A reciprocating decoy movement device which has a swivel arm mounted on a pivot post extending upwardly from a base plate, and a drive bar rotatably mounted on a drive shaft extending upwardly from the base plate, the drive bar having an upwardly extending drive post slidably fitted in a guide channel disposed on the underside of the swivel arm, such that rotation of the drive bar moves the drive pin through a circle while sliding in the guide channel, thereby causing the swivel arm to move reciprocally from side-to-side.
