January 17th Census

Posted on by

Looking South from to the Lighthouse towards the Elwha.

Weather: Overcast morning, with a sunny afternoon. Winds 15-25knots. Big storm on January 11th that blew our doors and windows open.

Visitors/Traffic: After a week of no visitors we got 4 boats today: a whale whatching boat, 2 small fishing boats and a yellow sailboat that was very interested in getting in close to the jetty.

Ecological Notes: Immediately after the last birth a new female showed up on the island (January 11th). Cheermeister’s mom left him on January 12th (21 days of nursing) after making with the Beachmaster 76 times over 3 days. I didn’t inspect every event, so the total could higher than that, but it was an impressive feat. The Beachmaster has shown no interest in any of the other females. There are still 2 large males on the island, with the Beachmaster (previously referred to as Bernard) staying with the females and the other male hanging out around our compost.

The new seal gave birth last night, bringing our total seal pups to 4!

Jocelyn gave birth to her pup last night with lots of shouting and fanfare.

Elephant Seal flippers look so ridiculous when they’re born, just oversized and floppy. Kinda like puppy paws.

Tons of eagles on the island this morning, which usually coincides with a reduction in other birds counted.

Cheermeister: fat and alone. I don’t understand how he still gets fatter after being weaned.

The Beachmaster checking if anyone is interested in mating yet.

Census:

Gulls: 136

Cormorants: 360

Eagles: 40

Turnstones: 13

Elephant Seals: 9 [2 bulls, 3 females, 4 pups]

Steller Sea Lions: 142

California Sea Lions: 155

Harbour Seals: 6

 

Peace descends over the nursery. Seriously though, Elephant Seals are soooo loud.

Bonham over drumming next to the compost where the Beachmaster can’t find him.

January 10th Census

Posted on by

Weather: Overcast, but mostly sunny over the last few days. winds 15-20knots.

This feels like we got more sun in January 2021 all of 2020.

Visitors/Traffic: Pretty quiet week, a few fishing boats driving by.

Ecological Notes: Newest Elephant Seal pup was born today. This makes 3 pups total, with the oldest nearing the end of his nursing period. His mom is looking VERY depleted, with 3 more days estimated until the end of her nursing period. His mom has also had a large behavioural change: previously she would ‘fight’ with the Beachmaster when we attempted mating, but over the last 24 hours she’s now much more receptive to his advances. 13-14 times a day receptive.

Cheermeister at 19 days. Looking fat and healthy as his mom gets more and more depleted. In 2020 we saw the pups nurse for 23 days, so he’s getting close to the end of ‘free food’.

Census:

Gulls: 259

Cormorants: 719

Eagles: 6

Turnstones: 22

Elephant Seals: 8 [2 bulls, 3 females, 3 pups]

Steller Sea Lions: 160

California Sea Lions: 121

Harbour Seals: 10

Proof that I take photos of other animals than Elephant Seals. SE Steller Rookery going strong.

Mothers seem to have lots of aggression shortly after a pup is born. Every pup we’ve seen get born here coincides with a bought of mom-on-mom aggression. Although Courtney has pointed out that this is my interpretation of their behaviour, and this could just be a ‘welcome to the fraternity of motherhood’ moment.

Mating looks rough. In larger rookeries this often results in pups getting squished. Here, Cheermeister just needs to avoid getting pinned and he should be good. He’s repetitively gotten in the middle of that mating between his mom and the Beachmaster and hasn’t died…. yet.

Peace descends. As with all things Elephant Seal: the chaos doesn’t last long. After 30 min of excitement everyone rolls over and falls asleep until tomorrows moment of activity,

 

Elephant Seal Pup Growth – Day by day

Posted on by

The first Elephant Seal pup of the 2021 birthing season came on December 22 2020, and began it’s 23 days of nursing the day after (it took him awhile to figure out how to nurse). Elephant seal pups only have a couple of weeks to get big enough and healthy enough to survive alone after their moms wean them and abandon them on Race Rocks; which means their life is essentially just to feed, nap, and snuggle with their moms. It’s hard to show how impressive it is to see how fast they put on weight, with the pup doubling in size over the first few days. Here’s a video of the growth of ‘Cheermeister’ over his first 12 days of life.

Christmas Bird Count at Race Rocks 2020

Posted on by

Today was the annual Christmas bird count. Martin Stewart provided the transportation on the boat Ecosphere for Matt and Courtney Cameron to go out to Race Rocks Ecological reserve from Pedder Bay with Garry Fletcher. 

Observations were done from the marine a out through Pedder bay and then we docked at Race Rocks to be met by Courtney the Ecoguardian.  We had only a brief window of time, probably an hour  there before the wind started to pick up from the North East, but that was adequate to get a good count of the birds on shore.

Pam Birley from England took these photos on camera 5 :

Striking in their abundance were the and Pelagic and Brandts Cormorants. On leaving we circled around the South side of the islands and out past West Rock where there were also large numbers of cormorants.  From West Race Rocks we went over to Emdyck Pass behind Bentinck Island and found another large gathering of Cormorants, and some alcids.  The other bird that seemed much more frequent than previous years were the Black Turnstones

On the island, after stepping carefully past a male elephant seal on the jetty, we were able to view the new pup and mother elephant seal with the large male up on the lawn by the house. 

The following three sets of data are from their e-bird posts,

Baby Elephant Seal for the Holidays

Image

Newborn Elephant Seal pup! After a night of squawking we were met in the morning by this adorable squishy new baby. It makes the cutest sounds!

Weather: 2 days of over 30 knots. Sleet on the afternoon of December 21st after a morning of NW bringing lots of logs into the jetty.

Visitors: 4 tourism boats coming out to view wildlife. Coast Guard doing maneuvers in the crazy currents. Navy ship and submarine out for a jaunt.

 

Maintenance: Greg got the desalinator going. We got Ocean Network Canada’s equipment up and running, I’m told it measures the tides and currents using radar?! Pretty cool. Maybe the subject of a blog post already?

Wildlife: The Elephant Seals showed up in the first week of December, so we were expecting a few months of them hanging out on Race Rocks before anything significant happened. Just kidding! The lone female on the island (pink tag #2) gave birth at around 10pm on December 21st after a chilly afternoon with a bit of snow.

Baby Elephant Seal #1. Could be last years pup? They are thought to return to their same birthing/moulting grounds.

The big male that has been posted up with the female since the beginning of December seems to be pretty protective of the new baby, making sure the rowdy teen male seal knows he is not welcome around the female and pup. There is another large male hanging out next to the generator building, and a small male (possibly last years pup) was hanging out here for a few weeks before heading back into the ocean.

The big male chased the female around the island for a few days before she found her favourite spot and posted up. Turns out those rocks right in from of her is the best nursery.

Momma Seal: Pink tag #2

Having a well deserved rest with her newborn the the giant male stands guard for other males.

We’ve still got lots of California and Steller Sea Lions hanging out on the island/jetty, with lots of bait balls and kelp rafts drifting by. There’s been at least 2 humpbacks feeding between Race Rocks and Edye Point for a few days.

 

Only 1 gull has died in the last week, and was pretty quickly eaten by a couple of eagles.

Because every Race Rocks blog should feature a lighthouse photo.

 

December 18 2020 Wildlife (Census)

Posted on by

Visitors/Traffic: A few whale watching boats and small fishing vessels came out to look at the sea lions.

Ecological Notes: One new observation of a gull acting weird before dying and being eaten by eagles. Currently there are 4 elephant seals on Race Rocks: One dominant male, one submissive male, one juvenile male, and one pregnant female. Looks like this female showed up a little earlier than last year, which may be an attempt to birth and nurse in peace before other mothers show up.

Census:

Gulls: 318

Cormorants (mostly Brant’s): 816

Eagles: 3

Elephant Seals: 4

Steller Sea Lions: 330

California Sea Lions: 144

Turnstones: 11

 

 

A Diver and Dying Seagulls

Posted on by

Weather:

  • Visibility 10-20 NM, great visibility especially in the few hours before sunset
  • Sky partially overcast
  • Wind 5-15 knots W
  • Calm seas for the most part, other than strong ebbs and floods

Visitors: Some pleasure craft over the past days. There have been some supply deliveries as well as a few visitors for various reasons. Today we saw what looked to be a private vessel enter the reserve and put a diver in the water. The dive lasted less than ten minutes and when the diver was back in the boat, they left quickly.

Ecological Notes: 

  • The elephant seals are all here still – the two large and two small ones from earlier in the week. The two larger seals and one of the smaller ones have hauled themselves up high onto the island, and the other smaller seal looks to be more comfortable closer to the water. Look for them on the webcam!
  • We’ve had a few more strange seagull deaths with the same symptoms: gradual weakening (reluctance to fly and a lethargic walk), separation from the rest of the seagulls, eventually progressing to being unable to fly, and finally silent coughing/choking movements followed by death.
  • Two orcas spotted on Monday, behind north rock and heading east.
  • There’s still a heavy sea lions presence, mainly on the jetty and the surrounding rocks, and around the base of the lighthouse.
  • Mid week we had around 20 eagles in the area and were able to catch a few quick pictures of them in flight!

 

Clear Skies + Elephant Seals! (census)

Posted on by

Weather:

  • Visibility 15+ NM
  • Sky mostly clear, overcast in late afternoon
  • Wind 0-10 knots N
  • Sea state: calm, glassy!

Visitors: A small number of pleasure crafts trickling through. Only a handful of tourism vessels over the weekend and a few through the late week.

Ecological Notes: 

  • This week has brought some of our favorite visitors to Race Rocks: elephant seals! We’ve been joined by two huge male elephants seals as well as two younger pups that look to be only a year or so old. Unfortunately we haven’t seen any tagged elephant seals yet so that’s all we know for now.
  • We’ve still been spotted seagulls displaying odd behavior. We’ve noticed a total of 7 over the past month.
  • Whale sightings have slowed down now, seemingly as the weather gets colder and salmon runs slow. We have still been seeing around one per day but the sightings are less consistent.
  • Today we noticed a tiny sea lion pup nursing! We mostly only see male sea lions on race rocks, but recently we’ve been noticing very small sea lions arriving. It’s hard to tell the sex of sea lions from a distance so this was the first female we’ve identified in the crowd.
  • The bald eagles have continued to visit to fish and hunt gulls in the early to late morning. They particularly like to sit under the tower containing camera 5, sometimes up to 10 at once! The color variation throughout their different life stages is particularly striking.

Census:

  • 54 Harbour seals
  • 177 Stellar sea lions
  • 233 California sea lions
  • 4 Elephant seals
  • 275 Brandt’s + pelagic cormorants (too far away to distinguish)
  • 6 Double-crested cormorants
  • 5 Surfbirds
  • 3 Dunlins
  • 25 Black turnstones
  • 12 Harlequin ducks
  • 7 Bald eagles
  • 290 Thayer’s gulls

Measurement Exercise

Posted on by

Today we had a request from Meghan Byrne, a 6th grade science teacher in the San Francisco Unified School District. She was doing a lesson with her students on size and scale and she was interested in using the following picture from this blog of the elephant seal measuring device – and letting students determine its length.

 

 

 

So I thought that would be a good exercise to include here for school students. Ecoguardian Mara has provided the following photos of the boat ramp rail so you can now calculate the length of the small elephant seal. 

Be sure to calculate the length of the Elephant seal in both centimeters and in inches.  Then you can also convert it to Metres and Feet . 

Mara sent another picture of a larger male, the brackets on the rail can just be made out so calculate his size.

 

Busy Shorebirds, Sea Lion Shot?

Posted on by

Weather:

  • Visibility 15+ NM
  • Sky partly cloudy, blue sky and sun!
  • Wind 0-15 Knots NW
  • Water calm

Visitors:

  • A few supply drops to the island otherwise quiet, not much traffic
  • Some navy vessels on the water today as some blasting was taking place on the DND land.

Ecological Notes:

  • Today we spotted a young seagull displaying the same symptoms as the one we found a few weeks ago: extending its neck as if to catch its breath or perhaps dislodge something stuck inside its throat. We noticed it initially because it had separated from the group and had tucked under some foliage. Within 15-20 minutes it appeared to be unable to move aside from lifting its head, and with wings splayed it died. We did inspect inside the mouth and throat that we could see and nothing appeared to be lodged inside. We are not sure what caused these deaths (or if it was the same cause), but we are interested to learn more. We are hoping that we will be able to send it for a necropsy.
  • On Saturday we were surprised by a large male elephant seal! He was so huge that he dwarfed even the largest sea lions here in the reserve. Wow! He must have had places to be and moved along the next day.
  • Our whale sightings have slowed down now, although we have been still spotting at least 1 humpback whale every day. They seem to appear around peak ebb current to feed around the reserve.
  • We have been periodically checking on our dead sea lion that appeared last week. Although not officially determined, after some input we strongly believe that the animal was shot. It appears as if it was shot and then made it onto land here before passing. While it is a heartbreaking find, we are excited to observe the decomposition process.
  • We have been observing gulls pecking at the remains of gulls killed by eagles. The cannibalism is not necessarily a surprise to us, having also observed adult gulls eating the chicks of other gulls over the nesting seasons. However, it is interesting, given how much food is readily available.
