belonging to the genus of birds known as the “vitiparr?,” there is one whose nest is formed of dried moss,[177] and is in shape so exactly like a ball, that it is impossible to discover 211 the mouth of it. the bird 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. in a spirit of foresight, they select 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,” which builds its nest with sprigs of cinnamon; the natives knock the nests 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 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.
no less shrewdness is 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 color of the plumage is pale on the inside, 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 212 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 in order that they may not be delayed in the process of incubation, as the males are apt to break the eggs. the males often fall to fighting among themselves like game-cocks, and through this very pugnacity, 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.
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 wounded or weak, then, suddenly running or flying for a short distance before him, will fall down as though she had a wing broken; 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.
