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.
