A closing circle

The silver Swan, who, living, had no Note,
   when Death approached, unlocked her silent throat.
Leaning her breast upon the reedy shore,
   thus sang her first and last, and sang no more:
“Farewell, all joys! O Death, come close mine eyes!
More Geese than Swans now live, more Fools than Wise.”

-Orlando Gibbons/Christopher Hatton 1612

 

December 2nd: high 36ºF, low 29ºF. Previous day’s high, an unseasonable but welcome 61ºF. Condition of pond: open water throughout, after complete disappearance of skim ice formed in late November. Mute swans active:

December 8th: high 24ºF, low 14ºF, after a 17ºF night. Solid overcast, steady high winds. Condition of pond: almost completely frozen over (though thinly; this isn’t yet the beginning of walkable, skateable ice); wisps of dusty snow blow into traceries that sweep and shift. Mute swans active, but constrained. With a nod to the opening of Citizen Kane:

Far out from the sheltering banks—

DSCF3193fp

even further than that—

DSCF3194fp

is a tiny pool of open water where

DSCF3195fp

a pair of swans paddle in convergent orbits for hours as day and light also decline. Whence this puddle? Perhaps a stable channeling or vorticity in the steady wind keeps the surface agitated at that spot. Perhaps an underground spring, as some allege to feed the pond; or the pumping action of pressure changes across its length. Perhaps the birds themselves provide enough motion to prevent gelation.

The swans dip, swallow and preen, as swans are wont to do. Mostly, they keep their heads down; wind chill in these conditions may be more of a problem than the relatively balmy and more-or-less invariant 55° water. But a little after the time of (unnoticeable) sunset, temperature and wind conspire to close the diner completely, and they flee—perhaps to the river, where there will be open water in far deeper chills than this.

Stalking alone

Hear and attend and listen; for this befell and behappened and became and was, O my Best Beloved, when the Tame animals were wild. … and they walked in the Wet Wild Woods by their wild lones. But the wildest of all the wild animals was the Cat. He walked by himself, and all places were alike to him.

Just So Stories, Rudyard Kipling

 

Wolves and other canines hunt in packs. Cats, in the main, prefer their own company. There are advantages to each. This magnificent buck, shown here napping in a soft bed

DSCN9463fp

after a light meal of sunflower seeds and cracked corn, was top dog deer around Flying Squirrel Hollow for several winters in succession until taken one midnight—following what was probably a mutually exhausting chase—by a loud pack of coyotes.

The victors apparently divided the spoils for private dining around the neighborhood, leaving this grisly souvenir near where the photo above was taken:

DSCF3186fp

A couple of decades prior, feral cats were a common sight in the area. Sometimes mangy, sometimes sleek, always distrustful of humans and clearly at home in their territory, they may contribute significantly to the decline of some songbirds hereabouts: while estimates are variable and controversial, it seems that at least several hundred million US birds are taken by feral and outdoor housecats. So, with due sympathy for the circumstances of pets forced to regress to a level of self-reliance against which they have been bred for several thousand years, not all mourn the recent confluence of coyote and cat.

Nonetheless, a few individuals survive, through greater wile, sharper senses or some other beneficial selection or adaptation. One such, seen for a few years in the area, is this confident but highly solitary individual:

With compassion for its victims, one may still respect and admire the hardy loner.

Flights of fancy

Farrar Pond hosts resident Canada geese (Branta canadensis) from spring’s first persistent open water to final closure a few weeks from now, and much larger populations of transients as the seasons shift. Harold here offers us some fine shots of geese on the wing.

While geese cannot soar great distances at perfect rest, as can gyrating scavengers like the buzzard (utilizing thermal lifts) or extreme sea voyagers like the albatross (near-surface wind shear), they do fly efficiently, with a glide ratio estimated around 20:1. There is a widespread factoid—based on sound but highly approximate calculations and then over-generalized—that by flying just so in V-shaped “skeins” the flock can fly 71% further than individuals could alone with the same energy expenditure. A more cautious view, which includes an above-average explanation of how formation flyers can benefit from wingtip vortex shedding of those ahead to mitigate induced drag may be found here. And similar benefits are posited for coordination instinctive in schooling fish and calculated for wind farms.

Antiparallel to Beltane, the cross-quarter holy day of Samhain marks the short tail of a scenic transition between riotous color and the muted browns and greys of the long half-light. Most birds and mammals

have put aside their flashy meeting-and-mating duds in favor of being invisible to increasingly motivated predators. Arthropods in the main, with perhaps the widest range of chromatic mechanisms of any life-form, are flown away, in mulchy retreat, or still better camouflaged. Or indoors, when warmth and food still prevail:

that did, indeed, attract a large mammalian customer who enjoyed sticky-sweet flesh and parked sucked-clean seed in the refrigerator for winter stratification and spring planting.

The fruit of this Asian bitter orange are entirely inedible by humans—their juice even curdles gin—

but make a decent marmalade that takes well to dark-chocolate couverture, if not already harvested by the next cross-quarter day—dread Imbolc—when not much else remains to sustain sciurid life.

In chromatic opposition but equally unpalatable to us is the Early Amethyst beautyberry:

And speaking of royal purple, the ancient “Queen of Trees”—magnolia—delivers a fruit to match its magnificent flower, large cones of bright red or orange seed that hang down on long threads when fully ripe to present themselves to birds and small mammals:

until even hoar departs, leaving emptier shadows of life past that will, on the same roots or new, eventually return from the grave.

A bounty of orchids

Lincoln is blessed with so many wonderful wildflowers that it is almost fortunate that our showiest local orchid, the pink lady’s slipper, is rare enough not to outshine the rest. By another of its monikers, it became the eponym for Moccasin Hill, one of Modernist neighborhood Brown’s Wood’s crossing ways. (The other is Laurel Drive, for another spectacular native, Kalmia latifolia.)

The lady’s slipper is noted for its particularity of habitat, requiring a mycorrhizal helper to germinate (and to survive when dormant), very acidic soil and just the right amount of light to thrive. It is also sparing of its graces; while plants may survive for a century or more, they only leaf in favorable years and flower not always then. Difficult to propagate by usual methods, expensive in the trade, it is occasionally poached from the wild—like this example of which Harold says: “Someone has stolen this lady’s slipper from along the Farrar Pond trail. The first to appear, it has bloomed at the same spot for over 20 years. Now it is gone forever. Shame on the perpetrator!”

Before   After

And doubly sad, the fragility of root structures means that few pilfered plants will survive captivity anyway. This selfish act, stealing delight from people and food from a number of other animals, is also illegal:

No person shall pull up or dig up the plant of a wild azalea, wild orchid or cardinal flower (lobelia cardinalis), or any part thereof, or injure any such plant or any part thereof except in so far as is reasonably necessary in procuring the flower therefrom, within the limits of any state highway or any other public way or place, or upon the land of another person without written authority from him, and no person shall buy or sell, or offer or expose for sale, any such flower, or the whole or any part of the plant thereof, knowing, or having reasonable cause to believe, that in procuring such flower or plant the foregoing provisions have been violated. Violation of any provision of this section shall be punished by a fine of not more than five dollars.

Though now risible, the size of the fine is consonant with the seniority of this law (1935), and the relatively early awareness that private depredations on public land were degrading natural beauty belonging to all. Please leave these too-rare gems to live, grow and spread!

Bird shower

Birds baths, when available, are a year-round boon to all sorts of winged and surface-bound visitors and permanent residents. Where the vigor with which an oriole

S0248036fpexploits this elevated puddle might encourage the pathetic fallacy of imputing decadent delight, such a “deep scrub” is critical to the maintenance of feather condition and the control of mites and other parasites. Yet activity around these small ponds can be hyper indeed, especially in times and places of scarce moisture, high social activity or territorial assertion:

S0042133fp

On the subject of low water, austerity measures imposed by state authority and refined in administration by Lincoln’s own Water Department (for an interesting read, see also the per-address usage tables posted there) mandate broad reductions in non-essential use. Since tubs require such a large fill volume for so little actual consumption, avian bathers are duty-bound to respect the same guidelines as their human benefactors. Fortunately, low-cost photovoltaic cells and high-energy product rare earth permanent magnet motors (both increasingly monopolized by China) converge in the ready availability of fixed or floating “solar fountains” in various configurations:

An additional benefit from adding this feature to a bird bath is that mosquitoes seem unwilling to lay eggs in their presence. Apparently, egg deposition does not occur at night, when the spray is dormant. This does not apply to larger bodies of water,

S0944576fp

Shallow pool

but the fish, tadpoles, turtles, dragonfly nymphs and other carnivores that more natural ponds usually host can make quick work of both eggs and wrigglers (ad even low-hovering mosquito mothers).

If a saucer is used, it should be wide enough to contain most of the spray even in a gentle wind, and deep enough not to require frequent filling:

S0035011fp

Rocks provide stability for the bath, a beach between dips

S0996270fp

and filler to maintain depth when most water has splashed out or evaporated. The area required for bathing per se is quite modest:

S0047019fp

Here will be dragons

Living near water offers diverse benefits to birders, boaters and bathers—the last not so much at Farrar Pond, where swimming is prohibited. Also costs; a major one, with shallow ponds and marshy edges, is the rapid breeding therein of contagion-bearing whining bloodsuckers.

Lao Tzu reminds us that when any force or movement becomes powerful, its counter also manifests. The same swampy water that attracts fecund mosquitoes and other unwelcome winged pests supports a varied population of creatures that thrive on their eggs and larvae. Baby turtles, tadpoles and fish all favor this high-protein food source. Among the most aggressive, taking tadpoles and minnows as well as smaller prey, are the naiads—obligate aquatic larvae—of order Odonata (“toothed ones”): dragonflies and damselflies. As top predators among aquatic arthropods, they rival the enormous but more delicately built water scorpions (Renata sp.):

P1080515fp

Naiads, usually concealed in the submerged jungle, may be seen as they cautiously emerge to split and dry on a reed or other protrusion, lifting themselves toward adulthood. Wings dry, they become fierce and effective aerial hunters, clearing the air of more undesirable insects than any bug-zapper ever could. Elegant in flight or at rest, they tolerate the close approach of slowly moving humans, and will even land on us to chew down a bug that may be almost as large as themselves. Stand in a sunny meadow with a finger pointed skyward, and they may come to perch between hunting forays.

Though themselves a rich meal and often brightly colored, iridescent or reflective, odonates are relatively safe in flight: their unpredictable jerky motion and panoramic compound vision

DSCF0194fp

(note solar and camera-flash reflections from patches among thousands of hexagonally close-packed ommatidia)

DSCF0194fp2

make them difficult for a swooping bird to track and intercept. And though considered by some a canard, their ability to operate fore-wings independently of those aft

S0032260fp

gives them aerial agility and multi-axis maneuverability exceeding even the hummingbird. Nonetheless, a close inspection of dragonfly hunting grounds shows how much they are themselves hunted, with beaked-off wings lightly scattered everywhere. Nor can their substantial translucence defend against that of of a common near-surface hazard;

DSCF1680fp

unlike their artificial brethren, these do not wield a wire-cutter.

At rest, they are more vulnerable, and to a broader range of predators. So beyond transparency, various camouflage strategies (like disruptive coloration, substrate mimicry and countershading) come into play. Adding species self-identification cues, the resulting shows of color are exceptional even among insects. A few more in situ examples of the hundred-plus found hereabouts, guiding the eye to subtle complexity, grand recursion and even enlightenment:

And how closes the cycle of life? With eggs. In a seldom-seen dance, this female hovers over a half-submerged nymphaea pad, repeatedly dipping her tail to wash eggs into the smaller pool. The success of this hands-off approach to breeding will make itself known come spring.

When ripe, the seeds of this pseudocereal may be harvested for a delicious and nutritious dish, or saved to plant for next year’s enjoyment by garden guests.

while the tiny flowers attract pollinators and perhaps predators
