Ann's Adventures

Unsurprisingly, I woke to Fogust again, but at least the foghorn was sounding. All the better for getting chores done, right? I also knew that there might be students coming, but wasn't exactly sure of the plan, so thought it best to get things out of the way early. All required duties were out of the way by 8, except for the water test, which has to occur at a specific time, and today, that wasn't after 2 pm. In addition to the fog, the wind was blowing quite strongly, which made me think about what I had brought with me that I hadn't used. All my clothes and all my gadget came into play. I had four pairs of footwear with me for an island you can cross in under 2 minutes. All used. The least used item I brought was a folding chair with a sun/poop roof. I had envisioned myself sitting in it on the solar panel roof, looking out to sea for hours. That didn't happen. It made its way to the roof a couple of times in the first days I was here, but the rest of the time, stayed waiting in the generator room.

I used the last bit of regular milk I had to make my morning cup of tea. I had powdered milk which I had mixed up and used for cereal, but it isn't quite the same in tea. Nomatter. I should have my next cup in Tim's tea in hand before the end of tomorrow. A glance out the window revealed a dark blob in the fog. What was it?

If you guessed sea lion, you are correct! A security breach! He had some up the same way the elephant seals do, using the boat ramp. The Standard Operating Procedures clearly state:

Repeat after me (hand over heart): I will actively manage the Sealions so that they only have access to the outer edges of the island and I will do my best to keep Sealions from damaging the infrastructure.

I had to confront the intruder! Fortunately, this one seemed to know the drill and moved on quite easily. While I was at the jetty, despite the fog, I was able to find another branded sea lion. This one, U958, was branded in Astoria, OR, in 2015 and had visited Race Rocks at least once before in 2020.

While I was applying the policy, Greg called on the radio and said that three of the group he had on his boat would be staying in the Science Building overnight. Although they were fully independent once set up, there were a few things that needed to be done to get them to that point. Plans change very quickly here.

I had one final project I wanted to do, and it involved bird spikes. I had poked myself on the spikes on the panels earlier on this trip, and there was one particularly problematic section where the gap between new large panels was really too small to properly squeegee the panels. I concluded that the spikes were pointing the wrong way--towards the humans rather than towards the sky. I knew the solution--L brackets to change the direction of the spikes. But where could I find some, and should I really fix this? During my snooping around, I found a roll of steel strapping. Perfect. I made some L brackets and installed them on the panels. Too bad I won't be around to see if they work better on keeping the gulls from fouling these panels, but I hope they make the life of the next ecoguardians a little easier. If so, maybe they'll be inspired to do the rest of the spikes they can reach. It was done in bits and pieces over the day, but by the end of the afternoon, I had the strips on the two panels I had hoped I could get done. We'll see if I love them when I clean the panels tomorrow.

Late morning in the fog, can you guess what happened? If you guessed that the foghorn stopped again, you'd be correct! Are you two for two on today's quiz? It wasn't as foggy as Wednesday, so I was less concerned about anyone running aground. When it didn't restart after a while, I notified the Coast Guard again. I ended up making a couple of trips halfway up the tower to take pictures of the fog gauge, which seems to be at the root of the problem. In dense fog, the gauge was reading all clear. Later in the day, the foghorn restarted, and a check of the gauge showed about the correct visibility. Guess they'll be coming back!

The wind kept rising throughout the day, and was in the high 20s by the evening, and eventually to 38 knots close to midnight. Before sunset, I made a trip up the tower and the sound was very spooky. I managed to catch some shots of Steller's sea lion 882R jumping into the ocean. Lighting wasn't great, but I think the researchers will like the series.

As I approached the ecoguardian house, another breach!! This one right through the electric fence. After returning the sea lion to the correct side of the fence, I now have another task to do on Friday. He may have made it to this side without breaking the fence, but he took it out going back.

So proud of his accomplishment!

His fan club stood by while I adjusted the fence.

One last evening look at the shorebird beach turned up the expecte Black Turnstones and Surfbirds, one still partially in its breeding plumage. There were also three Short-billed Dowitchers.

Very pretty Surfbird!

Last looks at the sea added three Bonaparte's Gulls to the day's list as well.

My plan had been to be all packed up and ready to go on Thursday night except for things I would need on Friday. Last year, a rare bird showed up just as I was packing, making me almost late for my ride back. I didn't want to repeat that. But you know what they say about best laid plans. As I write this, nothing is packed!

Mushu update:

If there's no sun, there's no point in getting up!

A few more photos from the day:

Yup, Fogust

Looks clean(ish), but actually it's a whitewashing job.

Gifts from the sea. Gulls often bring plastic to shore.

Sea lions aren't the only creatures molting.

This sea lion is entangled by a rubber band. While they are mobile and healthy, there is no way to catch and free them from the gear.

A very pretty red and white bird visited Race Rocks today, but it's not going to be entered on my eBird list. In response to the issue with the fog horn, Coast Guard personnel arrived this morning in a helicopter. Most of the young gulls on the island are now at least partially flighted, so I was less concerned about a landing than I was a couple of weeks ago when they requested information on whether it was safe to do so. Now that the fog horn was malfunctioning, there wasn't much of a choice.

Coast Guard Helicopter arriving with crew to check foghorn issue.

As expected, most of the adult and several of the young Glaucous-winged Gulls in the vicinity of the helipad took off as the helicopter arrived, but they weren't the first to leave. Many of the California Gulls on the outlying islets took to the air well before the chopper got close circling around and then returning to their spots, much as they do when an eagle passes by. The marine mammals on the outlying islets and on the point west of the Science Building took little notice of the action on Great Race.

Birds responded much as they would to a predator such as an eagle.

Young gulls were definitely in the mix.

The marine mammals remaind nonchalant about the whole thing.

What did surprise me was the action of the young, still flightless gulls. As if in response to a predator, they bunched up into a loose creche. Normally, they will still to their own territories as wandering into a neighbours will result in an attack by an adult, but with many of the parents temporarily gone, they bunched up. Even the remaining adults were tolerant and didn't attack the young that had wandered into their territories--the first time.

Young gulls grouped up in response to the intruder.

The helicopter actually landed twice: once to drop of the crew and once to pick them up. The second time, it came in from a different direction, causing the birds west of the heliport to react, but many of the adults from the east stayed put and exhibited more "normal" behaviour, i.e., attacking young that wandered too close. After each landing, it took only a matter of seconds before the gulls started resuming their normal activities, even with the helicopter on the pad. They reacted very little to the take off, and within a couple of minutes, you wouldn't even know that anything unusual had happened. The wind produced by the helicopter was much less than we get here most days. A visual check from a short distance did not reveal any injured birds.

Back to normal within seconds

I couldn't be everywhere at once, but I went to the jetty to assess the response by the marine mammals there. When I arrived about two minutes after the second take off, there were no Steller's sea lions in the immediate area, but I could see them on the rocks a short distance away. Within 5 minutes, they were bumping the California sea lions, which had largely stayed put, out of their favourite spots.

After the first landing, I returned to my solar panel cleaning and can report that there was no extra fouling done due to the disruption. All I found was a small clump of dried grass that was probably dropped by a fleeing gull.

The only deposit resulting from the first landing

The crew found no problem with the detection system or the fog horn but will be checking the data from the battery file to see if they can determine the cause of the failure.

I'm not the only one to have to wash solar panels!

Wednesday is census day, and since I didn't know how disruptive the Coast Guard visit would be, I got most of it done early. Fortunately, that also coincided with low tide, which is the best time to count the sea lions and seals. I was all set to go up the tower to survey the mammals when the fog rolled in, but fortunately it subsided within about 10 minutes and I was good to go. Since the wind was low, I could actually go outside the lamphouse to see them without the interference of glass. With the numbers of sea lions increasing, it is easier to count them from above--sort of. Look at this mass of marine mammal flesh! It is literally hard to make heads or tails out of them.

1,2, 3, 4, 5, 6, 7, oh crap... 1, 2, 3, 4, shoot!, 1, 2, 3, 4, 5, 6, 7, 8, sigh...

You get outside by scrunching or crawling through this tiny door. Once outside, it's clear that the railings that were acceptable by 1860 standards, when the lighthouse was built would not be acceptable today. I'm not afraid of heights, but I'm afraid of my own negligence, so I stepped very carefully and held onto something every time I moved. If you slipped, you definitely could fall through the railing. With my clicker blazing, I clicked all the animals I could see and took photos for a review later.

This door is about 2 feet high

Very wide openings in the railings!

The rest of census is completed throughout the day, as different species are at their peaks at different times. The Pigeon Guillemots are almost absent now. I suspect most, if not all, of the young have fledged, and they are likely safer away from the gulls. Shorebird numbers in the East Bay peak in the early evening, and my numbers are likely under the actual total as they have had to move to make room for the sea lions, and can't all be seen as they were in previous weeks. A Common Raven flew over, adding a new species to my list for the island. And of course, I was able to find a Brown-headed Cowbird.

Here is today's census list:

Bubbles was unperturbed by the helicopter, but headed down to the water between landings. He is in serious molt right now and appears to be very itchy. Marine mammal molt looks like a very uncomfortable activity, and I'm sure that the cool water was quite soothing. The outer layer of skin and fur peels away in lumps and patches, and can take several weeks. Last year, he was finishing up when I was here. It looks like he is about three weeks behind schedule this year, like so many other things.

Itchy!

It's almost like having a bad sunburn.

Tomorrow will be my last full day as a relief ecoguardian. I suspect much of it will be spent cleaning up and doing some last minute things. I think a group of students will be here as well, but I'm not sure how much interaction I will have with them.
