No bird is better known, on most parts of our coast, than the common gull, which is in some places called the winter-mew. Active and restless as it may seem on the wing, it has, when in repose, little that would remind us of the frequent comparison, “blithe as a bird.” We sometimes see it in gardens near the coast, with clipped wings, wandering in solitude over the paths with dejected and melancholy air, as if pining for its native sea and its companions. When free, its manners seem almost agitated as it darts eagerly on its prey, swallowing it so impetuously that it sometimes seizes the hook and bait which the fisherman has put out to take the fish, and thus wounds itself and becomes a captive. Buffon calls the clamorous and voracious gulls the vultures of the sea; they not only feed on fish, molluscous and other living animals, but seize on dead and putrid matter of every description, either floating on the waters or spread on the shore. Gulls do not dive into the water for food, but they dip now and then to seize it. They have been found by voyagers in all latitudes, and are very numerous in northern regions, where the carcases of whales and of large fish offer them an abundant store of nourishment. Hard and tough as their flesh is, yet it may be eaten; and the eggs, which are placed in large nests made of grass and sea-weeds, are very good. The gull comes to South Stack in April or May, and leaves in September. THE GUILLEMOT. Much of that loud, wild screaming which resounds among the cliffs, and which sometimes rises shrill and hoarse, even above the wildest roar of the sea, is made by some of those birds which look like the diver, and which can also both swim and dive exceedingly well. The common guillemot is commonly called the foolish guillemot, or foolish Willie, or wild Willie; though why it should be deemed inferior to other sea-birds in sense is not very apparent, as it seems to surpass many of them in this respect. It may be that when on shore the bird has an awkward appearance, as the legs are placed so far back beneath the body that they walk badly, and their wings are so short and narrow that they can scarcely flutter. Let our bird, however, but get upon the face of the waters, and we shall see it swim with grace and ease, while the very position of its legs, which renders it a bad walker, is suited to facilitate its diving. It dives very low, and the wings aid its progress as it rises to the surface when some tempting fish, or marine insect, induces it to urge onwards with great rapidity. It is by means of these short wings, too, that the guillemots clear the projecting ledges of rocks and cliffs, and jump from point to point, till they reach those high, and to us inaccessible, spots where they often build. Its single egg is placed on the bare rock. The guillemot visits South Stack about the month of April, and by the month of September, both old and young,
