THE FAMILY OF DIVERS.
The most important birds found in this family are the Great Northern Diver, the Arctic Diver, Penguins, Auks, Grebes, and Guillemots.
All these Birds are distinguished by wings so thin and short as to be almost useless for flying. They are all habitual divers and tireless swimmers, using their wings as Fish do their fins. To raise their wings after taking a down stroke requires much greater effort than a Bird of flight makes in raising its wings in the air; for this reason the muscle in the wings of the Diving Birds has an unusually large development to give them greater strength.
The Divers are inhabitants of northern seas. There they build their nests on some solitary island and lay two eggs, oblong in shape and white in color. Fish, particularly the Herring, are their principal food, and they are such active swimmers and divers that it takes a quick eye and hand to shoot them.
THE GREAT NORTHERN DIVER.
This great Bird has been called a wanderer on the ocean. It is not only found along the margins of the sea, fishing in the bays and at the river banks, but is also met with out on the ocean many miles from the shore. Narrow channels and sandy bays are, however, its favorite resorts; there it floats, its body deeply submerged in the water. But though swimming so deep in the water, it can overtake and shoot ahead of all the more buoyant swimmers.
The Bird is sometimes known as the Loon. It is seldom found on the land, being ill fitted for walking or flying, and although it is expert in swimming long distances under water, and when it does come up seldom exposes more than its neck, it flies rather better than many other short-winged divers. It flies heavily, in a circle, round those who have disturbed it in its haunts, its loud and melancholy cry resembling the howling of a wolf, or the distant scream of a man in distress. When the “Loon” calls frequently, it is supposed to portend a storm. In the bad weather which precedes the advent of winter on the northern American lakes, previous to migration, the wild weird note of the Loon is so unnatural that the Indians ascribe to it supernatural powers.
THE PENGUINS.
PENGUIN.
The Penguins belong exclusively to cold countries. They live almost entirely in the water, and although they seldom come ashore, except to build their nests and lay their eggs, or when driven by squalls or storms from their favorite element, they do not often swim far from the land. On the shore they are compelled to sit erect, as their feet are placed at the extremity of the body—an arrangement which renders them awkward and heavy when they try to sit or walk. They carry the head very high and the neck stretched out, while their short winglets are held out like two short arms. When they sit perched in flocks on some lofty projecting rock they might be mistaken at a distance for a line of soldiers.
At certain periods of the year the Penguins assemble on the beach as if they had planned to meet for deliberation. These assemblies last for a day or two, and are conducted with an obvious degree of solemnity. When the meeting results in a decision, they proceed to work with great activity.
Upon a ledge of rock, sufficiently level and of the necessary size, they trace a square with one of its sides parallel and overlooking the edge of the water, which is left open for the egress of the colony. Then with their beaks they proceed to collect all the stones in the neighborhood, which they heap up outside the lines marked out, to serve them as a wall to shelter them from the prevailing winds. During the night these openings are guarded by sentinels.
They afterwards divide the enclosure into smaller squares, each large enough to receive a certain number of nests, with a passage between each square. No architect could arrange the plan in a more regular manner.
What is most singular is that the Albatross, a Bird adapted for flight, associates at this period with these half Fish, half Birds, the Penguins; so that the nest of an Albatross may be seen next the nest of a Penguin, and the whole colony, so differently constituted, appear to live on the best terms of intimacy. Each keeps to its own nest, and if by chance there is a complaint, it is that some Penguin has robbed the nest of his neighbor, the Albatross.
Other Sea-birds come to partake of the hospitality of the little republic. With the permission of the masters of the society, they build their nests in the vacancies that occur in the squares.
The Penguin lays but one egg, which she only leaves for a few moments until hatched, the mate taking her place while she seeks her food. The Penguins are so numerous in the Antarctic seas, that 100,000 eggs have been collected by the crew of one vessel.
The King Penguin has been described by most Naturalists as a distinct species. Of this there is little doubt. They abound in the southern seas. Their short stunted wings, which make them quite incapable of flying, are reduced to a flat and very short stump, totally destitute of feathers, being covered with a soft down, having something of the appearance of hair, which might be taken for scales. Like all the Penguins, this Bird is an excellent swimmer and diver, and its coating of down is so dense that it even resist a bullet; it is consequently difficult to shoot.
Their nests are a very simple construction, for they content themselves with a hole in the sand deep enough to contain two eggs, but more often one.
In spite of the limited number of eggs, the quantity of these Birds found in the south of Patagonia is something marvellous. When sailors land in these high latitudes they take or kill as many as they choose. Sir John Narborough says, speaking of those at the Falkland Islands, that “when the sailors walked among the feathered population to provide themselves with eggs, they were regarded with sidelong glances.” In many places the shores were covered with these Birds, and 300 have been taken within an hour; for generally they make no effort to escape, but stand quietly by while their companions are being knocked down with sticks.
In another islet, in the Straits of Magellan, Captain Drake’s crew killed more than 3,000 in one day. These facts are not exaggerated. This island, when visited by these navigators, probably had never been pressed previously by a human foot, and the Birds had succeeded each other from generation to generation in incalculable numbers, hitherto free from molestation.
The Penguins have no fear of man. Mr. Darwin pleasantly relates an encounter that he had with one of these Birds on the Falkland Islands. “One day,” he says, “having placed myself between a Penguin and the water, I was much amused by the action of the Bird. It was a brave Bird, and, till reaching the sea, it regularly fought and drove me backwards. Nothing less than heavy blows would have stopped him. Every inch gained he kept firmly, standing close before me firm, erect and determined, all the time rolling his head from side to side in a very odd manner.”
There are many species of Penguins, the handsomest probably being the Crested Penguin, which is a native of Patagonia, and has a very conspicuous appearance. These Birds are called by sailors, regardless of species, Jackass Penguins, from their habit, when on shore, of throwing their head backwards, and of making a strange loud noise very like the braying of a Donkey.
This family all defend themselves vigorously with their beaks when an attempt is made to lay hands on them; and when pursued, they will pretend to retreat, and return immediately, throwing themselves upon their assailant. “At other times they will look at you askance,” says Pernetty, “the head inclined first on one side, then on the other, as if they were mocking you.” They hold themselves upright on their feet, the body erect in a perpendicular line with the head. Navigators passing these islands of the southern seas might suppose that they were densely inhabited, for the loud roaring voices of these Birds produce a noise equal to that of a great crowd. The flesh is most unpalatable, but it is frequently the only resource of ship’s crews who find themselves short of provisions in these inhospitable regions. However, their eggs have the redeeming quality of being excellent.
THE AUK.
The Auk is a noble Bird, which was once common in our waters, but at this date scarce even in the Arctic seas; it is but little known. In habits and mode of life it strongly resembles the Penguins.
THE GREBES.
The Grebes have the head small, the neck somewhat elongated, the legs attached to the abdomen, the tail rudimentary, the tarsi compressed, the anterior toes united at their base by a membrane. These Birds live on the sea, but they inhabit fresh water by preference, feeding on small Fishes, Worms, Molluscs, Insects, and the products of aquatic vegetation. While they dive and swim admirably, they also fly with vigorous wing; but they rarely resort to this unless alarmed or when migrating.
The nest of the Grebe is usually placed in a tuft of rushes on the edge of the water. It is composed of large grassy plants roughly interlaced, and the interior is lined with soft broken grasses delicately arranged. The eggs vary from three to seven. On shore they cannot walk well, but creep along in an awkward manner. They are covered with fine, warm down, so close and lustrous that muffs are made from their breast.
Grebes are inhabitants of the old and new Continents. Among the European species may be noticed the Crested Grebe, about the size of a Duck, ornamented with a double black crest; the Horned Grebe, provided with two long tufts of feathers, in the form of a horn; and the Eared Grebe, distinguished by its beak, the base of which is depressed, while the point is raised upwards.
The Crested Grebe is the best known in the United States. These have been found in limited numbers around the Great Lakes and as far south as Mexico.
