Chapter XV: Part III: Nature Lore (2)

Text size

Many of our common weeds are very interesting plants to the botanist. They have to fight for their lives; and the way in which they scatter their seeds, and the power of those seeds to lie dormant for years waiting a chance to grow, are well worth study. It is a war between the farmer and wild nature, and when we look over our fields and pastures in spring and summer we see clearly enough that the farmer is not always the victor. In many a cornfield the oat crop seems to be merely incidental, while the hardier children of nature flourish in spite of its intrusion.

This is not as it ought to be. Even if they are otherwise harmless, the weeds use up a large part of the plant food in the soil, and they rob the young oats of the necessary light and air. In this way weeds prove an expensive crop to the farmer. It pays him to study their life-history so as to learn how they may be eradicated, and to spend some labour in the task of doing so.

A common pest in the Orkney cornfields is the “runcho” or “runchic,” known elsewhere by the name of charlock or wild mustard. Its pale-yellow flowers overtop the growing oats, and their unwelcome gleam makes some fields conspicuous for miles around. The form of the flower shows that the charlock belongs to the same family as the turnip and the cabbage and the fragrant wallflower of our gardens. The flower has four petals, and the cross-like arrangement of its six stamens, four long and two short, has given them their name of _Cruciferæ_, or cross-bearers. The seed-vessels, like those of the turnip, are in the form of a long, narrow pod with a partition running down the middle. The seeds are small and hard, and they grow only in a freshly-stirred soil with plenty of light and air. When a field is laid down in grass they make no sign of life, but when it is ploughed for the next crop of oats they spring up once more, and make it as gay as a flower-bed. Two kinds of this plant are found—the one, charlock, of a light yellow colour, common in peaty and clayey ground; and the other, wild mustard, of a deeper yellow, found in sandy soil.

1. False oat grass. 2. Chickweed. 3. Ragwort. 4. Prunella. 5. Wild mustard (_Brassica Sinapis_). 6. Charlock (_Raphanus Raphanistrum_). 7. Corn spurrey. 8. Sheep’s sorrel. 9. Common sorrel.]

Another showy weed is the yellow corn-marigold. This handsome flower seems more dainty in its choice of soil, and in some districts it is not common. A glance at the open flower shows its kinship to the “wee, modest, crimson-tipped” daisy. The so-called flower is not one, but a host of tiny flowers or florets growing upon a broad green disc called the receptacle. This compound or composite type of flower is found in a large number of common plants, named on this account _Compositæ_. Many of them are found in Orkney, and they are a very interesting as well as a numerous family.

One of the best known is the dandelion, a more beautiful flower than many which we grow in our gardens, and only its abundance prevents our admiring it. If we examine the florets of the dandelion, we see that each of them has a corolla forming a long yellow ribbon on the side farthest from the centre of the flower. In the corn-marigold only the outer florets have this ribbon, which forms a halo of rays round the central portion. In the daisy these rays are white, with the tips pink, especially underneath.

A well-known feature of the dandelion is the white down which it produces when in seed—a wonderfully beautiful arrangement for spreading its seeds far and wide to find room to grow. This is a common method of broadcast sowing among the Compositæ family. The thistles, which form a well-known section of that family, depend largely on their floating seeds in their struggle against the farmer. Some farmers seem to forget this fact, for, crowded in some corner of an old pasture, or in serried ranks by roadside and ditchside, we may see those armed foes allowed to blossom and send forth thousands of winged seeds to overrun the neighbouring fields, and even the neighbouring farms. A few hours’ work with a scythe would prevent the mischief. There might well be laws to prevent the careless spreading of weeds as there are to prevent the spreading of infectious disease among animals.

One of the Compositæ family is a common weed in Orkney pasture fields—the “tirsac” or ragwort. This is a coarse, vigorous plant, with a tough stalk about two feet in height, crowned with a spreading tuft of yellow daisy-shaped flowers. In fields where this weed is allowed to grow and multiply, it soon comes to occupy a large proportion of the whole area, and this means a considerable loss in the grazing value of the pasture.

The large family of the grasses includes some of the plants most useful to the farmer. All the grain crops, such as wheat, barley, and oats, are cultivated grasses, as are also the plants which are used for pasture and for hay. There are some wild grasses, however, which are very persistent and troublesome weeds. Some of these, like couch grass, spread more by creeping underground stems than by seeds. A common grass in Orkney is that known as “swine-beads,” from the knotted form of its underground stems. Its common name is false oat grass. It resembles small black oats, but is much taller. Cartloads of its beaded stems may be gathered from some fields when being prepared for turnips, and by so doing much trouble may be saved.

When a field is laid down in turnips or potatoes, the weeds have a hard struggle for life. Those of slow growth are checked by the ploughing and grubbing and harrowing, and later by the hoe and the scuffler. Yet there are a few which in a moist season spring up quickly and soon cover the drills. The common spurrey, with its narrow, sticky leaves growing in whorls, and its tiny white flowers which open only in the sun, is perhaps the best known. The chickweed is another common weed in such fields. These, however, if kept down at first by the hoe, are of too feeble growth to injure the crop among which they strive to find a living.

Sheep’s sorrel and common sorrel, both commonly known as “sooricks,” were more harmful half a century ago than they are at present. Cultivation and the rotation of crops have reduced their quantity, but their enormous power of spreading can be witnessed in a poor, thin, or peaty soil, where the crops, especially grass, are meagre. There they spread, and sometimes with such vigour that they push every other plant aside. Both kinds of sorrel are common. The one with arrow-shaped leaves is called common sorrel; that with spear-shaped leaves, sheep’s sorrel. Their leaves, which have a very acid taste, often turn reddish.

Another common and pretty little flower is prunella or self-heal. Whorls of green bracts and violet flowers form a dense, short spike. It grows from four to six inches high, and is to be met with on dry soils, and although fairly common in oats, flourishes best in second year’s grass. It is one of the large order of _Labiates_, a group which includes the dead-nettle and the hemp-nettle, and when abundant it is a clear indication of the exhaustion of some ingredients of the soil—often lime. When fields are brought to a high state of cultivation, or are near enough the seashore to get an abundant supply of sand, it almost disappears; but when they are impoverished, it soon returns.

These are only a few of the weeds which every farmer knows well. They are worth study, for it is only when we know how they grow and spread that we are able to prevent their increase. The cultivation and manuring of the soil and the sowing of seeds are only one side of the farmer’s work; he has to remove the wild growth as well as to promote the growth of what he sows. Otherwise his fields will bear two crops at a time, one of nature’s sowing and one of his own, and of these two the natural crop is likely to be the more flourishing.

HOME LIFE ON THE ROCKS.

Guillemots.

Nothing is more interesting than to look down from the summit of some precipice on to a ledge at no great distance below, which is quite crowded with guillemots. Roughly speaking, the birds form two long rows, but these rows are very irregular in depth and formation, and swell here and there into little knots and clusters, besides often merging into or becoming mixed with each other, so that the idea of symmetry conveyed is of a very modified kind, and may be sometimes broken down altogether. In the first row a certain number of the birds sit close against and directly fronting the wall of the precipice, into the angle of which with the ledge they often squeeze themselves. Several will be closely pressed together, so that the head of one is often resting against the neck or shoulder of another, which other will also be making a pillow of a third, and so on. Others stand here and there behind the seated ones, each being, as a rule, close to his or her partner. There is another irregular row about the centre of the ledge, and equally here it is to be remarked that the sitting birds have their beaks pointed towards the cliff, whilst the standing ones are turned indifferently. There are generally several birds on the edge of the parapet, and at intervals one will come pressing to it through the crowd in order to fly down to the sea, whilst from time to time others also fly up and alight on it, often with sand-eels in their beaks. On a ledge of perhaps a dozen paces in length there may be from sixty to eighty guillemots, and as often as they are counted the number will be found to be approximately the same.

Most of the sitting birds are either incubating or have young ones under them, which, as long as they are little, they seem to treat very much as though they were eggs. Much affection is shown between the paired birds. One that is sitting either on her egg or her young one—for no difference in the attitude can be observed—will often be very much cosseted by the partner who stands close behind or beside her. With the tip of his long, pointed beak he, as it were, nibbles the feathers (or, perhaps, scratches and tickles the skin between them) of her head, neck, and throat; whilst she, with her eyes half closed, and an expression as of submitting to an enjoyment—a “Well, I suppose I must” look—bends her head backwards, or screws it round sideways towards him, occasionally nibbling with her bill also amidst the feathers of his throat, or the thick white plumage of his breast. Presently she stands up, revealing the small, hairy-looking chick, whose head has from time to time been visible just peeping out from under its mother’s wing. Upon this the other bird bends its head down and cossets in the same way—but very gently, and with the extreme tip of the bill—the little tender young one. The mother does so too, and then both birds, standing side by side over the chick, pay it divided attentions, seeming as though they could not make enough either of their child or of each other. It is a pretty picture, and here is another one.

A bird—we will think her the female, as she performs the most mother-like part—has just flown in with a fish—a sand-eel—in her bill. She makes her way with it to the partner, who rises and shifts the chick that he has been brooding over from himself to her. This is done quite invisibly, as far as the chick is concerned, but you can see that it is being done.

The bird with the fish, to whom the chick has been shifted, now takes it in hand. Stooping forward her body, and drooping down her wings, so as to make a kind of little tent or awning of them, she sinks her bill with the fish in it towards the rock and then raises it again, and does this several times before either letting the fish drop or placing it in the chick’s bill—for which it is I cannot quite see. It is only now that the chick becomes visible, its back turned to the bird standing over it, and its bill and throat moving as though swallowing something down. Then the bird that has fed it shifts it again to the other, who receives it with equal care, and bending down over it, appears—for it is now invisible—to help or assist it in some way. It would be no wonder if the chick had wanted assistance, for the fish was a very big one for so small a thing, and it would seem as if he swallowed it bodily. After this the chick is again treated as an egg by the bird that has before had charge of him—that is to say, he is sat upon, apparently, just as though he were to be incubated.

On account of the closeness with which the chick is guarded by the parent birds, and the way in which they both stand over it, it is difficult to make out exactly how it is fed; but I think the fish is either dropped at once on the rock, or dangled a little for it to seize hold of. It is in the bringing up and looking after of the chick that one begins to see the meaning of the sitting guillemots being always turned towards the cliff, for from the moment that the egg is hatched one or other of the parent birds interposes between the chick and the edge of the parapet. Of course I cannot say that the rule is universal, but I never saw a guillemot incubating with its face turned towards the sea, nor did I ever see a chick on the seaward side of the parent bird who was with it.

I observed that the chick—even when, as I judged by its tininess, it had only been quite recently hatched—was as alert and as well able to move about as a young chicken or partridge; but whilst possessing all the power, it appeared to have little will to do so. Its lethargy—as shown by the way in which, even when a good deal older, it would sit for hours without moving from under the mother—struck me as excessive; and it would certainly seem that on a bare, narrow ledge, to fall from which would be certain death, chicks of a lethargic disposition would have an advantage over others who were fonder of running about.

The young guillemot is fed with fish which are brought from the sea in the parent’s bill, and not—as in the case of gulls—disgorged for them after having been first swallowed. It is, however, a curious fact that the fish when thus brought in are, sometimes at any rate, headless. The reason of this I do not know, but with the aid of glasses I have made quite certain of it, and each time it appeared as though the head had been cleanly cut off. Moreover, on alighting on the ledge the bird always has the fish (a sand-eel, whenever I saw it) held lengthways in the beak, with the tail drooping out to one side of it, and the head part more or less within the throat—a position which seems to suggest that it may have been swallowed or partially swallowed—whereas puffins and razor-bills carry the fish they catch crosswise, with head and tail depending on either side.

I have once or twice thought that I saw a bird which just before had no fish in its bill all at once carrying one. But I may well have been mistaken; and it does not seem at all likely that the birds should usually carry their fish, and thus subject themselves to persecution, if they could disgorge it without inconvenience. With regard to the occasional absence of the head, perhaps this is sometimes cut off in catching the fish.

Seals.

Quite near to where I watch the guillemots there is a little iron-bound creek or cove, walled by precipice, guarded by mighty “stacks,” and divided for some way into two by a long rocky peninsula running out from the shore. On the rocks in one of these alcoves were lying eight seals, which were afterwards joined by another, making nine, whilst in the adjoining one were four—also, as it happened, joined by another, as I watched—making fourteen in all: such a sight as I had never seen before.

I watched these seals of mine on this, my first meeting with them, for a considerable time from the top of the cliffs—the glasses giving me a splendid view—and soon knew more about them than I had done before, and got rid of some popular errors. For instance, I had always imagined that seals had one set attitude for lying on the rocks—namely, flat on their bellies—a delusion which every picture of them in this connection had helped to foster. Imagine my surprise and delight when it burst upon me that only some three or four were in this attitude, and that even these did not retain it for long. No; instead of being in this state of uninteresting orthodoxy, they lay in the most delightful free-thinking poses, on their sides, showing their fine, portly, columnar bellies in varying degrees and proportions; whilst one utter infidel was right and full upon his broad back, yet looked like the carved image of some old Crusader on the lid of his stone sarcophagus. Every now and then they would give themselves a hitch, and bring their heads up, showing their fine round foreheads and large mild eyes; a very human—mildly human—and extremely intelligent appearance they had, looking down upon them from above. Again, they had the oddest or oddest-appearing actions, especially that of pressing their two hind feet or flippers together, with all their five-webbed toes spread out in a fan, with an energy and in a manner which suggested the fervent clasping of hands. Then they would scratch themselves with their fore feet lazily and sedately, raising their heads the while, looking extremely happy, having sometimes even a beatific expression. And then again they would curl themselves a little and roll more over, seeming to expatiate and almost lose themselves in large, luxurious ease—more variety and expression about them lying thus dozing than one will see in many animals awake and active.

Even in this little time I learnt that they were animals of a finely touched spirit, extremely playful, with a grand sense of humour, and filled “from the crown to the toe, top-full” of happiness. Thus one that came swimming up the little quiet bay, in quest of a rock to lie upon, seemed to delight in pretending to find first one and then another too steep and difficult to get up on (for obviously they were not), and would fling himself from off them in a sort of little sham disappointment, gambolling and rolling about, twisting himself up with seaweed, and generally having a most lively, solitary romp. A piece of bleached spar, some four or five feet long, happened—and I am glad that it happened—to be floating in the water at quite the other side of the creek and, espying it, this delightful animal swam over to it, and began to play with it as a kitten might with a reel of cotton or a ball of worsted. More frolicsome, kitten-hearted, and withal intelligent play I never saw. He passed just underneath it, and, coming up on the opposite side, rolled over upon it, cuffed it with one fore foot, again with the other, flipped it then with his footy tail as he dived away, and returning, in a fresh burst of rompiness, waltzed round and round with it, embracing it, one might almost say. At last, going off, he swam to a much steeper rock than any he had made-believe to find so difficult, and, scrambling up it with uncouth ease, went quietly to sleep in the best possible humour.

What intelligence all this shows! Much more, I think, than the sporting of two animals together. This seal was alone, saw the floating spar at a distance, and swam to it with the evident intention of amusing himself in this manner. Later, another seal played with this same spar in much the same way; yet both of them seemed to be quite full-grown animals.

Then I saw something which looked like a spirit of real humour, as well as fun. Three seals were lying on a slab of rock together, and one of them, raising himself half up, began to scratch the one next him with his fore foot. The scratched seal—a lady, I believe—took it in the most funny manner, a sort of serio-comic remonstrance, shown in action and expression: “Now do leave off, really. Come now, do leave me alone”—and when this had reached a climax the funny fellow left off and lay still again; but as soon as all was quiet, he heaved up and began to scratch her again. This he did—and she did the other—three times, at the least, and if not to have a little fun with her I can hardly see why.

Shags.

Now I have found a nest with the bird on it, to see and watch. It was on a ledge, and just within the mouth of one of those long, narrowing, throat-like caverns into and out of which the sea, with all sorts of strange, sullen noises, licks like a tongue. The bird, who had seen me, continued for a long time afterwards to crane about its long neck from side to side or up and down over the nest, in doing which it had a very demoniac appearance, suggesting some evil being in its dark abode.

As it was impossible for me to watch it without my head being visible over the edge of the rock I was on, I collected a number of loose flat stones that lay on the turf above, and, at the cost of a good deal of time and labour, made a kind of wall or sconce with loopholes in it, through which I could look and yet be invisible. Presently the bird’s mate came flying into the cavern, and wheeling up as it entered, alighted on a sloping slab of the rock just opposite to the nest. For a little both birds uttered low, deep, croaking notes in weird unison with the surroundings and the sad sea-dirges, after which they were silent for a considerable time, the one standing and the other sitting on the nest _vis-à-vis_ to each other. At length the former, which I have no doubt was the male, hopped across the slight space dividing them on to the nest, which was a huge mass of seaweed. There were now some more deep sounds, and then, bending over the female bird, the male caressed her by passing the hooked tip of his bill through the feathers of her head and neck, which she held low down the better to permit of this. The whole scene was a striking picture of affection between those dark, wild birds in their lonely wave-made home.

The male bird now flies out to sea again, and after a time returns carrying a long piece of brown seaweed in his bill. This he delivers to the female, who takes it from him and deposits it on the heap, as she sits. Meanwhile the male flies off again, and again returns with more seaweed, which he delivers as before; and this he does eight times in the space of one hour and forty minutes, diving each time for the seaweed with the true cormorant leap. Sometimes the sitting bird, when she takes the seaweed from her mate, merely lets it drop on the heap, but at others she places and manipulates it with some care. All takes place in silence for the most part, but on some of the visits the heads are thrown up, and there are sounds—hoarse and deeply guttural—as of gratulation between the two.

The nest of the shag is continually added to by the male, not only while the eggs are in process of incubation, but after they are hatched, and when the young are being brought up. In a sense, therefore, it may be said to be never finished, though for all practical purposes it is so before the female bird begins to sit. That up to this period the female as well as the male bird takes part in the building of the nest I cannot but think, but from the time of my arrival on the island I never saw the two either diving for or carrying seaweed together. Once I saw a pair of birds together high up on the cliffs, where some tufts of grass grew in the niches. One of these birds only pulled out some of the grass, and flew away with it, accompanied by the other.

It is not only seaweed that is used by these birds in the construction of the nest. In many that I saw grass alone was visible, though I have no doubt seaweed was underneath it; and one in particular had quite an ornamental appearance, from being covered all over with some land plant having a number of small blue flowers; and this I have observed in other nests, though not to the same extent. I think it was on this same nest that I noticed the picked and partially bleached skeleton—with the head and wings still feathered—of a puffin. It had, to be sure, a sorry appearance to the human—at least to the civilized human—eye, but if it had not been brought there for the sake of ornament, I can think of no other reason; and brought there or at least placed upon the nest by the bird it must almost certainly have been. The brilliant beak and saliently-marked head of the puffin must be here remembered. Again, fair-sized pieces of wood or spar, cast up by the sea and whitened by it, are often to be seen stuck amongst the seaweed, and on one occasion I saw a bird fly with one of these to its nest and place it upon it. In all this, as it seems to me, the beginnings of a tendency to ornament the nest are clearly exhibited.

Both the sexes share in the duty and pleasure of incubation, and (as in some other species) to see them relieve each other on the nest is to see one of the prettiest things in bird life. The bird that you have been watching has sat patiently the whole morning, and once or twice, as it rose in the nest and shifted itself round into another position on the eggs, you have seen the gleam of them as they lay there “as white as ocean foam in the moon.” At last, when it is well on in the afternoon, the partner bird flies up and stands for some minutes preening itself; while the one on the nest, who is turned away, throws back the head towards it, and opens and shuts the bill somewhat widely, as in greeting, several times. The new-comer then jumps and waddles to the farther side of the nest, so as to front the sitting bird, and sinking down against it with a manner and action full both of affection and a sense of duty, this one is half pushed, half persuaded to leave, finally doing so with the accustomed grotesque hop. It has all been done nearly in silence, only a few low, guttural notes having passed between the birds whilst they were close together. Just in the same way the birds relieve each other after the eggs have been hatched, and when the young are being fed and attended to.

A shag is sitting on her nest with the young ones, whilst the male stands on a higher ledge of the rock a yard or so away. He now jumps down and stands for a moment with head somewhat erected and beak slightly open. Then he makes the great pompous hop which I have described before, coming down right in front of the female, who raises her head towards him, and opens and closes the mandibles several times in the approved manner. The two birds then nibble, as it were, the feathers of each other’s necks with the ends of their bills, and the male takes up a little of the grass of the nest, seeming to toy with it. He then very softly and persuadingly pushes himself against the sitting bird, seeming to say, “It’s my turn now,” and thus gets her to rise, when both stand together on the nest over the little ones. The male then again takes up a little of the grass of the nest, which he passes towards the female, who also takes it, and they toy with it a little together before allowing it to drop. The insinuating process now continues, the male in the softest and gentlest manner pushing the female away, and then sinking down into her place, where he now sits, whilst she stands beside him on the ledge. As soon as the relieving bird has settled itself amidst the young, and whilst the other one is still there—not yet having flown off to sea—it begins to feed them. Their heads—very small, and with beaks not seeming to be much longer in proportion to their size than those of young ducks—are seen moving feebly about, pointing upwards, but with very little precision. Very gently, and seeming to seize the right opportunity, the parent bird takes first one head and then another in the basal part, or gape, of his mandibles, turning his own head on one side in order to do so, so that the rest of the long bill projects sideways beyond the chick’s head without touching it. In this connection, and while the chick’s head is quite visible, little, if any, more than the beak being within the gape of the parent bird, the latter bends the head down and makes that particular action as of straining so as to bring something up which one is familiar with in pigeons. This process is gone through several times before the bird standing on the ledge flies away, to return again in a quarter of an hour with a piece of seaweed, which is laid on the nest.

As the chicks become older they thrust the head and bill farther and farther down the throat of the parent bird, and at last to an astonishing extent. Always, however, it appeared to me that the parent bird brought up the food into the chicks’ bills in some state of preparation, and was not a mere passive bag from which the latter pulled fish in a whole state. There were several nests all in unobstructed view, and so excellent were my glasses that, practically, I saw the whole process as though it had been taking place on a table in front of me. The chicks, on withdrawing their heads from the parental throat, would often slightly open and close the mandibles as though still tasting something, in a manner which one may describe as smacking the bill; but on no occasion did I observe anything projecting from the bill when this was withdrawn, as one would expect sometimes to be the case if unmodified fish were pulled up. Always, too, the actions of the parent bird suggested that particular process which is known as regurgitation, and which may be observed with pigeons, and also with the night-jar.

Young shags are at first naked and black, also blind, as I was able to detect through the glasses. Afterwards the body becomes covered with a dusky gray down, and then every day they struggle more and more into the likeness of their parents. They soon begin to imitate the grown-up postures, and it is a pretty thing to see mother and young one sitting together with their heads held stately upright, or the little woolly chick standing up in the nest and hanging out its thin little featherless wings, just as mother is doing, or just as it has seen her do. At other times the chicks lie sprawling together either flat or on their sides. They are good tempered and playful, seize hold playfully of each other’s bills, and will often bite or play with the feathers of their parent’s tail. In fact, they are a good deal like puppies, and the heart goes out both to them and to their loving, careful, assiduous mother and father.

When both birds are at home, the one that stands on the rock, by or near the nest, is ready to guard it from all intrusion. Should another bird fly on to the rock and alight, in his opinion, too near it, he immediately advances towards him, shaking his wings, and uttering a low grunting note which is full of intention. Finding itself in a false position, the intruding bird flies off; but it sometimes happens that when two nests are not far apart, the sentinels belonging to each are in too close a proximity and begin to cast jealous glances upon one another. In such a case neither bird can retreat without some loss of dignity, and, as a result, there is a fight.

I have witnessed a drama of this nature. The two locked their beaks together, and the one which seemed to be the stronger endeavoured with all his might to pull the other towards him, which the weaker bird, on his part, resisted as desperately, using his wings both as opposing props and to push back with. This lasted for some while, but the pulling bird was unable to drag the other up the steeply-sloping rock, and finally lost his hold. Instead of trying to regain it, he turned and shuffled excitedly to the nest; and when he reached it, the bird sitting there stretched out her neck towards him, and opened and shut her beak several times in quick succession. It was as if he had said to her, “I hope you observed my prowess. Was it well done?” and she had replied, “I should think I did observe it. It was indeed well done.” On the worsted bird’s ascending the rock to get to his nest, the victorious one ran, or rather waddled, at him, putting him to a short flight up it. This bird was also cordially received by his own partner, who threw up her head and opened her bill at him in the same way, as though sympathizing, and saying, “Don’t mind him; he’s rude.” In such affairs, either bird is safe as soon as he gets within close distance of his own nest; for it would be against all precedent, and something monstrous, that he should be followed beyond a charmed line drawn around it.

THE BIRDS OF SULE SKERRY.

Sule Skerry is a tiny, barren, surf-bleached islet, lying far out in the open ocean, thirty-two miles west from Hoy Head, about the same distance from Cape Wrath, and thirty miles from the nearest land, Farrid Head, in Sutherlandshire. The Skerry, roughly rhomboidal in outline, is about half a mile in length and a quarter of a mile in its greatest width, and attains a height of only forty-five feet in its central part. All round the shore is a belt of bare, jagged rock, where the wash of the great Atlantic waves prevents any vegetation from finding a foothold, and of the thirty-five acres or so which form the entire area of the island only some twelve are covered with a mossy, vegetable soil.

Lying, as it does, right in the track of trading vessels, this low islet, together with the Stack, which rises to a height of more than a hundred feet some four and a half miles to the south-westward, formed a death-trap to many a ship, which was, no doubt, afterwards merely reported as “missing,” and its shores when visited were rarely found without some stranded wreckage to tell of the unrecorded tragedies of the winter seas. It was not till the year 1892 that steps were taken to mark this dangerous rock, but three years later saw the completion of Sule Skerry Lighthouse, a massive tower of a hundred feet in height, with a powerful light visible for a distance of eighteen miles.

Sule Skerry is no longer either a dangerous or a lonely islet when compared with its former state. The three lightkeepers who are always on duty, together with their goats, poultry, and rabbits, give quite an inhabited air to the place—probably too much so for the comfort of the original occupants, the flocks of birds which find on it either a permanent home or a temporary dwelling-place. Sule Skerry is an ideal place for observation of the birds which frequent our islands, both from the immense numbers of them which nest there, and from the absence of high cliffs or inaccessible rocks. Luckily for us, one of the lightkeepers formerly on this station, Mr. Tomison, a native of Orkney, was a man unusually well qualified for such observation, and he has recorded much that is of interest regarding the bird life of the Skerry. From one of his papers on this subject we quote the following interesting pages.

The Residenters.

The birds of Sule Skerry may be divided into three classes—the residenters, the regular visitors, and the occasional visitors. The class of residenters is represented by the great black-backed gull, the herring gull, the shag or green cormorant, and the meadow pipit.

The great black-backed gull is one of the handsomest birds of the gull family, but owing to its destructive propensities amongst small birds, rabbits, and occasionally young lambs, a continual warfare has been waged against it for years by farmers and gamekeepers, until now it is almost entirely banished to the outlying parts of the country. Before the lighthouse was erected on Sule Skerry, large numbers of this species frequented the island; but the lightkeepers found them such arrant thieves that they reduced their numbers considerably. There are still about twenty pairs resident on the island all the year round, and they seem to find plenty of food either on land or at sea. Their breeding-time is in May, and sometimes as late as June. When the young are hatched the parents are continually on the lookout for food, and I have often seen them swoop down and seize young rabbits. Frequently they make desperate efforts to capture the old rabbits, but never successfully. They lay three eggs in a nest composed of withered grass, and the process of incubation lasts about four weeks.

A small colony of herring gulls stays on the island all the year round, but in summer vast flocks of them are in evidence when the herrings are on the coast. Only the residents remain to breed, and about a dozen pairs annually rear their young and spend their whole time in the vicinity. Some of the young must emigrate to a more genial climate, for although rarely disturbed their numbers are not increasing. They lay three eggs early in May, and sit about four weeks. When hatched, the young immediately leave the nest, and are so like the surrounding rocks in colour that when they lie close it is almost impossible to discover them. When hunting for food for their offspring, these gulls are almost as great a pest as their cousins, the great black-backed, and are more audacious thieves.

The most numerous of the residenters are the scarfs. In summer and winter they are always on the island, and apparently there is an abundant supply of suitable food in the vicinity, for they never go far away. During winter they congregate on the rocks in large flocks or colonies, and they have become so accustomed to man’s presence that they fly only when one approaches within a few yards of them. In very stormy weather they seek refuge in some sheltered spot, far enough away from the coast-line to be safe from the encroaching waves, and only when frightened by any one approaching too near do they choose what is, in their opinion, the lesser of two evils, and seek safety in flight. With the advent of spring they, like all other birds, turn their thoughts to love. Their comparatively homely winter dress gradually changes to one more appropriate to this sentiment and more in harmony with the imposing surroundings. Early in the year their plumage assumes a greener tint, and the graceful tuft or crest on the top of the head becomes more and more prominent. This crest practically disappears about the end of June, and seems to be a decoration in both sexes only during the nuptial season. Usually they manage to get through with their love-making and selecting of partners by the middle of March, after which the operations of nest-building are undertaken.

In Orkney we associate a scarf’s nest with some almost inaccessible cliff, but such is not the case on Sule Skerry, for the simple reason that there are no cliffs. The nests are built all over the island, but principally near the coast-line; and the sociableness of the bird’s disposition shows itself in this fact, that they tend to crowd their nests together in certain selected spots, to which they return year after year. One place in particular, a patch of rough, rocky ground from forty to fifty yards square, I have named the scarf colony on account of its numerous population during the breeding season. Here in 1898 I counted fifty-six nests.

As to the materials used for nest-building, these are principally seaweed and grass, but the scarf is not very particular as to details, and uses anything that will suit the purpose. I have found pieces of ordinary rope, even wire rope, and small pieces of wood used, and a very common foundation is the skeleton of a rabbit which has died during the winter. During building operations I have observed that one bird builds and the other brings the materials. After all has been completed, three, four, and sometimes five eggs are laid. Three is the most common number; five is rare. During incubation the one bird relieves the other periodically. It is a common sight to see one come in from the sea, sit down at the edge of the nest, and hold a long palaver with its mate. The sitting bird then gets up and flies out to sea, the other taking its place.

When the young come out of the egg they are entirely naked, of a dark sooty colour, and particularly ugly. Towards the end of the first week of their existence a coating of down begins to grow, followed by feathers in about three weeks. As near as I can judge from observation, the bird is fully fledged in five weeks from the time of hatching.

The only other residenter is the meadow-pipit, tit-lark, or moss-cheeper. It is the only small bird that remains on the island all the year round. It nests generally in May, and lays five or six eggs. It is said that two broods are raised in the season, but I have never noticed that here. Towards the end of summer they are to be seen in considerable numbers, but in September and October the island is visited by kestrels, who soon thin them down.

The Regular Visitors.

The regular visitors are puffin, razor-bill, common guillemot, black guillemot, oyster-catcher, tern, eider duck, kittiwake, stormy petrel, curlew, snipe, turnstone, and sandpiper. In this list I have advisedly placed first the puffin, or tammynorie, or bottlenose, or coulterneb, or pope, or sea-parrot, for it is a well-known and well-named bird. In point of interest it undoubtedly takes the first place among all our feathered friends. Its remarkable appearance, its activity, its assertive disposition, and the regularity of its habits, compel the attention of the most careless observer.

At one time puffins were much in demand for food. An old history of the Scilly Islands tells us that in 1345 the rent of these islands was three hundred puffins. In 1848, on account of the bird having got scarcer, and consequently more valuable, the rent was fifty puffins. We are also led to understand that the young birds, being plump and tender, were more highly esteemed than their more elderly and tougher relatives.

The most remarkable feature of this curious bird is its beak, the peculiarities of which are its enormous size compared with the size of the body, and its brilliant colours—blue, yellow, and red. For a long time it was a puzzle that occasional dead specimens found washed ashore in winter had a beak very much smaller and destitute of bright colours. It has now been ascertained that the outer sheath is moulted annually, being shed on the approach of winter and replaced at the return of the breeding season.

To give any idea of their numbers on Sule Skerry is an almost impossible task, for when they are on the island they are hardly ever at rest. The air is black with them, the ground is covered with them, every hole is tenanted by them, the sea is covered with them. They are here, there, and everywhere.

They first make their appearance early in April, and spend from eight to twelve days at sea before landing, coming close in round the island in the forenoon and disappearing at night. Before landing they fly in clouds round the place, and after having made a survey to see that all is right, they begin to drop in hundreds, till in half an hour every stone and rock is covered. They do not waste time, but start at once to clear out old holes and make new ones, and for burrowing they can easily put a rabbit in the shade. Those who are not engaged in digging improve the shining hour by fighting, and for pluck and determination they are hard to beat. They are so intent on their work that I have often seized the combatants, and even then they were unwilling to let go their hold of each other; but when they do, it is advisable for the person interfering to let go also, if he would avoid a rather unpleasant handshake.

After spending a few hours on the island they all disappear, and do not usually land again for two days; but when they do come back the second time there is no ceremony about their landing. They come in straggling flocks from all points of the compass, and resume their digging and fighting. They continue in this manner, never remaining ashore all night till the first week of May. They spend very little time on the construction of their nests, which consist merely of a few straws. The greater number burrow in the dry, peaty soil, and their holes will average at least three feet underground; but there are also an immense number that lay amongst loose rocks and stones on the north side of the island. The eggs laid there are always clean and white until the young bird is hatched; but those laid underground in a day or two become as brown as the soil, and seem more like a lump of peat than an egg. During the time of incubation, which lasts a month, those not engaged in hatching spend their time in fishing and resting on the rocks, and as a pastime indulge in friendly sparring matches.

One easily knows when the young are hatched by seeing the old birds coming in from sea with herring fry or small sand-eels, which are carried transversely in their bills, from six to ten at a time. The sole work of the parent birds for the next three or four weeks is fishing and carrying home their takes to the young. Very little time is given to nursing. They remain in the hole just long enough to get rid of their burden, and then go to sea again. As the young ones grow, the size of the fish brought home increases. At first it is small sand-eels from one and a half to two inches long, but at the end of a fortnight small herrings and moderate-sized sand-eels are the usual feeding. I noticed an old bird fly into a hole one day with a bigger fish than usual, and, to see what it was, I put in my hand and pulled out both birds. The tail of the fish was just disappearing down the young one’s throat, but I made him disgorge his prey, and found it to be a sand-eel eight inches long. How that small bird could find room for such a dinner was really wonderful.

At first the young are covered with a thick coating of down, and probably their appearance at this stage has given rise to the name “puffin,” meaning a “little puff.” In a fortnight the white feathers on the breast begin to show, and the birds are fully fledged in four weeks, when they at once take to the water. As soon as they go afloat, young and old leave the place, and about the middle of July one can easily see that their numbers are decreasing, the end of August usually seeing the last of them.

There is a considerable colony of razor-bills on the island. Their time of arrival is about the same as that of the puffin, but they make no commotion when they come. They seem to slip ashore, and always keep near the coast-line, ready to fly to sea when any one approaches. They begin laying towards the end of May, and lay one egg on the bare rock, usually under a stone, but in some cases on an exposed ledge. During incubation one bird relieves the other, for if the egg were left exposed and unprotected the black-backed gull would very soon appropriate it. Some authorities say that the male bird brings food to its mate; but I have never observed this, though I have watched carefully to see if such were the case The young remain in the nest, or, to speak more correctly, on the rock, for about two weeks if not disturbed, and I have seen a young one remain ashore until covered with feathers, which would mean about four weeks from the time of hatching. They all, young and old, leave early in August. I am sorry to say they are becoming scarcer every year, chiefly on account of their shyness and fear of man.

The common guillemots are scarce. Their great haunt in this vicinity is the Stack. There they are to be seen in myriads on the perpendicular side of the rock facing the west. Only two or three pairs take up their abode on the island; in fact their numbers scarcely entitle them to be called Sule Skerry birds. The few young ones I have seen are carried to the water as soon as they are hatched—at least they disappear the same day.

Black guillemots or tysties are plentiful. Their time of arrival is about the middle of March, but they are rarely seen ashore before the end of April. Their nests are to be found in out-of-the-way crevices or under stones, and are not easily discovered on account of the extraordinary watchfulness of the birds and their care not to be caught on or near their nests. They lay two eggs, and the young are fully feathered before going afloat. They remain about the island till the end of September.

The first of all the visitors to arrive are the oyster-catchers. They first put in an appearance about the end of February, when their well-known cry denotes that the long, dreary winter is over. They spend their time till the end of March chiefly feeding along the coast-line; but after that time they pair, and are seen all over the island. About the end of May they lay three eggs in a nest composed of a few small stones; and when the young are hatched the noise of the old birds is perfectly deafening on the approach of an intruder, and even when no one is annoying them the clamour they make almost amounts to a nuisance. On calm, quiet nights it is hardly possible to sleep for them, and one feels inclined to get out of bed and shoot them down wholesale. The young leave the nest as soon as hatched, and are rarely seen, for on hearing the warning cry of the parent bird they at once hide among the long grass or under stones, and on one occasion I found a pair some distance underground in a rabbit’s hole. They all leave the island during the first half of September.
