green tag) on the main island (observed previously). C887 was quite interested in a puddle, she would put her snout in the water and make bubbles then appeared to swallow mud from the bottom and cough it back up.

Maintenance:

-continued work on energy system assessment, took battery bank specific gravity and voltage measurements of each cell.

-transfer 80L diesel to engine room, fill generator tank

-cleared driftwood from boat ramp

 

Last post until the new year

I am heading out tomorrow for winter break but both Jeff and Alex will be here.

Thought I would do one last count before I head out for a couple weeks, there seemed to be more Steller Sea Lions around today

Weather

  • Visibility: 15 Miles
  • Wind: From 0 – 15 NW but its supposed to blow pretty hard tomorrow
  • Sky: Overcast
  • Water: Pretty calm, can see some decently sized rollers out there

Boats/Visitors

  • A few ecotours going by today, it was relatively calm out

Maintenance

  • Getting the house ready for the next person, trying to fill up the fresh water tank as much as I can before I go as well

Ecological

  • Decided to do another count, seems to be the same amount of Californias but a few more stellers out there today
  • Another large male elephant seal showed up, the scars on his back resemble chunk which makes wonder if the one that has been here the past couple days is Bernard or Boss, will need more photos to compare
  • There are currently 3 female elephant seals, one of them is tagged, C887
  • a few surf scoters out there today
  • Noticed a neck banded sea lion on the jetty today, will let the next person know to keep an eye on him, if he sticks around maybe we can get some help for him

Census

  • California Sea Lions – 216
  • Steller Sea Lions – 265

Bye-bye Race Rocks

This is my last post as Ecoguardian for summer 2018 – I’m headed back later this afternoon and Laas will be returning to take over.

Weather

  • Visibility: 10 miles
  • Wind: 15-25 knts W
  • Sky: slightly hazy/partly cloudy
  • Water: Calm
  • Strong winds last night cleared part of the haze, and we have blue skies after a long period of grey.

Boats/Visitors/Sightings

  • Guy arrived yesterday to take away all the garbage and recycling from the island, so there would be less to take back today.
  • The increasing number of sea lions on the jetty have caused more and more boats to approach close to the dock – just a reminder that DFO guidelines set a 100m minimum for observing distance!
  • On Tuesday, a group of Pearson students from the SPELL group came for a short tour on the island.

Island maintenance

  • I raised a new Canadian flag yesterday after the old one was beginning to wear out.
  • The Ecoguardian house has been completely cleaned for the next Ecoguardian
  • Guy and I washed some of the pathways outside the science shed

Bird notes

  • The first of the juvenile seagulls have now taken full flight – they soar as high as the adults now and even fly above the ocean.
  • Saw one adult seagull with an injured leg and a juvenile with an injured leg as well. Not sure if this is just a coincidence or an attack tactic by other adult seagulls, but it immobilizes the injured bird almost completely.

Marine mammals

  • A tagged female elephant seal has arrived at the island. The tag number is C887. Apart from a few scratches on the back, the seal is in very good health.
  • The harbour seal pups seem to have grown quite a bit, gaining some weight and coming close to adult size
  • The sea lions have started settling around the helipad and the back of the guest house (near the tidal radar) – an electric fence will be needed soon to allow for movement space.

Seagulls lay eggs

Weather

  • Visibility: 15 Miles
  • Wind: 15-20 NW
  • Sky: Partly cloudy
  • Water: Ripply/Calm

Boats/Visitors

  • Few ecotour boats scattered through the day

Ecological

  • Spotted a young elephant seal (about 3-4 ft in length) near the jetty.
  • Seagulls have laid their eggs! I estimate about 30-40 eggs on the island so far, definitely growing in number. Some seagulls are still building their nest/adding more straw
  • Spotted a tagged elephant seal near the jetty. Tag number was B198. Photo below
