THE NIGHTINGALE.
The song of the nightingale is to be heard, without intermission, for fifteen days and nights, continuously, when the foliage is thickening, as it bursts from the bud; a bird which deserves our admiration in no slight degree. First of all, what a powerful voice in so small a body! its note, how long, and how well sustained! And then, too, it is the only bird the notes of which are modulated in accordance with the strict rules of musical science. At one moment, as it sustains its breath, it will prolong its note, and then at another, will vary it with different inflexions; then, again, it will break into distinct chirrups, or pour forth an endless series of roulades. Then it will warble to itself, while taking breath, or else disguise its voice in an instant; while sometimes, again, it will twitter to itself, now with a full note, now with a grave, now again sharp, now with a broken note, and now with a prolonged one. Sometimes, again, when it thinks fit, it will break out into quavers, and will run through, in succession, alto, tenor, and bass: in a word, in so tiny a throat is to be found all the melody that the ingenuity of man has ever discovered through the medium of the invention of the most exquisite flute: so much so, that there can be no doubt it was an infallible presage of his future sweetness as a poet, when one of these creatures perched and sang on the infant lips of the poet Stesichorus.
That there may remain no doubt that there is a certain degree of art in its performances, we may here remark that every bird has a number of notes peculiar to itself; for they do not, all of them, have the same, but each, certain melodies of its own. They vie with one another, and the spirit with which they contend is evident to all. The one that is vanquished, often dies in the contest, and will rather yield its life than its song. The younger birds are listening in the meantime, and receive the lesson in song from which they are to profit. The learner hearkens with the greatest attention, and repeats what it has heard, and then they are silent by turns; this is understood to be the correction of an error on the part of the scholar, and a sort of reproof, as it were, on the part of the teacher. Hence it is that nightingales fetch as high a price as slaves, and, indeed, sometimes more than used formerly to be paid for a man in a suit of armour.
I know that on one occasion six thousand sesterces were paid for a nightingale, a white one it is true, a thing that is hardly ever to be seen, to be made a present of to Agrippina, the wife of the Emperor Claudius. A nightingale has been often seen that will sing at command, and take alternate parts with the music that accompanies it; men, too, have been found who could imitate its note with such exactness, that it would be impossible to tell the difference, by merely putting water in a reed held crosswise, and then blowing into it, a languette being first inserted, for the purpose of breaking the sound and rendering it more shrill. But these modulations, so clever and so artistic, begin gradually to cease at the end of the fifteen days; not that you can say, however, that the bird is either fatigued or tired of singing; but, as the heat increases, its voice becomes altogether changed, and possesses no longer either modulation or variety of note. Its colour, too, becomes changed, and at last, throughout the winter, it totally disappears. The tongue of the nightingale is not pointed at the tip, as in other birds. It lays at the beginning of the spring, six eggs at the most.

THE MELANCORYPHUS, THE ERITHACITS, AND THE PHŒNICURUS.
The change is different that takes place in the ficedula, for this bird changes its shape as well as its colour. “Ficedula” is the name by which it is called in autumn, but not after that period; for then it is called “melancoryphus.” In the same manner, too, the erithacus of the winter is the “phœnicurus” of the summer. The hoopoe also, according to the poet Æschylus, changes its form; it is a bird that feeds upon filth of all kinds, and is remarkable for its twisted topknot, which it can contract or elevate at pleasure along the top of the head.

THE ŒNANTHE, THE CHLORION, THE BLACKBIRD, AND THE IBIS.
The cenanthe, too, is a bird that has stated days for its re- treat. At the rising of Sirius it conceals itself, and at the setting of that star comes forth from its retreat: and this it does, a most singular thing, exactly upon both those days. The chlorion, also, the body of which is yellow all over, is not seen in the winter, but comes out about the summer solstice.
(30.) The blackbird is found in the vicinity of Cyllene, in Arcadia, with white plumage; a thing that is the case nowhere else. The ibis, in the neighbourhood of Pelusium only is black, while in all other places it is white.

THE TIMES OF INCUBATION OF BIRDS.
The birds that have a note, with the exception of those previously mentioned, do not by any chance produce their young before the vernal or after the autumnal equinox. As to the broods produced before the summer solstice, it is very doubtful if they will survive, but those hatched after it thrive well.

THE HALCYONES: THE HALCYON DAYS THAT ARE FAVOURABLE TO NAVIGATION.
It is for this that the halcyon is more especially remarkable; the seas, and all those who sail upon their surface, well know the days of its incubation. This bird is a little larger than a sparrow, and the greater part of its body is of an azure blue colour, with only an intermixture of white and purple in some of the larger feathers, while the neck is long and slender. There is one kind that is remarkable for its larger size and its note; the smaller ones are heard singing in the reed-beds. It is a thing of very rare occurrence to see a halcyon, and then it is only about the time of the setting of the Vergiliæ, and the summer and winter solstices; when one is sometimes to be seen to hover about a ship, and then immediately disappear. They hatch their young at the time of the winter solstice, from which circumstance those days are known as the “ halcyon days:” during this period the sea is calm and navigable, the Sicilian sea in particular. They make their nest during the seven days before the winter solstice, and sit the same number of days after. Their nests are truly wonderful; they are of the shape of a ball slightly elongated, have a very narrow mouth, and bear a strong resemblance to a large sponge. It is impossible to cut them asunder with iron, and they are only to be broken with a strong blow, upon which they separate, just like foam of the sea when dried up. It has never yet been discovered of what material they are made; some persons think that they are formed of sharp fish-Bones, as it is on fish that these birds live. They enter rivers also; their eggs are five in number.

OTHER KINDS OF AQUATIC BIRDS.
The sea-mew also builds its nest in rocks, and the diver in trees as well. These birds produce three at the very most; the sea-mew in summer, the diver at the beginning of spring.

THE INSTINCTIVE CLEVERNESS DISPLAYED BY BIRDS IN THE CONSTRUCTION OF THEIR NESTS. THE WONDER- FUL WORKS OF THE SWALLOW. THE BANK-SWALLOW.
The form of the nest built by the halcyon reminds me also of the instinctive cleverness displayed by other birds; and, indeed, in no respect is the ingenuity of birds more deserving of our admiration. The swallow builds its nest of mud, and strengthens it with straws. If mud happens to fail, it soaks itself with a quantity of water, which it then shakes from off its feathers into the dust. It lines the inside of the nest with soft feathers and wool, to keep the eggs warm, and in order that the nest may not be hard and rough to its young when hatched. It divides the food among its offspring with the most rigid justice, giving it first to one and then to another. With a remarkable notion of cleanliness, it throws out of the nest the ordure of the young ones, and when they have grown a little older, teaches them how to turn round, and let it fall outside of the nest.
&
nbsp; There is another kind of swallow, also, that frequents the fields and the country; its nest is of a different shape, though of the same materials, but it rarely builds it against houses. The nest has its mouth turned straight upwards, and the entrance to it is long and narrow, while the body is very capacious. It is quite wonderful what skill is displayed in the formation of it, for the purpose of concealing the young ones, and of presenting a soft surface for them to lie upon. At the Heracleotic Mouth of the Nile in Egypt, the swallows present an insuperable obstacle to the inroads of that river, in the embankment which is formed by their nests in one continuous line, nearly a stadium in length; a thing that could not possibly have been effected by the agency of man. In Egypt, too, near the city of Coptos, there is an island sacred to Isis. In the early days of spring, the swallows strengthen the angular corner of this island with chaff and straw, thus fortifying it in order that the river may not sweep it away. This work they persevere in for three days and nights together, with such unremitting labour, that it is a well-known fact that many of them die with their exertions. This, too, is a toil which recurs regularly for them every year.
There is, again, a third kind of swallow, which makes holes in the banks of rivers, to serve for its nest. The young of these birds, reduced to ashes, are a good specific against mortal maladies of the throat, and tend to cure many other diseases of the human body. These birds do not build nests, and they take care to migrate a good many days before, if it so happens that the rise of the river is about to reach their holes.

THE ACANTHYLLIS AND OTHER BIRDS.
Belonging to the genus of birds known as the “ vitiparræ,” there is one whose nest is formed of dried moss, and is in shape so exactly like a ball, that it is impossible to discover the mouth of it. The bird, also, that is known as the acanthyllis, makes its nest of a similar shape, and interweaves it with pieces of flax. The nest of one of the woodpeckers, very much like a cup in shape, is suspended by a twig from the end of the branch of a tree, so that no quadruped may be able to reach it. It is strongly asserted, that the witwall sleeps suspended by its feet, because it fancies that by doing so it is in greater safety. A thing, indeed, that is well-known of them all, is the fact that, in a spirit of foresight, they select the projecting branches of trees that are sufficiently strong, for the purpose of supporting their nests, and then arch them over to protect them from the rain, or else shield them by means of the thickness of the foliage.
In Arabia there is a bird known as the “cinnamolgus.” It builds its nest with sprigs of cinnamon; and the natives knock them down with arrows loaded with lead, in order to sell them. In Scythia there is a bird, the size of the otis, which produces two young ones always, in a hare’s skin suspended from the top branches of a tree. Pies, when they have observed a person steadily gazing at their nest, will immediately remove their eggs to another place. This is said to be accomplished in a truly wonderful manner, by such birds as have not toes adapted for holding and removing their eggs. They lay a twig upon two eggs, and then solder them to it by means of a glutinous matter secreted from their body; after which, they pass their neck between the eggs, and so forming an equipoise, convey them to another place.

THE MEROPS — PARTRIDGES.
No less, too, is the shrewdness displayed by those birds which make their nests upon the ground, because, from the extreme weight of their body, they are unable to fly aloft. There is a bird, known as the “merops,” which feeds its parents in their retreat: the colour of the plumage on the inside is pale, and azure without, while it is of a somewhat reddish hue at the extremity of the wings: this bird builds its nest in a hole which it digs to the depth of six feet.
Partridges fortify their retreat so well with thorns and shrubs, that it is effectually protected against beasts of prey. They make a soft bed for their eggs by burying them in the dust, but do not hatch them where they are laid: that no suspicion may arise from the fact of their being seen repeatedly about the same spot, they carry them away to some other place. The females also conceal themselves from their mates, in order that they may not be delayed in the process of incubation, as the males, in consequence of the warmth of their passions, are apt to break the eggs. The males, thus deprived of the females, fall to fighting among themselves; and it is said that the one that is conquered, is treated as a female by the other. Trogus Pompeius tells us that quails and dunghill cocks sometimes do the same; and adds, that wild partridges, when newly caught, or when beaten by the others, are trodden promiscuously by the tame ones. Through the very pugnacity thus inspired by the strength of their passions, these birds are often taken, as the leader of the whole covey frequently advances to fight with the decoy-Bird of the fowler; as soon as he is taken, another and then another will advance, all of which are caught in their turn. The females, again, are caught about the pairing season; for then they will come forward to quarrel with the female decoy-Bird of the fowler, and so drive her away. Indeed, in no other animal is there any such susceptibility in the sexual feelings; if the female only stands opposite to the male, while the wind is blowing from that direction, she will become impregnated; and during this time she is in a state of the greatest excitement, the beak being wide open and the tongue thrust out. The female will conceive also from the action of the air, as the male flies above her, and very often from only hearing his voice: indeed, to such a degree does passion get the better of her affection for her offspring, that although at the moment she is sitting furtively and in concealment, she will, if she perceives the female decoy-Bird of the fowler approaching her mate, call him back, and summon him away from the other, and voluntarily submit to his advances.
Indeed, these birds are often carried away by such frantic madness, that they will settle, being quite blinded by fear, upon the very head of the fowler. If he happens to move in the direction of the nest, the female bird that is sitting will run and throw herself before his feet, pretending to be over-heavy, or else weak in the loins, and then, suddenly running or flying for a short distance before him, will fall down as though she had a wing broken, or else her feet; just as he is about to catch her, she will then take another fly, and so keep baffling him in his hopes, until she has led him to a considerable distance from her nest. As soon as she is rid of her fears, and free from all maternal disquietude, she will throw herself on her back in some furrow, and seizing a clod of earth with her claws, cover herself all over. It is supposed that the life of the partridge extends to sixteen years.

PIGEONS.
Next to the partridge, it is in the pigeon that similar tendencies are to be seen in the same respect: but then, chastity is especially observed by it, and promiscuous intercourse is a thing quite unknown. Although inhabiting a domicile in common with others, they will none of them violate the laws of conjugal fidelity: not one will desert its nest, unless it is either widower or widow. Although, too, the males are very imperious, and sometimes even extremely exacting, the females put up with it: for in fact, the males sometimes suspect them of infidelity, though by nature they are incapable of it. On such occasions the throat of the male seems quite choked with indignation, and he inflicts severe blows with the beak: and then afterwards, to make some atonement, he falls to billing, and by way of pressing his amorous solicitations, sidles round and round the female with his feet. They both of them manifest an equal degree of affection for their offspring; in- deed, it is not unfrequently that this is a ground for correction, in consequence of the female being too slow in going to her young. When the female is sitting, the male renders her every attention that can in any way tend to her solace and comfort. The first thing that they do is to eject from the throat some saltish earth, which they have digested, into the mouths of the young ones, in order to prepare them in due time to receive their nutriment. It is a pe
culiarity of the pigeon and of the turtle-dove, not to throw back the neck when drinking, but to take in the water at a long draught, just as beasts of burden do.
(35.) We read in some authors that the ring-dove lives so long as thirty years, and sometimes as much as forty, without any other inconvenience than the extreme length of the claws, which with them, in fact, is the chief mark of old age; they can be cut, however, without any danger. The voice of all these birds is similar, being composed of three notes, and then a mournful noise at the end. In winter they are silent, and they only recover their voice in the spring. Nigidius expresses it as his opinion that the ring-dove will abandon the place, if she hears her name mentioned under the roof where she is sitting on her eggs: they hatch their young just after the summer solstice. Pigeons and turtle-doves live eight years.
(36.) The sparrow, on the other hand, which has an equal degree of salaciousness, is short-lived in the extreme. It is said that the male does not live beyond a year; and as a ground for this belief, it is stated that at the beginning of spring, the black marks are never to be seen upon the beak which began to appear in the summer. The females, however, are said to live somewhat longer.
