Backyard Beauties

 

Hummingbird Attractor

I didn't get out much today due to the smoke hazard, but I did watch the cherry-headed conures in my neighbor's oak tree for a while, and while I was back there I figured why not set up a couple more macro shots in my living room using backyard flowers. It's not like I have to get back to work or anything.








Some of the parrots were strolling around the tree branches and pulling off acorns and whatnot (I could hear all kinds of stuff falling from the tree into the leaf litter, but couldn't see what any of it was). Meanwhile several of the other parrots were paired up to groom each other.


An immature parrot picked up some lichen but didn't appear to eat it, then a little farther along the branch it picked up a stick. Unfortunately, it then turned its back to me and no doubt did something fascinating with the stick, like use it to preen its breast feathers, or just chomp on it like Edward G. Robinson with a cigar.

Grandview Park

 

View toward downtown San Francisco with faded lizard tail flowers sprawled along Grandview Park's fence line.

My chores done for the day, I walked over to Grandview Park to get a little nature fix. The sky was a mix of sun and low clouds, and it was warm enough to be in shorts and a t-shirt despite a ballcap-stealing wind coming in off the ocean. I brought the FZ80 along just in case something called out to me, and it didn't take long to hear the siren song. Just half-way up the stairs I was struck by a low-slung, probably wind-pruned, female coyote brush (Baccharis pilularis) heavily frosted with white seeds.

After that I was on the lookout for other potential subjects and snapped some photos of lizard tail (Eriophyllum staechadifolium) and coast goldenrod (Solidago spathulata). The goldenrod had numerous west coast lady butterflies (Vanessa annabella) and common drone flies (Eristalis tenax), as well as bumblebees (moving too fast for me to get a decent photo), feasting on its nectar.

Looking out toward the bay I saw a container ship, the CMA CGM Hermes, which I thought was kind of a cool name since just yesterday I saw an excellent play narrated by Hermes, called Hadestown.

After shooting the plants and insects with the FZ80 I still felt like doing more photography, so I collected a smidgen of plant material to try some 1:1 macro photography back at home. The focus stacks ran from 21 frames to 38 frames, so I could never have done them in the field with all that wind (not to mention all the people and dogs). Even at home I had to contend with changing window light due to the mix of sun and clouds, but now that I've got my indoor set-up pretty dialed in, I'd like to do more 1:1 stuff. It's always interesting to see details with the camera that my naked eye couldn't make out.

Destination, The Journey

A pair of acorn woodpeckers performs maintenance on their pantry holes.

The destination for my ride was Mt. Tam, where I wanted to check up on a third trail camera I set up last week on a somewhat rickety foundation. Although my mind was making a beeline to the cam, my body reminded me to enjoy the journey. 

In the Presidio I rode past a bunch of fallen eucalyptus leaves floating in a puddle of fog-drip created by their own trees. Ordinarily I'd have kept on going, but I figured "what's the rush," and went back to snap a picture.

Because I make the trip fairly often I don't always feel like stopping along the way to record my sightings in pictures, but it feels good to open that door once in a while. I stopped next to watch a handful of brown pelicans dive into Richardson Bay, but they were too far away to photograph. Nearby, a group of shorebirds was foraging on a little bump of marshland that juts into the bay, a flock of maybe twenty greater yellowlegs.

Later I stopped to watch some black-necked stilts in their usual pools along Coyote Creek, then pedaled up the fog-drippy Shoreline Highway and into the thick of the fog billowing over the ridge along Panoramic Highway. There was sun and fog near Pantoll Campground, but the conditions weren't producing crepuscular rays the way they did last week. 

By the time I reached Mountain Home Inn I was surprised to see that I still had four of five bars left on my e-bike battery. I've been riding in "battery off" mode on flat sections and downhills, plus I'd just inflated my tires before leaving home, but I was still surprised. By the time I'd gone all the way up to Rock Spring and part of the way out West Ridgecrest, though, I was down to two bars. Clearly, each bar does not represent twenty percent of the battery's juice. Anyway, I carry a spare battery for the ride home.

I was glad to find that the trail camera I'd lashed to a somewhat rickety branch was still standing. I'd prepared myself to find it in a heap on the ground, perhaps even blown over by a strong wind. What I didn't find out until I got the memory card home was that it even survived having a gray squirrel pounce on it. 

Almost all the best captures came from that cam, which I set up in a ravine where my other cams had previously caught a descending bobcat. Naturally, the bobcat this time ascended the ravine, so we never see its face. Better luck next week.

I managed to find a fogbow along a steep flank of Mt. Tam, but the conditions never gelled enough to create a brocken specter


It's been a long time since I enjoyed making fire sticks, and as I was recently clearing out some old stuff I don't use anymore I decided to place a few of my hearths and spindles in secret spots within the Rock Spring picnic area, hopefully to be found by someone who takes an interest in them. 


Both the hearth and spindles are made from buckeye wood I collected not too far away (but many years ago). These can be used to make a bow-drill fire, but you'd still need a couple other items to get there. I guess it should come as no surprise that you can actually buy a bow-drill kit on Amazon, but to make your own kit and actually get fire with it is a wonderful experience. I learned this and many other interesting ways to appreciate nature at Tom Brown's Tracker School and Headwaters Outdoor School.


The woodpeckers appeared to be pecking at existing holes in the acorn granary, or pantry, possibly allowing them to more easily accommodate the big acorns maturing on nearby oaks and tanoaks.

The tide was high as I headed home, and the black-necked stilts of the Coyote Creek marsh had gathered together for siesta.


Meanwhile, the snowy egret was still hunting, swishing its front foot in the mud in the hope of spooking prey into showing themselves.

Garden Finds

 

Puffballs & Yerba Buena

When I spotted the Lycoperdon in the garden late yesterday afternoon I was too tired to photograph it (but not to pour a little water on it), and I almost had the same issue today. I'm so used to being most active in the morning that I need to find a second wind to do anything more strenuous than reading a book in the afternoon. 

The puffballs had sprouted in the midst of some yerba buena I recently got from Bay Natives, so I included a sprig of the deliciously scented leaves along with the sandy, loamy soil from which the fungi are growing. I replaced the fungi along with the lump of soil back where it came from when I was done shooting it, and I hope the puffballs keep growing long enough to sporulate.


The original lump of soil included a tiny sprout of Oxalis, my ubiquitous nemesis.


I like these little spurred purple guys, but I've forgotten what they're called. I'm glad I planted them in a pot because they are prolific spreaders.


Besides having very little working space to set up a tripod for shooting in the garden itself, if Coco wakes up from her bed of leaves and sees me, I will have no chance to work without her furry, purry interruptions.

I was sad to learn today that a blogger I've followed for years recently passed away. John was traveling around the country in his RV with his cat Sinbad when I first started reading his blog, then another cat named Beans after Sinbad died. I always appreciated the experience of vicarious wanderlust during the years leading up to my own recent retirement. Unfortunately, John's wife took down the blog after a spate of nasty trolling in the comment section following his death. It looks like his free e-books still survive, at least for now.

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.

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

 

Fuchsia photographed at 1:1 (full frame).
(Click to view larger.)

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.


Crop showing the area I wanted sharp.


A little tighter crop.

The set-up with 105mm and a hazel leaf for the background 
(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.
