Entangled Sea Lion and Oct 20 Census

Posted on by

*WARNING* Today’s blog post contains photos of a severely entangled sea lion with deep wounds.

Well, if my warning wasn’t an indicator – today has not been the most fun day of animal spotting.

I came across a California sea lion this morning with by far the worst entanglement I’ve ever seen. What appears to be monofilament fishing net has wrapped itself so tight that its caused deep wounds on the back of his neck, as well as the rest of the way around. On top of that, the netting is so tightly wrapped around his muzzle that he doesn’t appear to be able to open his mouth.

Given that my full time job is in marine mammal rescue, seeing entangled animals is not new to me, I see them so often that I sometimes feel immune to how awful it is.

Today I am not immune, I am horrified.

All of the right organizations and people have been contacted and I know that every single one of those people will do everything they can to help him. I just hope he stays put until then.

There is a second entangled sea lion here as well, a Steller with a packing strap around its neck which is bad but thankfully not as severe as the Cali.

Moving on to today’s census….with the weather being so bad this weekend, I’m not surprised the numbers are down from last week!

Steller sea lions: 392
California sea lions: 652
Harbour seals: 41

Sunday September 8th

Today we spent a lot of time on the fence again. We painstakingly went through each section to ensure that charge was being held the whole way through. This was a very tedious process and we still don’t have the voltage up to where we want it to be…. but there have been no pinniped breaches yet, so fingers crossed!

Today, Scott and I climbed the lighthouse tower to complete our first wildlife census. As a marine ecologist, I have a lot of experience counting fish underwater. However, counting over 600 Sea lions that all look like overlapping brown logs or trying to count birds that keep on flying away or are hidden between all the sea lions was way harder. With that said, being a top the tower made everything much easier to see and to conceptualize on a greater scale.

While we were up there we also got to enjoy a couple of humpback whales engaging in tail slapping or “lobtailing” behaviour for well over 30 minutes. It is thought that the sound and force generated by the slaps frighten the bait fish into tighter schools making them easier to hunt. Based off gull activity, there were definitely a lot of bait balls around, so hopefully we will get to see more of this behaviour in the coming days!

*  Note: all sea lions on Middle Rock were counted as Stellar sealions, there may be a couple of California sea lions mixed in.

Wildlife notes:

The entangled Stellar sea lion was not spotted today on Great Race Rocks. A Stellar sea lion with a dark coloured stain around its neck (possibly a packing band), reported previously by naturalists on the ecotourism boats, was sighted on Middle Rock during the census.

The Stellar sea lion on Middle Rocks with a possible new entanglement is located in the bottom centre of the photo and has a dark coloured ring around its neck.

I wish I could sleep like a sea lion, on any surface, cold, hard, flat or bumpy and with only a log for a pillow.

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%)
Western Gull 4 (1.01%)
Visible pairings 44
Glaucous-winged + Glaucous-winged 2 (4.54%)
Glaucous-winged + Light Olympic 6 (13.63%)
Glaucous-winged + Intermediate Olympic 3 (6.81%)
Light Olympic + Light Olympic 14 (31.81%)
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.
The other non larid species present
1 Canada Goose
3 Harlequin Duck
11 Black Oystercatcher
2 Killdeer
8 Rhinoceros Auklet
254 Pigeon Guillemot
3 Brandt’s Cormorant
23 Pelagic Cormorant
1 Bald Eagle
2 Barn Swallow
Pinniped abundance and usage of the area
2 Northern Elephant Seal – two immatures one small and one medium sized.
59 Harbour Seals
2 California Sealions
Map of nest locations.
Next time we will also log unidentified nests.
Any other questions or feedback is welcome.
Thank you,

Notes for Day 2 at Race Rocks

Census day

After the morning cleaning of the panels I decided to wander beyond the electric fence.  Surely it wasn’t meant to keep me in and how else could I complete the census.  It was liberating wandering about and I even peered into a spectacular tide pool. I am used to different methods walking in certain terrain: through the sprawling yellow cedar or “shin tangle” of coastal BC bogs or the Tuckamore of Newfoundland, you bob and weave, through Devil’s club it is more like Thai Chi. Today I learned how best to walk with the birds.  I started with the head down, quick and deliberate, travelling from one small gull free patch to another. The better approach is to travel very slowly, only a few steps at a time then have a long and still pause. I observed many nests during my slow walkabout and was surprised by number of the poorly formed or empty ones. There are often bursts of commotion when all the gulls take flight but I haven’t yet seen an eagle at that time or any other obvious cause for the scare. Even though I feel more comfortable walking past or through hovering gulls, I still wear my helmet and often carry a broom over my shoulder.

My day ended watching the cormorants leave in the fading light.
