Crucial update

Sneaking this in before it becomes tomorrow, but I had to check and see if our new little friend had taken up a sleeping spot nearby, and indeed it had:

newborn Carolina anole Anolis carolinensis sleeping upright on hosta seed pods
These are the seeds of one of the two hosta plants that our newborn Carolina anole (Anolis carolinensis) was skipping around on this morning. In the afternoon we got another horrendous downpour (I’m not complaining,) and I figured the anole would have gone for deep cover, but apparently the call of the hosta was too strong. And now The Girlfriend and The Girlfriend’s Sprog both got to see it too, so we’re all good.

Well, now…

newborn Carolina anole Anolis carolinensis peering around hosta plant
Had to feature a sudden find late this morning – if this guy had held still, I would have easily missed it, especially since I’d about given up on seeing one this year. This is a newborn Carolina anole (Anolis carolinensis,) scampering around on one of the hosta plants, appearing at a time when even the adults could barely be found. This might have come about because we had some heavy rains in the past day and the temperature finally dropped to, “Not Deadly,” but I wasted no time in trying to get a selection of pics, including some scale shots. Afterwards, I measured the stem that the anole is clutching, and it’s 5mm in thickness; the twig off to the right is actually just some pine needles. Though we can do even better than this.

Not only did it let me get away with slowly sliding my fingers close to it, for a moment it looked like it was about to jump onto them, then appeared to reconsider that idea. This is in a line along the front walk that has two gardenias (one of which is seen here, the roundish leaves,) two hostas, and two butterfly bushes – in other words, happy hunting grounds for little anoles, and they’ve used it as such all last summer. It’s great to see one doing so again.

Now, I say “newborn,” but I honestly don’t know how new; I suspect that they remain sequestered in leaves for a while after hatching, but they’re largely independent and the mother doesn’t feed them at all. According to Wikipedia, egg development in the mother takes two to four weeks, and incubation after laying from five to seven, so we’re within the scheduled period – maybe a little later if this one was close to laying eggs, but that pic was around the back of Walkabout Estates fairly distant from the newborn, so not likely the same clutch. Overall length is roughly 55-60mm – not far from newborn, at least.

But we need a better look at that detail.

It looks like it’s napping here, and might well be – I’ve seen the behavior countless times, where right in the middle of scampering around in their slightly manic way, they pause and simply close their eyes, even when they know I’m nearby. It only lasts for a few seconds and I have no idea of the purpose – maybe it’s an attempt to Force Hurl me away. Still, look at that wonderfully textured skin.

I may dribble a few drops of the hummingbird food on the leaves near here to attract the ants, because that’s what these guys like to eat, among other things. I do what I can for my subjects.

Scattered, the start

I have a collection of semi-recent but unrelated images in the blog folder awaiting my attention, either to include them in a post or simply discard them as irrelevant, and so I decided that I’d do posts around a single image, partially because I haven’t been posting much and this is easier. Somewhere in there will sneak in a couple of longish, philosophical posts as I get motivated to tackle them, but for now we have these.

image of sun with solar filter showing sunspots and hints of clouds at edges
This one I’m faintly annoyed with myself over. Not because of the image itself, which is not bad for an initial experiment, but because I didn’t do the experiment sooner. It is the sun of course, through the solar filter material that I purchased specifically for the total solar eclipse in April. The material was/is flimsy mylar film however, and to keep it in good shape I sandwiched it between two pieces of picture frame glass and made a holder to go onto the lenshood of the Tamron 150-600 to keep them all in place. The results were terrible, and while I did a few frames during the eclipse, to say that they’re unremarkable is vastly understating it.

Then recently, I created a new holder that simply clamped the edges of the filter but otherwise left it alone ahead of the lens, and got this result. Well, shit – that would have been nice to have during the eclipse, right? And I kick myself for not trying it before now – in fact, I’m wondering how the experiment escaped me, because I was suspicious of the quality of the glass even back then.

But I also recall that I was ass-deep in the tracking motor project, concentrating on getting some esoteric images during totality, and that this dragged on with issue after issue right up until the day before the eclipse, when I finally gave it up. I had rebuilt the platform, re-printed several parts, tried umpteen different variations of the motor driving software, re-ordered another motor and a driver for that, fretted through interminable and pointless postal delays, switched software, and so on. It was obsessive, and truth be told, I wasn’t really fired up to get images of the partially eclipsed sun as much as what totality might allow.

Still, damn, should have at least tried a quick experiment.

By the way, those are indeed sunspots, with perhaps a hint of clouds around the edges – I was timing the sun between appearances of scattered clouds and may have caught the vestiges of some, which I wouldn’t have been able to see in the glare. That one spot in the middle is so distinct and round that I wondered if I didn’t catch Mercury in front of the sun, but no, Stellarium told me it was well off to the side. And just so you know, I’ve been trying to reprint a better filter holder, but my 3D printer is being balky for as-yet unknown reasons, and other projects have prevented me from troubleshooting this right now. I know you need this minutia to feel complete…

Just once, part 29

long-billed dowitcher Limnodromus scolopaceus wading
I was a little surprised to find that I’d only ever featured a long-billed dowitcher (Limnodromus scolopaceus) once before, because I was certain that I’d gotten other images of the species – and I had, even featured here before. Kind of. Here’s how it works.

The source that I’m using to find the ‘Just Once’ candidates is a dump from the database of tags that only appeared once before, just like the tag roundup at the beginning of each year. So they’ve only appeared once when identified by name. However, not only do they appear in the rotating banner at the top of the page, another frame from that same session was edited to use as a page break where needed, like so:


Curiously, this was discovered when I started this post and searched on “dowitcher” in the library of uploaded images for that photo above, finding two other hits – both the page break images, which then reminded me of the banner image. So yeah, they’ve been seen before, but not specifically named at the time.

The one at top was taken in Huntington Beach State Park in South Carolina, five years ago (doesn’t seem that long to me, damn.) The others were all from Sanibel Island in Florida, like fifteen years ago – which was the last time we’d been to Florida, something that I keep vowing to correct and yet still haven’t. And it won’t be this year either, not even if someone funds it.

These are not snakes

green treefrog Dryophytes cinereus calling among pond reeds
No, I’m not trying to show off my amateur naturalist cred, and no, ‘amateur naturalist’ doesn’t mean I’m bad at getting nekkid – that’s ‘naturist,’ goober. And you still wouldn’t want to see it.

No, I’m referring to the fact that all of these were shot while I was looking for snakes for World Snake Day, which is still going on as I type this and might, just might, see some late entries. I was just seeing a lot more than snakes, like, the green treefrogs (Dryophytes cinereus) were remarkably active last night, possibly because it had cooled down a little more than it had been. This did not make it ‘cool’ – I was still covered in sweat from the session without any physical exertion and only a tiny bit of stress, but we’ll get to that.

pair of green treefrogs Dryophytes cinereus, one calling, on pond reeds
None of the snakes that I saw were anywhere near the spots where the frogs were, which suggests that snakes would do better if they could hear, because these guys were hard to miss. But hearing takes place in most animals through the repurposing of jawbones from our ancient reptilian ancestors, the same bones that snakes kept in their jaws to allow them to swallow prey much bigger than their head. Now, snakes are pretty sensitive to vibrations felt through the ground (or anything else they’re sitting on,) and I spooked one of my potential subjects by carelessly trodding softly on a pinecone that was over a meter off – the snake’s immediate reaction would’ve convinced you that they could hear. But a day of heavy rains wasn’t enough to counteract six weeks or more of scalding sun, and so the earth remains dry and packed and may well have carried the vibrations better. Or the pinecone was wired into the snake’s vibrating cellphone. Meanwhile, I wonder if frogs have developed calls in a frequency that doesn’t elicit many vibrations where snakes can sense them, because they certainly were louder than the noise from the pinecone.

small green frog Lithobates clamitans sitting near pond edge
This was one of several other species out last night, a green frog (Lithobates clamitans,) a larger and aquatic frog, though this specimen was only fractionally bigger than the treefrogs. These were calling too, as were American bullfrogs, eastern narrowmouth toads, and some ‘ratcheting’ bugger that I didn’t recognize by sound and couldn’t get a peek at. Yep, one big singles bar of attempted procreation, and me voyeuring in the middle of it.

trio of green treefrogs Dryophytes cinereus on pond reeds
I think these were the same frogs and reeds seen above, now on my return pass, and I’m pretty sure another was calling just out of sight behind these reeds, suggesting that these were all ardent males. I’d sit and video the process but I’m not sure that I’d see much, because the light of the headlamp (and by extension the video light) makes them nervous and tend to stop calling. Plus in reeds like this, it’s easy to get a bad light angle and throw shadows, which makes them even more nervous because something blocking out the sun is often an indication of danger looming.

pair of green treefrogs Dryophytes cinereus in amplexus
However, I did at least find a pair that had almost sealed the deal, yet still sitting complacently on a trunk instead of heading down to the water to lay and fertilize some eggs. I’ve seen this plenty of times – there is often a period of just sitting there, and I don’t know why this is – possibly that ‘small talk‘ thing I keep hearing about.

By the way, if you noticed that the female’s eye doesn’t have the distinct reflection of the male’s, this was even visible in the headlamp while I was focusing, and is potentially a damaged cornea.

There were more than frogs out too. Like spiders.

large fishing spider possibly Dolomedes tenebrosus standing more upright on log
There were scads of fishing spiders all over the place, skating out across the water, but all of those that I could see clearly were smaller examples of the six-spotted fishing spider. This, however, was many times their size, curiously standing ‘tiptoe’ on a log out in the water, so I couldn’t get closer. It’s likely a Dolomedes tenebrosus, the largest species of fishing spider in this area, whose leg spread can cover your palm. Why it’s sitting like this I can’t say, but it does remind me of how I stand sometimes when it’s too hot and those sweaty areas are getting annoying.

possible rabid wolf spider Rabidosa rabida hunting on weeds
According to a quick search just now, this would appear to be a rabid wolf spider (Rabidosa rabida) – the markings fit the description and the photos. What got my attention were brilliant and largish reflections from the eyes; I’d been seeing such all night, because both wolf and fishing spider eyes reflect vividly and they were all over the place, but these were brighter and more distinctive than I’d seen before and I went in for a closer look. She didn’t want to come out in the open and this was as good as I could coax her to pose, but she almost got a free meal from me because the moths were attracted to the headlamp and they kept blundering into her eyrie – she made a couple of failed attempts to catch them as I watched.

The other was a lot more cooperative, however.

unidentified female wolf spider Lycosidae with brood on her back
This one was large enough and dark enough to be found without any help from reflections, which was a shame because there should have been a lot of them. Too few markings visible to try to identify, plus the fact that many wolf spiders (Family Lycosidae) are difficult to distinguish anyway, but it’s clearly a mama wolf spider with bebbies. Note the rearmost row of eyes, the position of which distinguishes this from fishing spiders, where they would be more in a row with the two largest eyes. And of course a few bebbies moving forward onto her cephalothoraz. She paused and held still nicely for several close frames, and even allowed me to sneak my finger into the frame on the smutphone for a scale shot to freak out friends – in leg spread she was probably close to 60mm.

And even more – not spiders, but we’re also not reducing the leg count.

likely red swamp crayfish Procambarus clarkii foraging just out of water of pond
I’ve seen these from time to time, most often after a heavy rain which tends to bring them out onto land. I believe this is a red swamp crayfish (Procambarus clarkii,) quite large as far as crayfish go, not just rivaling shrimp, but they also used to form the bulk of the crayfish served as food – this one was over 100mm in length, snout to tail, and much thicker than my thumb.

likely red swamp crayfish Procambarus clarkii, male, foraging out of water from pond
Those larger chelae (pincers) indicate this is a male, and it was foraging enthusiastically in the mud at the water’s edge, almost wholly exposed from the water. Those eyes were producing red internal reflections which showed up well in the headlamp, only vaguely visible here (the flash was offset a bit.) Eventually, I did an incautious move that alerted the crayfish somehow, because after several frames and a little maneuvering from me for a better view, he decided to hurriedly slip back into the water.

And finally,

female eastern bluebird Sialia Sialis watching photographer carefully from bluebird box
Remember what I said about stress? One of the bluebird boxes along the pond was occupied again, the second brood for the year (quite common around here,) and the female eastern bluebird (Sialia sialis) was just watching me, unblinking, unmoving – it was seriously creeping me out. What? I’m just looking for snakes, I don’t give a shit about your eggs – go glare at someone else.

It qualifies

Today, as you undoubtedly know, is World Snake Day, and while you might think this is one of those crass bogus holidays that I make up to feature some convenient photos on hand, this is for realsies. Knowing that this was coming up, I went out to find some world snakes to feature, knowing that at the very least I was in the right geographic area (the world) to do so.

northern water snake Nerodia sipedon sipedon settled on pond edge
This is a northern water snake (Nerodia sipedon sipedon,) and here’s the deal: I was reasonably certain that I’d find at least one example by going over to the neighborhood pond at night, when they’re most active. Not to mention that the days have remained brutally hot and even blog posts aren’t worth the abuse of searching around in the open for any extended period of time during the day. So as the last light was fading from the sky, I ventured over to see if there was any activity – for some reason, foregoing the camera and taking only the smutphone. This meant that I saw three separate snakes on shore, but could get no decent photos of any of them because smutphones suck – I really don’t know why I went without a real camera, but I was thinking I might set up the video rig instead and do it as moving pictures. But since all I’d seen were snakes that were motionless until I got too close, I instead came back with the macro rig (different brackets and lighting,) for my blog images. And that meant that only one of the three had reappeared for the holiday.

northern water snake Nerodia sipedon sipedon showing cloudy eye from being close to shedding
And you see here what might be the reason why. As snakes get close to shedding their skin, they eyes get cloudy and they tend to bask more to help the skin dry out and peel away, and so this one returned to the same spot twice after having been spooked from it by my shenanigans. This was a relatively small specimen, about 1/4 the mass of one of the others that I tried using the shitphone to get pics of, and I could have easily picked it up, but there was no point. First, I’d get bitten exuberantly, because water snakes do that even when they’re not overly defensive from not being able to see through their cloudy eyes well, but this has happened to me many times before and it really isn’t an issue. More, I’d have to be juggling the camera one-handed if I did so, while trying to manually focus by the light of the headlamp because that’s too dim for autofocus. Plus the snake had already been disturbed enough.

I saw plenty of other subjects that were not world snakes last night as well, and they’ll be along soon. But it’s kinda busy today and I wanted to get this out before too much came up and I missed the holiday – you know how important those are to me.

Blink and you missed it

first quarter moon five seconds before occulting Spice
The conditions held and I did get out to watch Spica disappear behind the moon. I tried a short video clip, unable to tell if it was actually capturing Spica or not but suspecting that it wasn’t – the frame rates for video translate to a pretty short shutter speed and even as bright as it was in comparison, Spica was still pretty dim. Upon returning home, I found that I could indeed make out Spica in the video through its scintillation and should have tried it – except that the batteries were running a bit low and video absolutely trashes them, mostly through having the LCD on the back of the camera active constantly, and I was close enough to the event to not want to switch out batteries. All that said, you can see Spica up there as the little speck to the left of the moon, very close to the shadowed portion – as in, about five seconds from it.

Now, I was using mirror lockup as I said, so timing wasn’t really a thing even if I felt (which I didn’t) that my watch was perfectly synchronized to orbital periods and all that. I was waiting about five seconds after locking the mirror up before tripping the shutter to actually snag the picture, so watching for some telltale that it was about to happen wouldn’t work in the slightest. Even without the delay it wouldn’t have worked, because I was watching Spica in the viewfinder to see if I might make out it dimming or something and it simply winked out without warning. So the next frame is five seconds after that:

first quarter moon immediately after occulting Spica
The sudden disappearance didn’t really surprise me, given that nearly all stars are so distant that they’re mere points of light to us no matter what telescope is used, but I’d hoped there might be a hint of something, especially if I could capture it. Nope.

But while we’re here, we’ll take a look at something that I said I might try.

two-frame animation of first quarter moon roughly 150 minutes apart
The first image is the whiter one, taken at roughly 9 PM EDT, while the second is shortly before Spica skipped out, about 150 minutes later. Not only was the moon at a different angle, somehow I’d shortened the zoom down a bit from maximum for the second session and it was shot at 552mm, so I had to tilt and resize them to match – and I’m almost certain you’re seeing evidence of the moon’s libration, the faint wobble that it has as it orbits (watch the distance of the mares from the right side.) You can definitely see the advancement of sunlight along the terminator, as well as the softening of the shadows within some of the craters more towards the center of the sunlit portions. And yes, the color change was that noticeable, even though the moon was quite some distance from the horizon – atmospheric haze and thin clouds were the culprits I believe.

Overall, however, I’ll watch only for planetary occultations, because stars are too boring.

Preliminary

first quarter half moon with Spica showing off to left
Just now, took a peek out there as the sky was darkening, noticed that it was more than clear enough, and did a couple of test shots. I also noticed another speck in the viewfinder and reframed, but I was still working handheld and sharpness was lacking. As I was setting up the tripod and getting the remote release out and the camera set for mirror lockup*, the last little light and color was fading from the sky, but it still allowed me to snag the moon and Spica in the same frame – that’s the star well off to the left. It’ll be closer in a few hours.

I can see a couple of little specks on the terminator of the moon, edges of craters or mountain peaks just catching the hint of the sun over the moon’s horizon. It’ll be interesting to see how much they’ve advanced by the time of occultation – I may have some comparisons then.

*Mirror lockup: the mirror slapping up right before the shutter opens introduces a pretty good amount of vibration into the camera, which can show on the images at high magnification if the shutter speed is low enough, such as for night sky photography. Mirror lockup is an option on many camera bodies, which allows the first press of the shutter release to simply raise the mirror, allowing the vibrations to die down before another press opens the shutter itself – some cameras simply set for two seconds of delay, but in my experience with long lenses, five is much better. It really can make a significant difference.

Watch Spica vanish before your eyes!

Stellarium plot of the occultation of Spica for July 13, 2024
I really haven’t been finding posting material recently, because I’ve had a lot of other things going on, though I have a few unrelated pics that may show up a little later. Right now, I’m providing what little warning I can, having discovered only this morning that the moon will be occulting Spica this evening.

Basic orbital dynamics: the stars move across the sky only because the Earth rotates, but the moon has its own orbit and thus moves slightly differently than the stars, which means from time to time it will block them. Actually, it blocks a lot of them, but it’s often bright enough that we can’t see the stars close to it anyway, so we notice nothing. In this case however, Spica is one of the brighter stars and will disappear against the half-moon’s darker side, at roughly 11:30 PM EDT.

If you’d like to see this for yourself. I’d highly recommend downloading Stellarium (which produced the screenshot above) and getting your location plotted and saved within; this will provide a much more accurate account of when and where it will occur for you (though you can probably figure out where easily enough by watching the moon.) I might endeavor to do this on video if Spica is bright enough to snag at the normal frame rate, which it may not be. But if the skies remain clear, I should have some still photos at least.

Spica will actually re-emerge from the other, sunlit side of the moon roughly 100 minutes later, but it will have set by then at this location. I played around with locations a bit, and determined that from Avon, NC – far out on the Outer Banks – there’s a slim chance that this could be seen just before it dips below the horizon, but this is close to a five hour drive from here and stands a very good chance of being obscured by atmospheric haze anyway, even if the sky is “clear,” so I won’t be making that attempt. Further west in the country, however, the re-emergence should be visible, so give it a shot if you like.
