In droves and skeins and sords and doles, gleans, lofts, coffles, fevers, mysteries, shoals, by murders, bevies, drifts, mischiefs, as clews, as swarms, like living chainmail spread across the scene. The many separate but uniform configure one flexible screen to which each body fastens by the rivet of its eye, by the rivet of its melting mind forged and recast by instinct. Separate uniform animals or one animal many times reflected. Whatever they’re made of canceling whatever the ground is made of, silver or feathers or fins revising the surface under them till it is nothing or nothing familiar, face of the gravel, the river, air stuttered through chinks in the swarm is refracted, resolved or nearly remembered foliage recovered to the blasted tree by the flocked rooks settling.
