Æthiopia and India, more especially, produce birds of diversified plumage, and such as quite surpass all description. In the front rank of these is the phœnix,[165] that famous bird of Arabia; though I am not quite sure that its existence is not all a fable. It is said that there is only one in existence in the whole world, and that that one has not been seen very often. We are told that this bird is of the size of an eagle, and has a brilliant golden plumage around the neck, while the rest of the body is of a purple color; except the tail, which is azure, with long feathers intermingled of a roseate hue; the throat is adorned with a crest, and the head with a tuft of feathers. The first Roman who described this bird, and who has done so with the greatest exactness, was the senator Manilius, so famous for his learning, which he owed to the instructions of no teacher. He tells us that no person has ever seen this bird eat, that in Arabia it is looked upon as sacred to the sun, that it lives five hundred and forty years, that when it becomes old it builds a nest of cassia and sprigs of incense, which it fills with perfumes, and then lays its body down upon them to die; that from its bones and marrow there springs at first a sort of small worm, which in time changes into a little bird: that the first thing that it does is to perform the obsequies of its predecessor, and to carry the nest entire to the city of the Sun near Panchaia, and there deposit it upon the altar of that divinity.
The same Manilius states also, that the revolution of the great year[166] is completed with the life of this bird, and that then a new cycle comes round again with the same characteristics as the former one, in the seasons and the appearance of the stars; and he says that this begins about mid-day of the day on which the sun enters the sign of Aries. He also tells us that when he wrote to the above effect, in the consulship of Licinius and Cornelius, it was the two hundred and fifteenth year of the said revolution. Cornelius Valerianus says that the phœnix took its flight from Arabia into Egypt in the consulship of Plautius and Papinius. This bird was brought to Rome in the censorship of the Emperor Claudius, being the eight hundredth year from the building of the City, and it was exposed to public view in the Comitium. This fact is attested by the public Annals, but there is no one who supposes that it was a genuine phœnix.
CHAPTER III.
THE EAGLE.
Of all the birds with which we are acquainted, the eagle is looked upon as the most noble, and the most remarkable for its strength. There are six different kinds; the one called “melanaetos” or black eagle by the Greeks, and “valeria” in our language, the least in size of them all, but the most remarkable for its strength, is of a blackish color. It is the only one among all the eagles that feeds its young; for the others, as we shall presently mention, drive them away; it is the only one too that has neither cry nor murmur; it is an inhabitant of the mountains. The second kind is the pygargus (white tail), an inhabitant of the cities and plains, and distinguished by the whiteness of its tail. The third is the morphnos; it is the second in size and strength, and dwells in the vicinity of lakes. Phemonoë, who was styled the “daughter of Apollo,” has stated that this eagle has teeth, but that it has neither voice nor tongue; she says also that it is the blackest of all the eagles, and has a longer tail than the rest; Bœus is of the same opinion. This eagle has the instinct to break the shell of the tortoise by letting it fall from aloft, a circumstance which caused the death of the poet Æschylus. An oracle, it is said, had predicted his death on that day by the fall of a house, upon which he took the precaution of trusting himself only under the canopy of the heavens.
BALD, OR WHITE-HEADED EAGLE.—Haliaëtus Leucocephalus.
The fourth kind of eagle is the “percnopterus” (black wing), with much the appearance of the vulture, having remarkably small wings, while the rest of the body is larger than the others; but it is of a timid and degenerate nature, so that even a raven can beat it. It is always famishing and ravenous, and has a plaintive, murmuring cry. It is the only one among the eagles that will carry off the dead carcass; the others settle on the spot where they have killed their prey. The character of this species causes the fifth one to be known by the distinctive name of “gnesios,” as being the genuine eagle, and the only one of untainted lineage; it is of moderate size, of rather reddish color, and rarely to be met with. The haliætus or sea-eagle is the last, and is remarkable for its bright and piercing eye. It poises itself aloft, and the moment it catches sight of a fish in the sea below, pounces headlong upon it, and cleaving the water with its breast, carries off its prey.
The eagle which we have mentioned as forming the third species, pursues the aquatic birds in the vicinity of standing waters: in order to make their escape they plunge into the water every now and then, until at length they are overtaken by lassitude and sleep, upon which the eagle immediately seizes them. The contest that takes place is really a sight worthy to be seen. The bird makes for the shore to seek a refuge, especially if there should happen to be a bed of reeds there; while in the mean time the eagle endeavors to drive it away with repeated blows of its wings, and tumbles into the water in its attempts to seize it. While it is standing on the shore its shadow is seen by the bird, which immediately dives beneath, and then making its way in an opposite direction, emerges at some point at which it thinks it is the least likely to be looked for. This is the reason why these birds swim in flocks, for when in large numbers they are in no danger from the enemy; as by dashing up the spray with their wings they blind him.
Again, it often happens that the eagle is not able to carry the bird aloft on account of its weight, and in consequence they both of them sink together. This and the haliætus beat their young ones while in an unfledged state, with their wings, and force them from time to time to look steadily upon the rays of the sun; and if the parent sees either of them wink, or even its eye water, it throws it headlong out of the nest, as being spurious and degenerate, but rears the one whose gaze remains fixed and steady.
Eagles build among rocks and trees; they lay three eggs, and generally hatch but two young ones, though occasionally as many as three have been seen. Being weary of the trouble of rearing both, they drive one of them from the nest: for just at this time the providential foresight of Nature has denied them a sufficiency of food, to save the young of all other animals from becoming their prey. During this period, their talons become reversed, and their feathers grow white from continued hunger, so that it is not to be wondered at that they take a dislike to their young. The ossifrage, however, a kindred species, takes charge of the young ones thus rejected, and rears them with its own; but the parent bird still pursues them with hostility, even when grown up, and drives them away, as being its rivals in rapine. Under any circumstances, one pair of eagles requires a very considerable space of ground to forage over, in order to find sufficient sustenance; for which reason they mark out by boundaries their respective allotments. They do not immediately carry off their prey, but first deposit it on the ground, test its weight and then fly away with it.
