A flapping wing water fowl or migratory bird decoy set is disclosed. The decoy set includes a decoy and a mounting base. The decoy includes a body, a pair of wings, a motor assembly, a battery, and a waterproof control module. An exemplary bird is a goose. The body is constructed of a predetermined plastic material with hyper-realistic exterior ornamentation, and is arranged in a predetermined orientation to simulate a goose. The decoy has a pair of flappable decoy wings connected to the decoy body, the decoy wing being constructed and arranged to simulate the wing of a waterfowl or migratory bird. The control and power module is plug and play software controllable. The decoy is mountable on a male type member post via a female type receptacle on the decoy body. The decoy has a biased stabilizer cord that also mimics the legs of the waterfowl or migratory bird. The motor is mechanically coupled to the wings via a belt drive arrangement which yields a quiet decoy.
