The Bird Watcher in the Shetlands/Chapter 5
CHAPTER V
A VENGEFUL COMMUNITY
IT was terns, I think, who, when some killing Scotch naturalist or other had wounded one of their number, came down to it, pitifully, as it lay on the sea, and bore it away upon their backs and wings. I can better realise this incident now, after having walked about a ternery in these northern parts, and again tried the experiment—which in the south produced no special consequences—of interfering with their young. Upon my taking one of them in my hand, the whole community, amounting, perhaps, to several hundreds, gathered in one great, air-filling cloud, a little above my head, and with violent sweeps and piercing cries, seemed to threaten an actual attack. When I let the young thing flutter to the ground, and it moved and struggled upon it, the excitement was redoubled. It seemed as though they were animated with hope at seeing it out of my grasp, and as I took it up and let it go twice again, each time with the same result, I have little doubt that this was really the case. It was not only the two parents—assuming them to have been there—who attacked me. Many did so; many, too, seemed to feel, at some time, an extra degree of fury, whilst not a bird in the whole crowd but was violently and vengefully moved. These terns, as they clustered and darted about, resembled, or at least made me think of an angry swarm of wasps or hornets; but how different is the anger of insects to that of any other sort of animal! Though so much smaller, they attack without any hesitation or mistrust as to the result whatever. A hornet or an ant threatening merely when its nest was attacked seems an absurdity, whilst in a creature many times their size it is the idea of courage only that is presented to us.
Yet it was not all threatening with these terns, for as the excitement and hubbub increased several of them attacked me, though only with missile weapons. To be explicit, they excreted upon me, as they swept down, in such an irate "Take that!" sort of manner and with such precision of aim, that the intention was quite evident. This habit I had heard of, though not felt, before, for a south coast fisherman told me that he once had a dog which had developed a strong liking for tern's eggs, to gratify which he used to make egg-hunting and feasting expeditions along a line of beach where they lived, from which he would return in a most unseemly plight, owing to the birds having "dunged" him. I did not doubt this account at the time, and I have now this interesting confirmation of it, but though I myself walked amongst these southern terns and often took the young ones up in my hand, they never vented their displeasure on me in this particular way, nor were such swoops and threatenings as they made of so pronounced and violent a character. They mobbed a hare, however, in a much more determined way, and certainly pecked at it, though, at the distance, this was all I could say with certainty. It is interesting if a means of defence resorted to against animals only, by some colonies of these birds, is by others employed to repel the intrusion of man also. For the habit itself, I do not remember reading of it, either in the case of terns or any other bird or animal, except one with which Swift has made us familiar—Swift, that great misanthrope, who, by the sheer force of his satire, has anticipated to some extent the reasoned truth of Darwin. As I say, I can hardly doubt that these terns acted as they did with malice prepense, yet, as their conduct is, perhaps, susceptible of another interpretation, I ought to mention that the bombardment was not continuous, but occasional only—a dropping fire, so to speak. As far as I could observe, however, the act was always in combination with the plunging sweep down, which makes me certain that, if not the mere mechanical effect of intense excitement, it was prompted by hostility—to which latter view I strongly incline.
A little way farther on I found two quite tiny terns—the other was of a fair size—lying together in the nest. There was excitement when I took up these also, but not nearly so great as just before, except, perhaps, on the part of the two parents. The first young bird had assumed almost its final appearance, though not quite able to fly. I concluded, therefore, that this had something to do with the different degree of excitement shown by the terns as a whole, but when, after some while, I found and took up another baby, almost as big as the first, there was still less demonstration than in the case of the two fluffy ones—again excepting the parents. Perhaps the boiling point of communal fury that had been aroused by my first unlawful act was not to be again reached; but birds are certainly capricious in their actions, and there is no judging from one to the next.
But, taking them at their best, why are these northern terns so much fiercer and more vengeful than those which breed in the south? Of the disposition of the latter I have had ample time to judge, and, though there was always anger when I walked over the great bank crowded with their nests, yet its manifestations were of a more ordinary kind, nor, as I say, did I notice any very acute development of it when I lifted a young one from the ground. Sometimes I think these Shetlanders look slightly smaller than the English kind, and always they seem to me to be more waspish and irritable in their disposition. Are they, therefore, of a different species—the Arctic, instead of the common tern, or vice versâ? The two, indeed, are so much alike that only an ornithologist—as ornithologists tell us—is capable of distinguishing them whilst the birds are alive and at liberty. However, as the sole mark of distinction appears to consist in a hardly appreciable difference in the length of the tarsus, it is easier to understand the difficulty than how the ornithological eye, even, unsupported by a measuring-tape, manages to surmount it. But when would any member of a fraternity admit himself on a level with mankind in general, in regard to his particular cult? The thing is always to ramp on one's pedestal, though it be no higher than the houses over the way. Personally I doubt the validity of a specific distinction so attenuated as this; but be that as it may, terns, in their northern and southern homes, seem to differ somewhat in their natures, even as do the respective beaches on which they lay, with their surrounding scenery of sea and sky. How different are these one from another! Here, in these desolate and wind-swept isles, I, at least, though I have sometimes seen the sun, have never caught one glimpse of summer—nothing at all nearer to it than a somewhat fresher and very much rougher November. But on that other great bank, in the more genial climate of southern England, not only is it summer, sometimes—and that in spring—for hours together, but one may even be, for a while, in the tropics. How else could there be the mirage? Yet there it is, or, at any rate, something like it; for as one lies at length and gazes through the golden haze that seems to beat in waves upon the hot, parched shingle, lo! this is gone, and where it lay, all glaring, a blue pellucid lake, that seems to partake equally of the nature of sea and sky, lies now, cool and delightful. Into it terns, ever descending, seem to plunge or softly dip, as though it were the sea itself; and as they do so they either disappear altogether, becoming lost in azure haze, or are seen through it, dimly and vaguely, sitting or performing such actions as are proper to their shore life, amidst those strange new waters, from which others as constantly ascend. Gulls, too, and sometimes cormorants, may be there, whilst dove-cot pigeons, with familiar, yet now half phantasmal strut and bow, mingle occasionally, like little household Pucks, with the more poetic figures of this fairy dream. A dream, indeed, it is; but, more and more, it passes into one of far-off, sunnier lands—seen once, remembered now. Bluer becomes the sky—the sea; softer the air. Palm-trees wave, the long, bright breakers are bursting on a coral shore, the surf roars in, hissing and sparkling, the gulls are the surf-riders, England is no more.
