Into the upper end of Chocorua Lake flows a brook of transparent water, fed by melting snows, out of “the heart of the mountain.” Along this the song of the water thrush leads the wanderer from one limpid pool to another, a song that has in it some of the liquid prattle of the stream but more of a dominant, aggressive note that carries far. There is a touch of sunlight in the color of the water thrush’s breast, sunlight flecked with little brown shadow markings that are like the uniform brown of his back, and if it were not that he sticks so closely to the water he might suggest the oven-bird to the careless glance. There is something of the song sparrow and the oven-bird at once in his song. It is as if the two birds had mated to produce him and the singing masters of both families had had the youngsters to singing school. Up this clear-water brook the oven-birds call you by way of the height of land, the water thrushes from pool to pool, while the sun drops behind Paugus in mid afternoon, and the blue shadows of the Sandwich range add to the cool gloom which wells upward from the deep gorge which is the heart of the mountains.
On the way, as the water thrushes and Maryland yellow-throats sing from the thickets near the water, so the oven-bird sends his aggressive staccato from the middle distances of the higher trees. I never knew an oven-bird to sing from either a treetop or a low thicket. Always he sits on a limb well up the trunk yet well beneath the shade also, and sends forth that aggressive, eager call for knowledge. “Teach us, teach us, teach us,” he cries to the wood gods, nor is he ever satisfied with his schooling, but applies persistently for more. The oven-bird is the very voice of the spirit of modern learning, crying always, in the wilderness of knowledge attained, for more knowledge. The wood gods have taught him much. Invisibility for himself he has almost learned. He sits like a knot on a speckled brown limb, and his speckled brown breast is so much like it that he may sing long there within a little distance of your eye before you see him. Invisibility for his nest he and his demure brown wife have learned completely. You may sit on it to rest among the brown leaves in the wood and not know it is there; unless the frightened escape of the brown mother birds gives you a hint, and even then it is invisible, so completely is it hidden in the debris dropped by the previous autumn. Of dead weed stalks, grasses and brown leaves it is not only built but roofed, and with an entrance on one side that to the uninitiated might be an entrance to the nest of a field mouse, indeed, but never that to a bird’s nest. It is not for greater knowledge of nest hiding that the oven-bird need pray to the wood gods, nor may we know what further wisdom he seeks, but all summer long he asks for it in no uncertain tones.
Out of the very treetops while the oven-bird shouts his prayer below comes the voice of the red-eyed vireo, uttering moral platitudes from dawn till dusk. It is no wonder that some birds go wrong with this monotonous preacher steadily droning out, “Don’t do this; don’t do that,” to them all day long. The bluejays, who have robber baron blood stirring always under their gaudy military coats, jeer at this prating of platitudes and descend upon the vireo’s hanging nest and eat the eggs from it, I always think, with more gusto than in their other freebooting, and small blame to them. The red-eyed vireo leads an exemplary life, no doubt, living properly on small insects and keeping up perpetual prayer-meeting, but his self-righteous twaddle must be intensely irritating to all but impeccably good birds that have to listen to it. In gladsome relief from this was the demeanor of the Canadian warblers, also flitting daintily in the treetops. I know the authorities say that the Canadian warbler frequents low thickets, but there is no mistaking the bird with his breast and throat of clear yellow and his necklace of jet beads, and this May the leafy topmost twigs of the deciduous trees in the Chocorua region held many such. They sang their liquid warble which has in it more than a suggestion of the song-sparrow notes of the water-thrush song, and they dashed out into the free air for insects which they captured, flycatcher fashion, and then dashed back again. The Canadian warblers are migrating, feeding and singing as they go on to their nesting sites farther north, and this year their favorite food must have been hanging high, for they were up there after it.
With the Canadians was the first wave of the tide of blackpolls which sweeps over the mountains, also bound north, in late May. More restless were these, constantly flitting and seeking food among the leaves, now in deciduous growth, again in the evergreens, ever moving on and ever singing their high-pitched, hissing whistle which is not so very different from the song of the black and white creeper, though a little more deliberate in movement and having a more staccato quality. So far as coloration goes one might mistake the male blackpoll for the black and white creeper were not the movements of the birds so distinctly different and the song as wiry but as soothingly crepitant as that of the cicada.
Night falls early in the deep heart of Chocorua, and full and clear the wood thrushes were yodeling of peace, one to another in the shadows, as I turned to descend. In the worn fields of the ancient clearing about the farmhouse where Bolles lived and loved the woods and all that therein lived with him, the song sparrows were trilling evening songs and the swifts twittering and circling nearer and nearer the big chimney which is their summer home. The bird cherry trees were white angels of bloom, and from all the land far and near the incense of opening blossoms made the air sweet and rose toward the high, mysterious altar of Chocorua’s peak as if in adoration of the rose glow of its sunset tints. Chocorua Lake was a mirror in which the glory of the summit, the blue dusk of the lower ranges and its own shores were reflected in perfect beauty. It was a sounding-board as well, across whose level came to the ear innumerable bird songs, singing carols of praise to the passing of day. Out of the blue depths of the sky the cool of night dropped like a blessing from heaven and seemed to soften and liquefy all melodies into purer, more mellow music. Wood thrushes and hermits sang in the shadows hymns of praise to the most high peak of the mountain, a pantheistic worship that was old ages before any spires other than those of the spruces had pointed the way to heaven.
Nightfall on Chocorua Lake
From the hillocks of the pasture to the topmost boughs of the forest all bird life joined in the worship, making the welkin ring with praise of the pure joy of life, a chorus that quivered into silence only with the passing of the rose of mystery from the very tip of the high horn of Chocorua. Nor did the silence last long. Before the last wood thrush had finished his “Good night; all’s well; God is good,” other songs of praise and the joy of life were echoing from swamp and wood and lake margin. Where the birds had ceased a myriad other voices took up new refrains. The dreamy trill of the tree frogs sounds from the perfumed dusk, a lullaby of the world primeval that sang the first man to sleep in some safe refuge in the deep woods. From the distant marsh the mingled voices of innumerable hylas ring a chorus of fairy sleighbells that rises and falls as the wind of evening drifts by. Nowhere in the world, I believe, can one hear such hyla choruses as he gets in May evenings from marshy pools among the New Hampshire hills. Coming from a distance the hypnotic insistence of the sound has a soothing, sleepy quality that lulls to rest. To seek its source and stand by the very border of the pool is to find it a frightful uproar that shrills in the ears and rings through the head till the deafened hearer is driven to the upland again.
On the lake margin in the failing light it came to me as a sleepy drone of tiny bells, as if goblin sleighing parties were coursing gayly in the night on the white May snow of petals beneath the bird cherry trees. It and the dreamy trilling of the tree frogs were but a background for the voices of night birds that sounded now that those of the day birds had passed. High in air floated the nasal “peent, peent,” of whirling nighthawks. Out of the velvet dusk across the glimmering water I heard a bittern working his old-fashioned pump, wheezily. “Cahugunkagunk, cahugunkagunk,” he burbled, the weirdest bird voice of any that comes from marsh or mountain, yet in the peacefulness of the place sounding neither lonely nor uncouth. I fancy him, too, with his long beak pointed to the heights, worshiping the mountain peak in his own tongue. Whip-poor-wills mourned gently one to another across the water as a token that the night had really come and the last glow faded from the lone summit now so immeasurably withdrawn into the sky among the stars.
A yellow-billed cuckoo called from the thicket, then, indignant at receiving no answer, sprung his rattle and waited. Roused out of his first slumber a white-throat gave a faint “tseep” of surprise, then trembled into music for a moment and went to sleep again. “Hap—pi—ness, hap-pi-ness, happiness,” he sang, the notes slipping away into infinite distance and blending with the perfect quiet of the night and the sky. It was the very spirit of the place speaking and reminding me again of the gentle writer who sang so clearly of the peace and beauty of the Chocorua woods and who now sleeps, after singing.
