A Tap Against the Line

The ground was cool. Very smooth. I blinked, then waited. Nothing moved... until I tried shifting my weight. My feet pressed down, soft and quiet. Ahead lay a thin, dark line cut into the stone. I leaned forward, slow and cautious, lowering my beak until it gently tapped the seam. A tiny click. I can move, after all. I settled back, watching the quiet floor.
