Continuing my journal, I will now give extracts which illustrate, principally, the return home of the rooks at night and their flying forth in the morning—those two aspects of their daily winter life which are the most full, perhaps, both of interest and of poetry.
"December 9th.—This afternoon at about 3.30 I find vast numbers of rooks gathered together on a wide sweep of land, close to their roosting-place.
"Even now—and they are being constantly reinforced—they must amount to very many thousands, and cover several acres, in some parts standing thickly together, in others being more spread out. There is an extraordinary babble of sound, a chattering note and the flexible, croodling one being conspicuous. Combats are frequent—any two birds seem ready to enter into one at any moment—and they commence either, apparently, by sudden mutual desire, or else by one bird fixing a quarrel on another, which he does by walking aggressively up to him and daring him, so to speak. In fighting they stand front to front, and then spring up at each other—like pheasants, but grappling and pecking in the air as do blackbirds and small birds generally. Sometimes one bird will be worsted in the tussle, and you instantly see it on its back, striking up with claws and beak at the other, who now bestrides it. It is easier to see this result than to be sure as to the process by which it is arrived at—whether, for instance, the overmatched bird falls, willy-nilly, on its back, or purposely throws itself into that position, so as to strike up like a hawk or owl. I think that this last may sometimes be the case, from the very accustomed way in which rooks fight under such circumstances; but, no doubt, it would only be done as a last resource. The rooks, however, do not seem vindictive, and their quarrels, though spirited, are usually soon over. They may end either by the weaker or the less acharné bird retiring, in which case the pursuit is not very sustained or vigorous, or else by both birds, after a short and not very rancorous bout, pausing, appearing to wonder what they could have been thinking about, and so walking away with mutual indifference, real or assumed. Often one bird will decline the combat, and in this case, as far as I can see, it is not molested by the challenger, however bullying and aggressive this one's manner may have been. A rook coming up to another with the curious sideway swing of the body and a general manner which seems to indicate that he thinks himself the stronger of the two, looks a true bully.
"One rook has just found something, and, whilst standing with it in his bill, another comes forward to dispute it with him, but the attack is half-hearted, and seems more like a mere matter of form. Afterwards, when the same bird has the morsel on the ground in good pick-axeing position, a second rook advances upon him with a quick, sideway hop, looking cunning, sardonic, diabolic, and much for which words seem totally wanting. But this attack, though swift and vigorous, is not more successful than the former one. The lucky rook gets off with his booty, and has soon swallowed it. Amongst rooks, the finding of anything by any one of them is a recognised cause of attack by any other. This is taken as a matter of course by the bird attacked, and if he holds (and swallows) his own, which, as he has a clear advantage, he generally does, no resentment is manifested by him—there is not even a slight coolness after the incident is over. If, however, the attack should be successful, then it is very different. The annoyance is too great for the robbed bird, and he becomes very warm indeed. He makes persistent violent rushes after the robber, is most pertinacious, and clearly shows that kind of exasperation which would be felt by a man under similar circumstances. It seems not so much his own loss, as the success and triumphant bearing of the other bird, that upsets him. He has failed where he ought to have been successful, and of this he seems conscious.
"When one rook makes his spring into the air at another, this one will sometimes duck down instead of also springing. The springer, then, like 'vaulting ambition,' 'o'erleaps himself and falls on the other side.' I have just seen this. The rook that bobbed seemed to have scored a point, and to know it, which the other one confessed shamefacedly—no, indescribably, a rook cannot look shamefaced. The advantage was not followed up by the successful bird, but the combat ceased, I think, in consequence.
"I now notice a hare a little on the outside of the phalanx of rooks, at the part of it nearest to myself. All at once he makes a little run towards them as if charging them, and sits down, making one of their first line, and almost, as it seems, touching two or three. After sitting here for some while the hare makes another little run, this time right in amongst the rooks, several of which he puts up as though on purpose—each of the birds giving a little jump into the air with raised wings, and coming down again. He then sits down as before, but this time all amongst them. This he repeats several times, making little erratic gallops through the black crowd, in curves to one side and another, and appearing to enjoy the fun of causing rook after rook to jump up from the ground. Half-a-dozen times he runs right at a rook that he might easily have avoided, and sits down amongst them two or three times, again. At last, in a final gallop, he pierces the squadron and continues on, over the land. This certainly appeared to me to show a sense of fun, if not of humour, on the hare's part, and as—with a few noted exceptions—it is the rarest thing to see one species of animal take any notice of another, I was proportionately interested.
"It is now half-past four, and for about an hour the great assemblage has been increased by a perpetual stream of rooks, that sail up and descend into it with joyous wheels and sweeps. For some time, too, flocks of the birds have been flying from the ground into trees near. They fly by relays, and from the farthest part of the troop—that is to say, from that part which is farthest distant from the woods where they are to roost. First one band of birds and then another rises from the outer extremity, flies over the rest, ascending gradually, and wings its way to the trees. By these successive flights the assemblage is a good deal shrunk, and does not cover nearly so much ground, when the remainder—still an enormous number—rise like a black snowdrift whirled by the wind into the air, and circle in a dark cloud, now hardly visible in the darkening sky, above the roosting-trees, with a wonderful babel of cries and noise of wings.
"At 4.40 this deep musical sound of innumerable crying, cawing, clamouring throats is still continuing, and once, I think, the birds rise from the trees into which they have sunk, and circle round them again. Now they are in the trees once more, but the lovely cawing murmur—the hum, as though rooks were rooky bees—still goes on.
"4.47.—It is sinking now. Much more subdued and slumberous, deliciously soothing, a rook lullaby.
"December 11th.—A stern winter's day, the earth lightly snow-covered, but bright and fine in the morning. At 3 p.m. I am where the rooks roost, a plantation of fir-trees—larches—dark, gloomy and sombre, with a path, piercing them like a shaft of light, over-arched with their boughs, silvered now with light snow-wreaths. Just in this gloomy patch they sleep, but with a light belt of smaller firs opposite, or with adjoining woods of oak and beech they will have nothing to do, leaving these latter to the woodpigeons.
_p279.jpg)
"They are gathering, now, from all parts, filling the trees round about the ploughed land—now all white—flying in flocks about them, then descending into them again.
"Still coming and coming out of the sunset, specks growing into birds. The stern, snow-covered landscape, the red glow of the sunset, and the black, labouring pinions against it make a fine winter scene.
"4.37.—Back at the larches, and only just in time to stand concealed within them, before the rooks are there. All seem coming, a black, flying multitude. They have reached the larches and fly about over them in wide, sedate circles, coming in relays, as last night. Joyous voices—innumerable multitudes—a torrent of wings! All in a broad, rapid, streaming flight to the larches. They sweep, dash, circle and eddy over them, black flashes in the deepening gloom. They sweep into them, and the snow, swept by their wings, falls in a drizzle from the branches. Joyous, excited cries, 'chu, chu, chac, chac' The whole dark grove is a cry, a music. Still other bands, they burden the air. Band after band—now with a pause between each. They fly swiftly and steadily up, at a not much greater height than the trees, not descending into them out of the sky.
"A longer pause, followed by another hurrying band. And now the moon is shining through the larches, and the black, ceaseless pinions go hurrying across its face. Groans, moans, shrieks almost, yells amongst the larches, all mingled and blending—but sinking now. A marvellous medley, a wonderful hoarse harmony! Here are shoutings of triumph, chatterings of joy, deep trills of contentment, hoarse yells of derision, deep guttural indignations, moanings, groanings, tauntings, remonstrances, clicks, squeaks, sobs, cachinnations, and the whole a most musical murmur. Loud, but a murmur, a wild, noisy, clamorous murmur; but sinking now, softening—a lullaby.
'I never heard
So musical a discord, such sweet thunder.'"
When the rooks sweep down, thus, into their roosting-trees they frequently do so with a peculiar whirring or whizzing noise of the wings, but although this sound is in perfect consonance with the motion which it accompanies—insomuch that one has to use the same words to describe each—yet it does not seem to be produced by it. At least, it bears no relation to the height from which the birds swoop, nor—as would seem to follow from this—with the impetus of the descent. It may be a matter of impetus, but to me it has often seemed more as though the sound gave the idea of impetus, or added to it, and that the sweeps were, sometimes, just as impetuous, or even more so, when made without it. As I observed, the birds flew to their trees at a very moderate height—not very much, indeed, above the trees themselves—and, whilst many made the whizzing sound, the great majority swooped down without it. It seems, therefore, to be a special sound produced by the rooks at pleasure, and always accompanying an excited frame of mind. First one bird and then another gets excited, and dashes suddenly down with the whirring or whizzing noise, so that, as the sound is not vocal, and is only heard upon such occasions, it has all the appearance of being caused by the quick, sudden motions of the wings. But it is possible that some particular way of holding the quill-feathers of the wing or even tail is required to produce it, in combination with the general movements, and this would account for its being sometimes heard and sometimes not heard, when these latter are identical.[1] The curious burring note is likewise, but far less frequently, an accompaniment of these wild excited sweepings, and this is most often the case when they are from a considerable height. Here, again, the note bears a clear relation to the bird's mental state, so that it would appear that the degrees of pleasurable excitement cannot be estimated by the motions alone. The "burr," in my opinion, when well and loudly uttered—for here, again, there is much variety—marks the maximum of a rook's content, at any rate in a certain direction.
"December 15th.—At 7 a.m. I am at the point of the road nearest to the rookery, and I hear the sweet jangle, 'the musical confusion,' already beginning. Not much, however—subdued and occasional—influenced, perhaps, by the heavy morning mist that hangs over trees and earth. After a time I walk to an oak just outside the plantation, and sit listening to the rising hubbub—now rising, now falling. A sad, mist-hung morning, the earth lightly snow-decked; raw and chill, but not so frostily, bitingly cold as yesterday and before. The general intonation of the rook voice is pleasing and musical—how much more so than the roar of an at-home as the door is flung open, even though one has not to go through that door! There is very great modulation and flexibility—more expression, more of a real voice than other birds. One feels that beings producing such sounds must be intelligent and have amiable qualities. One of the prettiest babbles in nature!
"One catches 'qnook, qnook,' 'chuggerrer,' 'choooo-oo.' At intervals the single, sudden squawk, or continued trumpeting, of a pheasant, breaks abruptly into the sea of sound, then mingles with it. Every now and again, too, there is a sudden increase of sound, which again sinks.
"At 7.50 the rooks are still in bed, but a pheasant—a fine cavalier—comes running towards me over the snow. He makes a long and very fast run for some fifty yards or so, then stops and draws himself bolt upright, seeming to stand on tip-toe. More than upright he is—bent back, trying to look like a soldier, but obliged to be graceful and elegant. Standing thus, he seems on the very point of trumpeting, yet does not, and then runs on again. He repeats this, several times, each time thinking of trumpeting, but desisting and going on.
"At 7.58 the flight out commences. Two or three birds are a little in front, none very prominently so, and others are catching them up and seem just on the point of passing them when they are lost to me in the mist. There is nothing suggesting a leader. If they were led it was not by one of themselves, for with them and in their very fore-front two little birds were flying, who passed with them out of sight. They were tits, I think, and in another flight out, after one of the pauses—for the rooks fly out by relays, like the starlings—I noticed one other, all three, I believe, being parus cæruleus. There are quite a number of tits in the plantation and woods adjoining, but why just three should leave it and go flying with the rooks through the mist, over the open country, if not for the mere joy and fun of the thing, I know not. All at once a number of the out-flying birds turn in their flight, and swoop back, with a great rush of wings, to the plantation. Afterwards, at intervals, there are other such returns, little bands of the birds seeming to say, 'Oh, let's go back to bed. It's much nicer,' and doing so. This, too, is exactly what the starlings do. The birds, as they fly, are all vociferous, and the air is laden with a pleasant burden of 'chug-chow, chug-chow, chug-chow. Chugger-chugger-chow. How-chow, how-chow.' The rooks talk a kind of Chinese.
"At 8.20 the principal flight is over, but still there is a stream of birds issuing out, and most of these are now going down on to the land. All at once, these—that is to say, all the rooks on the ground—rise and fly to the trees, the birds who have been sitting in them join them in the air, they all fly about together over the trees, and then go off in two or more bodies, and in different directions. There has been no sign of a leader, or of leadership, in any of the flights out, or in any of the birds' actions.
"At 8.45, when no more rooks are to be seen, either flying or on the ground, I walk through the larches, and put up a good many birds who have remained sitting in them, instead of going out with the rest. I, then, walk all round the plantation, and find numbers of rooks sitting in the beech-trees that edge it on one side. Though the numbers seem small, after watching the innumerable flights out, they may yet amount to some hundreds. Thus, some small bodies of birds, and even some individuals, have not been influenced by the action of the vast majority, but have sat still whilst the rest flew forth—unless, indeed, all of them have first flown out, and then back again; but this I do not think is the case. Two great leading principles seem to govern all the actions of rooks—independence and interdependence. All are influenced by all, yet all can, on any and every occasion, withstand that influence, and think and act for themselves.
"Sometimes the sweepsback of the birds into the trees are very curious, seeming to indicate some unknown force at work. There is a sort of commotion—a turmoil of some sort—causing a cessation of the regular, orderly flight, the voice varies, there is a rush of wings, and out of this trouble, as it were, the backward swoop is born. Then the wavering stream—or rather a certain wavering eddy in it—flies on, and again the voice becomes the musical 'har-char, har-char' (a better rendering than 'how-chow'), which characterises the flight out.
"It is as though a sudden surge of thought said 'Back!' and swept some back, but a deeper, stronger surge said 'On!' and on the greater number streamed.
"Again, the stream of flight will sometimes be interrupted by a sort of sweeping or drifting together of a number of the birds, making an eddy in it, as it were—an interruption and perturbation in the current, difficult to describe, and over before one can fix the proper words to it; but indicating some sort of emotion in the birds, a rush of feeling of some kind, something tiresome to note, but which ought to be noted. Once, too, I have seen a single rook flying straight back against the general current of the stream, meeting and passing all the rest on his way to the trees, seeming the very emblem of a fixed intent.
"These curious, pausing, and hesitating movements, in which an idea that seems at first vague becomes, all at once, definite, seem to me to have their origin in what may be termed collective thinking—for this gives a better idea of the appearance of the thing than does the term thought-transference, though that may more correctly indicate the process. The birds do not appear to be influenced by the actions—the external signs of thought—of each other, but numbers of them seem similarly influenced at or about the same moment of time. In fact, they often act as though an actual wind had swept them in this or that direction—when this cannot have been the case, I hasten to add.
"February 10th.—A hard black frost, bitterly, bitingly cold. At 5.30 a.m. I steal into the dark plantation, and silently take my place at the foot of one of the tall, sighing trees. Softly as I try to move, I disturb some of the sleeping birds, who make heavy plunges amongst the trees, or beat about, for a little, through 'the palpable obscure' above them. But, leaning against the trunk, I am now rock-still, and soon they settle down again, though 'talking'—some nervous inquiry—continues a little, breaking out first here and then there, around where I sit. I soon notice, however, that these outbursts have no relation to my whereabouts, but take place over the whole plantation, and I come to the conclusion that they have nothing to do with the late disturbance, which is now, evidently, forgotten. The night, in fact, is passing, and the rooks are beginning to be rooks. Such noises in the utter darkness, amidst the shroud-black firs, sound ghostly, and may, perhaps, have given rise to the idea of the night-raven. In the winter, it must be remembered, it is night, practically, for some time after the peasantry of any country are up and about; nor can I conceive of any sounds more calculated to give rise to superstitious ideas than some of those I hear about me. In the real night, too, a belated peasant might easily get a note or two from some awakening rook, and, both by virtue of time and place, and the actual quality of the sound—as I can testify—it would sound very different to what he was accustomed to in the daytime. It is probable that, in a country where ravens were known, and inspired those superstitious feelings which they always have inspired, such sounds, issuing out of the darkness, would be ascribed to them, rather than to the homely rook; and here we should have the night-raven—a bird 'frequently met with in fiction, but, apparently, nowhere else.' Possibly, however, the raven itself may sometimes utter its boding croak through the darkness, and ravens have been, and, in some parts, still are, numerous.
"Gradually the plantation becomes quite a wonderful study of sounds, there being an extraordinary variety, and some of them most remarkable. One, that seems deep down in the throat, suggests castanets being played there, but castanets of a very liquid kind, water-castanets, if such there could be, but, if not, it gives the idea. This curious sound is only uttered occasionally by some particular rook, and it recalls—perhaps is—the well-known burring note that I have heard under such different circumstances. If so, it can only be as a recollection that the bird utters it. I have not the space to reason this, but, assuming it to be so, may we not see, here, one of the alleys leading up to language? A certain sound is uttered during the doing of a certain thing. It becomes associated in the mind with that thing, with the doing of it, and with the state of mind under the influence of which it is done. At first, perhaps, unconsciously, then consciously, it is uttered when such action is recalled, and the utterance recalls it, also, to the mind of whoever hears. Here, then, is a certain well-understood sound conveying a certain idea or ideas—as, first, 'burr,' a particular kind of joyous flight: then, 'burr,' something as joyous as such flight, and so, joy: and lastly, 'burr,' the actual joyous flying, the root, therefore, of the verb 'burr,' to fly joyously, and, so, to fly. Darwin supposes language to owe its origin 'to the imitation and modification of various natural sounds, the voices of other animals and man's own instinctive cries, aided by signs and gestures.' To repeat a certain sound, that had been at first the mere mechanical adjunct of a certain act or state, when one recalled that act or state, would be, as it seems to me, an extremely early—perhaps the earliest—step, passing imperceptibly from feeling into thought, and leading on to imitation. Such speculations may be permitted one, in a dark fir-plantation, surrounded by rooks and waiting for the morning.
"One thing, however, I record as a fact, which appears to me somewhat curious. Though the plantation is continuous, without any break other than the narrow path that runs through its centre, and though it is simply crowded with rooks, every tree holding a great many, yet I notice that an outbreak of sound in any particular part of it does not spread over the whole, as one might have supposed that it would, but dies gradually out, as it radiates from the point where it arose. Thus, there are zones of sound, isolated from each other by intervening areas of silence. Just at this moment, after I have sat, for some time, silent, and all alarm has subsided, there is a great clamorous outburst some little way off! It must have some special cause which I cannot divine, but this commotion does not, any more than the lesser ones, spread itself through the packed community, but is strictly isolated. How strange this seems! A parliament (though I heard no nonsense talked) of lively, eminently gregarious birds, all of which are noisy at one time or another, and from the thick of them a storm of clamour bursts: would not one think that the birds sitting cheek by jowl with the stormers would storm too, and so 'pass it on'? Why should there be a periphery, and what should limit the chorus except the bound of the plantation itself? Do crowds shout in patches? That the clamour should cease, after a time, is, of course, natural, but why, though it died along the road by which it travelled, should it not keep travelling on, through all the black, serried ranks? If rooks were influenced only by the outward manifestations of each other's emotions, one might, surely, expect this. But now, if they were influenced more by the thought itself, rapidly transmitted from one to another of them, then, whenever this factor ceased, for whatever reason, to act, the birds beyond the limits of its action might be unaffected by the cries of those who had felt its influence, for they would have been accustomed to look for a sign from within, and not from without. They might then hear, on some occasions, without being impelled, though on other occasions they might choose, to join. It may be difficult to realise such a psychical state, but that does not, of itself, make the state impossible. Its possibility would depend upon the reality or not of collective thinking, or thought-transference, and observation is (or should be) our only means of deciding as to this.
"As light struggles out of the darkness, the silence is broken more and more frequently, at some point or other of the plantation, so that the sound is disseminated over a larger and larger space, till, for some little while before the flight, the whole rookery seems to be talking at one and the same time. In reality, however, there is a constant cessation and renewal on the part of each individual bird.
"At 6.30 the sounds take a deeper and more emphatic tone. There is more solemnity, more meaning, and the meaning grows plainer and plainer as the asseveration becomes more and more emphatic, that 'it is, yes is, is really, positively is, is, is, is, is the morning.'
"At 6.35 there is the light, joyous 'chug-a, chug-a, chug-a,' besides which one catches—if one has a good ear—'hook, chook,—hook, took—hook-a-hoo-loo—chuck, chuck, chuck, chuck, chuck, chuck,—polyglot, polyglot.'
"Then there is a question—a serious and solemnly propounded question—'Quow-yow?' The answer—from another rook—is immediate and undoubted—'Yow-quow.'
"There are sounds which just miss being articulate and just evade one's efforts to write them down. It is significant that I have to use the word 'talking' to describe the rook's utterances. It is the one word; another would sound forced and strained.
"Throughout the babel, there is a tendency for it to sink and rise in sudden accentuations and diminishments. Now there is a diminishment, and a bird in the tree next to mine gives a sleepy stretch out of one wing, which has all the appearance of a yawn. But I see no other bird yawning, nor do I notice any toilette, any preening of the feathers.
"Now, at close on 7, the flight out is preceded by a flight of the birds inside the plantation, from one tree to another, and this, passes, gradually, into the full forth-streaming. Just above the trees, now, they pass in endless flakes of a black and living snowstorm. Their flight is swift, hurrying, joyous. They flap, but there are, often, long sweeps on outspread wings, between the flaps. And ever, as they fly, they greet the cold, stern morning with their joy-song of 'chowhow, a-chuck, a-chuck, a-chuck, a-chuck, a-chuck-a.'
"Nearly a month later, a smaller, but still numerous, body of the birds had chosen a new roosting-place—a clump of Scotch firs on a lonely heath, which had stood vacant all the winter, a point interesting in itself, but which—for the old reason—I am unable to discuss.
"March 4th.—I got to the plantation towards the end of the afternoon, and resolved to wait there, in order to see wood-pigeons fly into it in the evening. Not many came, but at six o'clock I saw what I thought was a large band of them fly into an oak-tree which I had noticed just outside the plantation, where they remained for a minute or two. They then flew on to the plantation, sweeping over it once or twice before settling, and I saw that they were rooks. As will be seen from this, they had hitherto been silent. When they had settled in the trees there was some talking, but strangely little, I thought, for rooks, and very soon afterwards there was hardly a sound. They remained thus, for some little time. All at once, with extraordinary suddenness, with a sound of wings so compact and instantaneous that it was almost like the report of a gun, the whole troop burst suddenly out of the trees, which were on the outer edge of the plantation, flew a little way over the heath (I caught them against the fading red of the sky), wheeled round, returned, and shot into them again. There was a little cawing as they got back, but this soon sank, and again there was silence. Then, in a moment, there was the same sudden rush of wings, and the whole black cloud shot, like one bird, into the open sky, wheeled again, and shot back, as before. This occurred nine times in succession, at intervals of not longer, I should think, than three or four minutes. In the later rushes the birds circled several times—flying out again, each time, over the moor—before resettling in the trees. After the last time they settled in a different part of the plantation. Immediately before two of the rushes out, I heard a loud 'caw,' in rather a high-pitched tone, from a single rook, which seemed to be the signal for the exodus, whilst, almost immediately afterwards, there was another single note of quite a different character—deeper and more guttural—from either the same or another bird still in the trees, which seemed to call the rest back again. A well understood signal-note indeed, would be the easiest way of accounting for these sudden and extraordinarily simultaneous flights and returns, but it was only twice out of the nine times, that this explanation seemed tenable. On other occasions, the caw, at starting, seemed only one of many, or did not correspond so exactly, in point of time, with the sudden flight out, as the theory seemed to require, whilst the deep 'quaw,' which seemed to be made by one particular rook, who always stayed behind, and which I had at first thought called the others back, would be heard directly after they had flown, as well as after they had returned. Several times, too, the black cloud and thunder-storm of wings seemed to burst out of silence itself. I came to the conclusion that a signal-note was not the explanation. All I can say is, that—from what cause or actuated by what impulse, I know not—some fifty to a hundred rooks shot, as though they shared one soul, nine times in succession, from those dark pines, circled a little over the dusky moor, and then shot back into them again. No one, except myself, was near. It was one of those very lonely places where, at almost any time, one can count upon seeing no one, and, altogether, it struck me as an extraordinary phenomenon.
"Once more, the old Greek idea of the φημη—a sudden thought, sweeping through a crowd as a wind sweeps through a grove of trees—seemed to me to be the only view which met the facts. But what, then, is the φημη, and whence, or why, the impulse?
"All this time, I should say, though quite near, I was perfectly concealed, standing against a tall pinetree, around the trunk of which I had helped to make a wigwam—already partly formed—of some of its own fallen and bending branches. This, with the gloom of the plantation itself, and the falling night, was a perfect concealment, even at a foot's pace, as will shortly appear.
"It was just after the last return of the out-shooting birds that, looking up, I saw what I at first supposed was they, but soon found to be another, and a very much more numerous, band of rooks, who, as they came up, were joined by the other ones, in the air. Now, for the first time—for the cloud came up in silence, and, since the last flight out, there had been silence in the plantation too—there was a tremendous clamour of voices, filling the whole place, and then a black, whirling snowstorm of rooks began to shoot, whirr and whizz about, over, into, through, and amongst the fir-trees, in a most extraordinary manner. The rapidity with which they shot about, their hurtlings, their sideway-rushing sweeps and swoops, their quick, smooth turns and gliding zig-zags, avoiding, by miracle, each other and the trunks of trees, was most extraordinary, whilst the whishing noise of their wings through the air was almost frightening. The plantation seemed to be a huge disturbed bee-hive, with great black bees dashing angrily about it. It was a snowstorm with the flakes gone mad; but black, a black, living bird-storm, and it produced in me a feeling of excitement, a peculiar, almost a new, sensation, analogous, perhaps, to what the birds themselves were feeling. What struck me and made it more interesting, was that it was a special exhibition, a 'set thing,' something indulged in by the birds with a peculiar pleasure in the indulgence, something appertaining to the home-coming—the 'heimkehr'—emanating from and requiring a particular, psychical state. This is by far the finest display of the kind I have yet seen, and I was in the very midst of it. Considering the number of birds—there must, I think, have been several hundreds—the speed at which they dashed about and the smallness of the space in which so many were moving with such violence, and so erratically, it seems wonderful that they never came into collision, either with one another or the trunks or branches of the fir-trees. In the plantation, when I came into it, two dead rooks were lying, and I had also picked up a dead one in the larger roostingplace. The keeper said it had been 'turned out,' which was vague, and then, more definitely, that rooks sometimes died of old age. It seems not impossible, or even improbable, that in these violent whizzings of a great number of rooks together, amongst closely growing trees, and in the gloom of evening fading slowly into night, accidents may, sometimes, occur. The rooks, I should say, in their violent whizzing darts and dashes, shot down, sometimes, to about half the height of the trees, and were, in general, right in amongst them. This wonderful scene of bird excitement, lasted, I should think, about ten minutes, in full action, but grew fainter as the trees became more and more packed with birds, till, at length, all were settled. Every tree held several. On two slender ones—not pines but birches—just in front of me, and but a step or two off, there must have been more than twenty. The noise and clamour, during the whole time, was tremendous."
It is not always that rooks dash thus madly to rest. Here—on the very next evening and at the same place—is another type of the home-coming.
"March 5th.—A little after 5.30, a hooded crow flies into the clump of pines. Whether it stays there for the night, with the rooks, I cannot tell, but it does not seem to me improbable. I have seen single birds of the former species flying amidst large bands of the latter, and they are constantly together in the fields, where they behave, in regard to each other, very much as though they were of the same species.
"At 6.10, which is later than the first batch of rooks came yesterday, five birds fly over the plantation but do not go down into it.
"At 6.15 a large, united flock of, perhaps, six or seven hundred fly up from over the ploughed land skirting the moor. They utter the 'chug-a, chug-a' note, characteristic of the homeward flight, but quietly; there is very little noise. Just before reaching the plantation they make a sort of circling eddy in the air—becoming, as it were, two streams that drift through each other—then sail on together and circle some three or four times exactly over it, before descending into its midst. This they do without any of the excited sweeping about of yesterday, and though, of course, the voice of so many birds is considerable, yet, comparatively, it is very subdued, and in a very short time—about five minutes—they all seem settled. Before long, however, some of them, but quite an inconsiderable number, rise and fly about over the trees again, but soon resettle, and there is, now, a deepening silence. No one could imagine that that little lonely clump of trees held all that great army of birds. All, to-night, has been wonderfully decorous. There was something majestic in the way the rooks flew up—slow-seeming yet swiftly-moving. Their flight round, over the trees, before sinking, like night and with the night, upon them, was a fine sombre scene—the thickening light ('light thickens and the crow'), the silent, lonely-spreading moor, the gloomy trees, and, above them, slow-circling in the dusky air, that inky cloud of life. It was gloomy, the effect—saddening, yet with the joy of nature's sadness. The spirit of Macbeth was in it—'Here on this blasted heath'—
'Good things of day begin to droop and drowse,
Whilst night's black agents to their prey do rouse.'
"But they sank peacefully down, and all of evil seemed to go, with their sweet, joyous, innocent, and well-loved voices."
Here is one last picture, and I would point out that, on all these three occasions, when the rooks slept in changed quarters, at a later time of the year, the way in which they approached or entered the trees, and the height at which they flew, varied, in a greater or less degree, from what it had been before.
"March 11th.—At 6.20 a small band of rooks comes flapping along in the usual jog-trot way, and enters the plantation. Some five minutes afterwards a very large number sail up, flying at a great height, and gather like a storm-cloud above it. They hang over it, then drift, circling, a little, descending gradually on outspread wings, till, when at a moderate height above the tree-tops, they begin to shoot down into them in the rapid, whizzing manner before described. But they do not all do this at the same time. It is a slow and gradual—in its first stages almost a solemn—entry, and the shooting down itself becomes, gradually, less rapid. How grand is this to witness! It is a living storm-cloud discharging its black winged rain—a simile, indeed, which can hardly fail to suggest itself, so apparent is the resemblance. At a distance, I think, the two might be really confounded. The gradual sinking of the birds, by fine gradations and almost imperceptibly, from their vast height, is more like an atmospheric than an organic phenomenon. The effect is heightened by the loneliness and utter silence, by the deepening shadows. Night sinks as they sink, but the moon is now becoming luminous, and the swish and 'coo-ee, hook-a-coo-ee' of peewits is about one on one's way back, over the heath."
I will conclude this fragment of my rook diary by giving a list of some of the distinct notes or sounds which I have, at different times, heard the birds utter. It is but a small page out of their vocabulary, but it may, perhaps, serve to draw attention to the great powers of modulation and inflexion which these birds possess. I must confess that the way in which the voice of the rook is usually spoken of makes me wonder. To me it has often seemed as though these birds were really in process of evolving a language. In only a few cases, however, have I been able—or have I thought myself able—to connect a note with any particular act or state of mind. Here is the list:
Caw (the ordinary "caw" more or less).
Chĭ-choo, chĭ-choo, chĭ-choo.
Cha.
Chug-a, chug-a, chug-a.
Chug-chaw.
Chack-a, chack-a.
Choo (very prolonged).
Chuck (loud, clear, and distinct).
Chee-ow (very lengthened).
Hă-chă ("a" as in "hat").
Har-char.
How-chow, or chow-how.
Hoo, hoo.
Hook-a-hoo.
Hook-a-hoo-loo.
Kwubba-wubba.
Ow (prolonged, a peculiar musical piping note).
Polyglot (or something remarkably like it).
Quar-r-r-r.
Quor-r-r-r-r-r (very prolonged, and deep, as in remonstrance).
Quow-yow, or yow-quow.
Shook, shook, shook (soft and quickly repeated. Have heard it uttered by rooks when flying home belated, after the great majority had settled in the roosting-trees).
Tchar.
Tchar-r-r (with a little roll in it).
Tchu or tew.
Tchoo-oo (very deep and guttural).
The peculiar "burring" note (uttered, but by no means always, when the birds swoop down on to trees, especially the roosting-trees. It is not heard very frequently).
A peculiar sound like a kind of bleat, with a very complaining tone in it.
A short, sharp, single note, much higher than the ordinary caw.
A kind of grating scream, much higher than the usual tone.
A hoarse "mew," or "miaul" almost, as though a rook were trying to imitate a cat, or a cat a rook.
The liquid castanet-note in the throat, suggesting the "burr," but not quite it.
Various other curious little sounds in the throat, some of them clicks.
- ↑ With regard to the above, however, I am now no longer so sure. Je me'en doute. When the rooks descend from a height, the sound made is often most remarkable, being that of a mighty rushing wind filling the air.
