When the wild ducks or the wild geese migrate in their season, a strange tide rises in the territories over which they sweep. As if magnetized by the great triangular flight, the barnyard fowl leap a foot or two in the air and try to fly. The call of the wild strikes them with the force of a harpoon and a vestige of savagery quickens their blood. All the ducks on the farm are transformed for an instant into migrant birds, and into those hard little heads, till now filled with humble images of pools and worms and barnyards, there swims a sense of continental expanse, of the breadth of the seas and the salt taste of ocean wind. The duck totters to right and left in its wire enclosure, gripped by a sudden passion to perform the impossible and a sudden love whose object is mystery.Antoine de Saint-Exupéry, Wind, Sand and Stars
