CHAP. 20. (18.)—THE WOOD-PECKER OF MARS.
There are some small birds also, which have hooked talons; the wood-pecker, for example, surnamed “of Mars,” of considerable importance in the auspices. To this kind belong the birds which make holes in trees, and climb stealthily up them, like cats; mounting with the head upwards, they tap against the bark, and learn by the sound whether or not their food lies beneath; they are the only birds that hatch their young in the hollows of trees. It is a common belief, that if a shepherd drives a wedge into their holes, they apply a certain kind of herb,[2944] immediately upon which it falls out. Trebius informs us that if a nail or wedge is driven with ever so much force into a tree in which these birds have made their nest, it will instantly fly out, the tree making a loud cracking noise the moment that the bird has lighted upon the nail or wedge.
These birds have held the first rank in auguries, in Latium, since the time of the king[2945] who has given them their name. One of the presages that was given by them, I cannot pass over in silence. A woodpecker came and lighted upon the head of Ælius Tubero, the City prætor, when sitting on his tribunal dispensing justice in the Forum, and showed such tameness as to allow itself to be taken with the hand; upon which the augurs declared that if it was let go, the state was menaced with danger, but if killed, disaster would befall the prætor; in an instant he tore the bird to pieces, and before long the omen was fulfilled.[2946]
CHAP. 21. (19.)—BIRDS WHICH HAVE HOOKED TALONS.
Many birds of this kind feed also on acorns and fruit, but only those which are not carnivorous, with the exception of the kite; though when it feeds on anything but flesh, it is a bird of ill omen.
The birds which have hooked talons are never gregarious; each one seeks its prey by itself. They nearly all of them soar to a great height, with the exception of the birds of the night, and more especially those of larger size. They all have large wings, and a small body; they walk with difficulty, and rarely settle upon stones, being prevented from doing so by the curved shape of their talons.
CHAP. 22. (20.)—THE PEACOCK.
We shall now speak of the second class of birds, which is divided into two kinds; those which give omens[2947] by their note, and those which afford presages by their flight. The variation of the note in the one, and the relative size in the other, constitute the differences between them. These last, therefore, shall be treated of first, and the peacock shall have precedence of all the rest, as much for its singular beauty as its superior instinct, and the vanity it displays.
When it hears itself praised, this bird spreads out its gorgeous colours, and especially if the sun happens to be shining at the time, because then they are seen in all their radiance, and to better advantage. At the same time, spreading out its tail in the form of a shell, it throws the reflection upon the other feathers, which shine all the more brilliantly when a shadow is cast upon them; then at another moment it will contract all the eyes[2948] depicted upon its feathers in a single mass, manifesting great delight in having them admired by the spectator. The peacock loses its tail every year at the fall of the leaf, and a new one shoots forth in its place at the flower season; between these periods the bird is abashed and moping, and seeks retired spots. The peacock lives twenty-five years, and begins to show its colours in the third. By some authors it is stated that this bird is not only a vain creature, but of a spiteful disposition also, just in the same way that they attribute bashfulness to the goose.[2949] The characteristics, however, which they have thus ascribed to these birds, appear to me to be utterly unfounded.
