Mojo Outdoors Crow Decoy - The Mojo Crow uses a dual shaft, direct drive motor system. Features a built in 1.5 seconds on and 1.5 seconds off cycler and magnetic wings. The built in cycle with the on / off feature mimics a crow fighting or poaching on other injured prey, which causes other crow to join in. The magnetic wings just slide onto motor shaft quickly and eliminates timely set ups. Operates on 6 AA batteries (not included).
