Wildlife notes

There must have been a bounty in the kelp beds midday as most of the gulls except those on nests were out there for a feast. They gathered in the kelp beds on the north and north east side but not the others.

The glaucous-winged gulls that breed and nest on Race Rocks are present year-round in the Salish Sea. They are being studied as indicators of ecosystem health by Environment and Climate Change Canada’s Salish Sea Marine Bird Monitoring and Conservation Program. Individual birds are identified by their colour bands. This allows researchers to track their movements over time, their location preferences (site fidelity) and survival. They also collect blood and feathers samples for genetic, physiological, pathogen, parasite and contaminant analyses. Some of the birds get GPS tags so their precise movements can be followed. The project has been running since 2020. The researchers visited over 300 sites and banded over 800 gulls.

I sighted and reported three of the banded birds in June and July 2024 and two so far on June 28 and 29, 2025. The project lead Dr. Mark Hipfner says the last gull reported who was banded in Tofino is of particular interest as it was banded in its first winter of life “…so this is its first year in full adult plumage. These ones are ESPECIALLY valuable because we ultimately want to derive an estimate of age-specific survival and we also want to monitor changes in plumage with age.”

Like the gulls I reported, the majority of glaucous-winged gulls stay close to home. In their 2025 report in Map 2 (see below), they provide the travel details for one adventurous gull who went from Prince Rupert to Alaska to breed and then back again over the course of one year. That inspirational bird spent a lot time in the Copper River Delta and in the area of Kayak Island. I am envious as those are two place I would LOVE to see.

They have one more year to go in the study and will soon be able to report on gull habitat use, diet (via stable isotope analysis they can tell if the gulls feed in marine versus inland areas), physiological health, age, disease and contaminant levels. From the genomics data they will be able to determine provenance (the location they came from), population structure, and the extent of hybridization.

To learn more about this project and the banded glaucous-winged, California and short-billed (Mew) gulls, see their 2025, 2023 and 2022 reports.

As of this spring, they had over a 1000 reports of banded gulls from the public. To contribute to this project and report a banded gull, take a photo showing the bands, record date and location and send to:

Wildlife notes:

A gull nest with two eggs has been abandoned. “Perfect Perch” (last photographed on her nest on May 29) has not been on the nest for the last three days. This is something I did not observe last summer.  Strangely the eggs are still in the nest and have not been taken.

Facility work:

• cleaned the solar panels
• worked on Jetty electric fence replacing the gate parts by the steps and the stainless tie bands.

Vessels:

Weather:

• Clear skies. Moderate westerlies building to gale force by early evening! The house is quacking and shaking. Daytime temperatures: low 11, high 15. Some part of Vancouver Island are close to 30 degrees and I have a fire going to warm up the house.

I did not collected the sea water temperature and salinity data tonight at 19:00 as the wind was 35 knots.

 

 

Wildlife notes

I am preparing myself for the shock of finding dead chicks that have mistakenly wandered into enemy territory. Thankfully I haven’t come across any yet. It was a warm glorious day, a perfect day to admire the harbour seals reluctant to leave Seal Rocks until the waves finally pushed them off.  The Keeper’s house oystercatchers seem to have separated their duties. One is still on the original nest while the other is busy a few feet away feeding the chick that hatched yesterday. A rock pigeon visited today. They are not uncommon in the city or public markets, but here it was a unusual treat to see this bird.

Wildlife notes

The gull chicks are hatching! It explains why I was decorated by the Sign gull yesterday. This afternoon I discovered two hatched chicks and one egg in their nest. The first kernel in the bag to pop. By evening the new chicks were seen all over. It is helmet time for me or … walk slowly and carry a broom stick. The stick is not for swinging at the gulls but carried over the shoulder as an alternate target

Chim chim cher-ee! An ecoguardian is a lucky as lucky can be.

The Keeper’s house oystercatchers also hatched a chick today. A parent was seen on the nest yesterday so it was hatched in the last 24 hours – a day old and walking around. They had three eggs, so maybe tomorrow there may be another chick or two.

Wildlife notes

The gull chicks should be hatching any day now as they are getting more on edge, even in the areas that I frequently travel. Twice today I had to change my clothes as I was smeared head to toe in pungent poo. The Energy Building and Keepers house oystercatchers are still on their nests.

Shipping traffic and pollution

This is part 2 of 11 ships go sailing by.  I took these photos this morning of a ship and its extra long trail of exhaust which had not dissipated. Thinking of pollution and looking at the ships cloud-like exhaust reminded my of something I read that I’d like to share, but first a little bit about ship pollution.

There is accidental pollution from loss of cargo, fuel or oil, and there is operation pollution from the discharge of sewage, ballast water, tank washings, from anti-fouling systems, tank venting and from engine exhaust. In terms of exhaust, shipping contributes about 3% of world’s greenhouse gas emissions and 20% of the nitrogen oxides and 10% of the sulfur oxides emissions. The burning of bunker oil in the ship’s diesel engines produces the NOx, SOx, particulates, carbon monoxides, carbon dioxides, hydrocarbons, and other subsequently formed secondary chemicals … all bad, all contributing to climate change.

International Convention for the Prevention of Pollution from Ships (MARPOL) addresses the concerns of pollution of the marine environment. The requirements for nitrous oxide emissions from diesel engines, sulphur content of fuel, fuel oil quality, emissions of ozone-depleting substances, incinerators, emissions of volatile organic compounds etc, are in Annex VI Regulations for the Prevention of Air Pollution from Ships, which came into effect in 2005.

Since then the IMO set new sulfur-emissions regulations for implementation by larger ships beginning in January 2020, reducing sulfur by 80%. This should help right? It turns out, it made climate warming worse! The sulfur dioxide reacts with water vapour to produce aerosols that reflect sunlight and those clouds that follow ships, they actually help cool the oceans. This was published in the journal Nature and they suggest geoengineer and marine cloud brightening may be a viable method to temporarily cooling the climate. So…Who’d a thunk? What a mess we are in.

Wildlife notes:

There is not much to report. I found a large creamy white egg in the killing fields by the house. It was the Canada goose egg from the nest on the opposite side of house, under the back stairs.  Why the gulls would take it all the way around the house to destroy it is baffling. I wonder if she recognized her egg while looking for something to eat – it has been weeks since she ate.

Facility work

• cleaned the solar panels
• cleaned things in the house (bleached and scrubbed the south and north tiled entry ways in the Keeper’s house and other things)

Weather

Gentle southwest breeze throughout the day, moderate westerly breeze in the evening. Skies overcast, periods of rain in the late afternoon and evening. Daytime temperatures: low 11, high 14.

What’s with those spindly legs and weird knees?

Those aren’t weird looking knees on those thin sticks of a leg, they are ankles and the sea gull is standing on its toes. This form of locomotion is called digitigrade and is also used by cats, dogs and many mammals. Humans are plantigrade (we walk on our whole foot) and horses are unguligrade (walk on their hoofs – analogous to a keratinous nail or claw).

Their foot bones are fused and upright when they are standing. We see their ankle and only the bottom scale-covered portion of their lower leg bones (about 20% of the lower leg). The rest of their lower leg, their knee and shortened upper leg bone is not visible to us.

Sea gulls have three forward toes and one pointing back (the hallux which is equivalent to our big toe) but it is reduced in size and difficult to see.  Their lobation and webbing is called palmate. Some examples of local birds with the four types of webbing: Palmate (gulls), Totipalmate (cormorants), Semipalmated (herons, some plovers and sandpipers), Lobate (black oystercatcher).

Gulls are an all around great bird. They are awesome flyers and nimble, quick runners, unlike the waddling Canada goose.  And if you ever hear a person described as having “chicken legs”, you know they got it wrong.

There is a noisome odor at the outer reaches of the island, on the rocky shores, where the density of gulls have encrusted the rocks in guano. The molting elephant seal is no different – its shed skin and hair remains malodorous for years. But in the fall, the sea lions dog piled outside the electric fence outstink them all.

Noisome is Merriam-Websters word of the day and I threw in a couple more from
“10 Obscure Words for Bad Odors” – Merriam-Webster (read full version)

• Noisome – very unpleasant or disgusting
• Malodorous – having a bad odor
• Outstink –  smell worse than
• Nidor – smell of cooking or burning meat or fat
• Mephitic – offensive to the sense of smell
• Stinkaroo – stinker
• Hircine – resembling a goat in smell
• Alliaceous – smell or taste of garlic or onion
• Kakidrosis – secretion of sweat of a disagreeable odor
• Reekingly – with a reek

Facility work

• cleaned the solar panels
• I am almost done cleaning and organizing the Tank Shed – just the back of door and one more wall to wipe. Another immensely satisfying job which took many days to complete.

The Tank Shed houses the large diesel Tidy Tank and fuel drums (for the generator and furnaces), the portable water pump which gets rolled to the Jetty to pump up fresh or salt water, electric fence supplies, the unit for measuring seawater temperature and salinity, the computer for the Davis weather station, and tools, paint, grease etc.

Fog in the morning, clearing by noon and cloudy in the afternoon. Winds moderate to fresh westerlies increasing to near gale force by late afternoon. Daytime temperatures: low 9, high 11.

Wildlife notes:

I haven’t seen any gull chicks hatching yet but the gulls continue to build up and pad their nests. The elephant seals usually lay partially in the water on the boat ramp or float around the Jetty blowing bubbles. The female was in the water for a long time today and actually went for a swim. I saw her on her return trip at East Beach. The East Beach oystercatcher chicks are doing well, growing quickly and darting about. I figure they are around two weeks old. The Keeper’s House and Energy Building oystercatcher pairs are still incubating their eggs.
