All in the day of a gull

Posted on by

The elephant seal typically spends his mornings sleeping the grass near the east-west walkway leading from the Jetty to the Energy house. In the afternoon he moves to the east side of the house perhaps seeking the shade. He often moves in quick short bursts and with no regard to the gull nests in his path.  Today I watched him place himself on top of a nest near the house.

The gulls go to have a look for their nest which is mostly beneath him.

His first warning

The gulls try to persuade him to move

and try

and try

 

 

The seal reaches but can’t manage to grab the gull out of the air.

 

Eventually the seal moves a bit and the gull can take a look

They remove the shell pieces…..

and they eat the rest!  A few minutes later, she back on the nest as though nothing happened.

Facility work:

  • cleaned solar panels: from 12-1 pm generated 7.1kW !
  • thistles
  • chopped kindling

Wildlife notes:

Several eagles visited throughout the day causing great commotion. The oyster catchers seem to be the first to raise the alarm.  The California sea lions were notable absent from their regular spot near the Jetty. The four Canada geese are still here.

Vessels:

7 Ecotourism boats

Weather:

Another sunny day, winds WNW 10 in the morning building to W 30 midday.

Thistles

Thistles:

During yesterdays visit, Garry Fletcher remarked on the expanding thistle population around the tower base and suggested they be pulled. Today I started to tackle this job.  The thistles have a tap root that connects to a horizontal root which can spread many feet.  The thistles are growing in patches where many of the plants could be connected to the same horizontal root.  When a larger plant is pulled, the tap root breaks at this junction and reveals the depth of the horizontal root.  The longest root so far is almost 10″ long suggesting there is in places 10″ of soil on Great Race Rock! Only the smallest of plants, which may have germinated from seed, can pulled with the entire root intact. Today I cleared 2 square meters – a bucket of small ones and bundle of larger plants.  I plan to do this amount each day (more would be too hard on the back). I may not finish before I leave but with the horizontal roots still in the soil, this may be a yearly task.

Developing thistle flowers and the longest root of the day.

Facility work:

  • cleaned solar panels
  • thistles
  • split rounds of firewood

Wildlife notes:

No new wildlife sightings to report. The gulls continue the mate and fight, and the Elephant seal spent his day sleeping in the grass.

E-Bird June Race Rocks gull survey and Census

Posted on by

E-Bird Gull Survey https://ebird.org/checklist/S184107190

Subject: June Racerocks Gull Survey

Rocky Point Bird Observatory & Pearson College Race rocks Gull Survey June 2024
Survey conducted by Andrew Jacobs and Ann Nightingale
Thank you to Greg for getting us out there again on the boat and Christine with the assistance during the survey.
This survey was conducted to investigate the phenotypes of the glaucescens-occidentalis hybrid complex using the Great Race Rock as a nesting area. We looked for pairing preference of phenotypes, nest habitat preference and mapped the nests that had parents on them. We looked at the breakdown of the colony diversity into five phenotypic groups – pure type Glaucous-winged Gulls, Glaucous-winged trending hybrids or light morph Olympic Gulls, intermediate trending hybrids or intermediate morph Olympic Gulls, Western trending hybrids or dark morph Olympic Gulls, and pure type Western Gulls. The nesting of Western Gull on the island is of specific interest as there are adult Western Gulls near the island year round and we would like to see if Western Gull pairs are starting to breed in Canada or if they are forming mixed pairs.
The survey also counted other species of gull and age classes as well as other species using the rocks this time of year. The general nesting grounds on the main rock were used by the hybrid complex, Pigeon Guillemot, and Black Oystercatcher although no nests of the latter two were seen they were displaying as if nests were nearby.
Ebird link with photos and sound recordings.
The numbers of pure type Glaucous-winged Gull were up for the breeding season over our previous survey by about 6-7 times at 69 individuals with 64 adults and 5 immatures. The number of hybrid and intergrade type Olympic Gulls was 321 with 314 adults and 7 immatures. The breakdown of colour morphotypes in the Olympic Gulls was light morph (Glaucous-winged trending hybrids) 138 individuals with 133 adults and 5 immatures, intermediate morph (Intermediate trending hybrids) 166 individuals with 164 adults and 2 immatures, dark morph (Western trending hybrids) 17 individuals with 17 adults.
The island at this time contained 4 adult Western Gulls, two of which were on nests, one was in the grassy area on a rocky outcropping and one was on the outer rocky part of the island along the cliff. The two nesting Western Gulls did not have a partner present while we were on the island. Surprisingly one of the Western Gull nests appeared to have a rock placed in with its three eggs in the nest of roughly egg size.
Total glaucescens-occidentalis hybrid complex birds 394
Glaucous-winged Gull 69 (17.51%)
Olympic Gull 321 (81.47%)
-Light morph 138 (35.02%)
-Intermediate morph 166 (42.13%)
-Dark morph 17 (4.13%)

Light Olympic + Intermediate Olympic 5 (11.36%)
Light Olympic + Dark Olympic 1 (2.27%)
Intermediate Olympic + Intermediate Olympic 11 (25.00%)
Intermediate Olympic + Dark Olympic 2 (4.54%)
Banded individuals included three Olympic Gulls one colour banded adult (cobalt blue over metal right leg and red over cobalt blue left leg), and one adult and one immature with metal bands.
Other Gull species in the survey area included California Gull with 3 immature individuals and Heermann’s Gull with 4 adults.

New to the Rock

Posted on by

Today is my first day as the Ecoguardian at the Race Rocks Ecological Reserve. I was dropped off at 8:30 am with my personal gear, bags of groceries and a reminder to monitor the solar panels, batteries and the electric fence – there are more duties and responsibilities but a source of power is one of the essentials.

Power

I unpacked, put groceries away and set off to tackle the my first chore – clean the panels. The solar panels are mounted on the roof and on the side of the Energy Building which houses the diesel generator.  At this time of year, with the long sunny days and daily cleaning, it is possible to power the house systems just on solar power.  Why the daily cleaning? There are hundreds of gulls nesting here and what do we will do at least once a day? Poop!

Panels on the Energy Building roof

After hauling the cleaning supplies up to the roof and turning on the water, I thought a methodical approach would serve me best. I climbed back down and noted my “starting point” of 3.1 kW of energy being produced by the panels.  After cleaning four panels, I climbed down to check the display.  It was up to 3.4 kW.  Cleaning is one of those tasks that provide instant gratification and now, doubly so.  With all the roof panels cleaned they were producing 4.2 kW and with lower side panels it was up to 4.8 kW!  I tell myself “what a worthwhile task and job well done Christine”

Well, later in the day I have some time to sit down and familiarize myself with OPTICSRE, the software package that lets you visualize your energy system production (solar or generator), storage (battery bank) and consumption levels. It turns out that in the long time it took me to figure out the best way to clean the panels and finally get the job done (between 10 am and noon), the sun was moving, as it does everyday, and with the clear skies, was naturally approaching its peak midday production levels (see graph below). Silly me, it wasn’t all my doing!  Shame there is no easy way to determine the added benefits of cleaning the panels.

OPTICSRE graph of energy levels produced by the solar panels (green bar), stored in the batteries (dark blue bar), taken from the battery by the house systems (light blue bar) for each hour on June 11.

The software also displays live time power use. I consult this throughout the day and find it memorizing.  The image below shows the current situation at night as I write this. Very little energy is going from the panels to battery, the batteries are at near full capacity and we are operating in the red, drawing power from the battery bank.  The house (appliances, computer, lights etc) generally draw 1.3 kW of power. If I turn on all the lights in the house and the bathroom fan, it jumps to 1.5 kW. I think if we had such a monitor in our homes, we would be more aware of our consumption and our footprint.

Heads to the wind

The another thing I discovered today was all the gulls were facing the same way because of the wind!  We went from light winds at 8:00 am to 41 knots with gust of 46 by early afternoon. Like me, if standing, they took a wider stance, arching and bracing for the gusts. I watched one trying to move travelling side-to-the-wind and being blown off a rock; most scuttle side-ways like crabs.

A very interesting first day.

It is a privilege to be here.

 

 

Gulls, Gulls, and More Gulls

Posted on by

If you told me 6 months ago that I would one day be interested birds I would have called you crazy. Yet here I am, going cross eyed as I flip through every bird book on the shelf trying to decipher which gull is which and how to identify their various life stages. 

It started this morning when I saw a brownish/grey bird I’d never seen before fly by. It had a stumpy looking neck/head and its wings seemed almost stiff as it flew (if that makes sense). I only managed to get one terrible photo of it through the window and I have spent the majority of the day consulting colleagues and books trying to figure out what it was. I’ve got it narrowed down to a few options and will post a photo of it once I am confident in its ID.

From there I sat on the rocks with my camera hoping it would show up again and in the meantime snapping photos of the gulls – who by the way are still not acting aggressive in any way when I pass their nests. I took a photo which I’ll post a below in which there seems to be multiple different gulls but I really started going down the rabbit hole when I was trying to determine if they were different species or just the same species at different ages. Thankfully one of my relatives is a bird expert and photographer and was able to help me with a few!

Sunday Update

Posted on by

There were about 50 sea lions on the rocks out front when I went to sleep last night, and I think all 50 of them decided to be particularly chatty from 4am onward. Needless to say, today ended up being an early morning start for me be but I’m glad it was! I opened my bedroom curtains to find about 15 brown pelicans resting on the rocks outside my window. I crept outside with my camera being careful not to disturb them and then sat on the back porch in the mist and watched them preen and dry their wings. I think I could stare at pelicans forever, they’re such funny looking creatures.

 

The Swiftsure International Yacht Race continued throughout the day with all boats on their way back to Victoria. Unfortunately the wind was at 0 knots and the ebb was strong so some of them appeared to be going backwards. Slowly I watched boat by boat as they admitted defeat, bringing their sails down and starting their engines. A few persevered but the same boat I saw at 7am was still bobbing outside the reserve at 1pm, trying its best to get past the currents.

Back to the animals —we are down to two elephant seals now, just one big and one small female. The gulls have officially started laying eggs which I know because one was dropped outside my front door this morning. They haven’t shown any aggressive behaviour towards me yet but I imagine I’ll be ducking for cover any day now. Ollie is still doing his best to blend in with the harbour seals, his bed of kelp and seaweed looking especially cozy today.

The weather today stayed windless with dark clouds and on/off rain. Quite a few ecotourism vessels passed by today, this time they did not bring the whales with them. Also noted a couple private vessels and one kayaker, all respecting the rules.

Happy Friday!

We have been down to just 3 elephant seals the last few days! The two small females and one larger one are still enjoying the grass, however the largest female has not been around in a few days. The last I saw of her was 2 days ago when she was bobbing around in the water behind the student house, so I wonder if she’s just chosen to haul out on one of the surrounding rocks.

Ollie spent his day in the water near Middle Rocks, just floating and looking extra fluffy.

The Stellers were no where to be found today but the California sea lions have spent the week tucked in to the left of the jetty. They must be smarter than they let on because that area is definitely the most protected from the wind. They still require the occasional reminder to stay off the jetty throughout the day but otherwise behave themselves.

Lastly on the mammal side of things, the harbour seal numbers seem to have grown since I was here in March and with pupping season just a few weeks away I hope to see that number grow before I leave in June!

There are tons of pigeon guillemots around lately, I love to watch them on the rocks and I think my favourite thing about them is that their feet perfectly match the inside of their mouth. 

Hopefully this wind dies down in the next few days and I can get back to taking more photos!

Pelicans Galore!

Today started out sunny with no wind which was a lovely change! A big fog bank rolled through in the morning but thankfully didn’t stick around too long. Cedric stopped by with 9 guests for a tour which is always fun. I love being able to talk to people and tell them about this history of the island, my job, and of course all the seal facts possible!

I got some outdoor work done (without the feeling like I was going to blow away) including giving the solar panels a good clean. I think we are almost at the time of year where this becomes a daily task. Despite the wind we’ve had a ton of sun and I have only used the generator a few times since my arrival at the end of April. These long sunny days are so wonderful!

The wind picked up in the afternoon, but not before a flock of 16 brown pelicans took a lap around the reserve before flying back out to sea! I don’t think seeing them will ever get old.

Visitors:

– Cedric + 9 guests

Vessels:

– 3 Ecotourism

Weather:

  • Sky: Blue skies and sunny
  • Wind: Low of 9 knots, High of 20 knots
  • Sea: Calm most of the day, small whitecaps in afternoon

by Eco-guardians Allen ilka Olsen MONDAY 15 April
Still windy. What a difference a day makes! At 7.15 only a single sealion on jetty (mature male
Cal); only 11 sealions on rocks near jetty/nine relocated to Middle Rocks. The ‘Two Sisters’
moulting Elephant seals separate but reunited and tucked into vegetation for wind protection.
Single moulting Elephant seal inactive most of day. The seal reported by Joan last week to Van
Aquarium not seen again.
Lots of freighter traffic—7 at once. Now watching for HMCS Max Bernays, new arctic patrol
vessel, to arrive at Esquimalt @1030. Failed to see its arrival, however a navy frigate was
observed. As well, US Coast Guard. Only one private vessel came in the turbulent seas.
Maximum flood today extremely dramatic with standing waves.

Cormorants and guillemots feeding in north water. Immature eagle on rocks next to jetty
keeping 50 guillemots from favourite, sunny east-facing perch. 20 Oystercatcher on seal rock
this morning; 10 surfbird; 6 Harlequin
Spent windy day (41 W/62 gusts) observing animal behaviour (and later in week):
1. Sealion— 18 mostly Cals have remained on rocks near jetty. 25 mostly Stellers have
relocated to Middle Rocks. On Saturday observed 18-20 sealions in water west & near
South Islands all day simply floating; occasionally one would swim staying nearby. They
remained there until dark but were gone Sunday morning. Observed this behaviour with
8 on Wed; group would occasionally go into herding mode.
2. Elephant seal—Moulting large females (?) very attached to each other; one observed
grooming/rubbing itself on the one less advanced in its moult. One quite vocal when
separated from the other. Youngster stays completely away from The Sisters (so
named by Joan).
3. Stellers roar; Cals bark; E seals honk/snore/growl/trumpet (played poorly).
4. Oystercatcher—single bathing in inter-tidal pool.
5. Surfbird—10 bathing in inter-tidal pool.
6. Eagles—three immature perched shoulder to shoulder on Turbine Rock; three more
immatures shoulder to shoulder on West Rock. Odd behaviour. A single elsewhere.
7. Cormorants leave the Rock each evening to roost (on DND land?) and return in droves in
early morning.
