The invention relates to a bird repellent device, in particular to a sound-light bird repellent machine which comprises a base, a supporting rod, a bearing pedestal and a multi-edge reflector. The lower end of the supporting rod is fixedly connected with the base. The upper end of the supporting rod is sleeved with the bearing pedestal. Transverse rods extending in the radial direction of the supporting rod are evenly distributed on the bearing pedestal. Wind bowls are arranged at the tail ends of the transverse rods. The multi-edge reflector is arranged on the top of the bearing pedestal. The inner surfaces of the wind bowls are concave arc-shaped faces. An orange-peel-shaped reflecting metal film is arranged on each concave arc-shaped face. Bells are arranged in the wind bowls. The sound-light bird repellent machine is firm, durable, small in size, compact and simple in structure and large in bird-repellent range; through the common effect of sound and light, the bird repellent machine is not influenced by weather change situations, is good in bird-repellent effect and can be widely applied to transmission overhead lines.
