A Quick Week on the Rocks

A week goes by quickly out here!  First, an update:

The branded Steller’s sea lion I reported in my last post has a history that includes a previous trip to Race Rocks. 746R was branded at Rogue Reef (Southern Oregon) on July 12, 2009.  He has been all over Carroll Isl WA, Graves Rock SE AK, Castle Rock CA, Barkley Sound BC, Race Rocks in 2016, Sucia Island WA, Ewing Isl WA and Cape Arago OR as recently as July 7 this year. This and other marked sea lions are being studied by Susan Riemer of the Oregon Department of Fish and Wildlife. If you see marked sea lions, she really appreciates hearing about your sightings.

The last few days have had all of the weather possibilities for this time of year except hot. Foggy much of the time, windy most of the rest, and sometimes foggy and windy just to change things up. No rain, but humidity in the high 90s.  I’m always struck by how different the temperatures can be just a couple of kilometres away. The wind yesterday actually broke the electric fencing tape on the jetty, which I fixed this morning.

Despite the wind, it’s been a good week for shorebirds.  Another new one for me here (but not for Race Rocks) was a Sanderling. Normally seen chasing and being chased by incoming waves on a sandy beach, they do spend some time in more rocky environments.

The thick stubby bill and “spangled” back pattern are characteristics of Sanderling

The red colouring on the neck had me hoping it might be a MEGA rarity, but it was not.

The predominant gull at Race Rocks this time of year is the Glaucous-winged Gull. They are the regular breeders in this area.  But gulls don’t necessarily stick to their own kind. When they hybridize with Western Gulls, the offspring are known as Olympic gulls.  When they hybridize with Herring Gulls, the offspring are known as Cook Inlet Gulls. There is a gull that I’ve been watching that I think may be one of the latter.

Note the white “window” in the outer primary feather

The orbital ring is orange-yellow like both the Western and Herring gulls. The iris is darker than a Herring gull and lighter than most Glaucous-winged Gulls.

I’ll be passing these and other photos on to someone more “gullible” than I am!

The Second Nature from Pearson College has been making the rounds with alumni and friends of the school. Some of them had to look hard to find us through the fog!

Thanks to Greg Dickinson and Pearson College for providing this opportunity to me again.

Visitors:

  • No visitors ashore, but several from Pearson College on boat tours around the rocks
  • Ecotourism traffic has been picking up, despite the fog.

Facility Work: 

  • Cleaned windows and solar panels daily
  • Cleaned outbuilding windows inside and out
  • Swabbed the decks at the Ecoguardian residence
  • Fixed a shock-inducing break of the electric fence on the jetty
  • Visually checked the entire run of the fence and reconnected tape blown out by high winds

Aug 2 – Census surprises

One of the reasons for doing a weekly census is to put down in writing the numbers of mammals and birds that are actually in the reserve. This gives us the opportunity to compare the results, not simply rely on memory. And that’s a good thing!  My impression on my return to Race Rocks is that there were a lot fewer gulls here than last year.  A check of a census at a similar date in 2022 shows that not to be true. The numbers are actually very similar, but down about 15% from the same period in 2021. Census records the high counts of each species observed during the day. The marine mammals, for instance are best counted at low tide when most are hauled out. The adult gulls are at their highest numbers first thing in the morning and shorebirds gather on the east beach in late afternoon. Gull chicks can be counted anytime, but are usually undercounted because of their great hiding skills. In between, the census person watches for any other birds and animals that might show themselves.

Today’s census had several surprises apart from the number of gulls. While on the jetty, I thought I caught the flash of a bird in the corner of my eye.  It was more than one. At least 3 swallows were feeding on insects in the small bay beside the jetty. I managed to get some bad photos, but good enough to identify two different Barn Swallows and one Violet-green Swallow. Later in the day, a Lesser Yellowlegs was resting with the other shorebirds, and a Parasitic Jaeger (also identified by bad photos) headed west not far off Great Race. An adult and juvenile Glaucous-winged Gull were out for a little swim.  It always amazes me to see these youngsters in the water!

Lesser Yellowlegs, possibly the first documented for Race Rocks.  First on eBird for the Race Rocks hotspot.

Out for a swim

Among the sea lions today, I found one entangled with a fishing lure. This poor animal has been her for several weeks. Another had been branded for a research study. I’ll report this number to get its history.

Back on the Rocks!

I am back on Race Rocks for the next two weeks, having been away since August. Greg drove me out yesterday afternoon in the boat Second Nature, arriving at 15:30. After unloading my gear and food, I reacquainted myself with the island’s building, systems, and other species.

There are two elephant seals on the island. One sub adult hauled out on the boat ramp has two green hind flipper tags labelled H999 and K646. They mentioned by Derek on the April 1, 2023 census: https://racerocks.ca/animal-census-31/. Green tags usually signify the seal was tagged as a pup at Ano Nuevo Reserve, near Santa Cruz, California. I have put in a request with the researchers there to find out about the sighting history of the seal. The other seal here right now is a female adult, who has been hauled out near the bushes on the centre of the island and made some trips to the water, was probably one of the mothers from the winter breeding season.

The most populous birds right now are the few hundred nesting glaucous-winged gulls and chicks. There are still many nests with eggs yet to hatch. The pigeon guillemots are active in a few places around the island: near the jetty, blasted rocks north and west of the helicopter pad, and the south side of the island. I have yet to see any oystercatcher chicks or the barn swallows that have been seen recently.

Weather for July 7 afternoon and evening:
Wind: W 32 knots
Visibility: 15 NM
Sky: Clear
Sea: 3′ chop
Air temperature: 14 C

Weather for July 8:
Wind: W between 10 and 31 knots
Visibility: 10-15 NM
Sky: Partly Cloudy
Sea: rippled in morning, up to 3′ chop in afternoon
Air temperature: 12-15 C

I gave the solar panels a good scrub this morning to get off the built up gull guano. I have also been monitoring the freshwater levels after a couple recent leaks that have been fixed.

Here are some photos from the past two days:

The beginning of nesting season

I am here for four days to give Jillian Brown a chance to attend to her family. It is a special time for me because it is my birthday and the fourth time that I have been here on April 30 but only my second time in the capacity of eco-guardian. This is my third day here and I have updated the SOP to include the up to date log sign in details (Thank you Garry).

The weather is currently 15 knots west but over the past day has been as high as 30 knots, SW and NW. The sky was clear for 2 days and there was enough energy provided from the solar panels to take care of electrical needs.

Below is a picture of a tagged glaucous wing gull that I saw the May 22,2022 (see log entry that date)  in the exact same place. Although this may not surprise you it made me feel like the animals here are familiar. It does seem like the geese nesting by the fuel shed are the same aggressive geese as last year and the ones under the keeper’s house stairs the same mellower geese but I just never had proof. This gave me a feeling of community.

There are 6 elephant seals here, females and immatures, including the tagged yearling. I haven’t seen this year’s pup for 24 hours so perhaps all the newborns are now gone.

Visitors

Yesterday (April 29) I was surprised when 6 kayaks pulled up the jetty. They were from Pearson College and had been given permission to land. Of course the sea lions stampeded on their arrival. Luckily not many kayakers do come this way as the sea lions usually get right in the water even though motor boats come much closer without scaring them. Perhaps they should turn some music on LOUD as they approach?

There were only 2 or 3 ecotourism boats over Friday and Saturday but today there have been 8 in every size, perhaps tied to the massive cruise ship recently docked in Victoria?

Maintenance:

  • I am working on the wood pile, chopping and stacking in the house.
  • Swept the lamp room and continued sweeping the light house stairs.
  • Filled the batteries with distilled water.
  • This is month end so sent the salinity and temp chart to Sebastien Donnet.
  • Also have almost completed the month end report but need to review a few details with Greg.
  • Sent the info of tagged bird info to appropriate source.

 

 

 

 

 

August 22 and 23

Both Monday and Tuesday were foggy for much of the day, as can be typical in August.  At about 11 am on Tuesday, the fog signal stopped sounding when the fog was at its most dense.  The Coast Guard and nearby marinas were notified.  Most boats have GPS and/or depth sounders so a grounding was unlikely but still a concern. It started up again at 1 pm, then off again an hour later. The Coast Guard hope to be able to come tomorrow to repair it, but in the meantime a navigation advisory has been issued.

Ecological Notes:

  • The alpha male elephant seal has been present both Monday and Tuesday, but the young female headed back to the water sometime late Monday or early Tuesday.
  • Steller’s sea lion (431Y) was seen again on Tuesday.
  • A Short-billed Dowitcher remained on East Beach on Monday.
  • An unofficial tally of sea lions during high tide on Tuesday evening produced a count of 456 (not separated by species).
  • A Common Murre was seen aground beside the jetty on Tuesday afternoon. This is an unusual behaviour for this species away from their nest site.
  • See photos below for more ecological sightings.

It was a short but great stay for Carl and Brady Hughes. They managed to see all of the expected mammals and got to know the Glaucous-winged Gull community quite well during their visit. Carl spotted the season’s first Sooty Shearwater on Saturday and attempted overnight audio recording that night. He will post his recordings to iNaturalist and eBird. The compost rejuvenation project continues with 48 more buckets of aged compost removed from the first chamber.

Ecological Notes:

  • All three elephant seals were seen on August 14 and 15.
  • Passerines seen in the last two days were Brown-headed Cowbird, Barn Swallow and Northern Rough-winged Swallow. A Northern Harrier flew north over Great Race on Saturday.
  • A juvenile Short-billed Dowitcher was wandering the paths in the fog on August 15.
  • The branded Steller’s sea lion sighted on August 12 has a history! Originally branded at Rogue Reef, Oregon in July 2003, he has been sighted at least 70 times. Previous sightings on Race Rocks include Dec 2007, May 2008, Sept 2009, Aug 2014, and Aug 2017. The most spectacular resighting, though, involved an escape from a pod of Orca in the San Juan Islands in 2020.
  • Humpbacks and Orca are being seen regularly, but generally at great distance.
  • See photos below for more ecological sightings.

Gull Chicks Everywhere

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.
