A waterfowl decoy having a keel for the production of automatic motion is provided. The waterfowl decoy comprises a body, a chest or forward facing region, a tail or rearward facing region, a ventral surface or downward facing region, and a keel affixed to the ventral surface of the waterfowl decoy. When submerged in water, Bernoulli forces act on the keel translating to the ventral surface and generating automatic motion in the waterfowl decoy.
