Part 4 (2/2)
Far above the flock floated what seemed a fleck of white cloud blown up from the lower levels. As it drifted swiftly down toward the speeding plover, it grew into a great bird spa.r.s.ely mottled with pearl-gray, whose pointed wings had a spread of nearly five feet.
Driven down from Greenland by cold and famine, a white gyrfalcon was haunting these solitudes like some grim ghost of the upper sky. His fierce eyes were of a glittering black, as was the tip of his blue hooked beak.
As the plover whizzed southward on their way to Summer, some shadow of the coming of the falcon must have fallen upon them; for suddenly the whole flock broke and scattered through the sky, like a dropped handful of beads, each bird twisting and doubling through the air, yet still shooting ever southward at a speed which few other flyers could have equaled. Unluckily for the plover, the gyrfalcon is perhaps the fastest bird that flies, and moreover it has all of that mysterious gift of the falcon family of following automatically every double and twist and turn of any bird which it elects to pursue. This one chose his victim, and in a flash was following it through the sky. Here and there, back and forth, up and down, in dizzy circles and bewildering curves, the great hawk sped after the largest of the plover. As if driven in some invisible tandem, the white form of the falcon kept an exact distance from the plover, until at last the latter gave up circling and doubling for a stretch of straight flight. In an instant, the flas.h.i.+ng white wings of the falcon were above it; there was the same arrowy pounce with which the lesser falcon had struck down the teal; and, a moment later, the gyrfalcon had caught the falling body, and was volplaning down to earth with the dead plover in its claws.
For a time after this tragedy the sky seemed empty, as the scattered plover pa.s.sed out of sight, to come together as a flock many miles beyond. Then a mult.i.tude of tiny black specks showed for an instant in the blue. They seemed almost like motes in the sunlight, save that, instead of dancing up and down, they shot forward with an almost inconceivable swiftness. It was as if a stream of bullets had suddenly become visible. Immeasurably faster than any bird of even twice its size, a flock of ruby-throated humming-birds, the smallest birds in the world, sped unfalteringly toward the sunland of the South. Their buzzing flight had a dipping, rolling motion, as they disappeared in the distance on their way to the Gulf of Mexico, whose seven hundred miles of treacherous water they would cover without a rest.
As the setting sun approached the rim of the world, the lower clouds changed from banks of snow into ma.s.ses of fuming gold, splashed and blotched with an intolerable crimson. Again the sky was full of birds.
Those last of the day-flyers were the swallow-folk. White-bellied tree swallows; barn swallows, with long forked tails; cliff swallows, with cream-white foreheads; bank and rough-winged swallows, with brown backs--the air was full of their whirling, curving flight. With them went their big brothers, the purple martins, and the night hawks, with their white-barred wings, which at times, as they whirled downward, made a hollow tw.a.n.ging noise. With the flock, too, were the swifts, who sleep and nest in chimneys, and whose winter home no man yet has discovered.
As the turquoise of the curved sky deepened into sapphire, a shadowy figure came toward the circling, flas.h.i.+ng throng of swifts and swallows. The newcomer's great bare wings seemed made of sections of brown parchment jointed together unlike those of any bird. Nor did any bird ever wear soft brown fur frosted with silver, nor have wide flappy ears and a hobgoblin face. Miles above the ground this earth-born mammal was beating the birds in their own element. None of the swallows showed any alarm as the stranger overtook them, for they recognized him as the h.o.a.ry bat, the largest of North American bats, who migrates with the swallows and, like them, feeds only on insects.
As the sun sank lower, the great company of the bird-folk swooped down toward the earth, for swallows, swifts, and martins are all day-flyers. Not so with the bat. In the fading light, he flew steadily southward alone--but not for long. Up from earth came again the great gyrfalcon, his fierce hunger unsatisfied with the few mouthfuls torn from the plover's plump breast. As his fierce eyes caught sight of the flitting bat, his wings flashed through the air with the same speed that had overtaken the plover. No bird that flies could have kept ahead of the rush of the great hawk through the air.
A mammal, however, is farther along in the scale of life than a bird, and more efficient, even as a flyer. As the p.r.i.c.ked-up ears of the bat caught the swish of the falcon's wings, the beats of its own skin-covered pair increased, and the bird suddenly ceased to gain.
Disdaining to double or zigzag, the great bat flew the straightaway race which the falcon loves, and which would have meant quick death to any bird who tried it. Skin, however, makes a better flying surface than feathers, and slowly but unmistakably the bat began to draw away from its pursuer. The gyrfalcon is the speed-king among birds, but the h.o.a.ry bat is faster still. Five, ten, fifteen minutes pa.s.sed before the hawk realized that he was being outflown. Increase his speed as he would, the bat, in an effortless nonchalant manner, moved farther away. When only a streak of silver sky, with a shoal of little violet clouds, was left of the daylight the gyrfalcon gave up the chase. As he swooped down to earth like a white meteor, the brown figure of the bat disappeared in the violet twilight, beating, beating his way south.
As the sky darkened to a peac.o.c.k-blue, and a faint amber band in the west tried to bar the dark, suddenly the star-s.h.i.+ne was full of soft pipings and chirpings. The night-flyers had begun their journey, and were calling back and forth heartening each other as they flew through the long dark hours. Against the golden disc of the rising moon a continuous procession of tiny black figures showed the whole sky to be full of these pilgrims from the north. The ”c.h.i.n.k, c.h.i.n.k” of the bobolinks dropped through the stillness like silver coins; and from higher up came the ”tsip, tsip, tsip” of the black-poll warblers, all the way from the Magdalen Islands. With them were a score or so of others of the great warbler family. Black-throated blues, Cape Mays, redstarts, golden-wings, yellow warblers, black-throated greens, magnolias, myrtles, and tiny parulas--myriads of this many-colored family were traveling together through the sky. With them went the vireos, the orioles, the tanagers, and four different kinds of thrushes, with a dozen or so other varieties of birds following.
Most of them had put on their traveling clothes for the long journey.
The tanagers had laid aside their crimson and black, and wore yellowish-green suits. The indigo bird had lost his vivid blue, the rose stain of the rose-breasted grosbeak was gone, along with the white cheeks of the black-poll warbler and the black throat of the black-throated green, while the bobolinks wore sober coats of olive-buff streaked with black, in place of their cream-white and velvet black.
Once during the night, as the army crossed an Atlantic cape, a lighthouse flashed its fatal eye at them. Immediately the ranks of the flyers broke, and in confused groups they circled around and around the witch-fire which no bird may pa.s.s. For hours they flew in dizzying circles, until, weary and bewildered, some of the weaker ones began to sink toward the dark water. Fortunately for them, at midnight the color of the light changed from white to red. Instantly the prisoners were freed from the spell which only the white light lays upon them, and in a minute the air was filled with glad flight-calls, as the released ranks hurried on and away through the dark.
All night long they flew steadily, and turned earthward only at sunrise. As the weary flyers sought the trees and fields for rest and food, overhead, against a crimson and gold dawn, pa.s.sed the long-distance champion of the skies--the Arctic tern, with its snow-white breast, black head, curved wings, and forked tail. Nesting as far north as it can find land, only seven and a half degrees from the Pole, it flies eleven thousand miles to the Antarctic, and, ranging from pole to pole, sees more daylight than any other creature.
For eight months of its year it never knows night, and during the other four has more daylight than dark. Scorner of all lands, tireless, unresting, this dweller in the loneliest places of earth flashed white across the dawn-sky--and was gone.
V
THE LITTLE PEOPLE
The swamp-maples showed rose-red and gold-green in the warm sunlight, and the woods were etched lavender-brown against a heliotrope sky. The bluebird, with the sky-color on his back and the red-brown of earth at his breast, called, ”Far-away! far-away! far-away!” in his soft sweet contralto. From a wet meadow a company of rusty blackbirds, with short tails and white eyes, sang together like a flock of creaking wheelbarrows, with single split notes sounding constantly above the squealing chorus. Beyond the meadow was a little pool, where the air was vibrant with the music of the frogs. The hylas sang like a chest of whistles so shrill that the air quivered with their song. At intervals, a single clear flute-note rose above the chorus, the love-call of the little red salamander; while the drawling mutter of cricket-frogs, the trilled call of the wood-frogs, and the soft croon of the toad added delicate harmonies. Near-by a song-sparrow sang wheezingly from a greening willow tree, but its note sounded flat compared with the shrill, high sweetness of the batrachian chorus.
Near the top of Prindle Hill was a dry warm slope, with stretches of underbrush, pasture, and ledges of rock rising to the patch of woods which crowned the crest of the hill. Beyond was a tiny lake.
Everywhere along the sunny slope were small round holes bored through the tough turf. As the sun rose higher and higher, little waves of heat penetrated deep below the gra.s.s-roots.
Suddenly, from out of one of the holes, a little pointed nose was thrust, and a second later the first chipmunk of the year darted above ground from the burrow where he had slept out the long winter. His dark pepper-and-salt colored back had a black-brown stripe down the centre and four others in pairs along either side, separated by strips of cream-white. His cheeks, flanks, feet, and the underside of his black fringed tail were of a light fawn-color, and he wore a silky white waistcoat. Erecting his white-tipped tail, he sat up on his haunches and tipping back his head, began to sing the spring song which every chipmunk must sing when he first comes above ground at the dawn of the year. ”Chuck-a-chuck-a-chuck-a-chuck-a-chuck,” he chirped loudly, at the rate of two chirps per second.
At the very first note sharp noses and bright black eyes appeared at every hole, and in a second a score or more other singers had whisked out and joined in the spring chorus, each one bent on proving that his notes were the loudest and clearest of any on the hill. One of the last to begin was a half-grown chipmunk, who had been crowded out of the family burrow by new arrivals the autumn before. Fortunately for him, however, the next burrow was occupied by a chipmunk of an inquiring disposition. Said disposition caused him to wait to investigate the habits of a pa.s.sing red fox. Thereafter his burrow was to let, and was immediately taken possession of by the young chipmunk aforesaid.
This new tenant came out timidly, even when he felt the thrill of spring. Once above ground, however, he simply had to sing. At his very first note, he sensed a difference between his voice and those of all the others. Whereas they sang ”Chuck-a-chuck-a-chuck,” he sang ”Chippy, chippy, chippy.” To his delighted ear his own higher notes were far superior to those of his companions, and he shrilled away, ecstatically, with half-closed eyes. Ten minutes went happily by. Then a singer on the outskirts caught sight of a marsh-hawk quartering the hillside, and gave the alarm-squeal as he dove into his hole. The song broke in the middle, as every singer whisked underground and the annual spring song was over. Thereafter the customary caution of a chipmunk-colony was resumed.
At first, Chippy ventured but seldom outside of his new burrow. Far in under the turf was the storehouse, filled by its first owner full of hazel-nuts, cherry-pits, wild buckwheat, b.u.t.tercup seeds, maple-keys, and other chipmunk staples, all carefully cleaned, dried, and stored.
