FIELD: agriculture.
SUBSTANCE: invention relates to the field of objects protection against birds and is aimed at reduction of consumed energy, reduction of sound signal annoying effect duration, increased reliability and service lift of device that realises the method. Method for scaring of birds includes sudden action of sound signal generated with certain time intervals, in period of time, when highest harm is expected for the object from birds. Signals and time intervals between them are created by means of kinetic energy of atmospheric air, and thermal energy of the latter is used to form beginning and end of signal action.
EFFECT: solar radiation is used to form beginning and end of signal action, and this formation is related to height of sun station over horizon, and also solar radiation is concentrated or scattered.
