Abstract: An animated duck decoy having a mechanism employing a driver gear having gear teeth disposed on half its periphery, the other half being without teeth, which engages a driven gear mounted on the same axle with a grooved wheel to wind and unwind a cord attached to an anchor in order to produce repetitive movement of the decoy. The animated duck decoy may be disposed to simulate a diving duck by attaching the cord to an anchor which can be placed on the bottom of a body of water. The animated duck decoy also may be disposed to simulate one duck chasing another duck by tethering it to a tree and attaching the cord to a conventional duck decoy which is tethered to a second tree by an elastic cord.
