The invention discloses a high-altitude bird repeller for a power iron tower. The high-altitude bird repeller comprises a fixing frame, a power windmill and a simulated bird, wherein the fixing frame comprises a base and a supporting rod; a fixing hole is formed in the base; and one end of the supporting rod is connected with the base, and the other end of the supporting rod is connected with the simulated bird. Fan blades drive a fan to mechanically charge a storage battery; and meanwhile, a movable rod drives wings to flutter, a storage battery supplies power to a sound production device and a light emitting device, the sound production device can produce a loud eagle sound, and the light emitting device can emit flickering light, so that the aim of effectively repelling birds is fulfilled. The high-altitude bird repeller for the power iron tower is simple in structure, economical and practical.
