Abstract: An apparatus for flying a flying body imitating a raptor such as a hawk and an eagle to scare birds such as doves and crows to inhibit these birds from approaching. Concretely, the flying body is mounted to a hanging wire is adjusted in rotational speed and paying-out amount whereby a highly varying flying mode is realized, and a guide rail is constructed in a desired configuration to permit the flying body to be mounted to a self-propelled device housed in the guide rail or to a drive cable whereby the flying body is made to fly along the guide rail. Further, a power source of the apparatus is controlled by a timer or an illumination sensor, which acts to measure outdoor illumination, to enable the flying body to fly in conformity with a period of time, in which birds are active, so that the apparatus is made reasonable. In addition, a sensor is installed which senses approaching birds, and a sensing signal by the sensor permits the flying body to fly, so that it is possible to achieve power saving.
