Visibly different, part 19

pair of pileated woodpeckers Dryocopus pileatus in JN Ding Darling National Wildlife Refuge
Our opening image today comes from 1995, my first trip alone to Florida, dedicated to nature photography. I was starting to get serious about it, but was still using older Olympus equipment and print film, and this was taken with a Vivitar 75-260mm lens. I was in JN “Ding” Darling National Wildlife Refuge on Sanibel Island and lucked onto this pair of pileated woodpeckers (Dryocopus pileatus.) I was absolutely delighted, not just to photograph one for the first time, but to get a pair in such good conditions. I initially believed this to be male and female, but I now suspect, from appearance, that the one on the left is a juvenile. Pileateds are large, almost the size of crows, and have distinctive calls and habits, but they remained at least a bit secretive every place that I’d lived.

Notably, immediately after this visit, I went literally across the street to a wildlife rehab and education center, CROW (Clinic for the Rehabilitation of Wildlife) and attended a presentation that was conveniently scheduled for only a few minutes after my arrival. I was active in wildlife rehab at that point and took the opportunity to examine their facilities and efforts, including chatting with one of the presenters for a while afterwards. We did this in sight of a large outdoor cage housing a captive pileated, an adult male with an amputated wing that could not be released and thus served as a resident ambassador and conditioning assistant. The presenter there told me of the wild pileated that lived in the refuge and would come over from time to time to drum territorially on the main cage supports, driving the resident within nearly apoplectic since it could not reach the intruder on the outside of the cage to drive him off. Within minutes, I got to see this firsthand, though my camera remained in the car for some reason.

In the intervening 27 years, I’ve seen pileateds perhaps a dozen times, obtaining photographs somewhere around half that – one of the earliest posts here was about one visiting the place where I worked. It didn’t take too long before I considered the initial image up there to be pretty crappy, yet I wasn’t snagging any really decent portraits – better, surely, but not what I considered impressive.

Until last summer.

I probably don’t have any better illustration of my progress in photography than these, but let’s examine the significant changes. Equipment, surely (Olympus OM-10 with Vivitar 76-260mm versus Canon 7D with Tamron 150-600mm,) and finally getting a decent opportunity contributed hugely. At the same time, my ability to instantly recognize the calls, flight profile, and plumage as it passed in flight were major factors, as well as tracking the fleeting glimpses to realize that it had landed on the ground. And then, the careful and patient creeping forward, using treetrunks to disguise my movements multiple times, until I could get close enough to lean out slowly and fire off several frames; I wouldn’t say that this was my best accomplishment of stalking, but it certainly produced the goods. You can’t control luck, but on occasion you can control how well you exploit it.

Storytime 19

blue crab Callinectes sapidus illuminated by waterproof flashlight
Our story this week hearkens back to an ancient time and forbidden land, the stuff of legends and lore, the mystical realm of Florida in the early 2000s. I mean, c’mon, these are photos we’re talking about – how far back do you think we can go?

In this case, it’s an old (relatively) collecting location for me, the docks on the Indian River Lagoon near one of the causeways. Here, I could lie on the docks with my face hovering just above the water and survey the bottom for interesting critters, and because of the subtropical environment, I was able to find plenty, though admittedly, this particular one can be found at least halfway up the east coast. Looking to do some esoteric experiments, I decided that I’d try a nighttime long exposure by the light of a waterproof flashlight, and sought out any likely subjects. I’d done the same with some of the grass shrimp that were abundant in the area, but they’re as close to transparent as possible and thus are very hard to make out in the resulting images. But this cooperative Atlantic blue crab (Callinectes sapidus) proved to work very nicely. I simply propped the light up at the right angle on the bottom, aiming into its face (or what passes for such with a crab – you define the edges if you like) and, somehow, stabilized the camera aiming straight down into the water.

[This part is actually a small mystery to me, because I don’t remember how I did it. I have the impression that the camera was anchored on the dock, but this doesn’t seem feasible. More likely was that the tripod was planted in the shallow water, with a lateral arm holding the camera a little away from the center – I’ve had a tripod where the center post could be removed and repositioned horizontally for decades, so this isn’t a stretch, but it still had to be pretty low. I’m honestly not sure.]

Perfect clarity was not going to be achieved, partially because of suspended sediment, but mostly because I was still shooting down through the gently rippling surface, so during the time exposure there would be distortion from that; overall, however, it wasn’t too bad. And then I added a small variation.

I had a couple of little slave strobes, handy for macro work, and while they weren’t waterproof themselves, a zip bag took care of that, and I simply triggered one with the test button through the bag while I held it underwater. I’d still done the long exposure by flashlight, but the strobe added a lot more light and a bit more accurate color. It also highlighted the bubbles on the surface, which answered one question that I had, which was whether or not I’d used one of the reverse-periscopes that I’d made to get a clear view through the surface; obviously not.

And for giggles, I’ll add in another photo taken at the same docks though probably not the same evening, another long exposure, but this time a selfie – I think I took it with the intention of sending it to my mother but never printed it. The light is a combination of moonlight and a streetlamp a few dozen meters away at the parking lot, and the exposure time was probably between ten and thirty seconds, so I had to hold still – there’s a faint hint of blurring to my face that tells me I wasn’t perfect at this, but then again, this is undoubtedly for the better.

Your little reminder

Quick one here, a shot from a few weeks back, to remind you that tomorrow, May 11th, is World Migratory Bird Day, so go out to your favorite big box store and purchase yourself a brand new migratory bird. Or, perhaps, just get outside and try to spot or photograph a few, or feed some, or learn about some, or pretend you’re one and run north and south – whatever works. Once again, I’m going to be a little tied up this day, so I’m not sure what I might produce myself, and I’m not the biggest bird photographer (got about another 32 kilos to go.) But we’ll see what happens, I suppose.

Good habits and bad

So for today’s topic, let’s talk about good nature photography habits – and bad ones too.

American five-lined skink Plestiodon fasciatus male with red head on tree trunkFirst off, let me just say that in the time I’ve been doing this blog, both of the species seen here have had their scientific names changed, because I guess taxonomists get bored. Actually, I know it’s because new information regarding relation and genetics and all that is discovered and the changes are made for accuracy, but for those of us who strive to include the scientific names, it does get rather taxing (Ha! Did you catch that? Taxing. Taxonomy. Why am I withering away here when there are all these comedy clubs begging for such talent?) The fellow at top (the one out of focus – I’m being fartsy again) is still an American toad, but now known as an Anaxyrus americanus rather than a Bufo americanus, while the embarrassed dude at right, an Amercian five-lined skink, went from being an Eumeces fasciatus to a Plestiodon fasciatus. Yes, a dude – the red head denotes a male. But notice, they’re both specifically ‘American’ species. What do you wanna bet it’s those Europeans who are provoking these changes?

All of that has nothing to do with habits, however, so let’s get back on track, people. Nearly everyone knows that nature photography takes sharp eyes, but hearing is also important too, especially being alert to the sounds that aren’t typical. Both of these critters were photographed on a recent outing not because I spotted them, but because I heard them as they darted for cover. Neither was particularly loud either – both times the sounds were the faint rustle of leaves as I approached. By looking immediately down at the sounds as they occurred, I caught the flash of movement which pinpointed their position even as they stopped moving to count on their camouflage.

The other example of this came up several times today, once even as I was writing this post. The windows are open, and scatterings of birdsong can be heard at just about any time, including the mad demands of fledglings from the nest box just outside the window. But at times, the bird calls would get frantic and quite close, with several different species taking part, most noticeably the sharp chirp of the robin’s alarm call. This prompted me to go out armed with the long lens. After this failed to be of any use, I attached a camera to it.

I got several glimpses without enough to identify it, but the protective songbirds kept pinpointing its location, and I finally got a good enough view to peg it as a red-shouldered hawk (Buteo lineatus.) This was no surprise, since I’ve seen them countless times in the area and hear their territorial calls often, a repeating cry that sounds rather forlorn. But the way it was staying down low and cutting between houses, I was suspecting a bird-hunting accipiter, like a Cooper’s or sharpshinned hawk. It’s also a good habit to know what the local species are like, where they live, how they behave, and so on – this can (sometimes, anyway) help establish what you might be seeing.

I have been working on a small pond in the backyard, partially ornamental, partially to attract photo subjects. It’s far from done, but I’ve placed the pond liner and filled it with water to get it settled in place, adding a filter to help control its use as a mosquito breeding ground. A few days back, I was made aware that it was already serving its purpose when I heard a loud plop as I approached, quickly determining that we now had a resident frog – I took it to be a leopard frog at first, but the markings indicate that it’s a green frog instead. I think it’s going to be one of those days – green frogs used to be Rana clamitans, but are now Lithobates clamitans

Within a day or so, I determined that we had two, one of which was exceedingly mellow and would often sit at the pond’s edge without moving, even as I did yard work very close by, or when I moved in for a tight portrait. Such habits can be very helpful to nature photographers, but aren’t exactly the kind of trait that any wildlife should develop. You see, one of the dietary staples of a red-shouldered hawk is frogs…

green frog Lithobates clamitans being far too mellow
In fact, I first heard the frenetic alarm calls of the local birds yesterday, and went out onto the back porch to see the hawk take off from the ground right near the pond, clutching something. It looked bigger than this frog, but then again, I haven’t seen it since. But now the hawk has been doing a lot of flying around at low level within the tree canopy of the immediate area, so I think that, in a rather indirect way, I fostered this behavior of the hawk. We have three occupied nest boxes on this property alone, two titmouse and one chickadee nest, and who knows how many robin’s nests up higher; none of them are happy with this development themselves, since red-shouldered hawks will also eat baby birds.

So now, on to my bad habits.

Al Bugg and black rat snake Pantherophis obsoletaOn an excursion to the river the other day with the unimpeachable Al Bugg, one of the things I was keeping an eye out for, again, were the snakes. Surprisingly, we’d been out for a couple of hours before I spotted a 1.5 meter black rat snake (Elaphe obsoletano, goddammit, it’s now a Pantherophis obsoleta. I mean, come on!) Now, I know wildlife should be left alone and not disturbed, but I’m rather bad about snakes; if I can capture them, I often will, just to examine them, and will take any given opportunity to demonstrate to anyone who should be around that few species present the faintest danger. If they appear to have eaten recently, or are engaged in amorous pursuits or things of that nature, I’ll leave them be, but if there seems little chance of interrupting them during crucial times I often won’t hesitate. The rat snake was quite mellow, as they often are, and made no attempt to bite, so we did a quick photo opportunity. And yes, I’m working on getting Mr. Bugg to dress more appropriately for stalking wildlife – he’s a UNC fan and often wishes to make this unmistakable.

It wasn’t the rat snakes that I was expecting to find, especially not swimming along the rocks even though they’re perfectly comfortable with this, but the water snakes instead. We’d spotted a small queen snake (Regina septemvittata) early on, but I was after the more impressive species. Eventually, I came across one sprawled among the rocks in a rather obtrusive way. Once again, not a good habit here – too far from protective water and a very inviting target for hawks and herons.

Once again, this is a northern water snake (Nerodia sipedon – still,) not quite a meter long; not huge but certainly noticeable. I was able to lean in pretty close without it getting spooked, which was a bit curious given how fast the ones at the closest pond will hurtle away before I can even see their heads.

This one didn’t quite let me get close enough to do a self-portrait in the reflection within the eye, but not far from it either, and it was certainly aware of my presence. Eventually it decided discretion might be a good thing after all, and it made quickly for the water – as quickly as it could, being four meters or so away among the rocks, anyway. We watched, and it swam straight out completely across the river, probably about eight or nine meters at that point. We moved on.

same northern water snake Nerodia sipedon in almost the same locationOn the return leg a half-hour later, I pointed out the spot as we passed it, and was asked if we would see the same snake. My answer was negative, because we’d spooked it enough to make it think the area was hazardous, and besides it had crossed over. So much for my behavioral predictions. This was waiting about three meters from where we’d had the first encounter.

I’ve compared several of the markings in the photographs and am quite sure it was the exact same one, not to mention that it still had that brightness from being damp. This time around, I was able to block it off from escaping, and picked it up, not quite getting the grip right behind the head that I’d wanted to, at least at first.

Author holding northern water snake Nerodia sipedonMy grip is not half as fierce as this photo makes it seem – basically, firm enough to prevent it from escaping but not even enough to prevent it from squirming. I mentioned before that this species is aggressive, and because I didn’t initially grab it where I should’ve, it was able to demonstrate this trait nicely, biting me three times as well as smearing my forearm with feces (a very common defensive act of snakes, as well as a few other species.) Snake teeth are sharp but ridiculously short, only used for gripping in the non-venomous species, so there was blood as proof, but that’s about all. Snake shit, on the other hand, has a very distinctive odor and does not go away easily, so I received the benefit of that until I got home.

People always ask, “Are you sure it’s not poisonous?” Yes, I’m sure. The markings are not even close to a copperhead, and those stripes along the lower jaw (seen very well above) distinguish it from a cottonmouth – which aren’t found much in this area at all (like, only once confirmed.) Those are the only two venomous (not poisonous) snakes in this region. Moreover, the habitat is what water snakes prefer, which includes the cottonmouth, but not at all what copperheads prefer; another aspect is simply knowing what is likely to be found in any given terrain. I think everyone should see examples of the local species early on, especially side-by-side if possible, so they feel comfortable telling them apart. There are far too many overboard reactions to snakes around here, especially considering the trivial risk – dicking around with your toy phone in the car is hundreds of times more dangerous.

trivial bite injury from northern water snake Nerodion sipedonUnfortunately, the autofocus wandered to the background on Mr. Bugg for this shot, and he didn’t get any others for security, so the detail is lacking here, but you’re seeing the horrendous damage to my hands from the bites. Actually, you can only see one, the slow-oozing blood on the middle finger of the right hand; there’s another bite on the base of the left thumb, which is why I’m holding my hands close together like that, but with the focus off you can’t even make out the tiny red spots. I did more damage to myself working in the yard earlier. In other words, big fat hairy deal, and this was with a provoked bite. Had I not grabbed it, it might have happened only if I’d stepped on it instead.

As for my interruption of its ‘natural’ behavior or whatever? First of all, humans are as natural as hawks, so any distinctions in such a topic are arbitrary, period. Second, considering the large number of people that would kill it, throw rocks at it, let their fucking unleashed dogs at it, and so on, we’re not talking serious impact from handling. And then there’s getting eaten by hawks, which is frequent and typical. If I convinced this one to be a little less blasé about where it sits and how close an approach it permits, that could very well be all for the better. Judge me as you wish.

A year goes by fast

Last year about this time, I published a post about my little friends the fishing spiders, whom I call ‘friends’ not because we hang out and hammer down Pepsi together, but because my first photo sale featured one as a subject. Lately, a few have been making themselves obvious, clearly begging to be featured again, so who am I to crush their little spirits? And I say with all honesty, it’s not that I’m avoiding bunny rabbits and ducklings, it’s that I simply have not seen anything cute at all. But still, I know some people don’t want to be greeted with spiders all the time, so I’m including the detailed pics below the break.

A little over a week ago, while staging the photo for the previous post, I espied something that can occasionally be found at the edges of ponds and streams that have plenty of reeds, seen to the left: the molted exoskeleton of a fishing spider. Spiders, and most insects, shed their ‘skins’ as they grow larger, splitting the chitin and squeezing out backwards, and then usually hiding for a while since their new exoskeleton is soft, leaving them much more vulnerable to predators. The translucent molt is left attached to whatever surface was handy, usually mistaken for a dead insect, but it’s instead a clue to be watching for the former owner nearby. When I sat down to take this image, I soon spotted the culprit hiding in the tall grasses. With a stick, I carefully flushed him out, whereupon he panicked and scampered for cover practically underneath me, but then froze and held perfectly still for some really tight closeups.

On composition, part eight: Clean fill wanted

So now, let’s talk about another aspect of controlling your photography – well, actually, I’ll “talk,” you’ll “listen.” That’s how a blog works, unless of course you actually decide to comment (you are more than welcome to, you know.)

Anyway, the impression of many people is that nature photography means taking things as they are, capturing only what exists, rather than, for instance, staging an image. But there are many techniques available to control your image, without actually involving staged circumstances, and one of them is lighting.


Natural light can be very useful, and it is perhaps the best thing to use to have your backgrounds showing up cleanly, but it’s arbitrary and capricious – haze and overcast change the colors of your image, as will ambient light reflected from nearby foliage or surfaces, and light levels don’t always allow you to capture the action (or even hold the camera still enough.) Too little light, and your shutter speed has to drag out to let enough in for a proper exposure, and there’s too much chance you will twitch the camera or your subject will move – these are the number one causes of blur and softness in photos. And the contrast may not work to your liking. My treefrog subject here is docile enough to let me both use the tripod, and play around a bit with options.


So the first option is to use a flash or strobe, getting adequate light onto your subject, color-balanced, and perhaps even from the direction that you want. But it is often harsh and very high contrast, which photography only increases – both film and digital almost always appear higher in contrast than our eyes see. This makes colors “pop,” but it also increases shadows and may drastically change your image. These images were taken only seconds apart, but as you can see, either night fell with extraordinary speed, or something funny happened with the light.

What was funny is that, even though both images used an aperture of f16 to maintain a certain depth in detail, one was done with natural light using a very slow shutter speed, and the other with a flash (and softbox) at 1/200 second shutter speed. The top one allowed the low light in the background to come through, the bottom one relied entirely on the flash – the background light was too sparse to even show up in the exposure. Yet, the detail from the frog isn’t necessarily better, most especially because the shadows that were introduced hide the eyes and make things a bit harsher. Enter the sneaky little trick of most serious photographers: the fill lighting.

Even see a model shoot, where photographers’ assistants are running around with large reflective panels or adjusting multiple light sources? These are used to balance the light levels in the shadows, so the shadows don’t become too dark and detract from the image, like my example above. It’s call fill lighting, and it’s always dimmer than the main lighting and usually from an opposing direction, giving soft illumination where the main lighting does not reach, yet not detracting from the impression of a single, perhaps natural, light source.


Now we can compare the difference. Look at the eyes, and the shadows on the bark – even at the highlighted sections of the frog’s shoulder. Far less harshness, less idea of a flash being used (also helped by the diffuser on the softbox,) and the eye becomes visible, which is good because we always look to the eyes. A little fill can help quite a bit, but there’s still the idea of the frog hiding under the leaf, and the eye becomes much more effective being almost hidden rather than completely invisible.

Fill lighting can also be accomplished using natural light, such as bright sunlight, as your main light source, and the camera strobe for the fill. A camera strobe is never a match for the light the sun puts out, but it can be sufficient to soften the shadows and throw a little light into hidden areas, like the first photo here. If you find yourself even doing casual portraiture in brighter sunlight, try firing off the flash – you may like the results a lot more, and get rid of some of the contrast and dark shadows.

Ideally, fill lighting should be accomplished by measuring light levels and using a variable light source, whether it’s an adjustable strobe or having your assistant angle the reflector differently. But such luxuries are rarely available to the nature photographer (the subject may not hang around for much in the way of shenanigans,) and there’s only so much equipment you may want to carry anyway – I know I have my limits. But in a pinch, you can make do with materials at hand. White surfaces will bounce a certain amount of light, aluminum foil and similar materials a bit more. Finding myself in need of the reflection and not having anything other than the camera and softboxed strobe, I cheated. One of those little pieces of plastic in my wallet turned out to be useful for something after all, when the white back, held just out of view, could be used to bounce some of the strobe’s light back into the underside of the frog. Here, you can see my fingertips intruding into the frame.

You may like any one of these images better than the others, and that’s fine – opinions vary, and your own artistic expression is part of your style. But if you’re planning on selling images, bear in mind that editors have their own goals for illustration, their own stories to accompany. The “daylight” shot is nice, but a bit low contrast and green, and treefrogs are primarily active at night, so the “night” shots have their own uses. Get a variety of images, and yes, more angles than I’ve shown here (which I did indeed get myself, I just stuck to a particular point for this post.)
