An animated duck decoy including a decoy base, and a shell removably connected to the base. The shell defining a chamber. An upper bracket attached to an upper surface of the chamber, a tail member connected to an end of a horizontal rod that outwardly extends from a rear of the shell, and an opposite end of the rod connected to a torsion spring, the torsion spring also connected to the upper bracket, the rod further defining an open end. A lower bracket attached to a top surface of the base. The lower bracket having a motor attached thereto, the motor having a drive shaft extending vertically upward from the lower bracket, and the drive shaft having a hub fixed at the top end thereof. The hub having a horizontal arm including a first elastomeric bumper affixed at one end. The horizontal arm is spaced from the lower bracket such that the horizontal arm and the horizontal rod are substantially co-planar, so when the motor rotates the arm in a circular direction, the first bumper strikes the free end of the horizontal rod causing the horizontal rod to rotate horizontally and thus causing the tail member to rotate horizontally.
