I have no doubt that numbers of shags roost in these caverns during the night, for when I was lost on Raasey Isle in Skye, I came to a huge vaulted chamber in the cliffs, into which scores—perhaps hundreds—both of these birds and the common cormorant flew, after the sun had set. When they were all settled, every ledge, crevice, and pinnacle seemed tenanted by them, and never shall I forget the gloom, the grandeur, and the loneliness of this scene. I admired it, though naked, except for a torn pair of trousers which were half wet through. I should like to see them come flying into their caves here also, where I am not so forlorn; but the distance of my hut from this part of the shore, the lateness of the hour up to which the light lasts, and my having to cook my supper, makes this difficult, or, at least, inconvenient. But if I cannot see them fly in in the evening, I may see them fly out in the morning, and that should be "a sight for sair een."
Whilst rowing to these caves we had seen one black guillemot, or "tysty," flying over the sea with a fish in its bill, and another swimming with a young one by its side. The latter was of a greyish colour, and about a third smaller than the parent bird, which in shape and movements it closely resembled. These birds, therefore, breed in the Shetlands—a fact well known before, I believe; but I like to rediscover things. Another and more interesting thing that we saw was a seal swimming very fast, and leaping, at intervals, out of the water. I think I may use this expression, for if he did not leap quite free of it, he very nearly did, so as to show his whole body. He rose in a very bluff, bold way, with great impetus, as it seemed, and went straight, or nearly straight up, for a little, before falling forward again. Each time one seemed to hear the splash and the blow, but this was only in imagination, the distance being too great. When I say that this seal was swimming very fast I am giving my impression merely. All I saw was the leaps, which were quickly repeated, yet with a good space between each, and all in one direction. Between them, therefore, he must have been speeding along at a great pace, so that, each time he plunged up, it was as from a spring-board of impetus and energy. I do not remember reading of seals leaping thus out of the water, but Mr. Hoseason had seen them do so before, though not often. There was a fine joyous spirit in the thing—"there is" joy, as well as "sorrow on the sea."
It is good to see an animal like this in this United Kingdom of ours—or at least in its seas—for, for a moment, it makes one think one is out of it, and in some wilder, more life-teeming part of the world. It is hard to have to live in a country, glorified as being "a network of railways," and to have no taste for railways. Oh, wretched modern world of ugliness, noise, improvement and extermination, what a vile place art thou becoming for one who loves nature, and only cares for man in books!—the best books bien entendu.
DUCKS AND DIVERS
T
THE red-throated diver moves softly upon the gentle play of the ripples, seeming, rather, to float with the tide than to swim, for there is no defined swimming action. When it turns and goes the other way, it meets the opposing motion—the little dance of the sea—as if it were a ripple itself, assuming the shape of a bird. This shape is a graceful one, something between that of a grebe and a guillemot. One might say that a guillemot had been sent to a finishing-school and had very much profited by it; but this is not to imply that the grebe—I am thinking of Podiceps Cristatus—is slighted in the comparison—no bird that swims need think itself so. Much there is grebe-like in manner and action, and in shape, except for the crest. By the want of this, the bird, I think, rather gains than loses to the human eye, for handsome as the grebe's crest is, the delicate curve of head and neck is interrupted by it, and the effect is rather bizarre than beautiful—it loses something in purity, that beauty of the undraped statue, to which Cicero compares the style of Cæsar. The neck of the red-throated diver offers a wonderful example of delicate yet effective ornament. Down the back of it, and encroaching a little upon either side, run thin longitudinal stripes of alternate black and white, so cleanly and finely divided that they look as though they had been traced by a paint-brush in the hand of a Japanese artist. There is a gorget of rich ruddy chestnut on the throat, but the rest of it, with the head and chin, is of a very delicious plum-bloomy grey, which looks in the sunlight as though it would be purple if it dared, but were too modest—a lovely and æsthetic combination, soft, yet bright, and the whole with such a smoothness as no words can describe. There is another effect wrought by the sun, if it should happen to be shining, and if the bird should be swimming so as to give a profile view. It then looks as though there were a broad, white stripe—white, but having almost a prismatic brilliancy—along the contour-line of the nape. This appearance is most deceptive, and it is only when the bird turns its neck so as to show the several thin delicate stripings that one sees it to be illusory. It is produced, I think, by the light being reflected from the white stripes alone, so that the black ones between them are overlooked. Whatever may be the cause, the effect is most striking and lovely, and if the stripes themselves are due to sexual selection—which I do not doubt they are—this far more beautiful appearance, being the effect and crown of them, must assuredly also be. Here is a neck, then! and I have seen three, and once even seven, together!
In their way of diving, again, these birds resemble the grebes. Sometimes they go down with a very quiet little leap, but often they sink and disappear so gently and gradually that one is hardly conscious of what they are about till one sees them no more. As much as any creature, I think, they "softly and silently vanish away." Another habit which they have is shared by the cormorant and other sea-birds, and has often puzzled me. It is that of continually dipping their bills in the water and raising them up from it again, as though they were drinking, though that they should drink the salt sea like this, for hours at a time, seems a strange thing. What is the meaning of this action, which I have just seen a shag perform forty-six times in succession, at intervals of a few seconds, as if for a wager? And this was after having watched it doing the same thing for some time before. After the forty-sixth sip, as it were, this bird made a short pause, and then recommenced. Is this drinking, and, if not, what is it? The head and part of the bill are, each time, sunk in the water, so that, as the bird moves on, they plough it like the ram of a war-ship. Then, in a second or two, the head is raised, not so high indeed as in an unmistakable thirsty draught—which I do not remember at any time to have seen shags indulge in—but with much the action of drinking. The bill, it is true, is very little opened, hardly sufficiently so to be noticeable, but very little would allow of water entering it. But why should the bird drink like this? It cannot be that the salt water makes it more and more thirsty, for this, as with shipwrecked sailors, would produce evil consequences—probably death—but, of course, this is out of the question.
