PROBLEM TO BE SOLVED: To provide a strong and widely usable device for repelling birds by utilizing a ultrasonic wave disliked by the birds. SOLUTION: This device for repelling the birds from coming flying is obtained by allowing a stood shaft rod to support a spherical body, and installing a wave-transmitting device for generating the wave motion repelled by the birds and wind blades for rotating the spherical body, on the surface of the spherical body. Solar cells are installed in the spherical body to provide a driving power source for the wave-transmitting device. Ultrasonic waves are generated from the wave-transmitting device.
