A motorized decoy provides lifelike feeding motion by rotating or pivoting a decoy head in and out of water. The motor releasably couples to the decoy head such that the decoy head is rotated in the rearward direction when the motor is coupled to the decoy head and in the forward direction when the motor is decoupled. The motor decouples from the head when encountering a decoupling force above a preset threshold. The decoy body can bob in, and changes its orientation relative to, the water as the decoy head pivots. The decoy head can also pause under the surface of the water before rising up from the water.

The present invention is a decoy system that simulates waterfowl taking off and landing byway of a string, pulley and spring which collectively cause a crossbeam holding waterfowl decoys to raise and lower relative to the surface of the water in which the system sits. When the string is pulled one end of the crossbeam holding one decoy lowers and the opposite end of the beam holding either a counterweight or another decoy raises. When the string is released a spring attached to the opposite side of the beam from the string moves the beam towards its original position and thereby the string and spring actuate a teetering motion that provides a visual que on both sides of the hinge at the midpoint of the crossbeam.
