there are some small birds which have hooked talons; the woodpecker, 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 and it immediately 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 who has given them their name.[171] one of the presages that was given by them, i cannot pass over in silence. a woodpecker came and lighted upon the head of ?lius tubero, the city pr?tor, 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 194 menaced with danger, but if killed, disaster would befall the pr?tor; in an instant he tore the bird to pieces, and before long the omen was fulfilled.[172]
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.
