Weather: 

  • Visibility: 15+ miles
  • Sky: overcast
  • Wind: 15-20 kn NW
  • Water: Little choppy under 1 foot

Visitors/Boats: 

  • Since I got back on Tuesday there have been approximately 15 boats per day, the number varies a bit each day
  • On tuesday and thursday we had visitors from the eagle wing crew come for a tour on Race Rocks. It was so nice for them to be able to come check out what Race Rocks looks like from the land after seeing it from the water so many times
  • Greg and Guy are coming by today so we can do a more in depth orientation on the projects and maintenance going on around the island

Ecological

  • After my walk around I noticed a couple interesting things, first there was a young steller, not a baby but he was still nursing.
  • Then an elephant seal, which was so nice to see and it had a green tag on it. Unfortunately by the time I got my camera it was already gone.
  • There have also been humpbacks nearby lately, the past two days there have been 4. Yesterday when the eagle wing crew was here was saw a fishing boat getting way to close to the whales, the whales were clearly upset and one jumped right out of the water because of it. Luckily we saw one of the whale watching boats from BC tours and got a hold of them and they let us know they had a word with the fishing boat about keeping its distance from the animals.

Maintenance

  • The fence still needs to be repaired twice a day but the sea lions are starting to stay away from the entrance to the generator room with regular clearing which will also start happening around the burial cairns between the student house and the helicopter pad. The sea lions have started shifting the stones around a lot and we want to preserve this important historic area.

Seal Studies and Helicopters

Posted on by

We received a response from the scientists who had tagged the elephant seal mentioned and pictured in this previous post. They were able to share some interesting information about GE103, whom we nicknamed Eric. GE103 was part of a mother and pup interaction study, as well as the subject of a blubber biopsy study.

 

“Eric”, GE103

Juliette Linossier, a researcher working under a Fyssen grant at UC Santa Cruz/Año Nuevo Reserve, was able to tell us more about the early life of this animal and others. She told us that shortly after the birth of another elephant seal (GE338), there was a huge storm at Año Nuevo and GE338 was separated from it’s mother. The pup was stuck on the beach, and his mother in an protected elevated area. They called to each other for a long while, but were never able to return to each other. GE338 did survive but was nursed by another female in the colony.

The now ’empty nest’ mother of GE338 became attached to GE103! She nursed him, and stayed close to him and his mother, G9474. Thus, GE103 (or as we call him, Eric) was able to take advantage of more than one milk source as a pup; the two mothers even fought over him from time to time.

According to her bio, Juliette wants to investigate the link between allonursing and maternal cognitive abilities using new approaches. Using time-lapse photography, chemical profiles and other techniques she plans to look at variables such as maternal age, pup similarity, genetic connection, spacial proximity and more to further understand what drives allonursing in these interesting creatures. Thanks for sharing, Juliette!

GE103’s blubber biopsies were taken for the purpose of furthering the understanding of pollutants bioaccumulating in marine mammals. Read more about this subject here.

Many thanks to Patrick Robinson, director of Año Nuevo Reserve and lecturer at UC Santa Cruz, for helping us learn more about this work.

We left Race Rocks last Monday (October 30th), and hours before leaving we were surprised by the landing of a Bell 412EPI Coast Guard helicopter. They came to Race Rocks in order to replace the solar battery bank beside the foghorn (near the base of the lighthouse). We were able to get great video of them landing as well as taking off!

Unfortunately, as one can see at the left of the video the landing scared many sea lions off of the rock in a rush. Without knowing that they were coming we had no chance to gently move any vulnerable animals away from the helicopter pad. We were able to speak with someone at the college about this, and the Coast Guard will hopefully be able to better work with Race Rocks in the future to ensure the safety and comfort of the animals.

The pilot was kind enough to take a moment to show us around and allow us to take some pictures. He explained that a smaller helicopter could have been landed near the house, but the 412EPI’s cargo capacity (over 6000lbs) was needed to transport the batteries. The helicopter is powered by a Pratt & Whitney PT6T-9 turboshaft engine that makes over 2000hp (about 1500kW), and it’s made in Canada!

We enjoyed our time at Race Rocks (a big thanks to everyone who supported us during our term), and hope to return and continue this work protecting and observing the fragile ecosystems and the animals within. Until next time!

Cameras are back up

Boats/Visitors

  • Had a few visitors this morning

Maintenance

  • as many of you noticed the cameras were down, that is because there was an issue without the router on Saturday, we just got replacement parts today and everything should be up running this also includes my internet which means I can post on this blog again

Ecological

  • A lot of elephant seals lately, there are 7 females and 4 males, this includes the pup
  • The males are very small, no big noses yet, they must be 2 or 3 years old, one of them has a green tag D018
  • the female pup left two days ago but the male pup is still here, he will probably leave any day now
  • only one of the females has been molting so far, the other 6 will probably start soon
  • I have counted 6 goose nests so far, I haven’t been able to addle them because I do need someone to help me fend off the geese while one takes the eggs. We do this is a population control method and have a permit to addle goose eggs

  • had a couple of visitors today, come by for a little tour

Ecological

  • Turns out the elephant seal we have been identifying as female since it first turned up in December 2017 is actually a male. It is tagged, a green tag C887
  • I noticed he went through a major growth spurt since spotting him in December 2018 which is common in male elephant seals but not really in females, he is hanging out with the tagged elephant seal that had the pup here in January
  • the pups are doing great, swimming in the mornings when the adults are out of the water, they don’t interact much with the mature elephant seals

Molting

Boats/Visitors

  • a few boats out today
  • had someone out here to look at the desal, hopefully solving that issue soon

Maintenance

  • we’ve been getting a lot of solar but today is cloudy so I’ll run the generator and desal for a few hours

Ecological

  • the pups are having fun splashing around
  • there are 3 females altogether, one of them is quite young probably 2 or 3 years old the other two are much older and they will be molting soon, we should be expecting more females within the next couple weeks
  • no more male elephant seals around just the pup
  • not  a lot of sea lions but there are plenty of harbour seals on the outer rocks
  • I have not spotted any goose nests yet but I’m sure it’ll happen soon, not looking forward to that, looks to be at least 8 nesting pairs on island

  • Ran the desal for a while yesterday, I’ve just been trying to keep the tank topped up

Ecological

  • two females showed up today, one of them is the tagged mother of the female pup and a new one showed up as well about the same size.
  • the pups are getting more adventurous, the female pup was swimming this morning but the male pup is still just sticking his face in

Beautiful weather

  • There has been so much solar, I don’t need to run the generator very much, so thats been really nice

Ecological

  • There was a pretty young sea lion pup on the rock by the crane today
  • the pups have not gone in the water today but they are wandering around quite a bit, so they will probably be splashing around soon, I think the female pup might have put her flipper in for a moment but I’m not sure
  • One of the mothers came back very briefly, the tagged female, pink tag T562, who gave birth to the female pup on Jan 4th was here for maybe a couple hours then she went back into the water

Update on Tagged Elephant Seal Cow

Posted on by

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.

 

Pup is doing well

  • 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

  • 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.
