Don’t expect much

Yes, I’m aware of the total lunar eclipse due to take place in a few hours, and I am intending to pursue it (again.) However, Old Man Weather may have other ideas.

This is what it looks like out there right now, and it’s been this way for hours. It may still clear up a bit more, but if it remains like this, I’m not going to get anything worthwhile. I’ve gotten plenty before, so no biggie, but naturally this eclipse will be the one where a major asteroid crashes into the near lunar surface and makes a spectacular display.

I have to fess up that my shooting angle for this one could have stood improvement:

branches interfering with view of hazy moon
Really, I just stepped out onto the porch for a couple quick example frames – you’re lucky I even used a tripod. I’ll do better if the skies do better.

Been building

This has been a while in the making, as will become evident, but it worked.

male and female wood duck Aix sponsa in small open water patch on pond during freezing rain storm
Most of the pics are old, because I was trying to accomplish a few things first, and so we see a pair of the wood ducks (Aix sponsa) hanging out on the pond back when it was nearly frozen, during the sleet and freezing rain storm last month. We’d already been distributing corn for the Canada geese, which the ducks had also discovered, and so they were starting to make routine visits to feed. We’ll go in a little closer to see that it was still raining as I took this:

There was only one section of the upper pond that remained open water after the storm, but the ducks navigated through that to the edge and then simply climbed onto the ice to walk the rest of the way to the yard, though we were being helpful in throwing corn out onto the ice as well.

Here, the break in the terrain behind the male’s head marks the edge of land, with the frozen pond just beyond it, while I somehow got out far enough for a clear shot without spooking off the ducks, which has been exceptionally tricky.

Yet I was still having difficulty nailing sharp focus and achieving a decent portrait, not helped by the lower light levels slowing the shutter speed down. Meanwhile, the ducks soon developed the habit of descending on the yard en masse at least once a day, usually twice, with their numbers steadily growing as the word got out. Yet while the geese and mallards began getting habituated to us quite readily and would approach within a few meters, the wood ducks wanted nothing to do with humans and would fly off at the merest hint that we were out and about. Attempts to photograph them from an upstairs window were often thwarted by them hearing or seeing the window opening – they have both excellent vision and hearing. But there was no way that we could watch an entire flock of them coming way up into the backyard without finding some way of capturing this. And eventually, it worked out.

What’s funny is, I tried a couple of different remote security cameras aimed from a good location, but the nature of those is that the wider viewing angle defeats the resolution, and so you can tell there’s something there, but not see it too clearly. Worse, the motion sensing function of the better of the two still couldn’t trigger on the ducks; too small in the frame and not enough contrast. So that meant that we’d have to start recording manually when we actually saw them out there. But while we were still trying to do this successfully, I managed to sneak upstairs to the window that I’d left open and finally get the footage that I was after.

A pair has been seen a couple of times hanging out at the end of the pond where the nest box is – we think it’s the mellow pair that doesn’t spook as easily as the others. Now, we’ve already seen mating behavior from the mallards, but not yet from the wood ducks, so it’s not clear yet whether the nest box will be used this year – we’re holding our breaths.

Meanwhile, I fretted mildly, when moving away from the previous area, that I might have no opportunity to photograph the bald eagles like we’d been doing down at Jordan Lake, and while I have spotted a solitary example here, there hasn’t yet been any indication of regular activity. But if I have to replace them with waterfowl like this, especially right in the backyard, I can probably cope.

No numbers this time

I get a little tired of numbered posts, even though I’ve been the one that established them in the first initial place, and we had a ‘Sorting Finds’ post just two weeks ago. But in that intervening time, I collected over 700 more images before I even got the chance to back up the files to an external drive (I have two internal harddrives mostly for backups, and a backup server that’s been down for a while, but then a couple of old harddrives that I use for the same purpose,) so it was time to do another sort, and indeed, it produced a few images that escaped posts back then. You know, all two weeks ago or less.

This is the one that I’m a little surprised to find that I missed, but then I recall that I was hoping for a better followup.

North American beaver Castor canadensis departing through channel
I looked out back one midday and discovered a North American beaver (Castor canadensis) cleaning itself on one of the small tree islands, quite close to the house – both the time and the location were curious, since they’re largely nocturnal and have only left vague evidence that they even visit this portion of the pond at all; I’ve only seen them in the creek off the back of the property, though the evidence of their visits, in the form of gnawed-off saplings and stripped sticks, is found occasionally. I tried slipping out the back door with the camera, shielded from view by a large tree trunk, but apparently it heard me because it was gone when I eased into view. I briefly spotted it making its way out through the channel between the upper and lower ponds and got off a single frame.

Now, I’m not 100% sure this is a beaver, since I’ve seen a nutria on the farther portion of the lower pond when visiting with a neighbor. Nutria tend to be slimmer and smaller on average, but their physique overlaps with beavers at the larger end, and the only other way to tell at a distance is by seeing their ratlike tail, which I never got a glimpse of. Still, I found a beaver stick in the pond not far from where I’d spotted this guy (nutria eat grasses,) so I’m leaning towards beaver.

Just because I captured the two together, I feature this wood duck (Aix sponsa) cruising past a yellow-bellied slider (Trachemys scripta scripta) in the pond. Not quite the lighting conditions that I would have preferred, but I’ll take it for now.

And more on the duck front.

female mallard Anas platyrhynchos preening under highly raised leg
Here we have a female mallard (Anas platyrhynchos) industriously preening herself – I realized during sorting how high her left leg was raised. And this did not escape the attention of the male either:

It’s not nice to stare, but she can’t possibly see him so it’s okay. And it’s her fault for doing that in public anyway. If I had a readership, I would have just lost half of them with that comment, but I probably don’t have a readership because of various such comments in the past. Though I’m not the one staring, you know…

[These images illustrate something that may pose a problem pretty soon: there are lots of intervening small trees and such on the edge of the pond, devoid of leaves now, but not for long, and my view of pond life is going to get much worse. I could always go cut them all down, but I’m trying not to do any more than is necessary, and this spring and summer are going to be the acid test. I’ve also already seen how glutted the surface gets with pond lilies and duckweed and so on, and I’m not even sure the ducks will keep visiting once they get fully established. We’ll see I guess.]

Estate Find X

Olympus VN-8100PC digital voice recorder and Azden SGM-2X unidirectional microphone with 'dead cat' wind guardNo images for this one, because it’s been a slower week and all of the photos that I’ve gotten are subjects that have been featured before. So it’s strictly audio this time – well, and my typical exposition. These are all night recordings, which should become obvious, and all recorded right from the backyard. I was using an Azden SGM-2X unidirectional shotgun mic with a wind guard on an Olympus VN-8100PC audio recorder, since I’ve never splurged (yet) for a higher-end recorder. All clips had a little noise reduction done to cut down the normal background hiss, and one was amplified a little, but for all, I’d recommend headphones.

First up, we have a few different frog species inhabiting the pond.

They think it’s spring

If you noticed a trickling sound in the latter half of the recording, that was the rain starting as I stood on the edge of the pond – there isn’t enough flow to produce the noise of running water. Meanwhile, we have the sharp peeps of the spring peepers (Pseudacris crucifer,) the deeper short sounds of what is likely a southern leopard frog (Lithobates sphenocephalus,) and the background mutter, heard before, that is a toss-up between Atlantic coast leopard frogs (Lithobates kauffeldi) and wood frogs (Lithobates sylvaticus) – with such a chorus of them in the middle distance, it’s hard to tell if any single frog is repeating or not. You can find the specific calls of these at this page.

On another night, we had a slightly different set of sounds.

Probably not a cougar

Up front, the drawn-out creaking growl is likely a gopher frog (Lithobates capito,) but now some of the muttering, duck-like calls can be heard individually, repeating a few times – these lend weight to being wood frogs. Note that I have never seen either a gopher frog or a wood frog – these identifications are made only by the calls, but I’ll be trying to remedy that soon enough. All but a couple of these seemed to emanate from the far side of the pond, which is marshy and soft, so getting up close and spotting them might be tricky, more so by the headlamp, though we’ll see what happens.

One day while observing the wood ducks, I witnessed a male appearing to lead a few others around with very faint peeping calls, and right at dusk one night, I could have sworn I heard that from the upper end of the pond near the nest box. If correct, this would mean that they’re actually roosting on the nearby portion of the pond rather than down through the channel on the lower bayou where they always seemed to disappear. So the following night, I went out with the audio recorder and got no ducks, just the same ol’ frogs, but then a fierce wind suddenly roared up.

Came up abruptly

When the volume jumps in the middle, that’s when I turned and aimed the mic into the trees, and yes, you hear a branch snap off and hit the ground, while something else hits the metal roof over the AC units. I could see the treetops swaying wildly against the night sky, and could only estimate the windspeed, but it was a sudden squall type of gusting, on a night when no serious weather was predicted. Much credit to the ‘dead cat’ wind guard on the mic, because no thumping or rumbling of any kind can be heard, so a great test; I’d had to make this one myself because I couldn’t find one long enough for the Azden SGM-2X (it’s actually some faux-fur scarfy thing from Temu, with the backing removed, folded and stitched into a tube.)

And lastly, we have this capture, that I’ve finally been lucky enough to get.

No, we don’t live by a rainforest

Those, all of them (well, except for the frog croaking and background traffic,) are barred owls (Strix varia) – those are the sounds they make as mated pairs. I’ve been hearing the calls semi-regularly since we moved in though I have yet to catch even a glimpse of one around here. I had to amplify this recording a little, but likely not because of great distance – barred owls have a faint and echo-ey call that makes them sound twice as far away as they actually are, so if you hear them clearly, they’re generally within 50 meters. My guess is this pair was in the vicinity of the stream on the back side of the property across the pond (where the beaver lodge is.)

Man, spring is going to be off the hook.

Still with the ego

A couple weekends back, The Girlfriend and I were checking out thrift stores in another town and came across a nice little wood duck figurine, fully painted. It became clear that the proprietor wanted much more for it than we were willing to pay, but it got me mildly determined, and of course when you have a 3D printer you have to check out the options. Sure enough, someone named milletro had a wood duck decoy on Thingiverse, apparently a 3D scan of an actual decoy, and I downloaded and printed it.

3D printed models of wood ducks Aix sponsa, original in front and author's remix in backBut the proportions were off a bit, the head being too small and narrow, as well as too rounded on top – real wood ducks have rather oblong heads. So I reworked the model in Blender, a 3D modeling software – this was no small feat, because I don’t know how to do complex shapes very well, and so resizing and reshaping the head left behind some yucky artifacts. After I printed it, I had to do a little sanding, but at least the proportions seemed a lot closer to reality.

[Original model in front, my rework in back.]

four images of painted 3D printed wood duck figurine by the authorThen, of course, I had to paint it. Interesting enough from the standpoint of mixing colors to try for the best match, and the details of the real ducks have a bit of variation – not in their coloration so much, but in how the details look depending on whether the neck is more extended or not, and how the wings sit across the back, and so on. This says nothing whatsoever of the iridescent feathers, which I had no decent way of emulating to any degree of accuracy – they do make iridescent paints, but they’re expensive and I’m not sure the effect is the same as wood duck feathers anyway. After several tries, I settled on a base coat of a metallic grey, overcoated with clear acrylic mixed with green or purple, which provided a colored sheen anyway. I mean, the actual bird feathers change color depending on the angle that you’re looking at them, as well as disappearing and simply appearing black in indirect light, but this was close enough to communicate the idea anyway. At least, I think so…

The original paints that I used were matte, so I top-coated with a clear gloss acrylic, because duck feathers are waterproof of course, but I think it has a little too much shine to it and may have to re-coat it in semi-gloss, except for the eyes and iridescent feathers. The model itself is roughly 150mm in length, or about half life-size of the real thing – good size for a shelf, you know? Plus it kept the print time down to about two and a half hours. I’m pleased with the results, even when I see the small printing and painting mistakes that I made. And, of course, the new version was uploaded to my Thingiverse account.

[A small note: Licenses and attributions are a variable thing, though most people uploading designs to such sites do so under a ‘Creative Commons – Attribution’ standard. This means editing their designs is allowed, as long as you credit the originator, but commercial usage and sales are not allowed without express permission. There are still assholes that violate this – I’ve seen them a few times myself – but for the most part, the agreement is honored as part of the 3D printing community, and that’s how I was able to use and edit this one. Without mmilletro’s original, I would have made no progress at all because I simply can’t model shapes of this nature.]

More photos of the real things will be along shortly, even though I’m still trying to get a really nice portrait. They’re now visiting the yard routinely because we’re feeding them, but they’re still insanely wary of our presence and usually at least swim off, if not flying away to the lower pond, the moment they see us, so nearly all observations have been taking place through windows. Working on it…

male wood duck Aix sponsa venturing out into sunlight

Tricksy tricksy

I left you hanging with yesterday’s end-of-month abstract, so I am making good on it and revealing just what it was now. This is almost disorienting to me, because the weather has changed drastically since it was taken and it really wasn’t that long ago, after the sleet and freezing rain. So let’s take a look at the original.

sunlight glinting off of the surface after a sleet and freezing rain storm
Note, first, that letting the camera meter off of the bright white sunlit surface was enough to darken the frame down significantly (because camera meters are set to render a middle tone and don’t ‘know’ that what they’re reading from should be white,) and I purposefully darkened it another 2/3 stop to enhance the contrast. As much as it looks like snow, this is actually the crunchy surface left behind by a sleet storm that turned into freezing rain, so a bit coarser and rougher than snow. Perhaps a bit more reflective, too, but at certain angles, the rainbow glittering of tiny reflections was evident, and that’s what I aimed to capture.

But then, I wondered about enhancing those sparkles, and started playing with the Curves function in GIMP.

screenshot of Curves function in GIMP showing setting and effect
What this shows is how all but the brightest registers were reduced significantly, and luckily, all those sparkles were much brighter than the icefield. The normal ‘curve’ would be a diagonal line across the middle of that histogram, lower left to upper right, but here it’s bowed down significantly, and you can see from the underlying grey mountain peak in the graph that most of the image was centered on the middle tones. When they were reduced, the sparkles could be seen much easier. Simple!

What did it really look like, in person? Well, something about like this:

corrected version of glittering reflections off of frozen sleet field
… except that I can’t render it more accurately here, because there’s no way to make the glittering reflections almost blinding in nature; the dynamic range of digital images and the monitors that display them is much, much smaller than what happens in real life, and until we have monitors that could make you squint and see spots afterwards, this is as close as we’ll get. I am kind of puzzled by this, though – with all of the advancements that have been made in displays and LCDs and all that, increasing the dynamic range, the gamut of brightness from their version of ‘pure black’ through ‘staring into the sun white,’ hasn’t really occurred. I’ve been waiting for this for a long time.

Meanwhile, how come nobody has designed glass that simply filters out all light that passes a certain brightness? You could be driving, and the low winter sun through the trees or that nasty reflection from someone’s rear window is simply rendered as black, or at least a hell of a lot darker. Just selective polarization from intense light. There must be a way to do this…

Rehab x 7

It’s time to talk about wildlife rehabilitation, since this has now become an annual thing, and with good reason: we’re entering the season where this has the most relevance, and the highest likelihood of being beneficial to someone out there. This was all written years ago, but still applies quite well, so without further introduction, let’s talk about injured and orphaned wildlife.

I used to work in this field a fair amount, both in administration of wildlife organizations and as an active raptor [birds of prey] rehabilitator, plus I served as wildlife adviser in several different situations. So I’m familiar with most of the more common reactions people have when they find ‘orphaned,’ injured, and ill wildlife. It’s hard to give enough useful information without trying to cover every situation or alternative, so treat this as an overview. One thing that I especially want to emphasize here is that there is an immediate emotional response in most cases, which tries to override the advice given by those who work in the fields, so be aware of it. There isn’t an ‘instinct’ we might have that applies to wildlife, and the rational mind is the part that needs to take control.

Additionally, the amount of folklore regarding wildlife is not just abundant, in most cases it’s ridiculously wrong. I’m not even going to say, “If in doubt…,” because you should doubt right off the bat, and consider that most of what you’ve heard is highly suspect. This means, contact someone who is supposed to know, and go with their advice.

Number one rule, and I can’t repeat this enough: Don’t try to raise wildlife on your own. Their diets are specialized, their needs varied and specific to the species, and their adult behavior dependent on how they’re raised. This isn’t the place for guesswork or experimentation. Even if they seem to be ‘doing well’ (like the viral video of the guy raising a baby hummingbird,) they may have developmental issues from an improper diet or exercise, or simply have imprinted on the wrong species, and you are in essence just prolonging the death of the animal. In the US, it’s illegal to raise any species without a specific permit, and songbirds are federally protected. It’s possible to obtain these permits, and quite frankly encouraged, because there are few places with enough rehabbers, but if you’re going to do it, do it right. More further down.

So, we’re about to enter baby bird season, and this accounts for a large percentage of wildlife encounters. I’ll dispel the first myth that touching a baby bird will cause the mother to abandon it. Utter hogwash, pure and simple – yet, I don’t always discourage parents from teaching this to their children, because it’s one way to try and get kids to leave them alone, which is a good thing. Better, perhaps, to teach them to leave them alone for the right reasons, which is to avoid interrupting their feeding schedule, or injuring them, or thinking it would be neat to have a pet robin. But returning to the myth, baby birds will occasionally fall from the nest, and it’s perfectly fine to return them to it, and in fact this is recommended.

It doesn’t always work, however. Some species will discard young that are not doing well, and some even kick their own siblings out – this is nature’s method of selecting the most viable offspring, as ruthless as we find it, and we’re not going to change it. Basically, if it’s a baby bird not ready to leave the nest (not fledged; we’ll return to this,) put it back. If it keeps coming out, there may not be much you can do.

Can’t reach the nest? Try to find a way, first. If that’s not possible, occasionally the parents will accept a substitute nest, such as a plastic berry basket with soft tissue as bedding – this should be placed as close as possible to the original nest, firmly anchored so it doesn’t come down. Observe the nest carefully, but from a safe distance, for 30-60 minutes to see if the parents have indeed found the substitute. If not, seek out a rehabilitator or wildlife official.

Abandoned nest? Maybe, maybe not. Once the eggs hatch, the parent birds go into feeding mode, gathering food constantly during daylight hours and stopping at the nest for brief periods to jam it down the gullets of their ravenous progeny. The 30-60 minute rule above is because waiting less may mean you’ve simply missed the brief feeding period between the extended gathering periods. Observation has to be done at a distance that does not alarm the parents – minimum is six meters (yards,) and more is recommended. Also, being low key is paramount, so take a seat (with binoculars, for preference) and remain still and quiet. Yes, it’s boring, but it’s for the health of the offspring, and if you didn’t care about that you wouldn’t be reading ;-)

fledglingsAs the nestlings become fledglings, they abandon the nest on their own in learning how to fly. This does mean that they’ll be found unable to fly, fluttering around at low level and even just sitting there staring at you. This is normal, and they should remain undisturbed. The parents are nearby, providing food and encouraging the flight attempts. Most bird species know enough not to give away their progeny’s locations to predators, or draw attention to themselves by moving a lot, so your ability to approach, or not being attacked by angry parents when you do so, means nothing at all. Again, observation is good here, as is knowing the calls of the species in question – the parents may be coaching their young towards them.

Now, telling the difference in ‘nestlings’ and ‘fledglings.’ A nestling is a baby bird that must remain in the nest for a while; they will have few feathers, or perhaps even odd ‘quills,’ which is what the feathers look like as they are growing out. Unable to support itself? Eyes not open? Nestling. Fledglings are the babies that are ready to learn how to fly. Their feathers will have good coverage with little to no stragglers or ‘stuffing coming out’ (the baby down.) One rule I always used over the phone was to ask if there were tail feathers – if there are, they’re about ready to fly. These are fledglings and should only be observed.

If in doubt, contact a rehabber/official. This is before doing anything else, save for getting it out of immediate danger. No food, no water, nothing at all. I can’t tell you the number of times I’ve heard people say, “We’ve tried giving it water and worms” – birds can aspirate the water if it’s not given the way the parents do (you’ve noticed the beak getting jammed halfway down the throat, right?) and only one species in North America eats earthworms. Again, folklore – ignore it and be safe.

Also, bleeding in birds is serious, no matter what. Birds have very thin blood that doesn’t coagulate easily, and they can bleed out quickly. Also note that those ‘quills’ of new feathers mentioned above have a blood supply for a while, and these can be broken and start bleeding as well. Time is important in such situations.

HappyOwletBaby raptors will tear you up – they know how to use the beak and talons very early (often on their siblings) and will not hesitate to protect themselves. And adult raptors will protect their young. This is where it’s best to leave it to the experienced.

And it may seem funny to have to say this, but baby birds do not look like their parents. Adult kestrels and screech owls, both diminutive raptors, are often considered “babies” when found by those not familiar with what a real juvenile looks like. Basic rule: if it has a smooth appearance and good coverage of feathers, it’s at least fledgling age, probably older.

What about mammals? This is a little different – mammals are generally not found away from their parents unless something has gone wrong. Most especially, if the youngster’s eyes aren’t open, they’re wet from the rain or dew, or if they’re cold or dehydrated, this is the time to contact someone. Test for dehydration by gently pinching up the skin over the shoulders or side in a ‘tent’ and releasing – if the skin takes more than a second to go back into position, this is dehydration.

Always use gloves. Juvenile mammals can certainly bite, and there’s an additional risk to this: rabies is active throughout much of North America. This is an invariably fatal disease once it passes a certain point (much more so than HIV,) so this needs to be taken seriously. It is not just the bite that can transmit it, but contact of an infected animal’s saliva with mucous membranes can introduce it as well, which means that picking up a damp animal and rubbing your eyes puts you at risk. Animals do not have to be showing symptoms to be infectious, and symptoms vary anyway. BE SAFE.

It’s not just rabies. Mammals are far more likely to introduce other zoonotic issues than birds – they’re enough like us that parasites (internal and external) and some viruses can be transmitted to us. Bringing them into the house may mean you just introduced fleas, lice, giardia, and so on into your home. You’ve been warned.

possumpeepingAlso, and it pains me to have to always say this, but cute does not mean safe. Any animal can defend itself. I have never been bitten by a raccoon, despite their aggressiveness, but I have a scar and a touch of nerve damage from a grey squirrel – one, moreover, that was raised in a house. Rabbits and mice can bite the hell out of you. Shrews even have a toxic saliva. Yes, I am trying to scare you – if you’re scared, you’re cautious, which is better than incautious.

In many cases, mammals about half of the adult size can be on their own without issues – they learn how to forage for their own food reasonably quickly. Again, the stillness thing doesn’t mean they’re lost – it may simply mean they’re trying not to attract attention. This is especially so for white-tailed deer fawns – they often curl up in the grass and conserve energy while mom forages, and will not move even when someone approaches – occasionally not even when picked up. Leave them be, and come back in a few hours. If they’re still there, that’s when you should contact someone.

Rabbits are notorious for abandoning the nest if it’s been disturbed, even with a full brood of young within. This is doubly hazardous because their nests are often in clumps of grass and can be inadvertently discovered by cleaning the yard. If it happens, immediately put everything back as it was, without touching the young, and place a few distinctive blades of grass across the nest opening (preferably something you can see from at least a short distance away,) then leave it entirely alone. Come back in a few hours and check to see if the grass has been moved. If it has, things are probably okay. If not, it may be time to check the warmth and hydration of the young. Contact a rehabilitator.

Again, trying to raise them yourself puts them at a high risk. This is especially true for rabbits, which are among the hardest mammals to raise in North America. I can’t count the number of people who have assured me that they did it once before, so “they know how to do it.” While this may be true, it ignores numerous things, such as how viable the released offspring were and whether they lasted longer than a month, whether they had developmental deficiencies because of improper nutrition, and even whether they had habituated to food or behavior that left them ill-prepared for their conditions. There is a shortage of rehabilitators, so believe me, if it was easy most people would be encouraged to tackle this on their own. The fact that not only is it discouraged, it is unlawful in most areas, should be a good indication that there’s something more to consider. And the welfare of the animal should take higher precedence than anyone’s ego.

Injured animals are extra dangerous. Yes, they may seem incapacitated or helpless, but you know what they say about appearances. One of my colleagues rashly checked an injured, near-comatose squirrel bare-handed, and it bit through her finger, joining its teeth together in the fleshy part of her index finger – I actually heard them grinding together. It then passed out without letting go. Animals in pain (even pets) often respond aggressively – they have no concept of your attempts to help them, and restraint can make them even more agitated. Deer can do vast amounts of damage by thrashing with their hooves, and the big waterfowl like herons and cranes can drive that beak into your face (and yes, they aim for effectiveness.) I really want to emphasize this, because the nurturing instincts are badly misplaced here, and extreme caution is necessary instead.

“There’s a nest of animals in my attic/crawlspace/walls and they need to be removed!” No. Most especially not when they’re raising young, which is most often when anyone notices them. Once the young are there, no further damage is going to be done to your house, because the parents are concentrating on raising their brood. Trying to relocate them is hazardous, both to the animals and to people in many cases, and pointless. Let them be, and in a few weeks the young will be old enough and move out on their own – about the only exception to this is bat colonies (more below.) Once there are no young to raise, the adult animals often leave on their own – nests are primarily for young – but they can also be encouraged to leave or stay out at that point. Squirrels are pretty bad about wanting to return to successful nest areas, and will even chew through wire mesh at times, but most others take the hint and find better places to live.

“But what about rabies?” Animals raising young, even in the eaves of your house, are not an especially high risk. Contrary to belief, rabies does not cause animals to leap suddenly out and attack people; those events are remarkably rare. While anyone should be quite cautious of any mammals that openly approach, living near them does not place anyone at special risk – you’re at greater risk of being killed by the tree near the house falling on you, and we won’t even talk about road risks. Like snake bites, most contacts with rabies vector wildlife occurs by people initiating the contact.

beaverspoor“Animals are doing damage to my property and need to be removed!” No. I can’t tell you how much this attitude annoys me, but that’s what a blog is for, right? Wildlife goes where the habitat is ideal, and pays no attention to humankind’s imaginary idea of “property.” First off, anyone should enjoy the opportunity to see behavior, something that is often hard to accomplish even when making the effort. If someone has wildlife around, chances are they aren’t in a high-rise apartment, which means they wanted to live with at least some vestige of nature visible; surprise surprise, it comes with other animals. While we might decry the damages to our gardens or landscaping, that’s part of the territory, just like road noise and power lines. Learn how to cope, and the ways to exclude animals from certain areas so we can have tomatoes. I’m sorry that a $500 tree was stripped, but no one should have planted something that was that appealing to the local species in the first place, and chances are, numerous appropriate trees had been cut down first so that the fancy landscaping could be put in its place (and I used to work for a landscaper, too.)

Trapping and removal is rarely effective. If there’s a habitat, someone else will move in. And wildlife populations have been shown through numerous studies to be fairly self-regulating; the issues come because habitat destruction by humans is not. We can put in housing developments much faster than the natural cycles of population reduction and management, and those displaced animals end up somewhere. They likely feel the same way about us – dread the point where they develop opposable thumbs.

But what about bats? Ah, the poor little guys! Much of our population considers them ugly and creepy, not at all helped by folklore and horror stories, yet bats are actually way cool mammals, and good to keep the insects down. But most species nest in colonies, and this does sometimes mean in attics, which can produce lots of guano (bat poop) and increases the risks of rabies exposure, primarily when one gets lost and ends up within the human spaces of the house. However, the damage that they can do is minuscule, since they do not dig or gnaw, and excluding them only takes 1/4″ hardware cloth (small-holed wire mesh.) Again, this should be done when no young are being raised, and should always be done with gloves and a breath mask (guano turns into dust easily and can be inhaled.) Should you find a bat in your house, contact your local animal control, since states differ on how they handle potential exposures.

I said I’d get to this: So you want to learn how to rehabilitate wildlife? Once again, this is actually encouraged, but like riding a motorcycle, it should be done properly and responsibly. If there isn’t a wildlife center or organization available in your area, contact your regional Wildlife Resource Commission office (for the US at least) to find out who in your area can train you, and most especially what permissions you need. In the US you’ll need at least one permit, possibly several. What you’ll mostly need is training, because any species requires a decent body of knowledge to tackle well – which also means pick a species, at least to start. Your local rehabbers can suggest a few, which might mean picking something you didn’t initially desire, but which is either easier to learn or presents the greatest needs within an area (and again, is this about you, or the animals?) Expect to spend a lot of time at it, since most animals need lots of attention – mammals may need feedings every four hours around the clock, and birds every 15-30 minutes during daylight (yes, I knew a songbird rehabilitator that kept baby birds in the desk drawers of her office.) And it’s almost certainly all coming out of your own pocket.

SquirrelFeeding
I feel obligated to say this, too: wild animals are not pets, and should not be raised as such. There are lots of reasons. The domesticated animals we have as pets, like cats and dogs and horses, have been bred that way for thousands of years and quite likely were chosen because they already had traits that assisted the process. Animals do not domesticate by simply raising them around people, and in many cases have behaviors that cause them to run afoul of our own (I mention once again the squirrel scar I bear – that story was posted a few years ago.) Many animals also do not have diets that are easy for humans to replicate, meaning that they’re unlikely to thrive and may develop serious disabilities. But most distinctly, what we might imagine them to be like is rarely ever the case – they are highly unlikely to bond with humans in the slightest, and aren’t going to make good companions, do tricks, or even exhibit any appealing personality. They belong in the wild, and that should be your only goal.

Now, if the demands of rehabilitation are too much to contemplate, you can always volunteer with a local organization, and do rehabilitation on a rotation as your schedule permits. This helps prevent burnout and lets you have vacations and family emergencies. This also allows you to get involved without necessarily requiring the permits, because you can operate under the aegis of the organization and its own permits (which is how I worked with raptors, since my apartment would not fit the 15-meter flight cages required.) Still, expect to be dedicated to the job, even when it’s unsavory – cleaning cages and wounds, and even euthanizing injured animals, is a requisite part of it all. Not to mention how many species expect live or fresh food. If you’re thinking of cuddling fluffy bunnies, you’re not ready; rehab requires lots of ugly stuff, and very little bonding – they’re not pets, but wildlife, and need to be wild.

Or, simply donate money or materials. That works too, and is just as necessary – the nice thing about the subject is how nearly everyone can find a niche (provided they accept the reasonable expectations.) Despite such things as Wildlife Resource Commissions and the US Fish & Wildlife Service, there really isn’t money being put into wildlife rehab, especially not from a state or federal level. The vast majority of organizations run solely on donations and grants, and often even have to have veterinary services donated. Experienced workers are great, but donors are just as important, if not more so. Even people who can promote greater donations are important. Just about everything is grass-roots level, all of the time – the few exceptions are great, and demonstrations of what can be done, but not what you can expect throughout the field. Your help, whatever it is, will be appreciated.

A final note: find out, now, how to contact your local wildlife people. Before you find yourself with an injured owl on your hands. In some areas, it’s not self-evident or easy to find, and if it’s not a registered organization, you can forget about searching any telephone listings. Local animal control usually knows, and the 24-hour emergency vets. Often, 911 operators do not, and even local law enforcement may be stumped. A few minutes to get prepared can save a lot of hassle later on, and as I said, we’re entering baby season.

Hope this helps!

Room for one more

I had this in the back of my head for a few days, just as I’ve done for several years prior, when I remember to check that is (which is infrequently.) But the setting moon was going to be just 1.1% illuminated this evening, right after sunset, and the sky was crystal clear, so I elected to try again.

[Wow. That last was five years ago – I wouldn’t have said that much time had passed.]

I was out in a great location for visibility, being able to see within a couple of degrees of the astronomical horizon, which is essentially what you’d see out over the ocean – my visibility wasn’t that good, but close. And when I knew it should be coming into visibility, I fired off a wide frame just to see if it could be spotted later on in editing, because I hadn’t seen any sign of it yet.

And indeed, it could be. See it there? This is shot at 150mm, the widest setting for the Tamron 150-600, and I made sure to include the streetlight for reference. But if you’re not seeing it, there’s this different crop of the same image:

tiny crescent moon making first appearance, long crop
That’s the whole height of the frame, so you should be able to go back and locate it in the original above it, but I admit it’s very very faint. Not long after taking this frame, I found the crescent in the binoculars and the with the long lens, this time at 600mm, and began firing off frames.

tiny crescent moon against twilight sky after sunset
Venus was up already, so I was using that, and passing airliners, to attempt to focus tightly, thought this one is probably just a hair off. But I like the color.

After a few minutes, I decided to try the 2x teleconverter for some frames, though to be honest, the edge that it provided was only to make things bigger in the frame, because it wasn’t likely to resolve things any better and increased the risk of both slower shutter speeds, and greater susceptibility to camera shake, reducing the quality.

And then of course, there’s atmospheric distortion, which I wasn’t likely to get past – North Carolina always has a certain higher background level of humidity, except on very rare occasions, and even when the sky looked totally cloud and haze free, the banding visible near the horizon meant that distortion was going to be a factor – this was as sharp as it was going to get, especially since such crescents are only going to be found right down near the horizon because they’re otherwise overwhelmed by the sunlight and atmospheric scatter of that. Still, the barest hint of the lunar disk is becoming visible at this point, as the earthshine was showing through the darkening sky. It shows better a short while later:

tiny crescent moon and bare hint of lunar disk against twilit sky after sunset
Sunlight is still hitting most of the Earth that faces the moon at this point, and that’s reflecting off of the lunar surface back down to us; it’s actually close to as bright as it can get. But locally, the sky was catching too much sunlight bouncing through from over the horizon, so the earthshine wasn’t becoming visible until those light levels had dropped far enough.

It was getting quite close to setting at this point, already well below what I would have been able to see at any other shooting location that I’ve tried this within.

tiny crescent moon approaching horizon above traffic signals
These are the traffic lights for the low drawbridge that crosses the river that I was shooting across, and I’m amazed that they came out this distinctly, since they were only silhouettes to me standing there. I realized that I really didn’t want the moon setting against traffic signals, so I shifted my position along the river edge a short distance, but had too little time to get picky.

tiny crescent moon setting over trees and traffic on bridge
I had attempted a few longer exposures to try and bring up more earthshine detail, but the wind off of the river and the lowering light levels were conspiring against me and those pics are being discarded. Here, we actually have the drawbridge barriers and passing traffic in the scene. The last images that I took, with the moon disappearing into the trees, were also far too shaky and not what I wanted, so this is the end as far as I’m concerned. But it was worth the effort, and The Girlfriend was along for the ride this time and got to see it through the binoculars as well. Nice little short excursion, and allowed me to squeeze in even more pics and a post for the end of the month.

Now, I actually have a goal to capture the moon illuminated by less than 1%, but .9% is probably going to be the absolute minimum I could accomplish, if that. It would mean the moon is even closer to the sun, and thus more embedded in twilight while being dimmer, so it’s a very fine edge, and the last couple of times that I tried, the humidity was too great. Meanwhile, the conditions are actually sparse, because there are only two days a month that it’s possible: the day before new moon, when it would occur just before sunrise, and the day after where it appears after sunset like this. Yet not every new moon presents these conditions, because orbital mechanics dictates that those narrow periods may be more or less illuminated, and that crucial .9% period occurs elsewhere on the planet. But I’ll keep trying.

A new record!

nineteen turtles sharing the same tiny island to bask
The turtles outdid themselves today, and I wasn’t going to pass up the opportunity to post another photo. There’s nineteen of them on this little tussock, now known to us as “Turtle Island,” because of course. And there’s even room for more if they’re careful (which they often are not.)

Near as I can tell, these are entirely eastern painted turtles (Chrysemys picta picta) and yellow-bellied sliders (Trachemys scripta scripta) – the smoother, smaller, and flatter ones are the painteds.

Don’t believe me (about the count, I mean)? Here’s a version annotated with red dots for the heads:

While I was getting these frames, there were at least four more on the bank of another tussock island, a couple on various small logs, and at least five large ones that could bask in the shallows near the channel to the bayou portion of the pond. And this says nothing about the ones not yet out of hibernation. We gots a lotta toitles, is what I’m saying.

One of these days I’ll get around to posting the video of them jockeying for position, taken a couple weeks back. Not as many as here, but the competition was amusing.

Estate Find IX

This week’s find we credit to The Girlfriend, who discovered this little spud right outside the front door, of all places.

likely eastern mud turtle Kinosternon subrubrum in front yard
This is, most likely, an eastern mud turtle (Kinosternon subrubrum,) but truth be told, there is a fair amount of variability in markings that cross over with the striped mud turtle, especially in North Carolina where the striped mud turtle is not striped. Given that, I’m not worried about someone looking at these pics and pronouncing me utterly wrong.

This is average size for them, and in fact, I don’t think I’ve seen an adult varying from this by even ten percent – I always liken their appearance to hand grenades. I originally considered this a musk turtle (also colloquially known as a ‘stinkpot’) based on the pungent urine that it produced, which still lingers on my hand as I type this, but there’s a detail that rules this out.

While I don’t openly encourage handling of wild species, I don’t condemn it as ‘interfering’ or anything, since it’s trivial (especially compared to the hazards that they face routinely,) and in cases such as many turtle species, it’s the only way you’ll determine identifying characteristics. The musk turtle has only one hinge to its plastron, not allowing the legs to be fully protected, so this shows that it’s not that species at least; the head is to the right, but you can see the secondary hinge that closes off the hind legs. It also partially demonstrates that mud turtles are kind of like a cross between box and snapping turtles – handling should be done circumspectly, but that’s true of any species; don’t do it if you don’t know what you might be in for (or are offended by your hands smelling rank.)

likely eastern mud turtle Kinosternon subrubrum barely peeking from shell
The turtle was remaining reclusive, and even when put down, it extended its snout only far enough to see that I was still there. I popped the flash to fill in those shadows a little, but the eye is still not really visible.

So I let it be, while pulling up a lawn chair a short ways off and waiting…

likely eastern mud turtle Kinosternon subrubrum outwaiting the photographer
… for quite some time – over a half-hour, and this is as far as the turtle peeked out, determining that I still lurked nearby. I amused myself with other pics that I could get from my seat, some of which you may have already seen (I work on these posts in odd order sometimes,) which likely didn’t help because I was aiming the long lens in multiple directions and was obviously not just some lawn decoration, so the turtle stayed put. I eventually went indoors to do some other things, but came back out about 20 minutes later to find the turtle gone, though it didn’t take a lot of searching to find it again.

likely eastern mud turtle Kinosternon subrubrum heading out across the yard
It was heading purposefully across the yard, out in the open, but stopping to nose down into the ground litter from time to time, eventually emerging again and moving on to another spot to repeat the performance. I’ve since learned that mud turtles are largely but not entirely aquatic, hibernating on land a very short ways underground, in spots with lots of leaf litter but often with at least a hint of sunlight, so they can feel when the days get warmer. That would appear to be what this one was doing – it was quite a nice day, but it’s not expected to remain that way and the turtle might have been looking for a new hibernation spot, though why it was out now, I can’t say. Curiously, you can see some dried algae adhering to the shell, which if my sources are correct, may have been there since before it entered hibernation last fall.

likely eastern mud turtle Kinosternon subrubrum re-emerging from testing burrows
The yellow-bellied sliders and eastern painted turtles in the pond are active as soon as it gets marginally warm, and will be out basking on sunny days, but the mud turtles would seem to have a more seasonal schedule and possibly shouldn’t have been active yet. So is this an anomaly, or is the schedule not that specific? Don’t know, but it’s this week’s find regardless. And now I have to go wash my hands again
