A decoy actuating apparatus includes a decoy line actuating mechanism having a mechanism housing and a mechanism housing interior in the mechanism housing. A catch pin track is in the mechanism housing and communicates with the mechanism housing interior. The catch pin track has a line engaging track portion and a line disengaging track portion. A catch pin plate is disposed for rotation in the mechanism housing interior of the mechanism housing. A plate drive motor drivingly engages the catch pin plate for rotation. A catch pin slot is in the catch pin plate. An actuating line space is between the catch pin plate and the mechanism housing. A catch pin is disposed for sliding displacement in the catch pin slot of the catch pin plate and interfaces with the catch pin track. The catch pin is deployed in a line catching position and protrudes into the actuating line space when engaging the line engaging track portion. The catch pin is deployed in a line releasing position and clears the actuating line space when engaging the line disengaging track portion of the catch pin track. A decoy actuating line extends through the actuating line space. The decoy actuating line can be attached to a decoy to pull and release the waterfowl decoy and impart a lifelike feeding or diving motion to the decoy.
