Master and Pupil: Hooded-Crow flying with Peewits.
"Late in the afternoon there is a pause and hush. The birds have ceased flying till dusk, and are either standing still or walking over the ground. One I can see motionless amidst the brown, tufted grass. No, not quite motionless. Ever and anon there comes the strained, grating call-note of another peewit, and then this one rears up the body and jerks the head a little back, then jerks it flexibly forward again. At first he does this in silence, but soon answering the cry. You see the thin little black bill divide as he bobs, and the sound comes out of it as though drawn by a wire—so roopy and raspy is it. Now he can contain himself no longer, but begins to walk about through the grass, making a devious course, and uttering the call at intervals. Very different is this note from the joyous, musical 'coo-oo-oo, hook-a-coo-ee, coo-ee.' Still, it is in harmony with nature, with the stillness, the sadness, the loneliness. This standing or pacing about whilst calling roopily, and, as it were, in a stealthy manner to each other, should be a very prosaic affair, one would think, for a pair of peewits after such glorious flying, but, no doubt, there is some excitement in it. Perhaps it is thought a little fast, as some slow things with us are, and hence the peculiar charm.
"Now these two birds are standing lazily on two of the black molehills which are all about the marshy land—some of them of a size beyond one's comprehension—and making the wire-drawn cry at intervals to each other. Lazily they stand, lazily they utter it, and seem as though they had taken up their roosting-place for the night. But when the night falls they will be hurrying shadows in it, and their cries will come out of the darkness, mingling with the bleatings of the snipe."
There is a sameness and yet a constant difference in the aerial sports and evolutions of peewits. It is like a continual variation of the same air or a recurrent thread of melody winding itself through a labyrinth of ever-changing notes. Parts of the melody are where two skim low over the ground in rapid pursuit of each other. One settles, the other skims on, then makes a great upward sweep, turns, sweeps down and back again, again rises, turns and sweeps again, and so on, rising and falling over the same wide space with the regular motions and long rushing swing of a pendulum. Each time it comes rushing down upon the bird that has settled, and each time, at the right moment, this one makes a little ascension towards it, sometimes floating above it as it passes, sometimes beneath, alighting again immediately afterwards. This may continue for some little time, the one bird passing backwards and forwards over or under the other as long as he is received in the same way. Gradually, however, these little sorties against him from being at first hardly more than balloon-jumps—springs with aid of wings—become more and more prolonged, and extended outwards into his own radius of flight. The bird making them no longer alights in the same or nearly the same place as where he went up, but farther and farther away from it, the figure is lost, or becomes indistinct, "as water is in water," till at last the two are flying and chasing each other again.
This upward sweep from near the ground—sometimes from nearly touching it—with its attendant sweep back again, is one of the greatest beauties of the peewit's flight—a flight that is full of beauties. He does it often, but not always in quite the same way; it is a varying perfection, for each time it is perfect, and sometimes it seems to vie with almost any aerial master-stroke. The bird's wings, as it shoots aloft, are spread half open, and remain thus without being moved at all. The body is turned sideways—sometimes more, sometimes less—and the light glancing on the pure soft white of the under part, makes it look like the crest of foam on an invisible and swiftly-moving wave. As the uprush attains its zenith, there is a lovely, soft, effortless curling over of the body, and the foam sinks again with the wave. Such motions are not flight, they are passive abandonings and givings-up-to, driftings on unseen currents, bird-swirls and feathered eddies in the thin ocean of the air. It is, I think, the cessation of all effort on the bird's part which makes the great loveliness here. The impetus has been gained in flight before—acres of moorland away sometimes—it "cometh from afar." The upward fall, the delicious, crested curl and soft, sinking swoon to the earth are all rest—rhythmical, swift-moving rest.
Another curious and extremely pretty performance—a familiar bar of that thread of melody, that "main theme" of the "movement"—is when two birds, one just a little behind the other, and at slightly different elevations, both make the same movements, in quick succession, the bird behind mimicking the one in front of him in a kind of aerial follow-my-leadership. Does the one pause and hang on extended wings that rapidly beat the air, the other does so too. Does it sail on a little, and then make a sideway dive, it is imitated in the same way, and thus, often for quite a little while, the two will understudy each other—for each, I think, may alternately become the leader. Again—if this is not merely a development of the above—two of them will hover on outstretched wings directly over and almost touching each other. Sometimes, indeed, they do touch, for the bird that is stretched above is continually trying to strike down on the other one with his wings, and often succeeds by making a sudden little drop on to him—a drop which is only of an inch or so—quite covering him up for a moment. Then, disjoining, they will flap along for some while, still close together, flashing out alternately dark and silver, as if showing their glints to each other, till in two "dying falls" they sweep apart, and skim the ground and double-loop the heavens.
When peewits seem thus to battle together with their wings, in the air, it may well be that they are really fighting, in which case we may perhaps assume that they are two males, and not male and female. But as what I shall have to say with regard to the stock-dove on this point may be applied to the peewit, and as I have better evidence in the case of the former bird, I will not dwell on it longer here.
But the question arises whether in many other cases, when the sporting birds would seem to be male and female, this is really the case. One is apt to think so at first, but when one sees, often, a third bird associate itself with a pair who are thus behaving, and join for a little in their antics, or when one of a pair desisting and alighting on the ground, the other continues to sport in precisely the same way with another bird, or when, again, the supposed lovers become two of a small flock or band, and all sport thus together, crossing and intermingling till they again separate: one must suppose that these evolutions, though they may be mostly of a nuptial character, are not sexual in the strictest sense of the term, but that the social element enters more or less largely into them. But amongst savages there are, I believe (if not, let us imagine that there are), dances, the theme of which is marriage, where sometimes men, sometimes women, sometimes men and women, dance together, all having in their mind the primitive ideas suggested by that great institution, men thinking of women, women of men, under every kind of grouping. One may suppose it to be thus with the peewits, as they sport with one another in the air during the nuptial season, in which case the social and sexual elements would be a changing and varying factor. One may say, indeed, that there can be no sexual sport or play into which the social element does not also, and necessarily, enter. This is, no doubt, true, strictly speaking, but the latter may be so merged in the former that practically it does not exist.
