Chapter X.

1. This is the mode of the sexual intercourse of the partridge, and the way in which they are caught, and the nature of the rest of their crafty disposition. Quails, and partridges, and some other birds make their nest upon the ground, as it has been already observed. Of such birds the lark, woodcock, and quail do not perch upon trees, but upon the ground.

2. The woodpecker does not settle upon the ground, but it strikes trees in order to drive out the worms and flies which they contain, and it picks them up with its tongue as they emerge. Its tongue is wide and large. It walks upon the trees in any position, even beneath the branches, like the gecko. It has claws stronger than those of the colœus, which provide for its safety in climbing trees; for it fixes them in the bark as it walks up the trees. There is one kind of woodpecker less than the blackbird, covered with small red spots, and another kind larger than the blackbird, and a third kind nearly as large as the domestic hen. It builds its nest upon trees, as it has been already observed, both on olive and other trees; and it feeds upon ants and worms which live in trees. It hunts for worms so diligently that they say it hollows out the trees so much as to throw them down. A tame bird has been known to place an almond in a crack in wood, to prepare it for the stroke of its bill, and break it with three blows, in order to eat the kernel.
