Logbook: Porcupines

Moving to Maine has meant, among many other things, crossing into the range of the North American porcupine. We didn't see much of them for the first year, except in the form of roadkill, but this winter they've been very evident. I spotted the adult above high up in a pine tree in a little wood, and at first mistook it for an owl (which we also have here). With some difficulty I managed to get underneath it and take some photos; the animal undoubtedly knew I was there but showed no reaction.

The juvenile below showed up on the side of a mostly unused dirt road one day and lingered in the same spot for the three or four succeeding days. Porcupines may be slow to sense the presence of another creature, even one walking a dog on a leash, but eventually this one would move off. There may be sillier sights on earth than a juvenile porcupine waddling across a dirt road, but there can't be many.

In another location, probably far enough away to represent a different territory, I've been keeping an eye on an active den in a dead tree, which judging from the depth of the pile of porcupine droppings around it has probably been in use for some time. Porcupines will den up together, so it's hard to say how many occupants this one may have, but by getting a bit closer I can see that there's definitely at least one.

The Wisdom of the Burrowers

Anthony J. Martin, from the author's website:
Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters: fires, droughts, storms, meteorites, global warmings―and coolings. On a grander scale, the first animal burrows transformed the chemistry of the planet itself many millions of years earlier, altering whole ecosystems. Many animal lineages alive now―including our own―only survived a cataclysmic meteorite strike 65 million years ago because they went underground.

Pioneers

The development where we live now is a relatively new one, and there are patches of recently disturbed "vacant" ground dotted around its periphery. In particular, there's a knoll out our back window that was scraped and reshaped by earth-moving machinery just last year. In one growing season it has gone from bare earth to a thriving and complex meadow ecosystem. A cover crop may have been broadcast for erosion control, but most of what has sprouted up appears to have arisen from seeds that lay dormant in the ground for months or years, awaiting an opportunity to germinate.

My unscientific survey finds, just beyond our walls, Queen Anne's lace, yarrow, great mullein, hare's-foot clover and several other clovers, crown vetch, purple vetch, and bird's-foot trefoil, various grasses, fireweed (Erechtites hieraciifolius), asters and goldenrods (probably several species of both), boneset (which a worried neighbor mistook for poison hemlock), thistles, and evening-primrose. Down an adjoining embankment, where there has been growth for a longer period, there are cattails and phragmites, blackberry brambles, pokeweed, whorled and purple loosestrife, and agalinis. That's not counting the ones I haven't noticed or can't identify. A healthy percentage of these plants are so-called "aliens" that weren't part of the precolumbian landscape of North America but have long since become naturalized.
An even less scientific survey turns up a host of insects, notably various dragonflies, bees, wasps, beetles, and a scattering of butterflies (but few swallowtails and monarchs, perhaps because the milkweeds haven't yet appeared). There are orb-weavers and other spiders, and unfortunately ticks as well. We've had regular visits from wild turkeys and deer and occasional sightings of coyotes, groundhogs, and skunks. One evening we spotted a porcupine browsing unhurriedly and almost invisibly among the clumps of herbage.
Earlier in the summer there were woodcocks buzzing and courting at dusk, and goldfinches, bluebirds, hummingirds, and mourning doves have been abundant. We hear owls often, and no doubt they hunt for voles and other small mammals as soon as the sun goes down.There is certainly far more that we don't see than what we do.

A dirt road leading out of the back of the development has been widened and graded in the last few weeks, and further construction is expected. No doubt the resident and transient flora and fauna will be in flux for some time. But it's astonishing how quickly and vigorously life can seize hold, given half a chance.

****
Many of the plant species mentioned above, as well as their faunal associates, are profiled by John Eastman in The Book of Field and Roadside: Open-Country Weeds, Trees and Wildflowers of Eastern North America (2003). Like its companions The Book of Forest and Thicket and The Book of Swamp and Bog it is illustrated with line drawings by Amelia Hansen, and was published by Stackpole Books; all three volumes now seem to be out of print.

Prickly issues

The poet Donald Hall was born and raised in suburban Connecticut, but he spent many of his summers at his maternal grandparents' farm in New Hampshire in the 1930s and '40s, an experience he recollected in a memoir entitled String Too Short to Be Saved. Though he was capturing a disappearing way of life, and remembering it fondly, he largely avoided the lure of nostalgia. There are golden afternoons spent haying and tending chickens in the book, but there is also alcoholism, mental illness, and suicide among the neighbors. He would later own up to embellishing a bit; in a reprint he confessed that the abandoned railroad on Ragged Mountain that he described didn't actually exist. It was another passage in the book, though, that initially perplexed me. Hall describes a day on the farm in the company of his grandfather:
We walked slowly uphill to the barn, which looked like a rocky ledge of Ragged in the gray light. When we were nearly to the milk shed, he suddenly pointed upward at the branches of the great maple next to the old outhouse. "Look!" he said. "There's a hedgehog!" I followed the angle of his finger and saw what resembled a bird's nest at a fork in the branches, indistinct in the late light. "Let's see how you are with a shotgun these days," he said.
The animal is dispatched, not by Hall, who misses four times, but by his grandfather. In a later chapter, when the grandfather is dead, Hall returns to the farm, spots three more "hedgehogs" in the trees, and brings them down.

As any naturalist can tell you, there are no wild hedgehogs in New England or anywhere in the Americas, nor do they readily climb trees (pace Maurice Sendak), nor are they considered agricultural pests (though they were once popularly thought to suckle milk from cows). There are, of course, porcupines, but no one who had grown up in New England (and was later educated in part in the UK, where there are hedgehogs), would be likely to confuse the two. So what gives?

As it turns out, Hall was simply following vernacular tradition. Although "porcupine" (unlike "opossum" and "skunk") is a European word dating to the Middle Ages, few English colonists to New England would have ever seen an Old World porcupine, as the closest ones live in Italy, and faced with a spiny creature they simply borrowed the familiar name "hedgehog." The usage was common enough to have been written into law; as late as the early twentieth century the state of New Hampshire was paying bounties for killing "hedgehogs." The bounty was repealed in 1979, by which time the word had been corrected to "porcupines."

Another word for hedgehog is "urchin," from Latin ericius (see Spanish erizo, French hérisson). Today that word refers to a street waif, but its original meaning is preserved in the name for the spiny echinoderms known as "sea urchins."

Welcoming committee

We're in the process of completing our second relocation of the year, having most recently moved from temporary digs in Portsmouth NH to our new permanent address just over the Maine border. On one of our last mornings in New Hampshire I went for a morning hike and saw this bobcat crossing the trail just ahead of me. I quickened my pace a bit, figuring the cat would likely disappear into the brush before I could set up a shot, but it seemed to be in no great hurry and even turned around to look back at me for a moment. I've seen bobcats a few times before, but this is the first time I've had one pose. After a few seconds it moved off.

The mid-fall Maine weather has been far warmer than advertised, with temps grazing 80, and for several days the side of our house swarmed with ladybird beetles and assasssin bugs. The latter weren't living up to their name, perhaps because they know that the beetles are somewhat toxic; the two species crawled around each other, pursuing their separate interests.

Then last night, around 8:30, an owl started hooting outside and kept it up for roughly a half-hour. The noise kept setting off our dog, and finally I took him out for a look. The bird, probably a great horned owl, was clearly visible in the top of a tree just across the street and was undisturbed by our presence. It flew off eventually but made a brief return just after dawn.

Turtle Diary

Two days, two eastern box turtles. This mostly terrestrial chelonian, considered a "species of special concern," is widespread in our area but probably not all that common numerically. I see maybe one a year, often in more or less the same spots. The empty shell above may be the remains of one I saw on two occasions a few years ago. It appears to have succumbed to a predator strong enough to pierce its armor. No such grim fate as yet for the red-eyed male below, which I observed when he was, improbably, in the process of climbing over a stone wall. I kept my distance and he held his ground.

Red in Tooth and Claw

Our dog came upon this large Chinese praying mantis in our yard this morning in incriminating circumstances. The mantis was on the ground directly beneath our hummingbird feeder, and I found the insect surrounded by small feathers, with some of which it appears to have bedecked itself according to the custom of hunters from time immemorial. It reared up in an intimidating manner and the dog, who is no fool, backed off and quickly lost interest.

Until I can decide its fate I have brought it inside and put it in a transparent plastic container where I can keep an eye on it, and vice versa. I can't simply release it; it's an invasive species and they do eat hummingbirds, as improbable as that seems. On the other hand I can't quite bring myself to kill it.

For the last few hours it has been hanging on upside down to the lid of the container, which permits the passage of air. I gave it three Mexican bean beetles in case it got hungry, but they appear to have died of fright. Now it's staring in my direction, awaiting my next move. If I am murdered in my sleep tonight you will know who to blame.

Blues


The great blue herons at the local pond I frequent tend to be skittish, flying off as soon as they see me coming down the path, but for whatever reason this one felt like showing off. I walked up to the shore as quietly as I could and finally settled down on a rock just across from the dead branch where it was perching. It gave me a casual glance or two but then settled back into its routine of alternatingly preening and peering into the water. It seemed to be trying out poses and hairstyles, and I have to admit that its full feathered regalia was impressive.
There was a second heron on the other side of the pond that was a bit more standoffish. It also seemed to be a bit smaller and more submissive. Eventually it settled on a branch of its own, but the first heron quickly joined it and chased it off. Maybe it was jealous of those flashy white chest feathers.

The Character of the Cassowary


I wish I were a cassowary
Out on the plains of Timbuctoo.
I'd kill and eat a missionary--
Head, arms, legs, and hymn-book too.
The above lines have been kicking around since at least the 1850s, and nobody seems to know who wrote them. They're geographically inaccurate — cassowaries live in Australia, New Guinea, and thereabouts, not Africa — but they do contain a grain of truth, for this flightless bird is, at least according to most accounts, a singularly surly and aggressive customer, and though it eats neither missionaries nor heathens it does have lethal claws that have led to well-documented, if infrequent, fatalities in human beings who were foolhardy enough not to give the cassowary its space.

Julio Cortázar, who expressed memorable interspecies kinship with the axolotl, had no such empathy with the fearsome cassowary. He describes it in Cronopios & Famas as "unlikable in the extreme and repulsive." In Paul Blackburn's translation, these are its curious properties:
He lives in Australia, the cassowary; he is cowardly and fearsome at the same time; the guards enter his cage equipped with high leather boots and a flame thrower. When the cassowary stops his terrified running around the pan of bran they’ve put out for him and comes leaping at the keeper with great camel strides, there is no other recourse than to use the flame thrower. Then you see this: the river of fire envelops him and the cassowary, all his plumage ablaze, advances his last few steps bursting forth in an abominable screech. But his horn does not burn: the dry, scaly material which is his pride and his disdain goes into a cold melding, it catches fire with a prodigious blue, moving to a scarlet which resembles an excoriated fist, and finally congeals into the most transparent green, into an emerald, stone of shadow and of hope. The cassowary defoliates, a swift cloud of ash, and the keeper runs over greedily to possess the recently made gem. The zoo director always avails himself of this moment to institute proceedings against the keeper for the mistreatment of animals, and to dismiss him.
As entertaining as that fantasy is, reality is hardly less so, and the cassowary's true nature seems to be open to debate. During the travels he described in Gatherings of a Naturalist in Australasia, the naturalist and explorer George Bennett kept several specimens of what he called the mooruk in captivity, and even successfully shipped a pair to England. He found them generally congenial as housemates, although they were perhaps a bit too tame. They certainly weren't fussy about what they ate:
It is well to warn persons, inclined to keep these birds as pets, of their insatiable propensities. When about the house, they displayed extraordinary delight in a variety of diet ; for, as I have previously related, one day they satisfied their appetites with bones, whetstones, corks, nails, and raw potatoes, most of which passed perfectly undigested ; one dived into thick starch and devoured a muslin cuff, whilst the other evinced a great partiality for nails and pebbles; then they stole the Jabiru’s meat from the water. If eggs and butter were left upon the kitchen-table, they were soon devoured by these marauders ; and when the servants were at their dinner in the kitchen, they had to be very watchful ; for the long necks of the birds appeared between their arms, devouring everything off the plates ; or if the dinner-table was left for a moment, they would mount upon it and clear all before them. At other times they stood at the table, waiting for food to be given to them, although they did not hesitate to remove anything that was within their reach. I have often seen them stand at the window of our dining- room, with keen eye, watching for any morsel of food that might be thrown to them. The day previous to the departure of the pair for England, in February 1859, the male bird walked into the dining-room, and remained by my side during the dessert. I regaled him with pine-apple and other fruits, and he behaved very decorously and with great forbearance.
All in all, the presence of the birds seemed to be just one more challenge among many for the domestic staff:
One or both of them would walk into the kitchen ; while one was dodging under the tables and chairs, the other would leap upon the table, keeping the cook in a state of excitement; or they would be heard chirping in the hall, or walk into the library in search of food or information [sic], or walk up stairs, and then be quickly seen descending again, making their peculiar chirping, whistling noise ; not a door could be left open, but in they walked, familiar with all.
Perhaps the mooruk has a gentler disposition than its larger cousins. The smallest cassowary species, it is now often known as Bennett's cassowary in honor of its scientific discoverer.

Abundance



As this anxious summer wears on I've been making regular visits to a little pond not far away, one that, in spite of its diminutive size, hosts an astonishing array of wildlife, all of it unconcerned with our troubles. In addition to hundreds if not thousands of frogs of various sizes, which dash into the water with cries of alarm as I circle the shore, there are snapping and painted turtles, at least one water snake, small fish, and several species of dragonfly. As I arrive great blue herons fly up, issuing unearthly raucous cries, and rabbits, deer, and wild turkey browse the adjacent meadows.


The rabbits have apparently become accustomed to human presence and continue nibbling until I'm almost on top of them, a complacency that may be ill-advised as there are foxes, coyotes, and other predators in the vicinity. The dragonflies don't seem to care much about me either; they dart about, carefully avoiding hungry mouths lurking below the surface of the pond, and rest here and there on rocks and vegetation, only flitting away when I come within an arm's length. The green one immediately below is (I'm told) a female eastern pondhawk, which is a wonderful and appropriate name, for this is very much a hunting creature.


The frogs must be the keystone species here, their sheer numbers guaranteeing their own perpetuation as well as the survival of those who prey upon them. Over the past weeks the young ones have been slowly metamorphosizing from tadpoles. Some are still confined to the water, while others now hop about, soon to lose the remnants of their tails. They're utterly absurd creatures, and as such instantly recognizable as our kin.

Brief encounter



If you haunt the woods on a regular basis you get to recognize the sounds animals make when they're disturbed by your presence. No need to turn your head at the light bounce on dead leaves: that's a grey squirrel. Deer, naturally, make a heavier sound, chipmunks a lighter one, generally punctuated by an alarmed "cheep," and predators, designed for stealth, may be all but silent. But when I heard the animal shown above darting along a stone wall, I knew instantly that I was in the presence of something else. I turned and saw a brown form, squirrel-size but unmistakably not a squirrel. In a flash it disappeared and I didn't expect to see it again, but I clicked on my camera just in case, zoomed onto the last place it had been visible, and after a few seconds it popped out and looked in my direction, curious to see what I was about.

Weasels get a bad press; we speak of "weasel words" and "weaseling out" and none of these terms is intended as a compliment. But I think they're admirable creatures, even if I wouldn't want to be one of their prey animals (they are quite fierce). They aren't uncommon but they're rarely spotted alive; I've only ever seen one other in the wild, and that was decades ago. There's some question about which species this one is, but it's evidently either what the Brits call a stoat (and we might call a short-tailed weasel or ermine) or a long-tailed weasel.

Coincidentally or not, I spotted this one just a day or so after watching an enjoyable BBC documentary entitled Weasels: Feisty and Fearless, which may be available in some regions for online viewing. If not, here are a few seconds of video of my own, all I could take before the creature vanished from sight.

Something else


John Hay:
I think one of the greatest challenges is to watch each bounded living thing with care for its particularity, as far as we can go, to find out we can go no farther. Flower, fish or leaf, child or man — they take none of our suggestions as to rules. Each has a strong language that we never quite learn. No matter how many times I try to describe the alewife by the uses of human speech, or classify its habits, its intrinsic perfection resists me. It is something else. It goes on defying my own inquiring sense of mystery.

The Run
John Hay seems to have been one of those admirable obsessives (think J. A. Baker of The Peregrine) whose fascination with one species (the alewife is a kind of herring) led him to something approaching total psychic identification with his subject. Human beings and their works appear only sporadically in his account of the alewives' annual ascent into the creeks and ponds of Cape Cod — although our dams, overfishing, and pollution in fact constitute serious threats to the species. Other predators — herons and the like — pop up a little more often, but it's the the fish themselves, as they migrate inland to spawn and then, obeying currents and rhythms largely measureless to man, return to the sea, that draw the bulk of Hay's attention. But here and there, in passages such as the one above, one senses, as well, that the book isn't entirely about alewives at all, and that his skepticism extends to, and perhaps arises out of, something rather more fundamental.

Notebook: December Blue



Sunday afternoon. Close enough to shake a stick at to fifty years ago, in my lonely and melancholy youth, Joni Mitchell's Blue was the one record I could never listen to enough. Shut in behind dormroom doors, I played it over and over on a clunky portable hi-fi that was already a museum piece by the time I got hold of it. There was nothing unique in this; Blue was a very popular record, at least among the people I hung out with. Mitchell sang beautifully, in spite of whatever minor technical imperfections she might have had at that point in her development, she was beautiful to look at, but most important, nothing she did before or after, not even gems like Hejira (maybe her "masterpiece," overall), and certainly nothing anyone else was doing to that point, seemed to have the same emotional directness. Sparely produced, with just Mitchell's piano, dulcimer, and guitar and a scattering of contributions from other musicians, Blue seemed to suggest that art — whatever art it was you practiced — could, if wielded with honesty and passion, not to mention genius and dedication, cut through all the pretense and posturing and give a glimpse of how we might talk — or sing — to each other if just once we could drop the masks we all carry around with us, both the ones we show to others and the ones we show to the mirror. All an illusion, perhaps, but that's not how it felt at the time.

Anyway, today I got in the car and drove a few miles to a place I like to go hiking, and I brought along a newly-purchased copy of Blue on CD for the ride. I still have my original LP, but I don't really have a functioning turntable and I'm not a big fan of streaming, so this was actually the first time I'd heard the whole thing in many years. (How did I go so long without being able to listen to "A Case of You"? It's hard to figure.) And I have to say it sounded great, probably better than ever since, whatever the merits of the CD vs. vinyl argument, my car's music system is undoubtedly better than my old hi-fi was. And the emotional impact? Yes, it's still there.
Just before our love got lost you said
"I am as constant as a northern star"
And I said "Constantly in the darkness
Where's that at?
If you want me I'll be in the bar"

On the back of a cartoon coaster
In the blue TV screen light
I drew a map of Canada
— Oh, Canada —
With your face sketched on it twice
But enough of that. It was a seasonably cold but not uncomfortable December afternoon, the skies were partly cloudy, and I hiked for a couple of miles to an overlook I like to visit in the winter when the leaves don't obstruct the views of the nearby reservoir and the surrounding hills. As I neared the top I sensed movement in the sky ahead of me, and looking up I saw an enormous hawk — a red-tail, I think — settle at the top of a bare tree not far off. I switched on my camera but the angle and the light were bad, and before long the hawk leaned forward, leapt off the branch it was perched on, awkwardly bumped another nearby branch, and took flight, quickly disappearing in to the woods behind my shoulder. I finished climbing and sat on the bench that marks the summit for a while, then as I got up to leave I saw the hawk again, in flight above me, and with it a second hawk, probably its mate. The hawks wheeled above me, each in its own tight circle, in effortless command of their element, then gradually drifted further off and out of sight.

On the way home, having traveled several miles by now, I took a back road, and when I neared a small family cemetery adjacent to a horse farm I slowed, thinking it might be a good time and place to see something. Sure enough, as I pulled up, I saw another pair of hawks perched in a tree directly above the cemetery. I switched the camera on even before I opened the car door, but once again the angle was bad and the hawks were too wary. First one then the other took flight, making the same tight circles as the earlier pair, regarding me for a moment or two before likewise moving off.

After I got home, just at dusk, I looked out my kitchen window and saw yet another hawk perched in our peach tree — the one we haven't gotten a peach from in years because of our resident squirrels. This one we've come to think of as an old friend, as we see it in our yard almost every day, and the same or similar hawk has been visiting in the winter for years. It lingered only for a moment, then flew off.

Ode



The larger the scale, the more predictable the world is. The planets and stars move on determined courses, the earth revolves, day becomes night, the seasons change, all obeying established patterns. The closer you focus, the murkier it becomes. Will it rain tomorrow? Will it be a harsh winter? Will the breeze blow down the last leaf this morning, or the next?


And then there are phenomena — things appearing to view. We can predict comets — some of them, at least — but not every flash of a meteor shower. We can't be sure of the consequences of all of our own actions, though with some the baneful results are easy enough to foresee. And why does a bird appear one evening, and not the next? They obey their own unknowable laws, and cross through our vision only by accident.


And yet that's too facile. We ourselves are on unpredictable courses, and our fellow beings are inextricably mixed up in ours, for better or worse. The bird at top is no wild thing but someone's racing pigeon, and bears a band of human possession. I saw it two days in a row at the same location on the summit of a nearby dam. It showed no fear of me, and perhaps was lost, or maybe it was just resting before heading home. On the third day it was gone.


As for the last creature, I found it on its back, not far from the dove, and set it aright, for someone else to ponder.

Gulley Jimson & Co.



Because summer means going to the beach, and going to the beach means gulls.
