Local news and weather

About a week ago, we were still struggling with a faint drought, having had no rain in roughly two weeks while temperatures were peaking in the 30s, and the rain barrels were rapidly emptying as we kept the various plants watered. That evening I took the misting sprayer and went around to the likeliest plants to give them a thorough misting, knowing the mantids, at least, would be pleased with it. I saw a couple, but they’re still small enough that a heavy rain is a hazard to them, and they jumped out of direct contact; I knew they’d still slurp the moisture from safe locations, so I considered it more beneficial than mean. One in particular though, out on the lizard’s tail plants (Saururus cernuus) in the backyard pond, was quite appreciative and stood bravely in the mist as it wafted down, but a little less brave as I leaned in close with the macro rig. It took a few attempts before I could get a straight-on portrait.

But after the first few tries, and as I started to ignore the mantis in favor of anything else on the same plants, the mantis became bolder and started showing off its agility.

This one appears to have taken up residency on the plant, happy with its own moat I guess, and is growing noticeably larger so it appears to be finding enough food too. With the lizard’s tail flowers just coming into bloom (everything is running late this year,) I’m not surprised.

Around the house at the front garden, a bit of movement after misting attracted my eye, and I’m not sure if this guy purposefully came out of hiding to bask in the falling moisture or not.

Most times, when I’ve seen the treefrogs while I’m misting, they seem to either just hunker down when it passes over them, or actively jump away, not frantically, but not seeming to relish the direct contact. What little movement I saw from this green treefrog (Hyla cinerea) however, seemed to be in effort of getting out in the open. It was quite small, larger than my thumbnail but smaller than the top joint of my thumb, and a little reluctant to pose, but you know how expert I am at convincing species to be pretty.

I didn’t see it again, which isn’t too surprising – some of the nights have gotten cold, and treefrogs can easily decide to switch their hunting spots, but just today as the downpours rolled in (finally,) I found it again in the same area, less than a meter from the last sighting, and again, appearing to delight in the water.

That one big water drop on the day lily leaf gives an impression of scale, at least, and about the only one I’m going to manage, because the frog’s still a bit spooky, which is fine; they should remain aware of dangers. I could take to wearing a ‘friend of treefrogs’ badge I suppose, but you know how often those are counterfeited by confidence hustlers; nobody trusts them anymore.

Profiles of Nature 22

head-on yellow-bellied slider Trachemys scripta scripta Ermintrude
This week we meet Ermintrude, who specializes in playing unsettling parts because, man, even those nostrils stare into your soul. Ermintrude didn’t actually ‘get a start,’ as such – she simply walked (slowly) onto a set and said, “Put me on the payroll,” and they did, afraid of what might happen if they didn’t. She’s actually a very nice person, but no one ever sticks around to find out; she was scheduled to be the second Profile of Nature, only it took us this long to finish interviewing her. And we’re still worried about how she might take this. Ermintrude was named after a great aunt – not her own, just one her parents had heard of, though they actually got the named mixed up with that lady that didn’t like oatmeal. She (Ermintrude, we mean,) (the present one, we mean,) is very active politically, running (slowly) for office at least three times a day and exercising her prerogative on a regular schedule; she insists she’s quite fit, but you know it’s hard to tell with turtles. She enjoys listening to Warren Zevon, which we consider physically impossible, so we’re guessing she’s trying to work some angle. She also owns property in seven states, or at least, she’s wee’d on it. Ermintrude’s favorite songbird is the one that goes, “zakka zakka phweet vornto vornto gobba snee wi shoy bay.”

Not to be a downer, but we haven’t even reached the halfway mark yet, so take a pill and come back next week!

Throw numbers in the air

Over at Universe Today there’s an article about rewriting Drake’s Equation, and after reading it some time earlier, it’s been stewing in my mind a little; potential posts about it have changed several times, and resulted in this one.

Long story short: an astronomer named Frank Drake wrote out a simple equation, back in the sixties, to examine the possibility of contacting alien life. This was right at the beginning of advanced radio astronomy, and it took place for a meeting that would give birth to SETI, the Search for Extra-Terrestrial Intelligence, a project that is still going on today. I’ve written about this equation several times in the past, largely regarding how little it tells us and the bare fact that it’s all speculative. Recently, another astronomer named John Gertz proposed several changes to the equation, based on information that we’ve gathered in the time since. Here’s what he produced:

The number of spots on the sky within our field of view
X
The fraction of stars with planets
X
The average number of bodies within each that could engender life
X
The fraction of those that actually do give birth to life
X
The fraction of systems with life that evolve technological intelligence
X
The fraction of technological life that is detectable by any means
X
The duration of detectability
=
The chances of contact.

It was gratifying to see several of the points that I’d written about in the past get covered, but that’s just ego talking. A few other points were covered too, but those weren’t included in Gertz’s rewrite of the equation. But what came to me as I hashed this out was that there are three classifications of the information.

The first three factors in the equation are cosmological, able to be determined at a distance and hewing within reasonable estimates based on our knowledge of physics – they’re the ones we have the most confident numbers of (and it’s not all that confident, despite the huge upsurge in exoplanet knowledge in the past two decades.)

But the third is also biological, as are the fourth and fifth; they rely on the likelihood of life developing, moreover to a certain level, and we know nothing at all about that except for the conditions that we know are hostile, and that’s assuming life forms very similar to our own. Within our knowledge of physics, it seems that a carbon-based life form is most likely by far, but how life developed even on our own planet is still up for grabs, to say nothing of how likely this is to occur again elsewhere. These numbers are little more than wild guesswork, because we have nothing to support them. It’s the reason why I’ve said that the Drake Equation wasn’t actually an equation, because there’s no way to support it and testing it would require numerous examples of just the kind of contact it’s being used to predict.

The sixth and seventh factors are sociological, depending on the life from the previous factors actually engaging in practices or developments that we’d be able to detect, and to say that we’re spectacularly out to sea on these is putting it mildly. Intelligence isn’t this discrete concept; it’s a gradient, a spectrum of mental activity, and no matter what level you pick, you can find that it’s not necessary for life to sustain, not guaranteed or even likely to increase as a species develops, and possibly not even a lasting benefit (given how rapidly we’re depleting our resources and how serious our weapons of ‘defense’ are – targeted solely at our own species as well. But then again, as others have said, maybe we’re not actually intelligent.)

And as I’ve asked before as well, what are the chances of an extra-terrestrial species finding it a good idea to even make themselves known, much less initiate contact? Their own environment is going to guide how they develop, so are they competitive, or protective, or even just incurious about other life? It almost stands to reason that any species initiating contact does not feel threatened by this, and what should we infer from that?

Then there’s the attenuation of signal aspect. With all star systems light-years distant from us as well as one another, the ability to even transmit a signal would require enormous energy, becoming weaker with distance, so the species would have to be okay with disposing of this energy in the slim chance of making beneficial contact.

And if/when they do, what are the chances that they (or we) could even comprehend anything more than bare proof that it’s not a naturally-occurring signal? By what means are either of us going to translate any message?

So personally, I’d add a couple of factors into this equation, down at the bottom:

X
The fraction of technological life that is motivated to make contact
X
The fraction of technological life that would generate a signal that could reach us
X
The fraction of those signals that we would recognize as such
X
The fraction of technological life that would not present an enormous hazard to contact

That last one kinda throws a wrench in things, because it’s another number that we not only can’t calculate in the slightest, it can only be determined by taking the risk in the first place. I’ve mentioned before that we’re a stupidly gambling species, accepting certain risks if the reward seems worth it, and all too often the reward is entirely subjective. When we’re talking about an advanced species – one more advanced than us, since we’re considering it capable of something that we aren’t, yet – the risk of contacting something that could eradicate us is unknown in quantity, but undoubtedly present. For… what reason, really? Our curiosity? The chance that we might get some beneficial knowledge from them? The rather base instinct of being social? Yes, the idea of hostile aliens has been a science fiction trope for decades now – which doesn’t make it untrue in the slightest; some clichés are entirely accurate. Passively listening for signals likely entails little risk, but then, what do we do when we receive one? How low is the likelihood of any extra-terrestrial civilization openly transmitting useful information? Assuming for the sake of argument that we actually figure out how to translate such signals, how do we then figure out what the risks are? Are we going to psychoanalyze another species, much less based on their selected (and likely simple) transmissions? How trustworthy could we possibly consider this?

It’s funny; the more I think about the subject, the more I’m convinced that wild imagination and wishful thinking are playing more of a part than rational consideration. Receiving a definitive signal could be exciting and fascinating, but what happens after demands some careful thought.

But then, ‘snot art

sunset over sound with gazebo and kayakers
Yeah, another from this vantage, but hey – we had the view right out the back decks, so we used it, okay? What would you do; go down among the trees where you couldn’t see squat? Gimme a break…

We didn’t know the kayakers, either – they were from one of the neighboring houses on the sound, the dock with the green heron altercation. But I did wait until they were in the best position, composition-wise, and fired off several frames, getting this one with both oars raised (which would have been almost impossible to time, given the different cadences on their strokes.) There’s also a boat going by towards the back, in the main channel, but that’s almost invisible and doesn’t add much to the scene regardless, too close to the horizon band of blackness.

By the way, I actually had the quadcopter out there, a little lightweight jobby that A) didn’t have the best camera available and B) wasn’t strong enough to fight even the lighter breezes present most times out, really, anywhere in the vicinity. I made a couple of attempts to do a sweeping circle view of the sound, condo, and environs, but watched it driven helplessly off to the southwest, unable to make headway against the shore winds, until I grounded it before it passed out of range or over the water. Not sure if I’ll ever invest in a serious one or not.

I’ll take this opportunity to mention that Saturday, June 5th, is National Trails Day (for realsies,) so you can plan accordingly and thank me later on – cash is always good. It’s the day when we at the very least take advantage of the nature trails in our area, but also help maintain them and perhaps even help create new ones – responsibly, of course. Take only photos, leave only footprints; pack it in, pack it out; get bitten by a venomous snake, make sure you run around blindly until you stumble off a cliff and shatter your smutphone. I’m not sure who created that last one, actually. The weather around here is not looking promising, but we’ll see what happens – there are a few places that I should check out, though I should never need the impetus of a holiday.

I’ll also use this space to mention that this is the 130th post for 2021 – not a specific milestone, but a comparison. Last year I set a personal record of 233 posts for the year, the highest in the history of the blog, and this year, I’m well past the halfway mark and it’s not even June yet. Last year was also a record for photos uploaded, and at 392 so far this year, I’m well past where I was last year at this time (355,) but I’m gonna have to work hard to beat the gout of photos that went up in October (192.) We’ll see what happens. But I could have separated all of these out into their own posts, and didn’t, so I’m not being too manipulative, at least…

May be not

Since today is May but tomorrow is not, that can only mean one thing: it’s time for the end of the month abstract! Did you have your alarm set to get up early just to see this? I bet you did…

Of course it would have to be from the beach trip, and in fact, we have two, just to let you decide which one you’re least indifferent about.

Stunning composition, textures, poignancy, atmosphere… what more could you ask for?

You didn’t get any of it, but keep asking. It might help someday.

Meanwhile, birds

As I’ve been whittling away at the trip photos and video, I’ve still been out getting current photos – I’ve just been setting most of them aside. So we’ll play catch-up a little here, concentrating on the avians this time around.

On the same day that I snagged the angry bird, I got a couple of others in the immediate vicinity, which means at the neighborhood pond. I would have missed this one entirely if it hadn’t attracted my attention.

great blue heron Ardea herodias in dead tree
This great blue heron (Ardea herodias) was hidden from view until I was almost directly underneath, not to mention that I was watching the pond edges for the green herons and snakes, but I was forced to look up by some soft grunts, which I can only assume were purposeful, though whether this was a half-hearted warning to me or simply commentary on my bald spot, I cannot say. Regardless, the heron stayed put as I passed underneath, which was almost startling given how spooky the herons have been over there for the past year or so, and descended down to the water’s edge to fish once I had gotten a safe distance away.

But we need a detail inset of another frame.

great blue heron Ardea herodias in closeup with twigs in the way
It’s a shame about the twigs, but this was one of the few gaps in the trees that allowed an unobstructed view, and I could at least dodge a little to get the eye clear. We’re talking somewhere around 10-12 meters distant, so, not far at all.

I mentioned the angry bird in there, so here’s a photo from a slightly different angle, before I managed to get head-on, just to illustrate – the heron really was crouched with neck fully tucked, relying on being motionless to avoid my attention. Ha! Like that ever works!

crouching green heron Butorides virescens
[Actually, it may work an awful lot, and I’m just incapable of telling you how often.] Not the sharpest pic, but of course, once I saw the other, that had to be the one used (I’m gonna force you to click on that link if you haven’t already.) This heron was not quite directly underneath the great blue, being on the opposite side of a narrow channel, but they were within easy sight of one another, and I have their photos intermixed in the folders because I was switching back and forth between the two subjects.

A little further on, I glanced into a bluebird box affixed to a tree and thought I saw a shape in the shadows, so I fired off a couple of frames. This one’s enhanced slightly.

eastern bluebird Sialia sialis, possibly juvenile, peering from nest box
I’ve already seen the parents feeding young in this box, so either it’s one of the juveniles peeking out (because the parents only stay in the box after hatching to keep the young warm, which wasn’t necessary this hot day,) or they’ve already moved out and a second brood has been laid therein by another couple. I admit to not inquiring – it always seems nosy.

We’re going roughly in chronological order here, so now we jump many kilometers away. Crossing a branch of Jordan Lake a few weeks ago, I looked over to the side and saw what I took to be (judging from the size) an eagle’s nest, and could have sworn I saw a white head peeking out. Several days later, Buggato and I made the trip down there to get a better look than driving past in a car (I was not driving for that initial view.)

osprey Pandion Haliaetus sitting on nest
Morning was not the time to do this, since we were aiming too much into the sun and it washed out all of the color and contrast, but at least it was enough to see that it was an osprey (Pandion haliaetus) nest and not an eagle’s – though the osprey may have appropriated an abandoned eagle’s nest, because it seems kinda big for osprey, to me. Its behavior indicated that it was sitting on eggs, and so I vowed to return to keep an eye on things, even though, from this angle, there would be little to see until the young get to be decent-sized, but I might get lucky enough to see some fledging behavior.

It was just over a week before I returned, this time in the afternoon with The Girlfriend, so the light was better but, as yet, no sign of hatching.

osprey Pandion haliaetus standing on nest in better light
I’m not identifying this as a female, because the genders are identical and I’m not sure if the male takes turns warming the eggs; either way, this one spent a lot of time standing, fluffed out a bit, but it was a hot day so I imagine the eggs did not need constant body warmth. It’s also possible that the eggs had hatched, and Spouse 1 was waiting for Spouse 2 to arrive with more food. The region, a stump farm created by the flooding of the manmade lake, held more than one osprey nest and was overflown with other osprey, eagles (we spotted a distant juvenile,) herons, and crows, so it’s not unreasonable to expect a parent to remain in attendance for protection. Let’s have a closer look though.

osprey Pandion haliaetus on nest
We were a decent distance off, so no immediate threat at all, but we could still hear the osprey venting some faint cries. They do this often, especially on the nest, so it might also be a signal to the mate or warnings to any other birds in the vicinity – I can’t confirm or deny that they were about us, over on the bridge, but in this case the osprey sure looks like it’s eyeing us directly. We’ll see what develops with the young.

Okay, back to the neighborhood. A heron – whether it’s the same one or not I can’t say, because I’m not a spoiler – landed in some trees ahead and I slipped in for a couple of shots through the foliage, catching it panting in the heat before it flew off at my approach.

great blue heron Ardea herodias panting on hot day
I mentioned earlier that this year has shown us the coldest May that I’ve experienced since moving south, and then we went into sweltering temperatures – it was about 32°C that day. And now, as I type this, it’s dropped below 16°. Enough already. But we got our overdue rains at least, filling up the nearly-empty rain barrels, so that’s good.

A pair of green herons played chase over the pond, the same day as the heron shot above.

pair of green herons Butorides virescens almost mirror image
I just missed getting them mirroring one another, almost perfectly aligned; there’s no way you can anticipate or time this with them wheeling in circles, and I’m lucky to get the focus this good because none of the other frames came out worth a damn.

A day later, I did even more birds – lucky you. You may recognize these from Blurred Bird Day.

eatsern kingbird Tyrannus tyrannus posing haughtily
An eastern kingbird (Tyrannus tyrannus) provided a pose, I’m almost certain after it flew away from the nest. It’s possible this is intentional protective behavior, the contrasting coloration attracting attention as they fly away from the young, but remain close enough to keep an eye on things. Or maybe it saw the camera and is just vain.

You know, I’m glad my bird guide lists the various species under, for instance, ‘kingbird,’ and not, ‘eastern,’ because that would take forever to look up – ‘eastern’ appends a ridiculous number of species around here. The people involved in taxonomy need more creativity, and possibly a thesaurus.

Further on, a juvenile downy woodpecker (Dryobates pubescens) caught my eye.

juvenile downy woodpecker Dryobates pubescens catching the light
This one never made the faintest sound as it foraged, down low near the water’s edge which is far from typical, so I was lucky to see it moving when it was close. The lower light, however, did not play well with the hyperactivity of the woodpecker family, so it was a struggle to catch it while it paused long enough not to induce motion blur. It still had a little bit of a mangy, threadbare appearance, so I knew it wasn’t long out of the nest.

By the way, this is why bird guides can be slightly misleading; in the time since my copy of Sibley’s Guide was printed, the genus changed from Picoides to Dryobates. I have to double-check when doing these posts (though I don’t always do so.)

The Girlfriend had accompanied me on this outing, and we’d stopped to talk to a friend. While there, we heard the call of a pileated woodpecker (Dryocopus pileatus,) which our friend informed us was hanging around in the area. Shortly afterward, The Girlfriend spotted it poking animatedly down among the ground litter.

male pileated woodpecker Dryocopus pileatus foraging at ground level
Pileateds aren’t ground or leaf foragers, but you can see the fallen, rotting limb that it was working on. The view was terrible, the bird obscured until it raised its head, which it did for no more than .3 seconds at a time. I want to show you the full-frame, initial view.

full frame of male pileated woodpecker Dryocopus pileatus at ground level
Bearing in mind that this was 600mm, so without a long lens, mostly what was visible was the red head bobbing up occasionally.

I started working my way around carefully, being lucky enough to have a path strewn with wood chips running alongside the woodpecker, and a large tree that obscured his view of me until I drew close (this is definitely a male, from the amount of red feathers on the head – the female’s red feathers do not reach the beak.) Then I leaned out slowly and had a much better vantage, though the sound of the shutter made him aware that I was close.

under chin shot of male pileated woodpecker Dryocopus pileatus at ground level
He kept a wary eye on me but continued foraging, not too spooked as long as I didn’t move much. Pileateds are bigger woodpeckers, not quite as large as a crow, compared to the downy which is about the size of a bluebird.

profile of male pileated woodpecker Dryocopus pileatus at ground level
This is again full-frame, showing what kind of view I had – I was less than eight meters off. Note the leg sticking out there to the left; woodpeckers are tree-clingers, not ground perchers, plus they need the bracing of the tail to peck vigorously, so it’s an awkward position here. Now let’s go in for the detail.

closeup profile of male pileated woodpecker Dryocopus pileatus
I’m not knocking that at all, and editing this photo made me aware that pileateds have the reddest feathers that I’ve ever seen, far beyond cardinals, almost unreal – if I found a head feather in the woods, I might have been convinced that it was some dyed, decorative thing rather than their natural coloration. This will become a print someday.

That catches us up, at least for the birds. Some other subjects are coming later on.

Still at it

red sky before sunrise on North Topsail Beach, NC
It’s another attempt to get that elusive green flash on video, doing it at sunrise because sunset wouldn’t provide the view needed. The bad weather had cleared, but the temperature hadn’t risen yet, and it was far from comfortable on the beach; this just goes to show how dedicated and hardcore I am.

By the way, there’s a balance point when placing the tripod, because you want stable sand, which is generally the wet stuff near the point where the waves have come in, but you don’t want to be in the water at any point. Since it was nearing high tide, there also wasn’t a lot of beach to work with, and only a couple of meters away was the ‘cliff edge’ of the dune, the eroded high water mark in the sand not far from the steps down off of the primary dune; the moon was almost new, close to the sun, so their combined gravity was created the highest tides. It had an effect, as you’ll see.


Immediately after the video, I did just a handful of photos on the beach to take advantage of conditions.

debris linet at high tide with lots of shells and stones on the waterline
This is the debris that you heard in the video, directly underfoot and a bit hard on the soles. While I’m in water sandals all summer long, they’ll get completely filled with sand in the softer area between the primary dune and the wet sand near the waterline, so I generally take them off before hitting the beach and hang them from my belt with a carabiner, only re-donning them after hitting the courtesy footwash on the opposite side of the dune (which I also use on the tripod legs.)

I went a bit lower too.

very low angle on beach debris and foam against rising sun
Buggato would have been sorry to miss this, because I didn’t sprawl on the beach to get this frame, but simply held the camera down near my ankles and fired off some shots blind; this required ‘chimping,’ examining the LCD afterwards to see what I got, only necessary because I couldn’t use the viewfinder in the first place (thus, one of the few legitimate reasons to do so.) Try as he might, he still hasn’t caught me doing this, simply because I rarely ever do it. Ah well.

I got another frame that I like even more – that’ll be along soon. We’re almost done with the beach trip now.

As always, I’m on it

May 29th is Blurred Bird Day, which requires that you say it fast and never clarify it to anyone, because that’s half the fun. It should come as no surprise that, even as obscure as this holiday is, I’m fully prepared.

Kindly note that blurring the bird by failing to focus tightly does not count – it must be motion blur, preferably the bird’s.

pileated woodpecker Dryocopus pileatus moving head during exposure
Some birds are quite adept at it, of course.

great blue heron Ardea herodias moving entire body during exposure
This one probably shouldn’t count, because it’s more like an anti “Nail The Pan Day.”

It’s also not the best form for the image stabilizing function in the lens to produce the effect from its own movement during exposure.

juvenile downy woodpecker Dryobates pubescens moving head during exposure
One trick is to shoot in reduced light, but you can also close down the aperture pretty far to help lengthen that shutter speed. Too far, of course, and you’ll be moving the camera, so it takes a careful balance.

Bonus points are garnered, naturally, if you can produce something truly bizarre and just a bit unsettling.

Have fun!

Profiles of Nature 21

chimpanzee Pan troglodyte Chollum Bargarnthupi showing excellent dentition
Yes, it really has been an entire week, and so we return to our Profiles, featuring Chollum Bargarnthupi. Chollum was kidnapped and sold on the market of color as a slave model, forced to pout, look haughty, or even exuberantly ecstatic about kitchen storage (seen here) for much less than minimum going rates, required to even buy his own upper lip bleach. He escaped with the aid of a trusty scaup named Shubedu and vowed revenge, endeavoring to undercut the fees of his former captors until they folded in bankruptcy; since he’d been a slave, this meant that he now had to pay agencies for his services – there are some issues with this plan, true. Despite this (or perhaps because of it,) he has become one of the most sought-after chimp models in the business, and has pulled down countless contracts for toothpaste and dental services, becoming the de facto standard in the biz – those are stunning teeth, for a chimp. He is very sensitive about his camel-toe tongue, though, so we promised not to mention it. Chollum’s revenge plan actually started to work and was hurting the bottom-line of his former captors, resulting in the redoubling of their slave trade efforts to compete, branding him a pariah within ethical and amnesty circles; he’s now considering the rather trite multi-weaponed infiltration and destruction plan instead and has started a GoArmMe page. In his spare time he likes researching activities for his spare time. Chollum reluctantly admits that his favorite character on a standard keyboard is the one no one knows the name of.

Relations with Russian and China seem pretty mellow right now and the threat of Armageddon is slight, so we’ll be back next week! There’s a mixed blessing…
