Late Summer Fog

 

View of Mt. Diablo from Mt. Tamalpais

When I checked the Mt. Tam web cams yesterday morning, the view east showed a beautiful orange sunrise glow on the tops of an endless layer of clouds. No mountains, no city in the distance. Even the usual foreground near East Peak was gone. There's a similar scene this morning, with the difference that now I can see beneath the clouds, and what I see is a ship in what appears to be the ocean (but might be the bay). Strange that a fire camera would be trained on sea and fog, but maybe it was accidentally bumped out of its usual position.

I hadn't really planned to ride up there since I just checked the trail cams a week ago, but I wanted to add a third camera and didn't feel like waiting the usual two or three weeks before getting it in place. This was my first ride up since tourist season unofficially closed on Labor Day. Pedestrian traffic on the Golden Gate Bridge was much less crowded than a week ago, but automobile traffic and its attendant stink of exhaust fumes was about the same. 

A couple of brown pelicans were diving for fish in Richardson Bay, and black-necked stilts were back in the marshy area around Coyote Creek. I finally reached the sun/fog interface between the Bootjack and Pantoll parking lots. When I got into the woods, the fog had made the leaves less crunchy than they were just a week ago. The nagging horse flies seem to have disappeared, and the sun was nice and warm without being too hot. The autumnal equinox is just two weeks away.

The other day I noticed a flock of parrots (cherry-headed conures) in my neighbor's oak tree. All of the parrots appeared to be resting, preening, and socializing, except for one of them that was busily hunting for acorns, which it appeared to be eating. I've mentioned this before to my neighbor, and he believes they are just playing with the nuts, not actually ingesting them. Although I am prepared to entertain that possibility, it sure looks like they are eating the nuts (video below).

Here's the PM view....

The bobcat must have been moving fast. The camera was set to capture three still frames, then a 10-second video, but the bobcat was already gone by the time the second still shot fired.

A cherry-headed conure, one of "The Wild Parrots of San Francisco", uses its strong beak and agile tongue to munch an acorn.


Here's a short video clip of the parrot (shot through a double-pane window). Is it eating the acorn, or just playing with it?

Fuchsia Close-up

It was a dank and foggy morning in my neighborhood yesterday and I was feeling too lazy to go for my customary long walk, so I decided to test an old 200mm Micro-Nikkor AI-S lens that I've kept stowed away for many years. I'd originally paired this lens with a Nikon F3 but stopped using it when I bought a D800 (could it really be almost 10 years ago?!) because I thought it wasn't sharp enough. 

That idea was based on a close-up photo I'd made of some goldfields on Mt. Tamalpais. I kind of liked the soft-focus look for that subject, but I felt such a soft lens wouldn't do once I had a 36 megapixel camera.

At first I thought I'd do the test out back, where the fuchsia flowers are, but I decided to bring one of the blossoms indoors to do it right, using a tripod. I compared the 200mm with a 105mm AF Micro Nikkor that I use all the time. The 200mm only goes to 1:2, so I set the 105mm likewise, and shot a single frame at f/16, using a flash.

The result was a great reminder that the fault for a soft image is probably technique, not equipment. Maybe those goldfields jiggled in a slight breeze that I didn't detect. Maybe I didn't set the focus point in just the right place for the aperture I used. In any case, the 200mm image looked sharp. The lens was not the problem.

Since I had the fuchsia indoors anyway, I took a few shots of it with the 105mm at 1:1. I set the camera on a focusing rail so I could make focus stacks. This is old school stuff, where I have to  manually turn a knob to adjust the camera position. 

My first two tries on the fuchsia were sharp, but not throughout the whole subject area I wanted. Despite shooting at f/16, I couldn't get what I wanted until I barely turned the knob at all between each frame. It was as if the depth of field covered no more than half the diameter of the little white pollen sacs. The bonus was having the gnat on the stigma remain motionless during the time it took me to adjust the focusing rail through 17 frames, letting the flash recycle after each one.

A little tighter crop.

(I held the flash at a higher angle for the shots).


After shooting the fuchsia I tossed the hazel leaves into the back yard. When I went down there hours later and saw how the mist had settled on one of the leaves I couldn't resist making another macro. I've always been fascinated by nature's intricate beauty, from the atomic to the galactic.

August Camera Trap

 

Bobcat on the Trail

Last time I was up there I relocated one of the two cams to what turned out to be a pretty good spot (the scene above). The other cam did okay too, but it tends to capture animals farther away than I like, so yesterday I moved it, too. Being able to review the captures on my phone by way of a card-reader dongle is a handy way to make placement decisions while I'm on the scene instead of back at home.

Begonia & Berries

 

Backyard Begonia With Twisty Anthers

We were amazed to part the curtains and see a fog-free view this morning. It smelled a little bit smoky, apparently due to the wildfires up north, but a regular sunny day seems almost like some kind of natural wonder after many days of fog.

I found a surprise in the back yard yesterday, a couple of broken branches on the huckleberry plant, and wondered at first if it had anything to do with the family of five raccoons who've been rooting around back there lately. But I think it's more likely that the branches simply broke due to the weight of ripening berries which were mostly congregated at the ends of the branches. 

In the 15 or so years I've had it back there I've never gotten such a big harvest. I collected what berries I could, although many fell to the ground. Surprisingly, none of the local raccoons, squirrels, rats, or birds seem interested in them. I put a heap of them in my oatmeal this morning, and they were excellent.

More Yardage

 

Selfheal (Prunella vulgaris)

Selfheal is another one of those plants, like the orchids, that came into our garden on its own. I confess a fondness for it because it reminds me of the couple of years I lived in Arcata, where I first saw it, a common but pretty yard weed. 

Until I took these pictures at a 1:1 magnification ratio, I hadn't realized they were so hairy. We have lots of selfheal in a rectangular patch in our yard (I have to hold the line on its spread into unwanted areas), but this was the only one currently flowering. I was reluctant to cut it when I leaned down with my scissors and saw a hoverfly probing the blossoms. But one thing's for sure about hardy Prunella, there will be plenty more flowers.

Hope It's Not Hella Boring

 

Helleborine Orchid

I wanted someplace to post random phone snaps from neighborhood walks and that kind of thing, so I created an account on Instagram for them. Check 'em out at https://www.instagram.com/jwallphoto.sf/. [UPDATE: It's now 4/20/2024, and I almost never post anything on Instagram.]

The orchids above and below are actually "weeds" from our little garden. I didn't know what they were when I first saw them growing a couple of years ago. We certainly didn't plant them, at least not on purpose, so I cut them down even though I suspected they might be related to the Epipactis helleborine orchids I've seen on Mt. Tamalpais this time of year. I'm told it's the only naturalized orchid in California. All the other ones we find in the wild are natives. Anyway, this year I decided to let them flower.

Since my computer is still so new I can't help waxing a little enthusiastic about how fast it is. The specs don't seem that different from my old one, but all of a sudden Lightroom and Photoshop open right away, and Helicon Focus blazes through a 17-image focus stack of raw NEF files. I'm impressed.

Shape-shifting

 

An immature acorn woodpecker (given away by its begging) crowds an adult as the adult removes a saved morsel from an acorn pantry on Mt. Tamalpais.

I recently replaced my seven-year-old computer because it would no longer connect to the internet. It seemed like a bit of a shame to get a whole new box since I could still use apps like Photoshop, but now that I've gotten everything set up (always a bit of a headache), I'm impressed by how fast the new machine is. It boots up in about a minute, versus the old one's 10-15 minutes! I used to turn on my computer, then go make breakfast and coffee while it booted up.

It seems like I just got back from reveling in the mountain air among the bristlecone pines, but I'm already yearning to make another trip. The tropical storm that just passed through makes the prospect even more enticing, as does next week's blue moon (the second full moon in August).

In the meantime I biked up to Mt. Tam to check on the trail cams. They didn't get as much action as I'd hoped for during the last two weeks. I probably wouldn't even have posted anything on the blog, but the video had a nice surprise in it, with a buck deer shape-shifting into a coyote. 

Also, in homage to the tropical storm, I've posted some old rain-in-the-city file photos.


The adult prepares to launch, taking its acorn to a quieter location.


This animal trail is much steeper than it looks, and the coyotes, deer, and foxes, all negotiated it much more gracefully than I did.
