Your opinion matters

So does your readership, and in fact, your actual existence – is there anyone actually reading? Plowing ahead anyway…

I have two pairs of very similar photos for you to evaluate, and all I’m looking for is which you like best. Not asking about artistic merit, or which shows better details, or whether I should give up photography and go back to, um… something… just which of the pair do you prefer?

The first pair:

osprey Pandion haliaetus soaring next to defocused moon
Do you like this one, or the own immediately afterward, below?

osprey Pandion haliaetus soaring next to defocused moon
An unrelated side note: While the osprey (Pandion haliaetus) was a pretty good distance away, it still wasn’t anywhere near the ‘infinity’ point of the Tamron 150-600, so the moon wasn’t in focus, even at f11. I’m slightly glad that it wasn’t a full moon, since the round fuzzy white spot might simply have been mistaken for an odd reflection or ghost or something, but I wouldn’t get a full moon this high in the sky in daytime anyway.

And the next pair:

juvenile green treefrog Dryophytes cinereus poised to jump
With its companion image:

juvenile green treefrog Dryophytes cinereus poised to jump
All I’m going to say right now is that these were all from yesterday, though obviously spaced a short while apart. I may be back later on with more photos from the day, and to explain my own thoughts, though really, I’m on the fence myself.

Not waiting for Friday

Actually, it’s already waited a few days now, mostly because I either didn’t have the time to post or wasn’t in the blogging mood; since it was this past Friday, it really could have just squeaked in as an ‘Estate Find XXa’ or ‘XX.V’ – did the ancient Romans use decimals? Maybe lower-case Roman numerals, like, ‘XXv?’ Whatever.

Out with the headlamp, because more things happens at night, I was passing through the bamboo and cypress-knee jungle along the north edge of the pond when I got a strong reflection from up ahead, seeming larger than most spiders. It also wasn’t reddish, like the frogs and toads tend to be, or blue-green like the spiders – it was white. I advanced on it, keeping my eye on the spot because, once I get close enough, the increasing angle between the headlamp and my eyes cancels out the reflection. I closed on the spot and couldn’t initially find the culprit, even though I knew it should be right around this medium-brown mossy lump, a moss I hadn’t seen before.

Forest for the trees…

newborn white-tailed deer Odocoileus virginianus fawn in protective bed in grasses
Really, I was focused on finding something about a hundred times smaller, plus the outline of the fawn wasn’t apparent at the angle that I approached from, but yeah, I felt stupid when it all came together. This is of course a white-tailed deer fawn (Odocoileus virginianus,) probably not more than a week old and certainly still in the nursing stage; it was roughly the size of a terrier, perhaps not even two kilos, though I did not pick it up. The reflection that I caught was its eye, and it was well aware of my presence but didn’t move a millimeter.

This perfectly normal: while the fawns are very young, they don’t have a lot of energy, and so they are placed in a safe spot by their mother and simply stay put until mom returns from foraging, which may be hours later. Back in my rehab days, we had to tell people this all the time, because they were always convinced that the fawn was orphaned or abandoned. I can recall the undisguised skepticism on the faces of one young couple as we insisted that they take it back and leave it where they found it, but they did at least return afterwards and apologize, since mama was waiting right there and snorting at them as they brought the fawn back.

I checked this one for dehydration, because occasionally they are orphaned, but it passed easily; this elicited the only movement from the fawn, a faint flinch as I touched the nape of its neck, and that was all. I checked after a couple of hours, and it was still there, so I deposited a cache of corn nearby for the mom, knowing the fawn wouldn’t touch it. By early morning, however, the fawn was gone, though the corn remained untouched (it disappeared by nightfall.)

We’re keeping a close eye out, since eventually the mother may come through with the fawn in tow once it’s eating solid food; we’re still putting down plenty of corn, ostensibly for the ducks, but the squirrels and deer seem to ignore this stipulation, and whatcha gonna do? Worse, however, was that The Girlfriend had gone to bed early and so didn’t get the chance to see this one in person. You should have seen the unbridled delight on her face when she got to hold a fawn a few years ago, about this same size, whose mother had been killed on the highway. She still has those mothering instincts, though that one went to a licensed rehabilitator.

Estate Find XX

This one goes back a little too far, certainly not counting as this past week in any way, but I didn’t want it back-to-back with XIIX. Once again, I was out exploring at night by headlamp, but really, I was standing just outside the front door when I spotted a dark spot in the yard not far from the greenhouse. It was easily identified just by getting a little closer.

adult female yellow-bellied slider Trachemys scripta scripta with excavation for eggs
That’s a female yellow-bellied slider (Trachemys scripta scripta) with an excavation to lay eggs within – I couldn’t see into the cavity to know if there were already eggs deposited, and was trying not to disturb her, but there was no doubt that she knew I was there. Carapace length was somewhere around 20-25cm, and she’s about 35 meters from the closest edge of the pond (all uphill.) I didn’t have to wait long to see something, though.

adult female yellow-bellied slider Trachemys scripta scripta just after depositing egg in nest
I blew my timing by a mere hair here, since the egg has just dropped. I observed for a little while, and noticed that she raised herself to release the egg, then lowered herself back down for a minute or so before the next one was in position to be laid.

adult female yellow-bellied slider Trachemys scripta scripta extruding egg into nest
Better timing on this one – I learn fast. She continued with her duties with no further recognition that I was there – I imagine that there wasn’t anything she could do to halt things at this point anyway.

But, we have video:

I left her alone soon after that, and returned the next day to examine the nest. The only evidence was a couple of faint claw marks where she’d dragged dirt over the excavation, but it wasn’t right where the hole had been dug.

recovered and disguised nest of yellow-bellied slider Trachemys scripta scripta
Using the other photos and the video to compare, the nest hollow is actually at the bottom of this image, slightly left – she’d dragged leaves over top to help disguise it. I put a tomato cage and a couple of plant markers around the perimeter, and noted the date on my calendar, with a reminder at 60 days to begin checking routinely (the inside time for incubation is about 65 days, outside up to 80.) Hopefully, we’ll have another Estate Find around that time, either for her or for the common musk turtle, perhaps both.

To add, we’ve found numerous turtles venturing across the yards in the past couple of weeks, since this is laying season and the pond is absolutely loaded with turtles. In two months, I’m going to have to be very careful when mowing, since the newborns will likely be returning. You may ask, why do the mother turtles wander so far to lay eggs and present a hazard for the babies just to return to the water, but I imagine it has something to do with a) finding spots that maintain the right temperatures, and b) finding spots that won’t get flooded with heavy rains, or at least will drain quickly. This one was easily the highest location on the property; just out of sight is the concrete pad that used to be a small basketball court and is now a greenhouse foundation (because neither of us could give a rat’s ass about basketball.)

Anyway, we’ll see what happens in the coming weeks…

Like a convention of reptiles

Well, not like a convention of reptiles…

First off, this serves as your reminder that Endangered Species Day is Friday, May 23rd (the third Friday in May,) which also falls on World Turtle Day, always the 23rd of May. No cheating and using an endangered turtle to celebrate both in one go, unless you actually can, and then go for it.

captive-bred axolotl Ambystoma mexicanum from Carolina Axolotls at Mid Atlantic Reptile Expo
The example photo here is actually an endangered species, an axolotl (Ambystoma mexicanum,) a neotenic salamander species found in the wild only in three locations near Mexico City, Mexico. However, there is an active captive breeding industry around them, largely because they have the ability to regenerate injuries, including entire limbs, and so they are maintained for lab research, and the exotic pet industry exclusively uses former lab axolotls as their breeding stock. The one seen here is a specimen from Carolina Axolotls, and did not go home with me though I have been waiting to adopt one for a while now.

But that springboards us into the main topic, which is, I spent some time last Saturday at the Mid Atlantic Reptile Expo over in Greenville, responsible for adding to my photo backlog tremendously, which we will alleviate here a bit more.

false water cobra Hydrodynastes gigas at Mid Atlantic Reptile Expo
This is a false water cobra (Hydrodynastes gigas,) a South American native that was not just docile, but quite inquisitive and ‘friendly,’ even though I typically don’t like giving mistaken impressions of species by using such terms. She extended over to greet me without hesitation and had no issues with handling, and indeed tried to shift over onto me – I was fine with it, but it made getting photos a little tricky.

portrait of false water cobra Hydrodynastes gigas with tongue extended
I found out afterward that they do indeed have a weak venom, making it a little surprising to find openly in a crowded convention hall, but they’re a rear-fanged species and it generally takes a protracted, chewing bite for such to inflict venom, and this one wasn’t the least bit inclined – they’re actually considered good pets.

[This was early in my photography efforts for the day and the ISO was still a little too low to ensure sharp pics – they get better after this.]

On the other hand, we had some like this:

Biak green tree python Morelia viridis in warning enclosure at Mid Atlantic Reptile Expo
Green tree pythons (Morelia viridis) are known to be a bit grumpy and not a mellow, easy-to-handle snake, and those from Biak (an island in New Guinea) are reportedly more so – this one was not coming out to play. Unlike another example from the same vendor.

likely emerald tree boa Corallus caninus coming over towards author, Mid Atlantic Reptile Expo
This, I believe, is an emerald tree boa (Corallus caninus,) but I did not confirm this; despite the resemblance, these two are not closely related. Not large as far as emerald tree boas go, the head was only about 25mm in width, and while it posed nicely for the portrait, it was less cooperative in allowing me to snag the tongue extended, ceasing such activity as soon as I was focused. Eventually, through several tries and waving my fingers closer to its face (provoking its curiosity,) I managed to catch it.

likely emerald tree boa Corallus caninus with tongue extended, Mid Atlantic Reptile Expo
I understand why a lot of people find such poses and appearances menacing, but this one was only inquisitive and quite calm, just wanting to explore. Like most species of anything, if they’re not threatened, they’re not defensive, and will behave in placid manners, though temperaments vary from species to species – some will feel threatened easily, or respond more vigorously, but this isn’t meanness or aggression, just how they evolved to handle their environments and risks.

Some are shy.

very shy and protective ball python Python regius nestled in new owner's arms
Ball pythons (Python regius) are perhaps the most common of the exotic snake trade, and indeed there were dozens if not hundreds at the expo. This one had recently been purchased by the holder and was a little overwhelmed with the activity, nestling down and staying protected. I had a ball python for a while, and they really are mellow and easy to handle. But overall, I’ve given up on having snakes as pets, mostly because they’re more a conversation piece than anything interesting or fun to have. With a good one, you can take it out for handling, maybe even walk around in public with it, but that’s all they do.

[I’m not expecting more from an axolotl, mind you, but it’ll be a photo subject and educational and study specimen, and I’m still a little on the fence about that, too.]

Others are very ‘outgoing,’ though.

unknown variety of hognose snake, Mid Atlantic Reptile Expo
I never found out the variety of hognose snake that this is, but it’s likely a captive-bred color morph, since that’s exceedingly common in the trade, and countless examples of such (mostly ball pythons) were in evidence. Despite the menacing appearance and the sharp nose, this one was super calm and curious, related by the vendor as being their most mellow specimen – since this was the same vendor as the false water cobra, that’s decent praise. As you can tell from the hand in the background, this is a much smaller specimen than the cobra.

And there were some other species.

unknown variety of scorpions fluorescing under ultraviolet light, Mid Atlantic Reptile Expo
Scorpions – to the best of my knowledge, all species – fluoresce under ultraviolet light, a trait I’ve been wanting to capture in images for years now; this doesn’t count, since they’re captive. We do have one or two species to be found a state or two further south from here, but my explorations have yet to unearth one. I don’t know the species and they appear on several different continents, but these look like the large desert scorpions of the southwest US. Curiously, those large, black specimens have a relatively weak venom, about like a beesting, while some tiny little, semi-translucent species found in some countries of the middle east can inflict a near-fatal sting.

unidentified lizard species, Mid Atlantic Reptile Expo
I didn’t note all of the species there, forgetting to snap the identifiers on some of the terrariums, so I don’t know what this is. I also had to do color-corrections for the wildly mixed lighting of the convention hall and individual heat lamps and so on – this should be reasonably accurate, at least much better than the original.

unidentified chameleon species hanging inverted from its terrarium lid, Mid Atlantic Reptile Expo
Same with this chameleon species – it’s confusing until you locate its eye. I could be talked into getting a chameleon, I’m sure – they’re just too bizarre, and generally pretty inquisitive while moving like they’re made of balky robotics.

handful of juvenile red iguanas Iguana iguana clustered together under heatlamp, Mid Atlantic Reptile Expo
These were listed as red iguanas, but on looking them up, they appear to be the same species as green iguanas (Iguana iguana,) so I’m guessing they’re a captive-bred color morph. If so, they’ll likely get a hell of a lot bigger than this. Iguanas do tend to be gregarious among their own species and will often pile together in nice heat sources.

juvenile Nile monitor Varanus niloticus in profile, Mid Atlantic Reptile Expo
This was listed as a Nile monitor (Varanus niloticus,) and if so, it’ll get a lot bigger than this too, even bigger than the iguanas – perhaps over two meters in length. I didn’t ask about this, however, and not only is the average smaller (yet still over a meter,) it’s possible that they grow only to fit both their feeding habits and available enclosure. Still, not a species for a 20-gallon terrarium, even if they do have nice markings.

Now, all of that was part one, because part two began on the same day after arriving back home. I was in the bathroom off of Walkabout Studios when I heard a rustling right outside the window. All of the photos from here on were taken with the smutphone – I know, I know, but I had to. You’ll understand why in a moment.

red-bellied water snake Nerodia erythrogaster exploring just outside bathroom window
Walkabout Studios is a basement office, and half below grade, so the window is right at ground level, and this rustling was right alongside my ear as I sat there. As soon as I was able, I scooted outside to confront my subject here, who was trapped in the corner against the retaining wall and made repeated attempts to escape through the glass into the bathroom. I managed to get a good hold of it without getting bitten, and thus do a nice photo session, albeit one-handed.

large red-bellied water snake Nerodia erythrogaster held in author's hand and extending up arm
This is a red-bellied water snake (Nerodia erythrogaster,) and final vindication of my efforts, though this was obtained by accident. You see, we are now in what I consider to be a prime location for water snakes, including cottonmouths, and I’ve been keeping a careful eye out for them, making several minor expeditions around the pond at night to try and locate them; it’s been frustrating that I hadn’t yet seen one, save for a tiny specimen a couple of weeks back. This one, a different but related species, is the largest example of red-bellied that I’ve seen, and the first I’ve handled – also possibly the largest water snake of any species that I’ve handled. That I found it a decent distance from the water while I wasn’t looking is somewhat ironic, but there you go.

red-bellied water snake Nerodia erythrogaster in author's hand attempting to bite the phone
I’m familiar with the northern and banded water snakes and know they’ll bite at the slightest provocation, but wasn’t sure if this extended to the red-bellied or not; the circumstances of its capture prevented it from making any attempt, since it ducked its head under a coil of its body just as I was making the grab, and so it never had a clear shot. Here, as the smutphone loomed close for the portrait, it demonstrated that it was indeed prepared to savage me – it’s being held with adequate firmness but not tightly, and this was a momentary strike (while unable to lunge) that coincided with my snapping the pic. I was also smeared with feces, a common defensive trait of snakes.

head-on shot of red-bellied water snake Nerodia erythrogaster in author's hand
There’s another defensive trait visible here that I don’t (yet) have a comparison image to show distinctly, but water snakes (among others) will extend their upper jaws wider when threatened, flattening out their heads to appear broader – you can see how the cheekbones are much wider than the eyes. When relaxed, the head will appear much narrower than this. Whether this is to mimic a venomous pit viper, like both the cottonmouth and copperhead, or simply to appear larger, I can’t say. But at least the smutphone produced decent sharpness, unlike the next photo.

head-on shot of red-bellied water snake Nerodia erythrogaster in author's hand with tongue extended
Timing smutphone pics is a lot harder than with a real camera, but a real camera is a lot harder to juggle with one hand full of defensive snake. I’m pleased that I did manage to capture the tongue extended (the snake calming down just a tad,) but naturally the phone’s focus wandered at that moment, because what the hell else was there to focus on?

After this session, I released the snake back were I’d captured it, where it sat and watched me warily for several moments, unconvinced that I wasn’t done fooling around. But it rounded out the day nicely, so I was pleased. And unscathed (well, except for the feces) – can’t argue with that.

So, didja?

Did I observe World Migratory Bird Day, you’re asking? Did I even complete the goal I set out for myself in an earlier post? Well, yes, though I actually had two, and one remains only half-completed.

First off, two days before the holiday, I was surprised to suddenly see a female wood duck shoot into the nest box without warning, revealing that it was currently in use, and so one of the goals was to confirm this with photos or video. And while I was staking that out, sitting in the yard some thirty meters off with the long lens trained on the nest box, I completed the other goal.

confirmed Mississippi kite Ictinia mississippiensis flying overhead
While obtaining nothing dramatic or even fartistic, I snagged enough images of the frequent visitor to confirm that it is indeed a Mississippi kite (Ictinia mississippiensis,) which aren’t typically found here, though we’re not far outside their plotted range.

confirmed Mississippi kite Ictinia mississippiensis flying overhead
That’s enough color detail to nail the ID down, and I’m pleased that it chose to wheel directly overhead while I was sitting out there (and that I glanced up at the right time to spot it.) These pics were taken straight up while I should have been watching the wood duck nest box, but this was a goal and I needed to fulfill it. While I have no idea how many there are, or if there’s a nest, et cetera, I see one overhead frequently enough that I’m sure it’s staying in the immediate area. I’ll keep you posted with any better pics.

As for the other goal? We’ll let the video cover that bit.

And a few photos done outside of the video clips.

suspected juvenile American robin Turdus migratorius just chilling in the yard
Like I said in the voiceover, I believe this is simply a juvenile American robin (Turdus migratorius) out of the nest less than two days, still expecting to be fed, though I never saw any sign of parents – and may not have, if they were trying to get junior here to feed on its own. While I had initially suspected this guy was suffering from Avian Influenza, it matches no symptoms and has more of a juvenile appearance. Am I seeing the barest hint of remaining baby down around the neck, in that video? You decide.

soaking wet red-shouldered hawk Buteo lineatus perched atop light pole during long downpour
While the winter was full of sightings of a pair of red-shouldered hawks (Buteo lineatus,) by early spring these had largely stopped, and the nest went unfinished, but we were hearing their calls down near The Bayou and so believe they’d simply constructed a new nest down there. Abruptly, however, one has made some recent appearances in the yard, and we believe it’s trying to snag one of the wood ducks that come up for feeding a few times a day – I saw some actions that almost confirmed this. Let me tell you, The Girlfriend is definitely conflicted about this. She was following the hawks’ appearances almost as closely as I was, and was delighted to see them building a nest right in the backyard, but then they disappeared and we started following the wood ducks. I’m sure she favors the ducks now, and while she recognizes that this is simply the balance of nature and how the duck population is managed, she’s not going to be happy to find that the hawk has snagged a meal or two. And by the way, this pic is from the same day in the video where it simply poured all day long.

prothonotary warbler Protonotaria citrea peering from nest in tree cleft
A better look at the prothonotary warbler (Protonotaria citrea) as it peers from the nest. I believe both the male and the female were visiting the nest, but the male was at least nearby and making a fair amount of noise, which is what drew my attention in the first place as I was out scouting for beavers. My position to achieve this shot was slightly precarious, a little too close to the stream edge, and I was having flashbacks of last year’s World Migratory Bird Day – this is certainly as good as I’m going to see the nest, but perhaps I can stake it out and see the young fledging out.

And finally,

juvenile summer tanager Piranga rubra showing color changes between immature and adult
While I was watching the wood duck nest box, and getting the video of both the red-shouldered hawk and the American robin, and getting the confirmation pics of the Mississippi kite, this one landed high in the tree nearby, and so I once again detached the camera and long lens from the tripod to aim towards a new subject. Video was out of the question because of the high angle needed and my inability to adjust the tripod like that without spooking the bird, which was quite close. This is a summer tanager (Piranga rubra,) showing the mixed colors that occur as a juvenile molts into adult plumage, and while I would have liked to have had a little better light on the bird, at least the plumage and background colors work well together.

Meanwhile, I never did capture the wood duck entering the nest box, and after a couple of long stakeouts with no activity whatsoever, I’m suspecting that at some point when I wasn’t watching, the young had hatched out and they all bailed the nest, which apparently occurs very soon after hatching; unlike other birds, the mother does not feed the young with regurgitated food, and instead they’re out foraging from the start. So I’m now watching for both signs of her return or evidence that she’s leading a brood around someplace. As always, you’ll see updates right here as I get them.

Numbers game

Several days back, The Girlfriend found a potted blue lobelia for me, which I’ve been intending to get for a while, because they’re blue, and I mean, seriously blue – more blue than any flower I’ve seen, more blue than almost any thing I’ve seen. Note that this is not the US native great blue lobelia, or blue cardinal flower, but an African import, Lobelia erinus, of the Campanulaceae Family instead. And one day in passing, I decided to do a couple of frames of it to record that color. But even in the LCD as it did that 2-second preview, I could see things were off. This is what the camera produced:

blue lobelia Lobelia erinus rendered far too purple in-camera
That’s… not at all a color match, or even close. The flower is by no means purple, it is as pure blue as one could reasonably expect or define. I had to do a bit of tweaking to get the image close to what the flower actually looks like to our eyes (or at least to mine):

blue lobelia Lobelia erinus image edited to reflect true colors more accurately
Note that this wasn’t a simple color-tweak, or adjustment to saturation in individual channels (like desaturating the Magenta, which I thought should have worked and instead made virtually no difference.) I had to not only desaturate Magenta almost entirely, I had to adjust the Hue of the Blue channel by no small margin to get it to look this way – thankfully, this had little effect on the rest of the image and thus looks pretty damn close to natural.

But this got me curious as to why this occurred, to such a large degree, and naturally how much this was affecting other images. My initial thoughts were that the sensor had a little too much sensitivity to the violet and ultra-violet, the latter being invisible to us, and this is what was captured in the image; I already know that CMOS sensors can reach a decent distance into the invisible-to-us infra-red. But no – they capture virtually no UV, and the answer instead appears to be complicated and a curious aspect of physics and CMOS sensors.

First bit: broken down into a spectrum, the sun emits less blue than green or red, though of course this is a spectrum and doesn’t bear these nice distinctions of “blue,” “green,” or, “red” that we want to apply to it. Nonetheless, both digital sensors and our eyes break down light into three primary colors in this way (no, yellow isn’t included – that’s a pigment-based thing from mixing paints and dyes.) Other colors fill the gaps and might be considered combinations of these three to varying degrees, but again, spectrum; it’s our eyes and digital sensors that count them as combinations.

Second bit: CMOS sensors, used in most commercial digital cameras, count photons in each of these three primary colors. But the shorter wavelength of blue means that blue has more energy per photon. To use a brief analogy, it hits fewer times yet harder. But CMOS sensors are only counting the hits, and so, blue isn’t getting considered evenly.

Then there’s part three: The way CMOS sensors are made, blue has a tendency to scatter a little before reaching the sensor itself, so it gets reduced even more. Chances are, the software that interpolates the sensor output makes some adjustments for this, but if it isn’t captured/measured by the sensor in the first place, the software boost won’t have much effect.

So, just now, I decided to go into the individual color channels and see how they looked – they are below in order of Red, Green, and Blue:

unaltered image of blue lobelia Lobelia erinus separated into primary RGB channels
As one would expect, Blue is very bright in the flowers themselves, which is as it should be. But the flowers also have a distinctive presence in Green and especially Red, which isn’t, or at least, not to my expectations. I’ve broken down images of red flowers into separate channels and Red is of course bright, while Green and Blue drop almost to black in the channel rendition – like, below.

image of hibiscus blossom with separated RGB channels
[Note, too, that the Blue channel is often the blotchiest and least detailed within most images when broken down in this way, probably due to that photon count vs. energy bias.]

Now, is there a way to fix this? No – not without a new sensor/camera that is probably very expensive, and quite frankly, the impact is trivial; this is the first circumstances where it became really noticeable, though since I shoot nearly all the time in Daylight White Balance, I tend to tweak images that need it anyway. It’s easy to get bogged down in pursuit of some definition of “accurate,” but ultimately pointless; between the shortcomings of dynamic range in both sensors and monitors, and the subjectivity of individual perception (is the blue I see the same as the blue you see?), there’s no way to define “accurate” reasonably anyway. In the situations that call for it, I’ll fix it in post.

Tiny badass

Or at least, badass-looking, anyway. The specimen you’re about to see is only about 20mm in leg spread – not especially large as far as spiders go, and it only appears this impressive because we’re going in so close. This was found within my outside trash basket, which I have because the resin 3D printer produces some heavy fumes, as does the stuff used to clean it all up, and so I have a basket outside to discard this stuff into. The spider, however, probably only wandered in there by accident and couldn’t scale the smooth plastic sides. I vaguely recognized it but couldn’t quite place the Family, and needed some detail photos anyway.

male Atlantic purseweb spider Sphodros atlanticus slightly overexposed
I was still zeroing in on the flash exposure so this one is a little over-exposed, but that’s okay since it shows more detail from the pure black spider – I really should have set up a white box instead, but it was running late on a busy day. This is an Atlantic purseweb spider (Sphodros atlanticus,) and BugGuide.net provides very little information about the Family overall, much less the species – the identification was only pinned down through careful comparison of the images, after finding the general place to look through an Ecosia search. Other sources gave the habits and method of hunting, which is basically a small tube of silk against tree trunks that likes a lot like a small branch, and so I went out looking for just that, so far finding nothing.

But the real trait that attracts attention are those chelicerae.

frontal view of male Atlantic purseweb spider Sphodros atlanticus showing pedipalps and chelicerae
Those are the appendages in front of the spider that house the fangs, in this particular case taking up better than a quarter of the total body length; the eyes are on top of that knob on the cephalothorax, here appearing practically in the middle of the body, while those two big blobs in front, almost like buttocks, are the chelicerae. Alongside those, down low and looking like forelegs, are the pedipalps (only one seen clearly here, the ‘leg’ not tipped in rust color,) and the club-ends of these peg this as a male. Which is what anyone is most likely to find wandering about anyway, because the females stay almost entirely within their web lairs and the males go out trying to locate them.

But we need to see those chelicerae better (yes, we do.)

male Atlantic purseweb spider Sphodros atlanticus in defensive pose clearly showing chelicerae and fangs
The movement traits and especially the defensive posture when provoked (by poking gently towards the cephalothorax with a small probe) put me in mind of a trapdoor spider, though this was much smaller than that one. The reddish-brown fangs are clearly in evidence, ready to deal with hooligans, but also notable are the serrated ‘teeth’ beneath, able to grip prey quite handily it would seem. Again, we’re looking with high magnification – those fangs are 2mm in length at best, but that’s still pretty large for any spider, much less one this size. I never try to provoke actual bites at any time – I’ll let Schmidt do that – and I have no idea how toxic their venom is, but since it isn’t listed as distinctive in any source I’ve found so far, I’m guessing it isn’t as bad as this image would seem to imply.

Once I had the name ‘purseweb spider’ in hand, it brought to mind some shots that I’d gotten many moons ago, and I went looking for a comparison. Sure enough, I’d likely gotten the Family (Atypidae) at least before, as newborns just outside the nursery:

brood nest of newborn likely purseweb spiders, Family Atypidae
I got this shot just a little over ten years ago, while scouting out a new location for photos and not in possession of the macro flash, so these are by natural morning light under the forest canopy, and of course the spiderlings here are very small. But those huge chelicerae are plainly evident here, and more so as we crop in tighter.

crop of previous frame of newborn likely purseweb spiders Family Atypidae
Also noticeable are the long forked spinnerets at the hind end, which the adult has too, I just didn’t get a frame that showed them as well – I was concentrating on the chelicerae, if you haven’t fathomed that by now. But yeah, they are definitely funky and recognizable spiders, though next time, I’ll use a white box for the photos.

Two little unknowns

Or at least, they were for a short while.

Back when the internet was out, I found two new subjects for photos and posts – except, i didn’t recognize either of them, and couldn’t post anyway. Now, it’s true that I have the Audubon Guides to both birds and reptiles & amphibians, but I’ve found them to be so inadequate that I haven’t used either in years, mostly from the lack of illustrations; both classes of animal often have numerous color variations, and Audubon has a wicked tendency to have one color photograph of any species. So I didn’t even bother trying, and simply waited until I had access again to online guides.

Okay, this one wasn’t completely unknown, and I’ve actually photographed it before, but merely once, and thus just one color variation; this is an eastern narrow-mouthed toad (Gastrophryne carolinensis,) chilling cooperatively in my studio setting. Actually, not all that cooperatively, because the moment I set it down into the nice natural-looking leaf litter, it disappeared beneath and had to be fished out. Multiple times.

I made it a point to do several perspectives and get all of the details that I could, just in case it was something new to me, plus the fact that I intended to release it before I had access to identifying guides, so I didn’t want to miss any crucial details. This is the species whose call sounds a lot like a goat, and with all of the frog and toad calls we’ve heard since moving here, this one has been conspicuously absent, but if memory serves, they start calling later in the spring or early summer anyway.

Too many amphibian species have identifying markings on either the belly or especially the underside of the legs, so I made sure to get this. Amphibians really don’t like being upside down, and it was a struggle to hold it in an adequate position without either injuring it or obscuring what I was after, but I snagged a decent frame without mishap. And it escaped across my desk only once.

A scale shot of course – this is typical size for the species. By the way, I’ve seen the common name as both, ‘eastern narrow-mouthed toad,’ and, ‘eastern narrowmouth toad,’ so use what you like – I personally use, ‘Guido.’

And now the other.

red-bellied snake Storeria occipitomaculata in studio setting
Another studio shot, this specimen was quite small but active, and it was a struggle to keep it within the shallow pan I was using for convincing ‘ground.’ This is a red-bellied snake (Storeria occipitomaculata,) also ‘redbelly snake,’ so again, whatever you like – it’s ‘Portnoy’ for our purposes here. The namesake (theirs, not mine) isn’t visible unless you pick it up, or it leaps at you from a low-hanging tree, which actually never ever happens, plus you’d only give a shit if you were extremely ophidiophobic, because it’s a tiny snake.

Actually, I find the back markings pretty cool too, and that rusty head, but of course the belly gets the attention. This one seemed vaguely familiar to me, but only through indistinct memories of photos, because I’m pretty sure I’ve never found one before, despite the fact that they supposedly can be found all through North Carolina.

They have a nice little ‘collar,’ and it bears a faint resemblance to the markings of the brown snake, which is a related species. They also have a curious habit that I realized, once I had access to a guide but not the snake anymore, that I did just barely capture in the next two frames.

When agitated and trying to appear threatening, this species can spread its upper jaw a little wider, giving it pronounced ‘lips’ and making the head broader, which I thought I was seeing but had never witnessed before, though many snake species do some variation; cobras, as everyone knows, can flare the skin behind the head and down the neck, while hognose snakes can flatten their entire forebody, and even watersnakes can spread their heads wider, as you’ll see in an upcoming post.

I can’t recall if this bluffing extended so far as to strike at me anytime I was handling it, but seriously, have at it, little dude – you’d be lucky to get a decent purchase on even my little finger. Their diet is mostly slugs, and this helps explain why I found it under the lid of the compost bin which we’d left setting on the ground, and to where I returned it.

Nine more pics out of the backlog, but still catching up.

They do own the property, after all

Carolina anole Anolis carolinensis clinging to post lamp
While trying to catch up with the backlog, naturally enough I went out yesterday and added quite a few photos to the queue, under a couple of different topics – one step forward, two back and all that. This post may help alleviate it a bit though, because it had more photos (and some brief video) dedicated to it than any other topic until yesterday, and so we return to the Carolina anoles (Anolis carolinensis,) since they actually own the property and are simply allowing us to live here, as long as we pay the mortgage and taxes and so on.

The lamp post out front (which has just been replaced, an act that may well get us evicted) has been a huge favorite of the species, almost as popular as the south side of the screened porch; once the temperatures topped 10°c and the sun was out, so were they, but a distinct addition occurred about a month ago.

That’s an anole on the post, presently brown though that can change in mere seconds, with a female American five-lined skink (Plestiodon fasciatus) on the bricks at the base; the two species inhabit the same regions but have slightly different habits, the skinks being more terrestrial and only occasionally climbing, while the anoles spend little time on the ground itself. There’s a fair amount of crossover, but overall, you’re far more likely to see them like this: the anole vertical, the skink horizontal. Notice that there are a couple of green patches on the anole’s body, evidence only of something blocking the direct sunlight from the skin moments before, failing to trigger the biological system that causes the skin to turn into a more heat-absorbing brown. The skinks, however, only change color with maturity, though it’s different colors for the males and females.

Now we start to see the difference:

Notice how, only a minute later, one of the green patches has changed over to brown with the exposure to direct sunlight, though the other is lagging behind a little. It had changed soon afterward, though.

Now we have confirmed that the anole is male, since he is displaying his dewlap, that big pink thing under his chin. This serves two purposes: as a territorial display and as a mating display. While the skink is right there (and female,) it is unlikely that this display, whichever it is, is intended for the skink. They’re already too close together for it to be likely territorial, plus they’ve been this close for some time without it, and the anole isn’t going to try and seduce a skink. What I’m guessing, though I didn’t directly witness it, is that there was a female anole someplace nearby, since the post environs has numerous places where the anoles can be sitting without easily being observed.

We can see the subtle variation in the different displays in a couple of clips:

One thing not mentioned in there is that during contentious territorial disputes, actual fights between males, they display brighter colors and very distinct dark patches on the cheeks, like that seen here.

The skink made several appearances, but was always quite shy and would disappear at most close approaches, so it took me a little while to get a more direct portrait of her.

She’s a hefty specimen, big enough that I almost suspected she was a broad-headed skink instead, but I think we’re outside of their range here. The males will have more reddish heads, while the juveniles will generally sport higher contrast in their markings and an electric blue tail. Also, skinks are shiny and quite reflective, while anoles are not in the slightest. Since these photos, I’ve only gotten occasional glimpses of this one individual, yet a few others can be found around the property from time to time – just, not one-tenth as frequently as the anoles.

The anoles are also fond of sleeping in odd perches well above ground, at least when it’s warm enough, and this is enthusiastically evident when I venture out on the other side of the main pond, bordering The Bayou. Here, by the light of the headlamp, I can often see three or four from one spot.

I’m always impressed by their ability to sleep confidently while clinging vertically, and this one is as vertical as it appears. I’m guessing that either they have a mechanism, like bird feet, that can keep certain muscles tensed even while asleep, or that their negligible weight can hang easily from single toenails dug into the leaves or bark. I mean, look at this: the toes aren’t even wrapped around anything. And no, it has nothing to do with moisture, because unlike the tree frogs, anoles are perfectly dry and in fact take cover at the first hint of rain, or even when I play the misting bottle over them, regardless of how hot and dry it’s been.

I kind of liked the perspective of this one:

Can’t tell what the front feet are doing, but the backs hardly seem to be doing anything, so I doubt they’re supporting any weight. No matter what they’re perched on or what the conditions of the day were, anoles always seem to go as pale green as possible at night, though whether this serves a distinct purpose or is simply their ‘base’ relaxed coloration, I can’t say. I do know that they often collect dew overnight in the right conditions, presumably drinking it come morning, so perhaps this assists that somehow.

And then there’s this one:

The hind toes, at least, look like they might be hooked, but damn, I’d have a wicked headache in no time if I tried to sleep like that. When approaching with the headlamp, I will often see the anoles crack open their eyes, though honestly, I think it has more to do with how much noise I make than the light itself – I have plenty of pics where they never seem to notice the light, or even the bight bursts of the camera strobe.

This one noticed, but that was partially because I had to shift position for this perspective and couldn’t do so silently:

This one was comfortably horizontal, but on a plant that was surrounded by undergrowth and foliage, so not only was I unable to move quietly, I couldn’t even approach without something that I was trying to brush past disturbing the very plant that the anole was snoozing upon, causing it to sway slightly. Nonetheless, this was the extent of the reaction that I got from the anole, but we can perhaps credit the headlamp with that, since all they can likely see is the glare of the light and not me or the camera in any distinct manner. I waited patiently, and after less than a minute, the anole was dozing off again.

Now, if I touched one of them, they’d become much more alert and may scamper off, though whether they can actually see where they’re going at night is unknown to me; I can’t, at least without a light, so I can’t observe them to know how well they can. I’m inclined to say that their night vision is close to nonexistent, since plenty of tasty insects are active at night so it would be a prime feeding opportunity for them – provided the nights are warm enough, anyway, and that may only be a narrow range of time for them.

That’s a few pics down, and some of the older ones – we’re making progress, as long as I can maintain zero population growth for a little while at least. Plugging away…

With a bonus

While getting all of the photos for the latest Estate Find, a set of bonuses simply walked right in, literally. I was sitting on the steps down from the deck with the camera and long lens in hand, just snagging pics of opportunity of the dusky Canada geese, when I spotted activity from the edge of the pond.

I don’t have to tell you this is a wood duck (Aix sponsa,) do I? There’s a bold pair that’s semi-tolerant of our presence, provided that we’re up on the deck and not moving much or making noise, but there’s a distinct limit to this, and they’ve never ventured any farther than just inside the pond edge, nor have they even approached if we’ve been down off the deck in the yard – that’s always enough to send them to the back of the pond, if not flying off down to The Bayou. But here they came, and I kept the camera raised to my eye with the barest of movement and simply fired off frames.

Now, the dusky geese with their geeseling were half the distance to us and foraging unconcernedly, and we thought that perhaps the wood ducks were curious about the young-uns. Whatever – I was watching in fascination.

I call this one, “Estate Gothic” – it will be a print soon. Look at the duckweed still on their breasts.

The idea that they were curious about the geeseling seemed to be disproved when they went past where the geese were, closer still to me on the steps, happily snagging the corn that is usually present (because we’re conscientious/obsessive about keeping everyone fed.)

mae and female wood duck Aix sponsa finally realizing they were getting close to photographer
At this point, I believe the male finally realized that they were drawing close to a human, or that that big lump on the steps was alive; they were now about eight meters or less off, and this is only slightly cropped from full-frame – she’s laying down. I’m honestly not sure what was going through their heads, because they’ve demonstrated how sharp-eyed and sharp-eared they are, and their awareness of how the landscape has changed (for instance, by the presence of people, no matter how still we are.) Did they honestly remain unaware of my presence, or did they get lulled into a sense of security by the geese (which has never been the case before – wood ducks make their own decisions.) Or were they just pushing their tolerance of us because we’ve not only been putting the food down, we’ve been otherwise unassuming and certainly non-threatening? I have to note that the wood ducks rarely even see us throwing the corn out because they typically fly off before they could witness it – these are the only pair that I feel comfortable saying have actually seen it, and even then the motions were usually enough to send them off.

male wood duck Aix sponsa now quite alert to the presence of a human
Here, the male is now clearly aware and not comfortable with it, talking quietly to the female in their peeping, wheezy tones; only a few moments after this, they took flight back down to The Bayou. Still, this was encouraging that perhaps this pair will become tolerant enough that they’ll hang around in our presence – maybe not close approaches, but at least not fleeing for safety. And this is by far the closest that I’ve been in daylight when they could see me clearly – I’ve gotten closer at night when they were blinded by the headlamp and so unsure just were I was, we can’t really count that.
