GUILLEMOT.
Of all the various sea birds that cluster on the cliffs of Albion this species, the Uria troile of most modern ornithologists, is by far the commonest, and of the present family of birds the most widely distributed. During summer it may be met with in colonies of varying numbers, here and there on most of our rocky coasts, from the Scilly Islands to the Shetlands, from Flamborough Head in the east to the Blaskets in the west. Not, perhaps, so familiar to the sea-side wanderer as the Gull, whose ærial habits bring it more frequently into notice, the Guillemot, nevertheless, is a seldom absent feature of marine bird life. It is gregarious and social at all times, but joins into greatest companies during the season of reproduction. When the nesting season has passed the birds spread themselves more generally along the coast and out at sea, and it is at such times that they are most ubiquitous. Between October and March the Guillemot may often be met with swimming close in shore, in quiet bays, and especially in the neighbourhood of fishing villages. On these occasions it is not particularly shy, and will allow a sufficiently close scrutiny, but it is ever wary, diving at the least alarm, and appearing again well out of danger. The Guillemot swims well and buoyantly; it also dives with remarkable agility, and obtains most of its food whilst doing so. The Guillemots are rarely seen upon the land after the young have quitted their birthplaces; they spend their entire time upon the sea, seeking shelter during rough weather in bays or under the lee of headlands, but not unfrequently great numbers perish in a gale, their dead bodies strewing the coast where the tide has cast them ashore. Except during the breeding season the Guillemot flies very little, but during that period it often feeds far from its rocky haunts, and may then be seen, especially at eventide, flying in little bunches, or in compact flocks, swiftly and silently just above the waves, returning to them. The food of this bird is almost exclusively composed of fish, especially such small species as pilchards and sprats; it is also extremely partial to the fry of the herring and the pollack. Few birds are more expert at catching fish than the Guillemot; it dives after them, and chases them beneath the surface with marvellous speed and unerring certainty. In this chase of fish it sometimes comes to grief by getting entangled in the drift-nets. The Guillemot is a remarkably silent bird. I have repeatedly been amongst thousands of these birds, both at sea and on the rock stacks where they breed, and the only sound I have ever heard them utter is a low, grunting noise. My experience has been chiefly confined to the earlier part of the breeding season, and the autumn and winter months. It would appear, though, that when the young are partly grown the birds become more noisy, for Gätke describes their cries at the breeding-stations as a “confused noise of a thousand voices, the calls of the parent birds—arr-r-r-r, orr-r-r-r, err-r-r-r, and mingled with these the countless tiny voices of their young offspring on the face of the cliff—irr-r-r-idd, irr-r-r-idd—uttered in timid and anxious accents.” I should here remark that the Guillemot never flies over the land, never flies inland from the rocks, but always when disturbed unerringly makes for the sea, which is almost, if not quite, as much its element as the air.
The actions of the Guillemot are interesting enough upon the sea, few sights being prettier than a number of these birds busily engaged in capturing their finny food; but the most attractive scenes in the life of this bird are to be witnessed at its breeding places. Formerly these were much more numerous than is now the case, especially in England, but there, on the southern coast line notably so, many a large colony has disappeared for ever, and many another has been sadly reduced in numbers. The distribution of the Guillemot becomes much more local during summer, the birds crowding in vast numbers to certain time-honoured spots. Fortunately some of these still remain fairly accessible to the lover of birds. One of the most famous breeding stations is at the Farne Islands; another on the cliffs at Bempton; whilst less noted places are in the Isle of Wight, the Scilly Islands, and the coasts of Devon and Cornwall. The great number of local names by which the Guillemot is known round our coasts speak to its former abundance; Lavy, Marrock, Murre, Diver, and Willock—the latter applicable to the young—may be mentioned as a few of the best known. The birds congregate at their old accustomed haunts in Spring, with remarkable regularity, often punctually arriving on the same day for years in succession. At Heligoland, and certainly other places, Guillemots return to their nesting places from time to time during the winter, appearing in the morning for a little while, just as Rooks are wont to do at the nest trees. The Guillemot rears its young on the face of the lofty ocean cliffs, or on the flat tops of rock stacks. Cliffs with plenty of ledges and hollows are preferred, and in such chosen spots the birds crowd so closely that, at some stations, the wonder is how each individual can possibly find room to incubate its egg, or even secure a standing place in the general throng. There can be little doubt that in such crowded spots as the “Pinnacles,” many of the eggs never reach maturity. The Guillemot makes no nest of any kind, but lays its single large pear-shaped egg on any suitable ledge, or in any available hollow where it can be tolerably safe from toppling over into the sea. There are few more stirring sights in the bird-world than a large colony of Guillemots. I still retain the vivid impressions made upon my mind by the vast hordes of these birds at St. Kilda, at the Farne Islands, and elsewhere. Even whilst I write, I can once more see the struggling, quarrelling, rowdy hosts of Guillemots that crowd the famous “Pinnacles”; still see them pouring off in endless streams, headlong into the water, as I prepared to scale their haunt. Once more memory recalls and paints in vivid scene the beetling St. Kildan cliffs, with their rows and rows of white-breasted Guillemots, sitting tier upon tier, upwards and upwards towards the dark blue sky; my tiny boat tossing like a cork on the wild Atlantic swell, and the countless swarms of Guillemots swimming in the sea around me, hastening to the cliffs or returning from them, beaten off by more fortunate possessors of a place.
The Guillemot lays a single egg, without making a nest of any kind for its reception. If this egg be taken, however, the bird will lay a second or a third, and advantage is taken of this fact by those persons that gather them for a livelihood. The egg of no other known bird varies to such an extraordinary extent as that of the Guillemot, whilst few, if any, are more beautiful. Greens, browns, yellows, pale blues, and white, form the principal ground colour; the markings, which take the form of spots, blotches, streaks, and zones, are composed of browns, grays, and pinks, of every possible tint. One variety is white, intricately laced, netted, and streaked with pink; another is a beautiful green, streaked in the same manner with yellow, light brown, or nearly black; others of various ground colours are zoned with blotches, or marked with fantastic-shaped spots and rings. Some eggs of the Guillemot closely resemble those of the Razorbill, but may be distinguished by the yellowish-white interior of the shell when held up to the light.
There has been much controversy as to the way in which the Guillemot chicks reach the water from their lofty birthplace. Some writers assert that the parent bird carries them down to the sea on its back; on the other hand, Gätke maintains that the chicks tumble off the ledges into the water, being enticed to do so by the old birds swimming on the sea beneath the cliffs. He writes: “in its distress, the little chick tries to get as near as possible to the mother waiting for it below, and keeps tripping about on the outermost ledge of rock, often of no more than a finger’s breath, until it ends by slipping off, and, turning two or three somersaults, lands with a faint splash on the surface of the water; both parents at once take charge of it between them, and swim off with it towards the open sea. This is the only way in which I have seen this change of habitat of the young birds accomplished, during some fifty summers.” As soon as the young are sufficiently matured, the sea in the vicinity of the breeding-stations is deserted, and the colonies disperse far and wide. From this time forward, to the following breeding-season, the Guillemot’s movements are to a certain extent unknown. As Professor Newton justly asks,[4] What becomes of the millions of Guillemots and other Auks that breed in northern latitudes? The birds that are met with round the coasts of temperate Europe, and elsewhere, bear no proportion whatever to the mighty hosts whose position and movements remain unrevealed. At present the only feasible explanation seems to be that the birds, during the non-breeding-season, are scattered in quest of sustenance over many thousands of square miles of water; in summer only is their vast abundance palpable, when all are gathered into a comparatively small area.
In connection with the Guillemot mention should be made of the Ringed Guillemot, the Uria ringvia of Latham. It only differs from the Common Guillemot in having a narrow white band round the eye, which is prolonged into a streak for some distance behind and below it. It may be seen breeding in company with the commoner form, and is not known to differ in its habits. Whether it be a distinct species—as Gätke states—or merely a variety of the Common Guillemot, as many naturalists believe, still remains to be decided.
