This facetious personage has in his pleasantry the advantage due to the seriousness, gravity, and sadness of his demeanour. I saw one daily, in the streets of Nantes, on the threshold of an alley, which, in his demi-captivity, could only console himself for his clipped wings by playing tricks with the dogs. He suffered the curs to pass unmolested; but when his malicious eye espied a dog of handsome figure, worthy indeed of his courage, he hopped behind him, and, by a skilful and unperceived manœuvre, leapt upon his back, gave him, hot and dry, two stabs with his strong black beak: the dog fled, howling. Satisfied, tranquil, and serious, the crow returned to his post, and one could never have supposed that so grim-looking a fellow had just indulged in such an escapade.
It is said that in a state of freedom, strong in their spirit of association, and in their numbers, they hazard the most audacious games, even to watching the absence of the eagle, stealing into his redoubtable nest, and robbing it of the eggs. And, what is more difficult to believe, naturalists pretend to have seen great troops of them, which, when the eagle is at home, and defending his family, deafen him with their cries, defy him, entice him forth, and contrive, though not without a battle, to carry off an eaglet.
Such exertions and such danger for this miserable prey! If the thing be true, we must suppose that the prudent republic, frequently troubled or harassed by the tyrant of the country, decrees the extinction of his race, and believes itself bound by a great act of devotion, cost what it may, to execute the decree.
Their sagacity is shown in a thousand ways, especially in the judicious and well-weighed choice of their abode. Those which I observed at Nantes, on one of the hills of the Erdre, passed over my head every morning, and returned every evening. Evidently they had their town and country houses. By day they perched on the cathedral towers to make their observations, ferreting out (éventant) what good things the city might have to offer. At close of day, they regained the woods, and the well-sheltered rocks where they love to pass the night. These are domiciliated people, and no mere birds of passage. Attached to their family, especially to their mates, to whom they are scrupulously loyal, their peculiar dwelling-place should be the nest. But the dread of the great birds of night decides them to sleep together in twenties or thirties—a sufficient number for a combat, if such should arise. Their special object of hate and horror is the owl; when day breaks, they take their revenge for his nocturnal misdeeds: they hoot him; they give him chase; profiting by his embarrassment, they persecute him to death.
There is no form of association by which they do not know how to profit. That which is sweetest—the family—does not induce them to forget, as you may see, the confederacy for defence or the league for attack. On the contrary, they associate themselves even with their superior rivals, the vultures, and call, precede, or follow them, to feed at their expense. They unite—and this is a stronger illustration—with their enemy the eagle; at least, they surround him to profit by his combats, by the fray in which he triumphs over some great animal. These shrewd spectators wait at a little distance until the eagle has feasted to his satisfaction, and gorged himself with blood; when this takes place, he flies away, and the remainder falls to the crows.
Their evident superiority over so great a number of birds is due to their longevity and to the experience which their excellent memory enables them to acquire and profit by. Very different to the majority of animals, whose duration of life is proportionable to the duration of their infancy, they reach maturity at the end of a year, and live, it is said, a century.
The great variety of their food, which includes every kind of animal or vegetable nutriment, every dead or living prey, gives them a wide acquaintance with things and seasons, harvests and hunts. They interest themselves in everything, and observe everything. The ancients, who lived far more completely than ourselves in and with nature, found it no small profit to follow, in a hundred obscure things where human experience as yet affords no light, the directions of so prudent and sage a bird.
