Down from power lines a broad shadow tumbles to the ground. A thousand feathers rustle as the wings of the flock are tucked. On the sidewalk, in the green grass, a hundred spotted throats peck. In the rout moths flash the red undersides of their wings from inside ivory beaks. Curling worms and millipedes clutch the air, moist soil crumbing off their shiny segments. From their places the sudden flock, a wave breaking, swarms up like fallen leaves exploding back onto a tree.
