That the sounds were wing-made I had no thought of questioning. I had seen the thing done,—seen it and heard it; and what shall a man trust, if not his own eyes and ears, especially when each confirms the other? Two days afterward, nevertheless, I began to doubt. I heard a grackle "sing" in the manner just described, wing-beats and all, while flying from one tree to another; and later still, in a country where boat-tailed grackles were an every-day sight near the heart of the village, I more than once saw them produce the sounds in question without any perceptible movement of the wings, and furthermore, their mandibles could be seen moving in time with the beats. So hard is it to be sure of a thing, even when you see it and hear it.
"Oh yes," some sharp-witted reader will say, "you saw the wings flapping,—beating time,—and so you imagined that the sounds were like wing-beats." But for once the sharp-witted reader is in the wrong. The resemblance is not imaginary. Mr. F.M. Chapman, in A List of Birds Observed at Gainesville, Florida,[8] says of the boat-tailed grackle (Quiscalus major): "A singular note of this species greatly resembles the flapping of wings, as of a coot tripping over the water; this sound was very familiar to me, but so excellent is the imitation that for a long time I attributed it to one of the numerous coots which abound in most places favored by Q. major."
If the sounds are not produced by the wings, the question returns, of course, why the wings are shaken just at the right instant. To that I must respond with the time-honored formula, "Not prepared." The reader may believe, if he will, that the bird is aware of the imitative quality of the notes, and amuses itself by heightening the delusion of the looker-on. My own more commonplace conjecture is that the sounds are produced by snappings and gratings of the big mandibles ("He is gritting his teeth," said a shrewd unornithological Yankee, whose opinion I had solicited), and that the wing movements may be nothing but involuntary accompaniments of this almost convulsive action of the beak. But perhaps the sounds are wing-made, after all.
On the day of which I am writing, at any rate, I was troubled by no misgivings. I had seen something new, and was only desirous to see more of it. Who does not love an original character? For at least half an hour the old mill was forgotten, while I chased the grackle about, as he flew hither and thither, sometimes with a loggerhead shrike in furious pursuit. Once I had gone a few rods into the palmetto scrub, partly to be nearer the bird, but still more to enjoy the shadow of a pine, and was standing under the tree, motionless, when a man came along the road in a gig. "Surveying?" he asked, reining in his horse. "No, sir; I am looking at a bird in the tree yonder." I wished him to go on, and thought it best to gratify his curiosity at once. He was silent a moment; then he said, "Looking at the old sugar house from there?" That was too preposterous, and I answered with more voice, and perhaps with a touch of impatience, "No, no; I am trying to see a bird in that pine-tree." He was silent again. Then he gathered up the reins. "I'm so deaf I can't hear you," he said, and drove on. "Good-by," I remarked, in a needless undertone; "you're a good man, I've no doubt, but deaf people should n't be inquisitive at long range."
The advice was sound enough, in itself considered; properly understood, it might be held to contain, or at least to suggest, one of the profoundest, and at the same time one of the most practical, truths of all devout philosophy; but the testiness of its tone was little to my credit. He was a good man,—and the village doctor,—and more than once afterward put me under obligation. One of his best appreciated favors was unintended and indirect. I was driving with him through the hammock, and we passed a bit of swamp. "There are some pretty flowers," he exclaimed; "I think I must get them." At the word he jumped out of the gig, bade me do the same, hitched his horse, a half-broken stallion, to a sapling, and plunged into the thicket. I strolled elsewhere; and by and by he came back, a bunch of common blue iris in one hand, and his shoes and stockings in the other. "They are very pretty," he explained (he spoke of the flowers), "and it is early for them." After that I had no doubt of his goodness, and in case of need would certainly have called him rather than his younger rival at the opposite end of the village.
When I tired of chasing the grackle, or the shrike had driven him away (I do not remember now how the matter ended), I started again toward the old sugar mill. Presently a lone cabin came into sight. The grass-grown road led straight to it, and stopped at the gate. Two women and a brood of children stood in the door, and in answer to my inquiry one of the women (the children had already scampered out of sight) invited me to enter the yard. "Go round the house," she said, "and you will find a road that runs right down to the mill."
The mill, as it stands, is not much to look at: some fragments of wall built of coquina stone, with two or three arched windows and an arched door, the whole surrounded by a modern plantation of orange-trees, now almost as much a ruin as the mill itself. But the mill was built more than a hundred years ago, and serves well enough the principal use of abandoned and decaying things,—to touch the imagination. For myself, I am bound to say, it was a precious two hours that I passed beside it, seated on a crumbling stone in the shade of a dying orange-tree.
Behind me a redbird was whistling (cardinal grosbeak, I have been accustomed to call him, but I like the Southern name better, in spite of its ambiguity), now in eager, rapid tones, now slowly and with a dying fall. Now his voice fell almost to a whisper, now it rang out again; but always it was sweet and golden, and always the bird was out of sight in the shrubbery. The orange-trees were in bloom; the air was full of their fragrance, full also of the murmur of bees. All at once a deeper note struck in, and I turned to look. A humming-bird was hovering amid the white blossoms and glossy leaves. I saw his flaming throat, and the next instant he was gone, like a flash of light,—the first hummer of the year. I was far from home, and expectant of new things. That, I dare say, was the reason why I took the sound at first for the boom of a bumble-bee; some strange Floridian bee, with a deeper and more melodious bass than any Northern insect is master of.
It is good to be here, I say to myself, and we need no tabernacle. All things are in harmony. A crow in the distance says caw, caw in a meditative voice, as if he, too, were thinking of days past; and not even the scream of a hen-hawk, off in the pine-woods, breaks the spell that is upon us. A quail whistles,—a true Yankee Bob White, to judge him by his voice,—and the white-eyed chewink (he is not a Yankee) whistles and sings by turns. The bluebird's warble and the pine warbler's trill could never be disturbing to the quietest mood. Only one voice seems out of tune: the white-eyed vireo, even to-day, cannot forget his saucy accent. But he soon falls silent. Perhaps, after all, he feels himself an intruder.
The morning is cloudless and warm, till suddenly, as if a door had been opened eastward, the sea breeze strikes me. Henceforth the temperature is perfect as I sit in the shadow. I think neither of heat nor of cold. I catch a glimpse of a beautiful leaf-green lizard on the gray trunk of an orange-tree, but it is gone (I wonder where) almost before I can say I saw it. Presently a brown one, with light-colored stripes and a bluish tail, is seen traveling over the crumbling wall, running into crannies and out again. Now it stops to look at me with its jewel of an eye. And there, on the rustic arbor, is a third one, matching the unpainted wood in hue. Its throat is white, but when it is inflated, as happens every few seconds, it turns to the loveliest rose color. This inflated membrane should be a vocal sac, I think, but I hear no sound. Perhaps the chameleon's voice is too fine for dull human sense.
