arctic fox Vulpes lagopus in summer coloration, from the NC Zoological Park in Asheboro NC
I’m guessing that more than a few people would fail to recognize my photo subject here, because virtually no source ever shows them at this time of year. This image is actually the first in the ‘Mammals’ category of my slide archives – not the first mammal that I’ve shot (that title probably predates this one,) but the first I took when I switched over to slides. It dates from August 1998, and was taken at the NC Zoological Park in Asheboro. This is what an arctic fox (Vulpes lagopus) looks like in its summer coloration.

For a long time, this was the only way that I’d seen them, given that I live hundreds of kilometers from the Arctic Circle and didn’t tend to visit the zoo in the winter. This coat blends in quite well with the summer conditions up there though, where some days it might even get warmish – actually I don’t really know what temperatures it reaches in the summer, though I’m comfortable saying that I wouldn’t wear sandals as frequently as I do here.

But when I say, “arctic fox,” most people (me included) picture this:

Same place, and potentially even the same fox, only eight years (and a few months) later in 2006, christmas eve in fact. The weather that day was remarkably warm – even sandals were feasible – but the fox had developed its winter coat by then and now looked properly arcticky. And of course, garnered a lot more attention now by being pure white and fluffy. Which isn’t the goal in its native conditions, but then again, there are very few human females in such locations, and a lot more golden eagles and polar bears that couldn’t give a fig about ‘fluffy’ but have a harder time spotting a white potential meal against a white snowpack background. As do the foxes’ prey, consisting largely of voles, seal pups, and lemmings.

Some things I don’t have as specific goals but am happy to obtain anyway, and variations in coloration or plumage are good things to have in stock. For any given species this might be challenging – breeding plumage especially, since it often lasts only a few weeks and may be sported by just one sex, so capturing good examples of this might take a lot of time. Granted, that wasn’t the case here, and I wasn’t trying to accomplish this anyway, but it was a productive trip overall.

Last week’s birds

It seems only fitting (perhaps that’s not the right word) that we start off with something that is not birds.

sapling against sunrise showing numerous spiders
Shooting sunrise on Jordan Lake last week, I did a quick silhouette with one of the tiny, unidentified trees/bushes that appear sporadically out into the water a short ways (actually, this may be a buttonbush, Cephalanthus occidentalis.) Not the most prepossessing of plants, given the terrible shape of the leaves, but I was after the prominent long-jawed orbweaver spider, and only afterwards realized that I’d caught more than one – in fact, I’ve made out at least seven different spiders, or parts thereof (like legs peeking out) in this single frame, though granted, some of them require full resolution to discern.

But okay, on to the topic of the day.

osprey against sunrise on Jordan Lake
As the sun was just making its appearance over the trees, a lone osprey (Pandion haliaetus) cut across the sky, probably not able to see the sun fully from its altitude, but at least catching direct sunlight. The yellow color of the sky and the faint wisps of clouds indicate that it was a boring sunrise, but it’s central NC, so what else is new?

The great egrets (Ardea alba) were at least appearing here and there, not terribly active, but occasionally allowing some closer shots. One flew into a tree nearby, a little surprising, and sat up there preening even though we were obviously very close by.

I liked this particular pose, aside from the sharp focus, because the egret’s head was held at just the right angle to cause its own cornea to light up the eye so distinctly while that portion of the head was shadowed. But only moments later, it fixed us with a faintly suspicious look before returning to its preening.

Definitely get the impression that the egret slept wrong last night, and also that we met with its disapproval somehow – probably has a thing about groundlings.

At another section of the lake, about a kilometer off, the vultures were congregating not just in great numbers, but without much regard for our presence either.

This turkey vulture (Cathartes aura) was at the edge of the parking lot at the boat ramps and had spread its wings for the morning sun as we crept closer, then peered at us straight over its back. Moments later, it decided that it was being too obvious and folded the wings with a bit more modesty.

A short distance away, a large number of black vultures (Coragyps atratus) were hanging out, mostly down near ground level, which allowed some great portrait opportunities, if you’re inclined towards that kind of thing.

To the best of my knowledge, I wasn’t looking especially on the verge of dying (at least not any more than normal,) and I saw no indications of other food sources nearby, but they definitely were clustered around as if waiting for a handout. I made a joke about not having any dead crumbs, which passed completely without notice – I’m unappreciated in my time. Likely long afterward, too, but it sounds better this way.

I definitely don’t see enough of the red-headed woodpeckers (Melanerpes erythrocephalus,) and a trio, at least, provided some bare opportunities as they flitted among several trunks surrounding us. They allow me to provide a small illustration, anyway.

There were a pair working up this dead trunk, but they didn’t want to show themselves at the same time. However, since I was shooting against the brighter sky, with nothing else in the frame (and this is cropped tighter, so you can imagine that the non-sky portion wasn’t very significant,) I had dialed in some exposure compensation, 2/3 stop overexposed, or at least, over what the camera logic considered ‘proper,’ which is a middle tone, what’s called, “18% grey.” Without it, the photo would likely have been a bit dark, more than ideal, though it could be argued that this is a tad bright. Now we face in the opposite direction.

This is with the same compensation, now almost directly towards the sun (it was pretty high at this point, but in that general direction.) Even with the compensation, the frame is far too close to a silhouette, though admittedly, there were two other trunks in the frame (cropped out here) skewing the exposure reading slightly. What it shows is that getting a decent exposure while aiming into the sky can be tricky, and it’s a good idea to bracket the exposure whenever possible – a lot harder to do with hyperactive subjects that hold a decent pose for a mere second, but that’s how it goes in nature photography. Luck plays a large part, and exploiting that luck plays another.

Speaking of that…

osprey Pandion haliaetus landing on overhead branch with small fish
Spotting this osprey as it cruised in to a landing spot allowed some nice detail as it touched down in a tree almost directly overhead, a great opportunity, but I knew we were too close for comfort and it would be unlikely that the osprey would consume its meal there. We fired off the frames while we could.

Not exactly a huge meal here, and we saw no views of any osprey in the area actively hunting. I wanted the eyes of both the osprey and the fish in the frame, though with the bird bobbing around on its perch, this wasn’t something to actively time – just fire off the frames and see what you got afterward. And then…

osprey Pandion haliaetus looking directly at photographer as autofocus tracks to intervening branch
… that sonofabitch autofocus picks the exact moments when the osprey looked directly down at me to track in to the branch instead! Listen, I think autofocus is a marvelous application of technology, and it’s improved every year, but it still has far too many imperfections and quirks, which is why I frequently switch it off. I really want it on a thumb button, though, and not on a switch (one among four) on the body of the lens, especially since it sits right next to the vibration control switch and feels exactly alike.

A portion of this is my fault, though, since I programmed the camera to bias autofocus to track closer when it lost its lock. Here’s how it works: handholding a heavy lens with high magnification is tricky enough, and it takes the slightest twitch to have the subject leave the autofocus area of the frame – this is made even worse with moving subjects, or subjects high overhead where the position of holding the camera (and your own head) becomes awkward. I set the the AF to tend towards moving in slightly when it lost focus, for three reasons. The first is that it’s far too easy for the camera to then try to grab the horizon, much farther than the subject all too often, and by the time it tracks back the subject has been rendered so far out of focus that regaining it, sometimes even seeing it, becomes difficult and time-consuming. This was occurring too much as I tracked a bird in a dive and it crossed the horizon line, whereupon I’d miss the crucial entry into the water. Additionally, it more cases than not, the bird was actually coming closer, so tracking inward helped these circumstances. And finally, tracking inward (especially with the focus limiter on, which prevented the focus from traveling closer than 10 meters,) would more often not go as far out of focus as going to the horizon, so the camera would regain focus faster. All this does increase the chance that it’ll grab an intervening branch, however. I’d like to be mellow enough to say, “So it goes,” but more often, the response is, “goddamnitall anyway.”

Suffice to say, the osprey flew off immediately following this, so the 4-6 seconds of photo opportunities ended there. I could easily have missed all of the shots, or even seeing the osprey at all, so I’m well ahead of the game with a few nice frames. But still…

Storytime 36

new kitten looking vaguely suspicious
This week’s entry is perhaps only part one of an ongoing story – nobody’s really sure yet. We’ve been playing it by ear.

It started almost two weeks ago when I went into work in the evening to block off some days for students and such. There was a handwritten note on one of our delivery vehicles informing us that there was a kitten up on the spare tire underneath the car, so I got my flashlight and checked it out carefully, seeing nothing. I thought the note might have been hours old or better, since the car wasn’t used at all that day, and didn’t think a lot of it other than vowing to keep my eyes open. But as I was leaving myself, I spotted the kitten underneath the same car and the saga began.

I’ve had a lot of experience with feral and semi-feral cats, meaning those that have acclimated, fully or in part, to living in the wild despite being a domestic species; two of my cats, for years, had in fact started out as feral kittens that never fully tamed down to truly domesticated – one of which would still hiss at me at times when I entered the room without warning. I spent years reassuring her, kindly and gently, that everything was okay, each time it happened, and receiving less-than-acceptance in return – usually she just cried forlornly at me as if I had threatened her. Then one day, intent on doing something and entering the room to this antisocial greeting, I merely said exasperatedly, “Oh, give it up, I haven’t killed you yet” – and she immediately calmed down. I’d discovered, by accident, that my placating behavior was stressing her out more than my normal bluntness.

Anyway, back to the kitten. I immediately called The Girlfriend and asked her to bring cat food and a carrier (we live far too close to where I work,) and while waiting for her to appear, I watched the kitten with some coworkers, talking softly to her from a distance and getting the very-reassuring sign of a raised tail; she wasn’t fully feral and recognized people, even as she distrusted us. When The Girlfriend arrived, we set up some food near the car, with the open carrier nearby, and sat back to watch what happened. In short order really, we’d coaxed her pretty close with food, got her used to our presence, and then trapped her in the carrier with far less effort than I’d ever expected (I was actually trying to dig up some kind of string or wire from my car to pull the carrier door shut once the kitten had ventured within, when The Girlfriend simply crept up from the blind side of it and gently pushed the door closed.)

Back home, we let her out onto the screened porch, separate from the other cats, provided food, water, and a litter pan, and let her settle in for the night. Since I wasn’t working the next day, I could venture out to try and socialize her, and within a couple of days she had become completely trusting and more than a little enamored of people – again, perhaps.

new kitten being mellow
She’s only about eight weeks old, without a full set of teeth yet though fully weaned, and while not exactly hyperactive, it’s safe to say she has the short-attention-span thing going on; she’s started to fall asleep in my lap at least six times, only to suddenly startle herself awake, at no provocation whatsoever, and find something else to do (she’s managed to drift off once, though.) She adores her various toys, and does like having restrained wrestling matches with me.

I call this one, “I’m crushing your skull,” but I don’t know how few people will get that reference…

The big question remains now: Are we keeping her? And this mostly revolves around whether the other cats will accept her or not. Coincidentally, it was Labor Day weekend eight years ago that started that whole story and eventually brought them into the house, but their age and the fact that this is another female throws the whole thing into question. We’re not sure how well, if at all, they’ll accept a newcomer.

I predicted that Little Girl would be easier to convince than Kaylee, but so far, Little Girl has been a lot more reserved and reluctant…

… while Kaylee has been showing far more interest than I had given her credit for:

It probably helps that they have complementary coloration. But it also helps that the kitten is remarkably imperturbable, treating warning hisses as momentary setbacks and not at all shy about greeting the others.

A small note here: If you’re faced with introducing a new cat to established ones, it works a whole lot better to let the new one have a room of its own for a few days, and introduce the established cats into that. To them, this puts them into the new cat’s territory, which dulls their protectiveness and makes then feel slightly out-of-place so they’re less aggressive/defensive. There might still be confrontation, but much less than if you simply drop a new cat into their home.

I am reminded of a circumstance, many years back in my late teens, when we had a young cat that had been retrieved from the middle of traffic and had become established in our house for several weeks; the other cats simply avoided him, so he learned to play on his own. Then we found another, a female, slightly younger and thus a good playmate age, but he wanted absolutely nothing to do with her, even as she was desperate to make friends. The slightly older cat adored wrestling through a quilt that was draped over the upstairs banister rail, fighting mock-fiercely with the amorphous thing (usually my hand) behind the thick fabric, and she discovered this on her own, by accident. They would have fantastic wrestling sessions until one of them would inadvertently peek around the edge and provoke the older male to hissing in defense. This lasted all of three days until he got over it, whereupon they trashed the house each night in their enthusiastic free-for-alls.

Anyway, we’ll see how it goes from here.

Quick! Go here before midnight!

If you were paying close attention, you might have noticed that I have a tendency to post religion-bashing stuff on Sundays, because I’m perverse – we atheists are mean that way. I wasn’t really planning anything of the sort, and have been working on site updates today, but Professor Ceiling Cat has a fun post over at Why Evolution Is True, and you should check it out. Quick, while it’s still Sunday! I might even appear in the comments myself, eventually, to address a couple of points that I haven’t seen anyone else tackle yet.

Basic explanation: after a guest post by Ben Goren elaborating on the problems with theodicy, a commenter by the nym of “Nixak” provided a lengthy response enumerated in six major points. For a brief observation just to include something more than a link, this is yet another example of someone’s personal interpretation being forwarded as if it was orthodoxy. One of the points, believe it or not, is that god does not respond to prayers unless his proper name is used, which apparently not enough people know. I admit, this is the first I’ve heard any argument of this nature outside of comic books – what if you say it backwards? How about three times? I have so many questions…

Anyway, for now, see how well the commenters are handling the points therein. I’ll be back shortly.

The neighbors

Living on the edge of the woods is a good thing. For some reason, a small herd of White-tailed Deer (Odocoileus virginianus) has taken to visiting roughly around 2:30 PM some days, and when the temperature is cool enough that I can leave the window open, I can hear them foraging. This one was a little surprised to see someone appear in the doorway so close by, but I wasn’t moving enough to spook her off, and she provided several nice portrait poses.

Deer are foragers, rather than grazers, which means they don’t eat grasses like cows or sheep. Instead, they seek new saplings, leaves, vines, shoots, and berries – and on occasion, garden plants and The Girlfriend’s tomatoes and peppers. In this area, they make things a little more convenient for forest wanderers like myself, because they’ll keep “greenbrier” (the colloquial name, I’m not sure of the exact species) at bay, a tough wandering vine that sports large thorns. Greenbrier can quickly turn shaded woods into impenetrable thickets, and makes walking among the trees a chore at times, but deer like it and their regular visits will keep the vine from gaining a firm hold.

Yesterday afternoon, I added some water to the thirsty potted salvia I have sitting on my railing, and as the water pooled on the soil surface before soaking in, a tiny face appeared among the leaves, startled by the sudden flood. This began a tortuous session of macro photography, as the juvenile Common Grey Treefrog (Hyla versicolor) did not want to hold still for the giant lens looming in its face, and kept hiding under the leaves. Right now, as I type this, it has ventured out of the pot and is working its way along the railing. This has me a little curious, since both of these species are primarily nocturnal and the days have been unseasonably hot, all the more reason to hole up during the days. 6:30 PM is a little early to see treefrogs getting active – night won’t fall for about another two hours.

Treefrogs have distinctive toes, ending in a broad and moist pad that lets them cling to vertical surfaces effortlessly. In fact, it can be a little startling to see them jump against a wall and remain there instead of bouncing off. This trait lets them forage for food high in the tree canopies without needing claws, and also lets them scale rocks, leaves, and yes, even people that attempt to grab them. You can get an idea of the size of this specimen by my ugly thumb, included in this shot for scale. I normally see them much larger than this.

It’s a little late in the season for mating calls, so I’m not expecting to hear anything from my neighbor when it gets dark, but we’ll see what happens. I’ll probably leave a light on near the potted plant and railing, to attract the flying insects that serve as frog food. I might as well make it feel at home, since it provided enough photos for me – hey, I’m a dude ;-)
