This is one of our common sea-birds during a great portion of the year, though little known to ordinary sea-side visitors, owing to its habit of keeping well out to sea and having nothing ostentatious in its habits. Yet, during a cruise in a yacht, on almost any part of the coast, a practised eye will often discover a few stragglers, distinguished among other sea-birds by their black and white colours, short neck, and sharp beak. They swim low in the water; and when disturbed do not invariably dive like the Grebes and Divers, but readily take wing. They are essentially marine birds, never resorting to fresh water, and living exclusively on fish, which they capture by diving, an art in which they are scarcely less skilful than the true Divers, and which they practise in the same way—by the means, namely, of both wings and feet. Occasionally, a small party may be observed, flying in single file near the surface of the water. On the eastern coast of England, the Guillemot is best known by the name of Willock. It is also called Tinker's Hue, or, as Yarrell gives it, 'Tinkershere'; and in the west of England it is often called a Murr. The old writers describe it under the name of Greenland Dove, or Sea Turtle-Dove; and in Scotland it has a variety of other names. Tinker's Hue is, I presume, the sobriquet of a white bird with a smutty back; Murr is clearly a corruption of Mergus, or 'diver'. Yet more commonly it is known as the 'Foolish Guillemot', a term of reproach analogous to that of 'Booby', given to it from the indifference which it evinces, in the breeding season, to one of its few, but that one the most formidable of its enemies, man. Early in spring Guillemots throng together from all parts of the open sea, and repair to some lofty cliff, where, on a narrow ledge of rock, which in their folly they deem inaccessible, they lay each a single egg. As the bird holds the egg between her legs, she could not well cover more than one; and though a concave nest is very needful to keep eggs together when there are several, no such contrivance is necessary when there is one only; so the Foolish Guillemot builds no nest, but lays a solitary egg on the bare rock. The egg, which is large, is thick-shelled and rough, so that it receives no detriment from the rock; and it is not likely to roll off, for at one end it is thick, and at the other tapers almost to a point; consequently, if accidentally moved by the parent bird when taking flight, it turns as if on a pivot, but does not fall off. At this season, the cliffs to which Guillemots resort are frequented also by myriads of other sea-birds, such as Razor-bills, Puffins, and Gulls, each congregating with its own species, but never consorting with another. In Iceland, the Faroe Islands, St. Kilda, the Orkneys, and many parts of the coast of Scotland, the breeding season of these birds is the harvest-time of the natives. Either by climbing from below, or by being let down with ropes from above, the egg-collectors invade the dominions of these literally feathered 'tribes'. The Foolish Guillemots, rather than leave their charge, suffer themselves to be knocked on the head, to be netted, or noosed. Although stationed so close to each other that a Foolish Guillemot alone could know its own egg, they learn no wisdom from the fate of their nearest neighbours. They are captured in detail for the sake of their feathers; and their eggs are taken for food. In St. Kilda and, perhaps, elsewhere, young birds are also taken in large numbers, and salted for consumption in winter. Such as escape this systematic slaughter flounder, as well as they are able, into the sea when nearly fledged, or are carried thither by their foolish mothers. There they learn to swim, to dive, and to fish, and about the middle of August old and young disperse.

Huge baskets of their eggs are sometimes brought to the markets of seaport towns (I have seen them so far south as Devonport), and sold for a price exceeding that of domestic fowls, for they are much larger, and are said to afford good eating. Wilson, in his Voyage round the Coasts of Scotland, says that the natives of St. Kilda prefer the eggs of these, and other sea-fowl, 'when sour; that is, when about ten or twelve days old, and just as the incipient bird, when boiled, forms in the centre into a thickish flaky matter, like milk.'[55] Great quantities are used in the neighbourhood of Flamborough Head early in the nesting season.

THE BLACK GUILLEMOT
ÚRIA GRYLLE

Upper plumage black; middle of the wings and under parts white; iris brown; feet red. Length thirteen and a half inches. Eggs whitish grey, blotched and speckled with grey and two shades of brown.

The Black Guillemot, is a resident species breeding on the Isle of Man, and on the Irish coasts. In Scotland it is common. Its mode of life, as described by Macgillivray, who was familiarly acquainted with it, differs in no material respect from that of the species already described. It is, however, much smaller, and lays two or sometimes three eggs. Macgillivray says that, on those parts of the coast which it frequents, attempts are often made to rear it in captivity; but always unsuccessfully. In summer, these birds may be readily distinguished from other sea-fowl, by their black and white plumage and red feet: the predominant tint of the plumage in winter is white, with a tinge of grey; and in high latitudes the proportion of white increases.

THE LITTLE AUK
MÉRGULUS ÁLLE

Head and upper parts black; two bands across the wings; a spot above the eye and all the under parts white. In summer the throat and front of the neck are also black. Length about seven inches. Eggs uniform pale blue.

The Little Auk is essentially a northern sea-bird, coming to us in winter, and is described by Arctic voyagers under the name of Rotche. It is an indefatigable swimmer, and has considerable powers of flight; but it does not possess the faculty of diving to the same degree as the Divers and Grebes, as it generally stays but a short time under water. Hence it must find its food near the surface; and this is supposed to consist of the small crustaceous animals which are so abundant in the Arctic waters. Little Auks are eminently social birds, and have been observed occasionally in such numbers on the water and floating masses of ice as almost to hide their resting-place. They rarely travel far south; and when they visit our shores, which is in winter, and after tempestuous weather, they are supposed to have been driven hither against their will. Instances are recorded of specimens having been found far inland, disabled or dead. It lays only a single egg.
