Looking for birds along the Pipeline Road . . .

We were supposed to head to Parque Nacional Soberanía the day after we exhausted ourselves hiking at  Parque Natural Metropolitano and then walking to Casco Viejo. Fortunately, we had to postpone our trip by a day because it was raining so hard. It gave us some much needed time to rest and we enjoyed an excellent meal of sushi and maracuyá sangria.

The next morning, we were up early and on our way to Soberanía with our guide, Miguel Ibarra (@nature_guide_panama on Instagram of Panama Road Trip Adventures. I highly recommend him!), one of the most accessible tropical rainforests in Panamá.

We hiked down the Pipeline Road, mostly in search of birds as the park is home to 525 species and holds the Guinness World Record for most species sighted in a day–nearly 400. I was lucky enough to be the first to spot a southern mealy amazon parrot perched high in a tree.

While one of the largest amazonian parrots at 15-17 inches length, the mealy parrot is rarely spotted except when flying.

I was fortunate enough to be able to grab a photo through Miguel’s telescope. My husband, Frank, was lucky enough to grab a shot of this anteater crossing the Pipeline Road:

This anteater is one of 105 species of mammals in the park.

We also saw agoutis, caiman, and heard howler monkeys, among other things. But what I found truly interesting was the termites, which are essential to the rainforest biome.

Miguel exposed part of the “termite highway” to show us the activity beneath.

The “highway” runs the length of the tree.

Recent research has discovered that termites are actually modified roaches with the oldest fossils being found in the Lower Cretaceous period (145-99 million years ago!), which makes them the oldest social animals currently alive. Who knew?

These Central American termites is the second largest species in richness but less researched than the termites of Africa and Europe. In the rainforests, termites build large mounds, usually on trees. These termites are particularly adept at breaking down the cellulose from dead wood in the soil because they have the highest gut Ph in the world at more than 12. This makes it possible for the termites to explore the thick humus layers under tropical rainforest canopies. We also got to see the unique relationship between bees and ants, which nest near each other.

This Psychotria elata is a plant native to Central and South America, which is slowly disappearing due to deforestation.

This striking flower is not actually a flower but bracts, or modified leaves. Tiny, star-shaped flowers will eventually grow from the center of the red leaves. The plant is also known as Hot Lips, Mick Jagger Lips, or, as Miguel updated it, Angelina Jolie Lips.

Group photo with Miguel, Frank and myself, and our daughter, Griffin.

Did I say that we also saw lots of toucans and hummingbirds? Butterflies, frogs, and caterpillars? A dead caiman with a basilisk or Jesus lizard (because it can walk on water) resting on its exposed belly? A live caiman carrying a plastic grocery bag full of intestines?

We decided that day that if we just saw one unexpected thing (three that morning) each time we went out, it would be enough. Dayenu.

A Sand County Almanac, Aldo Leopold, Environment, Wisconsin

By Charles W. Schwartz

It’s December in A Sand County Almanac, and Aldo Leopold is musing on a few subjects. He begins by discussing how he is curious about learning about an animal’s home range through its actions.

“A sudden yip-yip-yip gives us notice that a rabbit,” he writes, “flushed from his bed in the grass, is headed elsewhere in a hurry. He makes a bee-line for a woodpile a quarter-mile distant, where he ducks between two corded stacks, a safe gunshot ahead of his pursuer.”

“This little episode tells me,” he writes a little later, “that this rabbit is familiar with all of the ground between his bed in the meadow and his blitz-cellar under the woodpile. How else the bee-line? The rabbit’s home range is at least a quarter mile in extent.

“The chickadees that visit our feeding station are trapped and banded each winter,” he continues, then writes, “By noticing the furthest points from my feeder at which banded chickadees are seen, we have learned that the home range of our flock is half a mile across in winter, but that included only areas protected from wind.

“In summer, when the flock has dispersed for nesting, banded birds are seen at greater distances . . .”

Leopold then moves on to deer, noting the fresh tracks of three deer he noticed in the previous day’s snow, which he follows backward to discover a cluster of three beds, clear of snow, in the big willow thick on the sandbar. He then follows the tracks forward.

“My picture of the night’s routine in complete. The over-all distance from bed to breakfast is a mile.”

Grouse, he discovers, for the duration of a soft snow (which would show tell-tale tracks), cover their home range a-wing and not afoot, and range was half a mile across.

“Science knows little about home range,” he writes, but concludes, “Every farm is a textbook on animal ecology; woodsmanship is the translation of the book.”

White Pine

Next Leopold turns to pines, one of his favorite trees.

“The pine’s new year begins in May,” he writes when the terminal bud become ‘the candle’. Whoever coined that name for the new growth had subtlety in his soul. ‘The candle’ sounds like a platitudinous reference to obvious facts: the hew shoot is waxy, upright, brittle. But he who lives with pines knows that the candle has a deeper meaning, for at its tip burns the eternal flame that light a path into the future.”

If by June 30th of that year, the pine’s completed candle has developed a terminal cluster of ten or twelve buds, it means that it as stored away enough sun and rain for a two- to three-foot thrust skyward the following spring. Four to six buds mean a shorter spurt of growth.

Hard years can be seen as shorter spaces between successive whorls of branches.

Leopold claims that much can be divined from pines, “in March, when the deer frequently browse white pines, the height of the browsing tells me how hungry they are.”

A full deer, for example, will nip at branches no more than four feet from the ground while a really hungry deer will stand on its hind legs to crop at the branches as high as eight feet above the ground.

By May, Leopold says that when he finds wilted candles lying in the grass, he knows that a bird has alighted on it and broken it off.

“It is easy to infer what has happened,” he writes, “but in a decade of watching I have never once seen a bird break a candle. It is an object lesson: one need not doubt the unseen.”

In June, some candles wilt and turn brown before dying.

“A pine weevil has bored into the terminal bud cluster and deposited eggs;” he explains, “the grubs, when hatched, bore down along the pith and kill the shoot.”

Leopold also notes that only pines in full sunlight are bitten by weevils; those in the shade remain unscathed.

In October, bucks are beginning to rub their antlers against the trees, rubbing the bark from the trees as they rub the velvet from their antlers.

“The three species of pine native to Wisconsin (white, red, and jack) differ radically in their opinions about marriageable age,” he writes.

The jack pine sometimes blooms and bears cones a year or two after leaving Leopold’s nursery.

“My 13-year-old reds first bloomed this year,” he writes, “but my whites have not yet bloomed; they adhere closely to the Anglo-Saxon doctrine of free, white and twenty-one.”

Leopold remarks that each year in midsummer, the red squirrels tear up the jackpine cones for seeds, “under each tree the remains of their annual feast lie in piles and heaps.”

“Pines, like people,” he writes, “are choosy about their associates and do not succeed in suppressing their likes and dislikes. Thus there is an affinity between white pines and dewberries, between red pines and flowering spurge, between jackpines and sweet fern.”

Each species of pine also has its own constitution, he says. “which prescribes a term of office for needles appropriate to its way of life. Thus the white pine retains its needles for a year and a half; the red and jackpines for two years and a half. Incoming needles take office in June, and outgoing needles write farewell addresses in October.”

banded chickadee by Charles W. Schwartz

“65290” is the final segment in this chapter.

“To band a bird is to hold a ticket in a great lottery,” Leopold writes. “It is an exercise in objectivity to hold a ticket on the banded sparrow that falleth, or on the banded chickadee that may some day re-renter your trap; and thus prove that he is still alive.”

Leopold says that, “the real thrill lies in the recapture of some bird banded long ago, some bird whose age, adventures, and previous condition of appetite are perhaps better known to you than to bird himself.

“Thus in our family, the question whether chickadee 65290 would survive for still another winter was, for five years, a sporting question of the first magnitude.”

65290 was one of seven chickadees constituting what Leopold calls the ‘class of 1937’.

“By the second winter our recaptures showed that the class of 7 had shrunk to 3, and by the third winter to 2. By the fifth winter 65290 was the sole survivor of his generation.”

“During his sixth winter 65290 failed to reappear, and the verdict of ‘missing in action’ is now confirmed by his absence during four subsequent trappings.

“At that, of 97 chicks banded during the decade,” Leopold concludes, “65290 was the only one contriving to survive for five winters.”

“I know so little about birds,” Leopold continues later, “that I can only speculate on why 65290 survived his fellows. Was he more clever in dodging his enemies? What enemies? A chickadee is almost too small to have any.”

Musing on that, Leopold notes, “The sparrow hawk, the screech owl, the shrike, and especially the midget saw-whet owl might find it worth while to kill a chickadee, but I’ve only once found evidence of actual murder: a screech owl pellet containing one my bands.”

“It seems likely,” he continues, “that weather is the only killer so devoid of both humor and dimension as to kill a chickadee. I suspect that in the chickadee Sunday School two mortal sins are taught: thou shalt not venture into windy places in winter, thou shalt not get wet before a blizzard.”

Many birds, not just chickadees seem leery of the wind, for as Leopold notes, “Wind from behind blows cold and wet under the feathers, which are his portable roof and air conditioner. Nuthatches, juncos, tree sparrows and woodpeckers likewise fear winds from behind, but their heating plants and hence their wind tolerance are larger in the order named.”

Leopold ends the chapter with what he considers the third commandment: “thou shalt investigate every loud noise.”

Why? Because falling trees expose the chickadee delicacy: ant eggs.

A Sand County Almanac, Aldo Leopold, Conservation, Trees, Wisconsin

by Charles W. Schwartz

In A Sand County Almanac, Aldo Leopold begins his chapter on November with a discussion of the wind and its sound and effects on the landscape and its inhabitants. This brief discussion is followed by a lengthy discourse on trees and his thoughts behind whether they should be axed or not.

“I have read many definitions of what is a conservationist,” he writes, “and written not a few myself, but I suspect that the best one is written not with a pen, but with an axe. It is a matter of what a man thinks about while chopping, or while deciding what to chop. A conservationist is one who is humbly aware that with each stroke he is writing his signature on the face of his land. Signatures, of course, differ, whether written with axe or pen, and this is as it should be.”

Later, he adds, “The wielder of an axe has as many biases as there are species of trees on his farm. In the course of the years he imputes to each species, from his responses to their beauty or utility, and their responses to his labors for or against them, a series of attributes that constitute a character. I am amazed to learn what diverse characters different men impute to one and the same tree.”

He goes on to name some examples–why he likes aspens (they glorify October and feed his grouse in winter) and his neighbor thinks of it as a weed (because it grows so well in land that was meant to be cleared). He discusses tamaracks, cottonwoods, wahoos, red dogwood, bittersweets,  and hickories, as well.

by Charles W. Schwartz

“It is also evident that our plant biases reflect not only vocations but avocations,” he writes, “with a delicate allocation of priority as between industry and indolence. The farmer who would rather hunt grouse than milk cows will not dislike hawthorn, no matter if it does invade his pasture. The coon-hunter will not dislike basswood, and I know of quail hunters who bear no grudge against ragweed, despite their annual bout with hayfever. Our biases are indeed a sensitive index to our affections, our tastes, our loyalties, our generosities, and our manner of wasting weekends.”

He then writes: “Every farm woodland, in addition to yielding lumber, fuel, and posts, should provide its owner a liberal education. This crop of wisdom never fails, but it is not always harvested. I here record some of the many lessons I have learned in my own woods.”

Leopold realized soon after he purchased his woods that he had “bought almost as many tree diseases” as he had trees. “But it soon became clear,” he writes, “that these same diseases made my woodlot a mighty fortress, unequaled in the whole county.

“My woods is headquarters for a family of coons; few of my neighbors have any.”

Why? Because a fallen and diseased tree on his property became a safe haven against coon hunters.

“The hunter had quit coonless because a fungus disease had weakened the roots of the maple. The tree, half tipped over by a storm, offers an impregnable fortress for coondom. Without this ‘bombproof’ shelter, my seed stock of coons would be cleaned out by hunters each year.”

He continues with more examples:

Oaks wind-thrown by summer storms become a harbor for grouse during winter snows, keeping them safe from wind, owls, foxes, and hunters. The diseased oaks also provide oak galls, a favorite grouse food. Wild bees fill his hollowed oaks with honeycomb.

Rabbits, he says, spurn red dogwood until it is attacked by oyster-shell scale. And, when he is harvesting diseased or dead trees for fuel in the winter, “every slab of dead bark is, to them [chickadees], a treasury of eggs, larvae, and cocoons.”

“But for diseases and insect pests,” he writes, “there would likely be no food in these trees, and hence no chickadees to add cheer to my woods in winter.

“Many other kinds of wildlife depend on tree diseases,” he says. Pileated woodpeckers, barred owls, wood ducks, and squirrels all take advantage of diseases trees.

“The real jewel of my disease-ridden woodlot is the prothonotary warbler,” he concludes the chapter. “He nests is an old woodpecker hole, or other small cavity, in a dead snag overhanging water. The flash of his gold and blue plumage amid the dank decay of the June woods is in itself proof that dead trees are transmuted into living animals, and vice versa. When you doubt the wisdom of this arrangement, take a look at the prothonotary.”

A Sand County Almanac, Aldo Leopold, Autumn, October

by Charles W. Schwartz

It is October in Wisconsin and Aldo Leopold turns to the subject of the fall hunt. I have to admit that I have only been hunting once in my life and that was because I was doing a story for a daily newspaper on a hunting club.

They tried to fool this Girl Scout into thinking that golden raisins were deer scat, but I knew better. Once they realized I (my husband who was photographing the story had hunting experience) wasn’t a nature novice, I was treated with more respect and had a wonderful time. And I never told them that I was secretly pleased that no deer died by our hands that weekend.

But in A Sand County Almanac, Leopold reminisces about hunting for grouse and pheasants:

“There are two kinds of hunting:” he begins, “ordinary hunting and ruffed-grouse hunting.

“There are two place to hunt grouse: ordinary places, and Adams County.

“There are two times to hunt in Adams: ordinary times, and when the tamaracks are smoky gold.”

Smoky gold tamaracks

“The tamaracks change from green to yellow when the first frosts have brought woodcock, fox sparrows, and juncos out of the north,” he writes. “Troops of robins are stripping the last white berries from the dogwood thickets, leaving the empty stems as a pink haze against the hill. The creekside alders have shed their leaves, exposing here and there an eyeful of holly. Brambles are aglow, lighting your footsteps grouseward.”

Musing on an abandoned farm that he passes, Leopold becomes aware that his dog has  been “pointing patiently these many minutes.”

“I walk up,” he writes, “apologizing for my inattention. Up twitters a woodcock, batlike, his salmon breast soaked in October sun. Thus goes the hunt.”

Leopold then reflects on early risers, what he says is a “habitual vice in horned owls, stars, geese, and freight trains.”

by Charles W. Schwartz

“Some hunters acquire it from geese,” he continues, “and some coffee pots from hunters. It is strange that of all the multitude of creatures who must rise in the morning at some time, only these few should have discovered the most pleasant and least useful time for doing it.”

“Early risers,” he writes later, “feel at ease with each other, perhaps because, unlike those who sleep late, they are given to understatement of their own achievements. Orion [the constellation], the most widely traveled, says literally nothing. The coffee pot, from its first soft gurgle, underclaims the virtues of what simmers within. The owl, in his trisyllabic commentary, plays down the story of the night’s murders. The goose on the bar, rising briefly to a point of order in some inaudible anserine debate, lets fall no hint that he speaks with the authority of all the far hills and the sea.

“The freight, I admit, is hardly reticent about his own importance, yet even he has a kind of modesty: his eye is single to his own noisy business, and he never comes roaring into somebody else’s camp. I feel a deep security in this single-mindedness of freight trains.”

by Charles W. Schwartz

“One way to hunt partridge,” Leopold notes, “is to make a plan, based on logic and probabilities, of the terrain to be hunted. This will take you over ground where the birds ought to be.

“Another way is to wander, quite aimlessly, from one red lantern to another. This will likely take you where the birds actually are. The lanterns are blackberry leaves, red in October sun.”

Guess which is Leopold’s preferred method.

“Red lanterns,” he continues, “have lighted my way on many a pleasant hunt in many a region, but I think that blackberries must first have learned how to glow in the sand counties of central Wisconsin.”

The red lanterns of fall . . .

“At sunset on the last day of the grouse season,” Leopold concludes, “every blackberry blows out his light. I do not understand how a mere bush can thus be infallibly informed about the Wisconsin statutes, nor have I ever gone back the next day to find out. For the ensuing eleven months the lanterns glow only in recollection. I sometimes think that the other months were constituted mainly as a fitting interlude between Octobers, and I suspect that dogs, and perhaps grouse, share the same view.”

A Sand County Almanac, Aldo Leopold, Flowers

Field Sparrow

July has come to Dane County, Wisconsin, and Aldo Leopold begins the chapter with his daily (good weather) ceremony on his 120-acre farm:

“At 3:35 (a.m.),” he writes, “the nearest field sparrow avows, in a clear tenor chant, that he holds the jackpine copse north to the riverbank, and south to the old wagon track.”

Leopold then continues to describe the daily symphony of birdsong as they all call out their territories, ending with a bedlam of birdsong at dawn as grosbeaks, thrashers, yellow warblers, bluebirds, towhees, cardinals, make their claims. When the bird songs are no longer decipherable, Leopold heads out for his morning walk with his dog.

by Charles W. Schwartz

They never know what will turn up on their walk, Leopold notes. It could be a rabbit, a coon, or a mink; perhaps a deer returning to the thickets, a heron caught in the act of fishing, or a wood duck trailed by her ducklings. A tractor roaring to life recalls them to the fact they are not alone in this early morning world, and they return home for breakfast.

Most of the chapter on July is dedicated to the once ubiquitous prairie plant know as Silphium or Compass plant (because its leaves have an east-west orientation).

Silphium by Frank Mayfield

“Every July I watch eagerly a certain country graveyard that I pass in driving to and from my farm,” Leopold writes.

This cemetery is ordinary, he says, except, “It is extraordinary only in being triangular instead of square, and in harboring, within the sharp angle of its fence, a pinpoint remnant of the native prairie on which the graveyard was established in the 1840’s. Heretofore unreachable by scythe or mower, this yard-square relic of original Wisconsin gives birth, each July, to a man-high stalk of compass plant or cutleaf Silphium, spangled with saucer-sized yellow blooms resembling sunflowers.”

Leopold spies the blooms on July 24, a week later than normal, but when he drives by again, on August 3, the fence has been removed and the corner of the cemetery mowed down, along with the Silphium. He then laments the world in which, “Mechanized man, oblivious of floras, is proud of his progress in cleaning up the landscape on which, willy-nilly, he must live out his days.

He compares the number of wild plant species growing on this farm to those that grow in the suburbs and the university campus where he works–226 versus 120–the price of progress. We are confronted by two alternatives, he writes: “either insure the continued blindness of the populace, or examine the question whether we cannot have both progress and plants.”

“We grieve only for what we know,” he writes later.

by Charles W. Schwartz

“Why does Silphium disappear from grazed areas?” he asks, then posits, “I once saw a farmer turn his cows into a virgin prairie meadow previously used only sporadically for mowing wild hay. The cows cropped the Silphium to the ground before any other plant was visibly eaten at all. One can imagine that the buffalo once had the same preference for Silphium, but he brooked no fences to confine his nibblings all summer long to one meadow. In short, the buffalo’s pasturing was discontinuous, and therefore tolerable to Silphium.

“It is a kind of providence that has withheld a sense of history from the thousands of species of plants and animals that have exterminated each other to build the present world. The same kind of providence now withholds it from us. Few grieved when the last buffalo left Wisconsin, and few will grieve when the last Silphium follows him to the lush prairies of the never-never land.”

April

A Sand County Almanac, Aldo Leopold, Nature

By Charles W. Schwartz

“The same logic that causes big rivers always to flow past big cities causes cheap farms sometimes to be marooned by spring floods,” Aldo Leopold writes in his opening to his chapter on April. “Ours is a cheap farm, and sometimes when we visit it in April we get marooned.”

Later, he continues, “The enthusiasm of geese for high water is a subtle thing, and might be overlooked by those unfamiliar with goose-gossip, but the enthusiasm of carp is obvious and unmistakable. No sooner has the rising flood wetted the grass roots than here they come, rooting and wallowing with the prodigious zest of pigs turned out to pasture, flashing red tails and yellow bellies, cruising the wagon tracks and cow-paths, and shaking the reeds and bushes in their haste to explore what to them is an expanding universe.

“Unlike the geese and the carp, the terrestrial birds and mammals accept high water with philosophical detachment.”

Continuing on the subject of the April floods, Leopold writes, “The spring flood bring us more than high adventure; it brings likewise an unpredictable miscellany of floatable objects pilfered from upriver farms.”

Among those pilfered items are boards: “Our lumber pile, recruited entirely from the river, is thus not only a collection of personalities, but an anthology of human strivings in upriver farms and forests.”

“I know of no solitude,” he writes, “so secure as one guarded by a spring flood; nor do the geese, who have seen more kinds and degrees of aloneness than I have.”

Draba

Another April sign announcing the coming of spring is a small flower.

“Within a few weeks now Draba,” Leopold writes, “the smallest flower that blows, will sprinkle every sandy place with small blooms.”

He continues a bit later: “Draba plucks no heartstrings. Its perfume, if there is any, is lost in the gusty winds. Its color is plain white. Its leaves wear a sensible wooly coat. Nothing eats it; it is too small. No poets sing of it. Some botanist once gave it a Latin name, and then forgot it. Altogether it is of no importance–just a small creature that does a small job quickly and well.”

Bur Oak savanna in Wisconsin hill country.

“Each April before the new grasses had covered the prairie with unburnable greenery,” Leopold writes, “fires ran at will over the land, sparing only such old oaks as had grown bark too thick to scorch.” And thus a battle between the forest front and prairie was ignited, each vying for each other to take over the land.

Later, he continues, “But the average battle line between prairie and forest was about where it is now, and the net outcome of the battle was a draw.

“One reason for this was that there were allies that threw their support first to one side, then to the other. Thus rabbits and mice mowed down the prairie herbs in the summer, and in the winter girdled any oak seedlings that survived the fires. Squirrels planted acorns in fall, and ate them all the rest of the year. June beetles undermined the prairie sod in their grub stage, but defoliated the oaks in their adult stage.”

“In the 1840s,” he later writes, “a new animal, the settler, intervened in the prairie battle. He didn’t mean to, he just plowed enough fields to deprive the prairie of its immemorial ally: fire. Seedling oaks forthwith romped over the grasslands in legions, and what had been the prairie region became a region of woodlot farms.”

John Muir grew up during this era, and in his Boyhood and Youth he writes:

“The uniformly rich soil of the Illinois and Wisconsin prairies produced so close and tall a growth of grasses for fires that no tree could live on it. Had there been no fires, these fine prairies, so marked a feature of the country, would have been covered by the heaviest forest. As soon as the oak openings were settled, and the farmers had prevented running grass-fires, the grubs [roots] grew up into trees and formed tall-thickets so dense that it was difficult to walk through them, and every trace of the sunny [oak] ‘openings’ vanished.”

Woodcock

“I owned my farm for two years before learning that the sky dance is to be seen over my woods every evening in April and May,” Leopold writes.

“The show begins on the first warm evening in April at exactly 6:50 p.m. The curtain goes up one minute later each day until 1 June, when the time is 7:50.”

“The stage must be an open amphitheater in woods or brush,” he continues later, “and in its center there must be a mossy spot, a streak of sterile sand, a bare outcrop of rock or a bare roadway.”

And then: “Knowing the place and the hour, you seat yourself under a bush to the east of the dance floor and wait, watching against the sunset for the woodcock’s arrival. He flies in low from some neighboring thicket, alights on the bare moss, and at once begins the overture: a series of queer throaty peents spaced about two seconds apart, and sounding much like the summer call of the nighthawk.

“Suddenly the peenting ceases and the bird flutters skyward in a series of wide spirals, emitting a musical twitter. . . . Then, without warning, he tumbles like a crippled plane, giving voice in a soft liquid warble that a March bluebird might envy. At a few feet from the ground he levels off and returns to his peenting ground, usually to the exact spot where the performance began, and there resumes his peenting.

“It is soon too dark to see the bird on the ground, but you can see his flights against the sky for an hour, which is the usual duration of the show.”

Woodcock by Charles W. Schwartz

Leopold concludes: “The drama of the sky dance is enacted nightly on hundreds of farms, the owners of which sigh for entertainment, but harbor the illusion that it is to be sought in theaters. They live on the land, but not by the land.”
