Just their appearance is intimidating for these animals, as ravens and crows are their natural enemies, which they tend to avoid. When an animal approaches, the radar motion sensor is triggered, and the decoy emits a realistic crow call. The solar panel powers the integrated battery. Simply place the crow in a sunny spot. You can turn off the crow with the switch, for example at night, so that neighbors are not disturbed. A ground spike is included for securing it to the ground or a flower box. Protect building facades, ledges, window sills, roofs, balconies, carports, gardens, and flower beds.
