High Tide on Coyote Creek

I probably wouldn't have stopped on my way to Mt. Tam yesterday if I hadn't spotted the American Avocets foraging along the shore of Richardson Bay near Coyote Creek. The Black-Necked Stilts are still around, but seeing avocets in this area was a new sighting for me. They were unafraid of my presence and fed just a few feet away, scything their bills back and forth but not snagging anything I could see. Well-camouflaged Willets foraged for critters in the saltgrass, moving about on foot while whistling Wigeons nibbled on plants from the water.

The holiday auto traffic was fairly heavy on Panoramic Highway, but I had decided not to wait to go up today because of the forecast of heavy winds. Yesterday was a gorgeous day for a bike ride. On reaching Mt. Tam my odometer showed I was about 50 miles away from reaching 10,000 miles. Next month I'll have had the ebike four years. Estimates for battery life are all over the place, but mine still seem to be fine.

On the hike up to the cams I spotted the biggest jackrabbit I've ever seen. It was a sprightly hare despite its size and galloped off in the direction of my cams, then finally zoomed up the hill and out of sight after allowing me a quick photo. 

When I reached the cams I was excited to find a crime scene -- Band-Tailed Pigeon feathers in a pile -- next to the little creek. The cameras appear to have caught an attack from maybe a Cooper's Hawk, but it happened too fast, and the image is too weak, to be sure. The other interesting capture was an animal I can't identify. If we had Pikas, I might have guessed that's what it was. If you have any ideas, drop me an email (jwallphoto at either gmail or yahoo).

More Winter Surf

 

Ocean Beach, Feb. 17, 2023

Reaching the steps at 14th Avenue and Mount on my walk Friday morning, I could see a corduroy ocean. Countless swells were marching in lines toward the beach, and the wind was blowing offshore. Probably going to be good surfing conditions, but I was just far enough from home that I didn't want to turn back and get my camera. 

I could see the ocean pretty much the whole way as I walked down Noriega Street, but when I finally got to the beach I knew I was going to have to come back with a camera. I watched for a little while, then walked back home and returned on my bike with the FZ80.

Cam Check

 

Morning Skyline

Since I placed my trail cams in a new location last week, I wanted to get up there to see how they were doing. Sometimes a spot looks like it has potential but turns out to have one of the worst kinds of problems: too many activations caused by vegetation blowing in the wind. Another time I had a location that had zero activations in a week -- no animals whatsoever, not even a bird or butterfly. The worst though, was a location that captured nothing but dragonflies and thousands of wind-activations. 

Usually a wind-activation is the result of something in front of the camera, anything from a plant you didn't notice (or that blew into the frame after setting up the cam), to bushes that seemed innocuous when you set up the cam on a day with little or no wind, but which tossed like crazy later on and set off a couple thousand "empty" frames.

When I got my SD cards home and saw that one cam had 591 captures, and the other had 2,118, I knew right off that I had a wind problem -- although neither involved movement in front of the camera. Instead, both were caused by movement of the tree I'd mounted the cams on. Although it was somewhat tedious to sort through all those frames, I at least got some decent captures (video below).

Because of recent issues with my bike tires (my new pump and innertubes have arrived, but my new tires won't come till Monday) I didn't feel comfortable riding all the way to Mt. Tam, which is how I usually prefer to get up there for cam-checks. Since I was driving the car I figured I might as well bring my DSLR and poke around the mountain a little bit. My first stop was to check out a large patch of calla lilies, but only a few were in bloom. I continued out that trail a little bit in the hope of spotting a hunting bobcat, but no luck there. 

I continued up to Rock Spring and hiked down the Cataract Trail a ways to look for calypso orchids and fetid adder's tongue. I didn't see orchids in any of the usual locations, but I was glad to see that the fetid adder's tongue was still in bloom. It's still early for the orchids, which often bloom into April. In the past I've found them as early as February 20. That was 2016, and this year is no 2016, flowerwise. The forest seemed quite dry.

Point Reyes Medley

 

Sunrise Over Tomales Bay

There's an interesting article on the Science News website about something like the "butterfly effect," where the drought in one part of the world affects the climate on distant continents. The connections they talk about are another reminder of how small and finite our planet looks from the atmospheric point of view.

Most of the photos in this medley, all shot in February, came from a yearlong project I did at Point Reyes in 2015. Sometimes I think about taking that up again, but there's some inertia involved with re-starting a project that feels like it ran its course. What it's going to take is finding a new way to look at it that fires up the needed inspiration.

Ship Spotting

 

The Panama-flagged Cargo Ship Ken Ei, Bound for Sacramento

When I biked home from Mt. Tam the last time (see the bottom of this post) I enjoyed watching a large ocean vessel as it cruised under the Golden Gate Bridge, although I was a little disappointed to learn it was just a tanker ship and not a research vessel (talk about confirmation bias, or seeing what you want to see; it didn't even almost look like a research vessel). I learned what it was by looking it up on -- what else? -- Vessel Finder. The only reason I knew that such a thing existed is because an artist friend got interested in ships several years ago and made a few excellent paintings.

Anyway, when I looked up the tanker vessel I noticed it didn't have any pictures showing it from above. The photos they had on Vessel Finder were all side views from sea level. I figured it might be fun to add some "aerial" ship photos to their web site so people could see the deck. So on Sunday morning I decided to pack my FZ80 and bike over to the bridge. I hit a minor setback when I found that my rear tire had gone flat overnight. The tiny sharp stone that punctured the innertube looked so harmless, especially compared with a couple other things that have given me flats recently (two of which I've saved in my patch kit). I often just replace the whole tube, but I was feeling frugal that morning and decided to patch it, and I was soon off and rolling.

As I approached the bridge I realized I would be on the west-facing side since that's where bikes go on the weekends, with pedestrians having full use of the city-facing side. A ship had just emerged from an offshore fog bank and was steaming for the bridge just as I got there. I didn't realize how lucky that was until later, when no other ships appeared. 

I was glad I'd over-dressed for warmth because there was a chilly wind blowing in. I found a good viewpoint on the north end of the bridge where I could see incoming vessels as well as any that might be coming from the east and heading back out to sea. I don't know if it was a Sunday thing, but no commercial vessels were out and about. 

I was glad to see some San Francisco wallflower (Erysimum franciscanum) growing on the chert cliffs next to the bridge, but I eventually gave up on seeing anymore ships that morning and headed home through Sea Cliff with a stop at China Beach, then found a path behind the Legion of Honor Museum that took me along the coast to Land's End.

On the way home via Ocean Beach and Golden Gate Park I was riding past Stow Lake when my rear tire blew. Arrgh! Two flats in one day. At least it didn't blow while I was cornering, since I'd likely have crashed. I wondered if my patch had come undone, but I soon had the tube out and was shocked to see that it had basically exploded. The patch was solid, but the tube itself must have been made of some kind of super-cheap rubber. I had a spare tube of the same brand, Serfas, so I installed it and put my wheel back on, only to find out the Serfas mini bike pump I'd recent bought with the tubes wouldn't work! My back-up was a CO2 cartridge inflator, and that too either malfunctioned or just had very little compressed air in the brand new cartridge, but I at least got about 10 pounds of air in the tire, enough to get home. 

I felt that I couldn't really trust the bike shop that sold me those crappy tubes and pump, so I ordered quality replacements, including new tires, online. I'd like to have gone to a local shop, but the ebike shop I bought my bike from (Motostrano) went out of business. My local bike shop just down the street (Everybody Bikes) closed during the pandemic. And another local bike shop I've used (Nomad) closed a few months ago when its owner passed away.

Anyway, I look forward to photographing more ships from the Golden Gate Bridge as soon as I get the new bike parts. Even if no ships come in, it's still a nice ride.

[UPDATE] Check out this link I just got from my brother-in-law about a photographer named Jake Ricker who has been doing a street photography project on the Golden Gate Bridge for several years.

Burrowing Things

 

Burrowing Owl at Cesar Chavez Park, February 2011

The oldest form of life on Earth has survived all the great extinction events and is an important part of not just "the ecosystem," but even of the internal microbiome of the likes of owls and humans. Bacteria have ruled the planet for around 3.5 billion years, and all us plants, fungi, and animals had to emerge and evolve in their royal presence. "[T]he cell biology and genomes of all modern eukaryotes were built on a bacterial foundation."

An evolution in bacteria was responsible for the Earth's first great extinction event, which doesn't even count in the so-called five great extinctions, and which made life possible for us eukaryotes. Interestingly, the five extinctions that do count were all a result of rapid climate changes that involved either planetary cooling or warming. 

The earliest of the big five occurred 444 million years ago. But that first pre-big-5 extinction occurred around 2.5 billion years ago and is known as the Great Oxidation Event. It was brought on by the proliferation of photosynthesizing cyanobacteria that produced a deadly gas: oxygen. The bacteria that had been basking blissfully in a warm methane atmosphere for a billion years were unceremoniously torched by this new, highly reactive gas.

As I was thinking about all this it occurred to me that our own ancestral gut microbiomes, most of which are composed of obligate anaerobic bacteria, are pretty good sanctuaries from inflammatory oxygen. Somehow the anaerobes that survived the deadly new Oxygen World burrowed into whatever new forms of life came along that could take advantage of oxygen's power. Now here we are, with each milliliter of our large intestines providing a home to 100 billion microbes of perhaps 400 species.

All us animals, including birds, live with symbiotic microorganisms in our guts, where the tiny critters provide "a multitude of nutritional, defensive, and developmental functions with a myriad of implications for host health and fitness." 

We are dependent on minerals and gases, on liquid water, on microorganisms, and on the plants and animals we consume to power our lives. If you think about it, we truly are one with everything.

Virga Bow

 

Virga Bow at Sundown

The last couple of times I've gone over to Grandview Park to look for a rainbow, all I got was rained on. It's only at unexpected times that I actually see one, including this "virga bow" I stumbled upon when I looked out my rear, east-facing, window shortly before sundown yesterday. Although I'd been somewhat rained on during a bike ride earlier in the day, it appeared that no rain was actually reaching the ground when this bow appeared. 

There wasn't enough daylight left to run a timelapse, and I only fired off four frames before the sunset color drained out of the clouds and the bow broke up.

Since I'm already posting something, I might as well toss in a few phone snaps I shot during my walk and bike ride yesterday. My daily walk down Noriega Street takes me right past the scene of the 22nd Avenue house explosion, which happened the day I biked to Mt. Tam. It happened right around the time of morning that I'm usually walking by there. People heard or felt the blast from many blocks around.

Big Buck Passing Through

I figured it was fairly well established that this location has lots of deer and turkeys, so I moved the cams to a new location yesterday. I locked my bike to a tree and hustled up the ravine, only to soon realize I was in the wrong place. It looked like a pretty good alternative location, though, and I will keep it in mind for the future. 

In the meantime I wanted to find someplace a little different, and one of the new spots I found seemed promising, with lots of bobcat scat around. As usual I would be extremely surprised if any humans showed up in either of the new spots, but I was not surprised to find someone's long-lost Aerobie Ring Flyer. You can chuck those things a mile (well, not quite a mile).

On the way home I saw this gigantic, brand-new-looking ship passing under the Golden Gate Bridge, so I pulled over and grabbed my phone to get a selfie with it. I took note of the ship's name on the stern but mis-remembered it. I thought it was Polar Explorer. It seemed so new, I thought it was one of those NOAA research vessels that sometimes tie up behind the Exploratorium. However, this ship seemed headed toward the Richmond refineries. Sure enough, I took note of the Chevron logo on the superstructure once I got home and saw the photo. It's actually an oil tanker, the Polar Voyager. It looks so spanking new because it was built in 2014.
