But, though I missed the feeding, I twice saw the raven mother—the real one—cling on to the side of the nest and look in upon her young ones, who rose and greeted her hungrily. That was a glorious thing to see. There was something in the bird's look almost indescribable, a blending—as it seemed to me—of cunning, criminal knowledge combined with lightheartedness, and strong maternal affection. With the first two of these, and with the stately, yet half grotesque action, the bright, black eyes, and steely, glossy-purpling plumage (it never looked black through the glasses), a faint, flitting idea, as of the devil, was communicated, enhancing and giving piquancy to the delight. She hung thus for some moments, seeming to enjoy the sight of her children, yet all the while having her black, cunning eyes half turned up towards myself. Then she flew away, joining her mate, who had waited for her some way off at the accustomed place on the cliffs. It was when I saw her like this, and when the glasses isolated her from the general of rock and sea, that this raven seemed to assume her true size and dignity, and to become really a raven. When she flew it was different. Her sable pinions beating against the face of the precipice added no effect to it, but she was instantly dwarfed and dwindled, and became as nothing, a mere insignificant black speck, against its huge frowning grandeur.
Though, really, their plumage is all of gleaming, purply blues, at a little distance, and when they fly, ravens look a dead ugly black, which is also the case with rooks, who are almost equally handsome when seen closely. Their flight is peculiar, and though it strikes the imagination, yet it cannot be called at all grand or majestic in the ordinary sense of those words. The wings, which are broad, short, and rounded—or at any rate present that appearance to the eye—move with regular, quick little beats, or, when not flapped, are held out very straightly and rigidly. When thus extended, they are on a level with or, perhaps, a little below the line of the back, and from this, in beating, they only deviate downwards, and do not rise above it, or very triflingly so, giving them a very flat appearance. A curious curve is to be remarked in the anterior part of the spread wing, at first backwards towards the tail, and then again forwards towards the head. All the primary quills seem to partake of this shape, and they are also very noticeably disjoined one from another, so that the interspace, even whilst the wing is beaten, looks almost as wide as the quill—by which I mean the whole feather—itself. I tried to imagine the effect of a number of these sombre, quickly-beating pinions with the short eager croak, having something of a bellowing tone in it ("the croaking raven doth bellow for revenge") over the wide-extended carnage of an ancient battlefield, and I thought I could do it pretty well—in spite of the difficulty, in the present day, of conjuring up such scenes.
Raven: The Game of Reversi.
But, though the ordinary flight of ravens be as I have described, it does not at all follow that they may not sometimes soar or sail for long distances through the air, or descend through it at great speed, and with all sorts of whirring and whizzing evolutions. For all these things do the rooks, and yet their ordinary flight is of a heavy and plodding character. One very peculiar antic, or "trick i' the air," the raven certainly has. Whilst flapping steadily along with regular, though quick beat of the wings, it closes these all at once, quite tightly, as though it were on the ground, and immediately rolls over to one side or the other. Either the roll is complete, so that the bird comes right round again into its former position, or else, having got only so far as to be back downwards, it rolls back the reverse way. This has a most extraordinary appearance. The bird is stretched horizontally in the position in which it has just been flying, and in rolling over makes one think of a barrel or a man rolling on the ground. Being in the air, however, it may, by dropping a little as it rolls, make less, or, possibly, no progress in a latitudinal direction, though whether this is the case or not I am not sure.
To watch this curious action through the glasses is most interesting. Each time there is a perceptible second or two during which the bird remains completely reversed, back to earth and breast to sky. The appearance presented is equally extraordinary, whether it makes the half roll and returns, or goes completely round. I have sometimes seen rooks make a turn over in the air, but this was more a disorderly tumble, recalling that of the peewit, and, though striking enough, was not nearly so extraordinary as this orderly and methodical, almost sedate, turning upside down. The feat is generally performed four or five times in succession, at intervals of some seconds, during which the steady flight is continued. Most often it is done in silence, but sometimes, at each roll over, the raven cries "pyar," a penetrating and striking note.
Sometimes these ravens would roll in this manner whilst pursued by or skirmishing with a gull, and once I saw one of them do so during a curious kind of skirmish or frolic—it was hard to tell its exact character—with a hooded crow. Whether the hooded crow turned itself almost at the same time in a manner somewhat or entirely similar, I am not quite sure, but it struck me that it did do so. Of course, one may very easily just miss seeing the action of a bird clearly, especially if there are two or more together, and it is then, often, very annoying to be left with no more than an impression, which may or may not be correct. It is more satisfactory, almost, to see nothing than not to be sure, but both impression and doubt should be stated, for both are facts, and should not be suppressed. But on no other occasion have I seen a hooded crow behave in this way, though I have watched them often. Once, but only once, I saw one indulging in an antic which was sufficiently striking, but of quite a different character. This bird would spring suddenly from the ground, mount up almost perpendicularly to a moderate height, and then descend again on the same spot or close to it, making a sudden lurch and half tumble in alighting. It did this some dozen times, but not always in so marked a manner, for sometimes the mount or tower was not straight up from this spring—as a mountain sheer from the sea—but arose out of what seemed an ordinary flight over the ground. As it descended for the last time another crow flew up to and alighted beside it in a manner which seemed to express an entry into its feelings. This was in East Anglia, on the last day but one of February, and I look upon it as a premature breaking out of the nuptial activities before the birds had taken wing to their more northerly breeding-places. As to these aerial antics of the ravens, I doubt if they were strictly nuptial, on account of their performance of them whilst skirmishing with gulls, or with the hooded crow.
These two ravens were most devoted guardians of their young, and they pursued a plan with me—for I was the only intruder on their island—which was well calculated to blind me with regard to their whereabouts, and would certainly have succeeded in doing so, had not the nest been so openly situated, and such a conspicuous object. They took up their station daily—and in this they never once varied—at a point on the cliffs considerably beyond the place where they had built their nest, and which commanded a wide outlook. As I came each morning along the coast, which rose gradually, I became visible to them whilst about as far from their nest on the one side as they were on the other, and the instant my head appeared over the brow of the hill they rose together with the croaking clamour I have mentioned, and circled about round their own promontory. This strategy could hardly have been improved upon had it been carefully thought out by a man, for in the first place my attention was at once directed to the birds themselves, and then if the likelihood merely of there being a nest had occurred to me, that part of the cliffs from which they rose, and about which they wheeled, would have seemed the most likely place in which to search for it. No doubt, had the nest been well concealed, the birds would have done better not to have shown themselves, but conspicuous as it was, they could hardly have adopted a better plan of getting me away from just that part of the coast where it was situated.
I have spoken in the last chapter of the extreme boldness of the smaller of the two skuas, and how, whether in sport or piracy, he chases birds much larger than himself. It was, therefore, something of a surprise to me when I observed one morning this bold buccaneer being himself pursued by another bird. This was one of a pair of curlews, birds that are as the spirit of the sad solitudes in which they dwell. It is, indeed, more as a part of the scene—that treeless, mist-enshrouded waste beneath grey northern skies, which they emphasise and add expression to—than in themselves that one gets to consider them. Just thickening with a shape the dank, moist atmosphere, seeming to have been strained and wrung out from the mist and rain and drizzle, they are, at most, but a moulded, vital part of these. They move like shadows on the mists, when they cry, desolation has found its utterance. And yet, for all this, their general appearance, with their long legs and neck, and immensely long sickle-shaped bill, is very much that of an ibis—insomuch, that seeing them in this bleak northern land, has sometimes almost a bizarre effect. This should seem quite irreconcilable with the other, and yet, though it certainly ought to be, somehow it is not, so that, at one and the same time, this opposite bird brings a picture, by looking like an ibis, of Egypt and the South, and is likewise the very incarnation of grey skies, of mist and morass. So strangely can contradictions be reconciled in the mind, or rather so well and impartially can we grasp two aspects of a thing when neither concerns us personally.
When they stand or walk slowly and sedately these curlews hold their long, slender necks very erect, and it is this, with the beak, that gives them their ibis-like character. When they run they lower the neck, and the quicker they go the lower do they hold it. In taking flight they sometimes make a few quick running steps with raised body, as though launching themselves on the air; but at other times they will rise from where they stand without this preliminary. In flight they may be called conspicuous, at any rate by contrast with the wonderful manner in which they disappear simply—"softly and silently vanish away"—when on the ground. This is by reason of their colouring, which on all the upper surface of the body and the outside of the wings is of a soft, mottled brown, which blends wonderfully with, or, rather, seems to become absorbed into the general surroundings of moor and peat-bog, so that they never catch the eye, and are simply gone the instant this is taken off them. But the plumage of the under surface of the body and of the inside of the wings is much lighter, and this becomes visible as the bird rises (as with the redshank), and alternates with the other as it flies around. It is thus—round and round in a wide circle—that a pair of them will keep flying when disturbed in their breeding-haunts. But though each bird is equally disturbed and anxious, and though their mournful cries answer each other like two sad complaining souls, yet they keep apart, and, on settling, do not run to each other. From the drear slope of a hill a wail goes up, and from another hill, or the cheerless hollow between, the sad sound is answered. Or one will fly wailing whilst the other wails and sits, or the two will follow each other along the ground, but without coming very near. Thus, in a kind of sad, solitary communion, they wail and lament, and so exactly is each the counterpart of the other, one might think that the prophet Jeremiah had been turned into a bird, which had subsequently flown asunder.
