Census July 6

Posted on by

Ecological Notes:

  • I am seeing more gull chicks everyday. Many gull parents are frequently feeding their two or three chicks.
  • I seem to have come to an understanding with some gulls. If I approach near them on the path at a slow speed, we both ignore each other. There are other gulls who freak out if I even look in their direction. As I do necessary work, I limit my movements around the island and avoid certain paths that have nearby nests and chicks.
  • See photo gallery and captions for more details on the ecological happenings over the past two days.

Gull Chicks Everywhere

Posted on by

It is great to be back as the Ecoguardian at Race Rocks. I have been lucky enough to spend a total of almost seven months here between 2014 and my last shift which ended on September 1, 2020. I have been spending the past three and a bit days reacquainting myself with the island and infastructure. I have not stayed here before in July, so it is taking some adjustment to live in harmony and not disturb hundreds of nesting gulls. It drastically limits where I can go on the island.

Ecological Notes:

  • The glaucous-winged gull population is increasing everyday with lots of chicks hatching. I do my best to avoid getting close to the nests. I move quickly by the ones near doors and pathways on which I need to travel to get to the energy building, jetty and lighthouse.
  • A pod of orcas swam westward through the ecological reserve on Saturday, July 2, then went eastward in Race Channel. The orcas continued to head eastward, with at one point 14 ecotour boats viewing them from a safe distance.
  • A juvenile male elephant seal, tagged D018/D019, has been hanging around here for a while this spring and early summer. I noticed the tags this weekend, so I could confirm it was the same seal that Ecoguardian Joan spotted on the seal’s arrival on the island on May 19. Here is a link to the tagged resight histories, when I spotted this seal in April 2020 and reported the details to the Director of the Año Nuevo Reserve, in California. The brief version is he was tagged in February 2017 as a pup in Año Nuevo. He was first observed at Race Rocks in April 2018. He was again spotted here in April 2019, December 2019, and April 2020. His proboscis (nose) and body has grown a lot in the past couple years. I wonder what adventures he has gone on in that time.
  • I know of two black oystercatcher chicks that I have seen through the binoculars and  long lens of the camera. One is hanging out near the jetty with its parents. The other is hanging out near east bay with its parents. The dark grey fluff ball chicks are hard to spot, as they blend in well with rocks.
  • See the photos below for these and more ecological sights.

Weather:

  • The wind has been consistently coming from the west over the past four days that I have been here.
  • Friday and Saturday were part cloudly with lots of sun to fully charge the solar panels by 17:00 both days.
  • Sunday and Monday were overcast with periods of rain and fog.
  • The temperature in the past four days has ranged between 11 to 14 oC.

Visitors:

  • Greg drove the boat on the afternoon of Friday, July 1 to do the shift changeover between Jillian and I. Thanks, Jillian, for leaving the place in such great shape.

Vessel Traffic:

  • Many Canadian and American ecotour boats have been nearby throughout this long weekend.

A Quick Return

Posted on by

After finishing my term at Race Rocks on April 19, there was an unexpected schedule change and I was asked to return on April 30. It took a little quick re-arranging, but I was able to help  out!

Always a relaxing view

 

Ecological Notes:

  • 5 Elephant Seals on land, 4 in the process of molting.
  • This year’s only surviving pup is still around with occasional 1 or 2 day ventures out and back

  • Although the adult  Canada Geese are still around, there is only one pair still sitting on a nest. No other chicks around.
  • There are a few sealions returning to the ramp area, but none are hauling out on the actual rocks they normally do … and they all seem very nervous. Just speculation(!), but they all left the main island rock the day the Orca hunted one just of the island.

Visitors:

  • One of the previous Ecoguardian’s friend came out for a quick visit when we were doing the exchange.

Facility Work:

  • More path cleaning, fence repairs and general maintenance.

Noted Vessel Traffic:

  • Gradual increase in the volume of Eco-Tourism vessels coming to the reserve, depending on wind direction.
  • A few  kayaks and even some sailboats making their way around the island.

 Feature Event:

  •  When I was here last time, I designed and prototyped some simple electric fence connectors. The ideas was for something fast and simple to use when the weather was bad, or to quickly secure the fence, followed by the ability to return later and re-enforce it with a wired secure.
  • The ones installed 3 months ago were all in place, so I have made some more. They are made with plant-based resin, and most likely, they will always be replaced before they fail completely.
  • Also making some gifts for co-workers, and teaching props while I have a printer here with me.

Weather Events:

  • The full range of late spring weather and temperatures. Wind days up to 50 knots,a and some shorts and t-shirt days mixed in.

Don’t trust the weather report

Morning visitors

Weather: SUN! westerly wind 16 knots. Sparkling water.

Visitors: Several whale watching boats. All came close to the seal lions on the jetty but they didn’t disturb them. Fishers outside reserve area.

Work: cleaned solar panels. chopped wood. cleaned windows (on the inside) in lamp room.

 

Energy: Every morning it is a bit of guess work to see  if I can hold off using the generator. Particularly today when it called for clouds and rain. I was happy the first hour of potential solar energy boosted the batteries to over 50 volts. Then I had some breathing room. I tend to look at the numbers often and try to see how I can avoid the generator or use it as little as possible. Not listening to the forecast can be useful!

Observations: Gulls are beautiful. They are so easy to take for granted but now that I am looking closely at them I see how exquisitely white they are. It is amazing to get to watch them go through their courtship. I don’t envy the few immature gulls on the island. If they try to land anywhere near the centre of the island they are quickly reminded that this is a breeding colony and they are not welcome.

Several sea lions have taken to lying on the steps of the jetty. The new electric fence keeps them from coming right up. I feel somewhat sad about this, thinking that for years they have returned and sandwiched themselves on that cement surface. We had to move them off every day to take water samples so it wasn’t an absolutely ideal life. I just wonder how often they need to get zapped to stay away and if there is anywhere nearly as comfortable.

It fascinates me that I can’t get near the nesting Canada geese. I make big detours to avoid the nest and therefore avoid getting attacked and yet the several hundred pound mammals prove no obstacle. They will readily move when I need to take a water sample.

The 6 female elephant seals have split into 2 groups (by size it seems) and life is peaceful for them. Only a few days ago there was lots of conflict. They haven’t left the island today and the male pup has not returned. They have mostly moulted it seems and are waiting for their new fur to grow.

After I wrote this I saw the sea otter! He was around seal rocks for a couple of hours.

Race Rocks Ecological Reserve #97 Warden’s Report ,

Posted on by

We departed Pedder Bay on Second Nature with Greg who was taking Joan Rosenburgh out for an Ecoguardian exchange.  Before leaving we noted a new perch location on the new docks at Pearson College .

 

On arrival, a nice greeting from the group of Northern and Californian sealions near the docks

I took photos of all the adult elephant elephant seals still at the reserve :

 

 

There have been many improvements that the Ecoguardians and the college staff have done since the last time i was here.One important improvement has been the installation of a new toilet system which seems to be a big improvement over past models.

I was interested in relocating the spot where a new geo-positioning system was installed last year, since I had been unable to locate it one time when i was out there. So these pictures are for future reference for relocation. When scientists come out to recheck , the results from satellite triangulation at this spot can indicate the amount of tectonic plate movement .

 

 

 

Spring is in the air

Ecological Notes:

  • 4 Elephant Seal on the main island
  • The Male Beachmaster (Bernard), 2 Adult Females, and 1 weened Male “pup” (very large now!)
  • The last pup had grown to almost double the size he was when I got here, and  I had hoped to report he was doing well, but unfortunately the nature and the Beachmaster had other plans. The (female)pup passed suddenly about a week ago and was returned to the sea today. Samples were taken for analysis, including hopefully testing for DNA to check paternity.
  • 1 California Sea Lion noted with rope entanglement. He is surprisingly active for the depth of the wound. Reported to the Marine Mammal hotline.
  • On a more positive note, the Black Oystercatchers are paring off, and some Gulls are wondering around showing off nice clumps of grass they have collected to whoever will notice.

“See my stuff????”

Visitors:

  • A couple of visits from the shorefront coordinator, delivering groceries, parcels, diesel fuel, and parts for repairs.

Facility Work:

  • After a couple attempts to repair the existing connections from the outside line to the pump, it was decided to just replace and simplify the pipes ….. to a final success.
  • Repaired the VHF Antenna on the main house, applied tape to hopefully stop it from vibrating the threads free in the wind.

DND events:

  • On and off all week, except the weekend of course

Noted Vessel Traffic:

  • Several Ecotourism vessels enjoying the sights and sounds of the reserve.

Responsible viewing and educating

  • With the nicer weather, several kayaks and outrigger canoes have looped out around the reserve, experienced paddlers who all stayed out of the main channel in the reserve where currents can be strong.

 Noted Infractions:

  • Some private fishing very close to the reserve, but measurements with a laser rangefinder suggest they were just outside the 40M depth contour.

Weather Events:

  • A mixture of winds, but mostly light days with mostly sun for the last couple days.

Many Visitors at Race Rocks

Posted on by

Ecological Notes:

Race Rocks is a wealth of biodiversity, and an amazing place to get to spend any amount of time. Despite the huge amount of wildlife that spend time on Race Rocks over the winter, it can feel a little quiet. Not last week!

We were super lucky getting some of the Pearson College students out despite COVID lockdowns on Campus, this is always one of the highlights of our time at Race Rocks! The kids always have the best questions and remind me why I pursued the life I live now. Any opportunity to share the joy and smells of Race Rocks.

After the final group of students left, we got a surprise visit from DFO via their helicopter coming by for a socially-distanced visit. We had a helicopter buzzing us throughout the week, and it wasn’t until it landed at the end of the week we realized that was most likely the crew checking out the island, seals, and heli-pad. The elephant seals clearly weren’t fans of the helicopter. Interesting-ly the idling helicopter covers the same sound frequencies the Beachmaster uses to drum his dominance. Our Beachmaster tried drumming at the intruder, but he couldn’t overpower the sound and decided that abandoning his harem and a trip into the ocean was preferable to hanging out with a helicopter.

The next day we woke up to a new female Elephant Seal! We suspect this seal was Tyra from last year, going off her scar patterns and BEAUTIFUL eyes. At this point in the season we have expectations for these seals: they come ashore, hang out for 5 days, give birth, nurse for 21 days, mate and leave. Tyra was a reminder that we don’t really know that much about these mysterious animals. She came ashore, mated, and left. She looked great, very plump. I am really quite surprised. Maybe not all pregnancies come to term, and in that light her behaviour actually makes a lot of sense. She needs to come ashore when a Beachmaster is ready to mate, and if she doesn’t have a pup to birth then there really isn’t a reason to stick around and wait until it’s time to moult.

Tyra returning to Race Rocks to visit the Beachmaster. All hail the Beachmaster!

And we had a new pup born! I told you lots happened. Rhi-Rhi has been ashore since January 25th and slipped out a new pup this morning. The new pup is super chirpy, and very mobile; it had a very ‘rolled up’ vibe directly after being born, with curled fingernails and it’s giant flippers wrapped around itself. We expect her to nurse until the 22nd of February, but clearly I need to stop trying to predict what these animals are going to do.

Rhi-Rhi inspecting her newborn pup.

Facility Work:

Race Rocks has a Boston Whaler from it’s Coast Guard era that can be used in case of an emergency. During a very low tide we figured this was the ideal time to re-spool the twisted up cable used to launch the boat. While it’s easy to think that emergencies never happen, it’s great to know that in that hypothetical situation the boat will be able to be launched on any tide without any problems. Big thanks to the previous Eco-Guardians who did some great boat maintenance!

DND events:

Lots of blasting over the last week, some of the Pearson College students were definitely surprised.

Elephant Seals seem happiest when all smushed up against each other.

Feature Event:

We had someone report a wayward Elephant Seals wandering around Sturdees Beach & the Gorge vale Golf Club. This fits very well with the theme of ‘we don’t really know much about Elephant Seals’ and thought it would be worth mentioning. As the Northern Elephant Seal population continues to recover, hopefully we’ll all get to experience more Elephant Seals in British Colombia, and sometimes that might be a returning pup who hasn’t really figured out the timing of things yet. They’re really remarkable animals, who spend a very small proportion of their time (<10%) above the water Over the last 2 years there have been wayward pups reported crawling around in areas where they were not wanted, these little seals are just looking for some place safe to moult and head back into the ocean. This is one of the parts that makes Race Rocks such an important place for these animals: a place on land where the seals can hang out and sleep without being disturbed: their time on land relies on them fasting for weeks on end losing up to 40% of their body weight during these stints. Every time they get woken up or stressed that is another drain on their limited energy available, leading to the first couple of years where mortality can be up to 75%.

The silver colouration shows this wayward pup has already moulted, so probably from last years birthing season. While we would expect pups to return to Race Rocks to moult, we don’t really know how they return to the same areas, and they may just try out new areas at different times; or just get lost.

Weather Events:

It was a lovely week of weather, punctuated with a nice little blast of wind of 40 knots+ Sunday and Monday.

New Elephant Seal + Pupdate

Posted on by

Rhi=Rhi came back and is ready to birth!

Ecological Notes:

We have a new female Elephant Seal on Race Rocks! While she looks suspiciously like one of the returning mothers, without a tag it is hard to tell. She was thoroughly investigated by our local Beachmaster, and sassed Mikey for getting too close. Mikey seems to have learned his lesson to stay out the Beachmasters way, after a few small bites Mikey is now quite mobile and has learned the paths on the island to avoid further conflict.

Lil Blasty in one of the few moments not blasting squawks.

As for the other Elephant Seal Pup: named Nereo by it’s mothers namesake, but I have been referring to it as ‘Lil Blasty’ due to his extreme volume while ‘chirping’. The current theory is that Elephant Seal moms and pups learn each others vocalizations to identify each other, and regardless of the background noise present, they seem to always vocalize at the same volume.

Jocelyn’s vocalizations come in around 50-70db, where Lil Blasty is clocking in at 100-110db with his vocalizations. For reference: WCB recommends not being exposed to over 85db for prolonged times due to hearing damage. It definitely hurts to be outside when he’s shrieking.

The Beachmaster being grumpy that no one wants to mate with him.

Facility Work:

We bucked up the logs that were snagged over the last week, and got them off the boat/seal ramp. Heavy algae growth over the last 2 weeks so we’re started pressure washing the algae to keep things from getting too slipper.

DND events:

Canada’s Navy has started doing tester laps outside of Esquimalt.

Feature Event:

Mikey has learned to avoid the Beachmaster when he’s on the prowl, and decided to explore off the beaten path to avoid any conflict. We suspected he would fall off the ‘mountain’ climbed today, but displayed some remarkable manoeuvrability for a chubby little seal.

Mikey mountain-climbing.

A hallmark of the maturing pup is the wear-pattern on their chins. The chin is a key instrument for Elephant Seal locomotion: where they re-arrange their belly by lifting it up with their chin. The chin can also work to level the seals bulk up onto rocks, steps, and rough terrain.

Mikey starting to show his all-important chin patch.

Weather Events:

January means the start of some epic sunsets.

The last couple of days the temperature has dropped down to 4°C with light N winds around 10-15knots. This is log weather.

New Baby Elephant Seal

Posted on by

Typically the newborn Elephant Seals don’t move their heads around much after birth, but this new pup seems to have something to prove.

Jocelyn decided to give birth this morning, after spending 5 days sussing out the island. This is the same time spent on land as the other mom this breeding season, and the same timeline this seal had last year. These seals having remarkably consistent timing!

The new pup seems incredibly well developed and mobile, and immediately after getting born started squawk-chirping this our resident wean-ling Mikey. While some Elephant Seal mom’s can be very protective of their young, Jocelyn seems very chill about having another pup hanging out around her.

Elephant Seal Swapping

Posted on by

Mikey is all on his own, exploring the island mouth-first and trying to avoid running into the angry Beachmaster.

Ecological Notes:

Beverly wrapped up her time nursing her pup, mated a couple of times, and headed back to the open ocean to recover her lost weight. She spent 27 days on land, nursing her pup for 21 days, the exact same number of days as last year. She has remarkably consistent timing.

Beverly and Micheal Day 1. Starting around 500kg she’ll end up losing around 200kg throughout nursing.

Beverly and Micheal Day 21. Beverly has lost around 40% of her weight throughout nursing.

The next working we woke up to the bellowing of a new pregnant elephant seal, timing and characteristics point to this seal being Jocelyn (another return from last year), but she is not tagged, so we’re guessing that it’s her by comparing photos of identifying scars. This is a day later than she showed up last year, and we’re excited at the prospect of another elephant seal pup! After 5 pups last year the thought of only having one pup born here was pretty disappointing.

The seal we suspect is Jocelyn, she is soooo big I’m surprised she could make it up the ramp.

For those interested, the Beachmaster mated with Beverly 27 times 4 days (that were noticed/documented). It’s an impressive feat for sure, but seems to depend on the exhaustion that sets in towards the end of nursing. On bigger beaches a Bachmaster can have a harmem of 30-100 females, so only having 1 or 2 females to mate with could be related to our males ‘vigour’.

Elephant Seal mating can be pretty unpleasant to watch sometimes, but it’s clearly a method that works for them or the population wouldn’t have recovered from near-extinction.

Facility Work:

After last weeks 50 knot blasting, we spent this week repairing the electric fence and picking up the pieces that blew off the buildings. We’ve had some massive high tides, as well as some logs piling up on the jetty. I’m still unsure what the actualy conditions are that contribute to the log pileup, but we made sure to snag some good looking firewood logs for next winters Eco-Guardians.

Beverly navigating the log-jam on the boat ramp.

DND events:

2 days with blasting since the last update, but it’s been very quiet. We did see Coast Guard heading offshore during the big blows, practice makes perfect!

Feature Event:

Weather – Current:

http://www.victoriaweather.ca/current.php?id=72

Flat calm weather and winds under 3 knots have been delightful the last couple of nights. We’re still trying to figure out how you can get a crystal clear sky, and enough fog to set off the fog horn…

Weather – Past:

http://www.victoriaweather.ca/station.php?

Last weeks wind scouring led to this weeks flat calm, perfect time to pick up the pieces and get ready for whenever the next storm rolls through.

 

Weaning for Elephant Seals consists of abandoning their pups on the beach. Mikey didn’t enjoy that much, and screamed for the whole first night before accepting his independence.
