Indian crows are black, like those of Europe, but much longer; their head and neck, as far as the beginning of the wings, are bald, smooth, quite destitute of feathers, but full of wrinkles. These birds subsist on the carcasses and entrails of slain beasts. Whenever oxen are killed in the open plain, as usual there, they perch upon trees or roofs of houses, presently rush down upon the intestines, and one taking each end, carry them through the air like a long rope. Their king is clothed with extremely white feathers, and though very seldom seen, flies accompanied by the other crows, as by satellites. As birds of one feather flock together, the Abipones, who live on rapine, bring up the young of these rapacious crows at home, as they become wonderfully tame: for they accompany their masters when they ride out to hunt or enjoy the country, partake their fare, and return when they return, but sometimes suffer themselves to be enticed away by flocks of crows which they meet on the road. Crows' feathers are generally chosen for arrows by the savages, on account of their strength. THE CARACARÀ, OR CARRANCHO. Kindred, and allies of the crows, are birds which the Spaniards call caracarà, or carrancho. Their body is of a yellowish grey colour, but spotted with yellow and white. They are about the size of a hen, and resemble a hawk in their head, hooked bill, eyes, long claws, and long tail. They feed upon carcasses, like crows, and do a great deal of mischief amongst hens and other birds. Their flesh is of no use. VARIOUS KINDS OF HAWKS. Caracaràs are followed by kirikirì, different kinds of hawks, spotted with various colours. Amongst them are the common hawk, the goshawk, or gerfalcon, &c. Of owls, the commonest are those which the Spaniards call lechuza, and the horned owl, which the Spaniards call mochuelo. Bats are of various kinds, and very common, as shall be shown hereafter. THE GOOSE. Water-fowl are so numerous, and of such various kinds, that it would fill a volume to describe them properly; I shall therefore only speak of some of them. I have, though very seldom, met with an immense number of geese like those of Europe in lakes. But of ducks there is such a variety and number, not only in the lakes but in the rivers also, that their dung defiles the water so as to render it unfit to be drunk. VARIOUS KINDS OF DUCKS.
