The Penguins (Aptenodytes)
Belong exclusively to cold countries. They rarely quit the vicinity of land, yet only take to the shore in the breeding season, or when driven by squalls and storms from their favourite element. On shore they are compelled to sit erect. They carry the head very high and the neck stretched out, while their short winglets are advanced like two diminutive 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 preconcertedly met 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 neighbourhood, 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 essentially aërial, and 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 (probably the king Penguin, for he is generally the greatest thief) has robbed the nest of his neighbour, the Albatross.
Other sea-birds come to partake of the hospitality of the little republic. With the permission of the masters of the coterie they build their nests in the vacancies that occur in the squares.
The female Penguin lays but one egg, which she only abandons until hatched for a few instants, the male taking her place while she seeks her food. The Penguins are so numerous in the Antarctic seas that a hundred thousand eggs have been collected by the crew of one vessel.
The Manchots ([Fig. 82]) have been described by most of the French naturalists as a distinct species, but there is little doubt of their being only a variety of the Aptenodytes. They abound in the southern seas. Their short, stunted wings, which quite incapacitate them from 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 the Penguin, the Manchots are excellent swimmers and incomparable divers, and their coating of down is so dense that it even resists a bullet; it is consequently difficult to shoot them.
Everything about these birds indicates their adaptation to an aquatic life. Their feet are placed at the extremity of the body—an arrangement that renders them awkward and heavy when ashore; where, in short, they only come to lay and hatch their eggs. They begin to assemble in great numbers at the commencement of October. Their nests are a very simple construction; for they content themselves with digging in the sand a hole deep enough to contain two eggs—but more often one than two.
