A wind-driven decorative feature mounted inside the rotating head of an upright, standpipe-type sprinkler. The wind-driven device is mounted inside the sprinkler head for rotation independent of the rotation of the spray tubing portion of the sprinkler head, and is generally located in the region bounded by the rotation of the sprinkler head itself and the spray pattern emitted by the sprinkler head.
